Description

Pilot frequency measurement method and related equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a pilot frequency measurement method and related devices.

Background

In the prior art, the 3GPP (3rd Generation Partnership Project) standard specifies that a threshold for initiating intra-System or inter-System inter-frequency measurement (i.e., event a2) is only one for each cell, for a System on Chip (SoC) of a mobile terminal of a mobile network such as 4G or 5G; however, as the kinds of APPs (applications) of the mobile terminal become more and more abundant, it is difficult for the wireless network optimizer of the telecom operator or the mobile network equipment provider to determine a suitable value to meet the requirements of various APPs on the wireless channel carrying capacity. For example: because the threshold of the inter-frequency measurement is a cell-level parameter, a telecom operator usually conserves the configuration of the threshold, and assumes that the configuration of the threshold of the inter-frequency measurement is relatively low, when the Quality of a radio channel cannot meet the Quality of Experience (QoE) of part of APPs, the SoC of the mobile terminal cannot start the inter-frequency measurement in time, so as to find out that the inter-frequency adjacent cell with better channel Quality is switched, thereby meeting the user Experience. Therefore, there is a need to solve the above technical problems.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

It should be understood that the terms "first," "second," and the like in the description and claims of this application and in the drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by the person skilled in the art that the described embodiments of the invention can be combined with other embodiments.

It should be understood that a terminal in the embodiments of the present application may refer to various forms of user equipment (user equipment), an access terminal, a subscriber unit, a subscriber station, a mobile station (mobile station, MS), a remote station, a remote terminal, a mobile device, a user terminal, a terminal equipment (terminal equipment), a wireless inter-frequency measurement device, a user agent, or a user equipment. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with a Wireless communication function, a computing device or other processing devices connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5G Network, or a terminal device in a Public Land Mobile Network (PLMN) for future evolution, and the like, which are not limited in this embodiment.

A Base Station (BS) in the embodiment of the present application, which may also be referred to as a base station device or an access network device, is a device deployed in a Radio Access Network (RAN) to provide a wireless communication function. For example, a device providing a base station function in a 4G network includes an evolved node B (evolved NodeB, eNB), and in a Wireless Local Area Network (WLAN), the device providing the base station function is an Access Point (AP), a device gNB providing the base station function in a 5G New Radio (NR), and a node B (ng-eNB) continuing to evolve, where the gNB and the terminal communicate using an NR technology, the ng-eNB and the terminal communicate using an E-utra (evolved Universal Radio access) technology, and both the gNB and the ng-eNB may be connected to the 5G core network. The base station in the embodiment of the present application also includes a device or the like that provides a function of the base station in a future new communication system.

In the prior art, the measurement is divided into Intra-frequency measurement (Intra-frequency measurement) and inter-frequency measurement (inter-frequency measurement). The co-frequency measurement means that a serving cell where the terminal is currently located and a target cell to be measured are on the same carrier frequency point (central frequency point). The pilot frequency measurement means that the serving cell and the target cell where the terminal is currently located are not on one carrier frequency point. If the terminal needs to perform different-frequency measurement (including different-mode measurement), one of the simple ways is to install 2 radio frequency receivers in the terminal device to measure the frequency point of the serving cell and the frequency point of the target cell respectively, but this would bring about the problems of cost increase and mutual interference between different frequency points. Therefore, 3GPP proposes a method for measuring GAP (measurement GAP), that is, a part of time (i.e., GAP time measurement) is reserved, during this time, the terminal will not send and receive any data, and the receiver tunes to the frequency point of the target cell to measure the inter-frequency, and then switches to the current serving cell after the GAP time is over.

However, because the threshold configuration of the pilot frequency measurement is low, when the quality of the wireless channel cannot meet the experience quality of part of APPs, the SoC of the mobile terminal cannot start the pilot frequency measurement in time, so as to find out that the pilot frequency neighboring cell with better channel quality is switched, and further meet the user experience, resulting in lower experience quality of the application program. Therefore, the embodiment of the present application provides a new pilot frequency measurement method, which can effectively solve the above technical problems. The method and the device have the advantages that the different-frequency measurement control of the terminal request is carried out according to the wireless channel performance parameter conditions corresponding to different application programs, the wireless channel performance requirements of different application programs can be met, the experience quality of the application programs is guaranteed, and the use experience of users on the application programs is improved.

