Method, apparatus and terminal for processing measurement event, and chip

Abstract

The application provides a processing method and device for measuring events, a terminal and a chip, and belongs to the field of communication technology. The method comprises the following steps: in the case that the signal strength of a target service cell is greater than a speed threshold, modifying the event triggering condition of a first A2 event and / or a second A2 event; in the case that the terminal has reported the first A2 event to a network device and received the measurement configuration information issued by the network device, modifying the measurement configuration information. The above-mentioned scheme not only increases the event reporting interval of the first A2 event and the second A2 event, but also speeds up the reporting process of the neighbor cell measurement event triggered after the first A2 event is reported, so as to ensure that the reporting time of the neighbor cell measurement event is earlier than that of the second A2 event, thereby enabling the terminal to successfully switch to a neighbor cell, avoiding the business confusion caused by the blind redirection due to the incomplete reporting of the neighbor cell measurement event and the reporting of the second A2 event, and thus improving the user experience.

Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method, apparatus, terminal and chip for processing measurement events. Background Technology

[0002] With the development of communication technology, network devices typically configure multiple identical measurement events for terminals. Taking the A2 event as an example, the A2 event is the measurement event reported by the terminal to the network device when it measures that the signal strength of the serving cell is below a certain threshold.

[0003] In related technologies, the network device allocates multiple A2 events to the terminal, including a first A2 event and a second A2 event, where the trigger threshold of the first A2 event is higher than that of the second A2 event. When the signal strength of the terminal's serving cell decreases below the trigger threshold of the first A2 event, the terminal can perform neighbor cell measurements based on the measurement configuration information issued by the network device, enabling the terminal to promptly switch to a neighboring cell with a higher signal strength when the signal strength of the serving cell decreases. When the signal strength decreases below the trigger threshold of the second A2 event, the network device can release the radio connection between the terminal and the serving cell and instruct the terminal to perform blind redirection.

[0004] However, when the signal strength of the serving cell suddenly drops, the terminal may be instructed by the network device to perform blind redirection before it can switch to a neighboring cell with a stronger signal due to the reporting of the first A2 event. Furthermore, since the network device assigns a blind cell to the terminal during blind redirection, the terminal may be unable to successfully camp, which greatly prolongs the interruption time of the terminal's services and seriously affects the user experience. Summary of the Invention

[0005] This application provides a method, apparatus, terminal, and chip for processing measurement events. It increases the reporting interval between the first A2 event and the second A2 event, and accelerates the reporting process of neighboring cell measurement events triggered after the first A2 event is reported. This ensures that the reporting time of the neighboring cell measurement event is earlier than the reporting time of the second A2 event, enabling the terminal to successfully switch to a neighboring cell. It avoids blind redirection caused by the second A2 event being reported before the neighboring cell measurement event reporting is completed, thus preventing service disruption and improving user experience. The technical solution is as follows:

[0006] According to one aspect of the embodiments of this application, a method for processing measurement events is provided, the measurement events including a first A2 event and a second A2 event, wherein the trigger threshold value of the first A2 event is higher than that of the second A2 event, the method comprising:

[0007] If the signal strength fading rate of the target serving cell is greater than the rate threshold, modify the event triggering conditions of the first A2 event and / or the second A2 event to increase the time interval between the reporting time of the first A2 event and the reporting time of the second A2 event, wherein the target serving cell is the serving cell where the terminal is currently camped.

[0008] When the terminal has reported the first A2 event to the network device and received the measurement configuration information issued by the network device, the measurement configuration information is modified so that the reporting time of the neighbor cell measurement event indicated by the modified measurement configuration information is earlier than the reporting time of the second A2 event. The neighbor cell measurement event is used to indicate the measurement of the neighbor cells of the target serving cell based on the measurement configuration information.

[0009] According to another aspect of the embodiments of this application, a processing apparatus for measurement events is provided, the measurement events including a first A2 event and a second A2 event, wherein the trigger threshold value of the first A2 event is higher than that of the second A2 event, the apparatus comprising:

[0010] The first modification module is used to modify the event triggering conditions of the first A2 event and / or the second A2 event when the fading rate of the signal strength of the target serving cell is greater than the rate threshold, so as to increase the time interval between the reporting time of the first A2 event and the reporting time of the second A2 event, wherein the target serving cell is the serving cell where the terminal is currently camped.

[0011] The second modification module is used to modify the measurement configuration information when the terminal has reported the first A2 event to the network device and received the measurement configuration information issued by the network device, so that the reporting time of the neighbor cell measurement event indicated by the modified measurement configuration information is earlier than the reporting time of the second A2 event. The neighbor cell measurement event is used to indicate the measurement of the neighbor cells of the target serving cell based on the measurement configuration information.

[0012] In some embodiments, the event triggering condition includes a trigger threshold and a trigger time. The trigger threshold is used to indicate the signal strength of the target serving cell when the first A2 event or the second A2 event is reported. The trigger time is used to indicate the duration after the trigger threshold of the first A2 event or the second A2 event is met.

[0013] The first modification module includes:

[0015] The second modification unit is used to lower the trigger threshold value of the second A2 event and / or extend the trigger time of the second A2 event so as to delay the reporting time of the second A2 event.

[0016] In some embodiments, the first modification unit is configured to determine at least one of a first threshold offset value and a first time offset value based on the signal strength of the target serving cell, the fading rate of the signal strength, and the event triggering condition of the first A2 event. The first threshold offset value is positively correlated with the difference between the signal strength and the triggering threshold value of the first A2 event and the fading rate, and the first time offset value is positively correlated with the triggering time of the first A2 event and the fading rate. The modification unit is configured to increase the triggering threshold value of the first A2 event by the first threshold offset value and / or shorten the triggering time of the first A2 event by the first time offset value.

[0017] In some embodiments, the second modification unit is configured to determine at least one of a second threshold offset value and a second time offset value based on the fading rate of the signal strength, the event triggering condition of the second A2 event, and the event triggering condition of the first A2 event. The second threshold offset value is negatively correlated with the difference between the triggering threshold value of the second A2 event and the triggering threshold value of the first A2 event, and positively correlated with the fading rate. The second time offset value is negatively correlated with the triggering time of the second A2 event and positively correlated with the fading rate. The modification unit further modifies the triggering threshold value of the second A2 event by decreasing the second threshold offset value and / or extends the triggering time of the second A2 event by increasing the second time offset value.

[0018] In some embodiments, the second modification module is configured to determine the predicted reporting time of the second A2 event based on the signal strength of the target serving cell, the fading rate of the signal strength, and the event triggering conditions of the modified second A2 event; and to modify the measurement configuration information when the time interval between the predicted reporting time of the second A2 event and the reporting time of the first A2 event is less than a duration threshold, and the terminal has reported the first A2 event to the network device and received the measurement configuration information issued by the network device.

