Description

Method and device for obtaining measured time

technical field

Detailed ways

The specific implementation process of the present invention will be described by way of examples below. Apparently, the embodiments described below are some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Embodiment 1. A method for obtaining measurement time. The process flow of the method is shown in Figure 1a.

S100. The user terminal receives a measurement control message delivered by the network side. The measurement control message here can be that the radio network controller, the evolved base station or the relay station sends the measurement control message to the user terminal, or it can be the operation, management and maintenance (Operations Administration and Maintenance, OAM) through the radio network controller or the evolved The base station sends a measurement control message to the user terminal. The measurement control message may also be sent by other network-side entities, and this embodiment does not limit the name of the specific entity sending the measurement control message.

The function of the measurement control message includes: notifying the UE to perform measurement. The measurement control message may include: measurement trigger condition information, measurement quantity information, report quantity information, measurement result reporting trigger condition information, and the like. In this embodiment, the measurement control message delivered by the network side to the user terminal may include the reference time provided by the network side to the user terminal, or may not include the reference time provided by the network side to the user terminal. This embodiment does not limit the specific message structure of the measurement control message. Preferably, the reference time is not included in the measurement control message, so as to further save air interface resources and reduce signaling overhead.

S101. The user terminal acquires measurement data according to the received measurement control message.

The user terminal performs measurement according to the measurement control message, and obtains corresponding measurement results. The user terminal may directly use the measurement result as the measurement data, or may use the measurement result conforming to the reporting trigger condition information as the measurement data.

S110. The user terminal determines the time interval between the local time when the measurement data is obtained and the local time when the measurement control message is received.

There are many ways for the user terminal to obtain the above time interval. A specific example is: when the user terminal receives the measurement control message sent by the network side, it starts a timer, and when the user terminal obtains the measurement data through measurement, it stores the value of the timer The current timing value, the current timing value is the above-mentioned time interval. The above-mentioned timer may be a timer provided by the network side to the user terminal. A specific example: the measurement control message sent by the network side to the user terminal carries timer information. When the user terminal receives the measurement control message, the measurement control Get the timer information from the message and start the timer. The above-mentioned timer may also be a timer provided by the user terminal itself, that is, when the user terminal receives the measurement control message, it starts the timer to start timing, and acquires the timer value when the measurement data is obtained. This embodiment does not limit the specific implementation manner in which the user terminal obtains the timer. In this embodiment, in order to make the counting value of the timer when the measurement data is obtained as the time interval, preferably, the timer needs to be reset before starting the timer. The resetting only needs to be completed before starting the timer. For example, the timer may be reset when a measurement control message is received, or the timer may be reset after the timer count value is obtained.

Another specific example for the user terminal to obtain the above time interval is: when the user terminal receives the measurement control message sent by the network side, it records the first current local time according to the local clock, and the first current local time is the measurement control message received by the user terminal. The local time at the time of the message. When the user terminal obtains the measurement data, the second current local time is recorded, and the second current local time is the local time when the user terminal obtains the measurement data. The user terminal acquires a time difference between the second current local time and the first current local time, and the time difference is the above-mentioned time interval.

A third specific example for the user terminal to obtain the above time interval is: when the user terminal receives the measurement control message sent by the network side, it records the first current local time according to the local clock, and the first current local time is the time when the user terminal receives the measurement The local time when the message was controlled. When the user terminal obtains the measurement data, the second current local time is recorded, and the second current local time is the local time when the user terminal obtains the measurement data. The user terminal stores the second current local time and the first current local time, and uses the stored second current local time and the first current local time to represent the time interval.

It can be seen from the above description that the time interval obtained by the user terminal can be represented by the timer value, or by the time difference between the second current local time and the first current local time, or by the second current local time Local time and the first current local time to represent.

It should be noted that a set of measurement data obtained by the user terminal through one measurement corresponds to a time interval. The measurement data obtained for each measurement will correspond to different time intervals.

S120. The user terminal reports the measurement data and the time interval to the network side, so that the network side determines the measurement time of the measurement data according to the time when the measurement control message is delivered and the time interval for receiving it.

In this embodiment, after S101, the process shown in FIG. 1b may be executed.

S121. The user terminal stores the above obtained measurement data and the above time interval.

The user terminal may store the measurement data and the time interval corresponding to the measurement data in the form of Log, so that each piece of log information includes the measurement data and the time interval. In addition, if the user terminal performs measurements periodically, only one piece of log information may include measurement data and time intervals, and other log information may only include measurement data without time intervals. The time interval corresponding to the measurement data in other log information can be calculated and obtained according to the timing period of the measurement. In the case that the time interval is not stored in other log information, the storage space of the user terminal can be saved, and the signaling overhead can be saved when reporting to the network side, so that network resources can be reasonably used. This embodiment does not limit the content specifically included in the measurement data obtained and stored by the user terminal, nor does it limit the specific manner of storing the measurement data and the time interval.

