DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application are further described in detail below with reference to the drawings.

[0019] As can be understood, terms such as "first", "second", etc., used in this application are used to delineate various concepts. However, unless otherwise specified, the concepts are not limited to the terms. The terms are used only to distinguish one concept from another.

[0020] First, a brief introduction of the nouns according to the embodiments of the present application will be given.

[0021] Multi-card function: Also called Multiple UMTS Subscriber Identity Module (MUSIM) function. When multiple USIM cards can be installed in a terminal and the terminal communicates using a network connection corresponding to the USIM cards, the terminal communicates using only a network connection corresponding to one USIM card at the same time. The terminal determines the multi-card function supported and / or permitted by the network device, then selects a method of supporting multiple USIM cards to communicate, and negotiates that the terminal will communicate using multiple USIM cards.

[0022] 1 is a block diagram illustrating a communication system according to an exemplary embodiment of the present application, which may include an Access Network (AN) 12 and a terminal 13.

[0023] The AN 12 includes a number of network devices 120. The network devices 120 may be base stations, which are devices deployed in an AN and used to provide wireless communication functions to terminals. The base stations may include various types of macro base stations, micro base stations, relay stations, and access points (APs). In systems using different wireless access technologies, devices with base station functions may have different names. For example, they are called eNodeB or eNB (Evolved Node B) in a Long Term Evolution (LTE) system, and gNodeB or gNB (the Next Generation Node B) in a 5G (Fifth Generation) NR-U (New Radio-based Access to Unlicensed Spectrum) system. As communication technologies evolve, the term "base station" may change. For convenience, in the embodiments of this application, the devices providing wireless communication functions to terminals 13 are collectively referred to as AN devices.

[0024] The terminal 13 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem with wireless communication capabilities, as well as various kinds of user equipment (UE), mobile stations (MS), terminal devices, etc. For convenience of description, the above-mentioned devices are collectively referred to as terminals. The AN device 120 communicates with the terminal 13 via an air interface technology (e.g., Uu interface).

[0025] The technical solutions in the embodiments of the present application can be applied to various kinds of communication systems. For example, Global System for Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, Advanced New Radio system, LTE-based Access to Unlicensed Spectrum (LTE-U) system, NR-U system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, Wireless Local Area Network (WiMAX) system, Wireless Local Area Network (WLAN), Wireless Local Area Network (WLAN), Wireless Local Area Network (WLAN), Wireless Local Area Network (WLAN), Wireless Local Area Network (WLAN), Wireless Local Area Network (LLO) system, ... Network (WLAN), Wireless Fidelity (WiFi), next generation communication systems, or other communication systems.

[0026] Generally speaking, traditional communication systems support a limited number of connections and are therefore easily implemented. However, with the development of communication technology, mobile communication systems can not only support traditional communication, but also support Device to Device (D2D) communication, Machine to Machine (M2M) communication, Machine Type Communication (MTC), Vehicle to Vehicle (V2V) communication, and Vehicle to Everything (V2X) communication systems, etc. The embodiments of the present application can also be applied to these communication systems or other communication systems.

[0027] In the related art, a network device can communicate with a terminal. When the terminal includes multiple USIM cards and only one USIM card of the multiple USIM cards in the terminal can be used for communication at the same time, the communication service of another USIM card is affected. Therefore, the concept of a multi-card function is proposed. The network device can negotiate with the terminal through the multi-card function supported and / or allowed by the network device, which is advantageous in not affecting or reducing the impact on the services of the multiple USIM cards in the terminal.

[0028] 2 is a flowchart showing an information transmission method according to an exemplary embodiment of the present application. The method is applied to the terminal and network device shown in FIG. 1, and includes at least one of the following:

[0029] Step 201: A network device sends function parameters to a terminal.

[0030] The capability parameters are used to indicate the multi-card capabilities supported and / or permitted by the network device. The network device sends the capability parameters to the terminal, and the terminal determines the multi-card capabilities supported and / or permitted by the network device based on the capability parameters. In an embodiment of the present application, the network device can send the capability parameters to the terminal, and the terminal communicates based on the multi-card capabilities supported and / or permitted by the network device.

[0031] The multi-card function will now be described.

[0032] The multi-card functionality supported and / or permitted by the network device includes at least one of the following:

[0033] (1) Supports or allows the addition of service information to paging messages.