[0019] In some embodiments, the measurement configuration information includes the neighboring cell measurement event, the event triggering condition of the neighboring cell measurement event, and the measurement period of the neighboring cell measurement event. The event triggering condition includes a first triggering threshold, a second triggering threshold, and a triggering time. The first triggering threshold is used to indicate the signal strength of the target serving cell when the neighboring cell measurement event is triggered to be reported. The second triggering threshold is used to indicate the signal strength of the neighboring cells of the target serving cell when the neighboring cell measurement event is triggered to be reported. The triggering time is used to indicate the duration after the first triggering threshold and the second triggering threshold of the neighboring cell measurement event are met.

[0020] The second modification module is used to increase the first trigger threshold value, and / or decrease the second trigger threshold value, and / or shorten the trigger time, and / or shorten the measurement cycle of the neighboring cell measurement event, so as to advance the reporting time of the neighboring cell measurement event.

[0021] In some embodiments, the second modification module is configured to determine at least one of a third threshold offset value, a fourth threshold offset value, a third time offset value, and a period offset value based on the signal strength of the target serving cell, the fading rate of the signal strength, and the event triggering condition of the neighboring cell measurement event. The third threshold offset value is positively correlated with the difference between the signal strength and the first trigger threshold value and the fading rate; the fourth threshold offset value is positively correlated with the second trigger threshold value and the fading rate; the third time offset value is positively correlated with the triggering time of the neighboring cell measurement event and the fading rate; and the period offset value is positively correlated with the measurement period of the neighboring cell measurement event and the fading rate. The module may also increase the first trigger threshold value by increasing the third threshold offset value, and / or decrease the second trigger threshold value by decreasing the fourth threshold offset value, and / or shorten the triggering time by decreasing the third time offset value, and / or shorten the measurement period by decreasing the period offset value.

[0022] In some embodiments, if the triggering time of the second A2 event is not extended when the event triggering condition of the second A2 event is modified, the apparatus further includes:

[0023] The first determining module is used to determine the predicted reporting time of the second A2 event based on the current time and the triggering time of the second A2 event when the terminal is measuring the neighboring cells of the target serving cell based on the modified measurement configuration information, if the signal strength of the target serving cell is less than the trigger threshold value after the second A2 event is reduced.

[0024] The second determining module is used to determine the predicted reporting time of the neighboring cell measurement event based on the reporting time of the first A2 event and the modified measurement configuration information;

[0025] The extension module is used to extend the triggering time of the second A2 event when the predicted reporting time of the second A2 event is earlier than the predicted reporting time of the neighboring cell measurement event.

[0026] In some embodiments, the measurement configuration information includes the neighboring cell measurement event, the event triggering condition of the neighboring cell measurement event, the measurement period of the neighboring cell measurement event, and the neighboring cell list of the target serving cell. The apparatus further includes:

[0027] The measurement module is used to measure multiple neighboring cells in the neighboring cell list based on the measurement period in the modified measurement configuration information, and to obtain the measurement results of the neighboring cell measurement events. The measurement results are used to indicate the signal strength of the multiple neighboring cells.

[0028] The reporting module is used to report the measurement results of the neighboring cell measurement event to the network device when the measurement results meet the event triggering conditions of the neighboring cell measurement event. The network device is used to issue a handover command to the terminal based on the measurement results.

[0029] A handover module is used to, in response to the handover command, switch from the target serving cell to a neighboring cell indicated by the handover command.

[0030] According to another aspect of the embodiments of this application, a terminal is provided, the terminal including a processor, a memory, and a transceiver; the memory stores at least one piece of program code, the at least one piece of program code being executed by the processor to implement the measurement event processing method as described above.

[0031] According to another aspect of the embodiments of this application, a chip is provided, the chip including programmable logic circuits and / or program instructions, which, when the chip is run on a terminal, are used to implement the measurement event processing method described above.

[0032] This application provides a method for handling measurement events. When a first A2 event and a second A2 event are triggered due to a sudden drop in the signal strength of the terminal's serving cell, the terminal can modify the event triggering conditions of the first A2 event and / or the second A2 event to increase the reporting interval between the first A2 event and the second A2 event, thereby reserving sufficient time for the terminal to perform subsequent neighbor cell measurements. Simultaneously, after the first A2 event is reported, the terminal can also modify the measurement configuration information issued by the network device to accelerate the reporting process of neighbor cell measurement events triggered after the first A2 event, ensuring that the reporting time of the neighbor cell measurement event is earlier than the reporting time of the second A2 event. This allows the terminal to receive the handover instruction issued by the network device before the second A2 event is reported, enabling it to switch to a neighbor cell with a better signal. This avoids blind redirection caused by the reporting of the second A2 event before the neighbor cell measurement event is completed, which could lead to service disruption and improve user experience.

[0048] Figure 2 This is a flowchart of a method for processing measurement events provided in an embodiment of this application. The method is executed by a terminal; see [link to relevant documentation]. Figure 2 The method includes:

[0049] 201. If the signal strength fading rate of the target serving cell is greater than the rate threshold, modify the event triggering conditions of the first A2 event and / or the second A2 event to increase the time interval between the reporting time of the first A2 event and the reporting time of the second A2 event, and the target serving cell is the serving cell where the terminal is currently camped.

[0050] In this embodiment, the A2 event is used to indicate that the signal strength of the serving cell currently in which the terminal is camped is lower than a threshold value. In other words, the A2 event is a measurement event reported by the terminal to the network device when it measures that the signal strength of the serving cell is lower than the threshold value. The terminal is configured with multiple A2 events, and the triggering conditions for each A2 event are different. These multiple A2 events include a first A2 event with a higher trigger threshold value and a second A2 event with a lower trigger threshold value; that is, the triggering threshold value of the first A2 event is higher than that of the second A2 event.

[0051] For the first A2 event, when the signal strength of the terminal's serving cell decreases, the signal strength will first decrease to below the trigger threshold of the first A2 event, meaning the terminal will first report the first A2 event to the network device. After receiving the first A2 event, the network device can send measurement configuration information to the terminal. The terminal can perform neighbor cell measurements based on this measurement configuration information and report the measurement results to the network device, so that the network device can issue a handover command to the terminal based on the measurement results. The handover command is used to instruct the terminal to switch from its currently serving cell to a neighboring cell with a higher signal strength.

