Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.
References herein to "a plurality" means two or more. "and/or" describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate that there are three cases of a alone, a and B together, and B alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.
First, the terms involved in the embodiments of the present application will be briefly explained.
When a measurement object or a reference signal, i.e. a serving cell or a neighbor cell, is a New Radio (NR) cell, when a terminal in SSB (synchronization signal/physical broadcast channel block, SS/PBCH block) 5G performs cell measurement, the terminal performs cell measurement by receiving SSB corresponding to the serving cell or the neighbor cell. Wherein the fixed bandwidth of the SSB is 20RB, and the period can be configured to be 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms. Optionally, in NR, the base station adopts a beam scanning manner when broadcasting signals, and at a certain moment, energy is directed in a certain direction, so as to implement coverage of the whole cell by continuously changing the beam direction. Taking SSB period of 5ms as an example, there are L SSBs (numbered 0~L-1) in the 5ms period, and SSBs with different numbers correspond to different beam directions. Fig. 1 is a schematic diagram illustrating a time-sharing transmission process of reference signals with different direction angles according to an exemplary embodiment of the present application. As can be seen from fig. 1, l=8, and each period has 8 SSBs (numbered SSB0 to SSB 7), and the SSBs with different changes correspond to different beam directions, for example, the beam direction corresponding to SSB0 is clockwise 0 ° (black part), the beam direction corresponding to SSB1 is clockwise 45 °, the beam direction corresponding to SSB2 is clockwise 90 °, the beam direction corresponding to SSB3 is clockwise 135 °, the beam direction corresponding to SSB4 is clockwise 180 °, the beam direction corresponding to SSB5 is clockwise 225 °, the beam direction corresponding to SSB6 is clockwise 270 °, and the beam direction corresponding to SSB7 is clockwise 315 °.
Optionally, the value of L is determined by the frequency range of the cell frequency point corresponding to the cell, and the relationship between the value of L and the frequency range may be as shown in table one.

3GHz≤f<6GHz 8
f>6GHz 64
In the embodiment of the application, the principle that each beam (wave beam) of the reference signal of the NR system is transmitted in different direction angles is fully utilized, and when the corresponding terminal is at different positions of the cell, the time position and the measured value of the corresponding reference signal of the cell in each wave beam direction have a specific relative strong and weak relation, so that the continuous statistics of the signal intensity or the time position can be carried out through a plurality of measured beams of each cell so as to determine whether the terminal is in a static state. Schematically, as shown in fig. 2, a schematic diagram of characteristics of a measured beam of a specific cell in time position and signal strength of a terminal in a stationary condition according to an exemplary embodiment of the present application is shown. As can be seen from fig. 2, if the terminal is stationary in the specific cell, the relative time position of each measurement beam (SSB) in the specific cell is fixed, and the signal relative strength relationship of the reference signals in different beam directions is fixed, for example, if the terminal faces the beam direction in which SSB4 is located, the signal strength of beam4 is strongest, the signal strength of beam3 or beam5 is equivalent, and the signal strength of beam0 is weakest.
Fig. 3 shows a block diagram of a communication system provided by an exemplary embodiment of the present application, which may include an access network 32 and a terminal 33.
Several network devices 320 are included in access network 32. The network device 320 may be a base station, which is a device deployed in an access network to provide wireless communication functionality for terminal devices. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. The names of base station-capable devices may vary in systems employing different radio access technologies, such as in long term evolution (Long Term Evolution, LTE) systems, referred to as evolved Node bs (enodebs) or enbs, and in 5G NR-U systems, referred to as gNodeB or gNB. As communication technology evolves, the description of "base station" may change. For convenience, the above-described devices for providing the wireless communication function to the terminal 33 are collectively referred to as a network device.
The terminal 33 can include various handheld devices, vehicle mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment, mobile Stations (MSs), terminal devices (TERMINAL DEVICE), and the like, having wireless communication capabilities. For convenience of description, the above-mentioned devices are collectively referred to as electronic devices. The network device 320 and the terminal 33 communicate with each other via some kind of air interface technology, e.g. Uu interface.
The method for determining the static state of the terminal provided by the embodiment of the application is used for the terminal 33 in the communication system shown in fig. 3.
Referring to fig. 4, a flowchart of a method for determining a stationary state of a terminal according to an exemplary embodiment of the present application is shown. This embodiment is described by taking the terminal shown in fig. 3 as an example, and the process includes the following steps:
Step 401, obtaining a cell measurement result of a terminal on a target cell, where the target cell corresponds to at least two reference signals in different beam directions, and the cell measurement result includes a measurement result of the reference signals.
The basis for judging whether the terminal is stationary is that the principle that each beam of the reference signals in the NR system is transmitted in different direction angles is adopted, so that the terminal is positioned at different positions of an NR cell, and the measurement results of each beam are different. The present embodiment is exemplified by taking the target cell as a cell in the NR system, and as the communication system evolves, the target cell may not be a cell in the NR system.
As can be seen from the broadcast characteristics of the NR cell reference signals shown in fig. 1 and 2, when the terminal moves during the measurement of the neighboring cells, there is necessarily a difference between the cell measurement results of the neighboring cells of the terminal, and therefore, when the terminal can determine whether the terminal is in a stationary state by comparing the difference between the two measurement results of the terminal on the target cell, in a possible implementation manner, when the terminal completes at least two cell measurements, at least two cell measurement results of the terminal on the target cell can be selected from the cell measurement results, so that the terminal can be determined whether to be in a stationary state by comparing the difference between the at least two cell measurement results. The target cell corresponds to reference signals with different beam directions, and the corresponding cell measurement result at least comprises measurement results of the terminal on the reference signals with different beam directions. Such as RSRP (REFERENCE SIGNAL RECEIVING Power of reference Signal), RSRQ (REFERENCE SIGNAL RECEIVING Quality of reference Signal reception Quality), SNR (Signal-to-Noise Ratio), RSSI (RECEIVED SIGNAL STRENGTH Indication), time position, and the like of the reference Signal.
Since the terminal itself can periodically perform cell measurement in the use process, and the cell measurement period can meet the frequency requirement of terminal standstill determination, in order to not increase cell measurement power consumption additionally, in a possible implementation manner, a determination process of a terminal standstill state is performed according to the cell measurement results of two adjacent times, that is, the terminal standstill determination period is consistent with the cell measurement period.
In one exemplary example, the 1 st terminal stationary state determination is made based on the 1 st cell measurement result and the 2 nd cell measurement result, the 2 nd terminal stationary state determination is made based on the 2 nd cell measurement result and the 3 rd cell measurement result, and so on, and it can be seen that the time interval of the two terminal stationary state determinations is the time interval of the single cell measurement.
The cell measurement result of the terminal may not only include the measurement result of the serving cell, but also include the measurement result of the neighbor cell, and the corresponding target cell may be the serving cell, the neighbor cell, or both the serving cell and the neighbor cell where the terminal currently resides.