The pilot frequency measurement method in the embodiment of the present application may be applied to a communication system composed of a base station and a terminal, and the pilot frequency measurement method is specifically described below by taking a terminal side as an example. Referring to fig. 1 and fig. 2, fig. 1 is a schematic flowchart of an inter-frequency measurement method according to an embodiment of the present invention, and fig. 2 is a schematic interactive flowchart of the inter-frequency measurement method according to the embodiment of the present invention; the pilot frequency measurement method is applied to a terminal, and specifically comprises the following steps:

step 101, after a terminal accesses a service cell and enters a connection state, the terminal acquires a wireless channel performance parameter of the service cell according to a first period; acquiring a wireless channel quality parameter of a first pilot frequency adjacent cell of the service cell according to a second period, wherein the number of the first pilot frequency adjacent cells is N;

in particular, the radio channel performance parameter is used to characterize the quality of the radio channel performance of the serving cell. The service cell and the first pilot frequency adjacent cell use different radio frequency carrier frequencies. The specific values of the first period and the second period may be set according to actual needs, and are not particularly limited. Similarly, the number N of the first pilot frequency neighboring cells may be set according to actual needs, and measurement may be started on all or part of pilot frequency points of the serving cell (i.e., the first pilot frequency neighboring cells), where N is 3, for example. In particular, the first inter-frequency neighbor may be an intra-system and/or inter-system inter-frequency neighbor.

Generally, cellular wireless network frequencies include 700MHz, 900MHz, 1800MHz, F + a band, E band, 2.6G band, 4.9G band, etc., where 700MHz-900MHz is considered as low frequency, 1800MHz-2.6G band is considered as medium frequency, and 4.9G band is high frequency. Assuming that the number of the first pilot frequency neighboring cells is 3, taking the terminal having the 4G and 5G communication capabilities as an example, assuming that the serving cell accessed by the current terminal is a 2.6GHz band of the china mobile 5G, the first pilot frequency neighboring cells in the system are other bands belonging to the same 5G, such as 700MHZ, 4.9G band, and the like; and the first inter-system pilot frequency adjacent cell is a frequency band belonging to 4G, such as 900MHz, 1800MHz, F + a frequency band and E frequency band, and if one of the low frequency, the intermediate frequency and the high frequency is respectively selected as the first pilot frequency adjacent cell, the 900MHz, 1800MHz and 4.9G frequency band can be selected as the first pilot frequency adjacent cell.

After the terminal 201 accesses the serving cell and completes RRC connection reconfiguration, i.e., enters a connected state, the terminal starts to acquire the radio channel performance parameters corresponding to the serving cell according to a first period, and acquires the radio channel quality parameters of each first inter-frequency neighboring cell according to a second period.

Step 102, when the terminal determines that the wireless channel performance parameter meets a first condition of a first application program of the terminal, a first measurement report for requesting pilot frequency measurement is sent to a service base station, wherein the first condition is a wireless channel performance parameter condition;

specifically, the first condition corresponding to the first application program may be set according to the requirement of the application program itself, and is not particularly limited; specifically, when there are more than two types of radio channel performance parameters, the first condition is set to correspond to one condition for each type of radio channel performance parameter. For the radio channel performance parameter of the serving cell obtained each time in step 101, the terminal 201 determines whether the first condition is satisfied according to the radio channel performance parameter of the serving cell and the first condition. When the terminal 201 determines that the radio channel performance parameter of the serving cell satisfies the first condition, a first measurement report is sent to the serving base station 202 to request inter-frequency measurement, i.e., the event type of the first measurement report is a 2.

103, the terminal receives pilot frequency adjacent cell measurement configuration information sent by the service base station in response to the first measurement report;

specifically, the serving base station 202 responds to the first measurement report, and issues the inter-frequency neighbor measurement configuration information to the terminal 201, so that the terminal 201 performs the inter-frequency neighbor measurement (because the terminal 201 has performed the inter-frequency measurement in step 101, the inter-frequency neighbor measurement referred to herein is not actually performed, but the terminal 201 directly determines whether to send the second measurement report according to the intersection condition of the first inter-frequency neighbor and the second inter-frequency neighbor, that is, the terminal does not start GAP measurement, so as to ensure the service quality of the terminal). The pilot frequency neighboring cell measurement configuration information is used to indicate a pilot frequency neighboring cell for the terminal 201 to measure, that is, to indicate a second pilot frequency neighboring cell, where the number of the second pilot frequency neighboring cells is M, and the specific number may be set according to actual needs; and the service cell and the second pilot frequency adjacent cell use different radio frequency carrier frequencies.

And step 104, when the terminal determines that the N first pilot frequency adjacent cells and the second pilot frequency adjacent cells configured by the pilot frequency adjacent cell measurement configuration information have an intersection adjacent cell, sending a second measurement report to the service base station, wherein the second measurement report comprises the quality parameters of the wireless channel of the intersection adjacent cell.