[0052] For the second A2 event, when the signal strength of the serving cell drops below the trigger threshold of the second A2 event, it indicates that the signal of the serving cell is extremely poor and the neighbor cell measurement process triggered by the first A2 event was not successfully executed by the terminal, meaning the terminal failed to successfully hand over to a neighboring cell. At this time, after receiving the second A2 event reported by the terminal, the network device can release the radio connection between the terminal and the serving cell and instruct the terminal to perform a blind redirection, so that the terminal can camp on the cell blindly assigned to it by the network device.

[0053] In this embodiment, the target serving cell is the serving cell where the terminal is currently camped. When the signal strength fading rate of the target serving cell exceeds a certain threshold, it indicates a sudden drop in the signal strength of the serving cell where the terminal is currently camped (e.g., the terminal is on a high-speed train, subway, or in a fast-moving scenario). When the signal strength drops sharply, the terminal triggers the reporting of a first A2 event and a second A2 event. However, during the event reporting process, the terminal's configuration of the A2 event triggering conditions may be unreasonable, leading to an excessively short reporting interval between the first and second A2 events. This results in the terminal being instructed by the network device to perform a blind redirect triggered by the second A2 event before completing the neighbor cell measurement process triggered by the first A2 event report. In other words, the terminal cannot complete the handover from the target serving cell to a neighboring cell before the second A2 event is reported, even when the signal strength of the serving cell drops sharply. Furthermore, since the cell allocated to the terminal by the network device during blind redirection is blindly allocated, it is highly likely that the terminal will fail to camp successfully, significantly prolonging the interruption time of terminal services and severely impacting user experience.

[0054] To address the aforementioned issues, when the signal strength of the target serving cell suddenly drops, the terminal can modify the event triggering conditions of the first A2 event and / or the second A2 event to increase the time interval between the reporting time of the first A2 event and the reporting time of the second A2 event. This increases the event reporting interval between the first A2 event and the second A2 event, thereby allowing sufficient time for the terminal to perform subsequent neighbor cell measurements.

[0055] 202. If the terminal has reported the first A2 event to the network device and received the measurement configuration information issued by the network device, modify the measurement configuration information so that the reporting time of the neighbor cell measurement event indicated by the modified measurement configuration information is earlier than the reporting time of the second A2 event. The neighbor cell measurement event is used to indicate the measurement of the neighbor cells of the target serving cell based on the measurement configuration information.

[0056] In this embodiment, when the signal strength of the target serving cell drops below the trigger threshold of the first A2 event, the terminal reports the first A2 event to the network device. Correspondingly, the network device sends measurement configuration information to the terminal for performing neighbor cell measurements. The measurement configuration information includes neighbor cell measurement events configured by the network device for the terminal and measurement configurations related to these events. The neighbor cell measurement events instruct the terminal to measure the neighbor cells of the target serving cell based on the measurement configurations in the measurement configuration information. After the event triggering condition of the neighbor cell measurement event is met during the measurement process, the terminal can report the neighbor cell measurement event to the network device, that is, report the measurement results obtained from the neighbor cell measurement.

[0057] In order to enable the terminal to complete the reporting of neighbor cell measurement events before the reporting of the second A2 event during the process of a sudden drop in the signal strength of the target serving cell, the terminal can also modify the measurement configuration information to speed up the neighbor cell measurement process triggered after the reporting of the first A2 event, so that the reporting time of the neighbor cell measurement event indicated by the modified measurement configuration information is earlier than the reporting time of the second A2 event.

[0058] This application provides a method for handling measurement events. When a first A2 event and a second A2 event are triggered due to a sudden drop in the signal strength of the terminal's serving cell, the terminal can modify the event triggering conditions of the first A2 event and / or the second A2 event to increase the reporting interval between the first A2 event and the second A2 event, thereby reserving sufficient time for the terminal to perform subsequent neighbor cell measurements. Simultaneously, after the first A2 event is reported, the terminal can also modify the measurement configuration information issued by the network device to accelerate the reporting process of neighbor cell measurement events triggered after the first A2 event, ensuring that the reporting time of the neighbor cell measurement event is earlier than the reporting time of the second A2 event. This allows the terminal to receive the handover instruction issued by the network device before the second A2 event is reported, enabling it to switch to a neighbor cell with a better signal. This avoids blind redirection caused by the reporting of the second A2 event before the neighbor cell measurement event is completed, which could lead to service disruption and improve user experience.

[0059] Figure 3 This is a flowchart of another method for processing measurement events provided in an embodiment of this application. This method is executed by a terminal; see [link to relevant documentation]. Figure 3 The method includes:

[0060] 301. When the signal strength fading rate of the target serving cell is greater than the rate threshold, increase the trigger threshold of the first A2 event and / or shorten the trigger time of the first A2 event to advance the reporting time of the first A2 event; and / or decrease the trigger threshold of the second A2 event and / or extend the trigger time of the second A2 event to delay the reporting time of the second A2 event.

[0061] In this embodiment, the A2 event is used to indicate that the signal strength of the serving cell currently in which the terminal is camped is lower than a threshold value. That is, the A2 event is a measurement event reported by the terminal to the network device when it measures that the signal strength of the serving cell is lower than the threshold value. The network device is a communication device, such as a base station, that enables the terminal to access the Internet and covers multiple cells. The terminal can access the wireless network by accessing any cell covered by the network device. The terminal is configured with multiple A2 events, and the triggering conditions for each A2 event are different. These multiple A2 events include a first A2 event with a higher trigger threshold value and a second A2 event with a lower trigger threshold value; that is, the triggering threshold value of the first A2 event is higher than that of the second A2 event.

[0062] When there is only one first A2 event, for this first A2 event, when the signal strength of the terminal's serving cell decreases to below the trigger threshold of the first A2 event, the terminal can report the first A2 event to the network device. After receiving the first A2 event, the network device can send measurement configuration information to the terminal. The terminal can perform neighbor cell measurements based on the measurement configuration information and report the measurement results to the network device, so that the network device can issue a handover command to the terminal based on the measurement results. The handover command is used to instruct the terminal to hand over from the currently camped serving cell to a neighbor cell with a higher signal strength. Neighbor cell measurements can be intra-system measurements or inter-system measurements. Intra-system measurements refer to measurements of neighbor cells within the communication system to which the serving cell belongs, while inter-system measurements refer to measurements of neighbor cells within other communication systems besides the communication system to which the serving cell belongs. Accordingly, the neighbor cell indicated by the handover command can be a cell within the communication system to which the serving cell belongs, or a cell within another communication system besides the communication system to which the serving cell belongs.

[0063] When there are multiple first A2 events, these events can include first A2 events that trigger intra-system measurements after reporting and first A2 events that trigger inter-system measurements after reporting. The trigger threshold for the first A2 event corresponding to intra-system measurements is higher than that for the first A2 event corresponding to inter-system measurements.