[0034] The service information is used to indicate a service type corresponding to a data package that triggers a paging message, which indicates the type of service that triggers the paging message, which can be a text service, a voice service, a video service, etc.

[0035] The network device has a function for adding service information to the paging message, and can add service information to the paging message to be sent so as to indicate the service type corresponding to the data package that triggers the paging message.

[0036] When communicating with a terminal, a network device sends a paging message to the terminal, and when the terminal receives the paging message, the terminal responds to the paging message. The terminal can use multiple USIM cards. If the terminal receives a paging message of a first USIM card among the multiple USIM cards, it cannot determine whether it needs to switch to a network connection corresponding to the first USIM card to respond to the paging message. If the network device adds service information to the paging message, the terminal can determine a service type corresponding to the paging message based on the service information, and then determine whether to respond to the paging message.

[0037] Optionally, the network device adds a paging cause parameter to the paging message, and the paging cause parameter is used to indicate service information. After receiving the paging message, the terminal can read the paging cause parameter in the paging message, and then determine a service type according to the paging cause parameter, and further determine whether to respond to the paging message.

[0038] (2) Support or permit a terminal to switch from one USIM card to another USIM card to execute a service, and / or support or permit switching to time information in which a service is executed by another USIM card.

[0039] If the network device has a function of supporting or allowing a terminal to switch from one USIM card to another USIM card to execute a service, and / or a function of supporting or allowing a terminal to switch to time information at which a service is executed by another USIM card, the network device allows the terminal to switch from a current USIM card to another USIM card to execute a service.

[0040] A terminal switching from one USIM card to another USIM card to perform a service may refer to a terminal switching from USIM-1 to USIM-2 to perform a service, or a terminal switching from USIM-1 to USIM-3 to perform a service, or other types of switching, which are not limited in the embodiments of the present application.

[0041] The time information may be a length of time, a point in time, or the like.

[0042] When a network device communicates with a terminal, if the network device supports or permits the terminal to switch from a current USIM card to another USIM card for communication, the terminal can switch from the current USIM card to another USIM card by itself and access a network connection corresponding to the other USIM card to communicate.

[0043] In addition, if the network device supports or permits the terminal to switch to another USIM card during a certain period of time to execute a service, the terminal can switch to a network connection corresponding to the other USIM card during that period of time, either by itself or under the control of the network, to execute a service.

[0044] In an embodiment of the present application, multiple USIM cards in a terminal correspond to different network connections, and the network device informs the terminal that the network device has a function of supporting or allowing the terminal to switch from one USIM card to another USIM card to execute a service, and / or a function of supporting or allowing the terminal to switch to time information at which a service is executed by another USIM card. The network device can interact with the terminal and allow the terminal to leave the network corresponding to the current USIM card (e.g., disconnect from the current network) and access the network corresponding to the other USIM card (e.g., establish or restore a connection with the network corresponding to the other USIM card).

[0045] Optionally, the network device may negotiate Frequency Division Multiplexing or Time Division Multiplexing with the terminal so that the terminal can switch from a current USIM card to another USIM card, thereby achieving a bi-pass effect between the network device and the terminal.

[0046] Frequency division multiplexing may refer to the fact that multiple USIM cards in a terminal can be used to perform services at different frequencies. After a network device negotiates frequency division multiplexing with a terminal, multiple USIM cards in the terminal can be used to perform communication at different frequencies, respectively, thereby realizing a bi-pass effect.

[0047] Time division multiplexing may refer to the fact that multiple USIM cards in a terminal can be used to perform services at different times. After a network device negotiates time division multiplexing with a terminal, different time intervals can be divided through time division multiplexing, so that multiple USIM cards in a terminal can be used to perform communication in different time intervals, thereby realizing a bi-pass effect.

[0048] (3) Supporting or allowing data transmitted to another USIM card or service information corresponding to the above data to be transmitted to the terminal via a network connection corresponding to the current USIM card.

[0049] The network device has a function of transmitting data or service information corresponding to the data of another USIM card to the terminal via a network connection corresponding to the current USIM card, and the terminal has a function of receiving data or service information corresponding to the data of the other USIM card via the network connection corresponding to the current USIM card.

[0050] The network device receives data or service information corresponding to the data from another USIM card. Because the terminal currently includes multiple USIM cards and communicates using a network connection corresponding to the current USIM card, the network device transmits the received data or service information corresponding to the data to the terminal via the network connection corresponding to the current USIM card, thereby ensuring that the terminal can receive the data or service information corresponding to the data via the network connection corresponding to the current USIM card.

