AI Technical Summary
When the terminal moves to the edge of the cell, the signal of the serving cell changes too quickly, resulting in failure to complete the measurement of adjacent cells before blind redirection, resulting in service interruption and stuttering.
When the cell signal strength reaches the trigger blind redirect threshold, if the cell indication information of different network standards is received, the terminal does not immediately perform blind redirection, but performs cell handover after measuring and determining availability to avoid service interruption.
By delaying blind redirection, we ensure that the terminal does not interrupt services before finding available cells, avoids lag, and maintains communication continuity.

[0003] However, since the serving cell signal may change too quickly during the movement of the terminal, the terminal may trigger blind redirection before finding other available cells through measurement, which may cause terminal service disconnection, freeze and other abnormal situations.

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.
[0023] The terms "first", "second", etc. in the specification of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0024] The terms "at least one (item)", "at least one of" and the like in the specification of the present application refer to any one, any two or a combination of more than two of the objects contained therein. For example, at least one (item) of a, b, and c can be represented by: "a", "b", "c", "a and b", "a and c", "b and c" and "a, b and c", where a, b, and c can be single or multiple. Similarly, "at least two (items)" refers to two or more, and its meaning is similar to that of "at least one (item)". The logo in the present application is text, symbol, image, etc. used to indicate information, and logos or other containers can be used as carriers for displaying information, including but not limited to text logos, image logos, symbol logos, etc.
[0025] Some terms and nouns involved in the embodiments of the present application are explained below.
[0026] 1. A1 incident
[0027] The A1 event can be used to trigger the cancellation of an ongoing handover process. When the signal strength of the serving cell measured by the terminal exceeds the threshold corresponding to the A1 event, the terminal can be triggered to report the A1 event to the network side device to cancel the ongoing handover process. For example, the terminal can trigger a handover process when it moves to the edge of the cell, but then moves back to the previous coverage area with good signals. At this time, the terminal can cancel the ongoing handover process by reporting the A1 event.
[0028] 2. A2 incident
[0029] A2 events are usually used to trigger measurements of neighboring cells. For example, after the terminal reports an A2 event to the network side device, the network side device can configure measurement gaps and inter-frequency or inter-system measurements for the terminal. A2 events can indicate that the network coverage conditions are relatively poor at this time, and it is very likely that a handover will be required, so measurements between the same frequency, different frequencies, or systems need to be completed.
[0030] 3. A3 incident
[0031] The A3 event is usually used in the intra-frequency or inter-frequency switching process. When the neighboring cell exceeds the hysteresis higher than the primary service cell (SpCell), the terminal can be triggered to report the A3 event to the network side device. When the A2 event is triggered, the network side device can configure the measurement interval, the measurement inter-frequency object and the A3 event for inter-frequency switching. In other words, the A3 event provides a switching trigger mechanism based on relevant measurement results. For example, the network side device can be configured to trigger the A3 event when the neighboring cell reference signal receiving power (RSRP) is stronger than the RSRP of a specific cell.
[0032] 4. B1 incident
[0033] The B1 event is a heterogeneous system measurement event used in the inter-system handover process, which does not depend on the coverage of the serving cell. It determines whether it is necessary to switch to the target cell of another network based on the signal level threshold. If the signal level of the heterogeneous system neighboring cell is detected to be better than a certain threshold and can provide sufficient coverage, the B1 event may be triggered, causing the terminal to switch from the current system to the heterogeneous system cell.
[0034] 5. B2 Incident
[0035] When the signal strength of the primary service cell is lower than the threshold a corresponding to the B2 event, and the signal strength of the adjacent heterogeneous cell is higher than the threshold b corresponding to the B2 event, the B2 event can be triggered. At this time, the primary service cell deteriorates, which can trigger the switching process of the heterogeneous cell to ensure that the adjacent heterogeneous cell has sufficient coverage.
[0036] It should be noted that the heterogeneous cell in the embodiment of the present application may refer to a cell of a different network standard from the current serving cell. For example, in the process of transitioning from a 4G LTE network to a 5G NR network, the terminal needs to switch from a cell of one system to a cell of another system to ensure communication continuity and service quality.
[0037] It should be noted that the above events can also be expressed as measurement events. The two have the same meaning and can be interchangeable.
[0038] The cell switching method, device, terminal, medium and computer program product provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.
