Description

Technical Field

[0001] This application relates to, but is not limited to, the field of communication technology, and in particular to a cell blocking method, apparatus, terminal device, and computer storage medium. Background Technology

[0002] When a terminal device is within network coverage, it should stay in the cell as much as possible, access the network, and request network services.

[0003] In related technologies, when a terminal device receives a rejection message from the first network device corresponding to the first Tracking Area Code (TAC), the terminal device will add the first TAC to the Forbidden Tracking Areas for Roaming list, thereby disabling the first TAC. This setting can only be periodically cleared after 12 to 24 hours before the device is powered off or the Subscriber Identity Module (SIM) is removed. During the period when the first TAC is disabled, the terminal device will be unable to camp on any cell under the first TAC, reducing communication reliability. Summary of the Invention

[0004] This application provides a method, apparatus, terminal device, and computer storage medium for disabling a cell.

[0005] In a first aspect, embodiments of this application provide a cell disabling method, including:

[0006] If a terminal device receives a rejection message from a first network device corresponding to a first tracking area code (TAC), and if at least one of the cells that have been successfully registered / attached / camped to by the first TAC includes cells other than the first cell corresponding to the first network device, the terminal device disables the first cell.

[0007] Secondly, embodiments of this application provide a cell disabling device, comprising:

[0008] The disabling unit is configured to disable the first cell if, when the terminal device receives a rejection message sent by the first network device corresponding to the first tracking area code (TAC), at least one of the cells that have been successfully registered / attached / camped to the first TAC includes other cells besides the first cell corresponding to the first network device.

[0009] Thirdly, embodiments of this application provide a terminal device, including: a memory and a processor.

[0010] The memory is used to store computer programs.

[0011] The processor is used to call and run the computer program stored in the memory, causing the terminal device to perform the method described in the first aspect.

[0012] Fourthly, embodiments of this application provide a computer storage medium storing one or more programs, which can be executed by one or more processors to implement the method described in the first aspect.

[0013] In this embodiment, when a terminal device receives a rejection message from a first network device corresponding to a first tracking area code (TAC), if at least one of the cells that have been successfully registered / attached / camped to the first TAC includes cells other than the first cell corresponding to the first network device, the terminal device disables the first cell. Thus, when the terminal device receives a rejection message from the first network device corresponding to the first TAC, it does not need to disable the first TAC as in related technologies; it only needs to disable the first cell corresponding to the first network device. This allows the terminal device to camp on other cells besides the first cell, thereby improving communication reliability. Attached Figure Description

It should also be understood that in the embodiments of this application, the "protocol" can refer to standard protocols in the field of communication, such as the LTE protocol, the NR protocol, and related protocols applied to future communication systems, and this application does not limit this.

[0035] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0036] When a terminal device receives a network rejection code, it will process it according to the 3rd Generation Partnership Project (3GPP) Non-Access Stratum (NAS) protocol. For example, in some embodiments, for a rejection code with reason value #15 received when the terminal device fails to register / attach / reside, the terminal device will add the current cell's TAC to the Tracking Area Identity (TAI) disabled list, Tracking Area Code (TAC) disabled list, or prohibited TA list. This setting can only be periodically cleared after 12 to 24 hours before the device is powered off or the SIM card is removed. This process is followed for single-SIM terminals, and for dual-SIM terminals, the processing procedure for each SIM card is also followed.

[0037] However, if the rejection code with reason value #15 is caused by a temporary problem in the core network, then all cell terminal devices under the TAC will be unable to camp. If there are no other cells under the current TAC, the terminal devices will be unable to camp on the cell under the corresponding standard of the TAC, thus accessing cells under other standards, resulting in reduced communication performance.

[0038] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0039] In this embodiment of the application, when the terminal device receives a rejection message sent by the first network device corresponding to the first tracking area code (TAC), the terminal device disables the first cell corresponding to the first network device.

[0040] Figure 2 This is a schematic diagram illustrating the implementation process of a cell disabling method provided in an embodiment of this application, as shown below. Figure 2 As shown, this method is applied to a terminal device, and the method includes:

[0041] S201. If the terminal device receives a rejection message sent by the first network device corresponding to the first tracking area code (TAC), and if at least one of the cells that have been successfully registered / attached / camped to the first TAC includes other cells besides the first cell corresponding to the first network device, the terminal device disables the first cell.

[0042] In some embodiments, a TAC may correspond to one or more cells or one or more network devices. In any embodiment of this application, one cell may correspond to one network device.

[0043] In some embodiments, the terminal device may send a request to the first network device and receive a rejection message from the first network device. In any embodiment of this application, unless otherwise specified, the request may include: a registration request, an attachment request, an update request, or a service request.

