[0045] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0049] Figure 1 This is a schematic flowchart of a method for sending an indication according to an embodiment of the present disclosure. The method for sending an indication shown in this embodiment can be applied to a first base station, which can communicate with a core network or a terminal serving as a user equipment, and the core network can communicate with the first base station and a second base station other than the first base station.

[0050] The terminals include, but are not limited to, mobile phones, tablet computers, wearable devices, sensors, unmanned aerial vehicles, IoT devices, and other communication devices. The first and second base stations include, but are not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The core network includes, but is not limited to, the core network in communication systems such as 4G base stations, 5G base stations, and 6G base stations.

[0051] like Figure 1 As shown, the method for sending an indication may include the following steps:

[0052] In step S101, in response to receiving a multiple-SIM card problem of a terminal and determining to switch the terminal to a second base station, first information is sent to a core network;

[0053] The first information carries relevant information about the multi-card problem, and the first information is used to instruct the core network to send the relevant information about the multi-card problem to the second base station.

[0054] In one embodiment, the terminal may currently access the first base station, for example, reside in a cell corresponding to the first base station (for example, in an idle state or an inactive state), or establish a connection with the first base station (for example, in a connected state).

[0055] When a terminal determines that a multi-card problem exists (currently exists or is predicted to occur), it can send the multi-card problem information to the base station. After receiving the multi-card problem information from the terminal, the base station can further determine the target base station to which the terminal should switch when performing a cell handover (e.g., cell reselection). In this embodiment, this is referred to as the second base station.

[0056] After determining the second base station, the first base station can carry the relevant information of the multi-card problem in the first information and send it to the core network to instruct the core network to send the relevant information of the multi-card problem to the second base station, thereby solving the multi-card problem for the terminal.

[0057] For example, the second base station can wait until the terminal switches to the second base station before solving the multi-card problem for the terminal; the second base station can also send the configuration for solving the multi-card problem to the core network, and then the core network forwards it to the first base station, so that the first base station can solve the multi-card problem for the terminal according to the configuration for solving the multi-card problem provided by the second base station.

[0058] According to an embodiment of the present disclosure, the first base station can send the multi-card problem of the terminal to the second base station to which the terminal needs to switch through the core network during the process of the terminal switching cells, so that the second base station can solve the multi-card problem for the terminal.

[0059] In one embodiment, the first base station may determine whether there is an available inter-base station interface, such as an X2 interface or an Xn interface, between the first base station and the second base station.

[0060] In response to determining that an available inter-base station interface exists between the first base station and the second base station, the first base station may choose to directly send information related to the multiple card problem to the second base station through the inter-base station interface, or continue to perform the above step S101.

[0061] In response to determining that there is no available inter-base station interface between the first base station and the second base station, the first base station may perform step S101. The absence of an available inter-base station interface includes two situations: one is that there is no inter-base station interface between the first base station and the second base station; the other is that an inter-base station interface exists between the first base station and the second base station, but the interface is currently unavailable.

[0062] In one embodiment, the first base station may determine whether there is an available inter-base station interface of a specified type between the first base station and the second base station.

[0063] In response to determining that an available inter-base station interface of a specified type exists between the first base station and the second base station, the first base station may choose to directly send information related to the multiple card problem to the second base station through the inter-base station interface, or continue to perform step S101.

[0064] In response to determining that there is no available inter-base station interface of the specified type between the first base station and the second base station, the first base station may perform the above step S101.

[0065] In one embodiment, when the first base station is a primary base station in dual connectivity, the type of the second base station may be determined. The following mainly describes this embodiment in an example where the first base station is a 4G base station.

[0066] If the second base station is a 4G base station, when there is an X2 interface between the first base station and the second base station, you can choose to directly send the multi-card problem to the second base station, or execute the above step S101; when there is no X2 interface between the first base station and the second base station, you can execute the above step S101.

[0067] If the second base station is a 5G base station and the second base station is not a secondary base station of the first base station, when there is an Xn interface between the first base station and the second base station, you can choose to directly send the multi-card problem to the second base station, or execute the above step S101; when there is no Xn interface between the first base station and the second base station, you can execute the above step S101.