[0051] The data may be downlink (DL) service data, or other types of data.

[0052] For example, when the terminal communicates using USIM-1, the network device may receive DL service data of USIM-2 and transmit the DL service data of USIM-2 to the terminal via a network connection corresponding to USIM-1.

[0053] Optionally, the network device realizes a network channel (e.g., a user plane channel) corresponding to one USIM card accessing a network corresponding to another USIM card through a dedicated gateway (e.g., a Third Generation Partnership Project (3GPP) gateway). The network device can send data or service information corresponding to data sent to the other USIM card to the terminal through the dedicated gateway in the network corresponding to the current USIM card.

[0054] The 3GPP gateway may be a Non-3GPP Inter Working Function (N3IWF) gateway, an Enhanced Packet Data Gateway (ePDG), or other gateway.

[0055] For example, as shown in FIG. 3, the terminal includes USIM-1 and USIM-2. In addition, USIM-1 is registered in a network corresponding to USIM-1 or has established a connection with the network corresponding to USIM-1, and USIM-2 is registered in a network corresponding to USIM-2 or has established a connection with the network corresponding to USIM-2. The terminal can establish a secure connection with an N3IWF gateway through the network corresponding to USIM-1. Since the N3IWF gateway is in the network corresponding to USIM-2, data or service information corresponding to the data in the network corresponding to USIM-2 can be transmitted to the terminal through the established secure connection. In this way, the terminal can receive data or service information corresponding to the data transmitted by the network corresponding to USIM-2 even if it only maintains a connection with the network corresponding to USIM-1.

[0056] Alternatively, if the two USIM cards are registered in the same network, the network device receives DL service data of USIM-1, notifies the currently used USIM-2, and notifies the USIM-1 that it needs to receive DL service data via USIM-2, so that the USIM-1 can receive DL service data via a corresponding network connection.

[0057] (4) Supporting or allowing the terminal to send a request message so that the terminal leaves the network connection corresponding to the current USIM card within the reference time period.

[0058] The reference time zone can be determined when the terminal leaves the network connection corresponding to the current USIM card, or can be determined at a time before that. The method of determining the reference time zone may be obtained through interactive negotiation between the terminal and the network, or may be a default value.

[0059] When the terminal needs to leave the network connection corresponding to the current USIM card, the terminal sends a request message to a network device, and the network device receives the request message and determines that the terminal leaves the network connection corresponding to the current USIM card. Furthermore, the terminal can access the network connection corresponding to another USIM card.

[0060] The reference time period is the time period during which the terminal accesses a network connection corresponding to another USIM card.

[0061] If the network device has a function of replying to a request message for the terminal to be permitted to leave the network connection corresponding to the current USIM card, when the network device receives a request message for the terminal to leave the network connection corresponding to the current USIM card within a reference time period, the network device can reply to a message for the terminal to be permitted to leave the network connection corresponding to the current USIM card.

[0062] Or, the network device receives the request message sent by the terminal but does not reply to the terminal, and the terminal may leave the network corresponding to the current USIM card by itself.

[0063] (5) Supporting or allowing to determine whether to send a paging message to a terminal based on a service list.

[0064] The service list includes service information indicating that a paging message is prohibited from being sent by a network device to the terminal when the terminal is in a radio resource control inactive (RRC_Inactive) state and / or a connection management idle (CM-IDLE) state.

[0065] The network device has a function of determining whether to send a paging message to the terminal according to the service list, and after the network device informs the terminal of the function, the terminal can directly respond to the paging message received from the network device.

[0066] After determining the service information that needs to page the terminal, the network device first determines whether the service information is service information indicating that sending a paging message is prohibited based on a service list. If the network device determines that the service information is service information indicating that sending a paging message is prohibited, it does not send a paging message corresponding to the service to the terminal. If the network device determines that the service information is not service information indicating that sending a paging message is prohibited, it sends a paging message corresponding to the service to the terminal. The terminal determines that the network device has a function of determining whether to send a paging message to the terminal based on a service list. When the terminal receives a paging message from the network device, it directly determines that the terminal needs to respond to the paging message, so as to avoid a situation where it cannot determine whether to respond to the paging message.

[0067] Alternatively, the service list may be obtained by the network device from a server, obtained by the network device based on a contract message, configured by the network device itself, or sent to the network device by a terminal.