[0039] The cell switching method, device, terminal, medium and computer program product provided in the embodiments of the present application can be applied to scenarios where a terminal switches between cells of different network standards, especially when the terminal moves to the edge of a cell of a certain network standard and performs cell switching.
[0040] Take the case where the terminal resides in a 5G cell. If the terminal moves to the edge of the 5G cell, the signal of the 5G cell becomes worse. Then the network side device can instruct the terminal to switch to a 4G cell or other 5G frequency cell to continue to provide a good communication experience for the terminal.
[0041] Among them, the network side device can configure multiple A2 events for the terminal. For example, the first A2 event triggers 5G inter-frequency cell measurement when the serving cell RSRP is lower than 105dBm, the second A2 event triggers the measurement of the inter-system 4G cell when the serving cell RSRP is lower than -110dBm, and the third A2 event triggers blind redirection to the 5G inter-frequency cell when the serving cell RSRP is lower than -118dBm.
[0042] It is understandable that for each event, the network side device will configure the corresponding RSRP threshold and trigger time (timeToTrigger). That is, the terminal needs to continuously meet the RSRP threshold time to reach the corresponding timeToTrigger duration before the terminal reports the corresponding event.
[0043] Taking the process in which the 5G signal changes from good to bad when the terminal resides in a 5G cell as an example, the cell switching process executed by the terminal and the network side device may include the following steps S1 to S8.
[0044] Step S1: After the terminal resides in the 5G service cell, the network side device can configure A1 event and A2 event for the terminal.
[0045] The terminal may report the A1 event when the signal strength of the serving cell is higher than the threshold corresponding to the A1 event, and may report the A2 event when the signal strength of the serving cell is lower than the threshold corresponding to the A2 event.
[0046] Step S2: When the terminal moves toward the edge of the 5G service cell, if the terminal detects that the 5G service cell signal is lower than the reporting threshold of the first A2 event, the terminal may report the first A2 event.
[0047] Step S3: After receiving the A2 event reported by the terminal, the network side device may configure an A3 event for the terminal.
[0048] The above-mentioned A3 event can be used for measuring and reporting of inter-frequency adjacent cells.
[0049] Step S4: As the terminal continues to move toward the edge of the 5G cell, the 5G signal continues to deteriorate. If the terminal detects that the signal strength of the serving cell is lower than the reporting threshold of the second A2 event, the terminal may report the second A2 event.
[0050] Step S5: After receiving the second A2 event reported by the terminal, the network side device may configure a B1 event or a B2 event for the terminal.
[0051] Among them, the above-mentioned B1 event and B2 event can be used for measurement and reporting of cells of different systems.
[0052] Step S6: When reporting a B1 event or a B2 event, the terminal may switch the serving cell to a 4G cell of a different system.
[0053] Step S7: When the terminal detects that the signal strength of the serving cell is lower than the reporting threshold of the third A2 event, the terminal may report the third A2 event.
[0054] Step S8: After receiving the third A2 event reported by the terminal, the network side device may release the Radio Resource Control (RRC) link and instruct the terminal to blindly redirect to other cells with different frequencies.
[0055] It is understandable that in this case, the terminal can perform blind redirection. In other words, the terminal can start the blind redirection process and reside in other hetero-frequency cells after searching the network.
[0056] However, since the 5G signal may change too quickly during the movement of the terminal, the terminal may report the second A2 event, and after the network device configures the B1 event or B2 event, the terminal has not had time to report the B1 event or B2 event, but has already reported the third A2 event. At this time, the network device will release the RRC link and instruct the terminal to perform blind redirection to other cells with different frequencies, resulting in the disconnection of the terminal's services and abnormal conditions such as freezes in live broadcasts or games.
[0057] In the embodiment of the present application, the terminal may not report the third A2 event during the movement, but may first detect whether it is necessary to report the B1 event or the B2 event, and if it is necessary to report the B1 event or the B2 event, give priority to reporting the B1 event or the B2 event.
[0058] It should be noted that the above description is only based on the scheme of measuring other cells when the terminal resides in a 5G cell. In actual implementation, the cell switching method provided in the embodiment of the present application can also be applied to network standards other than 5G, such as 6G, 4G, etc. The embodiment of the present application is not specifically limited.
