The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1A is a schematic diagram of an application scenario of the following embodiments of the present invention. As shown in FIG. 1A, the application scenario includes a macro base station and a low power node (Low Power Node, LPN for short). LPN can be Wireless Fidelity (WiFi) Access Point (Access) Point, abbreviated as AP), a base station in a Pico cell or a base station in a small (Smal l) cell, etc., these LPNs have a small coverage range, and the coverage radius is generally from several tens to several hundreds of meters. The coverage of the macro base station is usually larger than the coverage of the LPN.

The UE typically performs measurement and report triggering based on the measurement configuration information of the base station. At this time, the base station controls the UE to switch to the neighboring cell according to the measurement report reported by the UE. As shown in FIG. 1A, when the UE is in medium-and high-speed mobile, if the UE is switched to the LPN cell, since the coverage of the LPN is small, the UE will quickly cut out from the LPN cell, and such unnecessary handover will occur. This causes the consumption of network resources, and at the same time, the service is interrupted due to the handover. The following embodiments of the present invention provide a solution to the problem. FIG. 1B is a flowchart of a measurement method according to an embodiment of the present invention. As shown in FIG. 1B, the method includes:

The UE receives the measurement configuration information sent by the base station, where the measurement configuration information carries a report trigger condition, where the report trigger condition includes a signal change trigger condition, and the signal change trigger condition is a wireless signal reception strength or a wireless signal of the neighboring cell. The range of variation of the reception quality during the monitoring period is less than the variation threshold.

In this embodiment, the measurement configuration information sent by the base station to the UE not only indicates that the UE performs measurement on the neighboring cell, but the measurement configuration information further carries a report trigger condition for instructing the UE to perform a measurement report when the report trigger condition is met. Reported. Further, in this embodiment, in order to solve the problem that the base station performs mobility handover on the UE according to the reporting of the measurement report, the UE may control the UE to frequently perform cell handover, and the report triggering condition sent by the base station to the UE includes a signal change trigger condition. Optionally, the signal change triggering condition may be that the wireless signal receiving strength of the neighboring cell or the wireless signal receiving quality is less than a variation threshold in the monitoring period, that is, when the UE monitors the wireless signal receiving strength of a neighboring cell. The reporting of the measurement report is triggered only when the wireless signal reception quality is less than the change threshold during the monitoring period. The radio signal receiving strength of the neighboring cell may be Reference Signal Received Power (RSRP) or Received Channel Power Indicator (RCPI), but is not limited thereto. The radio signal reception quality of the neighboring cell may be Reference Signal Receiving Quality (RSRQ) or Received Signal to Noise Indicator (RSNI), but is not limited thereto. Among them, RCPI is mainly used to reflect the signal strength of the WiFi channel; RSNI is mainly used to reflect the WiFi letter. The interference situation of the road.

In this embodiment, the parameters such as the change threshold and the monitoring period in the signal change trigger condition may be flexibly configured by the base station according to the application scenario. For example, the base station may configure these parameters as cell-level parameters, that is, the monitoring period and/or the change threshold in the signal change triggering conditions corresponding to different cells of the same working frequency band may be different. In addition, the base station may also configure these parameters as frequency band level parameters, that is, the monitoring time period and/or the change threshold in the signal change trigger condition corresponding to the cells in different working frequency bands may be different. The working frequency band can be a carrier. Alternatively, parameters such as a change threshold and a monitoring period in the signal change trigger condition may also be specified by a protocol.

It is noted herein that the monitoring period in the signal change triggering condition may be determined by the coverage range of the neighboring cell. Generally, the larger the coverage of the neighboring cell, the longer the monitoring period. The change threshold in the signal change trigger condition may be determined by signal attenuation of the neighboring cell and the moving speed of the UE, but is not limited thereto. For example, if the moving speed of the UE that wants to be restricted is 60 kilometers per hour, and the coverage radius of the neighboring cell is 200 meters, the distance that the UE moves 200 meters takes about 12 seconds, and the monitoring period should be less than 12 seconds; Set to 1 second, then 1 second moves 16.7 meters. If the signal attenuation of the neighboring cell is X in the range of 16.7 meters, the configured change threshold can be x.

Taking the LTE system as an example, the related content of step 101 will be described. In the LTE system, the base station may send a Radio Resource Control (RRC) connection reconfiguration message to the UE, where the RRC connection reconfiguration message includes a measurement configuration (measConfig) cell, and the measConfig cell is used to configure the measurement. Configuration information. In this embodiment, in addition to the existing measurement configuration information, the measConfig cell adds a new report trigger condition, that is, a signal change trigger condition, and the UE can trigger the measurement report only when the signal change trigger condition is satisfied. The signal change trigger condition, for example, may include a change threshold and/or a monitoring period. The signal change trigger condition can be at the band level, that is, one band corresponds to one signal change trigger condition. The signal change triggering condition may also be a more detailed cell level, that is, some cells in a frequency band may be configured with a signal change trigger condition, and some may not be configured. For a cell configured with a signal change trigger condition, different change thresholds may be configured. And monitoring time.