[0064] In summary, regardless of whether there are one or more first A2 events, for first A2 events corresponding to intra-system measurements, when the signal strength of the serving cell decreases below the trigger threshold for the first A2 event corresponding to intra-system measurements, the terminal will report the first A2 event to the network device and then perform intra-system measurements according to the measurement configuration information issued by the network device. For first A2 events corresponding to inter-system measurements, when the signal strength of the serving cell decreases below the trigger threshold for the first A2 event corresponding to inter-system measurements, the terminal will report the first A2 event to the network device and then perform inter-system measurements according to the measurement configuration information issued by the network device.

[0065] For the second A2 event, when the signal strength of the serving cell drops below the trigger threshold of the second A2 event, it indicates that the signal of the serving cell is extremely poor and the neighbor cell measurement process triggered by the first A2 event was not successfully executed by the terminal, meaning the terminal failed to successfully hand over to a neighboring cell. At this time, after receiving the second A2 event reported by the terminal, the network device can release the radio connection between the terminal and the serving cell and instruct the terminal to perform a blind redirection, so that the terminal can camp on the cell blindly assigned to it by the network device.

[0066] In this embodiment, the target serving cell is the serving cell where the terminal is currently camped. When the signal strength fading rate of the target serving cell exceeds a certain threshold, it indicates a sudden drop in the signal strength of the serving cell where the terminal is currently camped (e.g., the terminal is on a high-speed train, subway, or in a fast-moving scenario). When the signal strength drops sharply, the terminal triggers the reporting of a first A2 event and a second A2 event. However, during the event reporting process, the terminal's configuration of the A2 event triggering conditions may be unreasonable, leading to an excessively short reporting interval between the first and second A2 events. This results in the terminal being instructed by the network device to perform a blind redirect triggered by the second A2 event before completing the neighbor cell measurement process triggered by the first A2 event report. In other words, the terminal cannot complete the handover from the target serving cell to a neighboring cell before the second A2 event is reported, even when the signal strength of the serving cell drops sharply. Furthermore, since the cell allocated to the terminal by the network device during blind redirection is blindly allocated, it is highly likely that the terminal will fail to camp successfully, significantly prolonging the interruption time of terminal services and severely impacting user experience.

[0067] To address the aforementioned issue, when a sudden drop in the signal strength of the target serving cell leads to an excessively short reporting interval between the first A2 event and the second A2 event, the terminal can modify the event triggering conditions for the first A2 event and / or the second A2 event. The event triggering conditions include a trigger threshold and a trigger time. The trigger threshold indicates the signal strength of the target serving cell when the first or second A2 event is triggered, and the trigger time indicates the duration after the trigger threshold for the first or second A2 event is met. Since the reporting time of an A2 event is the time when the signal strength of the serving cell is less than the trigger threshold for the A2 event plus the trigger time of the A2 event, the terminal can increase the trigger threshold for the first A2 event and / or shorten the trigger time of the first A2 event to advance its reporting time. When the reporting time of the first A2 event is advanced, the time interval between the reporting times of the first A2 event and the second A2 event will also increase. Alternatively, the terminal can lower the trigger threshold of the second A2 event and / or extend the trigger time of the second A2 event to delay the reporting time of the second A2 event. With the reporting time of the second A2 event delayed, the time interval between the reporting times of the first A2 event and the second A2 event will also increase. Step 301 above, by raising the trigger threshold of the first A2 event and lowering the trigger threshold of the second A2 event, can accelerate the rate at which the signal strength of the serving cell decreases to below the trigger threshold of the first A2 event and slow down the rate at which the signal strength decreases to below the trigger threshold of the second A2 event. By shortening the trigger time of the first A2 event and extending the trigger time of the second A2 event, the reporting of the first A2 event can be accelerated when the trigger threshold of the first A2 event is met, while the reporting of the second A2 event is delayed when the trigger threshold of the second A2 event is met. This increases the event reporting interval between the first and second A2 events, allowing sufficient time for the terminal to perform subsequent neighbor cell measurements. This increases the probability of the terminal successfully switching to a neighbor cell in a weak network environment and reduces the probability of the terminal performing blind redirection.

[0068] In some embodiments, the terminal can modify the event triggering condition of the first A2 event based on the signal strength of the target serving cell, the fading rate of the signal strength, and the event triggering condition of the unmodified first A2 event. Accordingly, the terminal determines at least one of a first threshold offset value and a first time offset value based on the signal strength of the target serving cell, the fading rate of the signal strength, and the event triggering condition of the first A2 event. The first threshold offset value is positively correlated with the difference between the signal strength and the triggering threshold value of the first A2 event and the fading rate, and the first time offset value is positively correlated with the triggering time of the first A2 event and the fading rate. Then, the terminal can increase the triggering threshold value of the first A2 event by the first threshold offset value and / or shorten the triggering time of the first A2 event by the first time offset value. Specifically, regarding the first threshold offset value, the greater the difference between the signal strength and the trigger threshold value of the first A2 event, the slower the signal strength decreases to below the trigger threshold value of the first A2 event. Therefore, the terminal can increase the increase in the trigger threshold value of the first A2 event, which means increasing the first threshold offset value. Thus, the first threshold offset value is positively correlated with the difference between the signal strength and the trigger threshold value of the first A2 event. The greater the fading rate of the signal strength, the shorter the event reporting interval between the first A2 event and the second A2 event. To reduce the signal strength to below the trigger threshold value of the first A2 event as quickly as possible, the terminal can increase the increase in the trigger threshold value of the first A2 event, which means increasing the first threshold offset value. Therefore, the first threshold offset value is positively correlated with the fading rate. Regarding the first time offset value, the greater the trigger time of the first A2 event, the later the reporting time of the first A2 event. To report the first A2 event as quickly as possible, the terminal can increase the reduction in the trigger time, which means increasing the first time offset value. The greater the signal strength fading rate, the shorter the reporting interval between the first A2 event and the second A2 event. To report the first A2 event as quickly as possible, the terminal can increase the reduction in trigger time, i.e., increase the first time offset value. Therefore, the first time offset value is positively correlated with the trigger time and fading rate of the first A2 event. By adaptively adjusting the increase in the trigger threshold value and the reduction in the trigger time of the first A2 event based on the difference between the signal strength of the target serving cell and the trigger threshold value of the first A2 event, the signal strength fading rate, and the trigger time of the first A2 event, the reporting interval between the first A2 event and the second A2 event can be lengthened as much as possible. This increases the probability of the terminal successfully handing over to a neighboring cell in a weak network environment and reduces the probability of the terminal performing blind redirection.