[0059] The cell switching method provided in the embodiment of the present application, when the signal strength of the service cell of the terminal reaches the threshold value for triggering blind redirection, if the terminal receives indication information for measuring a cell of a different network standard, the terminal may not perform blind redirection first. Instead, when the measurement determines that the cell of the different network standard is available, the terminal's service cell is first switched to the cell of the different network standard, so as to avoid the terminal performing blind redirection when the terminal measures and searches for an available cell, thereby maintaining terminal service continuity and avoiding freezes.
[0060] The execution subject of the cell switching method provided in the embodiment of the present application may be a cell switching device. Exemplarily, the cell switching device may be a terminal, or a component in the terminal, such as an integrated circuit or a chip. The cell switching method provided in the embodiment of the present application will be exemplarily described below using a terminal as an example.
[0061] The present application provides a cell switching method. Figure 1 A flowchart of a cell switching method provided by an embodiment of the present application is shown, and the method can be applied to a terminal. Figure 1 As shown, the cell switching method provided in the embodiment of the present application may include the following steps 101 to 103.
[0062] Step 101: The terminal obtains the signal strength of the first cell.
[0063] The first cell may be a service cell of the terminal.
[0064] In some embodiments of the present application, the above-mentioned serving cell may refer to a cell to which the terminal is currently connected and from which it receives services.
[0065] It is understandable that in a mobile communication network, a cell is a basic unit of a wireless communication system, which can be used to provide wireless coverage and capacity and realize wireless communication between a terminal and a network-side device (such as a base station). A cell consists of a network-side device and wireless resources within its coverage area, and its main function is to provide users with reliable communication services by effectively managing and utilizing limited wireless resources.
[0066] In some embodiments of the present application, the above-mentioned signal strength may refer to the level strength of the wireless signal received by the terminal and transmitted by the network side device corresponding to the serving cell.
[0067] In some embodiments of the present application, the signal strength may be affected by multiple factors.
[0068] Exemplarily, the signal strength is affected by the distance between the terminal and the network-side device. The farther the distance between the terminal and the network-side device is, the weaker the signal strength is generally.
[0069] Exemplarily, the signal strength is also affected by obstacles between the terminal and the network-side device. The more obstacles there are between the terminal and the network-side device, the more wireless signals are blocked or absorbed, and the weaker the signal strength.
[0070] For example, signal strength is also affected by weather conditions. Bad weather conditions such as rain and fog may absorb or scatter wireless signals, thereby affecting signal strength.
[0071] Exemplarily, the signal strength is also affected by the transmission power of the network side device. It can be understood that the higher the transmission power of the network side device, the stronger the signal strength is generally.
[0072] Exemplarily, the signal strength is also affected by the receiving sensitivity of the terminal. It can be understood that the higher the receiving sensitivity of the terminal, the stronger the perception of the wireless signal and the stronger the signal strength.
[0073] In some embodiments of the present application, the above signal strength can be measured by some parameters.
[0074] In some embodiments of the present application, the parameters used to measure the signal strength may include but are not limited to: RSRP, Received Signal Strength Indicator (RSSI), and Signal to Interference plus Noise Ratio (SINR).
[0075] In some embodiments of the present application, the above-mentioned RSRP can be used to represent the average power of the reference signal received from the first cell measured by the terminal; the above-mentioned RSSI can be used to represent the signal strength received by the terminal; the above-mentioned SINR can be used to represent the ratio of the strength of the useful signal received by the terminal to the strength of the received interference signal (noise and interference).
[0076] It is understandable that the signal strength can affect the data transmission rate and network coverage.
[0077] Step 102: When the signal strength of the first cell is less than or equal to the first threshold and the first information is received, the terminal does not perform blind redirection and measures the second cell.
[0078] The first information may be used to instruct to measure a second cell, where the network standard of the second cell is different from that of the first cell.
[0079] In some embodiments of the present application, the above-mentioned first information may include information for measuring the second cell configured by the network side device for the terminal.
[0080] Exemplarily, the first information may include a B1 event or a B2 event configured by the network side device for the terminal.
[0081] In some embodiments of the present application, the above-mentioned network standard may refer to the wireless communication technology standard adopted by the cell.
[0082] It is understandable that different network formats may represent different technical specifications and communication protocols, which define key technical parameters such as the transmission method, frequency range, data encoding and decoding method of wireless signals.