Optionally, under the condition that the signal quality of the service cell where the terminal currently resides is better, the terminal does not need to prepare for cell reselection or cell handover, measurement of a neighboring cell is not required to be started, the terminal only performs periodic measurement on the service cell, and the target cell is the service cell where the terminal currently resides.
Optionally, when the terminal starts the neighbor cell measurement, the cell measurement result of the terminal may include measurement results of a serving cell and a plurality of neighbor cells, and a cell with poor signal strength may exist in the plurality of neighbor cells, so as to improve accuracy of terminal rest state judgment, a cell with good signal quality may be screened from the cell measurement results, and the cell may be used as a target cell for subsequent terminal rest state judgment.
Alternatively, the number of the target cells may be 1, or may be two or more. The greater the number of target cells, the relatively higher the accuracy of the stationary state decision.
Step 402, determining a target measurement difference value corresponding to the target cell based on at least two cell measurement results of the target cell, wherein the target measurement difference value represents the difference of reference signals in different beam directions in the at least two measurement results.
In one possible implementation manner, after at least two cell measurement results of the target cell are obtained, a target measurement difference corresponding to the target cell may be determined by comparing differences of reference signals in different beam directions in the at least two measurement results, so as to determine whether the terminal moves through the target measurement difference.
The target measurement difference may be a signal strength difference between the same reference signal in at least two measurement results, a difference of a relative strength relationship between different reference signals in at least two measurement results, a difference of a time position of the same reference signal in at least two measurement results, or at least one of the three differences.
Step 403, determining that the terminal is in a stationary state during at least two cell measurements, in case the target measurement difference is below a target measurement threshold.
In theory, if the terminal is in a static state during the measurement of the two adjacent cells, the measurement results of the terminal on the target cell should be the same, that is, the reference signals in different beam directions in the two measurement results are the same, and there is no difference, but in consideration of possible measurement errors in the practical application process, a smaller difference is allowed between the two measurement results. Therefore, in order to accurately determine whether the terminal is in a stationary state, in one possible implementation manner, a target measurement threshold is set, by comparing the relation between the target measurement difference value and the target measurement threshold, if the target measurement difference value is lower than the target measurement threshold, the two measurement results of the terminal are similar within the error allowable range, and it can be further determined that the terminal is not moved during at least two cell measurements and is in a stationary state.
Optionally, in order to improve accuracy of determining the stationary state of the terminal, a difference value between the cell measurement results at least two times may be determined through multiple dimensions, a plurality of target measurement difference values are correspondingly calculated, and if at least one target measurement difference value in the plurality of target measurement difference values is greater than a target measurement threshold value, a determination result that the terminal may be in a moving state is output.
Optionally, since the target measurement difference may include multiple dimensions (such as a signal strength difference, a time position difference, a difference of a relative strength relationship, etc.), when determining a terminal rest state, different target measurement thresholds are also required to be set for the target measurement difference of different dimensions.
Optionally, when determining the terminal position state, at least one target measurement difference value may be selected according to the actual requirement to determine, and the more kinds of target measurement difference values are used, the higher the accuracy of the terminal position state determination is.
In summary, in the embodiment of the present application, a method for determining whether a terminal is stationary based on a cell measurement result is provided in the embodiment of the present application, by acquiring at least two measurement results of the terminal on a target cell, since the target cell corresponds to reference signals in different beam directions and the terminal moves during two cell measurements, there is necessarily a difference between the reference signals in different beam directions received by the terminal, so that the difference between the reference signals in different beam directions in the target cell at least two measurement results can be compared with a set target measurement threshold, and thus the terminal can be determined to be in a stationary state under the condition that the target measurement difference is smaller.
When evaluating the difference of the reference signals in different beam directions in at least two measurement results, the evaluation can be performed from multiple data dimensions, for example, the difference of the signal intensities in the same beam direction in the two measurement results is directly compared, or the difference of the signal strength relationship between different beam directions in the two measurement results is compared, or the time position difference of the reference signals in the same beam direction in the two measurement results is compared, and the following embodiments respectively perform exemplary explanation on the terminal static state judgment from the three aspects.
Referring to fig. 5, a flowchart of a method for determining a stationary state of a terminal according to another exemplary embodiment of the present application is shown. This embodiment is described by taking the terminal shown in fig. 3 as an example, and the process includes the following steps:
Step 501, obtaining a cell measurement result of a terminal on a target cell, where the target cell corresponds to at least two reference signals in different beam directions, and the cell measurement result includes a measurement result of the reference signals.
The implementation of step 501 may refer to the above embodiments, and this embodiment is not described herein.
Step 502, obtaining first signal strengths of target reference signals in M different beam directions from a first cell measurement result, where M is an integer greater than 1 and less than or equal to a beam number threshold, and the beam number threshold is determined by a frequency range of a cell frequency point corresponding to the target cell.
The at least two cell measurement results of the target cell may be two adjacent cell measurement results of the terminal on the target cell, for example, the at least two cell measurement results are an i-1 th cell measurement result and an i-1 th cell measurement result, or may be two cell measurement results separated by the target measurement times, for example, the at least two cell measurement results are an i-1 th cell measurement result and an i+1 th cell measurement result. For convenience of explanation, in this embodiment, the case where the at least two cell measurement results include a first cell measurement result and a second cell measurement result is taken as an example, the first cell measurement result corresponds to the i-th cell measurement result, and the second cell measurement result corresponds to the i-1-th cell measurement result.
Since the NR cells correspond to reference signals in different beam directions, if the terminal moves during two cell measurements, the signal strengths indicated by the two test results of the reference signals in the same beam direction are different, whereas if the terminal is in a stationary state during two cell measurements, the signal strengths indicated by the two test results of the reference signals in the same beam direction should be the same or similar (less different), so in a possible implementation, it may be judged whether the terminal is in a stationary state by comparing the signal strength differences between the target reference signals in the same beam direction in the two measurement results. In order to further improve the accuracy of determining the stationary state of the terminal, the signal strength differences between the target reference signals in the plurality of different beam directions can be obtained from the target cell for comparison, and correspondingly, first signal strengths of the target reference signals in the M different beam directions in the target cell are obtained from the first cell measurement result so as to be compared with the signal strengths in the second cell measurement result. The first signal strength is the signal strength of the M target reference signals.
Optionally, the value of M is an integer greater than 1 and less than or equal to a beam number threshold, where the beam number threshold is determined by a frequency range of a cell frequency point corresponding to the target cell (in table 1), for example, if the frequency range of the cell frequency point corresponding to the target cell is located at 3ghz to 6ghz, the relationship between the frequency range and the value of L shown in table 1 indicates that the beam number threshold corresponding to the target cell is 8, and the value of M may be 2, 3, 6, 8, and so on.
Alternatively, the signal strength of the target reference signal may be represented by the RSRP parameter of the target reference signal.
Step 503, obtaining second signal strengths of the target reference signals in M different beam directions from the second cell measurement result.
