[0002] In an increasingly complex network environment, users are more likely to encounter communication anomalies in daily use. For example, in shopping districts with heavy traffic, airports, train stations or remote mountain villages, users may frequently encounter call establishment failures, unclear call sound quality, freezes and interruptions when browsing the web, watching live broadcasts or short videos, and high gaming latency. These anomalies seriously affect users' network experience.

[0003] Currently, the commonly used methods for escaping abnormal cells in response to network anomalies include disabling the cells or constructing a method of triggering handover by measurement reporting.

[0004] However, when the electronic device has a good signal, the network usually does not configure neighboring cells, resulting in the inability to obtain neighboring cell information, and thus the inability to directly disable the cell or build measurement and switch. In this case, current technical means cannot effectively deal with network anomalies. Summary of the invention

[0041] These technical standards provide different functions and services in different generations. With the evolution of technology, the performance and application scenarios of mobile communication networks are constantly expanding and optimizing.

[0042] A3 / A4 / A5 / A6, B1 / B2 are measurement events used to trigger neighbor measurements and handovers in mobile communication networks. These events define how the terminal performs neighbor measurements and handovers under different conditions to ensure network stability and user experience. The following is a detailed explanation of these measurement events:

[0043] A3 event: A3 event is used to trigger neighboring cell measurement. When the signal quality of the serving cell is lower than a certain threshold, the terminal starts to measure the neighboring cell signal. A3 event is usually used to trigger the terminal to perform neighboring cell measurement when the signal quality of the serving cell is poor, so as to switch to the neighboring cell with better signal quality in time.

[0044] A4 event: A4 event is used to trigger neighboring cell measurement. When the signal quality of the serving cell is higher than a certain threshold, the terminal starts to measure the neighboring cell signal. A4 event is usually used to trigger the terminal to perform neighboring cell measurement when the signal quality of the serving cell is good, so that it can switch to other cells in time when the signal quality decreases.

[0045] A5 event: A5 event is used to trigger neighboring cell measurement. When the signal quality of the serving cell is lower than a certain threshold and the signal quality of the neighboring cell is higher than another threshold, the terminal starts to measure the neighboring cell signal. A5 event is usually used to trigger the terminal to perform neighboring cell measurement when the signal quality of the serving cell is poor and the signal quality of the neighboring cell is good, so as to switch to the neighboring cell with better signal quality in time.

[0046] A6 event: A6 event is used to trigger neighboring cell measurement. When the signal quality of the serving cell is lower than a certain threshold and the signal quality of the neighboring cell is higher than another threshold, the terminal starts to measure the neighboring cell signal. A6 event is usually used to trigger the terminal to perform neighboring cell measurement when the signal quality of the serving cell is poor and the signal quality of the neighboring cell is good, so as to switch to the neighboring cell with better signal quality in time.

[0047] B1 event: B1 event is used to trigger neighboring cell measurement. When the signal quality of the serving cell is lower than a certain threshold, the terminal starts to measure the neighboring cell signal. B1 event is usually used to trigger the terminal to perform neighboring cell measurement when the signal quality of the serving cell is poor, so as to switch to the neighboring cell with better signal quality in time.

[0048] B2 event: B2 event is used to trigger neighboring cell measurement. When the signal quality of the serving cell is lower than a certain threshold and the signal quality of the neighboring cell is higher than another threshold, the terminal starts to measure the neighboring cell signal. B2 event is usually used to trigger the terminal to perform neighboring cell measurement when the signal quality of the serving cell is poor and the signal quality of the neighboring cell is good, so as to switch to the neighboring cell with better signal quality in time.

[0049] A3 / A4 / A5 / A6, B1 / B2 are measurement events used to trigger neighbor measurements and handovers in mobile communication networks. These events define how the terminal performs neighbor measurements and handovers under different conditions to ensure network stability and user experience. By properly configuring these measurement events, the handover efficiency and user experience of the network can be effectively improved.

[0050] Co-frequency neighboring cells refer to other cells adjacent to the current serving cell in the same frequency band. For example, in a 4G LTE network, co-frequency neighboring cells refer to adjacent cells using the same frequency band.

[0051] Inter-frequency neighbor cells refer to other cells adjacent to the current serving cell in different frequency bands. For example, in a 4G LTE network, inter-frequency neighbor cells may refer to adjacent cells using different frequency bands.

[0052] A heterogeneous system neighboring cell refers to another cell adjacent to the current serving cell and located in different communication systems. For example, in a 4G LTE network, a heterogeneous system neighboring cell may refer to an adjacent cell in a 3G WCDMA network or a 2G GSM network.

[0053] In a mobile communication network, when the number of network abnormal events in a cell of the same standard (such as 5G SA or LTE) exceeds a certain value for a period of time, it supports switching from SA mode to LTE mode, or from LTE mode to SA mode. This switching is called Radio Access Technology (RAT) replacement. The following are the key steps and methods to achieve this RAT replacement:

[0054] The network monitoring system detects abnormal conditions in the cell in real time, such as signal quality degradation, data transmission errors, user complaints, etc. The detected abnormalities are counted and the number and duration of abnormalities are recorded. When the number of network abnormal events exceeds the preset threshold and the duration exceeds the preset time period, the RAT change is triggered.

[0055] SA->LTE switching: When an abnormality occurs in the 5G SA cell, the network can trigger a switch from 5G SA mode to LTE mode. This switching can be achieved through the following steps:

[0056] The terminal measures the signal quality of the current 5G SA cell and reports it to the network. The network decides whether to change the RAT based on the measurement results and the preset switching strategy. If it decides to change the RAT, the network sends a switching command to the terminal, and the terminal switches from 5G SA mode to LTE mode.