[0044] In some embodiments, the terminal device can send a request to the first network device via signaling in the registration process (5G standard), signaling in the attach process (4G standard), or signaling corresponding to other standards (such as 6G, 7G, etc.), and receive a rejection message from the first network device. In some embodiments, taking signaling in the 5G standard as an example, the terminal device can send a Registration Request, Combined Registration Request, Mobility Registration Updating (MRU) Request, Combined MRU Request, or Service Request to the first network device and receive a rejection message from the first network device. In other embodiments, taking signaling in the 4G standard as an example, the terminal device can send an Attach Request, Combined Attach Request, Tracking Area Update (TAU) Request, Combined TAU Request, or Service Request to the first network device and receive a rejection message from the first network device.

[0045] In some embodiments, the terminal device sending a request to the first network device may include at least one of the following: the terminal device sending a request to the first network device using information corresponding to the first SIM (or, the terminal device sending a first SIM correspondence request to the first network device); or the terminal device sending a request to the first network device using information corresponding to the second SIM (or, the terminal device sending a second SIM correspondence request to the first network device). In some embodiments, the terminal device receiving a rejection message from the first network device may include at least one of the following: the terminal device receiving a rejection message corresponding to the first SIM from the first network device; or the terminal device receiving a rejection message corresponding to the second SIM from the first network device.

[0046] In any embodiment of this application, the information corresponding to the first SIM / second SIM may include at least one of the following: the International Mobile Subscriber Identity (IMSI) corresponding to the first SIM / second SIM, the Globally Unique Temporary Identity (GUTI) corresponding to the first SIM / second SIM, the International Mobile Equipment Identity (IMEI) corresponding to the first SIM / second SIM, the Temporary Mobile Subscriber Identity (TMSI) corresponding to the first SIM / second SIM, the Packet-Temporary Mobile Subscriber Identity (P-TMSI) corresponding to the first SIM / second SIM, and the user's mobile phone number corresponding to the first SIM / second SIM.

[0047] In some embodiments, the rejection information may include a rejection code. For example, the rejection code may include one of the following: reason value #3, reason value #7, reason value #11, reason value #12, reason value #13, reason value #15, reason value #22, reason value #27, reason value #62, reason value #72, reason value #73, reason value #74, reason value #75, reason value #31, reason value #76, reason value #77, reason value #96, reason value #99, reason value #100, reason value #111, reason value #9, reason value #10. Exemplarily, in some embodiments of this application, the rejection code may include reason value #15. It should be noted that this application does not limit the content of the rejection code; in other embodiments, the rejection code may also include other rejection codes besides those listed herein.

[0048] In some embodiments, the terminal device may store at least one successfully registered / attached / camped cell corresponding to the first TAC, thereby enabling the terminal device to read the at least one successfully registered / attached / camped cell corresponding to the first TAC from the storage space. During implementation, the system may set the first TAC to correspond to A cells, and the terminal device may store at least B cells corresponding to the first TAC that have been successfully registered / attached / camped. The B cells may belong to the A cells, where A and B are both integers greater than or equal to 1, and B is less than or equal to A.

[0049] In some embodiments, at least one cell that has been successfully registered / attached / camped to by the first TAC may include at least one cell in which the terminal device corresponding to the first TAC has been successfully registered / attached / camped to.

[0050] In other embodiments, at least one cell that has been successfully registered / attached / camped to corresponding to the first TAC, or at least one cell that has been successfully registered / attached / camped to corresponding to the terminal device of the first TAC, may include: at least one cell that has been successfully registered / attached / camped to corresponding to at least one SIM of the terminal device and the first TAC. In any embodiment of this application, at least one SIM includes a first SIM and / or a second SIM. It should be noted that in other embodiments, at least one SIM may include other numbers of SIMs. For example, at least one SIM may include a first SIM, or at least one SIM may include at least one of the following: a first SIM and / or a second SIM and / or a third SIM, etc., which are not listed here.

[0051] In some other embodiments, the at least one cell that has been successfully registered / attached / camped to corresponding to the first TAC may include: at least one cell where the terminal device corresponding to the first TAC has been successfully registered / attached / camped to, and / or at least one cell where other devices corresponding to the first TAC have been successfully registered / attached / camped to. In any embodiment of this application, the other devices may be one or more devices other than the terminal device. In any embodiment of this application, the other devices may be devices capable of communicating with the terminal device. For example, the terminal device may be a mobile phone, and the other devices may be a watch.

[0052] In some embodiments, disabling a first cell by a terminal device may include: the terminal device storing the cell information of the first cell in storage space or a cell disable list; or, the terminal device storing the cell information of the first cell and the disable time of the first cell in storage space or a cell disable list. In any embodiment of this application, the cell information may include at least one of the following: cell ID, E-UTRA Absolute Radio Frequency Channel Number (EARFCN), Physical Cell Identifier (PCI), and registration result. In some embodiments, the registration result may include ()registration / attachment / camping successful or ()registration / attachment / camping failed, and the registration result corresponding to ()registration / attachment / camping failure may include a reason value. In some embodiments, the disable time of the first cell may include at least one of the following: the disable start time of the first cell, the disable duration of the first cell, and the disable end time of the first cell.

