[0042] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0043] Following the development of third-generation mobile communications technology and fourth-generation Long Term Evolution (LTE, 4G), the fifth-generation New Radio (NR, 5G) mobile communications technology has emerged, bringing faster network speeds, ultra-low latency, and greater data capacity, significantly improving user experience. At the same time, for example, voice services based on IMS (Voice over LTE, Volte) are gradually becoming part of users' lives.

[0044] We are currently in a period of rapid development of 5G network deployment. Since 4G networks have been widely deployed and have stable performance during their development and growth, making full use of the long-term evolution network architecture to deploy new wireless networks can greatly reduce network node deployment and reduce the complexity of the network system.

[0045] In current technology, the network measures, controls, and configures various events for the serving cell and neighboring cells that the terminal is currently accessing. For example, the A2 event indicates that the serving cell is worse than the absolute threshold, which can be used to enable measurements between certain cells. After the event occurs, operations such as handover may occur. The A4 event indicates that the neighboring cell is better than the absolute threshold. The above threshold values ​​are configured by the network. Due to differences in network deployment, the triggering threshold values ​​of the events may be configured unreasonably. When users use 5G network services, due to unreasonable network configuration threshold values, the terminal is triggered to frequently switch to access the network. During the network switching process, the terminal may lose network access.

[0046] For example, current operators' NSA (non-standalone) dual-link EN-DC (E-UTRA-NR Dual Connectivity) uses the 4G base station as the primary base station for signaling and the 5G base station as an extended and enhanced data transmission channel, thereby improving data transmission rates. In this case, the LTE base station eNB is the MN (Master Node), and the NR base station gNB is the SN (Secondary Node); the LTE cell is the MCG (Master Cell Group), and the NR cell is the SCG (Secondary Cell Group). The terminal registers in LTE-ENDC cell A, adds the 5G cell, and initiates a VoLTE call. When the terminal uses a VoLTE call, the voice service is transmitted as a data stream in the LTE data bearer network, eliminating the need to maintain or rely on the traditional circuit-switched voice network. The 5gSCG cell is in the hold state, and VoLTE data is sent and received over the LTE path.

[0047] The network measurement and control configuration measures the A2 event measured by the terminal's currently connected serving cell A and the A4 event measured by neighboring cell B. The network-configured A2 event threshold is -106dBm (Serving becomes worse than threshold). This means that if the network's measurement of the A2 event in cell A is less than the -106dBm threshold, the A2 event is reported. The network-configured A4 event threshold is -123dBm (Neighbour becomes better than threshold). When the cell signal falls below -110dBm, it significantly impacts the quality of calls made by the terminal. Therefore, the network-configured A4 event threshold for neighboring cell B is unreasonable and too low. During use, the terminal frequently triggers A4 event reporting due to the unreasonable and too low A4 event threshold. Upon receiving the A4 event, the network triggers a handover of the terminal's network connection from the current serving cell to the neighboring cell.

[0048] Because the threshold value of cell B is too low, when the network signal in cell B is poor, the terminal's network connection is switched from the current serving cell to neighboring cell B. After that, based on the measurement and control of cell B, it will be switched to cell C. For example, the A4 event measurement result of neighboring cell B is -116dBm, which is greater than the A4 event threshold value of -123dBm. Although the terminal's network connection is switched from the current cell A to neighboring cell B, due to the poor network signal in cell B, the network will trigger the terminal to switch to another adjacent cell C again.

[0049] Since the neighboring cell C is not an ENDC anchor LTE cell, the terminal switches to cell C and no 5G cell is added for a long time, resulting in the user being unable to connect to the 5G network and a poor user experience.

[0050] Based on this, the present disclosure provides a cell switching method, which triggers the reporting of the A4 measurement event of the neighboring cell when the measurement result of the terminal is greater than the network configuration measurement threshold value for triggering the A4 measurement event reporting, and at the same time meets the local configuration measurement threshold value for triggering the A4 measurement event reporting. The terminal connection network is switched based on the network switching instruction.

[0051] Figure 1 FIG. 1 is a flow chart showing a cell switching method according to an exemplary embodiment. Figure 1 As shown, the cell switching method is used in a terminal and includes the following steps.

[0052] In step S101, neighboring cells of the terminal are measured, and measurement results of the neighboring cells are determined.

[0053] In step S102, in response to the measurement result being greater than the first threshold value and greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported, wherein the first threshold value is the network configuration measurement threshold value for triggering the reporting of the A4 measurement event, the second threshold value is the local configuration measurement threshold value for triggering the reporting of the A4 measurement event, and the second threshold value is greater than the first threshold value.