[0083] In some embodiments of the present application, the above-mentioned network standards may include but are not limited to: 2G network standard, 3G network standard, 4G network standard, 5G network standard, and 6G network standard.
[0084] In some embodiments of the present application, the above-mentioned blind redirection means that the network side device directly sends a redirection instruction, and the terminal performs the redirection operation without performing a signal measurement and selection process.
[0085] It can be understood that, since this redirection method is performed without signal measurement, this redirection method can be called blind redirection.
[0086] In some embodiments of the present application, the above-mentioned blind redirection process may be: the terminal reports an event that triggers blind redirection; the network side device may send an RRC connection release message carrying designated cell information to the terminal, and the designated cell information may include cell information such as frequency point and scrambling code, to instruct the terminal to release the current RRC connection and attempt to redirect to the designated cell; after receiving the RRC connection release message, the terminal may attempt to access the designated cell according to the designated cell information in the RRC connection release message.
[0087] In some embodiments of the present application, the first threshold may be a threshold value that triggers the terminal to perform blind redirection.
[0088] Exemplarily, the first threshold may be a threshold corresponding to an A2 event with the lowest threshold value among multiple A2 events configured by the network side device for the terminal.
[0089] It should be noted that in order to avoid the situation where the terminal performs blind redirection before switching to the second cell when there is an available second cell, thereby causing interruption of terminal services, the cell switching method provided in the embodiment of the present application may not perform blind redirection first when the signal strength of the first cell is less than or equal to the first threshold, but measure the second cell based on the first information to ensure that when there is an available second cell, the terminal can smoothly switch to the available second cell.
[0090] It can be understood that the above-mentioned available second cell may refer to a cell in which the terminal can reside and obtain normal services.
[0091] In some embodiments of the present application, the terminal can determine whether the cell is available by determining whether the public land mobile network (PLMN) of the terminal matches the PLMN of the cell, whether the cell is set to a prohibited access state, whether the cell belongs to a prohibited roaming area, whether the signal strength of the cell meets the threshold requirement, etc. It can be understood that if the cell meets the above conditions, the cell can usually provide continuous and stable services for the terminal.
[0092] In some embodiments of the present application, the first threshold may be configured by a network-side device or may be specified by a protocol. This embodiment of the present application does not specifically limit this.
[0093] In some embodiments of the present application, Figure 1 ,like Figure 2 As shown, the above step 102 can be specifically implemented through the following step 102a.
[0094] Step 102a: When the signal strength of the first cell is less than or equal to the first threshold and the first information is received, the terminal does not send the third information to the network side device and measures the second cell.
[0095] The third information mentioned above may be used to trigger blind redirection.
[0096] In some embodiments of the present application, the third information may include an event for triggering blind redirection.
[0097] Exemplarily, the first cell is a 5G cell, and the network side device configures 3 A2 events for the terminal. The first A2 event is to trigger the 5G inter-frequency cell measurement when the serving cell RSRP is lower than 105dBm, the second A2 event is to trigger the measurement of the inter-system 4G cell when the serving cell RSRP is lower than -110dBm, and the third A2 event is to trigger the blind redirection to the 5G inter-frequency cell when the serving cell RSRP is lower than -118dBm. Take the third information as an example. That is, when the terminal detects that the serving cell RSRP is lower than -118dBm, the terminal may not report to the network side device that the serving cell RSRP is lower than -118dBm to avoid triggering blind redirection.
[0098] In this way, the terminal can avoid triggering blind redirection by not sending information used to trigger the blind redirection process of the cell to the network side device, so that it can be determined that after the terminal measures an available second cell, it can smoothly switch the serving cell to the available second cell.
[0099] In some embodiments of the present application, Figure 1 ,like Figure 3 As shown, the above step 102 can also be specifically implemented through the following step 102b.
[0100] Step 102b: When the signal strength of the first cell is less than or equal to the first threshold and the first information is received, the terminal measures the second cell and does not perform blind redirection within a first time period.
[0101] In some embodiments of the present application, the first duration may be a delay time for the terminal to perform blind redirection. In other words, the first duration may be a delay time for the terminal to send third information for triggering a blind redirection process of a cell to the network side device.
[0102] Exemplarily, taking the above-mentioned first duration as 1s as an example, when the signal strength of the first cell is less than or equal to the first threshold and the first information is received, the terminal can measure the second cell and not perform blind redirection within 1s. That is, when the signal strength of the first cell is less than or equal to the first threshold and the first information is received, the terminal can measure the second cell and perform blind redirection after 1s.