When the user terminal stores the measurement data and the time interval, it may store the measurement data first, and then store the corresponding time interval, or store them simultaneously, which is not limited in this embodiment. Therefore, in actual implementation, S121 may be executed after S110 is executed, or the measurement data may be stored after S101 is executed, and the time interval may be stored after S110 is executed.

S122. When the reporting condition is met, the user terminal reports the stored measurement data and time interval to the network side.

Wherein, the above reporting conditions are used to reduce the network load caused by reporting the measurement data. For example, reporting conditions can be used to implement non-real-time reporting. Specifically, for example, the period/frequency of periodic reporting, the network conditions that need to be met, reporting during or before the location update process, reporting when the memory of the user terminal reaches a predetermined threshold, and so on. The user terminal can report the above measurement data and time interval when the network load is light, thereby reducing the network load. In addition, reporting conditions can also be used to correlate measurement data with location information.

The user terminal can report the measurement data and the time interval corresponding to the measurement data to the network side through various messages. This embodiment does not limit the specific expression form of the reporting condition, nor does it limit the specific message name of the message used to report the measurement data and time interval and message structure.

In addition, the network side here may be the subject of sending the measurement control message. For example, if the radio network controller sends the measurement control message to the user terminal, the user terminal may report the measurement data and time interval to the radio network controller; if If the evolved base station sends a measurement control message to the user terminal, the user terminal can report the measurement data and time interval to the evolved base station; if the OAM sends the measurement control message to the user terminal through the radio network controller or the evolved base station, then The user terminal can report the measurement data and time interval to the OAM through the radio network controller or the evolved base station. In addition, the above-mentioned time for sending the measurement control message may be the time when the network side sends the measurement control message, or it may be the time when the network side receives the confirmation frame returned by the user terminal. The confirmation frame here means that the user terminal correctly receives the measurement control message. The confirmation frame returned by the message.

It should be noted that if the user terminal is handed over and the measurement control message is sent by the radio network controller or the evolved base station, the user terminal can report the measurement data and time interval to the source radio network controller or the source evolved base station, The measurement data and the time interval may also be reported to the handover target radio network controller or target evolved base station. When the user terminal reports measurement data and time intervals to the source radio network controller or the source evolved base station, the source radio network controller or the source evolved base station may determine the accurate measurement time. When the user terminal reports the measurement data and time interval to the target radio network controller or the target evolved base station, the source radio network controller or the source evolved base station needs to transmit the time when the measurement control message is delivered to the target radio network controller or For the target evolved base station, the accurate measurement time is determined by the radio network controller or the target evolved base station.

When the OAM transparently transmits the measurement control message through the evolved base station or the RNC, the evolved base station or the RNC can acquire the time for delivering the measurement control message from the OAM.

In this embodiment, the user terminal reports the measurement data and the time interval, so that the network side can know the measurement time of the measurement data according to the time and time interval of sending the measurement control message. Since the time of sending the measurement control message is the local time of the network side, and the time interval is a relative time difference, the obtained measurement time is more accurate than the local time of the network side, and will not be affected by the local time of the user terminal.

Embodiment 2, the method for obtaining the measurement time. The flow of the method is shown in Figure 2a.

In Fig. 2, S200, the user terminal receives a measurement control message delivered by the network side. The measurement control message here may be that the radio network controller, the evolved base station or the relay station sends the measurement control message to the user terminal, and it may also be that the OAM sends the measurement control message to the user terminal through the radio network controller, the evolved base station or the relay station. The measurement control message may also be sent by other network-side entities, and this embodiment does not limit the name of the specific entity sending the measurement control message.

S201. The user terminal acquires measurement data according to the received measurement control message.

This step can be implemented with reference to S101 in Embodiment 1, and will not be repeated here

S210. The user terminal records the third current local time when the measurement data is obtained.

In S210, the user terminal can obtain measurement data through measurement, and the user terminal can perform measurement according to the measurement control information carried in the measurement control message. When the user terminal obtains the measurement data through measurement, it determines the third current local time according to the local clock, and the third current local time is the local time when the user terminal obtains the measurement data.

S220. The user terminal reports the measurement data, the third current local time and the fourth current local time to the network side.