[0054] In step S103, based on the network switching instruction, the network connection of the terminal is switched from the current serving cell to a neighboring cell.

[0055] In the embodiment of the present disclosure, during the use of the terminal, the network measures the neighboring cells of the terminal, controls and configures various events of the service cell and neighboring cells currently accessed by the terminal, and determines the measurement results of the neighboring cells. It can be understood that the service cell and neighboring cell currently accessed by the terminal can be 3G, 4G or 5G cells, and the embodiment of the present disclosure does not limit the service cell. For example, the A2 measurement event indicates that the service cell is worse than the absolute threshold, which can be used to enable measurements between certain cells. After the event occurs, operations such as switching may occur. The A4 measurement event indicates that the neighboring cell is better than the absolute threshold. The above threshold values ​​are configured by the network. Due to differences in network deployment, the triggering threshold values ​​of the events may be configured unreasonably. When a user uses a network service, due to unreasonable network configuration threshold values, the terminal is triggered to frequently perform switching operations to access the network. During the network switching process, the terminal may lose network access.

[0056] The network measures the neighboring cells of the terminal. When the measurement result of the A4 measurement event of the neighboring cell B is greater than the first threshold value and greater than the second threshold value, it triggers the reporting of the A4 measurement event of the neighboring cell. Among them, the first threshold value is the measurement threshold value for triggering the reporting of the A4 measurement event configured by the network, and the second threshold value is the measurement threshold value for triggering the reporting of the A4 measurement event configured locally by the terminal, and the second threshold value is greater than the first threshold value. When the cell signal is lower than a certain threshold, it will have a significant impact on the call effect of using the terminal. When the A4 event threshold value of the neighboring cell B configured by the network is too low, the A4 event of the neighboring cell B is reported based on the too low threshold value for triggering the reporting of the A4 event configured by the network, which will result in frequent triggering and reporting of the A4 event. After the network receives the A4 event, it triggers the unreasonable switching of the terminal's network connection from the current serving cell to the neighboring cell.

[0057] In the disclosed embodiment, when the network's measurement result of an A4 measurement event of a terminal's neighboring cell exceeds a first threshold and simultaneously satisfies a condition of being greater than a second threshold, the A4 measurement event of the neighboring cell is reported. Based on a network handover instruction, the terminal's network connection is switched from the current serving cell to the neighboring cell.

[0058] For example, the network measurement and control configures the A4 event measured in the neighboring cell B of the serving cell A to which the terminal is currently connected. The network-configured A4 event threshold for neighboring cell B, i.e., the first threshold, is -123dBm. The terminal locally configures the measurement threshold for triggering the reporting of the A4 measurement event, i.e., the second threshold, is -108dBm. The network measures the neighboring cell B of the terminal. When the measurement result is greater than the first threshold of -123dBm and greater than the second threshold of -108dBm, it triggers the reporting of the A4 measurement event for neighboring cell B. For example, when the network measures the neighboring cell B of the terminal and the measurement result is -116dBm, which is greater than the first threshold of -123dBm but less than the second threshold of -108dBm, the A4 measurement event is not reported. For another example, the network measures the neighboring cell B of the terminal. When the measurement result is -100dBm, which is greater than the first threshold value of -123dBm and the second threshold value of -108dBm, an A4 measurement event is reported.

[0059] According to an embodiment of the present disclosure, during the use of the terminal, when the measurement result of the neighboring cell of the terminal is greater than the network configuration measurement threshold value for triggering the reporting of the A4 measurement event, and at the same time, when the measurement result is greater than the local configuration measurement threshold value for triggering the reporting of the A4 measurement event, the A4 measurement event of the neighboring cell is triggered and reported, and the terminal connection network is switched based on the network switching instruction, thereby reducing frequent cell switching of the terminal, avoiding the terminal from registering to a cell with a poor signal environment, and improving the user experience.

[0060] Figure 2is a flow chart of a cell switching method according to an exemplary embodiment of the present disclosure. Figure 2 As shown, the cell switching method includes the following steps.

[0061] In step S201, neighboring cells of the terminal are measured, and measurement results of the neighboring cells are determined.

[0062] In step S202, in response to the measurement result being greater than the first threshold, a flag is set, where the flag is used to mark the presence of a neighboring cell whose measurement result is greater than the first threshold.

[0063] In step S203, in response to the measurement result being greater than the first threshold value and greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported, wherein the first threshold value is the network configuration measurement threshold value for triggering the reporting of the A4 measurement event, the second threshold value is the local configuration measurement threshold value for triggering the reporting of the A4 measurement event, and the second threshold value is greater than the first threshold value.

