Description

Technical Field

[0001] This disclosure relates to the field of mobile communication technology, and in particular to a method, apparatus and communication device for exchanging multi-user identification card characteristic information. Background Technology

[0002] Most user equipment (UE) currently supports multiple subscriber identity cards (SIM cards), allowing different SIM cards to handle different services. For example, depending on the services and fees offered by different operators, users can choose to use SIM card 1 for voice services and SIM card 2 for data services.

[0003] In related technologies, to ensure the reliability of various UE services, it is proposed that the UE needs to report its current capabilities to the network. For example, during the capability registration and reporting phase, the UE sends the features of all multi-user identification cards (Multi-User Authentication Cards) supported by the UE to the network device. After receiving the information, the network device then informs the UE which Multi-User Authentication Card features the network supports. Subsequently, both parties process services based on the commonly supported Multi-User Authentication Card features.

[0004] When a UE supports a large number of multi-user identification card features, the UE needs to utilize more resources to negotiate multi-user identification card features with network devices, which wastes resources. Summary of the Invention

[0045] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0046] The relevant technology proposes that the UE needs to report its current capabilities to the network. However, when the UE supports multiple multi-user identification card features, the UE needs to utilize more resources to negotiate these features with the network equipment, thus wasting resources.

[0047] This disclosure considers the usage scenarios of various sub-features within the multi-user identification card (Multi-User Identification Card) feature set. Since some sub-features do not require UE initiation—that is, the network device does not need to know whether the UE supports the sub-feature—a method, apparatus, and communication device for exchanging Multi-User Identification Card feature information is proposed. In this disclosure, the UE only needs to report to the network device whether it supports Multi-User Identification Card features, and then the network device returns the supported Multi-User Identification Card features to the UE, significantly reducing the resources occupied during Multi-User Identification Card feature negotiation between the UE and the network device.

[0048] In this disclosure, the user identification card can be any card that can uniquely identify a user. For example, it can be a Subscriber Identity Module (SIM) card, or a Universal Subscriber Identity Module (USIM) card, etc. The following, in conjunction with various embodiments, provides a method, apparatus, and communication device for exchanging multi-user identification card characteristic information according to embodiments of this disclosure.

[0049] Figure 1 This is a flowchart illustrating another method for interacting with multi-user identification card feature information provided in an embodiment of this disclosure. This method can be executed by a UE. Figure 1 As shown, the method for interacting with multi-user identification card feature information includes the following steps:

[0050] Step 101: Send first indication information to the access network device. The first indication information is used to determine whether the UE is currently in a multi-user identification card state.

[0051] Optionally, in this disclosure, the UE can first determine the registration status of each local user identification card. If at least two user identification cards are in a normal registration state, it can be determined that the UE is currently in a multi-user identification card state, that is, it supports the multi-user identification card feature; otherwise, it can be determined that the UE is not currently in a multi-user identification card state, that is, it does not support the multi-user identification card feature.

[0052] In this disclosure, the UE can negotiate resources and send the first indication information to the access network device through specified multi-user identification card features. Alternatively, it can carry user identification card status information in other information. For example, the UE can send the first indication information to the access network device through a registration request, a service request, a location update request, etc., and this disclosure does not limit this.

[0053] Optionally, in order to reduce the resources occupied when the UE negotiates the multi-user identification card feature with the network device, in this disclosure, whether the UE is currently in multi-user identification card status can be indicated by the bit value specified by the first indication information.

[0054] Alternatively, since multi-user identification card (Multi-User Identification Card) features may include at least one of the following: paging cause, busy indication, multi-card departure, filtering rules, and paging collision avoidance, the UE can use different values ​​of specified bits to represent the specific Multi-User Identification Card features supported by the UE. For example, when the UE supports the BUSYindication feature, the specified bit can be 1; when the UE supports the Filtering feature, the specified bit can be 2; when the UE supports the Paging Collision Avoidance feature, the specified bit can be 3; when the UE supports all Multi-User Identification Card features, the specified bit can be 4, and so on. This disclosure does not limit this.

[0055] The Pagingcause feature indicates that the network adds a paging reason value when sending a paging request to the UE. A value of 1 indicates a voice service, and the UE can determine whether to respond to the paging upon receiving this value. The BUSYindication feature indicates that when SIM 1 in the UE is engaged in a service and SIM 2 receives a paging message, if the UE decides not to respond to SIM 2's paging, it will send a busy indication to the network. The network can then know that the UE has successfully received the paging and can stop paging. The Filtering feature indicates that when SIM 1 in the UE sends filtering rules to the network, the network can filter downlink data sent to SIM 1 according to the filtering rules. The Pagingcollisionavoidance feature indicates that when SIM 1 and SIM 2 in the UE are in idle state, they periodically listen for paging from their respective networks, resulting in overlapping listening resources and mutual interference. Multi-card departure refers to a situation where User Identification Card 1 (UIC1) is performing a service, and UIC2 receives a paging message. If the UIC1 decides to respond to the paging message from UIC2, then UIC1 needs to leave the network where it is performing the service.