[0057] LTE->SA switching: When an abnormality occurs in the LTE cell, the network can trigger a switch from LTE mode to 5G SA mode. This switch can be achieved through the following steps:

[0058] The terminal measures the signal quality of the current LTE cell and reports it to the network. The network decides whether to change the RAT based on the measurement results and the preset switching strategy. If it decides to change the RAT, the network sends a switching command to the terminal, and the terminal switches from LTE mode to 5G SA mode.

[0059] Switching parameter configuration, including: configuring switching thresholds and configuring switching strategies.

[0060] Configure handover thresholds, such as signal quality threshold, number threshold of network abnormal events, duration threshold, etc. When the terminal measurement results exceed these thresholds, handover is triggered.

[0061] Configure handover strategies, such as priority strategy, load balancing strategy, etc. Based on different strategies, decide which cell or RAT to handover to.

[0062] When the handover decision is made, the network sends a handover command to the terminal, and the terminal performs the RAT change. The handover process needs to ensure the continuity of data transmission and the smoothness of user experience. After the handover is completed, the network continues to monitor the signal quality and network performance of the new cell to ensure network stability and user experience after the handover.

[0063] When the number of network anomalies in the same standard cell exceeds a certain value for a period of time, it supports switching from SA mode to LTE mode, or from LTE mode to SA mode. This RAT change can be achieved through abnormal detection and statistics, RAT change strategy, switching parameter configuration, switching execution and optimization, and post-switching monitoring and adjustment. Through these steps, the stability of the network and user experience can be effectively improved.

[0064] In mobile communication networks, the Reference Signal Received Power (RSRP) is an important indicator for measuring signal strength. The RSRP offset of a serving cell or a neighboring cell refers to the value by which the RSRP of a serving cell or a neighboring cell is adjusted when a measurement event (such as A3, A4, A5, A6) is triggered. The following is a detailed explanation of the RSRP offset of a serving cell or a neighboring cell:

[0065] RSRP refers to the power of the reference signal of the serving cell or neighboring cell received by the terminal. RSRP is an important indicator for measuring signal strength, usually in dBm.

[0066] The offset is the value used to adjust the RSRP of the serving cell or neighboring cell when a measurement event is triggered. The offset can be a positive or negative value and is used to adjust the RSRP threshold.

[0067] RSRP offset of the serving cell: The RSRP offset of the serving cell refers to the value by which the RSRP of the serving cell is adjusted when a measurement event is triggered. For example, if the RSRP offset of the serving cell is +3dB, it means that the RSRP of the serving cell needs to be increased by 3dB when calculating the RSRP threshold.

[0068] Neighboring cell RSRP offset: The neighboring cell RSRP offset refers to the value by which the neighboring cell's RSRP is adjusted when a measurement event is triggered. For example, if the neighboring cell's RSRP offset is -2dB, it means that the neighboring cell's RSRP needs to be reduced by 2dB when calculating the RSRP threshold.

[0069] By adjusting the RSRP offset of the serving cell or neighboring cell, the RSRP threshold for triggering the measurement event can be adjusted, thereby affecting the triggering conditions for neighboring cell measurement and switching. By properly setting the RSRP offset, it is easier to trigger neighboring cell measurement and switching when the serving cell signal is weak, improving network stability and user experience.

[0070] In a mobile communication network, when a terminal detects a network outage, it will take a series of measures to restore the network connection based on different events and signal conditions configured in the network. These measures include intra-frequency handover, inter-frequency handover, and inter-system handover. The following is a detailed explanation of these three situations:

[0071] Intra-frequency handover: Intra-frequency handover means that a terminal switches from one cell to another within the same frequency band. For example, switching from one cell of a 4G LTE network to another 4G LTE cell.

[0072] When the terminal detects that the signal of the current serving cell is weak, but the signal of the neighboring cell with the same frequency is better, the same-frequency switching will be triggered.

[0073] The terminal detects that the signal of the current serving cell is weak, but the signal of the adjacent cell with the same frequency is better. By adjusting the offset of the A2 event, the adjacent cell configuration with the same frequency is triggered, and the adjacent cell with the same frequency is switched. The terminal switches to the adjacent cell with the same frequency with better signal and restores the network connection.

[0074] Inter-frequency handover refers to the terminal switching between different frequency bands. For example, switching from one cell of a 4G LTE network to another 4G LTE cell using a different frequency band.

[0075] When the signal of the same-frequency neighboring cell does not meet the set conditions, but the signal of the different-frequency neighboring cell is better, the different-frequency switching will be triggered.

[0076] The terminal detects that the signal of the same-frequency neighboring cell does not meet the set conditions, but the signal of the inter-frequency neighboring cell is better. By adjusting the offset of the A2 event, the inter-frequency neighboring cell configuration is triggered and the inter-frequency switching is performed. The terminal switches to the inter-frequency neighboring cell with better signal and restores the network connection.

[0077] Inter-system handover refers to the terminal switching between different communication systems, for example, switching from a 4G LTE network to a 3G WCDMA network.

[0078] When the signals of the same-frequency and different-frequency neighboring cells do not meet the set conditions, but the signals of the different-system neighboring cells are better, the different-system switching will be triggered.

[0079] The terminal detects that the signals of the same-frequency and different-frequency neighboring cells do not meet the set conditions, but the signal of the different-system neighboring cell is better. By adjusting the offset of the A2 event, the configuration of the different-system neighboring cell is triggered and the different-system switching is performed. The terminal switches to the different-system neighboring cell with better signal and restores the network connection.

[0080] In a mobile communication network, when a terminal detects a network outage, it will take measures such as intra-frequency switching, inter-frequency switching, and inter-system switching to restore network connection according to different events and signal conditions of the network configuration. Intra-frequency switching refers to switching within the same frequency band, inter-frequency switching refers to switching between different frequency bands, and inter-system switching refers to switching between different communication systems. Through these switching measures, the stability of the network and user experience can be effectively improved.

[0081] In response to the problems arising from the related technologies, the embodiments of the present application provide a cell switching method, device, electronic device and readable storage medium, which can solve the problem that the related technologies cannot effectively deal with network anomalies.