102. The UE performs, according to the measurement configuration information, a signal of the neighboring cell. After receiving the measurement configuration information sent by the base station, the UE measures the signal of the neighboring cell according to the indication of the measurement configuration information. The neighboring cells may include, but are not limited to, a micro cell (Pico cel l ), a small cell (smal l cel l ), a WiFi access point, and a macro cell. 103. When the measurement result determined by the UE is that the neighboring cell meets the signal change trigger condition, generate a measurement report and report the measurement report to the base station.

In this embodiment, the UE monitors the signal change of the neighboring cell in the monitoring period specified by the signal change triggering condition, and determines whether the neighboring cell satisfies the signal change triggering condition according to the measurement result of the neighboring cell, in the judgment result. To be satisfied, a measurement report is generated and reported to the base station. The measurement report includes a cell (possibly one or more) that triggers the measurement report, and a radio signal reception strength or radio signal reception quality of the cell, for example, information such as RSRP or RSRQ.

In this embodiment, the measurement report is used by the base station to determine whether to switch the UE to the neighboring cell.

In this embodiment, the UE does not report the measurement report when the wireless signal receiving strength of the neighboring cell or the wireless signal receiving quality in the monitoring period is greater than or equal to the change threshold, that is, the UE is in the middle and high speed motion. The measurement report is not reported in the state, and the measurement report is reported only when the wireless signal reception strength of the adjacent cell or the wireless signal reception quality changes within the monitoring period is smaller than the variation threshold, that is, the UE is only at low speed or stationary. The measurement report is reported to the base station, and the base station performs mobility management on the UE after receiving the measurement report reported by the UE, for example, controlling the UE to perform cell handover, or adding a cell that triggers the measurement report as the secondary cell. (SCel l), etc. Compared with the prior art, the method provided in this embodiment solves the problem that the UE in the prior art frequently performs cell handover in a medium-and high-speed mobile scenario, and is beneficial to reducing the base station based on the measurement report. The UE performs unnecessary switching caused by the mobility management process, which is advantageous. Save network resources, reduce business interruption, thereby improving the user experience.

In an optional implementation manner of the embodiment shown in FIG. 1B, the report triggering condition carried by the measurement configuration information further includes a signal strength/quality trigger condition. Based on this, the method further includes: determining, by the UE, that the neighboring cell satisfies the signal strength/quality trigger condition according to the radio signal receiving strength or the radio signal receiving quality of the neighboring cell. In the embodiment of the present invention, the UE determines, according to the radio signal receiving strength or the radio signal receiving quality of the neighboring cell, that the neighboring cell meets the signal strength/quality triggering condition, and determines that the neighboring cell is satisfied by the UE. The sequence between the steps of the signal change trigger condition is not limited.

The process of determining, by the UE, whether the neighboring cell meets the signal strength/quality triggering condition according to the radio signal receiving strength or the radio signal receiving quality of the neighboring cell includes: According to the signal strength/quality triggering condition sent by the base station, the signal of the neighboring cell is measured to obtain the wireless signal receiving strength or the wireless signal receiving quality of the neighboring cell, based on the measured wireless signal receiving strength or wireless signal receiving quality of the neighboring cell. Determining whether the neighboring cell satisfies the signal strength/quality trigger condition. For example, for the A3 measurement event, the UE measures the signal of the neighboring cell according to the signal strength/quality triggering condition sent by the base station to obtain the RSRP of the neighboring cell. When determining whether to trigger the measurement report, the UE first determines the measured neighboring cell. If the RSRP is higher than the specified threshold of the serving cell, if the judgment result is yes, and the base station is also configured with the Time To Trigger mechanism, the UE further determines whether the configured trigger time has been met. The RSRP of the neighboring cell is higher than the specified threshold by the RSRP of the serving cell, and if yes, it is determined that the neighboring cell satisfies the signal strength/quality trigger condition.

In an optional implementation manner, as shown in FIG. 2A, the method includes:

The UE receives the measurement configuration information sent by the base station, where the measurement configuration information carries a report trigger condition, the report trigger condition includes a signal change trigger condition, and the signal change trigger condition is a wireless signal reception strength or a wireless signal of the neighboring cell. The range of variation of the reception quality during the monitoring period is less than the variation threshold.