[0068] If the second base station is a 5G base station and the second base station is a secondary base station of the first base station, in this case, even if the first base station is a 4G base station, the first base station and the second base station can coordinate resources through the X2 interface. Therefore, when there is an X2 interface between the first base station and the second base station, you can choose to send the multi-card problem directly to the second base station (for example, carry the multi-card problem through the signaling used for resource coordination between the first base station and the second base station), or execute the above step S101; when there is no X2 interface between the first base station and the second base station, you can execute the above step S101.

[0069] In one embodiment, a plurality of SIM cards may be provided in the terminal, and the plurality of SIM cards include at least a first SIM card and a second SIM card. The multi-card problem of the terminal may be that the communication operation of the first SIM card conflicts with the communication operation of the second SIM card, for example, the communication operation performed by the first SIM card with the first base station conflicts with the communication operation performed by the second SIM card with the second base station.

[0070] The conflict between the communication operation of the first SIM card and the communication operation of the second SIM card includes but is not limited to the following situations. For example, the terminal uses the first SIM card to perform communication operations in a first system (for example, the system where the first base station is located) and uses the second SIM card to perform communication operations in a second system (a system where a base station other than the first base station is located):

[0071] When the terminal is communicating with the first system, it needs to detect the second system from time to time, such as monitoring paging, performing measurements, reading system messages, etc. This may affect the performance of the first system.

[0072] The paging timing is calculated based on the user equipment identifier (UEI). Multi-SIM terminals have multiple SIM cards, each with a corresponding UEI. However, the algorithms used to calculate the paging timing vary, which may lead to overlap in the paging timings calculated for multiple SIM cards, causing systemic paging collisions.

[0073] When the terminal receives a paging message on the second system, it needs to decide whether to respond to the paging message, and this is done based on the rules configured by the user equipment itself.

[0074] When a multi-SIM terminal decides to respond to a paging message from the second system, it must stop its current communication operations on the first system. Without a mechanism to suspend current activity, the user device will automatically disconnect from the first system (e.g., wireless resource control connection) and leave. Furthermore, after the user device leaves, the first system will continue to page it, resulting in a waste of paging resources.

[0075] When the terminal reads paging or measures in the second system, it will cause a short interval of about 20ms in the first system, which is similar to experiencing shadow fading for the first system. However, since it occurs once in each paging cycle, this may affect the network's power control and link adaptation algorithms, thereby causing waste of resources in the first system.

[0076] When the terminal decides to switch to a cell in the second system, it needs to read system information in the second system. This will cause a long gap of about one second in the first system, which the first system will interpret as an error. It is currently unclear how the UE and network handle this situation.

[0077] When the terminal performs tracking area update in the second system, it will cause a longer interval of several seconds in the first system, thus causing a greater impact on the first system.

[0078] The above-mentioned specific situations can be summarized into the following two situations:

[0079] The paging collision between the first SIM card and the second SIM card;

[0080] When using the first SIM card for communication, it is necessary to switch to using the second SIM card for communication.

[0081] In one embodiment, when using the first SIM card for communication, it is necessary to switch to using the second SIM card for communication, which may include but is not limited to the following:

[0082] The communication operation of the first SIM card conflicts with the monitoring of paging messages by the second SIM card;

[0083] The communication operation of the first SIM card conflicts with the response of the second SIM card to the paging message;

[0084] The communication operation of the first SIM card conflicts with the measurement signal of the second SIM card;

[0085] The communication operation of the first SIM card conflicts with the system information received by the second SIM card;

[0086] The communication operation of the first SIM card conflicts with the tracking area update of the second SIM card.

[0087] In one embodiment, the information related to the multi-card problem includes at least one of the following:

[0088] The multi-card problem;

[0089] Recommended configuration to resolve the described multiple card issue.

[0090] The relevant information about the multi-card problem carried by the first base station in the first information sent to the core network may include the multi-card problem itself, such as one or more of the above-mentioned types of multi-card problems; it may also include the recommended configuration of the multi-card problem determined by the first base station based on its own implementation. For example, when the first base station solved the multi-card problem for the terminal in the past, it can determine the historical configuration that successfully solved the multi-card problem for the terminal (which can be determined by the first base station itself or from other base stations), and then use the historical configuration as the recommended configuration.

[0091] Figure 2 FIG. 1 is a schematic flow chart of another method for sending an indication according to an embodiment of the present disclosure. Figure 2 As shown, in some embodiments, the method further includes:

[0092] In step S201, a measurement report sent by the terminal is received, wherein the measurement report carries the multi-card problem.