[0068] Optionally, there are multiple ways for the network device to send the function parameters to the terminal. Step 201 includes any one of steps 2011 to 2013.

[0069] Step 2011: The network device sends a broadcast message to a terminal, where the broadcast message includes capability parameters.

[0070] The network device adds the capability parameters to a broadcast message sent to the terminal. The terminal receives the broadcast message sent by the network device, reads the capability parameters from the broadcast message, and determines the multi-card capabilities supported or permitted by the network device.

[0071] The broadcast message may be a system broadcast message of each cell or other broadcast message.

[0072] Step 2012: The network device sends a Non-access Stratum (NAS) message to the terminal, where the NAS message includes capability parameters.

[0073] The network device adds the capability parameters to the NAS message sent to the terminal. The terminal receives the NAS message sent by the network device, reads the capability parameters from the NAS message, and further determines the multi-card capability supported or allowed by the network device.

[0074] The NAS message may be a registration response message, a Protocol Data Unit (PDU) session establishment message, a PDU session modification message, etc.

[0075] Step 2013: The network device sends an Access Stratum (AS) message to the terminal, where the AS message includes capability parameters.

[0076] The network device adds the capability parameters to the AS message sent to the terminal. The terminal receives the AS message sent by the network device, reads the capability parameters from the AS message, and further determines the multi-card capability supported or permitted by the network device.

[0077] The AS message may be a Radio Resource Control (RRC) message, or other message, etc.

[0078] Step 202: The terminal receives the function parameters sent by the network device.

[0079] Step 203: The terminal communicates based on the multi-card functionality supported and / or permitted by the network device.

[0080] The terminal can receive the capability parameters sent by the network device and determine a multi-card capability supported or permitted by the network device based on the received capability parameters, and further communicate using one USIM card of the multiple USIM cards based on the multi-card capability supported or permitted by the network device.

[0081] Optionally, the terminal communicating using one USIM card of the multiple USIM cards includes a terminal operation determined by the terminal based on the multi-card capability and / or a network selection policy determined by the terminal based on the multi-card capability.

[0082] Optionally, the terminal operation determined by the terminal based on the multi-card capability includes at least one of the following:

[0083] (1) The terminal reads the service information in the paging message and determines whether to respond to the service information.

[0084] (2) The device can switch from the current USIM card to another USIM card on its own and access the network connection corresponding to the other USIM card to communicate.

[0085] (3) The terminal can receive data or service information corresponding to the data of another USIM card via the current USIM card.

[0086] (4) The terminal sends a request message to the network device to notify the network device that the terminal can leave the network connection corresponding to the current USIM card.

[0087] (5) The terminal may send a service list to the network device to instruct the network device whether or not to send a paging message to the terminal in the RRC_Inactive state and / or the CM-IDLE state.

[0088] Optionally, the terminal may determine a network selection policy based on at least one type of multi-card capability.

[0089] The network selection policy includes determining an accessed cell and / or determining a selected Public Land Mobile Network (PLMN), and may be cell selection, cell reselection, PLMN selection, etc. For example, when the terminal needs to perform one or more of the functions 1 to 5 above, it selects to reside in a network supporting the function or selects to initiate a connection with a network supporting the function. The functions that need to be performed by the terminal may be configured by a terminal user, or may be configured by the network, or may be configured locally.

[0090] It should be noted that the network device in the embodiment of the present application is merely an example for illustration. In another embodiment, the network device includes a core network (CN) and a base station. As shown in FIG. 4, step 201 may include steps 211 to 221.

[0091] Step 211: The CN sends function parameters to the base station.

[0092] Alternatively, in the registration process, the CN gateway uses an N2 request message to send the capability parameters to the base station, or when the CN gateway sends a paging message to the base station, it carries the capability parameters in the paging message.

[0093] Step 221: The base station sends function parameters to the terminal.

[0094] Correspondingly, step 202 is replaced by step 212 in which the terminal receives the capability parameters sent by the base station.

[0095] The network device in the embodiment of the present application can send the multi-card function supported and / or permitted by the network device to the terminal. The terminal can negotiate with the network device through the multi-card function supported and / or permitted by the network device to adjust the communication of the multiple USIM cards in the terminal. This is advantageous in that it does not affect the services of the multiple USIM cards in the terminal or reduces the impact on the services. In addition, since it does not affect the services of the multiple USIM cards or reduces the impact on the services, it can reduce the waste of data between the network device and the terminal due to the inability to process the services of the USIM cards, and further reduce the additional overhead of the network device and the terminal.