202. The UE performs, according to the measurement configuration information, a signal of the neighboring cell.

203a. The UE determines, according to the measured wireless signal receiving strength or wireless signal receiving quality of the neighboring cell, that the neighboring cell meets the signal strength/quality triggering condition.

203. The UE determines whether the measurement result is that the neighboring cell satisfies the signal change trigger condition. When the determination is satisfied, step 204 is performed. When the determination is not met, the operation ends.

204. Generate a measurement report and report the measurement report to the base station.

The foregoing steps 201, 202, 203a, and 203 can be referred to the description of the embodiment shown in FIG. 1B, and details are not described herein again.

Based on the above, the start timing for the UE to monitor the signal change of the neighboring cell can be divided into two types, which will be separately described below.

One way is to initiate signal change monitoring when the neighboring cell satisfies the signal strength/quality trigger condition or when the neighboring cell satisfies the signal strength/quality trigger condition. Based on this, determining, by step 103 or step 203, whether the measurement result is that the neighboring cell meets the signal change triggering condition includes: determining, by the UE, that the neighboring cell meets the signal strength/quality trigger condition Thereafter, wireless signal reception strength or wireless signal reception to the neighboring cell The quality is monitored, and it is determined whether the wireless signal receiving strength of the neighboring cell or the wireless signal receiving quality is smaller than the change threshold in the monitoring period, and if the determination result is yes, determining that the neighboring cell satisfies the signal The change trigger condition, if the judgment result is no, it is determined that the neighboring cell does not satisfy the signal change trigger condition. In this implementation manner, the monitoring period is: a period of time since the UE determines that the neighboring cell meets the signal strength/quality trigger condition.

The specific process of the foregoing implementation manner may be: when determining that the neighboring cell meets the signal strength/quality trigger condition, the UE starts signal change monitoring, and starts a signal change monitoring timer, where the timing duration is monitoring in a signal change trigger condition. The length of the time period, after the timer expires, if the monitored neighboring cell's wireless signal reception strength or wireless signal reception quality varies

(For example, the variation range here may be the difference between the monitored wireless signal reception intensity or the minimum value and the maximum value of the wireless signal reception quality during the timer, or the maximum value of the wireless signal reception intensity or the wireless signal reception quality. The difference between the minimum values) is less than the change threshold, triggering the generation and reporting of the measurement report. The advantage of this implementation is that the UE only needs to perform simple function expansion on the basis of implementing the existing report trigger condition, and therefore, it is not necessary to extend the judgment function for the signal change trigger condition after implementing the existing report trigger condition function, so It is relatively simple to implement changes to the functionality of the existing report trigger conditions.

Another way is to monitor the wireless signal reception strength or the wireless signal reception quality of the neighboring cell during the measurement of the neighboring cell, and store the wireless signal reception strength or wireless signal reception of the neighboring cell monitored for a period of time. quality. Based on this, determining, by step 103 or step 203, whether the measurement result is that the neighboring cell meets the signal change trigger condition includes: determining, by the UE, that the neighboring cell meets the signal strength/quality trigger condition After determining whether the wireless signal receiving strength of the neighboring cell or the wireless signal receiving quality is less than the change threshold in the monitoring period, if the determination result is yes, determining that the neighboring cell satisfies the signal change The trigger condition, if the determination result is no, determines that the neighboring cell does not satisfy the signal change trigger condition. In this implementation manner, the monitoring period is: a period of time when the UE determines that the neighboring cell meets the signal strength/quality trigger condition, that is, saves the wireless signal receiving strength or wireless signal reception monitored to the neighboring cell. Quality for a while.

The specific process of the foregoing implementation manner may be: the UE starts monitoring the wireless signal receiving strength or the wireless signal receiving quality of the neighboring cell during the measurement of the neighboring cell, and saves the time period. The radio signal reception strength or the radio signal reception quality of the neighboring cell monitored in the inter-cell, and when the neighboring cell satisfies the report trigger condition, the radio signal reception strength of the neighboring cell saved in the period of the monitoring period is viewed backward Or the range of variation of the wireless signal reception quality, the change range is compared with the change threshold, and if it is less than the change threshold, the generation and reporting of the measurement report is triggered. The advantage of this implementation is that the wireless signal receiving strength or the wireless signal receiving quality of the neighboring cell is monitored before determining that the neighboring cell satisfies the signal strength/quality triggering condition, and once the neighboring cell is determined to satisfy the signal strength/quality triggering condition, Comparing the previously received wireless signal reception strength or the variation range of the wireless signal reception quality with the change threshold, and reporting the measurement report according to the comparison result in time, since it is not necessary to wait after determining that the adjacent cell satisfies the signal strength/quality trigger condition The monitoring of the radio signal reception strength or the reception quality of the radio signal of the neighboring cell is small, and the reporting delay of the measurement report is small.