[0093] In one embodiment, when the terminal needs to switch cells, it can measure the current cell and the neighboring cells, generate a measurement report based on the measurement results, and then send the measurement report to the first base station. After receiving the measurement report, the first base station can determine the second base station to which the terminal needs to switch based on the measurement report.

[0094] The terminal can carry the multi-SIM problem in a measurement report and send it to the first base station, thereby eliminating the need to carry the multi-SIM problem report in a separate message, which is beneficial to solving the communication resource problem.

[0095] In one embodiment, the multi-card problem may occur before the terminal needs to switch cells, and is not reported to the first base station until the terminal needs to switch cells (the triggering reason is not the multi-card problem).

[0096] In one embodiment, the multi-card problem can trigger the terminal to switch cells. For example, after the terminal has a multi-card problem, if it determines that the current first base station cannot solve the multi-card problem, it can trigger the cell switching so as to access other base stations, and let other base stations solve the multi-card problem.

[0097] In one embodiment, the measurement report further carries at least one of the following:

[0098] Measurement results of the ability of multiple base stations to resolve multiple card issues;

[0099] Monitoring results of the signal quality of multiple base stations.

[0100] In addition to carrying the multi-card problem, the measurement report can also carry the measurement results of the signal quality of multiple base stations (corresponding cells); and when the base station can broadcast its own ability to solve the multi-card problem, the terminal can also monitor the base station's ability to solve the multi-card problem, and report the monitoring results to the first base station in the measurement report, so that the first base station can determine which base stations have the ability to solve the multi-card problem reported by the terminal.

[0101] Figure 3 FIG. 1 is a schematic flow chart of another method for sending an instruction according to an embodiment of the present disclosure. Figure 3 As shown, in some embodiments, the method further includes:

[0102] In step S301, the second base station is determined from the multiple base stations according to capabilities of the multiple base stations in resolving the multi-card problem and / or signal qualities of the multiple base stations.

[0103] In one embodiment, the first base station may determine the second base station from the multiple base stations based only on the signal qualities of the multiple base stations in the measurement report. For example, the first base station may select the base station with the best signal quality as the second base station.

[0104] In one embodiment, the first base station may determine the second base station from multiple base stations based solely on the capability of measuring the multi-card problems of multiple base stations in the measurement report. For example, the first base station may select a base station that can solve all multi-card problems reported by the terminal as the second base station.

[0105] In an embodiment, the first base station may further comprehensively consider the capabilities of the multiple base stations in the measurement report to solve the multi-card problem and the signal quality to determine the second base station from the multiple base stations.

[0106] For example, a candidate base station having a signal quality greater than a quality threshold may be determined from multiple base stations, and then a base station that can solve all multi-card problems reported by the terminal may be determined from the candidate base stations as the second base station.

[0107] For example, a candidate base station that can solve all multi-card problems reported by the terminal can be determined from multiple base stations, and then a base station with the best signal quality can be determined from the candidate base stations as the second base station.

[0108] If no alternative base station among multiple base stations can resolve all multi-card issues reported by the terminal, a target base station can be identified that can resolve a specific multi-card issue among the multi-card issues reported by the terminal. This specific multi-card issue can refer to a multi-card issue not affected by signal quality. In this case, the base station with the best signal quality among the target base stations can be identified as the second base station. Based on this, although the target base station cannot resolve all multi-card issues, it can resolve multi-card issues not affected by signal quality. Since the selected second base station has the best signal quality among the target base stations, the multi-card issue affected by signal quality can be alleviated to a certain extent after accessing the selected second base station.

[0109] Figure 4 FIG. 1 is a schematic flow chart of another method for sending an instruction according to an embodiment of the present disclosure. Figure 4 As shown, in some embodiments, the measurement report includes indication information for indicating that the second base station can solve the multi-card problem, and the method further includes:

[0110] In step S401, the second base station is determined according to the indication information.

[0111] In one embodiment, the terminal can autonomously determine the second base station. For example, it can determine a base station among multiple base stations that can solve all the multi-card problems reported by the terminal as the second base station, and then generate indication information for indicating that the second base station can solve the multi-card problem. For example, the indication information can include the identifier of the second base station, and then carry the indication information in the measurement report to the first base station, so that the first base station can directly determine the second base station based on the indication information.