[0082] The cell switching method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0083] Figure 1 A flowchart of a cell switching method provided in an embodiment of the present application.

[0084] like Figure 1 As shown, the cell switching method may include steps 110 to 140, and the method is applied to a cell switching device, as shown below:

[0085] Step 110, the electronic device detects a network abnormality event of a serving cell to which the electronic device is currently connected within a preset detection time period;

[0086] Preset detection duration: A pre-set period of time used to detect network anomalies in the service cell to which the electronic device is currently connected, and used to determine the time window for detection.

[0087] Network abnormality event: refers to network performance problems that occur when electronic devices are connected to a service cell, such as decreased signal strength, deteriorated signal quality, data transmission failure, etc., which are used to determine whether the network status of the current service cell is normal.

[0088] During the preset detection time, the electronic device continuously monitors the network status of the currently connected service cell. If a network abnormality event is detected, such as a drop in signal strength or a deterioration in signal quality, the event is recorded, and by detecting the network abnormality event, it is determined whether the network status of the current service cell is stable.

[0089] Step 120, the electronic device counts the number of occurrences of network abnormal events within a preset detection time period according to the detection result;

[0090] According to the detection result of step 110, the number of occurrences of network abnormal events within the preset detection time is counted. The more the number of occurrences of network abnormal events is, the more unstable the network state of the current serving cell is. By counting the number of occurrences of network abnormal events, the degree of network abnormality of the current serving cell can be quantified.

[0091] Step 130, the electronic device adjusts the threshold parameter threshold of the cell switching measurement event step by step according to the number of occurrences of the network abnormal event and the signal judgment result, and obtains the adjusted threshold parameter threshold, wherein the signal judgment result is used to indicate whether the neighboring cell signal of the serving cell meets the preset signal condition;

[0092] Signal judgment result: used to indicate whether the neighboring cell signal of the serving cell meets the preset signal conditions, such as signal strength, signal quality, etc., and is used to evaluate whether the neighboring cell signal is suitable as a switching target.

[0093] Cell switching measurement event: refers to the measurement event used to trigger cell switching, such as A2 event, B1 event, B2 event, etc., which is used to determine whether it is necessary to switch from the current serving cell to other cells.

[0094] According to the number of occurrences of network abnormal events and the signal judgment results, the threshold parameter threshold of the cell switching measurement event is adjusted step by step. The following is an explanation with specific examples:

[0095] The electronic device is communicating in service cell A. The network needs to dynamically adjust the threshold parameter of the A2 event according to the signal conditions of cell B, which is the same-frequency neighboring cell of service cell A, and cell C, which is the different-frequency neighboring cell of service cell A.

[0096] The initial threshold parameter is -90dBm, that is, when the signal strength of serving cell A is lower than -90dBm, the A2 event is triggered. The preset signal conditions include: the signal strength of the same-frequency neighboring cell must be higher than -95dBm. The signal strength of the different-frequency neighboring cell must be higher than -100dBm. The preset number of network abnormal events is 5 times.

[0097] During a certain period of time, the following abnormal events were monitored: Number of switching failures: 2 times. Number of signal quality degradation after switching: 1 time. Number of user complaints: 1 time. Therefore, the number of network abnormal events: 4 times. The number of network abnormal events is greater than 1 and less than the preset number threshold of 5 times.

[0098] Then, the electronic device determines whether the same-frequency neighboring cell signal meets the preset signal condition. The signal strength of the serving cell A is -88dBm. The signal strength of the same-frequency neighboring cell B is -96dBm. The signal strength of the same-frequency neighboring cell B is -96dBm, which does not meet the preset signal condition.

[0099] Since the number of occurrences of the network abnormality event is greater than 1 and less than the preset number threshold, and the same-frequency neighboring cell signal does not meet the preset signal condition, the electronic device reduces the threshold parameter threshold of the A2 event to the first parameter threshold. The first parameter threshold is -88dBm.

[0100] Then, the electronic device monitors the signal measurement event of the same-frequency neighboring cell. The signal measurement results include: the signal strength of the serving cell A is -87dBm. The signal strength of the same-frequency neighboring cell B is -95dBm. The signal strength of the same-frequency neighboring cell B is -95dBm, which still does not meet the preset signal condition.

[0101] Since the co-frequency neighboring cell signal still does not meet the preset signal condition, and the number of occurrences of the network abnormality event is still greater than 1 and less than the preset number threshold, the electronic device reduces the threshold parameter threshold of the A2 event from the first parameter threshold to the second parameter threshold. The second parameter threshold is -86dBm.

[0102] Then, the electronic device starts to monitor the signal measurement event of the inter-frequency neighboring cell C. Determine whether the inter-frequency neighboring cell signal meets the preset signal condition. The signal strength of the serving cell A is -86dBm. The signal strength of the inter-frequency neighboring cell C is -101dBm. The signal strength of the inter-frequency neighboring cell C is -101dBm, which does not meet the preset signal condition.

[0103] Because the number of occurrences of network abnormal events reaches the preset number threshold, and the hetero-frequency neighboring cell signal does not meet the preset signal condition, the electronic device reduces the threshold parameter threshold of the A2 event from the second parameter threshold to the third parameter threshold. The third parameter threshold is -84dBm.

[0104] The electronic device requests to configure the measurement events of the heterogeneous system, such as B1 events or B2 events, to further optimize the switching strategy. The electronic device dynamically adjusts the threshold parameter threshold of the A2 event according to the number of occurrences of network abnormal events and the signal judgment results, as follows: The same-frequency neighboring area signal does not meet the preset signal conditions, and the threshold parameter is reduced from -90dBm to -88dBm. The same-frequency neighboring area signal still does not meet the preset signal conditions, the threshold parameter is reduced from -88dBm to -86dBm, and the heterogeneous frequency neighboring area signal is monitored. The heterogeneous frequency neighboring area signal does not meet the preset signal conditions, the threshold parameter is reduced from -86dBm to -84dBm, and the configuration of the heterogeneous system measurement event is requested.