[0064] In step S204, based on the network switching instruction, the network connection of the terminal is switched from the current serving cell to a neighboring cell.

[0065] In an embodiment of the present disclosure, the network measures neighboring cells of a terminal, controls and configures various events for the serving cell and neighboring cells currently accessed by the terminal, and determines measurement results for the neighboring cells. The network measures neighboring cell B of the terminal. When the measurement result of the A4 measurement event of neighboring cell B is greater than a first threshold, a flag is set. The flag is used to indicate the presence of a neighboring cell with a measurement result greater than the first threshold, i.e., a network-configured measurement threshold value that triggers reporting of an A4 measurement event, but does not trigger reporting of the A4 measurement event for the neighboring cell.

[0066] When the measurement result of the A4 measurement event of the neighboring cell B is greater than the first threshold value and at the same time satisfies the condition greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported. The second threshold value is the measurement threshold value for triggering the reporting of the A4 measurement event configured locally by the terminal, and the second threshold value is greater than the first threshold value. When the cell signal is lower than a certain threshold, it will have a significant impact on the call effect when using the terminal. When the A4 event threshold value of the neighboring cell B configured by the network is too low, the A4 event of the neighboring cell B is reported based on the too low threshold value for triggering the reporting of the A4 event configured by the network, which will result in frequent triggering and reporting of the A4 event. After the network receives the A4 event, it triggers the unreasonable switching of the terminal's network connection from the current serving cell to the neighboring cell.

[0067] In the disclosed embodiment, when the network's measurement result of an A4 measurement event of a terminal's neighboring cell is greater than a first threshold and simultaneously satisfies a condition greater than a second threshold, the A4 measurement event of the neighboring cell is reported. Based on a network handover instruction, the terminal's network connection is switched from the current serving cell to the neighboring cell.

[0068] For example, the network measurement and control configuration configures the A4 event measured in neighboring cell B of the serving cell A currently accessed by the terminal. The network-configured A4 event threshold for neighboring cell B, i.e., the first threshold, is -123dBm. The terminal locally configures the measurement threshold for triggering the reporting of the A4 measurement event, i.e., the second threshold, is -108dBm. For example, the network measures neighboring cell B of the terminal. When the measurement result is -116dBm, which is greater than the first threshold of -123dBm, the network sets a flag bit to indicate that the A4 event measurement result for neighboring cell B is greater than the first threshold, but does not trigger the reporting of the neighboring cell's A4 measurement event. For example, the flag bit is set to neigh_become_better = 1.

[0069] For another example, the network measures the neighboring cell B of the terminal. When the measurement result is -100dbm, which is greater than the first threshold value of -123dbm, the flag is set to indicate that the A4 event measurement result of the neighboring cell B is greater than the first threshold value. At the same time, the measurement result is also greater than the second threshold value of -108dbm. At this time, the A4 measurement event is reported.

[0070] According to an embodiment of the present disclosure, during the use of a terminal, when the network's measurement result of an A4 measurement event of a terminal's neighboring cell is greater than a first threshold value, a flag is set to indicate that the measurement result is greater than the first threshold value, but does not trigger the reporting of the A4 measurement event of the neighboring cell. When the network's measurement result of the A4 measurement event of the terminal's neighboring cell is greater than the first threshold value and simultaneously satisfies the condition of being greater than a second threshold value, the reporting of the A4 measurement event of the neighboring cell is triggered. Based on a network switching instruction, the terminal's network connection is switched from the current serving cell to the neighboring cell, reducing frequent cell switching for the terminal, preventing the terminal from registering in a cell with a poor signal environment, and improving the user experience.

[0071] Figure 3 is a flow chart of a cell switching method according to an exemplary embodiment of the present disclosure. Figure 3 As shown, the cell switching method includes the following steps.

[0072] In step S301, neighboring cells of the terminal are measured, and measurement results of the neighboring cells are determined.

[0073] In step S302, in response to the measurement result being greater than the first threshold, a flag is set, where the flag is used to mark the presence of a neighboring cell whose measurement result is greater than the first threshold.

[0074] In step S303, in response to the measurement result being greater than the first threshold value and greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported, wherein the first threshold value is the network configuration measurement threshold value for triggering the reporting of the A4 measurement event, the second threshold value is the local configuration measurement threshold value for triggering the reporting of the A4 measurement event, and the second threshold value is greater than the first threshold value.

[0075] In step S304, based on the network switching instruction, the network connection of the terminal is switched from the current serving cell to the neighboring cell.

[0076] In step S305, the flag is cleared.