In order to compare the difference in signal strength between the two measurements of the target reference signal in the same beam direction, in one possible embodiment, it is also necessary to obtain second signal strengths of the target reference signals in M different beam directions in the target cell from the second cell measurements for comparison with the signal strengths in the first cell measurements. The second signal strength also includes signal strengths of the M target reference signals.
It should be noted that, step 502 and step 503 may be performed simultaneously, or step 502 may be performed, and step 503 is performed, which is not limited in this embodiment of the present application.
Taking at least two cell measurement results as an i-th cell measurement result and an i-1-th cell measurement result as examples, the terminal can acquire the first signal strength from the i-th cell measurement result and acquire the second signal strength from the i-1-th cell measurement result.
Alternatively, the second signal strength may be obtained by performing filtering processing on the i-2 th cell measurement result and the i-1 th cell measurement result, that is, after the terminal standstill state is determined based on the i-2 th cell measurement result and the i-1 th cell measurement result, filtering processing may be performed according to the i-2 th cell measurement result and the i-1 th cell measurement result, and the cell measurement result after the filtering processing is updated to the i-1 th cell measurement result.
Step 504, determining a first signal strength difference of the target reference signal in the same beam direction in the adjacent two measurement results based on the first signal strength and the second signal strength.
In one possible implementation manner, after obtaining the second signal strengths of the target reference signals in different beam directions in the second cell measurement result (the last measurement result or the last filtering result) and the first signal strengths of the target reference signals in different beam directions in the first cell measurement result (the current measurement result), the first signal strengths and the second signal strengths in each same beam direction may be compared, so as to determine the first signal strength difference value of the target reference signals in each same beam direction in two adjacent measurement results.
In one illustrative example, taking m=8 as an example, if the first signal strengths are RSRP Beam0、RSRPBeam1、RSRPBeam2、RSRPBeam3、RSRPBeam4、RSRPBeam5、RSRPBeam6 and RSRP Beam7 (where RSRP Beam0 may represent the signal strength of the reference signal in the beam direction numbered 0 in the ith cell measurement), the second signal strengths are :RSRP′Beam0、RSRP′Beam1、RSRP′Beam2、RSRP′Beam3、RSRP′Beam4、RSRP′Beam5、RSRP′Beam6 and RSRP 'Beam7 (where RSRP' Beam0 may represent the signal strength of the reference signal in the beam direction numbered 0 in the ith-1 cell measurement), the first signal strength difference may be :RSRPBeam0-RSRP′Beam0、RSRPBeam1-RSRP′Beam1、RSRPBeam2-RSRP′Beam2、RSRPBeam3-RSRP′Beam3、RSRPBeam4-RSRP′Beam4、RSRPBeam5-RSRP′Beam5、RSRPBeam6-RSRP′Beam6 and RSRP Beam7-RSRP′Beam7.
Optionally, the first signal strength difference may be an absolute value of a difference between the first signal strength and the second signal strength, so that a subsequent threshold comparison is facilitated.
In step 505, it is determined that the terminal is in a stationary state during at least two cell measurements, in case the first signal strength difference corresponding to the target cell is below the first measurement threshold.
In theory, if the terminal is in a stationary state during two cell measurements, the difference between the signal strengths between the two measurements should be infinitely close to 0, and considering the measurement error of the terminal, in one possible embodiment, a first measurement threshold is provided, and when each of the first signal strength differences is lower than the first measurement threshold, it may be indicated that the two measurements of the terminal are approximate, and it is determined that the terminal is in a stationary state during at least two cell measurements.
The first measurement threshold may be set by a service person or a developer according to requirements, for example, the first measurement threshold may be 0.5db.
Optionally, when the number of the target cells is 1, the decision result of the terminal in the static state can be output when the first signal intensity differences corresponding to the target cells are smaller than the first measurement threshold after the decision is completed, and when the number of the target cells is greater than 1, the decision result of the terminal in the static state can be output when the first signal intensity differences corresponding to the target cells are smaller than the first measurement threshold in order to further improve the accuracy of the decision of the terminal in the static state.
Optionally, in order to reduce the decision power consumption, in the process of comparing the first signal strength difference value corresponding to the target cell with the first measurement threshold value, as long as the first signal strength difference value is larger than the first measurement threshold value for the first time, the decision result that the terminal is in the moving state can be output, without performing the subsequent process of comparing other first signal strength difference values with the first measurement threshold value, or performing the process of comparing the first signal strength corresponding to other target cells with the first measurement threshold value.
In this embodiment, considering that if the terminal is in a stationary state during at least two cell measurements, signal strengths indicated by at least two test results of reference signals in the same beam direction should be the same or similar, by acquiring a signal strength difference value between target reference signals in each same beam direction and setting a first measurement threshold value, a relationship between the signal strength difference value and the first measurement threshold value is compared, and whether the two measurement results are similar is determined, so as to output a decision result of whether the terminal is in a stationary state.
Considering that when the signal strengths of the target reference signals in the same beam direction are similar, there may be a difference in the relative strength relationships between the reference signals in different beam directions, and when there is a difference in the relative strength relationships between the signals, the two measurement results of the terminal are not similar, and the terminal may still be in a moving state, so in order to further improve the accuracy of the decision of the terminal in a static state, in a possible implementation, the step of comparing the relative strength relationships between the signals is additionally introduced in the decision process of the terminal in the static state.
Referring to fig. 6, a flowchart of a method for determining a stationary state of a terminal according to another exemplary embodiment of the present application is shown. This embodiment is described by taking the terminal shown in fig. 3 as an example, and the process includes the following steps:
Step 601, obtaining a cell measurement result of a terminal on a target cell, where the target cell corresponds to at least two reference signals in different beam directions, and the cell measurement result includes a measurement result of the reference signals.
Step 602, obtaining first signal strengths of target reference signals in M different beam directions from a first cell measurement result.
Step 603, obtaining second signal strengths of the target reference signals in M different beam directions from the second cell measurement result.
Step 604, determining a first signal strength difference of the target reference signal in the same beam direction in the two adjacent measurement results based on the first signal strength and the second signal strength.
The implementation of steps 601 to 604 may refer to the above embodiments, which are not described in detail in this embodiment.
Step 605, based on the first cell measurement, determines a second signal strength difference between the target reference signals in the M different beam directions.
As can be seen from fig. 2, when the terminal is located at a specific location in the NR cell, there is a specific relative strong-weak relationship between the signal strengths of the reference signals in different beam directions, for example, the signal strength in the beam direction corresponding to SSB4 is the strongest, that is, the signal strengths in the beam directions corresponding to SSB3 and SSB5 are equal, that is, there is a specific relationship between the signal strength differences between the reference signals in different beam directions, so that in order to further improve the accuracy of the decision of the terminal in the stationary state, in a possible implementation manner, whether the signal strength differences between the reference signals in M different beam directions in at least two measurement results are similar is further determined by comparing whether the signal strength differences between the reference signals in the two measurement results are similar. In order to obtain the difference between the relative strength of the signals between the at least two measurement results, it is first necessary to obtain the second signal strength difference between the target reference signals in the M different beam directions from the first cell measurement result.