The fourth current local time is the local time of the user terminal reported by the user terminal to the network side. This embodiment does not limit specific message names, message structures, and the like of the messages used to report the measurement data, the third current local time, and the fourth current local time. In addition, the network side here may be the subject of sending the measurement control message, or may not be the subject of sending the measurement control message. For example, the measurement control message is sent by the source network device, and the measurement data, the third current local time and the fourth current local time are reported to the target network device; or the measurement control message is sent by the OAM, and the measurement data, the third The current local time and the fourth current local time are reported to the evolved base station, RNC or relay station.

It should be noted that a set of measurement data obtained by the user terminal through one measurement corresponds to a third current local time. Multiple sets of measurement data obtained in different measurements correspond to different third current local times. However, if the measurement data of multiple measurements are reported together when reporting, multiple third current local times will be reported, but only one fourth current local time will be reported.

In this embodiment, the process shown in Fig. 2b may also be executed.

For specific implementation of S200, S201, and S210, reference may be made to the example shown in FIG. 2a, and details are not repeated here.

S211. The user terminal stores the obtained measurement data and the third current local time.

The user terminal may store the measurement data and the third current local time in the form of Log, so that each log information includes a set of measurement data and a third current local time. This embodiment does not limit the content specifically included in the measurement data obtained and stored by the user terminal, nor does it limit the specific manner in which the measurement data and the third current local time are stored. Of course, if the user terminal measures periodically, it is preferable to only record the third current local time once, and only record measurement data in other log information, and not record the corresponding third current local time. According to the measurement period and the recorded third current local time, other unrecorded third current local times can be deduced. In this way, the storage content of the user terminal can be reduced, signaling overhead can also be reduced, and network resources can be saved.

S220. When the reporting condition is satisfied, the user terminal reports the stored measurement data, the third current local time and the fourth current local time to the network side, so that the network side can The local time and the local time of the network side when the network side receives the reported data determine the measurement time of the measurement data.

The reporting condition can be implemented with reference to Embodiment 1, and will not be repeated here.

It should be noted that if the user terminal reports immediately after obtaining the last set of measurement data, the above-mentioned fourth current local time may be the third current local time corresponding to the last set of measurement data, that is, the fourth current local time may not be reported any more. Local time; if the user terminal does not report immediately after obtaining the last set of measurement data, the fourth current local time is different from the third current local time corresponding to the last set of measurement data.

In addition, it should be noted that if the user terminal is handed over and the measurement control message is sent by the radio network controller or the evolved base station, the user terminal can report the measurement data to the source radio network controller or the source evolved base station, and the third The current local time and the fourth current local time may also report the measurement data, the third current local time and the fourth current local time to the handover target radio network controller or target evolved base station. When the user terminal reports measurement data and time intervals to the source radio network controller or the source evolved base station, the source radio network controller or the source evolved base station determines the accurate measurement time. When the user terminal reports the measurement data and the time interval to the target radio network controller or the target evolved base station, the target radio network controller or the target evolved base station determines the accurate measurement time.

In this embodiment, the user terminal reports the third current local time and the fourth current local time, so that the network side can obtain a more accurate measurement based on the time difference between the network local time and the fourth current local time when the above reported content is received. Data measurement events reduce the impact of inaccurate local time of user terminals.

Embodiment 3, the method for obtaining the measurement time. The flow of the method is shown in Figure 3.

In FIG. 3, S300. Obtain the time when the network side delivers the measurement control message to the user terminal.

When delivering the measurement control message to the user terminal, the network side may record the time when the measurement control message is delivered. Since the network-side entity that sends the measurement control message and the network-side entity that receives the data reported by the user terminal can be the same network-side entity, or they can be different network-side entities, therefore, in the case of the same network-side entity, the network-side The entity can obtain the time when the measurement control message is delivered from its record information. If they are not the same network-side entity, the network entity that sends the measurement control message can transmit the recorded time of sending the measurement control message to the network-side entity that receives the data reported by the user terminal, so that the receiving user terminal reports The network-side entity of the data can obtain the time for delivering the measurement control message. For example, the time when the target radio network controller or the target evolved base station receives the delivery measurement control message sent by the source radio network controller or the source evolved base station; it can also be the time when the RNC or the evolved base station receives the delivery measurement control message sent by the OAM Control the timing of messages.

When it is determined that the UE needs to be notified to perform measurement, for example, when the network needs to evaluate cell coverage, the network side can send a measurement control message to the user terminal to notify the UE to perform measurement and report according to the conditions specified in the measurement control message. The measurement control message delivered by the network side to the user terminal does not include the reference time provided by the network side to the user terminal. The network side here may be a radio network controller, an evolved base station, a relay station, or an OAM. This embodiment does not limit the specific implementation process of sending the measurement control message by the network side, the specific subject name shown by the network side, and the specific recording method of the time when the measurement control message is sent.