The signal strength/quality trigger condition is that the radio signal reception strength of the neighboring cell or the radio signal reception quality always meets the specified threshold within the time to Trigger. Based on this, for the second case, the second monitoring period can be less than or equal to the duration of the triggering time. Preferably, the second monitoring period may be equal to the duration of the triggering time, that is, when the timer corresponding to the triggering time is started, the signal change monitoring is started. This method can simplify the implementation of the UE and has less impact on the standard.

As shown in FIG. 2B, it is a comparison result between the embodiment of the present invention and the prior art solution. It can be seen from FIG. 2B that the trigger point reported by the measurement report in the embodiment of the present invention is lagging behind the trigger point reported by the measurement report in the prior art, thereby reducing unnecessary necessity for the base station to perform mobility management on the UE based on the report of the measurement report. Manage operations.

Further, based on the foregoing embodiments or the foregoing, the UE may check whether the wireless signal receiving strength or the wireless signal receiving quality of the current neighboring cell is higher than a threshold before determining to report the measurement report. If the threshold is not higher than the threshold, Report the measurement report.

It can be seen from the above that in the mode of the embodiment, the triggering measurement report needs to meet the signal strength/signal quality triggering condition as required by the current protocol, and needs to meet the signal change triggering condition to trigger the measurement report, that is, only the UE is considered to be moving at a low speed or When the measurement report is reported in the quiescent state, it is beneficial to reduce the unnecessary handover of the base station to the UE in the mobility management process based on the reporting of the measurement report, which is beneficial to saving network resources and reducing service interruption, thereby improving the user experience.

FIG. 3 is a flowchart of a measurement control method according to an embodiment of the present invention. As shown in Figure 3, The method includes:

301. The base station sends measurement configuration information to the UE, where the measurement configuration information carries a report trigger condition, where the report trigger condition includes a signal change trigger condition, and the signal change trigger condition is a wireless signal reception strength or wireless signal reception of the neighboring cell. The range of variation of quality during the monitoring period is less than the threshold of variation.

The base station receives the measurement report reported by the UE, where the measurement report is that the UE measures the signal of the neighboring cell according to the measurement configuration information, and determines that the measurement result is that the neighboring cell meets the signal change trigger. Generated and sent after the condition.

This embodiment is a description from the perspective of a base station. In this embodiment, the measurement configuration information sent by the base station to the UE not only indicates that the UE performs measurement on the neighboring cell, but the measurement configuration information further carries a report trigger condition for instructing the UE to perform a measurement report when the report trigger condition is met. Reported. Further, in this embodiment, in order to solve the problem that the UE performs mobility handover according to the measurement report reported by the UE, it may control the UE to frequently perform cell handover and the like, and the report trigger condition sent by the base station to the UE includes a signal change trigger condition. Optionally, the signal change triggering condition may be that the wireless signal receiving strength of the neighboring cell or the wireless signal receiving quality is less than a variation threshold in the monitoring period, that is, when the UE monitors the wireless signal receiving strength of a neighboring cell. The reporting of the measurement report is triggered only when the wireless signal reception quality is less than the change threshold within the monitoring period. The radio signal receiving strength of the neighboring cell may be RSRP or RCPI, but is not limited thereto. The radio signal reception quality of the neighboring cell may be RSRQ or RSNI, but is not limited thereto. Among them, RCPI is mainly used to reflect the signal strength of the WiFi channel; RSNI is mainly used to reflect the interference of the WiFi channel.

The neighboring cells may include, but are not limited to, a micro cell (Pico cel l ), a small cell (small cel l ), a WiFi access point, and a macro cell.

In this embodiment, the parameters such as the change threshold and the monitoring period in the signal change trigger condition may be flexibly configured by the base station according to the application scenario. For example, the base station may configure the parameters as cell level parameters, that is, the monitoring period and/or the change threshold in the signal change trigger condition corresponding to different cells of the same working frequency band may be different. In addition, the base station may also configure the parameters as the band level parameters, that is, the monitoring period and/or the change threshold in the signal change trigger condition corresponding to the cells in different working bands may be different. The working frequency band can be a carrier. Alternatively, parameters such as a change threshold and a monitoring period in the signal change trigger condition may also be specified by a protocol. It is to be noted that the monitoring period in the signal change triggering condition may be determined by the coverage of the neighboring cell. Generally, the coverage of the neighboring cell is larger, and the monitoring period is longer. The change threshold in the signal change trigger condition may be determined by signal attenuation of the neighboring cell and the moving speed of the UE, but is not limited thereto. For example, if the moving speed of the UE that wants to be restricted is 60 kilometers per hour, and the coverage radius of the neighboring cell is 200 meters, the distance that the UE moves 200 meters takes about 12 seconds, and the monitoring period should be less than 12 seconds; Set to 1 second, then 1 second moves 16.7 meters. If the signal attenuation of the neighboring cell is X in the range of 16.7 meters, the configured change threshold can be x.