Specifically, when the terminal 201 determines that an intersection neighbor exists between N first inter-frequency neighbors and M second inter-frequency neighbors, the terminal sends a second measurement report to the serving base station 202, where the second measurement report includes radio channel quality parameters of the intersection neighbor, and when there are more than two intersection neighbors, the second measurement report includes radio channel quality parameters of the intersection neighbor. And when the terminal determines that the N first pilot frequency adjacent cells and the M second pilot frequency adjacent cells do not have the intersection adjacent cell, sending a third measurement report to the service base station, wherein the third measurement report is used for applying for stopping pilot frequency measurement, namely the event type is A1.

The embodiment of the application provides a new mechanism for starting pilot frequency measurement and a method for sending a pilot frequency measurement report, pilot frequency measurement is started in advance, whether pilot frequency measurement is required or not is controlled according to requirements of an application program on wireless channel performance parameters, the requirements of different application programs on wireless channel performance can be met, when pilot frequency switching is required, a terminal can rapidly apply for pilot frequency switching in a system or between systems to a base station, the experience quality of the application program running on the terminal is guaranteed, and the use experience of a user on the application program is further improved.

By using the pilot frequency measurement method of the embodiment of the application, the user experience can be guaranteed for the user of the application program; for a telecom operator, the pilot frequency measurement starting threshold (event a2) configuration (i.e. the first condition is customized for an application) can be optimized based on the experience quality of the application, and personalized experience guarantee is provided for different applications. And for operators, wireless networks can be optimized, such as configuring a2 threshold based on the experience quality of an application program, so that the ARPU value (average income per user) is improved by centering on the user experience. In addition, for an internet company developing the application program, the user experience can be improved, and the user viscosity can be increased.

Particularly, the pilot frequency measurement method can change the original pilot frequency measurement process to the minimum extent.

In the communication field, a cell selection and cell reselection decider is a terminal, a cell handover decider is a base station, and only the base station has the right to decide whether a cell can be handed over and to which target cell. This is because the base station is the owner and the distributor of all air interface radio resources, and only they have the right to allocate radio resources to the terminal. Therefore, in this embodiment, after the serving base station receives the second measurement report, the serving base station may determine whether the terminal performs intra-system or inter-system inter-frequency handover according to the content of the second measurement report. When the service base station refuses the request of inter-system or intra-system pilot frequency switching of the terminal, the terminal stops the process. Referring to fig. 2, when the serving base station determines that the inter-frequency handover request of the terminal can be accepted according to the actual situation, the serving base station issues an inter-frequency neighbor handover instruction to the terminal; so that the terminal receives the pilot frequency adjacent cell switching instruction and responds to the pilot frequency adjacent cell switching instruction to carry out pilot frequency adjacent cell switching. The pilot frequency adjacent cell switching instruction indicates which pilot frequency adjacent cell the terminal is switched to from the current service cell.

In some possible embodiments, for step 101, the "accessing a serving cell" condition includes that the terminal initially accesses the network after being powered on, initially accesses a serving cell, or the terminal just switches from a previous cell to a new cell. In addition, the terminal itself may determine, by using an existing obtaining method, which of the inter-frequency neighboring cells that can be selected as the first inter-frequency neighboring cell corresponding to the location where the terminal is located is, for example, the obtaining method may be: SIB (System Information Block, SIB) messages can be received through background search, the SIB messages are decoded, and then blind detection is performed on the decoded data to obtain Information of the pilot frequency adjacent cells.

Further, the frequency point of the first pilot frequency adjacent cell to be measured is limited by the industrial capability, and in order to ensure the accuracy of the pilot frequency measurement result, one frequency point can be selected from the low, medium and high frequency bands of the 4G communication system and the 5G communication system, taking the china mobile as an example: the 5G communication system can select: 700M, 2.6G and 4.9G are taken as frequency points of the first pilot frequency adjacent cell; and the 4G communication system may choose to: and 1800MHz is used as the frequency point of the first pilot frequency adjacent region.

In some possible embodiments, in step 101, radio channel performance parameters of a serving cell are obtained according to a first cycle; and acquiring a radio channel quality parameter of a first pilot frequency neighboring cell of the serving cell according to a second period, specifically comprising:

acquiring wireless channel performance parameters of a serving cell according to a first period, and storing a first number of wireless channel performance parameters in a first-in first-out mode; the specific value of the first number m may be determined according to actual needs, and a first-in first-out method is used to store data, so as to ensure that m newly measured and stored radio channel performance parameters are used each time to determine the first condition in step 102. Assuming that m wireless channel performance parameters are stored at present, when a new acquisition period comes, the stored first record data is discarded, and new record data is stored.