[0103] For example, assuming that the terminal does not report the A2 event for triggering blind redirection within the first duration, the first duration may be the trigger time of the A2 event timeToTrigger configA2 The terminal can be in the first cell signal strength is less than or equal to the threshold time corresponding to the A2 event for triggering blind redirection reaches timeToTrigger configA2 In this case, report the A2 event.
[0104] In this way, by setting the delay time for executing the blind redirection, it can be ensured that when an available second cell is detected, a smooth handover to the available second cell can be performed before the blind redirection is executed.
[0105] Step 103: When the measurement result of the second cell meets the reporting condition, the terminal sends second information to the network side device.
[0106] The second information may be used to trigger switching of the service cell of the terminal from the first cell to the second cell.
[0107] In some embodiments of the present application, the second information may include a B1 event or a B2 event.
[0108] In some embodiments of the present application, the terminal may complete the switching of the serving cell by reporting a B1 event or a B2 event.
[0109] In some embodiments of the present application, the above-mentioned reporting conditions may include: the signal strength of the second cell measured by the terminal is greater than or equal to the second threshold, and the duration for which the signal strength of the second cell measured by the terminal is greater than or equal to the second threshold is greater than a third threshold.
[0110] In some embodiments of the present application, the third threshold may be smaller than the value of the first duration.
[0111] In some embodiments of the present application, the third threshold may be a trigger time for reporting the second information: timeToTrigger configB .
[0112] In some embodiments of the present application, the signal strength of the second cell measured by the above terminal is greater than or equal to the second threshold, and the duration of the signal strength of the second cell measured by the terminal being greater than or equal to the second threshold is greater than the third threshold, which can indicate that the second cell signal is good and stable. At this time, the terminal can send second information to the network side device to switch the serving cell from the first cell to the second cell.
[0113] It is understandable that the measurement result of the second cell meeting the reporting condition may indicate that the second cell is available. Therefore, the terminal may send second information to the network side device to switch the serving cell of the terminal from the first cell to the second cell.
[0114] In some embodiments of the present application, the third threshold may be the value of the first duration. It is understood that the duration during which the signal strength of the second cell measured by the terminal is greater than or equal to the second threshold is less than the first duration, which can ensure that the second information is reported before the terminal starts the blind redirection process.
[0115] In some embodiments of the present application, the third threshold may be configured by a network side device, may be specified by a protocol, or may be a default threshold of an endpoint. The present application does not specifically limit this.
[0116] In some embodiments of the present application, the third threshold may also be 0.
[0117] It can be understood that in order to report the measurement results of the second cell as soon as possible, the terminal can immediately report the second information when the signal strength of the second cell measured is greater than or equal to the second threshold, that is, the third threshold is 0, so as to switch the service cell from the first cell to the second cell before the terminal performs blind redirection.
[0118] The cell switching method provided in the embodiment of the present application, when the signal strength of the service cell of the terminal reaches the threshold value for triggering blind redirection, if the terminal receives indication information for measuring a cell of a different network standard, the terminal may not first execute the blind redirection process of the cell. Instead, when the measurement determines that the cell of the different network standard is available, the terminal's service cell is first switched to the cell of the different network standard, so as to avoid the terminal from executing blind redirection when the terminal measures and searches for an available cell, thereby maintaining terminal service continuity and avoiding freezes.
[0119] In some embodiments of the present application, the above step 103 may include the following step 103a.
[0120] In step 103a, when the measurement result of the second cell meets the reporting condition, the terminal accelerates sending the second information to the network side device.
[0121] In some embodiments of the present application, the terminal may accelerate the sending of the second information to the network side device by reducing as much as possible the duration during which the measured signal strength of the second cell is greater than or equal to the second threshold.
[0122] In some embodiments of the present application, the terminal may also accelerate the sending of the second information to the network side device by optimizing data format, information grouping and aggregation, etc. The embodiments of the present application are not specifically limited.
[0123] In this way, when the measurement result of the second cell meets the reporting conditions, the terminal can accelerate the sending of the second information to the network side device, thereby ensuring that the information of switching to the available second cell can be reported before the information triggering blind redirection, avoiding terminal service interruption.
