Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, but is not limited thereto, and in particular, relates to a network access control method, apparatus, terminal, and storage medium. Background Art

[0002] In related technologies for the mobile network access of a multi-SIM terminal, when the primary SIM card fails to camp on the network, the primary SIM card will retry camping on the network, but the secondary SIM card will not start camping on the network until its service priority is relatively high. For example, after hot-plugging the terminal, the primary SIM card network is often preferentially registered, and the service priority of the primary SIM card is relatively high, resulting in the Radio Frequency (RF) resources being continuously occupied by the primary SIM card.

[0003] After the default data card (DDS) of the terminal is switched, the primary SIM card and the secondary SIM card are swapped. Before the swap, the primary SIM card still occupies the RF resources and still needs to receive the authentication feedback information after the camping-on failure. For example, when completing the re-synchronization operation and retrying network access, it will be detected that the primary SIM card has changed. Only then will the swapped primary SIM card start to occupy the RF resources and perform network registration. Therefore, when the user uses the terminal network function, the camping-on speed is often slow, affecting the user experience. Summary of the Invention

In this way, after the target SIM card fails to camp on the network, the identity of the default data card is detected immediately. If the default data card changes from the target SIM card to another SIM card, under the specified type of failure cause, there is no need to perform re-authentication operations such as re-synchronization, nor to wait for the authentication feedback information to detect the change of the DDS, so as to timely switch the RF resources occupied by the target SIM card to the changed default data card, and reduce the time for the non-default data card to occupy the RF resources for too long, resulting in the default data card being unable to camp on the network for a long time. Therefore, it reduces the time for the main card, that is, the default data card, to camp on the network for too long due to the main and secondary card switching, and improves the network access efficiency.

[0078] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0079] For the convenience of those skilled in the art to understand, multiple implementation manners are enumerated in the embodiments of the present disclosure to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided by the embodiments of the present disclosure can be executed alone, or can be executed together after being combined with the methods of other embodiments in the embodiments of the present disclosure, or can be executed alone or in combination with some methods in other related arts; the embodiments of the present disclosure do not make any limitations in this regard.

[0080] As shown Figure 1 in the figure, in this embodiment, a network access control method is provided and executed by a terminal, including:

[0081] S110: After generating failure information of a mobile network authentication request based on a target user identification SIM card, determining a failure cause type based on the failure information;

[0082] S120: If the failure cause type is a preset type, determining whether the current default data card (DDS) is the target SIM card;

[0083] S130: If the current DDS is not the target SIM card, allocating radio frequency (RF) resources occupied by the target SIM card to the current DDS;

[0084] S140: Accessing a mobile network corresponding to the current DDS based on the RF resources.

[0085] In an embodiment of the present disclosure, the terminal may be a terminal device configured with at least two subscriber identity module (SIM) cards, such as a mobile phone, a tablet computer, or a smart watch with an independent call function, etc. For example, it may include a first SIM card and a second SIM card. Among them, when the first SIM card receives a mobile network authentication request, the first SIM card may be the default data card (DDS) in the terminal, that is, the primary SIM card in the terminal. The terminal may also include a second SIM card. For example, when the first SIM card is the primary SIM card, the second SIM card may be used as a secondary SIM card.

[0086] Here, the primary SIM card, that is, the DDS, may be the SIM card that the terminal uses by default or preferentially for calls, mobile network access, and usage, etc. The secondary SIM card may be used as an alternative SIM card. For example, it can be used for the user to switch the secondary SIM card to the primary SIM card on the terminal.

[0087] In one embodiment, in step S110, the target SIM card may be the current default data card (DDS) to be resident. For example, the target SIM card may be the first SIM card or the second SIM card in the terminal. The mobile network authentication request may be an authentication request (Authentication request) sent by the mobile network when the target SIM card needs to be resident, such as for authenticating the identity information of the terminal.

[0088] In related technologies, as Figure 2As shown, after a hot plug operation on the terminal, the primary SIM card can be the target SIM card. For example, if it is the first SIM card in the terminal, then at this time the target SIM card preferentially accesses the mobile network, that is, a mobile network access request (Attach request) is sent based on the target SIM card and an authentication request returned by the network side in response to the mobile network access request is received. And a DDS switch occurs on the terminal application processor (Application Process, AP) side, that is, at this time, DDS switches from the first SIM card to the second SIM card.