And/or the presence of a gas in the gas,

and acquiring the wireless channel quality parameters of the N first pilot frequency adjacent cells according to a second period, and storing a second number of wireless channel performance parameters in a first-in first-out mode. Similarly, the specific value of the second number n may be determined according to actual needs, and a first-in first-out method is used to store data, so as to ensure that the latest measured and stored n radio channel quality parameters are used to perform data processing each time (for example, the second measurement report in the determining step 104 carries the radio channel quality parameters of the intersection neighboring cell). Assuming that n wireless channel quality parameters are stored at present, when a new acquisition period comes, the stored first recorded data is discarded, and new recorded data is stored.

The radio channel performance parameter includes at least one of a bandwidth B, a user plane transmission delay (Round-Trip Time, RTT) D, jitter J, and a packet loss rate L. And/or the wireless Channel Quality parameter includes at least one of Reference Signal Received Power (RSRP) of a Cell Reference Signal (CRS), Reference Signal received power (CSI-RS) of a Channel state information Reference Signal (CSI-RS), Reference Signal Received Power (RSRP) of a Synchronization Signal Block (SSB), Reference Signal Received Quality (RSRQ) of a Cell Reference Signal, and Signal to Interference plus Noise Ratio (SINR).

For example, for a 4G communication system, the correspondingly acquired radio channel quality parameter may be at least one of CRS RSRP, RSRQ, and SINR. And for a 5G communication system, the wireless channel quality parameter may be at least one of SSB RSRP, RSRQ, SINR, CSI-RS RSRP.

For another example, assuming that the radio channel performance parameters are bandwidth B, user plane transmission delay D, jitter J and packet loss rate L, the terminal monitors and records the radio channel performance parameters according to a first period Δ 1, where the number of records is m, and during actual recording, the terminal records the radio channel performance parameters in the uplink and downlink directions respectively, that is, records B ^u 、B ^d 、D ^u 、D ^d 、J ^u 、J ^d 、L ^u 、L ^d Wherein u represents an uplink and d represents a downlink.

For another example, after the terminal determines the specific frequency of the first inter-frequency neighboring cell to be acquired, the terminal acquires the radio channel quality parameters corresponding to the N first inter-frequency neighboring cells at the second period Δ 2, where when the first inter-frequency neighboring cell belongs to the 4G communication system, at least one of CRS RSRP, RSRQ, and SINR may be acquired as the radio channel quality parameter, and when the first inter-frequency neighboring cell belongs to the 5G communication system, the corresponding radio channel quality parameter may be at least one of SSB RSRP, RSRQ, SINR, and CSI-RS RSRP.

In some possible embodiments, in step 102, the first condition of the first application includes a first wireless channel performance parameter condition and a second wireless channel performance parameter condition, the first wireless channel performance parameter condition includes a first threshold value of various wireless channel performance parameters, and the second wireless channel performance parameter condition includes a second threshold value of various wireless channel performance parameters; when the radio channel performance parameter of the serving cell is one, two or more first thresholds (one radio channel performance parameter corresponds to two types of data, i.e., uplink and downlink) and two or more second thresholds need to be set correspondingly. When there are two or more types of radio channel performance parameters of the serving cell, it is necessary to set four or more first thresholds and four or more second thresholds, respectively.

Further, determining that the wireless channel performance parameter satisfies a first condition of a first application of the terminal includes:

determining whether the current wireless channel performance parameter of the serving cell meets a first wireless channel performance parameter condition;

when the first wireless channel performance parameter condition is determined to be met, whether the first average value of the current first number of wireless channel performance parameters of the serving cell meets the second wireless channel performance parameter condition or not is determined, and when the second wireless channel performance parameter condition is met, the wireless channel performance parameters of the serving cell meet the first condition is determined.

When the wireless channel performance parameter of the serving cell is assumed to be one type of parameter, when the wireless channel performance parameter of the parameter in the uplink direction and/or the downlink direction is less than or equal to a corresponding first threshold value, the wireless channel performance parameter of the serving cell is judged to meet the first wireless channel performance parameter condition, and the judgment of the second wireless channel performance parameter condition can be entered. For example, refer to Table 1, wherein the radio channel performance parameters of the serving cellThe bandwidth B corresponds to the bandwidth B ^u 、B ^d Two kinds of data, correspondingly, the first threshold value corresponding to the bandwidth data in the uplink direction is B _b ^u The first threshold corresponding to the bandwidth data in the downlink direction is B _b ^d 。

TABLE 1

When the radio channel performance parameter of the serving cell is more than two parameters, when at least one of the more than two parameters satisfies that the parameter in the uplink direction and/or the parameter in the downlink direction is less than or equal to the corresponding first threshold, it may be determined that the radio channel performance parameter of the serving cell satisfies the first radio channel performance parameter condition, and the determination of the second radio channel performance parameter condition may be entered. Otherwise, the service cell is judged not to meet the first wireless channel performance parameter condition, and the judging process is stopped.