For the second signal strength difference obtaining process, in one possible implementation manner, first, signal strengths corresponding to the target reference signals in the M different beam directions are obtained from the measurement result of the first cell, then, based on the signal strengths of the target reference signals in the adjacent beam directions, the signal strength difference between the target reference signals in the adjacent beam directions is determined, and so on, so as to obtain the second signal strength difference between the target reference signals in the different beam directions of the target cell.
In an exemplary example, taking m=8 as an example, in the measurement result of the ith cell, the signal strengths of the reference signals in the directions of the respective beams of the target cell are represented as RSRP Beam0、RSRPBeam1、RSRPBeam2、RSRPBeam3、RSRPBeam4、RSRPBeam5、RSRPBeam6 and RSRP Beam7 (where RSRP Beam0 may represent the signal strengths of the reference signals in the direction of the beam numbered 0 in the measurement result of the ith cell), the second signal strength difference may be represented as :RSRPBeam0-RSRPBeam1、RSRPBeam1-RSRPBeam2、RSRPBeam2-RSRPBeam3、RSRPBeam3-RSRPBeam4、RSRPBeam4-RSRPBeam5、RSRPBeam5-RSRPBeam6、RSRPBeam6-RSRPBeam7.
Alternatively, the second signal strength difference may take the absolute value of the signal strength difference between target reference signals in adjacent beam directions for subsequent threshold comparison.
Step 606 determines a third signal strength difference between the target reference signals in the M different beam directions from the second cell measurements.
In order to obtain the difference between the relative strength relationships of the signals between the two measurement results, it is further required to determine a third signal strength difference between the target reference signals in the M different beam directions from the second cell measurement result, so as to determine whether the relative strength relationships of the signals between the two measurement results are similar by comparing the third signal strength difference with the second signal strength difference.
Optionally, the third signal strength difference obtaining process is similar to the second signal strength difference obtaining process, in an exemplary example, if m=8, in the i-1 th cell measurement result, the signal strength of the reference signal corresponding to each beam direction of the target cell is denoted by :RSRP′Beam0、RSRP′Beam1、RSRP′Beam2、RSRP′Beam3、RSRP′Beam4、RSRP′Beam5、RSRP′Beam6 and RSRP 'Beam7 (where RSRP' Beam0 may denote the signal strength of the reference signal corresponding to the beam direction of 0 in the i-1 th cell measurement result), the third signal strength difference may denote that :RSRP′Beam0-RSRP′Beam1、RSRP′Beam1-RSRP′Beam2、RSRP′Beam2-RSRP′Beam3、RSRP′Beam3-RSRP′Beam4、RSRP′Beam4-RSRP′Beam5、RSRP′Beam5-RSRP′Beam6、RSRP′Beam6-RSRP′Beam7.
Taking at least two cell measurement results as an ith cell measurement result and an ith-1 cell measurement result as an example, the terminal may determine a second signal strength difference between target reference signals in M different beam directions based on the ith cell measurement result, and determine a third signal strength difference between target reference signals in M different beam directions from the ith-1 cell measurement result.
Alternatively, the third signal strength difference may be obtained directly from the i-1 th cell measurement, since the third signal strength difference may have already been calculated in the process of comparing the i-2 th cell measurement with the i-1 th cell measurement.
In step 607, a fourth signal strength difference is determined based on the second signal strength difference and the third signal strength difference.
In one possible implementation manner, after obtaining the signal relative strength relationship (the second signal strength difference) between the target reference signals in the different beam directions in the first cell measurement result and the signal relative strength relationship (the third signal strength difference) between the target reference signals in the different beam directions in the second cell measurement result, the second signal strength difference and the third signal strength difference may be compared to obtain a fourth signal strength difference, so as to determine whether the signal relative strength relationship between the two measurement results is similar.
In determining the fourth signal strength difference, a corresponding comparison is also required for the same set of beam directions. For example, if the second signal strength difference is denoted as RSRP Beam0-RSRPBeam1, then a comparison is required with RSRP' Beam0-RSRP′Beam1 in the third signal strength difference to determine the difference between the signal relative strengths of the reference signals in the beam directions numbered 0 and numbered 1 in the two measurements.
Step 608, determining that the terminal is in a stationary state during at least two cell measurements, if the first signal strength difference corresponding to the target cell is lower than the first measurement threshold and the fourth signal strength difference corresponding to the target cell is lower than the second measurement threshold.
Theoretically, if the terminal is in a static state during at least two cell measurements, the difference of signal intensities in the same beam direction between at least two measurements should be close to 0, and the difference of the relative strength relationships of signals in different beam directions between at least two measurements should be close to 0, and considering the measurement error of the terminal, in one possible implementation manner, a first measurement threshold and a second measurement threshold are provided, and when each first signal intensity difference is lower than the first measurement threshold and each fourth signal intensity difference is lower than the second measurement threshold, it may indicate that the at least two cell measurements of the terminal are similar, and the decision result that the terminal is in a static state during at least two measurements is output.
The second measurement threshold may also be set by a service person or a developer according to requirements, for example, the second measurement threshold may be 0.4db.
Optionally, when the number of the target cells is 1, the decision result of the terminal in the static state can be directly output when the first signal intensity differences corresponding to the target cells are smaller than the first measurement threshold value and the fourth signal intensity differences corresponding to the target cells are smaller than the second measurement threshold value after the decision is completed, and when the number of the target cells is greater than 1, the decision result of the terminal in the static state can be output when the first signal intensity differences corresponding to the target cells are smaller than the first measurement threshold value and the fourth signal intensity differences corresponding to the target cells are smaller than the second measurement threshold value in order to further improve the decision accuracy of the terminal in the static state.
Optionally, in order to reduce the decision power consumption in the decision process of the static state of the actual terminal, step 602 to step 604 may be performed first to determine a first signal strength difference value, and compare the relation between the first signal strength difference value and the first measurement threshold, if the first signal strength difference value of each target cell is lower than the first measurement threshold, step 605 to step 607 are continuously performed to determine a fourth signal strength difference value, and compare the relation between the fourth signal strength difference value and the second measurement threshold.
Optionally, step 605 to step 607 may be performed first to determine a fourth signal strength difference value, and compare the relation between the fourth signal strength difference value and the second measurement threshold value, if the fourth signal strength difference value of each target cell is lower than the second measurement threshold value, step 602 to step 604 are performed continuously to determine a first signal strength difference value, and compare the relation between the first signal strength difference value and the first measurement threshold value, and optionally, if the fourth signal strength difference value is greater than the second measurement threshold value, step 602 to step 604 are not required to be performed, and the decision result that the terminal is in a moving state is directly output, so that unnecessary determining and comparing processes of the first signal strength difference value can be reduced, and the decision power consumption of the terminal is further reduced.