[0077] In an embodiment of the present disclosure, the network measures neighboring cells of a terminal, controls and configures various events for the serving cell and neighboring cells currently accessed by the terminal, and determines measurement results for the neighboring cells. The network measures neighboring cell B of the terminal. When the measurement result of the A4 measurement event of neighboring cell B is greater than a first threshold, a flag is set. The flag is used to indicate the presence of a neighboring cell with a measurement result greater than the first threshold, i.e., a network-configured measurement threshold value that triggers reporting of an A4 measurement event, but does not trigger reporting of the A4 measurement event for the neighboring cell.

[0078] When the measurement result of the A4 measurement event of the neighboring cell B is greater than the first threshold value and at the same time satisfies the condition greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported. The second threshold value is the measurement threshold value for triggering the reporting of the A4 measurement event configured locally by the terminal, and the second threshold value is greater than the first threshold value. When the cell signal is lower than a certain threshold, it will have a significant impact on the call effect when using the terminal. When the A4 event threshold value of the neighboring cell B configured by the network is too low, the A4 event of the neighboring cell B is reported based on the too low threshold value for triggering the reporting of the A4 event configured by the network, which will result in frequent triggering and reporting of the A4 event. After the network receives the A4 event, it triggers the unreasonable switching of the terminal's network connection from the current serving cell to the neighboring cell.

[0079] In the disclosed embodiment, when the network's measurement result of an A4 measurement event of a terminal's neighboring cell is greater than a first threshold and simultaneously satisfies a condition greater than a second threshold, the A4 measurement event of the neighboring cell is reported. Based on a network handover instruction, the terminal's network connection is switched from the current serving cell to the neighboring cell.

[0080] For example, the network measurement and control configuration configures the A4 event measured in neighboring cell B of serving cell A, to which the terminal is currently connected. The network-configured A4 event threshold for neighboring cell B, i.e., the first threshold, is -123dBm. The terminal locally configures the measurement threshold for triggering the reporting of the A4 measurement event, i.e., the second threshold, is -108dBm. For example, the network measures neighboring cell B of the terminal. When the measurement result is -116dBm, which is greater than the first threshold of -123dBm, the network sets a flag bit to indicate that the measurement result of the A4 event for neighboring cell B is greater than the first threshold, but does not trigger the reporting of the A4 measurement event for the neighboring cell. For example, the flag bit is set to neigh_become_better = 1. To prevent the set flag bit from being recovered in a timely manner, resulting in the marked bit being left behind and wasting resources, the flag bit needs to be cleared.

[0081] For another example, the network measures the neighboring cell B of the terminal. When the measurement result is -100dbm, which is greater than the first threshold value of -123dbm, the flag is set to indicate that the A4 event measurement result of the neighboring cell B is greater than the first threshold value. At the same time, the measurement result is also greater than the second threshold value of -108dbm. At this time, the A4 measurement event is reported.

[0082] According to an embodiment of the present disclosure, when the network measures the A4 measurement event of the terminal's neighboring cell to be greater than a first threshold value during the use of the terminal, a flag is set to indicate that the measurement result is greater than the first threshold value, but does not trigger the reporting of the A4 measurement event of the neighboring cell, and the flag is cleared in a subsequent process, thereby reducing the occupation of network resources. When the network measures the A4 measurement event of the terminal's neighboring cell to be greater than the first threshold value and simultaneously satisfies the condition of being greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported. Based on the network switching instruction, the network connection of the terminal is switched from the current serving cell to the neighboring cell, thereby reducing the frequent cell switching of the terminal, avoiding the terminal from registering to a cell with a poor signal environment, and improving the user experience.

[0083] Figure 4 is a flow chart of a cell switching method according to an exemplary embodiment of the present disclosure. Figure 4 As shown, the cell switching method includes the following steps.

[0084] In step S401, neighboring cells of the terminal are measured, and measurement results of the neighboring cells are determined.

[0085] In step S402, in response to the measurement result being greater than the first threshold, a flag is set, where the flag is used to mark the presence of a neighboring cell whose measurement result is greater than the first threshold.

[0086] In step S403, in response to the measurement result being greater than the first threshold value and greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported, wherein the first threshold value is the network configuration measurement threshold value for triggering the reporting of the A4 measurement event, the second threshold value is the local configuration measurement threshold value for triggering the reporting of the A4 measurement event, and the second threshold value is greater than the first threshold value.

[0087] In step S404, based on the network switching instruction, the network connection of the terminal is switched from the current serving cell to a neighboring cell.

[0088] In step S405, in response to triggering the reporting of the A4 measurement event of the neighboring cell, the flag is cleared.