In addition, when the radio channel performance parameter of the serving cell meets the first radio channel performance parameter condition, then obtaining current m radio channel performance parameters of the serving cell to calculate a first average value of the current m radio channel performance parameters, wherein when the radio channel performance parameter of the serving cell is one, the corresponding two first average values of two data in an uplink direction and a downlink direction are correspondingly provided, and the corresponding two first average values are also correspondingly provided with two second threshold values; when there are more than two wireless channel performance parameters, correspondingly, there are more than four first average values of two data in the uplink direction and the downlink direction, and more than four second threshold values need to be correspondingly set. Then, when all the first average values corresponding to the serving cell satisfy the second threshold or less, it may be determined that the serving cell satisfies the second condition for the performance parameter of the radio channel, that is, it may be determined that the performance parameter of the radio channel of the serving cell satisfies the first condition.

For example, assuming that the performance parameters of the wireless channel of the serving cell are bandwidth B, user plane transmission delay D, jitter J, and packet loss rate L, the following 8 first average values are obtained:

B _ave ^u ＝Σ ^m _x＝1 (B _m ^u )/m，B _ave ^d ＝Σ ^m _x＝1 (B _m ^d )/m，

D _ave ^u ＝Σ ^m _x＝1 (D _m ^u )/m，D _ave ^d ＝Σ ^m _x＝1 (D _m ^d )/m，

J _ave ^u ＝Σ ^m _x＝1 (J _m ^u )/m，J _ave ^d ＝Σ ^m _x＝1 (J _m ^d )/m，

L _ave ^u ＝Σ ^m _x＝1 (L _m ^u )/m，L _ave ^d ＝Σ ^m _x＝1 (L _m ^d )/m。

only the following 8 conditions are simultaneously satisfied:

B _ave ^d ≤B _b ^d *△3；

B _ave ^u ≤B _b ^u *△4；

D _ave ^u ≤D _b ^u *△5；

D _ave ^d ≤D _b ^d *△6；

J _ave ^u ≤J _b ^u *△7；

J _ave ^d ≤J _b ^d *△8；

L _ave ^u ≤L _b ^u *△9；

L _ave ^d ≤L _b ^d *△10。

it may be determined that the serving cell satisfies the second radio channel performance parameter, i.e., the radio channel performance parameter of the serving cell at the time satisfies the first condition. The second threshold may be related to the first threshold, that is, the corresponding second threshold is determined according to the first threshold and a preset scaling factor (e.g., Δ 3, Δ4, … … Δ 10 described above), where the preset scaling factor may be 15%, 20%, etc., and the preset scaling factors corresponding to the first thresholds for different wireless channel performance parameters may be the same or different. The second threshold may be set according to actual conditions without depending on the first threshold, and is not particularly limited.

When the terminal determines that the wireless channel performance parameter of the serving cell meets the first condition, the terminal sends a first measurement report of an event A2 to the serving base station to apply for inter-frequency measurement.

In some possible embodiments, in step 103, the receiving, by the terminal, the pilot frequency neighboring cell measurement configuration information sent by the serving base station in response to the first measurement report includes:

and receiving RRC connection reconfiguration information which is sent by the service base station in response to the first measurement report, wherein the RRC connection reconfiguration information is used for indicating the terminal to carry out pilot frequency adjacent cell measurement, and the RRC connection reconfiguration information comprises pilot frequency adjacent cell measurement configuration information.

The RRC connection reconfiguration information may include, in addition to the inter-frequency neighboring cell measurement configuration information used for configuring the second inter-frequency neighboring cell that the terminal needs to measure, at least one of a measurement event of a measurement task and a parameter thereof (report configuration), and a common configuration in a measurement message.

In some possible embodiments, in step 102, the first measurement report may further include an identification of the first application, for example, a parameter name of the identification is osapid or APPID. Therefore, the service base station can know that the first application program has the requirement of modifying the pilot frequency adjacent cells, and when the first pilot frequency adjacent cells and the second pilot frequency adjacent cells have difference sets, the service base station can help an operator to check the pilot frequency adjacent cells which are missed to be matched (namely N first pilot frequency adjacent cells and the difference sets of the M pilot frequency adjacent cells and the second pilot frequency adjacent cells), and provides a method for quickly identifying the capacity requirement of the hotspot regions and the application programs. After obtaining the identifier of the first application program, the serving base station may carry the identifier of the first application program in the RRC connection reconfiguration information, so that the terminal may determine that the RRC connection reconfiguration information is the configuration information of the terminal according to the identifier. Likewise, the second measurement report may also include an identification of the first application.