[0053] In some embodiments, the terminal device may store cell information for each cell that initiates registration.

[0054] For example, if registration of a first specific cell fails, the terminal device can record the registration result for that first specific cell as registration failure. If the registration of the first specific cell is successful later, the terminal device can incorporate the registration success information into the cell information of the first specific cell. In this way, the registration result in the cell information of the first specific cell includes both registration failure and registration success. Alternatively, the terminal device can replace the registration result of the first specific cell as registration failure with registration success. In this way, the registration result in the cell information of the first specific cell includes registration success.

[0055] For example, if a second specific cell is successfully registered, the terminal device can record the registration result for that second specific cell as "registration successful". If the registration fails in the subsequent second specific cell, the terminal device can incorporate the registration failure information into the cell information of that second specific cell. In this way, the registration result in the cell information of the second specific cell includes both registration failure and registration success. Alternatively, the terminal device can replace "registration successful" with "registration failure" for the second specific cell. In this way, the registration result in the cell information of the second specific cell includes registration failure. Or, the terminal device can leave the registration result of the second specific cell unchanged. In this way, the registration result in the cell information of the second specific cell includes registration success.

[0056] In other embodiments, the terminal device may store the registration result for each registration of a specific cell, or the registration result for each registration of a specific cell and the time when the registration result was generated. In still other embodiments, the terminal device stores the registration result for each specific cell as either registration success or registration failure, where successful registration indicates that at least one registration was successful in the historical registration process, and registration failure indicates that every registration in the historical registration process failed.

[0057] In some embodiments, the first cell may or may not be included among the at least one cell that has been successfully registered / attached / resided to the first TAC.

[0058] In some embodiments, when the terminal device disables the first cell, the terminal device can initiate a registration / attachment process to one of the other cells to camp on that cell. In other embodiments, the terminal device can determine a target cell based on measurement results of M cells other than the first cell, and initiate a registration / attachment process to the target cell to camp on it. Here, M is an integer greater than or equal to 1. In some embodiments, the measurement result of the target cell can be the largest measurement result among the M cell measurement results, or the measurement result of the target cell can be a measurement result greater than a first threshold among the M cell measurement results. In some embodiments, before sending a request to the first network device, the terminal device can determine the first cell based on measurement results of N cells, and initiate a registration / attachment process to the first cell to camp on it. Here, N is an integer greater than or equal to 1. In some embodiments, the measurement result of the first cell can be the largest measurement result among the N cell measurement results, or the measurement result of the first cell can be a measurement result greater than a second threshold among the N cell measurement results. In some embodiments, the first threshold can be less than the second threshold, or the first threshold can be equal to the second threshold. In some embodiments, the measurement results may include at least one of the following: Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Received Signal Strength Indicator (RSSI), and Signal to Interference plus Noise Ratio (SINR).

[0059] In some embodiments, when the terminal device disables the first cell, the terminal device may record the cell information of the first cell. For example, if the terminal device has already recorded the first TAC, it records the cell information of the first cell corresponding to the first TAC. Also for example, if the terminal device has not recorded the first TAC, it records the first TAC and the cell information of the first cell corresponding to the first TAC. For example, the registration result recorded in the cell information of the first cell by the terminal device is "registration failed".

[0060] In some embodiments, after the terminal device disables the first cell, the terminal device can access other cells through cell information of other cells, or initiate registration or attachment to the network device corresponding to other cells.

[0061] In this embodiment, when a terminal device receives a rejection message from a first network device corresponding to a first tracking area code (TAC), if at least one of the cells that have been successfully registered / attached / camped to the first TAC includes cells other than the first cell corresponding to the first network device, the terminal device disables the first cell. Thus, when the terminal device receives a rejection message from the first network device corresponding to the first TAC, it does not need to disable the first TAC as in related technologies; it only needs to disable the first cell corresponding to the first network device. This allows the terminal device to camp on other cells besides the first cell, thereby improving communication reliability.

[0062] In some embodiments, if a terminal device receives a rejection message from a first network device corresponding to a first tracking area code (TAC), and if at least one of the cells that have been successfully registered / attached / camped to the first TAC includes the first cell corresponding to the first network device, the terminal device may resend the request to the first network device.

[0063] In some embodiments, after the terminal device resends the request to the first network device, if it successfully registers / attaches / camps in the first cell, for example, if the terminal device receives the acceptance information sent by the first network device, the terminal device does not need to block the first cell or the first TAC, and can still communicate with the first network device.