[0096] In an alternative embodiment based on Fig. 2, Fig. 5 is a flowchart illustrating a method for transmitting a request message according to an exemplary embodiment of the present application. In this embodiment, before step 201, the method further includes:

[0097] Step 501: A terminal sends a request message to a network device.

[0098] The request message is used to instruct the acquisition of a multi-card function supported and / or permitted by the network device. Before the network device sends the function parameters to the terminal, the terminal sends a request message to the network device to acquire the multi-card function supported and / or permitted by the network device from the network device.

[0099] Optionally, the request message includes multi-card capabilities supported and / or required by the terminal.

[0100] When the terminal requests to obtain the multi-card capabilities supported and / or permitted by the network device, the terminal transmits the multi-card capabilities supported and / or requested by the terminal to the network device, and the network device can then determine the multi-card capabilities supported and / or permitted by the network device based on the multi-card capabilities supported and / or requested by the terminal in the request message.

[0101] The multi-card features supported and / or required by the terminal include at least one of the following:

[0102] (1) Supports or requires reading service information in paging messages.

[0103] The service information is used to indicate the service type corresponding to the data package that triggers the paging message.

[0104] The capability of supporting or allowing the terminal to read the service information in the paging message corresponds to the capability of supporting or allowing the network device to add the service information to the paging message, which will not be repeated here.

[0105] (2) Supporting or requiring switching from one USIM card to another USIM card to execute a service, and / or supporting or requiring switching of time information at which a service is executed by another USIM card.

[0106] The function of the terminal supporting or allowing switching from one USIM card to another USIM card to execute a service and / or supporting or allowing switching to time information at which a service is executed by another USIM card corresponds to the function of the network device supporting or allowing the terminal to switch from one USIM card to another USIM card to execute a service and / or switching to time information at which a service is executed by another USIM card, which is not repeated here.

[0107] (3) Supporting or requiring receiving data or service information corresponding to data of another USIM card via a network connection corresponding to the current USIM card.

[0108] The function of supporting or allowing the terminal to receive data or service information corresponding to the data of another USIM card via a network connection corresponding to the current USIM card corresponds to the function of supporting or allowing the network device to transmit data or service information corresponding to the data transmitted to another USIM card via a network connection corresponding to the current USIM card to the terminal, which is not repeated here.

[0109] (4) Support or request to send a request message to a network device to leave the network connection corresponding to the current USIM card within the reference time period.

[0110] The function of supporting or allowing the terminal to send a request message to the network device so as to leave the network connection corresponding to the current USIM card within the reference time period corresponds to the function of the network device supporting or allowing the terminal to send a request message so as to leave the network connection corresponding to the current USIM card within the reference time period, which is not repeated here.

[0111] In addition, when the terminal needs to leave the network connection corresponding to the current USIM card, the terminal sends a request message to the network device to request the terminal to leave the network connection corresponding to the current USIM card. If the network device allows the terminal to leave, it returns a reply message to allow the terminal to leave.

[0112] The request message includes instruction information for instructing the terminal to leave the network connection corresponding to the current USIM card, to instruct the network device that the terminal needs to leave the network connection corresponding to the current USIM card.

[0113] The terminal transmits a request message to the network device, and the network device transmits a reply message to the terminal based on instruction information in the received request message instructing the terminal to leave the network connection corresponding to the current USIM card, and the terminal leaves the network connection corresponding to the current USIM card based on instruction information in the reply message permitting the terminal to leave.

[0114] Additionally, the request message further includes at least one of a time period away from the connection or a service list.

[0115] Since the terminal has left the network connection corresponding to the current USIM card, the network device needs to determine whether to page the terminal when receiving the service data of the USIM card. The terminal adds the time period during which the terminal is away from the connection and the service list to the request message, and the network device can determine whether to page the terminal based on at least one of the time period during which the terminal is away from the connection or the service list.

[0116] The terminal adds the time period during which the terminal is away from the connection to the request message it sends, and the network device can determine the time when the terminal returns based on the time period. If the network device receives a paging message during the time period during which the terminal is away from the connection, it needs to page the terminal.

[0117] The terminal may also add a service list in the request message sent by the terminal, the service list including service information indicating that the network device is prohibited from sending a paging message to the terminal when the terminal is in RRC_Inactive state and / or CM-IDLE state. The network device may determine whether to page the terminal based on the service list during the time period when the terminal is off-hook.