[0105] In this way, the switching strategy can be effectively optimized, switching failures and user complaints can be reduced, and network performance and user experience can be improved.

[0106] If the number of network abnormal events is high and the neighboring cell signal does not meet the preset conditions, the threshold parameter threshold is lowered to make the measurement event easier to trigger. By adjusting the threshold parameter threshold, the cell switching measurement event is triggered in advance to ensure that the electronic device can switch to a more stable cell in time.

[0107] Step 140: The electronic device switches the currently connected serving cell according to the adjusted threshold parameter value.

[0108] Threshold parameter threshold: The signal strength or signal quality threshold used to trigger the measurement event. Used to control the triggering conditions of the measurement event, such as triggering the A2 event when the signal is lower than a certain threshold.

[0109] According to the threshold parameter threshold adjusted in step 130, a cell switching measurement event is triggered. If the signal of the current serving cell is lower than the threshold parameter threshold adjusted, a switching operation is triggered to switch to a neighboring cell or other cell. The adjusted threshold parameter threshold ensures that the device can switch to a more stable cell in time to avoid communication interruption.

[0110] By detecting network anomalies and adjusting threshold parameter thresholds, electronic devices can discover network problems in the current service cell earlier and switch to a more stable cell in a timely manner, effectively avoiding communication interruptions or performance degradation caused by network anomalies.

[0111] By adjusting the threshold parameter thresholds step by step, the electronic device can dynamically adjust the switching strategy according to the degree of network anomaly. For example, when the network anomaly is mild, the electronic device can maintain a high threshold parameter threshold to avoid frequent switching; when the network anomaly is severe, the electronic device can lower the threshold parameter threshold to trigger switching in advance.

[0112] By adjusting the threshold parameter, the electronic device can trigger the switching operation in advance to avoid the switching delay caused by signal deterioration, and ensure that the electronic device switches to a more stable cell in time before the signal deteriorates to the point of being unavailable. By switching to a more stable cell in time, the electronic device can provide users with higher quality communication services, reduce problems such as signal interruption and data transmission failure, and improve the user's communication experience.

[0113] In a possible embodiment, step 120 may specifically include the following steps: the electronic device starts a timer to obtain a timing duration;

[0114] When the timing duration of the electronic device does not exceed the preset detection duration and the detection result is that a network abnormal event occurs, the initial number of occurrences of the network abnormal event is increased by 1 to obtain the number of occurrences of the network abnormal event;

[0115] When the timing duration of the timer exceeds the preset detection duration and the number of occurrences of the network abnormal event does not reach the preset number, the electronic device resets the timing duration to 0.

[0116] The electronic device starts a timer to record the current timing duration. The timing duration of the timer starts from 0 and gradually increases as time goes by. The timer records the time to ensure that network abnormal events are counted within the preset detection duration.

[0117] If the timer duration does not exceed the preset detection duration, the detection of network abnormal events continues. The preset detection duration is, for example, 10 seconds or 30 seconds. If the detection result is that a network abnormal event occurs, the initial number of occurrences of the network abnormal event is increased by 1. The number of occurrences of network abnormal events can be counted within the preset detection duration.

[0118] If the timer duration exceeds the preset detection duration and the number of occurrences of network anomalies does not reach the preset number, the timer duration is reset to 0. The preset number of times is, for example, 3 or 5. After resetting the timer duration, the timer restarts and continues to detect network anomalies. Within the preset detection duration, if the number of occurrences of network anomalies does not reach the preset number, the timer restarts to avoid triggering the switching operation too early.

[0119] Through the management of timers and timing duration, the number of occurrences of network anomalies can be accurately counted within the preset detection duration, which can avoid statistical errors caused by inconsistent time windows. If the number of occurrences of network anomalies does not reach the preset number, the device will reset the timing duration to 0 and start the timing again, which can avoid misjudgment caused by insufficient occurrences of network anomalies.

[0120] By counting the number of occurrences of network anomalies, electronic devices can dynamically adjust the switching trigger conditions according to the degree of network anomalies. For example, when the network anomaly is mild, the electronic device can maintain a high threshold parameter value to avoid frequent switching; when the network anomaly is severe, the electronic device can lower the threshold parameter value to trigger the switching in advance.

[0121] By managing timers and timing durations, electronic devices can more accurately control the time point of switching triggering, ensuring that when network anomalies reach a certain level, the device triggers the switching operation in a timely manner to avoid communication interruption.

[0122] In a possible embodiment, the cell switching measurement event is an A2 event, and step 130 may specifically include the following steps:

[0123] Step 210: When the number of occurrences of the network abnormal event is greater than 1 and less than a preset number threshold, the electronic device determines whether the same-frequency neighboring cell signal of the serving cell meets a preset signal condition;

[0124] Step 220: When the same-frequency neighboring cell signal does not meet the preset signal condition, the electronic device reduces the threshold parameter threshold of the A2 event to the first parameter threshold to obtain the adjusted threshold parameter threshold.

[0125] A2 event: A measurement event in wireless communication, used to determine whether the signal of the current serving cell is below a certain threshold. Usually used to trigger cell reselection or handover.

[0126] Network abnormality event: refers to network performance problems that occur when electronic devices are connected to a service cell, such as decreased signal strength, deteriorated signal quality, data transmission failure, etc., which are used to determine whether the network status of the current service cell is normal.

[0127] Preset signal conditions: conditions used to determine whether the neighboring cell signal meets the switching requirements, such as signal strength, signal quality, etc., used to evaluate whether the neighboring cell signal is suitable as a switching target.

[0128] Co-frequency neighboring cell signal: The signal of the neighboring cell operating in the same frequency band as the current serving cell is used to determine whether the current network status can be improved through co-frequency switching.