The time recorded by the network side for delivering the measurement control message may be the time when the network side sends the measurement control message, or the time when the network side receives the confirmation frame returned by the user terminal. The confirmation frame here is the time when the user terminal correctly receives the measurement control message. Confirmation frame returned by the message.

S310. Receive the measurement data and time interval reported by the user terminal, where the time interval is: the time interval between the local time when the user terminal obtains the measurement data and the local time when the user terminal receives the measurement control message sent by the network side .

The above time interval is described in detail in Embodiment 1, and will not be described in detail here.

It should be noted that when the user terminal is handed over, if the measurement control message is sent by the source radio network controller or the base station evolved from the source, the subject of receiving the reported measurement data and time interval may be the source radio network controller. The network controller or the source evolved base station may also be the target radio network controller or the target evolved base station. That is to say, the user terminal can report the measurement data and time interval to the source radio network controller or the source evolved base station, and can also report the measurement data and time interval to the target radio network controller or the target evolved base station.

Further, step 301 may also be receiving the measurement data and time interval reported by the user terminal when the reporting condition is met. For the specific implementation of the reporting condition, reference may be made to Embodiment 1, which will not be repeated here.

S320. Determine the measurement time of the measurement data according to the time when the measurement control message is delivered and the time interval for reporting.

The network side may use the sum of the time when the measurement control message is delivered and the time interval reported by the user terminal as the measurement time of the measurement data. Since the measurement data obtained by the user terminal through one measurement corresponds to a time interval, if the measurement data received by the network side is multiple sets of measurement data obtained by the user terminal through multiple measurements, then for each set of measurement data, the network side The measurement time of each set of measurement data can be obtained by using the above-mentioned summing method. Since the time recorded by the network side for delivering the measurement control message is accurate, and the time interval recorded by the user terminal is also accurate, the network side can obtain accurate measurement time.

A specific example of determining the accurate measurement time on the network side: set the time recorded when the network side sends a measurement control message as T, and the measurement data reported by the UE and the time interval corresponding to the measurement data are shown in Table 1:

Table 1

Measurement data The time interval corresponding to the measurement data Measurement data 1 T1 Measurement data 2 T2 Measurement data 3 T3

The exact measurement time of the measurement data determined by the network side using Table 1 is shown in Table 2:

Table 2

Measurement data Accurate measurement time corresponding to measurement data Measurement data 1 T+T1 Measurement data 2 T+T2 Measurement data 3 T+T3

For Table 2, it should be noted that if the time interval reported by the user terminal is expressed by the first current local time and the second current local time, then T1 in the above Table 1 can be expressed as the first current local time T11 and the second current local time The local time is T12, so T+T1 in the above Table 2 is specifically: T+(T12-T11), that is, T12+(T-T11).

Embodiment 4, the method for obtaining the measurement time. The flow of the method is shown in Figure 4.

In FIG. 4, S400. The network side receives the measurement data reported by the user terminal, the third current local time, and the fourth current local time. The above-mentioned third current local time is the local time of the user terminal when the user terminal obtains the measurement data through measurement, and the fourth current local time is the local time of the user terminal when the user terminal reports the measurement data.

It should be noted that if the measurement data reported by the user terminal includes multiple sets of measurement data obtained by the user terminal through multiple measurements, each set of measurement data will correspond to a third current local time, and the third set of measurement data corresponding to different sets The current local time is usually not the same. In addition, regardless of whether the measurement data reported by the user terminal includes multiple pieces of measurement data obtained by the user terminal through multiple measurements, or includes one piece of measurement data obtained by the user terminal through one measurement, the data reported by the user terminal to the network side may only include one 4 The current local time. In addition, it should be noted that if the user terminal reports immediately after obtaining the last set of measurement data, the above-mentioned fourth current local time may be the third current local time corresponding to the last set of measurement data; if the user terminal obtains the last set of measurement data If the data is not reported immediately, the fourth current local time is different from the third current local time corresponding to the last set of measurement data. In addition, in the case that the user terminal is handed over, if the measurement control message is sent by the source radio network controller or the source evolved base station, the reported measurement data, the third current local time and the fourth current local time are received The subject of time may be the source radio network controller or the source evolved base station, or may be the target radio network controller or the target evolved base station. That is to say, the user terminal can report the measurement data, the third current local time and the fourth current local time to the source radio network controller or the source evolved base station, and can also report the measurement data to the target radio network controller or the target evolved base station , the third current local time and the fourth current local time.

Further, in this step, the measurement data, the third current local time, and the fourth current local time reported by the user terminal when the reporting condition is met may also be received.