[0069] For example, if the trigger threshold for the first A2 event is -90 dBm and the first threshold offset is 2 dBm, then the increased trigger threshold for the first A2 event is -88 dBm. If the trigger time for the first A2 event is 160 ms and the first time offset is 60 ms, then the shortened trigger time for the first A2 event is 100 ms.

[0070] In some embodiments, the terminal can determine whether the signal strength of the target serving cell has suddenly dropped by performing operations such as signal detection, signal trend judgment, and terminal location scene judgment (high-speed rail / subway).

[0071] In some embodiments, the terminal can modify the event triggering condition of the second A2 event based on the fading rate of the signal strength of the target serving cell, the event triggering condition of the second A2 event, and the event triggering condition of the first A2 event. Accordingly, the terminal determines at least one of a second threshold offset value and a second time offset value based on the fading rate of the signal strength, the event triggering condition of the second A2 event, and the event triggering condition of the first A2 event. The second threshold offset value is negatively correlated with the difference between the triggering threshold value of the second A2 event and the triggering threshold value of the first A2 event, and positively correlated with the fading rate. The second time offset value is negatively correlated with the triggering time of the second A2 event and positively correlated with the fading rate. Then, the terminal decreases the triggering threshold value of the second A2 event by the second threshold offset value and / or extends the triggering time of the second A2 event by the second time offset value. Specifically, regarding the second threshold offset value, the larger the difference between the trigger threshold value of the second A2 event and the trigger threshold value of the first A2 event, the longer the event reporting interval between the first and second A2 events. Therefore, the terminal can reduce the reduction amount of the trigger threshold value of the second A2 event, i.e., reduce the second threshold offset value. Thus, the second threshold offset value is negatively correlated with the difference between the trigger threshold values ​​of the second and first A2 events. Conversely, the greater the signal strength fading rate, the shorter the event reporting interval between the first and second A2 events. Therefore, the terminal can increase the reduction amount of the trigger threshold value of the second A2 event, i.e., increase the second threshold offset value. Thus, the second threshold value is positively correlated with the fading rate. Regarding the second time offset value, the larger the trigger time of the second A2 event, the later the reporting time of the second A2 event. Therefore, the terminal can reduce the extension amount of the trigger time of the second A2 event, i.e., reduce the second time offset value. The greater the signal strength fading rate, the shorter the event reporting interval between the first A2 event and the second A2 event. Therefore, the terminal can increase the extension of the trigger time of the second A2 event, that is, increase the second time offset value. Thus, the second time offset value is negatively correlated with the trigger time of the second A2 event and positively correlated with the fading rate. By adaptively adjusting the reduction of the trigger threshold value and the extension of the trigger time of the second A2 event based on the difference between the trigger threshold values ​​of the first A2 event and the second A2 event, the signal strength fading rate of the target serving cell, and the trigger time of the second A2 event, the event reporting interval between the first A2 event and the second A2 event can be lengthened as much as possible. This increases the probability of the terminal successfully handing over to a neighboring cell in a weak network environment and reduces the probability of the terminal performing blind redirection.

[0072] For example, if the trigger threshold for the second A2 event is -96 dBm and the second threshold offset is 4 dBm, then the reduced trigger threshold for the second A2 event is -100 dBm. If the trigger time for the second A2 event is 160 ms and the second time offset is 40 ms, then the extended trigger time for the second A2 event is 200 ms.

[0073] 302. Based on the signal strength of the target serving cell, the fading rate of the signal strength, and the event triggering conditions of the modified second A2 event, determine the predicted reporting time of the second A2 event.

[0074] In this embodiment, when the signal strength of the target serving cell decreases to below the trigger threshold of the first A2 event, the terminal reports the first A2 event to the network device. Correspondingly, the network device sends measurement configuration information to the terminal for performing neighbor cell measurements. This measurement configuration information includes neighbor cell measurement events configured by the network device for the terminal and measurement configurations related to these events. The neighbor cell measurement events instruct the terminal to measure the neighbor cells of the target serving cell based on the measurement configurations in the measurement configuration information. After the event triggering conditions of the neighbor cell measurement event are met during the measurement process, the terminal can report the neighbor cell measurement event to the network device, that is, report the measurement results obtained from the neighbor cell measurement.

[0075] To determine whether the terminal can report neighbor cell measurement events before the reporting of the second A2 event during a sudden drop in the signal strength of the target serving cell, the terminal can predict the reporting time of the second A2 event, thus obtaining the predicted reporting time. Since this predicted reporting time is the time when the serving cell's signal strength is less than the modified trigger threshold of the second A2 event plus the modified trigger time of the second A2 event, the terminal can determine the time when the serving cell's signal strength is less than the modified trigger threshold of the second A2 event based on the target serving cell's signal strength, the signal fading rate, and the modified trigger threshold. Therefore, the terminal can determine the predicted reporting time of the second A2 event based on the time when the signal strength is less than the modified trigger threshold and the modified trigger time of the second A2 event.

[0076] 303. If the time interval between the predicted reporting time of the second A2 event and the reporting time of the first A2 event is less than the duration threshold, and the terminal has reported the first A2 event to the network device and has received the measurement configuration information sent by the network device, modify the measurement configuration information so that the reporting time of the neighboring cell measurement event indicated by the modified measurement configuration information is earlier than the reporting time of the second A2 event. The neighboring cell measurement event is used to indicate the measurement of the neighboring cells of the target serving cell based on the measurement configuration information.

[0077] In this embodiment, the duration threshold is used to indicate the expected duration for the terminal to complete the reporting of the neighboring cell measurement event after reporting the first A2 event. This expected duration can be determined based on the measurement configuration information or the historical duration for the terminal to complete the reporting of the neighboring cell measurement event after reporting the first A2 event; this embodiment does not impose any limitations on this. When the terminal reports the first A2 event, it can obtain the reporting time of the first A2 event. Correspondingly, if the time interval between the predicted reporting time of the second A2 event and the reporting time of the first A2 event is less than the duration threshold, it indicates that the predicted reporting interval between the second A2 event and the first A2 event is less than the expected duration for the terminal to complete the reporting of the neighboring cell measurement event. That is, the terminal cannot complete the reporting of the neighboring cell measurement event before the second A2 event is reported. Therefore, after receiving the measurement configuration information from the network device, the terminal can directly modify the measurement configuration information to accelerate the neighboring cell measurement process triggered after the first A2 event is reported, so that the reporting time of the neighboring cell measurement event indicated by the modified measurement configuration information is earlier than the reporting time of the second A2 event. By executing steps 302-303 above, the terminal can limit the conditions for modifying the measurement configuration information. That is, by determining whether the terminal can complete the reporting of the neighboring cell measurement event before the second A2 event is reported, it decides whether to modify the measurement configuration information. If the reporting of the neighboring cell measurement event can be completed before the second A2 event is reported, the measurement configuration information can be avoided, thereby saving the terminal's power consumption when performing neighboring cell measurements.