[0129] When the number of occurrences of network abnormal events is greater than 1 and less than the preset number threshold, the electronic device determines whether the co-frequency neighboring cell signal of the serving cell meets the preset signal condition. If the co-frequency neighboring cell signal meets the preset signal condition, it means that the co-frequency neighboring cell can be used as a switching target. If the co-frequency neighboring cell signal does not meet the preset signal condition, it means that the co-frequency neighboring cell cannot improve the current network status. By determining whether the co-frequency neighboring cell signal meets the preset signal condition, it is evaluated whether the current network status can be improved through co-frequency switching.

[0130] Threshold parameter threshold: The threshold of signal strength or signal quality used to trigger the measurement event. It is used to control the triggering conditions of the measurement event. For example, when the signal is lower than a certain threshold, the A2 event is triggered.

[0131] First parameter threshold: An adjustment value of the threshold parameter threshold of the A2 event, which is usually lower than the initial threshold parameter threshold, making the A2 event easier to trigger, so that the switching operation can be taken earlier.

[0132] If the co-frequency neighboring cell signal does not meet the preset signal condition, the electronic device lowers the threshold parameter threshold of the A2 event to the first parameter threshold. After lowering the threshold parameter threshold, the A2 event is more likely to be triggered, so that the switching operation is taken earlier. By lowering the threshold parameter threshold of the A2 event, the A2 event is triggered in advance, ensuring that the device can switch to other cells in time when the signal of the current serving cell is poor.

[0133] By lowering the threshold parameter of the A2 event, the electronic device can trigger the A2 event earlier, thereby taking a switching operation earlier, thereby avoiding communication interruption caused by signal deterioration.

[0134] When the number of occurrences of network abnormal events is greater than 1 and less than the preset number threshold, the electronic device will determine whether the same-frequency neighboring cell signal meets the preset signal condition. If the same-frequency neighboring cell signal does not meet the preset signal condition, the electronic device will lower the threshold parameter threshold of the A2 event and trigger the A2 event in advance. The switching strategy can be dynamically adjusted according to the degree of network abnormality to ensure the accuracy of the switching operation.

[0135] By switching to a more stable cell in a timely manner, electronic devices can provide users with higher quality communication services, reduce problems such as signal interruptions and data transmission failures, and improve users' communication experience.

[0136] By lowering the threshold parameter of the A2 event, the electronic device can trigger the switching operation in advance to avoid switching delays caused by signal deterioration, and ensure that the electronic device can switch to a more stable cell in time before the signal deteriorates to the point of being unusable.

[0137] On the one hand, when the number of occurrences of network abnormal events is greater than 1 and less than the preset number threshold, the electronic device detects that the signal of the same-frequency neighboring cell meets the preset signal condition. The electronic device can choose to switch to the same-frequency neighboring cell without lowering the threshold parameter threshold of the A2 event, ensuring that the electronic device can switch to a more stable cell when the signal of the current service cell is poor, thereby improving the communication quality.

[0138] On the other hand, when the number of occurrences of network abnormal events is greater than 1 and less than the preset number threshold, the electronic device detects that the same-frequency neighboring cell signal does not meet the preset signal condition, and the electronic device lowers the threshold parameter threshold of the A2 event to the first parameter threshold, triggering the A2 event in advance to ensure that the electronic device can switch to other cells in time when the current service cell signal is poor to avoid communication interruption.

[0139] In a possible embodiment, after step 220, the method further includes:

[0140] Step 230, the electronic device monitors the signal measurement event of the same frequency neighboring cell of the serving cell;

[0141] Step 240: When the signal of the same-frequency neighboring cell still does not meet the preset signal condition, and when the number of occurrences of network abnormal events of the electronic device is still greater than 1 and less than the preset number threshold, the threshold parameter threshold of the A2 event is reduced from the first parameter threshold to the second parameter threshold, and the signal measurement events of the different-frequency neighboring cells of the service cell are monitored, and the second parameter threshold is less than the first parameter threshold.

[0142] Co-frequency neighboring cell signal: The signal of the neighboring cell operating in the same frequency band as the current serving cell is used to determine whether the current network status can be improved through co-frequency switching.

[0143] Inter-frequency neighboring cell signal: The signal of the neighboring cell operating in a different frequency band from the current serving cell, used to determine whether the current network status can be improved through inter-frequency switching.

[0144] Signal measurement event: an event used to monitor and evaluate the signal strength or quality of neighboring cells, such as A2 event, B1 event, B2 event, etc., to determine whether it is necessary to switch from the current serving cell to another cell.

[0145] First parameter threshold: An adjustment value of the threshold parameter threshold of the A2 event, which is usually lower than the initial threshold parameter threshold, making the A2 event easier to trigger, so that the switching operation can be taken earlier.

[0146] Second parameter threshold: another adjustment value of the threshold parameter threshold of the A2 event, which is lower than the first parameter threshold, further reducing the triggering conditions of the A2 event, making the A2 event easier to trigger.

[0147] Preset signal conditions: conditions used to determine whether the neighboring cell signal meets the switching requirements, such as signal strength, signal quality, etc., used to evaluate whether the neighboring cell signal is suitable as a switching target.

[0148] After lowering the threshold parameter threshold of the A2 event to the first parameter threshold, the electronic device continues to monitor the signal measurement events of the same-frequency neighboring cells of the serving cell. By monitoring the signal measurement events, the electronic device can evaluate the signal status of the same-frequency neighboring cells in real time. By monitoring the signal measurement events of the same-frequency neighboring cells, it is determined whether the current network status can be improved by switching to the same frequency.

[0149] If the co-frequency neighboring cell signal still does not meet the preset signal condition, and the number of occurrences of the network abnormal event is still greater than 1 and less than the preset number threshold, the electronic device reduces the threshold parameter threshold of the A2 event from the first parameter threshold to the second parameter threshold. The second parameter threshold is less than the first parameter threshold, further reducing the triggering condition of the A2 event. The electronic device triggers the A2 event in advance by further reducing the threshold parameter threshold of the A2 event, ensuring that the electronic device can switch to other cells in time when the signal of the current serving cell is poor.