S410. The network side determines the measurement time of the measurement data according to the received third current local time and fourth current local time, and the network side local time when the network side receives the reported data.

Specifically, for a set of measurement data, the network side may first calculate the difference between the network side local time when the network side receives the reported data and the fourth current local time, and then compare the third current local time of the measurement data with the fourth current local time The difference is summed, and the calculated result of the sum is the measurement time of the measured data. Since the difference between the fourth current local time and the third current local time is accurate, and the local time on the network side when the network side receives the reported data is also accurate, the measurement time of the finally obtained measurement data is also accurate .

A specific example for the network side to determine the accurate measurement time: set the network local time when the network side receives the reported data as t, the measurement data reported by the user terminal, the third current local time and the fourth current local time corresponding to the measurement data The time is shown in Table 3:

Embodiment 5, the method for obtaining the measurement time. The flow of the method is shown in Figure 5.

In Fig. 5, S500 and RNC/eNodeB deliver an MDT measurement control (MDT measurement control) message to the UE.

S510. The RNC/eNodeB receives the ACK (confirmation) message for the MDT measurement control returned by the UE.

The RNC/eNodeB can time stamp the UEmeasurement context (UE measurement context) after sending the MDT measurement control message, and the RNC/eNodeB can also time stamp the UE measurement context after receiving the ACK message, such as 10h:30m.

S520. After receiving the MDT measurement control message, the UE triggers the MDT timer to start timing. The MDT timer can be sent to the UE by the network side through SIB1 (System Information Block1, system message 1) or UTRAN MOBILITY INFORMATION (Universal Mobile Communication System Access Network Mobile Information) and other messages. In addition, the MDT timer can also not It is issued by the network side, but an MDT timer is standardized in the protocol. The value of the MDT timer can be infinite. The UE can restart the MDT timer after receiving the MDT measurement control message, otherwise, the MDT timer does not stop.

S530. When the measurement data recording criterion is reached, the UE stamps each log according to the timing value of the MDT timer, that is, when it is determined according to the recording criterion that the measurement data obtained through measurement needs to be stored, stamp each log according to the UE local clock timestamp. In addition, when the measurement data recording criterion is periodic, the UE may only time stamp one log, and the time stamps of other logs may be calculated according to the period of the recording criterion and the time stamps of the above logs.

S540. When the reporting threshold is reached, the UE reports the recorded log list to the RNC/eNodeB through an MDT measurement report (MDT measurement report) message.

S550. After receiving the MDT measurement report message, the RNC/eNodeB calculates the accurate measurement time corresponding to each log according to the time stamp recorded in the UE measurement context and the time stamp carried in the MDT measurement report message reported by the UE.

A specific example of S550 is: the RNC/eNodeB stamps the UE measurement context as 10h:30m, and the UE reports n logs, where Log1 includes measurement data 1 and t1, Log2 includes measurement data 2 and t2, and Logn Including measurement data n and tn; RNC/eNodeB calculates the measurement time of measurement data 1 in Log1 as: 10h:30m+t1; RNC/eNodeB calculates the measurement time of measurement data 2 in Log2 as: 10h:30m+t2 ; RNC/eNodeB calculates the measurement time of the measurement data n in Logn as: 10h:30m+tn.

In a mobile scenario, after UE reselection or UE handover to another RNC/eNodeB, if the UE stores measurement data obtained through measurement under the source RNC/source eNodeB, the following two processing methods can be used:

Method 1. The UE reports the log obtained through measurement under the source RNC/source eNodeB to the target RNC/target eNodeB, and the target RNC/target eNodeB forwards the log to the source RNC/source eNodeB. In this way, the source RNC/source eNodeB can The received logs use the method described in the fifth embodiment above to determine the measurement time of the measurement data in each log.

Method 2: The source RNC/source eNodeB forwards the UE measurement context to the target RNC/target eNodeB, and the UE reports the log obtained through measurement under the source RNC/source eNodeB to the target RNC/target eNodeB. In this way, the target RNC/target eNodeB according to The received UE measurement context and logs use the method described in Embodiment 5 to determine the measurement time of the measurement data in each log.

Embodiment 6, the method for obtaining the measurement time. The flow of the method is shown in Figure 6.

S600. The RNC/eNodeB sends an MDT measurement control (MDT measurement control) message to the UE.

S610. The RNC/eNodeB receives the ACK (confirmation) message for the MDT measurement control returned by the UE.

The RNC/eNodeB can time stamp the UEmeasurement context (UE measurement context) after sending the MDT measurement control message, and the RNC/eNodeB can also time stamp the UE measurement context after receiving the ACK message, such as 10h:30m.