Optionally, in order to improve the decision efficiency, step 605 to step 607 and step 602 to step 604 may be executed simultaneously, where when the first signal strength difference value of each target cell is lower than the first measurement threshold and the fourth signal strength difference value of each target cell is lower than the second measurement threshold, the decision result that the terminal is in the stationary state is output, otherwise, if the first signal strength difference value of the target cell is higher than the first measurement threshold and/or the fourth signal strength difference value of the target cell is higher than the second measurement threshold, the decision result that the terminal is in the moving state is output.
In this embodiment, by adding a difference decision of the relative strength relationship of the signals in the decision process of the terminal in the stationary state, the threshold for determining the similarity of the two measurement results is further improved, so as to further improve the decision accuracy of the stationary state of the terminal.
When the terminal is in a stationary state, the time difference between the reception timings (time positions) of the reference signals in the same beam direction by the terminal two times in succession should be fixed, that is, the reception timing of the i-th reference signal+the reference signal broadcast period=the i+1th reference signal reception timing; based on this feature, in order to further improve the decision accuracy of the terminal rest state, in one possible implementation, a time-position difference is introduced in the terminal rest state decision process.
Referring to fig. 7, a flowchart of a method for determining a stationary state of a terminal according to another exemplary embodiment of the present application is shown. This embodiment is described by taking the terminal shown in fig. 3 as an example, and the process includes the following steps:
Step 701, obtaining a cell measurement result of a terminal on a target cell, where the target cell corresponds to at least two reference signals in different beam directions, and the cell measurement result includes a measurement result of the reference signals.
Step 702, obtaining first signal strengths of target reference signals in M different beam directions from a first cell measurement result.
Step 703, obtaining second signal strengths of the target reference signals in M different beam directions from the second cell measurement result.
Step 704, determining a first signal strength difference of the target reference signal in the same beam direction in the two adjacent measurement results based on the first signal strength and the second signal strength.
Step 705, determining a second signal strength difference between the target reference signals in the M different beam directions based on the first cell measurement result.
Step 706, determining a third signal strength difference between the target reference signals in the M different beam directions from the second cell measurement.
Step 707, determining a fourth signal strength difference based on the second signal strength difference and the third signal strength difference.
The implementation manners of steps 701 to 707 may refer to the above embodiments, which are not described herein.
Step 708 determines a first time position of the target reference signal in M different beam directions from the first cell measurement.
When the terminal is in a stationary state, the time difference between the reception timings (time positions) of the reference signals in the same beam direction by the terminal two times in succession should be fixed, that is, the reception timing of the i-th reference signal+the reference signal broadcast period=the i+1th reference signal reception timing; based on this feature, in order to further improve the decision accuracy of the terminal rest state, in one possible implementation, a time-position difference is introduced in the terminal rest state decision process. In order to compare whether the time position deviation is within a preset threshold, first time positions of the target reference signals in the M different beam directions need to be determined from the first cell measurement result, and the first time positions also correspond to the receiving moments of the target reference signals.
Step 709 determines a second time position of the target reference signal in M different beam directions from the second cell measurement.
Similarly, a second time position of the target reference signals in M different beam directions needs to be determined from the second cell measurement result, that is, the receiving time of each target reference signal in the second cell measurement process.
Taking at least two cell measurement results as an i-th cell measurement result and an i-1-th cell measurement result as an example, the terminal can determine first time positions of target reference signals in M different beam directions from the i-th cell measurement result, and determine second time positions of target reference signals in M different beam directions from the i-1-th cell measurement result.
Step 710, determining a time position difference based on the first time position and the second time position.
When the terminal is in a stationary state, the difference between the first time position and the second time position is fixed, and is the broadcasting period of the target reference signal, and in order to compare whether there is a time position deviation between the first time position and the second time position, in a possible implementation manner, a third time position (ideal receiving time in a stationary state) of the target reference signal in the ith cell measurement process in the stationary state of the terminal can be determined based on the second time position and the broadcasting period, and then the time position deviation between the third time position and the first time position (actual time position) is compared, so as to determine the time position difference.
Step 711, determining that the terminal is in a stationary state during at least two cell measurements when the first signal strength difference corresponding to the target cell is lower than the first measurement threshold, the fourth signal strength difference corresponding to the target cell is lower than the second measurement threshold, and the time position difference corresponding to the target cell is lower than the third measurement threshold.
Theoretically, if the terminal is in a stationary state during two cell measurements, the difference of signal intensities in the same beam direction between the two measurements should be close to 0, the difference of the relative strength relationships of signals in different beam directions between the two measurements should be close to 0, and the time position deviation between the two measurements should be close to 0, and considering the measurement errors, in one possible implementation manner, a first measurement threshold, a second measurement threshold and a third measurement threshold are provided, and when each of the first signal intensity differences is lower than the first measurement threshold, each of the fourth signal intensity differences is lower than the second measurement threshold, and each of the time position differences is lower than the third measurement threshold, a decision result that the terminal is in a stationary state during at least two cell measurements may be output.
The third measurement threshold may also be set by a business person or a developer according to requirements, for example, the third measurement threshold may be 5ts.
Optionally, when the number of the target cells is 1, when the judgment is completed that the first signal intensity differences corresponding to the target cells are smaller than the first measurement threshold, the fourth signal intensity differences are smaller than the second measurement threshold, and the time position differences are smaller than the third measurement threshold, the judgment result that the terminal is in the static state can be directly output, and when the number of the target cells is greater than 1, in order to further improve the judgment accuracy of the terminal in the static state, the first signal intensity differences corresponding to the target cells are smaller than the first measurement threshold, the fourth signal intensity differences corresponding to the target cells are smaller than the second measurement threshold, and the time position differences corresponding to the target cells are smaller than the third measurement threshold, the judgment result that the terminal is in the static state can be output.
Optionally, in order to reduce the decision power consumption in the decision process of the static state of the actual terminal, step 702 to step 704 may be performed first, a relation between the first signal strength difference and the first measurement threshold is determined, if the first signal strength difference of each target cell is lower than the first measurement threshold, step 705 to step 707 is continuously performed, a fourth signal strength difference is determined, and the relation between the fourth signal strength difference and the second measurement threshold is compared, if the fourth signal strength difference of each target cell is lower than the second measurement threshold, step 708 to step 710 is continuously performed, and optionally, if the first signal strength difference is greater than the first measurement threshold, step 705 to step 710 is not required to be performed, the decision result of the terminal in the moving state is directly output, and the unnecessary determination and comparison process of the fourth signal strength difference and the time position difference can be reduced, thereby further reducing the decision power consumption of the terminal. Optionally, if the first signal strength difference is lower than the second measurement threshold, but the fourth signal strength difference is greater than the second measurement threshold, the decision result of the terminal in the moving state may be directly output, without executing steps 708-710, so that an unnecessary time-position difference determining process is avoided, and decision power consumption of the terminal is reduced.