[0124] Each of the above-mentioned method embodiments, or various possible implementation methods in each method embodiment, can be executed separately, or any two or more of them can be executed in combination with each other. The specific implementation method can be determined according to actual usage requirements, and the embodiments of the present application do not limit this.
[0125] The cell switching method provided in the embodiment of the present application is exemplified below with specific examples.
[0126] Example 1: Figure 4 As shown, the cell switching method may include the following steps 201 to 209.
[0127] Step 201: After the terminal resides in the 5G service cell, the network side device configures A1 event and A2 event for the terminal.
[0128] Among them, the 5G service cell is the first cell mentioned above.
[0129] The above A2 event may include the first A2 event, the second A2 event and the third A2 event. The first A2 event is to trigger the 5G inter-frequency cell measurement when the serving cell RSRP is lower than 105dBm, the second A2 event is to trigger the measurement of the inter-system 4G cell when the serving cell RSRP is lower than -110dBm, and the third A2 event is to trigger the blind redirection to the 5G inter-frequency cell when the serving cell RSRP is lower than -118dBm.
[0130] Step 202: When the terminal detects that the signal strength of the 5G service cell is less than or equal to the reporting threshold corresponding to the first A2 event, the terminal reports the first A2 event.
[0131] Step 203: After receiving the first A2 event reported by the terminal, the network side device configures an A3 event for the terminal.
[0132] Step 204: When the terminal detects that the signal strength of the 5G service cell is less than or equal to the reporting threshold of the second A2 event, the terminal reports the second A2 event.
[0133] Step 205: After receiving the second A2 event reported by the terminal, the network side device configures a B event for the terminal.
[0134] The B event may include a B1 event or a B2 event. The B event may include a corresponding RSRP threshold.
[0135] Step 206: When the terminal detects that the signal strength of the 5G service cell is less than or equal to the reporting threshold of the third A2 event, the terminal does not report the third A2 event and measures the 4G cell.
[0136] Among them, the reporting threshold of the third A2 event is the above-mentioned first threshold; the 4G cell is the above-mentioned second cell; the terminal does not report the third A2 event, which may indicate that the terminal does not perform blind redirection.
[0137] It can be understood that after receiving the B event configured by the network side device, the terminal can perform measurements of 4G cells of different systems. During this period, the terminal can report the third A2 event (i.e., the A2 event with the lowest reporting threshold) to ensure that the B event can be sent smoothly to the network side device.
[0138] Step 207: When the signal strength of the 4G cell meets the RSRP threshold corresponding to the B event, the terminal reports the B event.
[0139] Among them, event B is the above-mentioned second information; the signal strength of the 4G cell meets the RSRP threshold corresponding to event B, which is the above-mentioned reporting condition.
[0140] Step 208: After receiving event B, the network side device sends cell switching indication information to the terminal.
[0141] Step 209: The terminal receives the cell switching indication information and switches the service cell from the 5G service cell to the 4G cell.
[0142] In this way, by not reporting the lowest A2 event, the terminal can be ensured to switch to the 4G cell in an environment where the 4G cell is available, thereby avoiding interruption of terminal services.
[0143] Example 2: Figure 5 As shown, the cell switching method may include the following steps 301 to 309.
[0144] Step 301: After the terminal resides in the 5G service cell, the network side device configures A1 event and A2 event for the terminal.
[0145] Among them, the 5G service cell is the first cell mentioned above.
[0146] The above A2 event may include the first A2 event, the second A2 event and the third A2 event. The first A2 event is to trigger the 5G inter-frequency cell measurement when the serving cell RSRP is lower than 105dBm, the second A2 event is to trigger the measurement of the inter-system 4G cell when the serving cell RSRP is lower than -110dBm, and the third A2 event is to trigger the blind redirection to the 5G inter-frequency cell when the serving cell RSRP is lower than -118dBm.
[0147] Step 302: When the terminal detects that the signal strength of the 5G service cell is less than or equal to the reporting threshold corresponding to the first A2 event, the terminal reports the first A2 event.
[0148] Step 303: After receiving the first A2 event reported by the terminal, the network side device configures an A3 event for the terminal.
[0149] Step 304: When the terminal detects that the signal strength of the 5G service cell is less than or equal to the reporting threshold of the second A2 event, the terminal reports the second A2 event.
[0150] Step 305: After receiving the second A2 event reported by the terminal, the network side device configures a B event for the terminal.