S620. After receiving the MDT measurement control message, the UE sets the time offset as the local current time of the UE.

S630. When the measurement data recording criterion is reached, the UE timestamps each log according to the offset, that is, when it is determined according to the recording criterion that the measurement data obtained through measurement needs to be stored, according to the difference between the local current time when the measurement data is obtained and the offset Timestamp each log. In addition, when the measurement data recording criterion is periodic, the UE may only time stamp one log, and the time stamps of other logs may be calculated according to the period of the recording criterion and the time stamps of the above logs.

S640. When the reporting threshold is reached, the UE reports the recorded log list to the RNC/eNodeB through an MDT measurement report (MDT measurement report) message.

S650. After receiving the MDT measurement report message, the RNC/eNodeB calculates the accurate measurement time corresponding to each log according to the time stamp recorded in the UE measurement context and the time stamp carried in the MDT measurement report message reported by the UE.

A specific example of S650 is: the RNC/eNodeB stamps the UE measurement context as 10h:30m, and the UE reports n logs, where Log1 includes measurement data 1 and t1-offset (t1 is the time stamp for obtaining measurement data 1 UE local current time), Log2 includes measurement data 2 and t2-offset (t2 is UE local current time for obtaining measurement data 2), Logn includes measurement data n and tn-offset (tn is UE local current time for obtaining measurement data n ); RNC/eNodeB calculates the measurement time of measurement data 1 in Log1 as: 10h:30m+t1-offset; RNC/eNodeB calculates the measurement time of measurement data 2 in Log2 as: 10h:30m+t2-offset; The RNC/eNodeB calculates the measurement time of the measurement data n in Logn as: 10h:30m+tn-offset.

In a mobile scenario, after the UE reselects or the UE switches to another RNC/eNodeB, if the UE stores the measurement data obtained through measurement under the source RNC/source eNodeB, it is basically the same as the two methods exemplified in the fifth embodiment above. The same, the difference is that in the first method, the source RNC/source eNodeB adopts the method described in Embodiment 6 to determine the measurement time of the measurement data in each log, and in the second method, the target RNC/target eNodeB adopts the method described in Embodiment 6 The method determines the measurement time of the measurement data in each log, which will not be described in detail here.

Embodiment 7, the method for obtaining the measurement time. The flow of this method is shown in Figure 7.

S700. The OAM sends an MDT measurement request (MDT measurement request) message to the RNC/eNode based on a certain strategy, and stamps the UE measurement context with a timestamp, such as 10h:30m.

S710. After receiving the MDT measurement request, the RNC/eNodeB sends an MDT measurement control (MDT measurement control) message to the UE.

S720. After receiving the MDT measurement control message, the UE triggers the MDT timer to start timing. The MDT timer can be sent to the UE by the network side through SIB1 or UTRAN MOBILITY INFORMATION and other messages. In addition, the MDT timer can not be sent by the network side, but an MDT timer can be standardized in the protocol. The value of the MDT timer can be infinite. The UE can restart the MDT timer after receiving the MDT measurement control message, otherwise, the MDT timer does not stop.

S730. When the measurement data recording criterion is reached, the UE stamps each log according to the timing value of the MDT timer, that is, when it is determined according to the recording criterion that the measurement data obtained through measurement needs to be stored, stamp each log according to the UE local clock timestamp. In addition, when the measurement data recording criterion is periodic, the UE may only time stamp one log, and the time stamps of other logs may be calculated according to the period of the recording criterion and the time stamps of the above logs.

S740. When the reporting threshold is reached, the UE reports the recorded log list to the RNC/eNodeB through an MDT measurement report (MDT measurement report) message.

S750. After receiving the MDT measurement report message, the RNC/eNodeB forwards the log in the MDT measurement report message to the OAM through an MDT measurement response (MDT measurement response) message.

S760. The OAM calculates the accurate measurement time corresponding to each log according to the time stamp recorded in the UE measurement context and the time stamp carried in the received MDT measurement response message.

A specific example of S760 is: the OAM stamps the UE measurement context as 10h:30m, and the UE reports n logs, where Log1 includes measurement data 1 and t1, Log2 includes measurement data 2 and t2, and Logn includes measurement data Data n and tn; OAM calculates the measurement time of measurement data 1 in Log1 as: 10h:30m+t1; OAM calculates the measurement time of measurement data 2 in Log2 as: 10h:30m+t2; OAM calculates the measurement time of Logn The measurement time of the measurement data n is: 10h:30m+tn.

S820. After receiving the MDT measurement control message, the UE sets the time offset as the local current time of the UE.