[0078] In some embodiments, the measurement configuration information includes neighboring cell measurement events, event triggering conditions for the neighboring cell measurement events, and the measurement period for the neighboring cell measurement events. Accordingly, during the modification of the measurement configuration information, the terminal can modify the event triggering conditions and the measurement period for the neighboring cell measurement events, respectively. Since the event triggering conditions for the neighboring cell measurement events include a first trigger threshold, a second trigger threshold, and a trigger time, the first trigger threshold indicates the signal strength of the target serving cell when the neighboring cell measurement event is triggered, the second trigger threshold indicates the signal strength of the neighboring cells of the target serving cell when the neighboring cell measurement event is triggered, the trigger time indicates the duration after the first and second trigger thresholds of the neighboring cell measurement event are met, and the measurement period indicates the frequency at which the terminal performs neighboring cell measurements, the terminal can increase the first trigger threshold and / or decrease the second trigger threshold, and / or shorten the trigger time and / or shorten the measurement period to advance the reporting time of the neighboring cell measurement events. By increasing the first trigger threshold and decreasing the second trigger threshold when the signal strength of the serving cell decreases, and shortening the trigger time, the speed at which the signal strength of the serving cell decreases to below the first trigger threshold for neighbor cell measurement events can be accelerated. This also accelerates the speed at which the terminal finds neighbor cells that meet the second trigger threshold and speeds up the reporting of neighbor cell measurement events. By shortening the measurement cycle of neighbor cell measurement events, the frequency of neighbor cell measurements performed by the terminal can be increased, enabling the terminal to complete the neighbor cell measurement process as quickly as possible. This ensures that the reporting time of neighbor cell measurement events is earlier than the reporting time of the second A2 event, increasing the probability of the terminal successfully switching to a neighbor cell in weak network environments and reducing the probability of the terminal performing blind redirection.

[0079] In some embodiments, the terminal can modify the measurement configuration information based on the signal strength of the target serving cell, the fading rate of the signal strength, and the event triggering conditions of the neighboring cell measurement event. Please refer to the following steps (1)-(2).

[0080] (1) Based on the signal strength of the target serving cell, the fading rate of the signal strength, and the event triggering conditions of the neighboring cell measurement events, the terminal determines at least one of the following: a third threshold offset, a fourth threshold offset, a third time offset, and a period offset. Specifically, for the third threshold offset, the greater the difference between the signal strength and the first triggering threshold of the neighboring cell measurement time, the slower the signal strength decreases to below the first triggering threshold. Therefore, the terminal can increase the increment of the first triggering threshold, which in turn increases the third threshold offset. Thus, the third threshold offset is positively correlated with the difference between the signal strength and the first triggering threshold. The greater the fading rate of the signal strength, the shorter the event reporting interval between the first A2 event and the second A2 event. To reduce the signal strength to below the first triggering threshold as quickly as possible, the terminal can increase the increment of the first triggering threshold, which in turn increases the third threshold offset. Therefore, the third threshold offset is positively correlated with the fading rate. For the fourth threshold offset value, the larger the second trigger threshold value, the slower the terminal finds neighboring cells that meet the second trigger threshold value. To find suitable neighboring cells as quickly as possible, the terminal can increase the reduction of the second trigger threshold value, which means increasing the fourth threshold offset value. The greater the signal strength fading rate, the shorter the event reporting interval between the first A2 event and the second A2 event. To find suitable neighboring cells as quickly as possible, the terminal can increase the reduction of the second trigger threshold value, which means increasing the fourth threshold offset value. Therefore, the fourth threshold offset value is positively correlated with the second trigger threshold value and the fading rate. For the third time offset value, the larger the trigger time of the neighboring cell measurement event, the later the reporting time of the neighboring cell measurement event. To report the neighboring cell measurement event as quickly as possible, the terminal can increase the reduction of the trigger time, which means increasing the third time offset value. The greater the signal strength fading rate, the shorter the event reporting interval between the first A2 event and the second A2 event. To report the neighboring cell measurement event as quickly as possible, the terminal can increase the reduction of the trigger time, which means increasing the third time offset value. Therefore, the third time offset value is positively correlated with the trigger time and fading rate of the neighboring cell measurement event. Regarding the period offset value, the larger the measurement period of the neighboring cell measurement event, the slower the terminal performs neighboring cell measurements. To complete the neighboring cell measurement as quickly as possible, the terminal can increase the shortening of the measurement period, i.e., increase the period offset value. The greater the signal strength fading rate, the shorter the event reporting interval between the first A2 event and the second A2 event. To complete the neighboring cell measurement as quickly as possible, the terminal can increase the shortening of the measurement period, i.e., increase the period offset value. Therefore, the period offset value is positively correlated with both the measurement period and the fading rate of the neighboring cell measurement event.

[0081] (2) The terminal increases the first trigger threshold by the third threshold offset, and / or decreases the second trigger threshold by the fourth threshold offset, and / or shortens the trigger time by the third time offset, and / or shortens the measurement period by the period offset. By adaptively adjusting the increase of the first trigger threshold, the decrease of the second trigger threshold, the shortening of the trigger time, and the shortening of the measurement period based on the difference between the signal strength and the first trigger threshold, the fading rate of the signal strength, the second trigger threshold of the neighbor cell measurement time, the trigger time, and the measurement period, the terminal can accelerate the execution and reporting of neighbor cell measurement events as much as possible, increase the probability of the terminal successfully switching to a neighbor cell in a weak network environment, and reduce the probability of the terminal performing blind redirection.

[0082] For example, if the first trigger threshold for a neighboring cell measurement event is -92 dBm and the third threshold offset is 2 dBm, then the increased first trigger threshold is -90 dBm. If the second trigger threshold for a neighboring cell measurement event is -98 dBm and the fourth threshold offset is 2 dBm, then the decreased second trigger threshold is -100 dBm. If the trigger time for a neighboring cell measurement event is 100 ms and the third time offset is 60 ms, then the shortened trigger time for a neighboring cell measurement event is 40 ms. If the measurement period for a neighboring cell measurement event is 100 ms and the period offset is 50 ms, then the shortened measurement period for a neighboring cell measurement event is 50 ms.