[0089] In the related art, when determining that the cause value carried in the failure information returned to the network side in response to an authentication failure is "Synch failure", re-authentication, that is, retry Authentication, is performed, or the T3320 timer is started, and re-synchronization (Synch) is performed during the timing. During the re-synchronization process, it is required that the Smart Grid Communication Network (SGCN) delete all unused authentication vectors of the International Mobile Subscriber Identifier (IMSI) in it and obtain new vectors from the Home Location Register (HLR). When the re-synchronization is completed, the network side will start the verification and encryption program. After receiving the authentication and encryption request message, if it is running, the terminal will stop the timer T3320. After receiving the authentication request feedback information (Authentication response), the network access (Attach) is retried. At this time, the terminal only detects that the target SIM card is no longer the primary card, and at this time, the RF resources of the target SIM card are switched to the second SIM card, that is, the current DDS is used for network registration.

[0090] In one embodiment, before step S110, the method may further include: after detecting a hot plug operation of the terminal, determining the default data card in the terminal as the target SIM card; sending a mobile network access request based on the target SIM card; receiving a mobile network authentication request corresponding to the mobile network access request. For example, after the terminal performs operations such as SIM card insertion or SIM card switching, the target SIM card that is currently the primary card is determined, and a mobile network access request (Attach request) is sent based on the target SIM card, and an authentication request returned by the network side based on the mobile network access request is received.

[0091] In one embodiment, the generated failure information may be the failure information (Authentication_failure) generated by the terminal and returned to the network side after the authentication fails based on the authentication request. Among them, the failure reason type may be indicated in the failure information. For example, the failure reason type identifier may be carried. Exemplarily, the failure reason value or the failure reason type code, etc. may be carried in the failure information. After the failure information is generated, determining the failure reason type based on the failure information may be to determine the failure reason type indicated by the failure information by obtaining the carried failure reason type identifier, etc.

[0092] In one embodiment, the current DDS is also a SIM card in the terminal. For example, the current DDS is the first SIM card or the second SIM card. Determining whether the current DDS is the target SIM card may be to detect whether a DDS switching operation occurs in the terminal, or to detect whether the card identifier of the current DDS is consistent with the card identifier of the target SIM card, etc. For example, the current DDS is not the target SIM card, but has been switched from the first SIM card corresponding to the target SIM card to the second SIM card.

[0093] Among them, the mobile network modes supported by the first SIM card and the second SIM card may be the same or different. For example, the mobile network mode supported by the second SIM card is higher than that of the first SIM card, so that when the DDS is switched to the second SIM card, a mobile network with better signal quality can be quickly accessed.

[0094] Exemplarily, the first SIM card may support a 2G or 3G mobile network, and the second SIM card may support a 5G Stand Alone (SA) mobile network.

[0095] In one embodiment, when it is detected that the current DDS has been switched, the radio frequency (RF) resources occupied by the target SIM card with network registration failure are switched to the current DDS. For example, when the target SIM card is the first SIM card, the RF resources it occupies are switched to the second SIM card that is currently the primary SIM card.

[0096] In one embodiment, allocating the RF resources occupied by the target SIM card to the current DDS may be to obtain the first total amount of the RF resources occupied by the target SIM card and the second total amount of the RF resources occupied by the current DDS; and allocate the RF resources occupied by the target SIM card to the current DDS according to the difference between the first total amount and the second total amount.

[0097] For example, when the difference between the total amount of the first resource and the total amount of the second resource reaches a preset value, allocate the RF resources occupied by the target SIM card to the current DDS, or allocate the RF resources occupied by the target SIM card to the current DDS according to a preset ratio of the difference between the total amount of the first resource and the total amount of the second resource. The preset ratio can be a ratio determined according to the historical DDS resource occupancy in the terminal and / or the resource amount required by the current DDS.

[0098] In one embodiment, allocating the radio frequency (RF) resources occupied by the target SIM card to the current DDS can be to allocate the RF resources occupied by the target SIM card to the current DDS according to the amount of RF resources required for the current DDS to access the corresponding mobile network.