S830. When the measurement data recording criterion is reached, the UE timestamps each log according to the offset, that is, when it is determined according to the recording criterion that the measurement data obtained through measurement needs to be stored, according to the difference between the local current time when the measurement data is obtained and the offset Timestamp each log. In addition, when the measurement data recording criterion is periodic, the UE may only time stamp one log, and the time stamps of other logs may be calculated according to the period of the recording criterion and the time stamps of the above logs.

S840. When the reporting threshold is reached, the UE reports the recorded log list to the RNC/eNodeB through an MDT measurement report (MDT measurement report) message.

When the first reporting module 1130 reports the measurement data and time interval to the source radio network controller or the source evolved base station, the source radio network controller or the source evolved base station may determine the accurate measurement time. When the first reporting module 1130 reports the measurement data and time interval to the target radio network controller or the target evolved base station, the source radio network controller or the source evolved base station needs to transmit the time when the measurement control message is delivered to the target wireless network The controller or the target evolved base station determines the accurate measurement time by the radio network controller or the target evolved base station.

The apparatus for obtaining measurement time provided in this embodiment may be used, for example, to execute the method for obtaining measurement time provided in Embodiment 1 and other corresponding method embodiments.

Embodiment 12: Obtaining a device for measuring time. The device is shown in Figure 12. The device can be set, for example, in a user terminal.

The device in FIG. 12 a includes: a second receiving module 1200 , a second measuring module 1201 , a recording module 1202 and a second reporting module 1220 .

The second receiving module 1200 is configured to receive the measurement control message delivered by the network side. The measurement control message received by the second receiving module 1200 may be that the radio network controller or the evolved base station sends the measurement control message to the user terminal, or it may be that the OAM sends the measurement control message to the user terminal through the radio network controller or the evolved base station . The measurement control message may also be sent by other network-side entities, and this embodiment does not limit the name of the specific entity sending the measurement control message.

The second measurement module 1201 is configured to obtain measurement data according to the measurement control message received by the second receiving module 1200 .

The recording module 1202 is configured to record the third current local time when the second measuring module 1201 obtains the measurement data.

When the measurement data is obtained, the recording module 1202 stores the third current local time according to the local clock, and the third current local time is the local time when the second measurement module 1201 obtains the measurement data.

It should be noted that if the user terminal reports immediately after obtaining the last set of measurement data, the above-mentioned fourth current local time may be the third current local time corresponding to the last set of measurement data; if the user terminal obtains the last set of measurement data If it is not reported immediately afterwards, the fourth current local time is different from the third current local time corresponding to the last set of measurement data.

In addition, it should be noted that if the user terminal is handed over and the measurement control message is sent by the radio network controller or the evolved base station, the second reporting module 1220 may report the measurement data to the source radio network controller or the source evolved base station , the third current local time, and the fourth current local time.

When the second reporting module 1220 reports the measurement data and time interval to the source radio network controller or the source evolved base station, the source radio network controller or the source evolved base station determines the accurate measurement time. When the second reporting module 1220 reports the measurement data and the time interval to the target radio network controller or the target evolved base station, the target radio network controller or the target evolved base station determines the accurate measurement time.

The device for obtaining measurement time provided in this embodiment of the present invention may, for example, execute the method for obtaining time provided in Embodiment 2 and other corresponding method embodiments.

Embodiment 13 provides a network device. The network device may be a radio network controller, or an evolved base station, an OAM, or a relay station. The network device is shown in FIG. 13 .

The network device in FIG. 13 includes: an acquiring module 1300 , a second receiving module 1310 and a first time module 1320 .

The obtaining module 1300 is configured to obtain the time when the measurement control message is delivered to the user terminal.

The acquiring module 1300 may record the time when the measurement control message is delivered by the network side when the measurement control message is delivered to the user terminal. Since the network-side entity that sends the measurement control message and the network-side entity that receives the data reported by the user terminal can be the same network-side entity, or they can be different network-side entities, therefore, in the case of the same network-side entity, the acquisition module 1300 may acquire the time of sending the measurement control message from its record information. If they are not the same network-side entity, the network entity sending the measurement control message can transmit the recorded time of sending the measurement control message to the network-side entity receiving the data reported by the user terminal, so that the acquisition module 1300 can Obtain the time when the measurement control message is delivered. For example, the acquisition module 1300 in the target radio network controller or the target evolved base station receives the time when the measurement control message is sent from the source radio network controller or the source evolved base station; for example, the radio network controller or the target evolved base station or The relay station obtains the time of delivering the measurement control message from the OAM.