Optionally, in order to improve the decision efficiency, step 705 to step 707, step 702 to step 704 and step 708 to step 710 may be performed simultaneously, where when the first signal strength difference value of each target cell is lower than the first measurement threshold, the fourth signal strength difference value of each target cell is lower than the second measurement threshold, and the time position difference value of each target cell is lower than the third measurement threshold, the decision result that the terminal is in the stationary state is output, otherwise, if the first signal strength difference value of the target cell is higher than the first measurement threshold, and/or the fourth signal strength difference value of the target cell is higher than the second measurement threshold, and/or the time position difference value of the target cell is higher than the third measurement threshold, the decision result that the terminal is in the moving state is output.
It should be noted that, in this embodiment, the case where the at least two cell measurement results include the first cell measurement result and the second cell measurement result is taken as an example, that is, only the difference between the two cell measurement results is used to determine whether the terminal is in the stationary state, in order to further improve the accuracy of the stationary state of the terminal, in other possible embodiments, it may also be determined whether the terminal is in the stationary state based on the cell measurement results of three or more times. For example, whether the terminal is in a stationary state is judged according to the i-1 th cell measurement result, the i-1 th cell measurement result and the i+1 th cell measurement result.
In this embodiment, whether the terminal is in a static state is commonly determined from three dimensions of time position deviation, signal strength deviation, signal relative strength relation deviation and the like, and the condition threshold of the output terminal in the static state is increased, so that the accuracy of terminal static state determination can be further improved.
Since the terminal may start measurement on the neighbor cells during the cell measurement process, there are multiple cell measurement results in the cell measurement results currently acquired by the terminal, if the cell measurement results of all candidate cells included in the cell measurement results are selected, the decision of the rest state of the subsequent terminal is performed, the decision power consumption of the terminal obviously will be increased, and some cells may still exist in the candidate cells, and if the measurement results of the candidate cells with poor signal quality are introduced, the decision accuracy of the rest state of the terminal will also be affected, so in a possible implementation manner, after the measurement results of all cells acquired by the terminal during the ith cell measurement process are acquired, the target cell and the corresponding cell measurement result that need to be used for performing the subsequent decision process need to be selected from among them.
Referring to fig. 8, a flowchart of a method for determining a stationary state of a terminal according to another exemplary embodiment of the present application is shown. This embodiment is described by taking the terminal shown in fig. 3 as an example, and the process includes the following steps:
step 801, obtaining a candidate cell measurement result of at least one candidate cell obtained by the terminal in a cell measurement process.
Since there may be a plurality of cell measurement results (serving cell and a plurality of neighbor cells) in the cell measurement results currently acquired by the terminal, if the cell measurement results of all candidate cells included in the cell measurement results are selected to perform the decision of the rest state of the terminal, the terminal decision power consumption will be increased, and if the cell measurement results of the candidate cells with poor signal quality are introduced, the decision accuracy of the rest state of the terminal will also be affected.
Step 802, selecting a cell measurement result of the target cell from the candidate cell measurement results.
When selecting a target cell required by a subsequent decision process from the candidate cell measurement results, the requirements of decision efficiency and decision accuracy are integrated, and in a possible implementation manner, two factors of the number of the selected cells and the cell signal strength can be comprehensively considered, the target cell is selected from the candidate cell measurement results, and the measurement result of the target cell is determined as a cell measurement result.
Since the decision of the terminal static state is periodically performed in real time, if the decision result output in the last terminal static state decision process before the measurement of the ith cell is that the terminal is in a static state, the terminal is more likely to be in a static state during the measurement of the ith cell, and then the target cell participated in the last terminal decision result can be selected from the candidate cell measurement results, and the difference of the target cells can be directly compared without reselecting the target cell which needs to participate in the decision process. Otherwise, if the last output decision result is that the terminal is in a mobile state, during the measurement of the ith cell, the terminal is more likely to be in a mobile state, and the target cell participating in the decision process needs to be reselected. In an illustrative example, step 802 may include steps 802A-802C.
Step 802A, obtaining a historical terminal state corresponding to a terminal.
The historical terminal state can be an initial terminal state, wherein the initial terminal state is generally set to be a mobile state, or the historical terminal state can also be a terminal state output by the last terminal static judgment process. In a possible implementation manner, the historical terminal state of the terminal is obtained to further determine whether the target cell participating in the decision process needs to be reselected in the decision process.
Step 802B, selecting a cell measurement result of the target cell from the candidate cell measurement results based on the history cell measurement results in the case that the history terminal state indicates that the terminal is in a stationary state.
The historical cell measurement result is the cell measurement result of the target cell participating in the last terminal static judgment process. If the at least twice cell measurement results are the i-1 th cell measurement result and the i-th cell measurement result, when the i-th cell measurement result is determined, the cell measurement result of the target cell can be selected from the candidate cell measurement results based on the i-1 th cell measurement result.
When the last decision result indicates that the terminal is in a stationary state, the terminal is more likely to be in the stationary state during the present cell measurement, it is only required to compare whether the measurement results of the target cells participating in the last decision process are different, that is, whether the terminal moves during the ith cell measurement can be determined, and in a possible implementation manner, when the terminal state indicates that the terminal is in the stationary state, the i-1 th cell measurement result may be based on the i-1 th cell measurement result (the historical cell measurement result), the i-1 th cell measurement result includes the target cell participating in the terminal stationary state decision last time, and the target reference signals in the M beam directions of the target cell, and the cell measurement result of the target cell is selected from the candidate cell measurement results, that is, when the last decision result is in the stationary state, the target cell participating in the decision process and the target reference signals in the M beam directions are set unchanged.
Step 802C, selecting a cell measurement result of the target cell from the candidate cell measurement results according to the target cell screening rule under the condition that the historical terminal state indicates that the terminal is in a mobile state.
When the last decision result indicates that the terminal is in a mobile state, the terminal is more likely to be in a mobile state during the cell measurement, and only the target cells involved in the decision need to be determined again, which corresponds to a possible implementation manner, in a case that the terminal state indicates that the terminal is in a mobile state, the target reference signals corresponding to the target cells and the corresponding cell measurement results thereof can be selected again from the candidate cell measurement results based on the target cell screening Gui Ce.
It should be noted that, taking at least two cell measurement results including the i-1 th cell measurement result and the i-1 th cell measurement result as an example, when i=2, the corresponding i-1=1 indicates that it is necessary to determine whether the terminal is in a stationary state according to the first cell measurement result and the second cell measurement result, that is, the terminal stationary decision module is started for the first time (initial start), and when the terminal stationary decision module is started initially, it is necessary to reselect or initially select the target cell of the current terminal stationary decision, in order to make the subsequent step jump to the step of selecting the target cell based on the target cell screening rule, when i=2, the terminal is in a moving state during the period from the i-2 th cell measurement to the i-1 th cell measurement, that is, when i=2, the decision result of the last terminal stationary state by default is in a moving state, after the second cell measurement is completed, it is necessary to select a beam from the first cell and the second cell corresponding to the target cell of the second measurement result, and the target cell of each reference cell corresponding to the reference cell in the measurement result M is selected.
Optionally, in the case that the serving cell in which the terminal resides is changed, for example, when the terminal performs cell reselection and cell handover, the terminal is in a mobile state, and it is also necessary to reselect a target cell and a target reference signal from the candidate cell measurement results and the corresponding cell measurement results according to the target cell screening rule.