Taking the LTE system as an example, the content of step 301 will be described. In the LTE system, the base station may send an RRC connection reconfiguration message to the UE, where the RRC connection reconfiguration message includes a measConfig cell, and the measConfig cell is used to configure measurement configuration information. In this embodiment, in addition to the existing measurement configuration information, the measConfig cell adds a new report trigger condition, that is, a signal change trigger condition, and the UE can trigger the measurement report only when the signal change trigger condition is satisfied. The signal change trigger condition, for example, may include a change threshold and/or a monitoring period. The signal change trigger condition can be at the band level, that is, one frequency band corresponds to one signal change trigger condition. The signal change triggering condition may also be a more detailed cell level, that is, some cells in a frequency band may be configured with a signal change trigger condition, and some may not be configured. For a cell configured with a signal change trigger condition, different change thresholds may be configured. And monitoring time.

For the operation performed by the UE according to the measurement configuration information, reference may be made to the description of the embodiment shown in FIG. 1B and FIG. 2A, and details are not described herein again.

After transmitting the measurement configuration information to the UE, the base station receives the measurement report reported by the UE. In this embodiment, the measurement report received by the base station is generated and sent by the UE after determining that the neighboring cell satisfies the signal change trigger condition according to the measurement result of the neighboring cell.

After receiving the measurement report reported by the UE, the UE may perform mobility management on the UE, for example, control the UE to perform cell handover, or configure the cell that triggers the measurement report to be Scel. That is, in this embodiment, the base station determines, according to the measurement report reported by the UE, whether the UE performs handover to the neighboring cell.

In this embodiment, the UE reports the measurement report only when the wireless signal receiving strength of the neighboring cell or the wireless signal receiving quality in the monitoring period is less than the change threshold, that is, only when the UE is considered to be in a low-speed motion state or a stationary state. The measurement report is reported, and the base station only receives the measurement report sent by the UE in the low-speed motion state or the stationary state, and then reports the measurement report. Compared with the prior art, the UE solves the problem that the UE in the prior art frequently performs cell handover in the medium and high-speed mobile scenarios, and is beneficial to reducing the mobility management of the UE by the base station based on the measurement report. Unnecessary switching caused by the process is conducive to saving network resources and reducing business interruptions, thereby improving the user experience.

FIG. 4 is a flowchart of still another measurement method according to an embodiment of the present invention. As shown in Figure 4, the method includes:

401. The UE receives the measurement configuration information sent by the base station, where the measurement configuration information includes signal change monitoring indication information, where the signal change monitoring indication information is used to indicate that the UE monitors and reports the signal change of the neighboring cell in the monitoring period. Monitored signal change information.

In this embodiment, the measurement configuration information sent by the base station to the UE not only indicates that the UE performs measurement on the neighboring cell, but also needs to control the UE to frequently perform cell handover when the base station performs mobility management on the UE according to the report of the measurement report. The measurement configuration information sent by the base station to the UE further includes signal change monitoring indication information, which is used to indicate that the UE monitors the signal change of the neighboring cell and reports the monitored signal change information during the monitoring period, so that the base station can learn the neighboring cell. The signal changes in order to facilitate the mobility management of the UE based on the signal changes of the neighboring cells.

In this embodiment, the monitoring period and the signal change information in the signal change monitoring indication information may be flexibly configured by the base station according to the application scenario. For example, the base station can be configured with the monitoring period as the cell level parameter, that is, the monitoring period in the signal change monitoring indication information corresponding to different cells of the same working frequency band can be different. For another example, the base station may configure the monitoring period as the frequency band level parameter, that is, the monitoring period in the signal change monitoring indication information corresponding to the cell in the different working frequency band may be different. The working frequency band can be a carrier. Alternatively, parameters such as a monitoring period and signal change information in the signal change monitoring indication information may also be specified by an agreement.

The radio signal receiving strength of the neighboring cell may be RSRP or RCPI, but is not limited thereto. The radio signal reception quality of the neighboring cell may be RSRQ or RSNI, but is not limited thereto. Among them, RCPI is mainly used to reflect the signal strength of the WiFi channel; RSNI is mainly used to reflect the interference of the WiFi channel.