[0064] In other embodiments, if the terminal device receives a rejection message from the first network device after resending the request to the first network device, and if at least one of the cells that have successfully registered / attached / camped with the first TAC includes cells other than the first cell corresponding to the first network device, the terminal device disables the first cell; or, if the first TAC is not included in at least one of the cells that have successfully registered / attached / camped with the first TAC, the terminal device disables the first TAC; or, if at least one of the cells that have successfully registered / attached / camped with the first TAC does not include cells other than the first cell corresponding to the first network device, the terminal device disables the first TAC; or, if one or more cells corresponding to the first TAC are cells that have failed to register / attach / camp, the terminal device disables the first TAC.

[0065] Figure 3 This is a schematic diagram illustrating the implementation process of another cell disabling method provided in an embodiment of this application, as shown below. Figure 3 As shown, this method is applied to a terminal device, and the method includes:

[0066] S301. When the terminal device receives a rejection message sent by the first network device corresponding to the first tracking area code (TAC), the terminal device determines that the first TAC is included among at least one TAC that has been successfully registered / attached / resided.

[0067] In some embodiments, the terminal device may store at least one TAC that has been successfully registered / attached / residing, so that the terminal device can read at least one TAC that has been successfully registered / attached / residing from the storage space.

[0068] In some embodiments, at least one successfully registered / attached / resided TAC may include at least one TAC that has been successfully registered / attached / resided by the terminal device. In other embodiments, at least one successfully registered / attached / resided TAC may include at least one TAC that has been successfully registered / attached / resided by at least one SIM card of the terminal device. In still other embodiments, at least one successfully registered / attached / resided TAC may include at least one TAC that has been successfully registered / attached / resided by the terminal device, and / or at least one TAC that has been successfully registered / attached / resided by other devices.

[0069] S302, the terminal device determines at least one cell that has been successfully registered / attached / resided to the first TAC.

[0070] In some embodiments, the terminal device obtains a first correspondence; the first correspondence includes: a correspondence between each of a plurality of TACs and at least one cell that has been successfully registered / attached / camped and / or at least one cell that has failed to be registered / attached / camped; the terminal device can determine the at least one cell that has been successfully registered / attached / camped corresponding to the first TAC based on the first correspondence and the first TAC. In some embodiments, the first correspondence may be stored in the terminal device.

[0071] S303. If at least one of the cells that have been successfully registered / attached / camped to by the first TAC includes cells other than the first cell corresponding to the first network device, the terminal device disables the first cell.

[0072] For example, if at least one successfully registered / attached / camped cell corresponding to the first TAC includes cell B and cell C, and the first cell is cell A, the terminal device disables cell A. Also for example, if at least one successfully registered / attached / camped cell corresponding to the first TAC includes cell B and cell C, and the first cell is cell B, the terminal device disables cell B.

[0073] The following explains the situation where the first TAC is disabled on the terminal device:

[0074] In some embodiments, if a terminal device receives a rejection message from a first network device corresponding to a first tracking area code (TAC), and the first TAC is not included in at least one TAC that has been successfully registered / attached / resided, the terminal device disables the first TAC.

[0075] In other embodiments, if the terminal device receives a rejection message from the first network device corresponding to the first tracking area code (TAC), and if none of the at least one successfully registered / attached / camped cells corresponding to the first TAC include any other cells besides the first cell corresponding to the first network device, the terminal device disables the first TAC.

[0076] In this scenario, if the terminal device receives a rejection message from the first network device corresponding to the first tracking area code (TAC), and if the first TAC is included in at least one TAC that has been successfully registered / attached / camped, but the at least one cell that has been successfully registered / attached / camped to the first TAC does not include any other cells besides the first cell corresponding to the first network device, the terminal device disables the first TAC.

[0077] For example, if the at least one cell that has successfully registered / attached / camped with the first TAC does not include any cells other than the first cell corresponding to the first network device, it may include only the first cell among the at least one cell that has successfully registered / attached / camped with the first TAC. In this case, the first TAC may have one or more cells that have failed to register / attach / camped with it, or it may not have one or more cells that have failed to register / attach / camped with it.

[0078] In some other embodiments, if a terminal device receives a rejection message from a first network device corresponding to a first tracking area code (TAC), and if one or more cells corresponding to the first TAC are cells that have failed to register / attach / stay, the terminal device disables the first TAC.

[0079] For example, if the first TAC corresponds to one or more successfully registered / attached / resided cells including cell C and cell D, and the first cell is cell A, the terminal device disables the first TAC; or, if the first cell is cell C, the terminal device disables the first TAC.

[0080] In some embodiments, when the terminal device disables the first TAC, the terminal device may record the cell information of the first cell. For example, if the terminal device has already recorded the first TAC, it records the cell information of the first cell corresponding to the first TAC. Also for example, if the terminal device has not recorded the first TAC, it records the first TAC and the cell information of the first cell corresponding to the first TAC.

[0081] In some embodiments, disabling the first TAC by the terminal device may include: the terminal device disabling the first TAC for a second period of time. During the period of disabling the first TAC, the terminal device cannot initiate registration / attachment to the cell under the first TAC.