[0118] (5) Supporting or requiring a service list to be sent to a network device, so that the network device determines whether to send a paging message to the terminal based on the service list.

[0119] The service list includes service information indicating that a paging message is prohibited from being sent by the network device to the terminal when the terminal is in an RRC_Inactive state and / or a CM-IDLE state.

[0120] In an embodiment of the present application, the terminal may generate service information indicating that a paging message is prohibited from being sent by a network device to the terminal when the terminal is in an RRC_Inactive state and / or a CM-IDLE state. When the terminal is in an RRC_Inactive state and / or a CM-IDLE state, if the network device receives service information in the service list, the network device does not send a paging message corresponding to the service information to the terminal.

[0121] Alternatively, in this application, a multi-card function supported by a terminal can be considered to be a multi-card function permitted by the terminal.

[0122] Alternatively, the terminal may use multiple methods to send a request message to the network device, where the request message may be a NAS message or an AS message, such as a registration request or an RRC establishment request message, etc. Step 501 may include step 5011 or step 5012.

[0123] Step 5011: The terminal sends a registration request to the network device.

[0124] The registration request includes a request message. The terminal adds the request message to the registration request. Then, the network device receives the request message and adds the multi-card capabilities supported and / or permitted by the network device to a registration response message.

[0125] Step 5012: The terminal sends an RRC message to the network device.

[0126] The RRC message includes a request message. The terminal adds the request message to the RRC message. Then, the network device receives the request message and adds the multi-card capabilities supported and / or allowed by the network device to the RRC message.

[0127] For example, the RRC message may be an RRC establishment request message, or another message.

[0128] Step 502: The network device receives a request message sent by a terminal.

[0129] The network device receives the request message sent by the terminal, and performs a subsequent step of sending function parameters to the terminal based on the received request message.

[0130] It should be noted that performing steps 501-502 in the embodiment of the present application is merely an example for illustration purposes. In another embodiment, when step 501 includes step 5011, step 502 includes the network device receiving a registration request message sent by the terminal.

[0131] However, if step 501 includes step 5012, step 502 includes the network device receiving an RRC establishment request message sent by the terminal.

[0132] In an embodiment of the present application, a terminal requests to obtain a multi-card function supported and / or permitted by a network device, so that when the network device needs to indicate a multi-card function, the terminal can obtain the multi-card function sent by the network device, and can further coordinate communication of multiple USIM cards, and improve the accuracy of communication using multiple USIM cards.

[0133] In an alternative embodiment based on Fig. 2, Fig. 6 is a flowchart illustrating a method for transmitting function coverage according to an exemplary embodiment of the present application. In this embodiment, the method further includes:

[0134] Step 601: The network device sends multi-card function coverage information to the terminal.

[0135] The network device may also send function parameters to the terminal and instruct the terminal on the application range of these function parameters.The network device sends multi-card function application range information to the terminal.

[0136] The coverage information is used to indicate the coverage of the multi-card function of the network device, and the coverage information includes different types of information to indicate the coverage of the multi-card function of the network device.

[0137] Optionally, the coverage information includes at least one of the following:

[0138] (1) Location information used to indicate the location where the multi-card function supported by the network device is applied.

[0139] The location information may be a Tracking Area Identity (TAI) list, a cell list, a Global Positioning System (GPS) coordinate, or a base station node list, etc.

[0140] The terminal can receive the location information and determine a location supported by the network device based on the location information. When the terminal is in a location indicated by the location information, the terminal can determine a multi-card function supported and / or permitted by the network device.

[0141] For example, when the location information is a TAI list, the terminal determines a tracking area corresponding to each TAI according to the TAIs included in the TAI list, and when the terminal is in the tracking area, the terminal supports a multi-card function.

[0142] (2) Radio Access Type (RAT) information used to indicate the radio access type (RAT) to which the multi-card function is applied.

[0143] The RAT information may include the type of base station that the Radio Access Network (RAN) accesses, such as an LTE base station and an NR base station.

[0144] For example, if the RAT to which the multi-card function is applied is an NR type, the function is enabled if the terminal is currently connected to an NR base station.

[0145] (3) Time information used to indicate the time period during which the multi-card function is applied.

[0146] For example, when the terminal receives the time information, it can obtain the time period indicated by the time information and determine that the multi-card function is applicable in the time period.