In some possible embodiments, when the first measurement report further includes the identifier of the first application program, after receiving the first measurement report, the serving base station may cancel the GAP measurement configuration according to the identifier of the first application program, that is, the serving base station does not issue GAP measurement configuration information to the terminal, so as to save network wireless resources and improve the utilization rate of the wireless resources.

In some possible embodiments, the inter-frequency measurement method further includes:

when determining that the current wireless channel performance parameter of a serving cell meets the first wireless channel performance parameter condition, acquiring first position information of a terminal;

when the current first average value of the serving cell meets the second wireless channel performance parameter condition, acquiring second position information of the terminal;

Specifically, when the current radio channel performance parameter of the serving cell meets the first radio channel performance parameter condition, the first position information GNSS of the terminal is acquired ₀ (ii) a And when the current first average value of the serving cell meets the second wireless channel performance parameter condition, acquiring second position information GNSS of the terminal _n And determining the moving speed V-f of the terminal at the moment according to the first position information and the second position information ₁ (GNSS ₀ ，GNSS _n ). The radio channel bearing capacity of the first pilot frequency adjacent cell can be determined according to the moving speed of the terminal, so that the sequencing of the radio channel bearing capacity of the N first pilot frequency adjacent cells is realized.

In some possible embodiments, after sending the first measurement report to the serving base station and before sending the second measurement report to the serving base station, the inter-frequency measurement method further includes:

and determining the wireless channel bearing capacity of the first pilot frequency adjacent cell according to a second average value of the second number of wireless channel quality parameters corresponding to the first pilot frequency adjacent cell, the moving speed and the preset weight of each wireless channel performance parameter.

Specifically, for each first pilot frequency neighboring cell, a corresponding second average value is determined according to n wireless channel quality parameters corresponding to the first pilot frequency neighboring cell (when there are more than two wireless channel instruction parameters, there are two corresponding second average values), and then the wireless channel bearing capacity of the first pilot frequency neighboring cell is determined according to the second average value, the moving speed of the terminal, and the preset weight corresponding to each wireless channel quality parameter by using the existing method for determining the wireless channel bearing capacity. When the quality parameters of the wireless channels of the first pilot frequency adjacent cell are more than two, different preset weights are preset for the quality parameters of the wireless channels, and the sum of the preset weights is one. The specific value of the preset weight of each wireless channel quality parameter can be set according to actual conditions.

Further, in the actual use process, after a certain APP is started, the first threshold of each corresponding wireless channel performance parameter, the preset weight of each wireless channel performance parameter, and each preset proportionality coefficient are transmitted to the terminal.

Specifically, for example, the APP communicates to the terminal the following parameters: (B) _b ^u ，W ₁₁ )&(B _b ^d ，W ₁₂ )，(D _b ^u ，W ₂₁ )&(D _b ^d ，W ₂₂ )，(J _b ^u ，W ₃₁ )&(J _b ^d ，W ₃₂ )，(L _b ^u ，W ₄₁ )&(L _b ^d ，W ₄₂ )。

Wherein, B _b Representative of bandwidth, D _b Representing the user plane transmission delay, J _b Representing jitter, L _b Representing packet loss rate, W _xy Representing the weight of the parameter, the above 4 parameters do not necessarily need to determine a specific value, and if a certain parameter is equal to 0, it means that the parameter is invalid, and the corresponding weight is equal to 0.

Because different APPs have different requirements for various wireless channel performance parameters, it is necessary to set a weight for each wireless channel performance parameter, so as to select a suitable system and a different frequency to provide the APP with the most suitable wireless channel carrying capability in the subsequent different frequency handover, for example:

A. for video telephony: the bandwidth requirement is medium, and the "delay & jitter & packet loss rate" is sensitive, so that the weight correspondingly allocated to the delay & jitter & packet loss rate is large, the mobility is high, and the APP can be preferentially switched from the medium frequency to the high frequency (FDD network).

B. For video streaming: the bandwidth requirement is high (the resolution is 1080P- >2K), namely the weight of bandwidth allocation is large, the time delay is insensitive, and the APP can be preferentially carried by a 4G or 5G medium-high frequency network.

In some possible embodiments, the sending the radio channel quality parameters of the intersection neighboring cell to the serving base station includes:

determining the sequence of the intersection adjacent regions according to the wireless channel bearing capacity of the intersection adjacent regions; and sending the radio channel quality parameters of the intersection adjacent regions which are arranged according to the sequence to the service base station.

After the radio channel bearing capacity of the first pilot frequency adjacent cells is determined, the sequence of the N first pilot frequency adjacent cells can be determined according to the radio channel bearing capacity, and when the radio channel quality parameters of the intersection adjacent cells need to be sent, the sequence of the radio channel quality parameters is determined according to the sequence of the intersection adjacent cells in the sequence. In particular, the radio channel quality parameter of each intersection neighboring cell refers to a current second average value of the intersection neighboring cell.