[0099] In one embodiment, allocating the radio frequency (RF) resources occupied by the target SIM card to the current DDS can be to determine to allocate the RF resources occupied by the target SIM card to the current DDS according to the mobile network mode or type corresponding to the current DDS. For example, for different mobile network types corresponding to the current DDS, different proportions of RF resources are retrieved from the RF resources occupied by the target SIM card and allocated to the current DDS, etc.

[0100] In this way, after the target SIM card fails to register on the network, detect whether the DDS is different from that before registration. If the DDS changes, the RF resources occupied by the target SIM card can be switched to the current DDS in a timely manner, thereby reducing the time that the non-default data card occupies the RF resources for too long, resulting in the default data card being unable to register on the network for a long time. Therefore, the waiting time for the main card, i.e., the default data card, to quickly obtain RF resources after the main and secondary card switching, which leads to too long network access waiting time, is reduced, and thus the network access efficiency is improved.

[0101] It should be noted that those skilled in the art can understand that the method provided by the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0102] In some embodiments, as Figure 3 shown, S120 may include:

[0103] S121: If the failure reason type indicates that the serial number verification received by the terminal based on the authentication request fails, determine whether the current default data card (DDS) is the target SIM card.

[0104] In the embodiments of the present disclosure, the sequence number received based on the authentication request may be the sequence number (Sequence Number, SQN) carried in the received authentication request. For example, the received authentication request may include an authentication token (AuthenticationToken, AUTN), and the SQN to be verified is recorded in the AUTN, etc.

[0105] In one embodiment, when the terminal fails to verify the sequence number SQN, it indicates that the card identifier of the SIM card currently used by the terminal for verification does not match the SQN indicated in the authentication request. At this time, it can be determined whether the verification fails due to a change in the card identifier of the default data card caused by DDS switching.

[0106] In one embodiment, the failure reason type indicates that the terminal fails to verify the sequence number received based on the authentication request. The reason value corresponding to the failure reason type may be "Synch failure", indicating that the SQN in the authentication request sent by the network side fails to synchronize with the terminal.

[0107] In one embodiment, determining whether the current DDS is the target SIM card may be determining whether the card identifier of the current DDS is the same as the card identifier of the target SIM card. Among them, the card identifier of the target SIM card can be determined according to the received sequence number. For example, the sequence number SQN indicated in the authentication request sent by the network side is the SQN corresponding to the primary SIM card in the terminal before DDS switching, that is, the target SIM card.

[0108] In this way, when the verification of the sequence number based on the authentication request fails, it is more likely that the DDS switching in the terminal causes the change of the primary SIM card. Therefore, determining whether the DDS is still the same as the target SIM card can more quickly and accurately detect the occurrence of the DDS switching operation.

[0109] It should be noted that those skilled in the art can understand that the method provided by the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0110] In some embodiments, the allocating the radio frequency (RF) resources occupied by the target SIM card to the current DDS includes:

[0111] Determining whether the current DDS is connected to the corresponding mobile network;

[0112] If the current DDS is not connected to the corresponding mobile network, determining whether the RF resources required for the current DDS to connect to the corresponding mobile network are occupied by the target SIM card;

[0113] If the RF resources are occupied by the target SIM card, allocate the RF resources occupied by the target SIM card to the current DDS.

[0114] In an embodiment of the present disclosure, determining whether the current DDS is connected to the corresponding mobile network may be determining whether the mobile network authentication success information corresponding to the current DDS is detected within a preset duration, or determining whether data interaction occurs between the current DDS and the corresponding mobile network within a preset duration, etc.

[0115] In one embodiment, determining whether the radio frequency (RF) resources required for the current DDS to access the corresponding mobile network are occupied by the target SIM card may be determining whether the required RF resources are occupied by the target SIM card according to the RF resource identifier and / or the total amount of RF resources required for the current DDS to access the corresponding mobile network.