[0083] In some embodiments, if the triggering time of the second A2 event is not extended when the event triggering condition of the second A2 event is modified in step 301 above, during the process of the terminal measuring the neighboring cells of the target serving cell based on the modified measurement configuration information, the terminal can determine whether it can complete the reporting of the neighboring cell measurement event before the second A2 event is reported if the signal strength of the target serving cell is less than the triggering threshold value after the second A2 event is reduced. Based on the determination result, it can then determine whether the triggering time of the second A2 event needs to be extended. Since the predicted reporting time of the second A2 event is the time when the signal strength of the serving cell is less than the modified triggering threshold value of the second A2 event plus the triggering time of the second A2 event, the terminal can obtain the current time when the signal strength of the target serving cell is less than the triggering threshold value after the second A2 event is reduced, and then determine the predicted reporting time of the second A2 event based on the current time and the triggering time of the second A2 event. The terminal can determine the expected time for reporting neighboring cell measurement events after reporting the first A2 event based on the modified measurement configuration information. Furthermore, it can determine the predicted reporting time of the neighboring cell measurement events based on the reporting time and expected duration of the first A2 event. If the predicted reporting time of the second A2 event is earlier than the predicted reporting time of the neighboring cell measurement event, it indicates that the terminal cannot complete the reporting of the neighboring cell measurement event before the second A2 event is reported. Therefore, the terminal needs to extend the trigger time of the second A2 event to ensure successful reporting of the neighboring cell measurement event. By limiting the conditions for extending the trigger time of the second A2 event, the terminal can avoid extending the trigger time of the second A2 event if it can complete the reporting of the neighboring cell measurement event before the second A2 event is reported, thus avoiding affecting the reporting speed when the terminal subsequently triggers the second A2 event.

[0084] 304. Based on the measurement period in the modified measurement configuration information, multiple neighboring cells in the neighboring cell list are measured to obtain the measurement results of the neighboring cell measurement events. The measurement results are used to indicate the signal strength of multiple neighboring cells.

[0085] In this embodiment, the measurement configuration information includes not only neighbor cell measurement events, event triggering conditions for neighbor cell measurement events, and measurement periods, but may also include a list of neighbor cells of the target serving cell. Accordingly, based on the measurement periods in the modified measurement configuration information, the terminal can measure multiple neighbor cells in the neighbor cell list to obtain measurement results of neighbor cell measurement events. The measurement results are used to indicate the signal strength of multiple neighbor cells.

[0086] In some embodiments, neighboring cell measurement events include measurement events such as A3, A5, and B2. Events A3 and A5 are used for intra-system measurements, while event B2 is used for inter-system measurements.

[0087] In some embodiments, the signal strength of the serving cell or neighboring cell can be represented by one of RSRP (Reference Signal Receiving Power), RSSI (Received Signal Strength Indicator), and RSRQ (Reference Signal Receiving Quality). Alternatively, RSRP, RSSI, and RSRQ can be considered together to determine the signal strength of the serving cell or neighboring cell. This application embodiment does not impose any limitations on this.

[0088] 305. If the measurement result meets the event triggering conditions of the neighboring cell measurement event, the measurement result of the neighboring cell measurement event is reported to the network device, which then uses the measurement result to issue a handover command to the terminal.

[0089] In this embodiment, the measurement results include not only the terminal's measurements of multiple neighboring cells over a period of time, but also the terminal's measurements of the target serving cell. The event triggering conditions for a neighboring cell measurement event include a first trigger threshold, a second trigger threshold, and a trigger time. The first trigger threshold indicates the signal strength of the target serving cell when the neighboring cell measurement event is reported; the second trigger threshold indicates the signal strength of the neighboring cells of the target serving cell when the neighboring cell measurement event is reported; and the trigger time indicates the delayed reporting time of the neighboring cell measurement event. Therefore, if the signal strength of the target serving cell is lower than the first trigger threshold, the signal strength of the neighboring cells of the target serving cell is higher than the second trigger threshold, and this condition is met throughout the trigger time, it indicates that the measurement results meet the event triggering conditions for a neighboring cell measurement event. At this time, the terminal can report the measurement results of the neighboring cell measurement event to the network device, and the network device can select a suitable neighboring cell for the terminal based on the measurement results, and then issue a handover command to the terminal.

[0090] 306. In response to a handover command, switch from the target serving cell to the neighboring cell indicated by the handover command.

[0091] In this embodiment of the application, after receiving a handover instruction from a network device, the terminal can perform a cell handover so that the terminal can switch from the target serving cell where it is currently stationed to the neighboring cell indicated by the handover instruction.

[0092] To facilitate understanding of the measurement event processing method proposed in this application, embodiments of this application also provide... Figure 4 and Figure 5 .in, Figure 4 This is a schematic diagram illustrating a measurement event processing flow provided in an embodiment of this application. For example... Figure 4As shown, the measurement optimization conditions include whether the terminal is currently configured with multiple A2 events with different trigger threshold values, i.e., whether a first A2 event and a second A2 event are configured, and whether the signal strength of the serving cell where the terminal is currently camped has suddenly dropped. If both of these conditions are met, it indicates that the measurement optimization conditions are satisfied. When the terminal is configured with two A2 events, it can lengthen the event reporting interval between the first A2 event and the second A2 event by modifying the event trigger conditions of the first A2 event and / or the second A2 event. When the signal strength of the serving cell drops below the trigger threshold value of the first A2 event, the terminal can report the first A2 event to the network device, and thus receive the measurement configuration information issued by the network device. Before performing neighbor cell measurements, the terminal can also modify the measurement configuration information to speed up the execution and reporting of neighbor cell measurements. After the terminal performs neighbor cell measurements based on the modified measurement configuration information, it can report the measurement results to the network device. The network device can issue a handover command based on the measurement results. After receiving the handover command, the terminal can execute the handover command to switch from the serving cell to the neighbor cell indicated by the handover command.

[0093] join Figure 5 , Figure 5 This is a timing diagram illustrating the processing flow of a measurement event according to an embodiment of this application. The curves in the diagram represent changes in the signal strength of the serving cell where the terminal is camped, showing only the changes in signal strength when the signal strength drops sharply. Under measurement optimization conditions, the terminal can modify the event triggering conditions for the first A2 event and the second A2 event. Specifically, the terminal can shorten the triggering time of the first A2 event and / or increase the triggering threshold value of the first A2 event, and / or lengthen the triggering time of the second A2 event, and / or decrease the triggering threshold value of the second A2 event, thereby lengthening the event reporting interval between the first A2 event and the second A2 event. When the signal strength of the serving cell drops below the triggering threshold value of the first A2 event, that is, when the signal strength in the diagram meets the triggering threshold value of the first A2 event, the terminal can report the first A2 event to the network device after the triggering time of the first A2 event (0 in the diagram). Upon receiving measurement configuration information from the network device, the terminal can modify the measurement configuration information to accelerate the reporting of neighboring cell measurement events. By implementing the above modifications, the reporting time of the neighbor cell measurement event can be satisfied that it is earlier than the reporting time of the second A2 event, thereby enabling the terminal to receive the handover instruction issued by the network device before the second A2 event is reported and switch to the neighbor cell with better signal.