[0112] In one embodiment, the first information is carried in a HANDOVER REQUIRED signaling. Accordingly, the first information can be carried directly in the relevant signaling during the handover process without sending the first information separately, which is beneficial to saving communication resources.

[0113] In one embodiment, the first information is carried in a newly added information element IE of the handover requirement signaling, or is carried in a Source to Target TransparentContainer information element of the handover requirement signaling.

[0114] For example, it can be carried in at least one of the following:

[0115] Source NG-RAN Node to Target NG-RAN Node Transparent Container IE;

[0116] Source eNB to Target eNB Transparent Container IE;

[0117] Source RNC to Target RNC Transparent Container IE.

[0118] Figure 5 FIG. 1 is a schematic flow chart of another method for sending an instruction according to an embodiment of the present disclosure. Figure 4 As shown, in some embodiments, the method further includes:

[0119] In step S501, a configuration for resolving the multi-card problem is determined according to second information from the core network;

[0120] In step S502, corresponding configuration is performed for the terminal according to the configuration.

[0121] In one embodiment, after receiving the first information, the core network can send the relevant information of the multi-card problem carried by the first information to the second base station. The second base station can determine the configuration to solve the multi-card problem based on the relevant information of the multi-card problem, and then perform corresponding configuration for the terminal based on the configuration to solve the multi-card problem for the terminal.

[0122] Among them, the second base station performs corresponding configuration for the terminal, which can be performed indirectly, for example, sending the configuration to the core network, and then the core network carries it in the second information and sends it to the first base station, so that the first base station can solve the multi-card problem for the terminal according to the configuration, for example, sending the configuration to the terminal.

[0123] The second base station performs corresponding configuration for the terminal, which may be performed indirectly, for example, after the terminal switches to the second base station, the determined configuration is sent to the terminal.

[0124] It should be noted that the configurations for resolving the multi-card problem in all embodiments of the present disclosure, such as the configuration determined by the second base station, the recommended configuration for resolving the multi-card problem in the relevant information about the multi-card problem, etc., may be different for different multi-card problems. The terminal is configured accordingly according to the configuration for resolving the multi-card problem, and the time-frequency resources for the terminal to perform conflicting operations may be changed. For example, if the multi-card problem is a conflict between the communication operation of the first SIM card with the first base station and the paging message of the second SIM card monitoring the second base station (or other base stations), then the configuration for resolving the multi-card problem may be to temporarily suspend the time-frequency resources for the communication operation between the first SIM card and the first base station to give priority to the second SIM card monitoring the paging message.

[0125] In one embodiment, the second information is carried in HANDOVER COMMAND signaling.

[0126] In one embodiment, the second information is carried in a newly added information element of the handover command signaling, or is carried in a Target to Source TransparentContainer IE of the handover command signaling.

[0127] In one embodiment, the first base station can receive the switching command signaling sent by the core network and obtain the second information from the switching command signaling, for example, the second information can be obtained from the newly added information element of the switching command signaling, or the second information can be obtained from the target to source transparent container information element of the switching command signaling.

[0128] Figure 6 This is a schematic flow chart of a method for sending information according to an embodiment of the present disclosure. The method for sending information shown in this embodiment can be applied to a core network, which can communicate with a first base station, or with a terminal as a user equipment.

[0129] The terminals include, but are not limited to, mobile phones, tablet computers, wearable devices, sensors, unmanned aerial vehicles, IoT devices, and other communication devices. The first and second base stations include, but are not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The core network includes, but is not limited to, the core network in communication systems such as 4G base stations, 5G base stations, and 6G base stations.

[0130] like Figure 6 As shown, the information sending method may include the following steps:

[0131] In step S601, first information sent by a first base station is received, wherein the first information carries relevant information about a multiple SIM card problem of a terminal, and the first information is used to instruct the core network to send the relevant information about the multiple SIM card problem to the second base station;

[0132] In step S602, the information related to the multi-card problem is sent to the second base station.

[0133] In one embodiment, the terminal may currently access the first base station, for example, reside in a cell corresponding to the first base station (for example, in an idle state or an inactive state), or establish a connection with the first base station (for example, in a connected state).