[0116] Among them, the RF resource identifier required for the current DDS to access the corresponding mobile network can be determined, and then it can be determined whether the RF resources corresponding to the RF resource identifier are being occupied by the target SIM card. For example, it is determined whether the RF resource identifier occupied by the target SIM card contains the RF resource identifier required by the current DDS. If so, it can be determined that the required RF resources are occupied by the target SIM card.

[0117] Among them, the total amount of RF resources required for the current DDS to access the corresponding mobile network can also be determined, and then it is determined whether the remaining available RF resource amount in the terminal is greater than the total amount of the RF resources. If the remaining RF resource amount is less than or equal to the total amount of the RF resources, it can be determined that the required RF resources are occupied by the target SIM card.

[0118] In one embodiment, allocating the RF resources occupied by the target SIM card to the current DDS may be allocating the RF resources occupied by the target SIM card to the current DDS according to the RF resource identifier and / or the total amount of RF resources occupied by the target SIM card, and the RF resource identifier and / or the total amount of RF resources required for the current DDS to access the corresponding mobile network.

[0119] In one embodiment, allocating the RF resources occupied by the target SIM card to the current DDS may be allocating some or all of the RF resources occupied by the target SIM card to the current DDS according to the total amount of RF resources occupied by the target SIM card and the total amount of RF resources required for the current DDS to access the corresponding mobile network.

[0120] For example, when the total amount of RF resources required for the current DDS to access the corresponding mobile network is less than or equal to the total amount of RF resources occupied by the target SIM card, the total amount of RF resources required for the current DDS to access the corresponding mobile network can be retrieved from the RF resources occupied by the target SIM card and allocated to the current DDS.

[0121] Alternatively, when the total amount of RF resources required for the current DDS to access the corresponding mobile network is greater than the total amount of RF resources occupied by the target SIM card, all the RF resources occupied by the target SIM card can be allocated to the current DDS, or the total amount of RF resources occupied by the target SIM card minus the amount of RF resources that the target SIM card needs to reserve can be allocated to the current DDS.

[0122] In this way, when it is determined that the current DDS needs to access the mobile network and the required RF resources are still occupied by the target SIM card, the RF resources occupied by the target SIM card are released and allocated to the current DDS, thereby reducing the switching of the RF resources of the target SIM card when the RF resources of the target SIM card have been released, and further improving the accuracy and efficiency of RF resource scheduling.

[0123] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0124] In some embodiments, the allocating the RF resources occupied by the target SIM card to the current DDS includes:

[0125] Determining whether the mobile network supported by the current DDS is a preset network;

[0126] If the mobile network supported by the current DDS is a preset network, then allocate the RF resources occupied by the target SIM card to the current DDS.

[0127] In the embodiments of the present disclosure, the preset network can be a network type that needs to be accessed or preferentially accessed. For example, when the mobile network supported by the current DDS is the preset network 5G SA network, allocate the RF resources occupied by the target SIM card to the current DDS, etc.

[0128] In one embodiment, the preset network can be determined according to the historical mobile network usage of the terminal. For example, it is determined according to the mobile network with the highest historical usage frequency or usage duration of the terminal.

[0129] In one embodiment, the preset network can also be determined according to the mobile network types supported by multiple SIM cards in the terminal. For example, the preset network can be the mobile network with the highest network mode among the mobile networks supported by multiple SIM cards in the terminal, etc.

[0130] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0131] In some embodiments, allocating the radio frequency (RF) resources occupied by the target SIM card to the current DDS includes:

[0132] Obtaining a first service priority of the target SIM card;

[0133] Setting a second service priority of the current DDS based on the first service priority; the second service priority is higher than the first service priority;

[0134] Allocating the RF resources occupied by the target SIM card to the current DDS based on the second service priority.

[0135] In the embodiments of the present disclosure, the service priority may be the network access (Attach) service priority of the SIM card, or the overall service priority of the SIM card, etc. Among them, the higher the service priority, the higher the priority of the corresponding SIM card to occupy RF resources. When multiple SIM cards need RF resources at the same time, the SIM card with a higher service priority preferentially occupies the RF resources.

[0136] In one embodiment, obtaining the first service priority of the target SIM card may be obtaining the network access service priority of the mobile network corresponding to the target SIM card in the terminal. Among them, the network access service priority is determined by the mobile network type or the priority order recorded by the terminal.