[0089] In an embodiment of the present disclosure, the network measures neighboring cells of a terminal, controls and configures various events for the serving cell and neighboring cells currently accessed by the terminal, and determines measurement results for the neighboring cells. The network measures neighboring cell B of the terminal. When the measurement result of the A4 measurement event of neighboring cell B is greater than a first threshold, a flag is set. The flag is used to indicate the presence of a neighboring cell with a measurement result greater than the first threshold, i.e., a network-configured measurement threshold value that triggers reporting of an A4 measurement event, but does not trigger reporting of the A4 measurement event for the neighboring cell.

[0090] When the measurement result of the A4 measurement event of the neighboring cell B is greater than the first threshold value and at the same time satisfies the condition greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported. The second threshold value is the measurement threshold value for triggering the reporting of the A4 measurement event configured locally by the terminal, and the second threshold value is greater than the first threshold value. When the cell signal is lower than a certain threshold, it will have a significant impact on the call effect when using the terminal. When the A4 event threshold value of the neighboring cell B configured by the network is too low, the A4 event of the neighboring cell B is reported based on the too low threshold value for triggering the reporting of the A4 event configured by the network, which will result in frequent triggering and reporting of the A4 event. After the network receives the A4 event, it triggers the unreasonable switching of the terminal's network connection from the current serving cell to the neighboring cell.

[0091] In the disclosed embodiment, when the network's measurement result of an A4 measurement event of a terminal's neighboring cell is greater than a first threshold and simultaneously satisfies a condition greater than a second threshold, the A4 measurement event of the neighboring cell is reported. Based on a network handover instruction, the terminal's network connection is switched from the current serving cell to the neighboring cell.

[0092] For example, the network measurement and control configuration configures the A4 event measured in neighboring cell B of the serving cell A currently accessed by the terminal. The network-configured A4 event threshold for neighboring cell B, i.e., the first threshold, is -123dBm. The terminal locally configures the measurement threshold for triggering the reporting of the A4 measurement event, i.e., the second threshold, is -108dBm. For example, the network measures neighboring cell B of the terminal. When the measurement result is -116dBm, which is greater than the first threshold of -123dBm, the network sets a flag bit to indicate that the A4 event measurement result for neighboring cell B is greater than the first threshold, but does not trigger the reporting of the neighboring cell's A4 measurement event. For example, the flag bit is set to neigh_become_better = 1.

[0093] For example, if the network measures the terminal's neighboring cell B and the measurement result is -100dBm, which is greater than the first threshold of -123dBm, a flag is set to indicate that an A4 event has occurred in neighboring cell B. Simultaneously, the measurement result is also greater than the second threshold of -108dBm. At this point, an A4 measurement event is reported. After the A4 measurement event for the neighboring cell is reported, the flag is cleared to reduce network resource usage.

[0094] According to an embodiment of the present disclosure, during the use of the terminal, when the network's measurement result of the A4 measurement event of the terminal's neighboring cell is greater than the first threshold value, a flag is set to indicate that the measurement result is greater than the first threshold value, but the A4 measurement event of the neighboring cell is not triggered. When the network's measurement result of the A4 measurement event of the terminal's neighboring cell is greater than the first threshold value and simultaneously satisfies the condition of being greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported. After the A4 measurement event of the neighboring cell is triggered to be reported, the flag is cleared to reduce the occupation of network resources. Based on the network switching instruction, the terminal's network connection is switched from the current serving cell to the neighboring cell, reducing the frequent cell switching of the terminal, avoiding the terminal from registering to a cell with a poor signal environment, and improving the user experience.

[0095] Figure 5 is a flow chart of a cell switching method according to an exemplary embodiment of the present disclosure. Figure 5 As shown, the cell switching method includes the following steps.

[0096] In step S501, neighboring cells of the terminal are measured, and measurement results of the neighboring cells are determined.

[0097] In step S502, in response to the measurement result being greater than the first threshold, a flag is set, where the flag is used to mark the presence of a neighboring cell whose measurement result is greater than the first threshold.

[0098] In step S503, in response to the measurement result being greater than the first threshold value and greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported, wherein the first threshold value is the network configuration measurement threshold value for triggering the reporting of the A4 measurement event, the second threshold value is the local configuration measurement threshold value for triggering the reporting of the A4 measurement event, and the second threshold value is greater than the first threshold value.

[0099] In step S504, based on the network switching instruction, the network connection of the terminal is switched from the current serving cell to a neighboring cell.

[0100] In step S505, in response to determining that the current serving cell of the terminal meets the reporting conditions of the A2 measurement event and the reporting of the A2 measurement event is completed, and the flag bit exists and the reporting of the A4 measurement event is completed, the flag bit is cleared.