It is noted herein that the monitoring period in the signal change monitoring indication information may be determined by the coverage range of the neighboring cell. Generally, the coverage of the neighboring cell is larger, and the monitoring period is longer.

Taking the LTE system as an example, the related content of step 401 will be described. In the LTE system, the base The station may send an RRC Connection Reconfiguration message to the UE, the RRC Connection Reconfiguration message including a measConf ig cell, which is used to configure measurement configuration information. In this embodiment, in addition to the existing measurement configuration information, the measConf ig cell adds a signal change monitoring indication information, and the UE needs to monitor the signal change of the neighboring cell according to the signal change monitoring indication information and report the monitored signal. Change information. The signal change monitoring indication information may include, for example, a monitoring period. The signal change monitoring indication information may be at the frequency band level, that is, one frequency band corresponds to one signal change monitoring indication information. The signal change monitoring indication information may also be a more detailed cell level, that is, some cells in a frequency band may be configured with signal change monitoring indication information, and some may not be configured. For a cell configured with signal change monitoring indication information, different configurations may be configured. Monitoring period.

402. The UE performs, according to the measurement configuration information, a signal of the neighboring cell.

After receiving the measurement configuration information sent by the base station, the UE measures the signal of the neighboring cell according to the indication of the measurement configuration information. The neighboring cells may include, but are not limited to, a micro cell (Pico cel l ), a small cell (smal l cel l ), a WiFi AP, and a macro cell.

403. The UE monitors the indication information according to the signal, monitors, in the monitoring period, a signal change of the neighboring cell, and after the monitoring period, generates a measurement report and monitors the neighboring cell that is monitored. Signal change information is carried in the measurement report and sent to the base station.

Specifically, the UE monitors a signal change of the neighboring cell in a monitoring period specified by the signal change monitoring indication information, and specifically monitors a signal change of the neighboring cell according to the measurement result of the neighboring cell in the monitoring period, and ends at the monitoring period. Then, the measurement report is generated and the signal change information monitored during the monitoring period is carried in the measurement report and reported to the base station. The measurement report includes a cell (possibly one or more) that triggers the measurement report, and information such as a radio signal reception strength or a radio signal reception quality of the cell. Further, the measurement report of this embodiment further includes signal change information of the neighboring cell of the monitored trigger measurement report, where the signal change information includes a wireless signal reception strength of the neighboring cell or a change of the wireless signal reception quality in the monitoring period. range. Specifically, the signal change information of the neighboring cell may be, for example, a difference between a maximum value and a minimum value of a wireless signal receiving strength or a wireless signal receiving quality of the neighboring cell monitored during the monitoring period, that is, a wireless signal receiving strength. The difference between the maximum value and the minimum value, or may be the difference between the maximum value and the minimum value of the wireless signal reception quality. Alternatively, the signal change information of the neighboring cell may be, for example, a maximum value and a minimum value of the wireless signal receiving strength or the wireless signal receiving quality of the neighboring cell monitored during the monitoring period, that is, the wireless signal receiving strength of the neighboring cell may be the maximum. Value and minimum, or The maximum and minimum values of the wireless signal reception quality of the neighboring cells.

In an optional implementation manner, the measurement configuration information further includes a report triggering condition, configured to indicate that the UE performs the reporting of the measurement report when the report triggering condition is met. Based on this, the method further includes: determining, by the UE, that the neighboring cell meets the report triggering condition. For example, in an alternative embodiment of the embodiment shown in Figure 4, the report trigger condition includes a signal strength/quality trigger condition. The signal strength/quality trigger condition is that the radio signal reception strength of the neighboring cell or the radio signal reception quality always meets the specified threshold within the time to Trigger. Based on this, the process of determining, by the UE, that the neighboring cell meets the report triggering condition includes: determining, by the UE, whether the wireless signal receiving strength of the neighboring cell or the wireless signal receiving quality meets the specified threshold in the triggering time, if the determination result is If yes, it is determined that the neighboring cell satisfies the report triggering condition; if the determining result is no, it is determined that the neighboring cell does not satisfy the report triggering condition.

Based on the report triggering condition, the monitoring period is: a period of time from when the user equipment determines that the neighboring cell satisfies the report triggering condition. Or the monitoring period is: a period of time when the user equipment determines that the neighboring cell meets the report triggering condition.

In an optional implementation manner of the embodiment shown in FIG. 4, the start timing of monitoring the signal change of the neighboring cell by the UE may be divided into two types, which are separately described below.