[0082] In some embodiments, disabling the first TAC on the terminal device may include: the terminal device adding the first TAC to the blocked TAC list, and periodically clearing this setting only after 12 to 24 hours before powering off or removing the corresponding SIM (e.g., when the terminal device receives a rejection message for the first SIM from the first network device, where the SIM is the first SIM, and / or when the terminal device receives a rejection message for the second SIM from the first network device, where the SIM is the second SIM). Thus, the terminal device will only be able to remove the first TAC from the blocked TAC list, or release the disabled first TAC, or be able to use the first TAC, or be able to initiate registration / attachment to the cell under the first TAC, after 12 to 24 hours.

[0083] In some embodiments, at least one cell that has been successfully registered / attached / camped to corresponding to the first TAC includes: at least one cell that has been successfully registered / attached / camped to corresponding to the first user identification module SIM and / or the second SIM of the terminal device and the first TAC.

[0084] In some embodiments, the first SIM and the second SIM can belong to the same operator. For example, both the first SIM and the second SIM may belong to China Mobile or both may belong to China Unicom.

[0085] For example, when a terminal device receives a rejection message sent by a first network device corresponding to a first TAC, the at least one cell that has been successfully registered / attached / camped with the first TAC includes: at least one cell that has been successfully registered / attached / camped with the first TAC and / or the second SIM of the terminal device.

[0086] In other embodiments, at least one cell that has been successfully registered / attached / camped to by the first TAC may include: at least one cell in which the terminal device corresponding to the first TAC has been successfully registered / attached / camped to, and / or at least one cell in which other devices corresponding to the first TAC have been successfully registered / attached / camped to.

[0087] For example, at least one cell that has been successfully registered / attached / camped to corresponding to the first TAC, or at least one cell that has been successfully registered / attached / camped to corresponding to the terminal device of the first TAC, may include: at least one cell that has been successfully registered / attached / camped to corresponding to at least one SIM of the terminal device and the first TAC. For example, at least one cell that has been successfully registered / attached / camped to corresponding to the first TAC by other devices may include: at least one cell that has been successfully registered / attached / camped to corresponding to at least one SIM of the other device and the first TAC.

[0088] In some embodiments, the terminal device may store a target list of registered / attached / camped cells (which may include a database described below), the target list including at least one cell that has successfully registered / attached / camped with the terminal device and corresponds to the first TAC. In other embodiments, the target list may further include at least one cell that has failed to register / attach / camped with the terminal device and corresponds to the first TAC. In still other embodiments, the target list may further include at least one TAC that has successfully registered / attached / camped with the terminal device. In yet another embodiment, the target list may further include cell information for each cell.

[0089] Figure 4 This is a schematic diagram illustrating the implementation process of another cell disabling method provided in an embodiment of this application, as shown below. Figure 4 As shown, this method is applied to a terminal device, and the method includes:

[0090] S401. When the terminal device receives a rejection message sent by the first network device corresponding to the first tracking area code (TAC), the terminal device obtains a first correspondence relationship; the first correspondence relationship includes: the correspondence relationship between each of the plurality of TACs and at least one cell that has been successfully registered / attached / camped and / or at least one cell that has failed to be registered / attached / camped.

[0091] In some embodiments, the terminal device may obtain a first correspondence from its own storage space.

[0092] S402. The terminal device determines, based on the first correspondence, at least one cell that has been successfully registered / attached / camped to by the first TAC, including other cells besides the first cell corresponding to the first network device.

[0093] In some embodiments, where the first correspondence includes the correspondence between each TAC and at least one cell that has been successfully registered / attached / camped, the terminal device determines at least one cell that has been successfully registered / attached / camped corresponding to the first TAC, and further determines that among the at least one cell that has been successfully registered / attached / camped corresponding to the first TAC, there are other cells besides the first cell corresponding to the first network device.

[0094] In other embodiments, where the first correspondence includes a correspondence between each TAC and at least one cell that has been successfully registered / attached / camped and at least one cell that has failed to be registered / attached / camped, the terminal device can determine from the first correspondence at least one cell that has been successfully registered / attached / camped to the first TAC that the terminal device can determine, and further determine, that among the at least one cell that has been successfully registered / attached / camped to the first TAC, there are other cells besides the first cell corresponding to the first network device.

[0095] In some other embodiments, where the first correspondence includes the correspondence between each TAC and at least one cell that has failed to register / attach / stay, the terminal device can determine at least one cell that has failed to register / attach / stay corresponding to the first TAC, and then determine that among all the cells corresponding to the first TAC, the cells other than the at least one cell that has failed to register / attach / stay are at least one cell that has successfully registered / attached / stayed corresponding to the first TAC, thereby determining that among the at least one cell that has successfully registered / attached / stayed corresponding to the first TAC, there are other cells besides the first cell corresponding to the first network device.