[0101] In an embodiment of the present disclosure, the network measures neighboring cells of a terminal, controls and configures various events for the serving cell and neighboring cells currently accessed by the terminal, and determines measurement results for the neighboring cells. The network measures neighboring cell B of the terminal. When the measurement result of the A4 measurement event of neighboring cell B is greater than a first threshold, a flag is set. The flag is used to indicate the presence of a neighboring cell with a measurement result greater than the first threshold, i.e., a network-configured measurement threshold value that triggers reporting of an A4 measurement event, but does not trigger reporting of the A4 measurement event for the neighboring cell.

[0102] When the measurement result of the A4 measurement event of the neighboring cell B is greater than the first threshold value and at the same time satisfies the condition greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported. The second threshold value is the measurement threshold value for triggering the reporting of the A4 measurement event configured locally by the terminal, and the second threshold value is greater than the first threshold value. When the cell signal is lower than a certain threshold, it will have a significant impact on the call effect when using the terminal. When the A4 event threshold value of the neighboring cell B configured by the network is too low, the A4 event of the neighboring cell B is reported based on the too low threshold value for triggering the reporting of the A4 event configured by the network, which will result in frequent triggering and reporting of the A4 event. After the network receives the A4 event, it triggers the unreasonable switching of the terminal's network connection from the current serving cell to the neighboring cell.

[0103] In the disclosed embodiment, when the network's measurement result of an A4 measurement event of a terminal's neighboring cell is greater than a first threshold and simultaneously satisfies a condition greater than a second threshold, the A4 measurement event of the neighboring cell is reported. Based on a network handover instruction, the terminal's network connection is switched from the current serving cell to the neighboring cell.

[0104] For example, the network measurement and control configuration configures the A4 event measured in neighboring cell B of the serving cell A currently accessed by the terminal. The network-configured A4 event threshold for neighboring cell B, i.e., the first threshold, is -123dBm. The terminal locally configures the measurement threshold for triggering the reporting of the A4 measurement event, i.e., the second threshold, is -108dBm. For example, the network measures neighboring cell B of the terminal. When the measurement result is -116dBm, which is greater than the first threshold of -123dBm, the network sets a flag bit to indicate that the A4 event measurement result for neighboring cell B is greater than the first threshold, but does not trigger the reporting of the neighboring cell's A4 measurement event. For example, the flag bit is set to neigh_become_better = 1.

[0105] For another example, the network measures the neighboring cell B of the terminal. When the measurement result is -100dbm, which is greater than the first threshold value of -123dbm, the flag is set to indicate that the A4 event measurement result of the neighboring cell B is greater than the first threshold value. At the same time, the measurement result is also greater than the second threshold value of -108dbm. At this time, the A4 measurement event is reported.

[0106] In the disclosed embodiments, an A2 measurement event indicates that the serving cell is worse than an absolute threshold and can be used to enable certain inter-cell measurements. After the event occurs, operations such as handover may occur. The network determines that the terminal's current serving cell meets the reporting conditions for the A2 measurement event and completes the reporting of the A2 measurement event. Furthermore, if a flag bit is present and the reporting of the A4 measurement event is completed, the flag bit is cleared.

[0107] For example, if the A2 event measurement result of serving cell A, currently connected to the network measurement terminal, is -110 dBm, which is less than the network-configured A2 event threshold of -106 dBm, the A2 event is reported. At this point, the A4 measurement event is reported, and a flag exists to indicate that the A4 measurement event result of neighboring cell B is greater than the first threshold. Clearing the flag prevents repeated marking of neighboring cell B with an A4 measurement event result greater than the first threshold, reducing network resource usage and the likelihood of erroneous A4 measurement event reporting.

[0108] According to an embodiment of the present disclosure, during the use of the terminal, when the network's measurement result of the A4 measurement event of the terminal's neighboring cell is greater than the first threshold value, a flag is set to mark that there is a measurement result greater than the first threshold value, but does not trigger the reporting of the A4 measurement event of the neighboring cell. When the network's measurement result of the A4 measurement event of the terminal's neighboring cell is greater than the first threshold value and simultaneously meets the condition of being greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered. The terminal's current serving cell meets the reporting conditions of the A2 measurement event, and the reporting of the A2 measurement event is completed. In addition, the flag bit is cleared, thereby reducing the occupation of network resources, reducing the frequent cell switching of the terminal, avoiding the terminal from registering to a cell with a poor signal environment, and improving the user experience.

[0109] Figure 6 is a flow chart of a cell switching method according to an exemplary embodiment of the present disclosure. Figure 6 As shown, the cell switching method includes the following steps.