One way is to start signal change monitoring when it is determined that the neighboring cell satisfies the above-mentioned report triggering condition or when it is determined that the neighboring cell satisfies the above-mentioned report triggering condition. Based on this, an implementation manner of step 403 includes: determining, by the UE, whether the neighboring cell meets the report triggering condition, and after determining that the neighboring cell meets the report triggering condition, generating the measurement report, and according to the Signal change monitoring indication information, monitoring a signal change of the neighboring cell during the monitoring period, and carrying signal change information of the neighboring cell monitored in the monitoring period in the measurement report and sending the signal to the base station . In this implementation manner, the monitoring period is: a period of time since the UE determines that the neighboring cell meets the report triggering condition.

The specific process of the foregoing implementation manner may be: the UE determines whether the neighboring cell meets the report triggering condition, and when determining that the neighboring cell satisfies the report triggering condition, the signal change monitoring is started, and the signal change monitoring timer is started, and the timing duration is The monitoring period in the signal change monitoring indication information, after the timer expires, triggering generation and reporting of the measurement report, where the measurement report carries signal change information of the neighboring cell monitored by the timer device. The signal reported here is changed The information may be the difference between the wireless signal receiving strength of the neighboring cell or the maximum value of the wireless signal receiving quality and the minimum value of the signal, or may be the wireless signal receiving strength of the neighboring cell or the maximum and minimum values of the wireless signal receiving quality. The advantage of this implementation is that the UE only needs to perform simple function expansion on the basis of implementing the existing report trigger condition, because it is a function of expanding the indication for the signal change monitoring indication information after implementing the existing report trigger condition function. Therefore, there is no need to modify the functions that implement the existing report trigger conditions, and the implementation is simple.

Alternatively, monitoring of signal changes to neighboring cells is initiated during measurement of neighboring cells, and signal change information of neighboring cells monitored over a period of time is stored. Based on this, an implementation manner of step 403 includes: monitoring, by the UE, monitoring indication information according to the signal, monitoring a signal change of the neighboring cell in the monitoring period, and determining whether the neighboring cell meets the report triggering condition And determining, when the neighboring cell meets the report triggering condition, the measurement report, and carrying the signal change information of the neighboring cell monitored in the monitoring period in the measurement report, and sending the signal to the base station . In this implementation manner, the monitoring period is: a period of time until the UE determines that the neighboring cell meets the report triggering condition, that is, a period of time for storing signal change information monitored to the neighboring cell.

The specific process of the foregoing implementation manner may be: the UE starts monitoring the signal change of the neighboring cell during the measurement of the neighboring cell, and saves the signal change information of the neighboring cell monitored within a period of time, when the neighboring cell satisfies the report. After the trigger condition is met, the measurement report is generated and reported immediately, and the signal change information of the previously saved neighboring cell is carried in the measurement report. The advantage of this implementation is that the radio signal reception strength or the radio signal reception quality of the neighboring cell is monitored before determining that the neighboring cell satisfies the report trigger condition, and once the neighboring cell is determined to meet the report trigger condition, the previously monitored radio can be directly used. The range of change of the signal receiving strength or the receiving quality of the wireless signal is compared with the change threshold, and the measurement report is reported according to the comparison result in time, since it is not necessary to wait for the wireless signal receiving strength or wireless to the neighboring cell after determining that the neighboring cell satisfies the reporting trigger condition Monitoring of signal reception quality, reporting report reporting delay is small.

For this mode, the monitoring period can be less than or equal to the duration of the triggering time. Preferably, the length of the monitoring period may be equal to the duration of the triggering time, that is, when the timer corresponding to the triggering time is started, the signal change monitoring is started. This method can simplify the implementation of the UE and has less impact on the standard.

It is noted that, in various implementations or situations of the embodiment, the signal change information carried in the measurement report reported by the UE may be that the wireless signal received by the neighboring cell monitored during the monitoring period is strong. The maximum value and the minimum value of the degree, or the maximum and minimum values of the wireless signal receiving quality, may also be the difference between the maximum value and the minimum value of the wireless signal receiving quality, or the maximum and minimum values of the wireless signal receiving intensity. The difference can also be the rate of change of the signal, that is, the value of the signal change per unit time.

It is noted that, in this embodiment, the signal change information carried by the measurement report is mainly used by the base station to determine whether to switch the UE to the neighboring cell.

It can be seen that, in this embodiment, the UE performs measurement on the neighboring cell according to the measurement configuration information sent by the base station, and monitors the indication information according to the signal change carried in the measurement configuration information, and changes the signal of the adjacent cell in the specified monitoring period. The monitoring is performed, and when the neighboring cell satisfies the report triggering condition in the measurement configuration information, the monitored signal change information is carried in the measurement report and reported to the base station, so that the base station can perform mobility on the UE according to the signal change information carried in the measurement report. Management, for example, if the signal change information carried in the measurement report indicates that the signal change of the neighboring cell that triggers the measurement report is less than a certain value, if the UE moves at a slower speed or does not move, then perform cell handover or increase the cell that triggers the measurement report. As a SCel l or the like, the cell handover is not performed or the SCel l is added. Compared with the prior art, the problem that the UE in the prior art is frequently performing cell handover in a medium or high-speed mobile scenario is solved, which is advantageous for reducing mobility. Unnecessary switching during management Help conserve network resources, reduce business interruption, thereby improving the user experience.