[0150] After lowering the threshold parameter threshold of the A2 event to the second parameter threshold, the electronic device begins to monitor the signal measurement events of the inter-frequency neighboring cells of the service cell. By monitoring the signal measurement events of the inter-frequency neighboring cells, the electronic device can evaluate the signal status of the inter-frequency neighboring cells and determine whether the current network status can be improved by inter-frequency switching. By monitoring the signal measurement events of the inter-frequency neighboring cells, it is determined whether the current network status can be improved by inter-frequency switching.

[0151] By further reducing the threshold parameter of the A2 event, the electronic device can trigger the A2 event earlier, thereby taking a switching operation earlier, thereby avoiding communication interruption caused by signal deterioration.

[0152] When the signal of the same-frequency neighboring cell does not meet the preset signal conditions, the electronic device will continue to lower the threshold parameter of the A2 event and monitor the signal measurement events of the different-frequency neighboring cell. The switching strategy can be dynamically adjusted according to the degree of network abnormality to ensure the accuracy of the switching operation.

[0153] By switching to a more stable cell in time, electronic devices can provide users with higher quality communication services, reduce problems such as signal interruption and data transmission failure, and improve users' communication experience. By further lowering the threshold parameter of the A2 event, electronic devices can trigger switching operations in advance to avoid switching delays caused by signal deterioration, ensuring that electronic devices can switch to a more stable cell in time before the signal deteriorates to the point of being unavailable.

[0154] On the one hand, when the signal of the same-frequency neighboring cell does not meet the preset signal condition, the electronic device reduces the threshold parameter threshold of the A2 event to the second parameter threshold and monitors the signal measurement event of the different-frequency neighboring cell. This ensures that the electronic device can switch to the different-frequency neighboring cell or other cells in time to avoid communication interruption when the signal of the current serving cell is poor.

[0155] On the other hand, when the signal of the same-frequency neighboring cell meets the preset signal conditions, the electronic device can choose to switch to the same-frequency neighboring cell without further lowering the threshold parameter threshold of the A2 event. This ensures that the electronic device can switch to a more stable cell when the signal of the current serving cell is poor, thereby improving the communication quality.

[0156] In a possible embodiment, after step 240, the method further includes:

[0157] Step 250: When the number of occurrences of network abnormal events reaches a preset number threshold, the electronic device determines whether the inter-frequency neighboring cell signal of the serving cell meets a preset signal condition;

[0158] Step 260: When the hetero-frequency neighboring cell signal does not meet the preset signal condition and the B1 event or the B2 event is not configured, the electronic device reduces the threshold parameter threshold of the A2 event from the second parameter threshold to the third parameter threshold, and requests to configure a measurement event of the hetero-system, where the third parameter threshold is less than the second parameter threshold.

[0159] Inter-frequency neighboring cell signal: The signal of the neighboring cell operating in a different frequency band from the current serving cell, used to determine whether the current network status can be improved through inter-frequency switching.

[0160] Preset signal conditions: conditions used to determine whether the neighboring cell signal meets the switching requirements, such as signal strength, signal quality, etc., used to evaluate whether the neighboring cell signal is suitable as a switching target.

[0161] B1 event and B2 event: measurement events in wireless communication, used to trigger the measurement of inter-frequency neighboring cells and the measurement of inter-systems respectively, and used to determine whether it is necessary to switch from the current serving cell to an inter-frequency or inter-system.

[0162] Second parameter threshold: an adjustment value of the threshold parameter threshold of the A2 event, which is lower than the initial threshold parameter threshold, making the A2 event easier to trigger, so that the switching operation is taken earlier.

[0163] The third parameter threshold is another adjustment value of the threshold parameter threshold of the A2 event, which is usually lower than the second parameter threshold, further reducing the triggering conditions of the A2 event, making the A2 event easier to trigger.

[0164] Alien system measurement events: events used to monitor and evaluate the signal strength or quality of alien systems, and to determine whether it is necessary to switch from the current system to the alien system.

[0165] When the number of occurrences of network abnormal events reaches the preset number threshold, the electronic device determines whether the heterofrequency neighboring cell signal of the serving cell meets the preset signal condition. If the heterofrequency neighboring cell signal meets the preset signal condition, it means that the heterofrequency neighboring cell can be used as a switching target. If the heterofrequency neighboring cell signal does not meet the preset signal condition, it means that the heterofrequency neighboring cell cannot improve the current network status. By judging whether the heterofrequency neighboring cell signal meets the preset signal condition, it is evaluated whether the current network status can be improved through heterofrequency switching.

[0166] If the inter-frequency neighboring cell signal does not meet the preset signal condition and the B1 event or B2 event is not configured, the electronic device reduces the threshold parameter threshold of the A2 event from the second parameter threshold to the third parameter threshold. The third parameter threshold is less than the second parameter threshold, further reducing the triggering condition of the A2 event. By further reducing the threshold parameter threshold of the A2 event, the A2 event is triggered in advance, ensuring that the electronic device can switch to other cells in time when the signal of the current serving cell is poor.

[0167] After lowering the threshold parameter of the A2 event to the third parameter threshold, the electronic device requests to configure a measurement event of a different system. By configuring a measurement event of a different system, the electronic device can evaluate the signal status of the different system and determine whether the current network status can be improved by switching to a different system. By requesting to configure a measurement event of a different system, it is ensured that the electronic device can switch to a different system as soon as possible when the signal of the current system is poor.

[0168] By further reducing the threshold parameter of the A2 event, the electronic device can trigger the A2 event earlier, thereby taking a switching operation earlier, thereby avoiding communication interruption caused by signal deterioration.