In the above case of the same network-side entity, the time when the measurement control message is delivered recorded by the acquisition module 1300 may be the time when the network side sends the measurement control message, or the time when the network side receives the confirmation frame returned by the user terminal. Here The acknowledgment frame is the acknowledgment frame returned by the user terminal after correctly receiving the measurement control message.

The second receiving module 1310 is configured to receive the measurement data and the time interval reported by the user terminal to the network side, and the time interval is: between the local time when the user terminal obtains the measurement data and the local time when the user terminal receives the measurement control message time interval. The time interval can be represented by the timing value of the timer, or by the time difference between the second current local time and the first current local time, or by the second current local time and the first current local time express.

In the case that the user terminal is handed over, if the measurement control message is sent by the source radio network controller or the source evolved base station, the second receiving module 1310 that receives the reported measurement data and time interval may be the source radio network The controller or a module in the source evolved base station may also be a target radio network controller or a module in the target evolved base station. That is to say, the user terminal can report the measurement data and time interval to the source radio network controller or the source evolved base station, and can also report the measurement data and time interval to the target radio network controller or the target evolved base station.

When the user terminal reports the measurement data and time interval to the target radio network controller or the target evolved base station, the acquiring module 1300 acquires the measurement data delivered to the user terminal from the message transmitted by the source radio network controller or the source evolved base station Control the timing of messages.

The first time module 1320 is configured to determine the measurement time of the measurement data according to the time obtained by the obtaining module 1300 and the time interval received by the second receiving module 1310 .

The first time module 1320 may use the sum of the time when the measurement control message is delivered and the time interval reported by the user terminal as the measurement time of the measurement data. Since the measurement data obtained by the user terminal through one measurement corresponds to a time interval, if the measurement data received by the second receiving module 1310 is multiple sets of measurement data obtained by the user terminal through multiple measurements, for each set of measurement data , the first time module 1320 can obtain the measurement time of each set of measurement data by using the above-mentioned summing method. Since the time recorded by the network side for delivering the measurement control message is accurate, and the time interval recorded by the user terminal is also accurate, the first time module 1320 can obtain accurate measurement time.

The network device provided in this embodiment of the present invention may be used, for example, to execute the method for obtaining measurement time provided in Embodiment 3 and other corresponding method embodiments.

Embodiment 14 provides a network device. The network device may be a radio network controller, or an evolved base station, or an OAM, or a relay station. The network device is shown in FIG. 14 .

The third receiving module 1400 is configured to receive the measurement data, the third current local time, and the fourth current local time reported by the user terminal to the network side when the reporting condition is satisfied, where the third current local time is when the user terminal obtains the measurement data The local time of the user terminal, the fourth current local time is the local time of the user terminal when the user terminal reports the measurement data.

The measurement data received by the third receiving module 1400 may include multiple sets of measurement data obtained by the user terminal through multiple measurements, each set of measurement data corresponds to a third current local time, and the third current local time corresponding to different sets of measurement data Times are usually not the same. In addition, whether the measurement data received by the third receiving module 1400 includes multiple pieces of measurement data obtained by the user terminal through multiple measurements, or includes one piece of measurement data obtained by the user terminal through one measurement, the reported data received by the third receiving module 1400 may only include a fourth current local time. In addition, if the user terminal reports immediately after obtaining the last set of measurement data, the fourth current local time received by the third receiving module 1400 may be the third current local time corresponding to the last set of measurement data; if the user terminal obtains the last If a set of measurement data is not reported immediately, the fourth current local time received by the third receiving module 1400 is different from the third current local time corresponding to the last set of measurement data.

In the case that the user terminal is handed over, if the measurement control message is sent by the source radio network controller or the source evolved base station, receive the reported measurement data, the third current local time and the fourth current local time. The third receiving module 1400 may be a module in the source radio network controller or the source evolved base station, and may also be a module in the target radio network controller or the target evolved base station. That is to say, the user terminal can report the measurement data, the third current local time and the fourth current local time to the source radio network controller or the source evolved base station, and can also report the measurement data to the target radio network controller or the target evolved base station , the third current local time and the fourth current local time.

The second time module 1410 is configured to determine the measurement time of the measurement data according to the third current local time, the fourth current local time, and the network side local time when the third receiving module receives the reported data.

For a set of measurement data, the second time module 1410 may first calculate the difference between the local time on the network side when the third receiving module 1400 receives the reported data and the fourth current local time, and then the second time module 1410 converts the measurement data to The third current local time and the above difference are summed, and the calculation result of the sum is the measurement time of the measurement data. Since the difference between the fourth current local time and the third current local time is accurate, and the local time on the network side when the third receiving module 1400 receives the reported data is also accurate, the second time module 1410 finally obtains The measurement time of the measurement data is also accurate.