FIG. 5 is a flowchart of another measurement control method according to an embodiment of the present invention. As shown in FIG. 5, the method includes:

501. The base station sends measurement configuration information to the UE, where the measurement configuration information includes signal change monitoring indication information, where the signal change monitoring indication information is used to indicate that the UE monitors and reports the signal change of the neighboring cell in the monitoring period. Signal change information to.

502. The base station receives the measurement report sent by the UE, where the measurement report is that the UE measures, according to the measurement configuration information, a signal of the neighboring cell, and generates and sends the signal after the monitoring period, where the measurement report carries the UE. The signal change information of the neighboring cell monitored in the monitoring period according to the signal change monitoring indication information; wherein the signal change information of the neighboring cell includes a wireless signal receiving strength or a wireless signal of the neighboring cell The range of variation of the reception quality during the monitoring period. In this embodiment, the measurement configuration information sent by the base station to the UE not only indicates that the UE performs measurement on the neighboring cell, but also needs to control the UE to frequently perform cell handover when the base station performs mobility management on the UE according to the report of the measurement report. The measurement configuration information sent by the base station to the UE further includes signal change monitoring indication information, which is used to indicate that the UE monitors the signal change of the neighboring cell and reports the monitored signal change information during the monitoring period, so that the base station can learn the neighboring cell. The signal changes in order to facilitate the mobility management of the UE based on the signal changes of the neighboring cells.

Taking the LTE system as an example, the related content of step 501 will be described. In the LTE system, the base station may send an RRC connection reconfiguration message to the UE, where the RRC connection reconfiguration message includes a measConf ig cell, and the measConfig cell is used to configure measurement configuration information. In this embodiment, in addition to the existing measurement configuration information, the measConf ig cell adds a signal change monitoring indication information, and the UE needs to monitor the signal change of the neighboring cell according to the signal change monitoring indication information and report the monitored signal. Change information. The signal change monitoring indication information may include, for example, a monitoring period. The signal change monitoring indication information may be at the frequency band level, that is, one frequency band corresponds to one signal change monitoring indication information. The signal change monitoring indication information may also be a more detailed cell level, that is, some cells in a frequency band may be configured with signal change monitoring indication information, and some may not be configured. For a cell configured with signal change monitoring indication information, different configurations may be configured. Monitoring period. Further, the measurement configuration information further carries a report triggering condition, which is used to indicate that the UE reports the measurement report when the report trigger condition is met. Based on the report triggering condition, the monitoring period is: a period of time from when the user equipment determines that the neighboring cell satisfies the report triggering condition. Or the monitoring period is: a period of time when the user equipment determines that the neighboring cell meets the report triggering condition.

For the operation performed by the UE according to the measurement configuration information, refer to the description of the embodiment shown in FIG. 4, and details are not described herein again.

After transmitting the measurement configuration information to the UE, the base station receives the measurement report reported by the UE. In this embodiment, the measurement report received by the base station carries signal change information of the neighboring cell monitored by the UE during the monitoring period, where the signal change information includes the wireless signal receiving strength of the neighboring cell or the wireless signal receiving quality in the monitoring. The range of variation within the time period. Specifically, the signal change information of the neighboring cell may be, for example, a difference between a maximum value and a minimum value of a wireless signal receiving strength or a wireless signal receiving quality of the neighboring cell monitored during the monitoring period, that is, a wireless signal receiving strength. The difference between the maximum value and the minimum value, or may be the difference between the maximum value and the minimum value of the wireless signal reception quality. Alternatively, the signal change information of the neighboring cell may be, for example, a maximum value and a minimum value of the wireless signal receiving strength or the wireless signal receiving quality of the neighboring cell monitored during the monitoring period, that is, the wireless signal receiving strength of the neighboring cell may be the maximum. The value and the minimum value, or the maximum and minimum values of the radio signal reception quality of the neighboring cells.

Further, after receiving the measurement report reported by the UE, the base station may further perform mobility management on the UE according to the signal change information of the neighboring cell in the measurement report. For example, if the signal change information carried in the measurement report indicates that the signal change of the neighboring cell that triggers the measurement report is less than a certain value, the UE is considered to be slow or not moving, and then the base station controls the UE to perform cell handover or increase triggering the measurement report.