[0151] The B event may include a B1 event or a B2 event. The B event may include a corresponding RSRP threshold and timeToTriggerb configuration.
[0152] Step 306: When the terminal detects that the signal strength of the 5G serving cell is less than or equal to the reporting threshold of the third A2 event, the terminal measures the 4G cell and reports the signal strength of the 5G serving cell at timeToTrigger. configA2 The third A2 event will not be reported.
[0153] Among them, timeToTrigger configA2 This is the first duration mentioned above (such as timeToTrigger configA2 =1s), the reporting threshold of the third A2 event is the above-mentioned first threshold; the 4G cell is the above-mentioned second cell; the terminal does not report the third A2 event, which may indicate that the terminal does not perform blind redirection.
[0154] It can be understood that after receiving the B event configured by the network side device, the terminal can perform measurements of 4G cells of different systems. During this period, the terminal can report the third A2 event (i.e., the A2 event with the lowest reporting threshold) to ensure that the B event can be sent smoothly to the network side device.
[0155] Step 307: After the signal strength of the terminal in the 4G cell meets the RSRP threshold corresponding to the B event for a period of timeToTriggerb, the terminal reports the B event.
[0156] Among them, event B is the above-mentioned second information; the signal strength of the 4G cell meets the RSRP threshold corresponding to event B and reaches timeToTriggerb, which is the above-mentioned reporting condition.
[0157] Step 308: After receiving event B, the network side device sends cell switching indication information to the terminal.
[0158] Step 309: The terminal receives the cell switching indication information and switches the service cell from the 5G service cell to the 4G cell.
[0159] Thus, by customizing the timeToTrigger of the minimum A2 event configA2 , the terminal can switch to the 4G cell normally to avoid interruption of terminal services.
[0160] Example 3: Figure 6 As shown, the cell switching method may include the following steps 401 to 409.
[0161] Step 401: After the terminal resides in the 5G service cell, the network side device configures A1 event and A2 event for the terminal.
[0162] Among them, the 5G service cell is the first cell mentioned above.
[0163] The above A2 event may include the first A2 event, the second A2 event and the third A2 event. The first A2 event is to trigger the 5G inter-frequency cell measurement when the serving cell RSRP is lower than 105dBm, the second A2 event is to trigger the measurement of the inter-system 4G cell when the serving cell RSRP is lower than -110dBm, and the third A2 event is to trigger the blind redirection to the 5G inter-frequency cell when the serving cell RSRP is lower than -118dBm.
[0164] Step 402: When the terminal detects that the signal strength of the 5G service cell is less than or equal to the reporting threshold corresponding to the first A2 event, the terminal reports the first A2 event.
[0165] Step 403: After receiving the first A2 event reported by the terminal, the network side device configures an A3 event for the terminal.
[0166] Step 404: When the terminal detects that the signal strength of the 5G service cell is less than or equal to the reporting threshold of the second A2 event, the terminal reports the second A2 event.
[0167] Step 405: After receiving the second A2 event reported by the terminal, the network side device configures a B event for the terminal.
[0168] The B event may include a B1 event or a B2 event. The B event may include a corresponding RSRP threshold and a timeToTriggerconfigB configuration.
[0169] Step 406: When the terminal detects that the signal strength of the 5G service cell is less than or equal to the reporting threshold of the third A2 event, the terminal does not report the third A2 event and measures the 4G cell.
[0170] Among them, the reporting threshold of the third A2 event is the above-mentioned first threshold; the 4G cell is the above-mentioned second cell; the terminal does not report the third A2 event, which may indicate that the terminal does not perform blind redirection.
[0171] It can be understood that after receiving the B event configured by the network side device, the terminal can perform measurements of 4G cells of different systems. During this period, the terminal can report the third A2 event (i.e., the A2 event with the lowest reporting threshold) to ensure that the B event can be sent smoothly to the network side device.
[0172] Step 407: The signal strength of the terminal in the 4G cell meets the RSRP threshold corresponding to event B and the duration reaches timeToTrigger configB Afterwards, report event B.
[0173] Among them, timeToTrigger configBThat is the third threshold mentioned above (such as timeToTrigger configB =0s), event B is the second information mentioned above; the signal strength of the 4G cell meets the RSRP threshold corresponding to event B and reaches timeToTriggerb, which is the reporting condition mentioned above.