[0169] When the heterodyne signal does not meet the preset signal conditions, the electronic device will continue to lower the threshold parameter of the A2 event and request to configure a heterodyne measurement event. The switching strategy can be dynamically adjusted according to the degree of network anomaly to ensure the accuracy of the switching operation.

[0170] By switching to a more stable cell or system in a timely manner, electronic devices can provide users with higher quality communication services, reduce problems such as signal interruptions and data transmission failures, and improve users' communication experience.

[0171] By further lowering the threshold parameter of the A2 event, the electronic device can trigger the switching operation in advance to avoid switching delays caused by signal deterioration, and ensure that the electronic device can switch to a more stable cell or system in time before the signal deteriorates to the point of being unusable.

[0172] On the one hand, when the hetero-frequency neighboring cell signal does not meet the preset signal condition, the electronic device reduces the threshold parameter threshold of the A2 event to the third parameter threshold and requests to configure the hetero-system measurement event. This ensures that the electronic device can switch to the hetero-system or other cells in time to avoid communication interruption when the current serving cell signal is poor.

[0173] On the other hand, when the inter-frequency neighboring cell signal meets the preset signal conditions, the electronic device can choose to switch to the inter-frequency neighboring cell without further lowering the threshold parameter threshold of the A2 event. This ensures that the electronic device can switch to a more stable cell when the current serving cell signal is poor, thereby improving communication quality.

[0174] In a possible embodiment, after step 260, the following steps may also be included:

[0175] Receiving heterogeneous system measurement configuration information sent by a network side device, wherein the heterogeneous system measurement configuration information includes frequency point information, measurement event type, and measurement threshold parameters of a target heterogeneous system;

[0176] Measuring the signal of the target heterogeneous system according to the heterogeneous system measurement configuration information to obtain signal quality information of the target heterogeneous system;

[0177] When the signal quality information meets the triggering condition of the measurement event of the heterogeneous system, reporting the measurement result of the heterogeneous system to the network side device;

[0178] According to the switching instruction sent by the network side device based on the measurement result, a switching operation of the different system is performed.

[0179] The frequency information of the target alien system refers to the specific information of the wireless frequency band used by the target alien system, such as 5G NR, GSM, Wi-Fi, etc. The frequency information usually includes the center frequency, bandwidth, and band identifier. The frequency information is used to indicate the frequency range that the electronic device needs to pay attention to when measuring the target alien system signal. For example, the target alien system is 5G NR, and the frequency information is n78. The target alien system is GSM, and the frequency information is 900MHz.

[0180] The measurement event type refers to the specific event type used to trigger measurement or switching. In heterosystem measurements, common measurement event types include B1 events and B2 events. The B1 event is used to indicate that the signal quality of heterofrequency or heterosystem neighboring cells is better than a certain threshold. The B2 event is used to indicate that the signal quality of the serving cell is lower than a certain threshold, and the signal quality of heterofrequency or heterosystem neighboring cells is better than another threshold. The measurement event type is used to define when to start measuring the signal of the target heterosystem and when to trigger switching. For example, the B1 event is used to detect whether the signal of the heterosystem neighboring cells is good enough to trigger switching.

[0181] For example, the measurement event type is B1 event, which is used to detect whether the signal of the 5G NR neighboring cell is better than -100dBm. The measurement event type is B2 event, which is used to detect whether the LTE serving cell signal is lower than -90dBm and whether the 5G NR neighboring cell signal is better than -105dBm.

[0182] The measurement threshold parameter is the threshold of the signal strength or quality used to trigger the measurement event. For example, the measurement threshold parameter of the B1 event may be -100dBm, which means that the B1 event is triggered when the signal strength of the target heterogeneous system neighboring cell is higher than -100dBm. The measurement threshold parameter is used to define when the measurement event is triggered. For example, when the signal strength or quality of the target heterogeneous system neighboring cell reaches or exceeds the measurement threshold parameter, the corresponding measurement event is triggered.

[0183] The electronic device receives the heterogeneous system measurement configuration information sent by the network side device, including the frequency information, measurement event type and measurement threshold parameters of the target heterogeneous system. According to the heterogeneous system measurement configuration information, the electronic device measures the signal of the target heterogeneous system to obtain signal quality information. By receiving the heterogeneous system measurement configuration information, the electronic device can accurately measure the signal quality of the target heterogeneous system, providing a basis for subsequent switching decisions.

[0184] When the signal quality of the target heterogeneous system meets the triggering conditions of the measurement event, the electronic device reports the measurement results to the network side device. The network side device determines whether to trigger the handover based on the measurement results. By reporting the measurement results, the network side device can make a handover decision in time to ensure that the user equipment can switch to a cell with better signal.

[0185] According to the switching instruction sent by the network side device, the electronic device performs the switching operation of the heterogeneous system, switching the user equipment from the current cell to the target heterogeneous system cell. By performing the heterogeneous system switching operation, it can ensure that the user equipment can seamlessly switch to a heterogeneous system cell with better signal when the signal of the current cell deteriorates, thereby improving the user experience.

[0186] By dynamically adjusting the threshold parameter threshold of the A2 event, the switching measurement can be triggered earlier before the service cell signal deteriorates, reducing the probability of switching failure. By requesting the configuration of a measurement event of a different system, the range of the switching target can be expanded to ensure that when the current frequency band or signal is poor, it is possible to switch to a different system cell with a better signal. By receiving different system measurement configuration information and reporting measurement results, the network-side device can make a switching decision in a timely manner to ensure that the user device can switch to a cell with a better signal. By performing a switching operation of a different system, it can be ensured that the user device can seamlessly switch to a different system cell with a better signal when the signal of the current cell deteriorates, reducing communication interruptions and improving user experience.

[0187] In a possible embodiment, the electronic device determines whether the network switching is successful when sending a switching command to the network side device;

[0188] When the network switching is successful, the electronic device stops accessing the network corresponding to the network abnormality event within a preset time period;

[0189] When the network switching fails, the electronic device re-executes the steps of the method as claimed in claim 1.