In some possible embodiments, the second measurement report further includes all or part of the radio channel quality parameters of the first inter-frequency neighboring cells except the intersection neighboring cell among the N first inter-frequency neighboring cells. Further, the second measurement report may further include a Cell identity identifier (PCI) of the current serving Cell of the terminal.

That is, when the N first pilot frequency neighboring cells are all in the M second pilot frequency neighboring cell sets issued by the serving base station, the second measurement report is reported according to an event required by the base station (e.g., an a4 event/a B1 event), where the second measurement report includes the PCI, the frequency point corresponding to the first pilot frequency neighboring cell, and the radio channel quality parameter of the first pilot frequency neighboring cell.

If a part of the N first pilot frequency adjacent cells is not in M second pilot frequency adjacent cell sets issued by the service base station, the terminal reports the quality parameters of the wireless channels including the PCI, the frequency points corresponding to the intersection adjacent cells and the intersection adjacent cells in a second measurement report; in addition, optionally, the frequency points corresponding to the difference set neighbor cells of the N first inter-frequency neighbor cells and the M second inter-frequency neighbor cells and the corresponding radio channel quality parameters may also be reported in the second measurement report, so as to help an operator to find the inter-frequency neighbor cells that are missed in configuration.

And if the N first pilot frequency adjacent cells are not in the M second pilot frequency adjacent cell sets issued by the service base station, the terminal sends a third measurement report (event A1) to the service base station so as to apply the service base station to stop pilot frequency measurement.

Particularly, the pilot frequency measurement method of the embodiment of the invention has a more obvious effect on improving the user experience of the terminal without activating the carrier aggregation. The terminal does not activate the carrier aggregation function during the use of the application program and includes the following scenes:

the wireless network does not support carrier aggregation, for example, the carrier aggregation is not opened by the 5G base station of the chinese telecom operator.

The terminal does not support carrier aggregation.

Although both the terminal and the wireless network support the carrier aggregation function, the carrier aggregation frequency bands between the terminal and the wireless network are not matched.

The pilot frequency measurement method according to the embodiment of the present invention is described below with an actual example, where the parameter name of the identification identifier of the first application is osapid as an example, and the steps executed by the terminal are executed by the SoC in the terminal:

1. in a dense urban area, a mobile terminal such as a mobile phone is taken as an example of a terminal, the mobile terminal is connected to a network (not supporting CA) indoors (such as Sambark), and resides in a China mobile 5G 2.6GHz frequency band, and other frequency bands cover the site at the same time:

A.5G：700MHz，4.9GHz；

B.4G：900/1800/2600Mhz。

2. the SoC of the mobile terminal obtains the inter-system pilot frequency adjacent regions and the intra-system pilot frequency adjacent regions of China mobile in the current region where the terminal is located in an idle state and/or a connection state. And the SoC can use all or part of the obtained pilot frequency adjacent regions as the N first pilot frequency adjacent regions according to the needs. Assuming that the N first pilot frequency adjacent cells are 5G: 700MHz, 4.9GHz, 4G: 1800 MHz.

3. The user opens a video APP on the mobile terminal, the mobile terminal enters a connection state, and the APP immediately transmits first threshold values of various corresponding wireless channel performance parameters (of the APP negotiated before) and preset weights and various preset proportionality coefficients of each wireless channel performance parameter to the SoC of the mobile terminal, for example, bandwidth B in the downlink direction ^d The corresponding preset proportionality coefficient is 15%, and the user plane transmission time delay D in the downlink direction ^d The corresponding preset proportionality coefficient is 10%, and the packet loss rate L in the downlink direction ^d The corresponding predetermined scaling factor is 20%. The preset weight of each wireless channel performance parameter corresponding to the APP is shown in table 2:

TABLE 2

4. The mobile terminal SoC is in accordance with 10ms period, to { B } _m ^d ；D _m ^d ；L _m ^d And (5) monitoring and recording (the recording time is m, discarding the first recorded data and storing new recorded data if the recording time exceeds 5).

5. The SoC of the mobile terminal measures and records the quality parameters of the wireless channels of 3 first inter-frequency neighboring cells (5G: 700MHz, 4.9GHz, 4G: 1800MHz) according to a 20ms period (the number of recording times is n-5, if the number exceeds 5, the first recorded data is discarded, and new recorded data is stored), for example:

the method comprises the steps that inter-frequency adjacent cells (namely 1800MHz) of a 4G system record CRS RSRP, RSRQ and SINR as wireless channel quality parameters; and pilot frequency adjacent cells (namely 700MHz and 4.9GHz) of the 5G system record CSI-RS RSRP, RSRQ, SINR and SSB RSRP as wireless channel quality parameters.