[0096] S403, The terminal device disables the first cell.

[0097] In some embodiments, the terminal device disables the first cell corresponding to the first network device for a first period of time.

[0098] In some embodiments, the first duration may be determined by the terminal device according to a pre-configuration, or the first duration may be sent to the terminal device by a first network device or other network devices. In some embodiments, the first duration may be less than, greater than, or equal to the second duration. For example, the first duration may be 1 hour, 6 hours, 12 hours, or 24 hours.

[0099] In some embodiments, the duration for which the terminal device disables the first cell each time can always be the first duration. For example, when the terminal device disables the first cell for the first time, the duration of disabling the first cell is the first duration. After the first duration, if the terminal device sends a request to the first network device and receives a rejection message from the first network device, the terminal device can disable the first cell again, and the duration of disabling the first cell is still the first duration, and so on.

[0100] In other embodiments, the duration for which the terminal device disables the first cell each time can increase with the number of times it disables the cell. For example, when the terminal device disables the first cell for the first time, the duration is a first duration. After the first duration, if the terminal device sends a request to the first network device and receives a rejection message from the first network device, the terminal device disables the first cell again for a third duration, which is longer than the first duration. This continues until the duration for which the terminal device disables the first cell is greater than or equal to a target duration. At this point, the terminal device sets the duration for each subsequent disabling of the first cell to the target duration. When the terminal device successfully registers / attaches / camps with the first cell, it no longer disables the first cell. For example, the duration of the next disabling of the first cell can be determined by adding a preset duration to the current disabling duration, or by multiplying the current disabling duration by a preset coefficient greater than 1.

[0101] The following describes the behavior of the terminal device when it successfully registers in the first cell:

[0102] In some embodiments, if the terminal device successfully registers / attaches / camps with the first network device, and if the terminal device searches, selects, reselects, or switches to the second cell corresponding to the first TAC, and the cell information of the second cell is not recorded, the terminal device records the cell information of the second cell corresponding to the first TAC. In other embodiments, if the cell information of the second cell has already been recorded, the terminal device does not record the cell information of the second cell.

[0103] In some embodiments, the cell information of the second cell not being recorded may include: the cell information of the second cell not being stored, or the cell information of the second cell not being included in a preset list. In any embodiment of this application, the preset list may include a first correspondence.

[0104] In some embodiments, the terminal device recording the cell information of the second cell corresponding to the first TAC may include: the terminal device storing the cell information of the second cell corresponding to the first TAC, or the terminal device storing the cell information of the second cell corresponding to the first TAC in a preset list.

[0105] In some embodiments, successful registration / attachment / residence of a terminal device to the first network device may include: the terminal device sending a request to the first network device and receiving acceptance information sent by the first network device.

[0106] In some embodiments, taking signaling in a 5G standard as an example, the terminal device can send a registration request, a joint registration request, a mobility registration update request, a joint mobility registration update request, or a service request to the first network device, and receive an acceptance message from the first network device. In other embodiments, taking signaling in a 4G standard as an example, the terminal device can send an attach request, a joint attach request, a tracking area update request, a joint tracking area update request, or a service request to the first network device, and receive an acceptance message from the first network device.

[0107] In other implementations, if the terminal device successfully registers / attaches / camps with the first network device, and if the terminal device searches, selects, reselects, or switches to the third cell corresponding to the second TAC, and if the second TAC is not recorded, the terminal device records the second TAC and the cell information of the third cell corresponding to the second TAC. In other embodiments, if the cell information of the second TAC and the third cell has already been recorded, the terminal device no longer records the cell information of the second TAC and the third cell.

[0108] In some embodiments, the fact that the second TAC is not recorded may include: the second TAC is not stored, or the second TAC is not included in a preset list.

[0109] In some embodiments, the terminal device records the second TAC and the cell information of the third cell corresponding to the second TAC, which may include: the terminal device storing the second TAC and the cell information of the third cell corresponding to the second TAC, or the terminal device storing the second TAC and the cell information of the third cell corresponding to the second TAC in a preset list.

[0110] In some other embodiments, if the terminal device successfully registers / attaches / resides with the first network device, and if the terminal device searches, selects, reselects, or switches to the third cell corresponding to the second TAC, and the cell information of the third cell is not recorded even though the second TAC has been recorded, the terminal device records the cell information of the third cell corresponding to the second TAC.

[0111] In some embodiments, the cell information of the third cell is not recorded, which may include: the cell information of the third cell is not stored, or the cell information of the third cell is not included in a preset list.

[0112] In some embodiments, the terminal device recording the cell information of the third cell corresponding to the second TAC may include: the terminal device storing the cell information of the third cell corresponding to the second TAC, or the terminal device storing the cell information of the third cell corresponding to the second TAC in a preset list.