[0134] When a terminal determines that a multi-card problem exists (currently exists or is predicted to occur), it can send the multi-card problem information to the base station. After receiving the multi-card problem information from the terminal, the base station can further determine the target base station to which the terminal should switch when performing a cell handover (e.g., cell reselection). In this embodiment, this is referred to as the second base station.

[0135] After determining the second base station, the first base station can carry the relevant information of the multi-card problem in the first information and send it to the core network to instruct the core network to send the relevant information of the multi-card problem to the second base station, thereby solving the multi-card problem for the terminal.

[0136] For example, the second base station may wait until the terminal switches to the second base station before resolving the multi-card problem for the terminal;

[0137] The second base station may also send the configuration for solving the multiple SIM card problem to the core network, which then forwards it to the first base station, so that the first base station can solve the multiple SIM card problem for the terminal according to the configuration for solving the multiple SIM card problem provided by the second base station.

[0138] According to an embodiment of the present disclosure, the first base station can send the multi-card problem of the terminal to the second base station to which the terminal needs to switch through the core network during the process of the terminal switching cells, so that the second base station can solve the multi-card problem for the terminal.

[0139] In one embodiment, the information related to the multi-card problem includes at least one of the following:

[0140] The multi-card problem;

[0141] Recommended configuration to resolve the described multiple card issue.

[0142] The relevant information about the multi-card problem carried by the first base station in the first information sent to the core network may include the multi-card problem itself, such as one or more of the above-mentioned types of multi-card problems; it may also include the recommended configuration of the multi-card problem determined by the first base station based on its own implementation. For example, when the first base station solved the multi-card problem for the terminal in the past, it can determine the historical configuration that successfully solved the multi-card problem for the terminal (which can be determined by the first base station itself or from other base stations), and then use the historical configuration as the recommended configuration.

[0143] In one embodiment, the method further comprises:

[0144] Sending the core network's recommended configuration for solving the multi-card problem to the second base station (which may be the same as or different from the recommended configuration determined by the first base station based on its own implementation for solving the multi-card problem).

[0145] The core network can also determine the recommended configuration of the multi-card problem based on its own implementation and send it to the second base station. For example, the core network can determine the historical configuration that successfully solved the multi-card problem for the terminal in the past process of solving the multi-card problem for the terminal, and then use the historical configuration as the recommended configuration.

[0146] In one embodiment, sending the information related to the multiple card problem to the second base station includes:

[0147] The handover request HANDOVER REQUEST signaling carries the relevant information of the multi-card problem and is sent to the second base station.

[0148] Accordingly, the relevant information about the multiple SIM card problem can be directly sent to the second base station using the relevant signaling in the switching process, without having to send the relevant information about the multiple SIM card problem to the second base station separately, which is conducive to saving communication resources.

[0149] In one embodiment, sending the information related to the multiple card problem to the second base station includes:

[0150] In response to the first information being carried in a source-to-target transparent container information element of the handover requirement signaling, the source-to-target transparent container information element is transparently transmitted to the second base station.

[0151] When the first information is carried in the source-to-target transparent container information element, the core network can directly transmit the source-to-target transparent container information element to the second base station, so that the second base station receives the first information; and when the first information is carried in other information elements of the switching request signaling, the core network can obtain relevant information about the multi-card problem from the first information, and then carry the relevant information about the multi-card problem in the newly added information element of the switching request signaling and send it to the second base station.

[0152] Figure 7 FIG is a schematic flow chart of another information sending method according to an embodiment of the present disclosure. Figure 7 As shown, the method further includes:

[0153] In step S701, third information sent by the second base station is received, wherein the third information carries a configuration of the second base station for solving the multi-card problem;

[0154] In step S702, the configuration of the second base station for solving the multi-card problem is carried in a second message and sent to the first base station.

[0155] In one embodiment, the second base station may determine a configuration for resolving the multi-card problem based on relevant information about the multi-card problem, and then resolve the multi-card problem for the terminal based on the configuration. The second base station may resolve the multi-card problem for the terminal based on the determined configuration by carrying the configuration in a third message and sending it to the core network, which then carries the configuration in a second message and sends it to the first base station. The first base station may then resolve the multi-card problem for the terminal based on the configuration, for example, by sending the configuration to the terminal.