6. During the use of the APP, the radio channel bearer capability cannot meet the requirement of the APP on the first threshold, such as: because the number of users is continuously increased, the network interference is improved, the number of pictures increases, and the number of pictures does not reach the event A2 threshold of the SoC issued by the service base station to the mobile terminal, the SoC of the mobile terminal calculates according to the data monitored and recorded in the step 5:

B _ave ^d ＝Σ ⁵ _x＝1 (B _x ^d )/5，

D _ave ^d ＝Σ ⁵ _x＝1 (D _x ^d )/5，

L _ave ^d ＝Σ ⁵ _x＝1 (L _m ^d )/5。

and records the position GNSS of the terminal at the moment ₀ 。

7. The SoC of the mobile terminal determines whether to report the first measurement report to the serving base station by the following calculation.

If: b _ave ^d ≤B _b ^d 15% or D _ave ^d ≤D _b ^d 10% or L _ave ^d ≤L _b ^d *20％；

Then:

A. the SoC of the mobile terminal sends a Measurement Report message of event a2, i.e. a first Measurement Report, to the serving base station, and the optional parameters are as follows: the OSAppID.

B. Recording GNSS at the time _n And calculating the moving speed V ═ f of the terminal ₁ (GNSS ₀ ，GNSS _n ) Otherwise: go back to step 6.

8. After receiving a first measurement report reported by a terminal, a service base station sends pilot frequency neighboring cell measurement configuration information to the terminal, wherein the pilot frequency neighboring cell measurement configuration information comprises: the measurement frequency point (700MHz, 4.9GHz) of the pilot frequency in the system, that is, the second pilot frequency adjacent region, measurement event a4, optional parameters: the OSAppID.

9. After receiving the pilot frequency adjacent cell measurement configuration information issued by the service base station, the SoC of the mobile terminal calculates the radio channel bearing capacity of each first pilot frequency adjacent cell and sorts the radio channel bearing capacity according to the priority by combining the moving speed of the terminal, the second average value of each radio channel performance parameter and the preset weight of each radio channel performance parameter.

For example, the prioritization results in:

(1) the time delay of 5G 700MHz is low, the indoor coverage quality is good (determined by RSRP), the interference is small (determined by RSRQ and/or SINR), and the terminal is static.

(2) The delay of 4G 1800MHz is low, the indoor coverage quality is medium (determined by RSRP), the interference is large (determined by RSRQ and/or SINR), and the terminal is stationary.

(3) High delay at 5G 4.9GHz (TDD vs FDD), poor indoor coverage quality (determined by RSRP), low interference (determined by RSRQ and/or SINR), and the terminal is stationary.

10. The SoC of the mobile terminal reports the Measurement Report message, i.e. the second Measurement Report, by using the event a4 according to the calculation result in the step 10 and the requirement of the base station, wherein the second Measurement Report includes: a cell identification flag of a serving cell; the frequency bin of the intersection neighborhood (i.e., 700 MHz); a second mean value corresponding to RSRP, RSRQ and SINR; the optional parameters are: the OSAppID. In addition, the frequency point and the second mean value of the remaining first pilot frequency neighboring cells except the intersection neighboring cell in the 3 first pilot frequency neighboring cells may also be added and carried in the second measurement report. And when the intersection neighborhood does not exist, the SoC of the mobile terminal sends a third measurement report to the serving base station (event a1) to apply the serving base station for stopping the inter-frequency measurement.

11. The service base station refuses or accepts the request of inter-system or intra-system pilot frequency switching of the terminal according to the second measurement report, and when the base station refuses the request of inter-system pilot frequency switching, the terminal stops the process; otherwise, the terminal responds to the control of the base station to carry out pilot frequency switching.

Based on the above embodiment of the pilot frequency measurement method using a terminal, an embodiment of the present invention further provides a pilot frequency measurement method using a base station, and referring to fig. 3, fig. 3 is a schematic flow chart of another pilot frequency measurement method provided in the embodiment of the present invention, where the pilot frequency measurement method includes the following steps:

step 301, a base station receives a first measurement report for requesting pilot frequency measurement sent by a terminal, wherein the first measurement report is sent when the terminal accesses a serving cell and enters a connected state, acquires a wireless channel performance parameter of the serving cell according to a first period, and determines that the wireless channel performance parameter meets a first condition of a first application program of the terminal, and the first condition is a wireless channel performance parameter condition; after the terminal is accessed to a service cell and enters a connection state, the terminal also acquires the quality parameters of the wireless channel of a first pilot frequency adjacent cell of the service cell according to a second period, wherein the number of the first pilot frequency adjacent cells is N;