Optionally, when the terminal decision module of the present application is started for the first time, the terminal of the last terminal decision result may be set to be in a non-stationary state (moving state).
Fig. 9 is a schematic diagram illustrating a process flow of a terminal decision module according to an exemplary embodiment of the present application. 901, measuring a serving cell and a neighbor cell, when obtaining measurement results of the terminal on the serving cell and the neighbor cell, entering a step 902, obtaining whether the last Beam monitoring decision position is static, namely obtaining whether the last decision result of the terminal indicates that the terminal is in a static state, if so (in the static state), entering a step 905, directly executing monitoring and decision of each Beam measurement result of each cell without reselecting a target cell, and outputting decision results of whether the terminal is static or moving, otherwise, if the last decision result indicates that the terminal is not in the static state (in the moving state), entering a step 903, reselecting the target cell, namely executing TopN monitoring cell selections, and entering a step 904, reselecting target reference signals in the target cell, namely executing Beam selections of each TopMi of the monitoring cells.
Optionally, when selecting the target cell from the candidate cells, the number and the signal strength needs need to be considered, and in an illustrative example, the step 802C may include the following steps 802C1 to 802C4.
Step 802C1, determining the maximum signal strength corresponding to each candidate cell from the candidate cell measurement results.
Since the NR cells correspond to the reference signals in different beam directions, and the positions of the terminal in the NR cells are different, the signal strengths of the reference signals in the different beam directions are different, and only the signal strength of the reference signal in the beam direction opposite to the terminal is the largest, in order to more accurately compare the signal qualities of the candidate cells, in one possible implementation manner, the reference signal with the strongest signal strength in the candidate cells is adopted to represent the candidate cell, that is, the maximum signal strength corresponding to each candidate cell is determined from the measurement result of the candidate cell, so that the cell signal quality is screened based on the maximum signal strength.
And step 802C2, sorting the candidate cells according to the maximum signal intensity from high to low to obtain a candidate cell sequence.
In order to select a candidate cell with better signal quality, the candidate cells can be ordered according to the maximum signal strength to obtain a candidate cell sequence, and the selection of the target cell is further performed based on the candidate cell sequence.
Alternatively, when the candidate cells are ranked, the candidate cell sequences may be obtained by ranking from high to low according to the maximum signal strength, or may be obtained by ranking from low to high according to the maximum signal strength, which is not limited in this embodiment.
Step 802C3, determining the first N candidate cells in the candidate cell sequence as target cells, where N is a positive integer.
In order to avoid that the number of the selected target cells is too large to affect the decision efficiency of the terminal, in a possible implementation manner, the number of the target cells is set to be N, and only the first N candidate cells with stronger signal strength are selected from the candidate cell sequences to be used as the target cells for the subsequent decision of the terminal in the static state.
The specific value of N may be set by a developer and a service person according to requirements, for example, N may be 1,3,5, etc., and the more target cells participating in the decision of the terminal static state, the more reliable the result of outputting the terminal static state.
In order to further improve the signal quality of the selected target cell, in a possible implementation manner, the target cell may be selected from the candidate cells based on the signal-to-noise ratio and the signal strength, when evaluating the signal quality of the candidate cells, not only considering the signal strength (signal receiving power) but also considering the signal-to-noise ratio.
Alternatively, when the target cell is selected from the candidate cell sequence in consideration of the signal-to-noise ratio, the first N candidate cells in the candidate cell sequence with the signal-to-noise ratio greater than the first signal-to-noise ratio threshold may be determined as the target cell. For example, if the candidate cell sequence is ordered from high to low according to the maximum signal strength, when the 1 st candidate cell is selected, comparing the relation between the signal to noise ratio of the candidate cell and the first signal to noise ratio threshold, if the signal to noise ratio of the candidate cell is greater than the first signal to noise ratio threshold, determining the candidate cell as a target cell, and continuing to select the next candidate cell, otherwise, if the signal to noise ratio of the candidate cell is less than the first signal to noise ratio threshold, continuing to select the next candidate cell.
Optionally, in order to avoid that the selected target cells are all located in the same direction of the terminal, so as to ensure that the selected target cells are as reasonable as possible in plane geometry and as dispersed in different directions of the terminal as much as possible, instead of being gathered in one direction, in a possible implementation manner, when the target cells are selected based on signal strength and signal to noise ratio, the number of co-frequency cells needs to be reduced as much as possible in consideration of frequency points of each candidate cell.
In an exemplary embodiment, 802C3 may further include the following steps one to four.
Step one, selecting the first N candidate cells with the signal to noise ratio larger than a first signal to noise ratio threshold value from the candidate cell sequences.
In one possible implementation, first, based on the signal-to-noise ratio and the first signal-to-noise ratio threshold, the first N candidate cells with signal-to-noise ratios greater than the first signal-to-noise ratio threshold are selected from the candidate cell sequence, where each of the first N candidate cells is a cell with better signal quality.
Step two, determining the number of cells belonging to the same-frequency cell in the first N candidate cells.
In order to ensure the planar geometry between the selected target cells, the number of co-channel cells in the target cells needs to be limited, so in one possible implementation, the number of cells belonging to the co-channel cells in the first N candidate cells may be determined to determine whether the number of co-channel cells in the first N candidate cells is greater.
And step three, under the condition that the number of the cells is smaller than a number threshold value, determining the first N candidate cells as target cells.
In one possible implementation manner, by comparing the relation between the number of cells of the same frequency cells and the number threshold value, whether the first N candidate cells are directly determined as target cells can be determined, if the number of cells is smaller than the number threshold value, the number of cells in the same direction in the first N candidate cells is small, the situation that candidate cells in different directions exist in the first N candidate cells is guaranteed, and if the number of cells is smaller than the number threshold value, the first N candidate cells are directly determined as target cells.
Wherein the number threshold may be 2.
And step four, determining a target cell from the first N candidate cells based on the number threshold and the same-frequency cells under the condition that the number of cells is larger than the number threshold, wherein the number of the same-frequency cells in the target cell is lower than the number threshold.
Optionally, if the number of cells is greater than the number threshold, the number of cells in the same direction in the first N candidate cells is greater, and in order to ensure the plane geometry of the selected cells, redundant common-frequency cells need to be removed from the first N candidate cells. Specifically, the target cell may be determined from the first N candidate cells according to the number threshold and the common-frequency cells, so as to ensure that the number of common-frequency cells in the target cell is lower than the number threshold.
Optionally, when removing the redundant co-frequency cells, the candidate cells to be removed may be selected based on the signal strength and the signal-to-noise ratio, for example, the candidate cells with lower signal strength and/or lower signal-to-noise ratio in the co-frequency cells are removed.