[0174] Step 408: After receiving event B, the network side device sends cell switching indication information to the terminal.
[0175] Step 409: The terminal receives the cell switching indication information and switches the service cell from the 5G service cell to the 4G cell.
[0176] So, by customizing the timeToTrigger of event B configB , the terminal can switch to the 4G cell normally to avoid interruption of terminal services.
[0177] Example 3: Figure 7 As shown, the cell switching method may include the following steps 501 to 509.
[0178] Step 501: After the terminal resides in the 5G service cell, the network side device configures A1 event and A2 event for the terminal.
[0179] Among them, the 5G service cell is the first cell mentioned above.
[0180] The above A2 event may include the first A2 event, the second A2 event and the third A2 event. The first A2 event is to trigger the 5G inter-frequency cell measurement when the serving cell RSRP is lower than 105dBm, the second A2 event is to trigger the measurement of the inter-system 4G cell when the serving cell RSRP is lower than -110dBm, and the third A2 event is to trigger the blind redirection to the 5G inter-frequency cell when the serving cell RSRP is lower than -118dBm.
[0181] Step 502: When the terminal detects that the signal strength of the 5G service cell is less than or equal to the reporting threshold corresponding to the first A2 event, the terminal reports the first A2 event.
[0182] Step 503: After receiving the first A2 event reported by the terminal, the network side device configures an A3 event for the terminal.
[0183] Step 504: When the terminal detects that the signal strength of the 5G service cell is less than or equal to the reporting threshold of the second A2 event, the terminal reports the second A2 event.
[0184] Step 505: After receiving the second A2 event reported by the terminal, the network side device configures a B event for the terminal.
[0185] The B event may include a B1 event or a B2 event. The B event may include a corresponding RSRP threshold and a timeToTriggerconfigB configuration.
[0186] Step 506: When the terminal detects that the signal strength of the 5G serving cell is less than or equal to the reporting threshold of the third A2 event, the terminal measures the 4G cell and reports the signal strength of the 5G serving cell at timeToTrigger. configA2 The third A2 incident will not be reported within 24 hours.
[0187] Among them, timeToTrigger configA2 This is the first duration mentioned above (such as timeToTrigger configA2 =1s), the reporting threshold of the third A2 event is the above-mentioned first threshold; the 4G cell is the above-mentioned second cell; the terminal does not report the third A2 event, which may indicate that the terminal does not perform blind redirection.
[0188] It can be understood that after receiving the B event configured by the network side device, the terminal can perform measurements of 4G cells of different systems. During this period, the terminal can report the third A2 event (i.e., the A2 event with the lowest reporting threshold) to ensure that the B event can be sent smoothly to the network side device.
[0189] Step 507: The signal strength of the terminal in the 4G cell meets the RSRP threshold corresponding to event B and the duration reaches timeToTrigger configB Afterwards, report event B.
[0190] Among them, timeToTrigger configB That is the third threshold mentioned above (such as timeToTrigger configB =0s), event B is the second information mentioned above; the signal strength of the 4G cell meets the RSRP threshold corresponding to event B and reaches timeToTriggerb, which is the reporting condition mentioned above.
[0191] Step 508: After receiving event B, the network side device sends cell switching indication information to the terminal.
[0192] Step 509: The terminal receives the cell switching indication information and switches the service cell from the 5G service cell to the 4G cell.
[0193] Thus, by customizing the timeToTrigger of the minimum A2 event configA2 and timeToTrigger of event B configB , the terminal can switch to the 4G cell normally to avoid interruption of terminal services.
[0194] The cell switching method provided in the embodiment of the present application may be executed by a cell switching device. In the embodiment of the present application, the cell switching device provided in the embodiment of the present application is described by taking the cell switching method executed by the cell switching device as an example.

When the signal strength of the service cell of the cell switching device reaches a threshold value for triggering blind redirection, if the cell switching device receives instruction information for measuring a cell of a different network standard, the cell switching device may not perform blind redirection first. Instead, when the measurement determines that the cell of the different network standard is available, the cell switching device may first switch the service cell of the cell switching device to the cell of the different network standard, so as to ensure that the cell switching device maintains service continuity when switching the service cell and avoids jamming.

To avoid repetition, it will not be repeated here.
[0206] It should be noted that the terminals in the embodiments of the present application include the mobile terminals and non-mobile terminals mentioned above.