[0156] In one embodiment, sending the configuration of the second base station for solving the multi-card problem in the second information to the first base station includes:

[0157] In response to the third information being carried in a target-to-source transparent container information element of a handover request acknowledgment signaling, transparently transmitting the target-to-source transparent container information element to the first base station;

[0158] In response to the third information being carried in the handover request confirmation signaling and not carried in the target-to-source transparent container information element, a configuration for the second base station to solve the multi-card problem is sent to the first base station via a handover command signaling.

[0159] When the third information is carried in the target-to-source transparent container information element, the core network can directly transmit the target-to-source transparent container information element to the first base station, so that the first base station receives the configuration to solve the multi-card problem; and when the third information is carried in other information elements of the switching request confirmation, the core network can obtain the configuration to solve the multi-card problem from the third information, and then carry the configuration to solve the multi-card problem in the newly added information element of the switching command signaling and send it to the first base station.

[0160] Figure 8 This is a schematic flow chart illustrating a method for resolving the multi-SIM card issue according to an embodiment of the present disclosure. The method for resolving the multi-SIM card issue illustrated in this embodiment can be applied to a second base station, which can communicate with the core network, as well as with the first base station and a terminal serving as a user equipment.

[0161] The terminals include, but are not limited to, mobile phones, tablet computers, wearable devices, sensors, unmanned aerial vehicles, IoT devices, and other communication devices. The first and second base stations include, but are not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The core network includes, but is not limited to, the core network in communication systems such as 4G base stations, 5G base stations, and 6G base stations.

[0162] like Figure 8 As shown, the multi-card problem solution may include the following steps:

[0163] In step S801, relevant information about a multi-SIM card problem of a terminal is received from a core network, and a configuration for resolving the multi-SIM card problem is determined based on the relevant information about the multi-SIM card problem.

[0164] In step S802, corresponding configuration is performed for the terminal according to the configuration.

[0165] The first information carries relevant information about the multi-card problem, and the first information is used to instruct the core network to send the relevant information about the multi-card problem to the second base station.

[0166] In one embodiment, the terminal may currently access the first base station, for example, reside in a cell corresponding to the first base station (for example, in an idle state or an inactive state), or establish a connection with the first base station (for example, in a connected state).

[0167] When a terminal determines that a multi-card problem exists (currently exists or is predicted to occur), it can send the multi-card problem information to the base station. After receiving the multi-card problem information from the terminal, the base station can further determine the target base station to which the terminal should switch when performing a cell handover (e.g., cell reselection). In this embodiment, this is referred to as the second base station.

[0168] After determining the second base station, the first base station can carry the relevant information of the multi-card problem in the first information and send it to the core network to instruct the core network to send the relevant information of the multi-card problem to the second base station. After receiving the relevant information of the multi-card problem, the second base station can determine the configuration to solve the multi-card problem based on the relevant information of the multi-card problem, and then perform corresponding configuration for the terminal based on the configuration, thereby solving the multi-card problem for the terminal.

[0169] Accordingly, the second base station can determine the multi-card problem that the terminal needs to solve during the process of the terminal switching cells, and then solve the multi-card problem for the terminal.

[0170] In one embodiment, performing corresponding configuration for the terminal according to the configuration includes:

[0171] Sending third information to the core network, wherein the third information carries a configuration of the second base station for solving the multi-card problem; and / or

[0172] In response to the terminal switching to the second base station, a configuration of the second base station for solving the multi-card problem is sent to the terminal.

[0173] In one embodiment, the second base station performs corresponding configuration for the terminal, which can be an indirect configuration, for example, the configuration for solving the multi-card problem is carried in the third information and sent to the core network, which is then forwarded to the first base station by the core network, so that the first base station solves the multi-card problem for the terminal according to the configuration for solving the multi-card problem provided by the second base station.

[0174] In one embodiment, the second base station performs corresponding configuration for the terminal, which can be an indirect configuration, for example, after the terminal switches to the second base station, the configuration for solving the multi-card problem is sent to the terminal, thereby solving the multi-card problem for the terminal, for example, carried in RRCReconfiguration signaling or RRCConnectionReconfiguration signaling and sent to the terminal.

[0175] In one embodiment, the third information is carried in a newly added information element of the handover request confirmation signaling, or is carried in a target-to-source transparent container information element of the handover request confirmation signaling.