[0137] In one embodiment, setting the second service priority of the current DDS based on the first service priority may be setting the second service priority of the mobile network corresponding to the current DDS based on the first service priority. For example, it may be setting or modifying the second service priority of the mobile network corresponding to the current DDS based on the first service priority.

[0138] Exemplarily, if the first service priority is level 1, the second service priority may be set to level 2 or level 3, etc., so as to satisfy that the network access service priority of the current DDS is higher, and it can preferentially occupy RF resources to ensure the stability of the network access service.

[0139] In one embodiment, allocating the RF resources occupied by the target SIM card to the current DDS based on the second service priority may be allocating the RF resources occupied by the target SIM card to the current DDS based on the second service priority and the first service priority. For example, determining the total amount of RF resources required to allocate the RF resources occupied by the target SIM card to the current DDS based on the difference between the second service priorities.

[0140] Exemplarily, the proportion of RF resources allocated to the current DDS among the RF resources occupied by the target SIM card may be positively correlated with the gap between the second service priority and the first service priority. For example, if the second service priority is higher than the first service priority and the gap between the second service priority and the first service priority is larger, a higher proportion of RF resources can be retrieved from the RF resources occupied by the target SIM card and allocated to the current DDS.

[0141] In this way, by setting the service priority corresponding to the current DDS, RF resources can be more stably scheduled for the current DDS, thereby improving the stability of the current DDS during the process of accessing the mobile network and reducing the slow network registration speed and high volatility caused by the preemption of RF resources by other SIM cards.

[0142] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0143] In some embodiments, the method further includes:

[0144] After the current DDS accesses the corresponding mobile network based on the RF resources, allocate the RF resources occupied by the current DDS to the target SIM card;

[0145] Access the mobile network corresponding to the target SIM card through the RF resources.

[0146] In the embodiments of the present disclosure, since the target SIM card switches the RF resources to the current DDS after the network registration fails, after the current DDS successfully registers on the network, the RF resources can be switched back to the target SIM card to complete the network registration of the target SIM card.

[0147] In one embodiment, allocating the RF resources occupied by the current DDS to the target SIM card can be when the service processing situation of the current DDS and the RF resources occupied by the current DDS meet preset conditions. For example, the preset conditions can be that the service processing volume or resource occupancy rate of the current DDS is lower than a preset threshold, or it can also be that the total amount of RF resources occupied by the current DDS is higher than a preset threshold value of the resources required for the service processing of the current DDS, etc.

[0148] In one embodiment, after accessing the mobile network corresponding to the target SIM card through the RF resources, it may further include: when the service priority of the current target SIM card is lower than the service priority of the current DDS, or when the current DDS remains unchanged, switch the RF resources occupied by the target SIM card back to the current DDS.

[0149] Thus, after the current DDS successfully registers and accesses the mobile network, the RF resources can be switched back to the target SIM card that has not successfully camped on the network to re-camp on the network, so that the RF resource scheduling can be more flexibly achieved, and the camping operation efficiency of multiple SIM cards in the terminal can be further improved.

[0150] It should be noted that those skilled in the art can understand that the method provided by the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0151] In some embodiments, as Figure 4 shown, S110 may include:

[0152] S111: After generating the failure information of the mobile network authentication request based on the target user identification SIM card, determine the failure cause type based on the cause value carried in the failure information.

[0153] In the embodiments of the present disclosure, the cause value may be a preset value indicating the failure cause type. For example, it may be a numerical value in binary, octal, or hexadecimal, etc., or a preset type identification value, etc. For example, the cause value indicating the SQN verification failure may be "Synch failure", and the cause value indicating the local area network address (Media Access Control Address, MAC) error may be "MAC failure", etc.

[0154] In one embodiment, determining the failure cause type based on the cause value carried in the failure information may be to determine the cause value carried in the failure information according to the SQN carried in the authentication request, and determine the failure cause type according to the cause value. For example, determine the cause value carried in the failure information according to whether the SQN matches the card identification corresponding to the current DDS, etc.

[0155] Among them, the SQN carried in the authentication request may be the SQN recorded in the AUTN parameter carried in the authentication request, etc.