[0110] In step S601, neighboring cells of the terminal are measured, and measurement results of the neighboring cells are determined.

[0111] In step S602, in response to the measurement result being greater than the first threshold, a flag is set, where the flag is used to mark the presence of a neighboring cell whose measurement result is greater than the first threshold.

[0112] In step S603, in response to the measurement result being greater than the first threshold value and greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported, wherein the first threshold value is the network configuration measurement threshold value for triggering the reporting of the A4 measurement event, the second threshold value is the local configuration measurement threshold value for triggering the reporting of the A4 measurement event, and the second threshold value is greater than the first threshold value.

[0113] In step S604, based on the network switching instruction, the network connection of the terminal is switched from the current serving cell to a neighboring cell.

[0114] In step S605, in response to the terminal receiving the network radio resource control RRC message release instruction, the flag bit is cleared.

[0115] In an embodiment of the present disclosure, the network measures neighboring cells of a terminal, controls and configures various events for the serving cell and neighboring cells currently accessed by the terminal, and determines measurement results for the neighboring cells. The network measures neighboring cell B of the terminal. When the measurement result of the A4 measurement event of neighboring cell B is greater than a first threshold, a flag is set. The flag is used to indicate the presence of a neighboring cell with a measurement result greater than the first threshold, i.e., a network-configured measurement threshold value that triggers reporting of an A4 measurement event, but does not trigger reporting of the A4 measurement event for the neighboring cell.

[0116] When the measurement result of the A4 measurement event of the neighboring cell B is greater than the first threshold value and at the same time satisfies the condition greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported. The second threshold value is the measurement threshold value for triggering the reporting of the A4 measurement event configured locally by the terminal, and the second threshold value is greater than the first threshold value. When the cell signal is lower than a certain threshold, it will have a significant impact on the call effect when using the terminal. When the A4 event threshold value of the neighboring cell B configured by the network is too low, the A4 event of the neighboring cell B is reported based on the too low threshold value for triggering the reporting of the A4 event configured by the network, which will result in frequent triggering and reporting of the A4 event. After the network receives the A4 event, it triggers the unreasonable switching of the terminal's network connection from the current serving cell to the neighboring cell.

[0117] In the disclosed embodiment, when the network's measurement result of an A4 measurement event of a terminal's neighboring cell is greater than a first threshold and simultaneously satisfies a condition greater than a second threshold, the A4 measurement event of the neighboring cell is reported. Based on a network handover instruction, the terminal's network connection is switched from the current serving cell to the neighboring cell.

[0118] For example, the network measurement and control configuration configures the A4 event measured in neighboring cell B of the serving cell A currently accessed by the terminal. The network-configured A4 event threshold for neighboring cell B, i.e., the first threshold, is -123dBm. The terminal locally configures the measurement threshold for triggering the reporting of the A4 measurement event, i.e., the second threshold, is -108dBm. For example, the network measures neighboring cell B of the terminal. When the measurement result is -116dBm, which is greater than the first threshold of -123dBm, the network sets a flag bit to indicate that the A4 event measurement result for neighboring cell B is greater than the first threshold, but does not trigger the reporting of the neighboring cell's A4 measurement event. For example, the flag bit is set to neigh_become_better = 1.

[0119] For another example, the network measures the neighboring cell B of the terminal. When the measurement result is -100dbm, which is greater than the first threshold value of -123dbm, the flag is set to indicate that the A4 event measurement result of the neighboring cell B is greater than the first threshold value. At the same time, the measurement result is also greater than the second threshold value of -108dbm. At this time, the A4 measurement event is reported.

[0120] In order to avoid the existence of the legacy flag bit occupying network resources, when the terminal receives the network radio resource control RRC message release instruction, it releases it and clears the flag bit to reduce the waste of network resources.

[0121] According to an embodiment of the present disclosure, during the use of the terminal, when the network's measurement result of the A4 measurement event of the terminal's neighboring cell is greater than a first threshold value, a flag is set to indicate that the measurement result is greater than the first threshold value, but the A4 measurement event of the neighboring cell is not triggered to be reported. When the network's measurement result of the A4 measurement event of the terminal's neighboring cell is greater than the first threshold value and simultaneously satisfies the condition of being greater than a second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported, and based on the network switching instruction, the terminal's network connection is switched from the current serving cell to the neighboring cell. In order to avoid the existence of the legacy flag bit occupying network resources, when the terminal receives the network radio resource control RRC message release instruction, the flag bit is cleared, thereby reducing the frequent cell switching of the terminal, avoiding the terminal from registering to a cell with a poor signal environment, and improving the user experience.