[0113] The following describes the solution implemented by the dual-SIM terminal device:

[0114] In some embodiments, the method further includes: if the terminal device receives a rejection message corresponding to the first SIM sent by the first network device, and if the second SIM of the terminal device successfully registers / attaches / camps to the second cell corresponding to the first TAC, the terminal device disables the first cell.

[0115] In any embodiment of this application, the terminal device receiving the rejection information corresponding to the first SIM sent by the first network device may include: the terminal device sending a request corresponding to the first SIM to the first network device and receiving the rejection information sent by the first network device.

[0116] In any embodiment of this application, the successful registration / attachment / camping of the second SIM of the terminal device to the second cell corresponding to the first TAC may include: the terminal device sending a request corresponding to the second SIM to the second network device corresponding to the first TAC, and successfully registering / attaching / camping to the second cell corresponding to the second network device.

[0117] In any embodiment of this application, the request corresponding to the first SIM / second SIM may include an identifier corresponding to the first SIM / second SIM. In any embodiment of this application, the identifier in the identifier corresponding to the first SIM / second SIM may include at least one of the following: IMSI, GUTI, IMEI, TMSI, P-TMSI, or user's mobile phone number.

[0118] In any embodiment of this application, the terminal device sends a request corresponding to the first SIM / second SIM to the first network device. In some embodiments, this can be described as the terminal device registering the first SIM / second SIM.

[0119] In some embodiments, if the second SIM of the terminal device successfully registers / attaches / camps to the second cell corresponding to the first TAC, then among the at least one successfully registered / attached / camped cell corresponding to the first TAC, including the second cell other than the first cell corresponding to the first network device, the terminal device disables the first cell. In some embodiments, if the second SIM of the terminal device successfully registers / attaches / camps to the second cell corresponding to the first TAC, and the second cell corresponding to the first TAC is not recorded, the second cell corresponding to the first TAC is recorded.

[0120] In this embodiment, in a dual-SIM terminal, if one SIM card receives a rejection message when registering with the first cell corresponding to the first TAC, but the other SIM card is currently successfully registered / attached / camped with the second cell corresponding to the first TAC, it indicates that at least one of the successfully registered / attached / camped cells corresponding to the first TAC includes cells other than the first cell corresponding to the first network device. In this case, the terminal device can disable only the first cell, instead of disabling the first TAC. In this embodiment, if the first cell is disabled, the terminal device can initiate a registration request, attachment request, or service request to the second cell.

[0121] In some embodiments, the method further includes: if the terminal device receives a rejection message corresponding to the first SIM sent by the first network device, and if the second SIM of the terminal device successfully registers / attaches / camps in the first cell, the terminal device resends the registration request, attachment request, or service request corresponding to the first SIM to the first network device.

[0122] In any embodiment of this application, the successful registration / attachment / camping of the second SIM of the terminal device to the first cell may include: the terminal device sending a request corresponding to the second SIM to the first network device corresponding to the first TAC, and successfully registering / attaching / camping to the first cell corresponding to the first network device.

[0123] In some embodiments, if the second SIM of the terminal device is successfully registered / attached / camped to the first cell, indicating that the first cell corresponding to the first TAC is available, the terminal device may resend the registration request, attachment request or service request corresponding to the first SIM to the first network device.

[0124] In this embodiment of the application, in a dual-SIM terminal, if one SIM card receives a rejection message when registering with the first cell corresponding to the first TAC, but the other SIM card is currently successfully registered / attached / camped in the first cell, the terminal device can resend the registration request, attachment request, or service request corresponding to the first SIM to the first network device, instead of blocking the first cell or blocking the first TAC. Furthermore, after the terminal device resends the registration request, attachment request, or service request corresponding to the first SIM to the first network device, if the camping is successful, the process is complete. If a rejection message is received again from the first network device, the terminal device can determine whether at least one cell that has been successfully registered / attached / camped in corresponding to the first TAC includes cells other than the first cell corresponding to the first network device. If yes, the terminal device disables the first cell; otherwise, the terminal device disables the first TAC.

[0125] In some embodiments, the method further includes: if the terminal device receives rejection information corresponding to the first SIM sent by the first network device, and if the second SIM of the terminal device successfully registers / attaches / camps to the third cell corresponding to the second TAC, the terminal device disables the first cell, or the terminal device disables the first TAC.

[0126] In any embodiment of this application, the successful registration / attachment / camping of the second SIM of the terminal device to the third cell corresponding to the second TAC may include: the terminal device sending a request corresponding to the second SIM to the third network device corresponding to the second TAC, and successfully registering / attaching / camping to the third cell corresponding to the third network device.

[0127] In this embodiment of the application, the terminal device disables the first cell, or the terminal device disables the first TAC, depending on whether at least one cell that has been successfully registered / attached / camped to the first TAC includes other cells besides the first cell corresponding to the first network device. If it includes other cells, the terminal device disables the first cell, and / or if it does not include other cells, the terminal device disables the first TAC.