[0156] It should be noted that those skilled in the art can understand that the method provided by the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0157] In some embodiments, as Figure 5 shown, the method further includes:

[0158] S150: If the failure cause type is not the preset type, re-receive the mobile network authentication request of the target SIM card.

[0159] In the embodiments of the present disclosure, if the failure reason type is not the preset type, for example, the reason value is not "Synchfailure", it indicates that the current default data card of the terminal is not inconsistent with the SQN carried in the authentication request. Therefore, at this time, DDS changes often do not occur, and instead of detecting whether DDS has changed, the terminal directly continues the network registration attempt for the target SIM card.

[0160] In one embodiment, if the re - received authentication request still fails in authentication, continue to determine the failure reason type indicated by the failure information. If the failure reason type is the preset type, determine whether the current default data card DDS is the target SIM card; if the current DDS is not the target SIM card, allocate the radio frequency RF resources occupied by the target SIM card to the current DDS; access the mobile network corresponding to the current DDS based on the RF resources.

[0161] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0162] In some embodiments, the method further includes:

[0163] If the authentication request based on the mobile network of the target SIM card successfully accesses the mobile network corresponding to the target SIM card, determine whether the current DDS is the target SIM card;

[0164] If the current DDS is not the target SIM card, allocate the RF resources occupied by the target SIM card to the current DDS.

[0165] In the embodiments of the present disclosure, if the target SIM card successfully registers on the network, the RF resources occupied by the target SIM card can be directly allocated to another SIM card, such as the second SIM card, or the RF resources of the target SIM card can be allocated to the current DDS after determining that the current DDS is not the target SIM card.

[0166] In one embodiment, if the current DDS is not the target SIM card, allocating the RF resources occupied by the target SIM card to the current DDS may include: if the current DDS is not the target SIM card, and the mobile network corresponding to the current DDS is the preset network, or the mobile network mode corresponding to the current DDS is higher than that of the target SIM card, then allocate the RF resources occupied by the target SIM card to the current DDS.

[0167] In this way, the flexibility and intelligence of RF resource scheduling can be further improved, thereby enhancing the network registration speed of multi - SIM cards and the user experience.

[0168] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0169] To better understand the embodiments of the present disclosure, the technical solution of the present disclosure will be further described below through an exemplary embodiment:

[0170] In this embodiment, a network access control method in a multi-SIM card terminal is provided. Taking the terminal as a mobile phone as an example, it may specifically include: Figure 6 As shown, taking the terminal as a mobile phone as an example, it may specifically include:

[0171] 1. Check whether the network mode of the mobile phone terminal is that the main card supports 2 / 3G and the secondary card supports 5G SA network (for example, the card supporting the 2 / 3G network mode is the first SIM card, and the card supporting the 5G SA network mode is the second SIM card);

[0172] 2. Perform a hot plug operation;

[0173] 3. Perform an Attach request (the first SIM card of the main card occupies the RF resource);

[0174] 4. Check whether the Authentication authentication is successful. If successful, the first SIM card of the main card camps on the network. If failed, go to step 6;

[0175] 5: At this time, a DDS switch occurs on the AP side (the main card becomes the second SIM card, the secondary card becomes the first SIM card, and at this time, the first SIM card of the secondary card occupies the RF resource);

[0176] 6. Determine whether the cause value carried in the failure message Authentication_failure is Synch failure. If not, re-attempt authentication. If so, go to step 7;

[0177] 7. Check whether the main card, the second SIM card, supports 5G SA network and whether the RF resource is occupied by the first SIM card of the secondary card. If so, go to step 8. If not, go to step 9;

[0178] 8. Increase the priority of the 5G SA network registration service so that the second SIM card of the main card occupies the RF resource;

[0179] 9. Perform 5G SA network registration and end;

[0180] 10. Subsequently, re-attempt to attach the network access of the first SIM card of the secondary card and perform 2 / 3G network registration.

[0181] Thus, considering that the 5G SA network will bring a better user experience, it is preferred to register for the 5G SA network first. After successfully registering for the 5G SA network, the process of re-registering for the 2 / 3G network can be carried out.