[0122] Figure 7 FIG. 1 is a flow chart showing a cell switching method according to an exemplary embodiment. Figure 7 As shown, the cell switching method includes the following steps.

[0123] In step S701, neighboring cells of the terminal are measured, and the measurement results of the neighboring cells are determined.

[0124] In step S702, the second threshold is dynamically adjusted based on the neighboring cell measurement result.

[0125] In step S703, in response to the measurement result being greater than the first threshold value and greater than the second threshold value, the A4 measurement event of the neighboring cell is triggered to be reported, wherein the first threshold value is the network configuration measurement threshold value for triggering the reporting of the A4 measurement event, the second threshold value is the local configuration measurement threshold value for triggering the reporting of the A4 measurement event, and the second threshold value is greater than the first threshold value.

[0126] In step S704, based on the network switching instruction, the network connection of the terminal is switched from the current serving cell to a neighboring cell.

[0127] In the disclosed embodiments, during the use of a terminal, the network controls and configures various events related to the serving cell and neighboring cells currently accessed by the terminal to determine the measurement results of the neighboring cells. The network configures the thresholds for measurement events. Due to differences in network deployment, the triggering thresholds for these events may be improperly configured.

[0128] The network measures the neighboring cells of the terminal. When the measurement result of the A4 measurement event of the neighboring cell B is greater than the first threshold value and greater than the second threshold value, it triggers the reporting of the A4 measurement event of the neighboring cell. Among them, the first threshold value is the measurement threshold value for triggering the reporting of the A4 measurement event configured by the network, and the second threshold value is the measurement threshold value for triggering the reporting of the A4 measurement event configured locally by the terminal, and the second threshold value is greater than the first threshold value. When the cell signal is lower than a certain threshold, it will have a significant impact on the call effect of using the terminal. When the A4 event threshold value of the neighboring cell B configured by the network is too low, the A4 event of the neighboring cell B is reported based on the too low threshold value for triggering the reporting of the A4 event configured by the network, which will result in frequent triggering and reporting of the A4 event. After the network receives the A4 event, it triggers the unreasonable switching of the terminal's network connection from the current serving cell to the neighboring cell.

[0129] In the disclosed embodiment, when the network's measurement result of an A4 measurement event of a terminal's neighboring cell exceeds a first threshold and simultaneously satisfies a condition of being greater than a second threshold, the A4 measurement event of the neighboring cell is reported. Based on a network handover instruction, the terminal's network connection is switched from the current serving cell to the neighboring cell.

[0130] For example, the network measurement and control configuration measures an A4 event in neighboring cell B, which is the serving cell A currently accessed by the terminal. The network-configured A4 event threshold for neighboring cell B is -123dBm, i.e., the first threshold. The terminal locally configures the measurement threshold for triggering the reporting of the A4 measurement event, i.e., the second threshold is -108dBm. The second threshold can be adjusted in real time and dynamically based on the terminal's measurement results of neighboring cell B. When the signal of neighboring cell B is good, the second threshold can be set to a relatively large value. When the signal of neighboring cell B is poor, the second threshold can be set to a relatively small value. The network measures the terminal's neighboring cell B. When the measurement result is greater than the first threshold of -123dBm and greater than the second threshold of -108dBm, the A4 measurement event for neighboring cell B is triggered and reported. For example, if the network measures the terminal's neighboring cell B and the measurement result is -116dBm, which is greater than the first threshold of -123dBm but less than the second threshold of -108dBm, then no A4 measurement event is reported. For another example, if the network measures the terminal's neighboring cell B and the measurement result is -100dBm, which is greater than the first threshold of -123dBm and also greater than the second threshold of -108dBm, then an A4 measurement event is reported.

[0131] According to an embodiment of the present disclosure, during the use of the terminal, when the measurement result of the neighboring cell of the terminal is greater than the network configuration measurement threshold value for triggering the reporting of the A4 measurement event, and at the same time, when the measurement result is greater than the local configuration measurement threshold value for triggering the reporting of the A4 measurement event, the A4 measurement event of the neighboring cell is triggered and reported, and the terminal connection network is switched based on the network switching instruction, thereby reducing frequent cell switching of the terminal, avoiding the terminal from registering to a cell with a poor signal environment, and improving the user experience.

Figure 11 As shown, the network measurement and control configuration terminal is in neighboring cell B. The measId is composed of the obj id of the measurement frequency and the report eventid. When measId is 5, it means that the signal of neighboring cell B is greater than the reporting condition of the network configuration A4 event.

Figure 12 As shown, the signal of the serving cell A currently accessed by the terminal is much higher than the signal of the neighboring cell C of the terminal.