[0147] Step 602: The terminal receives coverage information of the multi-card function.

[0148] The terminal can receive the coverage information of the multi-card function, and determine the coverage of the multi-card function according to the coverage information, and when the terminal is within the coverage range, can communicate based on the multi-card function.

[0149] In an embodiment of the present application, the terminal can determine a multi-card function supported and / or permitted by the received network device, and then determine the application scope of the multi-card function. If within the application scope, the terminal can adjust the communication of multiple USIM cards based on the multi-card function, thereby improving the accuracy rate of communication by the terminal based on the multi-card function.

[0150] The first point that needs to be explained is that in the embodiment of the present application, the applicability information of the multi-card function and the parameter information are included in different messages, which is merely an example for explanation. In another embodiment, the applicability information of the multi-card function and the parameter information are included in the same message, and the network device and the terminal do not need to perform steps 501-502, and the network device can also send the applicability information of the multi-card function when sending the function parameters to the terminal, and does not need to send the applicability information of the multi-card function separately.

[0151] The second point that needs to be explained is that in the embodiment of the present application, the network device sends the coverage information of the multi-card function to the terminal, which is just an example for explanation. In another embodiment, the terminal can determine the coverage information based on a default or static setting, that is, the network device does not need to send the coverage information of the multi-card function to the terminal, and the terminal itself can determine the coverage information of the multi-card function, and the coverage information of the multi-card function does not need to be indicated by the network device. This can reduce the message overhead and also improve the accuracy of the terminal's communication based on the multi-card function.

[0152] 7 is a flowchart illustrating an information transmission method according to an exemplary embodiment of the present application. Referring to FIG. 7, the method is applied between a CN and a base station. The method includes:

[0153] Step 701: The CN sends function parameters to the base station.

[0154] The capability parameter is used to indicate the multi-card capabilities supported and / or permitted by the network device.

[0155] Optionally, in the registration process, the CN sends an N2 request message to the base station, where the N2 request message includes capability parameters.

[0156] Or, the CN sends a paging message to the base station, where the paging message includes the capability parameters.

[0157] Step 702: The base station receives function parameters.

[0158] Step 703: The base station performs operations based on the multi-card features supported and / or permitted by the network device.

[0159] The base station determines the operation of the process of communicating with the terminal based on the multi-card capabilities supported and / or permitted by the network device.

[0160] The operations performed by the base station include at least one of the following:

[0161] (1) The base station adds service information to the paging message.

[0162] The base station adds the service information to the paging message is similar to the base station adds the service information to the paging message in the above embodiment, so it is not repeated here.

[0163] (2) The base station allows the terminal to switch from one USIM card to another USIM card to execute a service, and / or to switch to time information at which a service is executed by another USIM card.

[0164] The process of the base station allowing the terminal to switch from one USIM card to another USIM card to execute a service and / or the time information at which the service is executed by another USIM card is similar to the process in the above embodiment and is therefore not repeated here.

[0165] (3) The base station can transmit the data or service information corresponding to the data transmitted to another USIM card to the terminal via a network connection corresponding to the current USIM card.

[0166] The process in which a base station can transmit data or service information corresponding to data transmitted to another USIM card to a terminal via a network connection corresponding to a current USIM card is similar to the process in the above embodiment and will not be repeated here.

[0167] (4) The base station receives the request message sent by the terminal and allows the terminal to leave the network connection corresponding to the current USIM card within the reference period.

[0168] The process of the base station receiving the request message sent by the terminal and allowing the terminal to leave the network connection corresponding to the current USIM card within the reference period is similar to the process in the above embodiment, and therefore will not be repeated here.

[0169] (5) The base station determines whether to send a paging message to the terminal based on the service list.

[0170] The process of the base station determining whether to send a paging message to the terminal based on the service list is similar to the process in the above embodiment, and therefore will not be repeated here.

[0171] In an embodiment of the present application, the CN sends the multi-card capabilities supported and / or permitted by the network device to the base station. The base station can adjust the communication of the multiple USIM cards in the terminal based on the multi-card capabilities supported and / or permitted by the network device. This is advantageous in that it does not affect the services of the multiple USIM cards in the terminal or reduces the impact on the services. In addition, since it does not affect the services of the multiple USIM cards or reduces the impact on the services, it can reduce the waste of data between the base station and the terminal due to the inability to process the services of the USIM cards, and further reduce the additional overhead of the base station and the terminal.