[0176] Figure 9 FIG. 1 is a schematic flow chart showing another method of solving the multi-card problem according to an embodiment of the present disclosure. Figure 9 As shown, performing corresponding configuration for the terminal according to the configuration includes:

[0177] In step S901, the allowable delay for resolving the multi-card problem is determined;

[0178] In step S902, in response to the delay being less than the first preset delay, sending the third information to the core network;

[0179] In step S903, in response to the delay being greater than a second preset delay, and in response to the terminal being switched to the second base station, a configuration of the second base station for solving the multi-card problem is sent to the terminal;

[0180] The second preset delay is greater than or equal to the first preset delay.

[0181] In one embodiment, after receiving the relevant information about the multi-card problem sent by the core network, the second base station can choose to perform indirect configuration, such as sending the configuration for solving the multi-card problem to the first base station through the core network, or it can choose to perform direct configuration, such as waiting until the terminal switches to the second base station, and then solving the multi-card problem for the terminal based on the configuration. However, the time it takes for the terminal to switch to the second base station may be long, which may easily cause a large delay. For services that allow lower delays, it will be difficult to meet the requirements.

[0182] Based on this, after receiving relevant information about the multi-card problem, the second base station can determine the delay allowed for the multi-card problem. For example, the relevant information carries the service corresponding to the multi-card problem, such as the communication operation being performed by the first SIM card, which conflicts with the communication operation that the second SIM card needs to perform. The service corresponding to the multi-card problem can be the service corresponding to the communication operation that the second SIM card needs to perform, and the delay allowed for the multi-card problem is the delay allowed for the service corresponding to the multi-card problem.

[0183] If the delay allowed by the service is low, for example, less than the first preset delay, the third information carrying the configuration for solving the multi-card problem can be sent directly to the core network, so that the core network can send the configuration to the first base station as soon as possible, and then the first base station can solve the multi-card problem for the terminal as soon as possible, so as to solve the multi-card problem within the first preset delay range, so that the service corresponding to the multi-card problem can proceed smoothly.

[0184] If the service allows a low delay, for example, greater than the first preset delay, it is possible to wait until the terminal switches to the second base station, and then send the configuration of the second base station to the terminal to solve the multi-card problem. Accordingly, there is no need to forward it to the first base station through the core network, which is conducive to solving communication resources.

[0185] Figure 10 This is a schematic flow chart illustrating a method for solving the multi-SIM problem according to an embodiment of the present disclosure. The method for solving the multi-SIM problem illustrated in this embodiment is applicable to a terminal, which can function as a user equipment and communicate with a first base station, or with a second base station and a core network.

[0186] The terminals include, but are not limited to, mobile phones, tablet computers, wearable devices, sensors, unmanned aerial vehicles, IoT devices, and other communication devices. The first and second base stations include, but are not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The core network includes, but is not limited to, the core network in communication systems such as 4G base stations, 5G base stations, and 6G base stations.

[0187] like Figure 10 As shown, the multi-card problem solution may include the following steps:

[0188] In step S1001, a multi-card problem and information about a second base station are sent to a first base station, so that the first base station sends first information to a core network;

[0189] The first information carries relevant information about the multi-card problem, and the first information is used to instruct the core network to send the relevant information about the multi-card problem to the second base station.

[0190] In one embodiment, the terminal may currently access the first base station, for example, reside in a cell corresponding to the first base station (for example, in an idle state or an inactive state), or establish a connection with the first base station (for example, in a connected state).

[0191] When the terminal determines that a multi-card problem exists (currently exists or is predicted to occur), the terminal can send information about the multi-card problem and the second base station to the base station. After receiving the information about the multi-card problem of the terminal and the second base station, the base station can determine that relevant information about the multi-card problem needs to be sent to the second base station.

[0192] The first base station may carry the relevant information of the multi-card problem in the first information and send it to the core network, to instruct the core network to send the relevant information of the multi-card problem to the second base station, thereby solving the multi-card problem for the terminal.

[0193] For example, the second base station can wait until the terminal switches to the second base station before solving the multi-card problem for the terminal; the second base station can also send the configuration for solving the multi-card problem to the core network, and then the core network forwards it to the first base station, so that the first base station can solve the multi-card problem for the terminal according to the configuration for solving the multi-card problem provided by the second base station.