[0094] This application provides a method for handling measurement events. When a first A2 event and a second A2 event are triggered due to a sudden drop in the signal strength of the terminal's serving cell, the terminal can modify the event triggering conditions of the first A2 event and / or the second A2 event to increase the reporting interval between the first A2 event and the second A2 event, thereby reserving sufficient time for the terminal to perform subsequent neighbor cell measurements. Simultaneously, after the first A2 event is reported, the terminal can also modify the measurement configuration information issued by the network device to accelerate the reporting process of neighbor cell measurement events triggered after the first A2 event, ensuring that the reporting time of the neighbor cell measurement event is earlier than the reporting time of the second A2 event. This allows the terminal to receive the handover instruction issued by the network device before the second A2 event is reported, enabling it to switch to a neighbor cell with a better signal. This avoids blind redirection caused by the reporting of the second A2 event before the neighbor cell measurement event is completed, which could lead to service disruption and improve user experience.

[0095] All of the above-mentioned optional technical solutions can be combined in any way to form the optional embodiments of this application, and will not be described in detail here.

[0096] The following are embodiments of the apparatus described in this application, which can be used to execute the embodiments of the method described in this application.

[0098] The first modification module 601 is used to modify the event triggering conditions of the first A2 event and / or the second A2 event when the fading rate of the signal strength of the target serving cell is greater than the rate threshold, so as to increase the time interval between the reporting time of the first A2 event and the reporting time of the second A2 event, and the target serving cell is the serving cell where the terminal is currently camped.

[0099] The second modification module 602 is used to modify the measurement configuration information when the terminal has reported the first A2 event to the network device and received the measurement configuration information sent by the network device, so that the reporting time of the neighbor cell measurement event indicated by the modified measurement configuration information is earlier than the reporting time of the second A2 event. The neighbor cell measurement event is used to indicate the measurement of the neighbor cells of the target serving cell based on the measurement configuration information.

[0100] In some embodiments, the event triggering condition includes a triggering threshold and a triggering time. The triggering threshold is used to indicate the signal strength of the target serving cell when the first A2 event and the second A2 event are reported, and the triggering time is used to indicate the duration after the triggering threshold of the first A2 event or the second A2 event is met.

The second threshold offset value is negatively correlated with the difference between the triggering threshold value of the second A2 event and the triggering threshold value of the first A2 event, and positively correlated with the fading rate. The second time offset value is negatively correlated with the triggering time of the second A2 event and positively correlated with the fading rate. The second modification unit 702 is configured to decrease the triggering threshold value of the second A2 event by the second threshold offset value and / or extend the triggering time of the second A2 event by the second time offset value.

[0106] In some embodiments, see continue to see Figure 7 The second modification module 602 is used to determine the predicted reporting time of the second A2 event based on the signal strength of the target serving cell, the fading rate of the signal strength, and the event triggering conditions of the modified second A2 event; and to modify the measurement configuration information when the time interval between the predicted reporting time of the second A2 event and the reporting time of the first A2 event is less than the duration threshold, and the terminal has reported the first A2 event to the network device and received the measurement configuration information sent by the network device.

[0107] In some embodiments, the measurement configuration information includes a neighboring cell measurement event, an event triggering condition for the neighboring cell measurement event, and a measurement period for the neighboring cell measurement event. The event triggering condition includes a first triggering threshold, a second triggering threshold, and a triggering time. The first triggering threshold is used to indicate the signal strength of the target serving cell when the neighboring cell measurement event is triggered to be reported. The second triggering threshold is used to indicate the signal strength of the neighboring cells of the target serving cell when the neighboring cell measurement event is triggered to be reported. The triggering time is used to indicate the duration after the first triggering threshold and the second triggering threshold of the neighboring cell measurement event are met.

[0108] The second modification module 602 is used to increase the first trigger threshold value, and / or decrease the second trigger threshold value, and / or shorten the trigger time, and / or shorten the measurement cycle of the neighboring cell measurement event, so as to advance the reporting time of the neighboring cell measurement event.

[0109] In some embodiments, the second modification module 602 is configured to determine at least one of a third threshold offset value, a fourth threshold offset value, a third time offset value, and a period offset value based on the signal strength of the target serving cell, the fading rate of the signal strength, and the event triggering conditions of the neighboring cell measurement event. The third threshold offset value is positively correlated with the difference between the signal strength and the first trigger threshold value and the fading rate. The fourth threshold offset value is positively correlated with the second trigger threshold value and the fading rate. The third time offset value is positively correlated with the triggering time and the fading rate of the neighboring cell measurement event.

[0115] The measurement module 606 is used to measure multiple neighboring cells in the neighboring cell list based on the measurement period in the modified measurement configuration information, and to obtain the measurement results of the neighboring cell measurement events. The measurement results are used to indicate the signal strength of multiple neighboring cells.

[0116] The reporting module 607 is used to report the measurement results of the neighboring cell measurement event to the network device when the measurement results meet the event triggering conditions of the neighboring cell measurement event. The network device is used to send a handover command to the terminal based on the measurement results.

[0117] The handover module 608 is used to switch from the target serving cell to the neighboring cell indicated by the handover command in response to a handover command.

[0118] This application provides a measurement event processing apparatus. When a first A2 event and a second A2 event are triggered due to a sudden drop in the signal strength of the terminal's serving cell, the terminal can modify the event triggering conditions of the first A2 event and / or the second A2 event to increase the event reporting interval between the first A2 event and the second A2 event, thereby reserving sufficient time for the terminal to perform subsequent neighbor cell measurements. Simultaneously, after the first A2 event is reported, the terminal can also modify the measurement configuration information issued by the network device to accelerate the reporting process of neighbor cell measurement events triggered after the first A2 event, ensuring that the reporting time of the neighbor cell measurement event is earlier than the reporting time of the second A2 event. This allows the terminal to receive the handover instruction issued by the network device before the second A2 event is reported, enabling it to switch to a neighbor cell with a better signal. This avoids blind redirection caused by the reporting of the second A2 event before the neighbor cell measurement event is completed, which could lead to service disruption and improve user experience.