[0190] Handover command: A command sent by an electronic device to a network device to request a handover from the current serving cell to a target cell or system, and to trigger the network device to perform a handover operation.

[0191] Network switching: The process of switching an electronic device from the current serving cell to the target cell or system, which is used to improve the current network status and ensure the continuity and stability of communication.

[0192] Network switching success: The electronic device successfully switches from the current serving cell to the target cell or system. When the network switching is successful, the electronic device is ensured to access a more stable cell or system to improve the communication quality.

[0193] Network handover failure: The electronic device fails to successfully switch from the current serving cell to the target cell or system, which may cause communication interruption or performance degradation.

[0194] Preset time period: A pre-set period of time used to control electronic devices to stop accessing the network corresponding to the network abnormality event after the switch is successful. This prevents electronic devices from re-accessing an unstable cell or system immediately after the switch is successful.

[0195] After sending a switching command to the network side device, the electronic device will determine whether the network switching is successful. If the switching is successful, the electronic device will proceed to the next step; if the switching fails, the electronic device will re-execute the previous method steps. By judging the switching result, it is ensured that the electronic device can take corresponding actions in time.

[0196] If the network switch is successful, the electronic device will stop accessing the network corresponding to the network abnormality event within a preset time period. This can prevent the device from re-accessing an unstable cell or system immediately after the switch is successful. By stopping access to the network corresponding to the network abnormality event, it is ensured that the electronic device can stably access the target cell or system.

[0197] If the network switching fails, the electronic device will re-execute the previous method steps, such as detecting network abnormal events, adjusting threshold parameter thresholds, etc., to ensure that the electronic device can take action again after the switching failure to avoid communication interruption.

[0198] By re-executing the steps of the method, it is ensured that the electronic device can take action again after the switching failure, thereby avoiding communication interruption.

[0199] By determining whether the network switching is successful, the electronic device can take corresponding actions in a timely manner to improve the success rate of the switching and avoid communication interruption caused by switching failure.

[0200] When the network switching is successful, the electronic device will stop accessing the network corresponding to the network abnormality event within a preset time period, which can prevent the electronic device from re-accessing an unstable cell or system immediately after the switching is successful, thereby improving the communication quality.

[0201] By switching to a more stable cell or system in a timely manner, electronic devices can provide users with higher quality communication services, reduce problems such as signal interruptions and data transmission failures, and improve users' communication experience.

[0202] In the event of a network switching failure, the electronic device will re-execute the previous method steps to ensure that the electronic device can take action again after the switching failure, thereby avoiding communication interruption caused by the switching failure.

[0203] On the one hand, the electronic device successfully switches from the current service cell to the target cell or system, and the electronic device stops accessing the network corresponding to the network abnormality event within a preset time period, ensuring that the electronic device can stably access the target cell or system and improve communication quality.

[0204] On the other hand, if the electronic device fails to successfully switch from the current serving cell to the target cell or system, the electronic device re-executes the previous method steps, such as detecting network abnormal events, adjusting threshold parameter thresholds, etc., to ensure that the electronic device can take action again after the switching failure to avoid communication interruption.

[0205] In an embodiment of the present application, the electronic device detects a network abnormality event of a service cell to which the electronic device is currently connected within a preset detection time. The electronic device counts the number of occurrences of the network abnormality event within the preset detection time according to the detection result, and quantifies the degree of network abnormality of the current service cell by counting the number of occurrences of the network abnormality event. The electronic device adjusts the threshold parameter threshold of the cell switching measurement event step by step according to the number of occurrences of the network abnormality event and the signal judgment result to obtain the adjusted threshold parameter threshold, wherein the signal judgment result is used to indicate whether the neighboring cell signal of the service cell meets the preset signal condition. By adjusting the threshold parameter threshold step by step, the electronic device can dynamically adjust the switching strategy according to the degree of network abnormality. If the number of occurrences of the network abnormality event is large and the neighboring cell signal does not meet the preset condition, the cell switching measurement event is triggered in advance by adjusting the threshold parameter threshold to ensure that the electronic device can switch to a more stable cell in time. The electronic device switches the currently connected service cell according to the adjusted threshold parameter threshold. By switching to a more stable service cell in time, the electronic device can provide users with higher quality communication services and improve the user's communication experience.

[0221] In a possible embodiment, the statistics module 320 is specifically configured to:

[0222] Start the timer to obtain the timing duration;

[0223] If the timing duration does not exceed the preset detection duration and the detection result is that a network abnormality event occurs, the initial number of occurrences of the network abnormality event is increased by 1 to obtain the number of occurrences of the network abnormality event;

[0224] When the timer duration exceeds the preset detection duration and the number of occurrences of network abnormal events does not reach the preset number, the timer duration is reset to 0.

[0228] The execution module is used for the electronic device to re-execute the steps of the method as claimed in claim 1 when the network switching fails.

[0229] In an embodiment of the present application, the electronic device detects a network abnormality event of a service cell to which the electronic device is currently connected within a preset detection time. The electronic device counts the number of occurrences of the network abnormality event within the preset detection time according to the detection result, and quantifies the degree of network abnormality of the current service cell by counting the number of occurrences of the network abnormality event. The electronic device adjusts the threshold parameter threshold of the cell switching measurement event step by step according to the number of occurrences of the network abnormality event and the signal judgment result to obtain the adjusted threshold parameter threshold, wherein the signal judgment result is used to indicate whether the neighboring cell signal of the service cell meets the preset signal condition. By adjusting the threshold parameter threshold step by step, the electronic device can dynamically adjust the switching strategy according to the degree of network abnormality. If the number of occurrences of the network abnormality event is large and the neighboring cell signal does not meet the preset condition, the cell switching measurement event is triggered in advance by adjusting the threshold parameter threshold to ensure that the electronic device can switch to a more stable cell in time.