Optionally, in other possible embodiments, in the process of screening the target cell from the candidate cell sequence, the screening may also be performed according to the signal-to-noise ratio and the number threshold of the same-frequency cells at the same time, for example, if the number threshold is 2, the first candidate cell, the second candidate cell and the third candidate cell in the candidate cell sequence all satisfy that the signal-to-noise ratio is greater than the first signal-to-noise ratio threshold, but the three candidate cells belong to the same-frequency cell, then the redundant candidate cell may be removed from the three candidate cells, and then the fourth candidate cell selection process is continued, and so on, until N candidate cells are screened out, and the N candidate cells are determined to be the target cell.
As shown in fig. 10, a schematic diagram of characteristics of a terminal for measuring beams of N cells according to an exemplary embodiment of the present application is shown. As shown in fig. 10, the selected N cells are a serving cell, a neighboring cell 1 and a neighboring cell 2 (n=3) of the terminal, and the three cells have triangular plane geometry characteristics, and if it is detected that the signal strength does not change twice continuously, it can be determined that the current position of the terminal is fixed and in a stationary state.
Step 802C4, based on the target cell, obtaining a cell measurement result from the candidate cell measurement results.
In one possible implementation manner, after the target cell involved in the decision of the terminal in the stationary state is screened, the measurement result corresponding to the target cell can be selected from the candidate cell measurement results, and the measurement result is determined as a cell measurement result.
Since the target cell corresponds to reference signals in different beam directions, if the reference signals in all beam directions are selected to participate in the terminal static state judgment, under the condition of more beam directions, for example, when l=64, the judgment process is more complicated and complex, and the reference signals with poor signal strength are introduced in the judgment process and influence the judgment accuracy, in order to further improve the judgment efficiency and the judgment accuracy, in a possible implementation manner, a specific number of target reference signals required to participate in the subsequent judgment process can be selected from the reference signals in each beam direction corresponding to the target cell. In one illustrative example, step 802C4 may include the following steps five and six.
And fifthly, selecting M target reference signals in different beam directions from the reference signals in at least two different beam directions corresponding to the target cell based on the measurement result of the candidate cell, wherein M is an integer greater than 1 and less than or equal to a beam quantity threshold, and the beam quantity threshold is determined by the frequency range of the cell frequency point corresponding to the target cell.
When selecting the target reference signals required by participating in the subsequent decision process from the target cell, the requirements of decision efficiency and decision accuracy are integrated, and in a possible implementation manner, two factors of the number of the selected reference signals and the reference signal strength can be comprehensively considered, and based on the measurement result of the candidate cell, the target reference signals in M different beam directions are selected from the reference signals in different beam directions corresponding to the target cell.
Similar to the above screening of the target cell, when the target reference signal is screened, the reference signals may be first sorted according to the signal strength of the reference signals from high to low, so as to obtain a reference signal sequence, and then the first M reference signals with signal to noise ratio greater than the second signal to noise ratio threshold value are selected from the reference signal sequence, and are determined as the target reference signals in M different beam directions.
The value of M is necessarily equal to or less than the number of beams owned by the target cell, and for example, if L is 4, the value of M may be an integer equal to or less than 4, and if L is 8, the value of M may be an integer equal to or less than 8.
It should be noted that, since the first snr threshold is determined based on the maximum signal strength of each cell, and the signal strengths of other beams in each cell are smaller than the maximum signal strength, when the second snr threshold is set, the first snr threshold is generally set to be greater than the second snr threshold. Illustratively, if the first signal-to-noise ratio threshold is-5 db, the second signal-to-noise ratio threshold may be-8 db.
And step six, obtaining cell measurement results of target reference signals in M different beam directions corresponding to the target cell from the candidate cell measurement results.
In one possible implementation manner, after N target cells are selected from the plurality of candidate cells and each target cell selects the target reference signals corresponding to M beam directions, a cell measurement result corresponding to the target cell may be obtained from the candidate cell measurement results based on the target cell and the target reference signals.
Step 803, determining a target measurement difference value corresponding to the target cell based on at least two cell measurement results of the target cell.
Step 804, determining that the terminal is in a stationary state during at least two cell measurements in case the target measurement difference is below a target measurement threshold.
The implementation manners of step 803 and step 804 may refer to the above embodiments, and this embodiment is not described herein.
In this embodiment, the target cell participating in the terminal stillness state determination and the corresponding target reference signal thereof may be selected from the candidate cells according to the target cell screening rule, so that the target cell and the target reference signal meet the requirements of signal quality requirements, geometric plane characteristics and the like, thereby improving the signal quality of the target cell participating in the terminal stillness state determination, and further improving the accuracy of terminal stillness state determination.
Referring to fig. 11, a schematic diagram of a complete decision flow shown in an exemplary embodiment of the present application is shown. The decision process comprises the following steps:
step 1101 checks if the SNR of the measured Beam crosses a threshold.
Step 1102, take the last filtering result (including time position and signal strength) of the Beam and compare with the current measurement result of Beam.
In step 1103, it is detected whether the time position deviation is within a preset threshold.
In step 1104, it is detected whether the signal strength difference is within a preset threshold.
Step 1105, filtering the current measurement result and the last filtering result, and storing the final filtering value.
Step 1106, whether Mi beams are all complete.
Step 1107, taking the filter values of all beams of the measurement cell, and comparing whether the difference value of RSRP between TopMi beams and the difference value of the stored historical filter values are within a preset threshold.
At step 1108, the difference in RSRP between the topmi beams is filtered and saved.
Step 1109, it is determined that each Beam of the cell has not changed.
Step 1110, it is checked whether the cells of TopN all decide to be completed.
And step 1111, judging the static state of the terminal position.
Step 1112, take the next Beam measurement of the cell.
Step 1113, take each Beam measurement of the next cell.
Step 1114, the terminal position movement is determined.

In a possible application scenario, when it is determined that the terminal is in a stationary state for a long period of time by the terminal stationary state determining method shown in the above embodiment, the terminal may be triggered to use some low power policies, so as to further reduce the final power consumption. Taking the low power consumption strategy as an example, when the state determination result in the target time period indicates that the terminal is always in the static state, the low power consumption cell measurement strategy can be switched to be used, and the low power consumption cell measurement strategy can be a strategy related to the cell measurement frequency, for example, the cell measurement frequency is reduced (regulated) so that the regulated cell measurement frequency is lower than the cell measurement frequency before regulation, the cell measurement frequency of the terminal in the static state is reduced, and therefore the cell measurement power consumption of the terminal in the static state is reduced. Wherein the target period of time may be 1h.
Optionally, in other possible embodiments, when the state determination results in the continuous period of time indicate that the terminal is in a moving state, it indicates that the terminal may be in a continuous moving state, and in order to enable the terminal to switch to a cell with better quality in time, the terminal may be triggered to use a cell measurement policy with high power consumption, for example, to increase the cell measurement frequency and so on.
The embodiment is only exemplified by taking the low power consumption policy as an example of the cell measurement policy, and in other possible implementations, the low power consumption policy may also be a policy that the terminal positioning policy (when the terminal is in a static state, the frequency of sending and receiving the positioning signal by the terminal may also be reduced to reduce the positioning power consumption) is equal to the policy related to the location where the terminal is located.