[0128] In some embodiments, the rejection information includes the reason value #15. In other embodiments, the rejection information may also include other reason values ​​listed or not listed above, and this application does not impose any limitations on this.

[0129] Figure 5 This application provides a flowchart illustrating a method for handling successful or failed registration / attachment / residence of a terminal device, as shown in the embodiments below. Figure 5 As shown, this method is applied to a terminal device, and the method includes:

[0130] S501. Has the terminal device successfully registered / attached / resided with the first cell?

[0131] In some embodiments, the first cell may be the cell corresponding to the first TAC.

[0132] If S501 is negative, execute S502; if S501 is positive, execute S507.

[0133] S502, The terminal device receives a rejection message sent by the first network device.

[0134] In some embodiments, the first network device corresponds to the first cell. In some embodiments, the rejection information may include the reason value #15.

[0135] S503, The terminal device determines whether the first TAC is in the database.

[0136] In any embodiment of this application, the database may include the first correspondence described above. In any embodiment of this application, the database may be understood as the same as the collaborative database.

[0137] If S503 is true, execute S504; if S503 is false, execute S506.

[0138] S504. The terminal device determines whether the at least one cell that has been successfully registered / attached / camped to corresponding to the first TAC includes cells other than the first cell.

[0139] If S504 is true, execute S505; if S504 is false, execute S506.

[0140] S505: The terminal device is not allowed to execute the TAC ban, but instead disables the current first cell.

[0141] S506, no additional processing is required, the default protocol procedure is followed.

[0142] In S506, when the terminal device follows the default protocol procedure, the terminal device disables the first TAC.

[0143] In any embodiment of this application, the duration for which the terminal device disables the first TAC each time can be the same, or the duration for which the terminal device disables the first TAC each time can increase with the number of times it is disabled.

[0144] S507, The terminal device performs a cell search, selection, reselection, or handover to a new cell (corresponding to the second or third cell mentioned above).

[0145] S508: The terminal device determines whether the TAC corresponding to the new cell is already in the database.

[0146] In some embodiments, whether the TAC corresponding to the new cell is already in the database can correspond to whether the TAC corresponding to the new cell has been recorded.

[0147] If S508 is negative, execute S509; if S508 is positive, execute S510.

[0148] S509. The terminal device records the TAC corresponding to the new cell.

[0149] After S509, you can switch to S508.

[0150] S510: The terminal device determines whether the cell information of the new cell is already in the database.

[0151] In some embodiments, whether the cell information of the new cell is already in the database can correspond to whether the cell information of the new cell has been recorded.

[0152] If S510 is not enabled, S511 will be executed. If S510 is enabled, the terminal device will not perform the relevant actions until the terminal device performs the next registration or the next cell search, selection, reselection or handover occurs.

[0153] S511, The terminal device records the cell information of the new cell.

[0154] In this embodiment of the application, after the terminal device successfully camps on a cell, the terminal device will start recording the cell information of the camped cell and maintain the cell collaboration database (including the first correspondence mentioned above). Whenever a cell change occurs, such as cell search, selection, reselection, or handover, the cell information will be updated. When camping on a new TAC, the new TAC will be saved to the database. If a new cell is found under the new TAC, the new cell will be updated to the corresponding new TAC.

[0155] Table 1 schematically illustrates the contents of this database for cell coordination:

[0156] Table 1

[0157]

[0158] In this embodiment of the application, if the terminal device fails to register / attach / reside and receives a rejection code of #15 from the network device, the terminal device can query whether the current TAC exists in the database. If it does, it can check whether there are other cells that can be successfully registered under the TAC. If so, it is not allowed to disable the TAC, but the cell is disabled instead.

[0159] The embodiments of this application can reduce the impact of network #15 rejection code and avoid the situation where disabling the current TAC would cause all cells under the current TAC to become unusable, resulting in no cells available for the current standard. Thus, this application can improve network stability.

[0160] In this embodiment of the application, a cell collaboration database is constructed by collecting cell information to correct temporary network problems, thereby improving network stability.

[0161] In this embodiment, the source of the cell collaboration database is not limited to the current SIM card. For dual-SIM terminals, a database can be maintained jointly, and different strategies can be adjusted for SIM card combinations from the same operator.

[0162] For example, a terminal device has two SIM cards that belong to the same operator. The registration information of these two SIM cards can be referenced from each other. For example, if SIM1 encounters a network #15 rejection code, while the other card SIM2 does not, then there are three situations as shown in Table 2. The following three situations are mainly classified by whether the TAC of the cell where the two SIM cards are registered is the same and whether different strategies are adopted.

[0163] Table 2 shows the policy corresponding to SIM1 when SIM1 receives the #15 rejection code and SIM2 successfully stays on the SIM card.

[0164] Table 2