[0194] According to an embodiment of the present disclosure, the first base station can determine the multi-card problem that the terminal needs to solve, and the relevant information of the multi-card problem needs to be sent to the second base station, and then the relevant information of the multi-card problem can be sent to the second base station through the core network, so that the second base station can solve the multi-card problem for the terminal.

[0195] In one embodiment, sending information of the second base station to the first base station includes:

[0196] A measurement report is sent to the first base station, where the measurement report includes at least a measurement result of the second base station.

[0197] In one embodiment, when the terminal needs to switch cells, it can measure the current cell and the neighboring cells, generate a measurement report based on the measurement results, and then send the measurement report to the first base station. After receiving the measurement report, the first base station can determine the second base station to which the terminal needs to switch based on the measurement report.

[0198] The terminal can carry the multi-SIM problem in a measurement report and send it to the first base station, thereby eliminating the need to carry the multi-SIM problem report in a separate message, which is beneficial to solving the communication resource problem.

[0199] In one embodiment, the multi-card problem may occur before the terminal needs to switch cells, and is not reported to the first base station until the terminal needs to switch cells (the triggering reason is not the multi-card problem).

[0200] In one embodiment, the multi-card problem can trigger the terminal to switch cells. For example, after the terminal has a multi-card problem, if it determines that the current first base station cannot solve the multi-card problem, it can trigger the cell switching so as to access other base stations, and let other base stations solve the multi-card problem.

[0201] In one embodiment, the measurement result of the second base station includes at least one of the following:

[0202] a measurement result of the second base station's ability to resolve a multi-card problem;

[0203] A measurement result of the signal quality of the second base station.

[0204] In addition to carrying the multi-card problem, the measurement report can also carry the measurement results of the signal quality of multiple base stations (corresponding cells); and when the base station can broadcast its own ability to solve the multi-card problem, the terminal can also monitor the base station's ability to solve the multi-card problem, and report the monitoring results to the first base station in the measurement report, so that the first base station can determine which base stations have the ability to solve the multi-card problem reported by the terminal.

[0205] In one embodiment, the method further comprises:

[0206] receiving a configuration for resolving the multiple-card problem sent by the second base station;

[0207] The multiple card problem is solved according to the configuration.

[0208] In one embodiment, the terminal may directly or indirectly receive a configuration for resolving the multiple SIM card issue from the second base station, and then resolve the multiple SIM card issue based on the configuration. For example, based on the configuration for resolving the multiple SIM card issue, the terminal may temporarily suspend the time and frequency resources for communication between the first SIM card and the first base station to prioritize the second SIM card's monitoring of paging messages.

[0209] In one embodiment, the receiving, from the second base station, a configuration for resolving the multiple-card problem includes:

[0210] Receive the configuration sent by the first base station, wherein the configuration is sent by the second base station to the core network, and is sent by the core network to the first base station.

[0211] In one embodiment, the second base station can carry the configuration for solving the multi-card problem in the third information and send it to the core network, which is then forwarded to the first base station by the core network. The first base station then sends the configuration for solving the multi-card problem provided by the second base station to the terminal, and the terminal solves the multi-card problem based on the configuration.

[0212] In one embodiment, the receiving, from the second base station, a configuration for resolving the multiple-card problem includes:

[0213] In response to switching to the second base station, the configuration sent by the second base station is received.

[0214] In one embodiment, after being switched to the second base station, the terminal may directly or indirectly receive a configuration for solving the multiple-card problem from the second base station, and then solve the multiple-card problem based on the configuration.

[0215] Figure 11 FIG. 1 is a schematic flow chart showing another method of solving the multi-card problem according to an embodiment of the present disclosure. Figure 11 As shown, the method further includes:

[0216] In step S1101, in response to the multi-card problem being solved according to the configuration, information that the multi-card problem has been solved is sent to the second base station.

[0217] In one embodiment, after the terminal successfully solves the multi-card problem according to the configuration for solving the multi-card problem provided by the second base station, the terminal can send multi-card problem solved information to the second base station to inform the second base station that the terminal has successfully solved the multi-card problem according to the configuration provided by it, so that the second base station does not need to repeatedly send the configuration to the terminal; accordingly, if the second base station does not receive the multi-card problem solved information within a period of time after sending the configuration, or receives multi-card problem unresolved information, it can send the configuration to the terminal again, or determine a new configuration and send it to the terminal, so as to successfully solve the multi-card problem.