[0056] It should be noted that the above-mentioned multi-user card identification features are merely illustrative examples, and any other multi-user identification card features not mentioned can also be interacted with through the interaction methods in this disclosure.

[0057] Optionally, the specified bit can be a bit in a specified multi-user identification card feature information negotiation message, or it can be a bit in a registration request, service request, or location update request.

[0058] Optionally, to further reduce the resources occupied by the UE when negotiating the multi-user identification card (MPIC) feature with the network device, in this disclosure, the UE may only include the first indication information in the registration request, service request, or location update request when it is in MPIC mode, i.e., when it supports the MPIC feature. When it does not support the MPIC feature, the first indication information is not included in the registration request, service request, or location update request. That is, the format of the registration request, service request, or location update request sent by the UE when it supports the MPIC feature is different from the format of the registration request, service request, or location update request sent when it does not support the MPIC feature.

[0059] It should be noted that the bit specified above can be a single bit or multiple bits, and this disclosure does not limit this.

[0060] Step 102: Receive second indication information sent by the access network device. The second indication information is used to indicate the multi-user identification card feature information supported by the core network device and / or the access network device.

[0061] Optionally, the UE can receive the second indication information sent by the access network device through a specified multi-user identification card feature information exchange message, or it can parse the registration reception message or service response message to obtain the second indication information sent by the access network device.

[0062] Optionally, in order to realize the interaction and synchronization of multi-user identification card feature information between the UE and the network device, after the UE sends the first indication information to the access network device, the access network device can forward the first indication information to the core network device, so that the core network device can send the second indication information to the UE according to the multi-user identification card feature information supported by the access network device and / or the core network device.

[0063] Since the multi-user identification card feature information may include multiple pieces of information, the form of the second indication information received by the UE may also be varied.

[0064] For example, different combinations of SIM card feature information correspond to different types of second indication information. Type A second indication information indicates that the access network equipment and core network equipment support all multi-SIM card feature information; Type B second indication information indicates that the access network equipment and core network equipment support paging reason and busy indication; Type C second indication information indicates that the access network equipment and core network equipment support busy indication and multi-SIM card departure, etc. Therefore, when the UE obtains Type A second indication information, it can determine that the access network equipment and core network equipment support all multi-SIM card feature information.

[0065] Alternatively, different user identification card (SIM) feature information corresponds to different values ​​of specified bits in the second indication information. That is, different values ​​of specified bits in multi-SIM feature information interaction messages, registration reception messages, or service response messages represent different multi-SIM feature information supported by access network devices and / or core network devices.

[0066] For example, when access network devices and core network devices support the BUSYindication feature, this bit can be set to 1; when access network devices and core network devices support the Filtering feature, this bit can be set to 2; when access network devices and core network devices support the Pagingcollisionavoidance feature, this bit can be set to 3, and so on. This disclosure does not limit this.

[0067] Optionally, after determining the multi-user identification card (MIC) feature information supported by the access network equipment and the core network equipment, the UE can update its local MIC feature information so that it can control the subsequent communication process with the network side based on the updated MIC feature information.

[0068] For example, if the UE supports the BUSYindication feature and determines that the access network device does not support BUSYindication based on the second indication information returned by the access network device, then the UE can disable or delete the local BUSYindication, so that when the service triggers BUSYindication, it will not send BUSYindication to the access network device.

[0069] Alternatively, if the UE supports the BUSYindication feature and determines, based on the second indication information returned by the access network device, that both the access network device and the core network device support BUSYindication, then the UE can send BUSYindication to the access network device when the service triggers BUSYindication.

[0070] In the multi-user identification card feature information interaction method of this disclosure embodiment, the UE only sends first indication information to the access network device to determine whether it is currently in a multi-user identification card state during the multi-user identification card feature information interaction with the network side, thereby saving resources used in the negotiation process.

[0071] Figure 2 This is a flowchart illustrating another method for interacting with multi-user identification card feature information provided in an embodiment of this disclosure. This method can be executed by a UE. Figure 2 As shown, the method for interacting with multi-user identification card feature information includes the following steps:

[0072] Step 201: Determine the value of the specified bit in the first indication information based on whether the current state is a multi-user identification card.

[0073] In this disclosure, in order for the network side to accurately determine the current state of the UE, regardless of whether the UE is currently in a multi-user identification card (Multi-User Authentication Card) state, the UE can send first indication information to the access network device to indicate whether the UE is currently in a Multi-User Authentication Card (Multi-User Authentication Card) state.

[0074] Optionally, in order to reduce the resources occupied when the UE negotiates the multi-user identification card feature with the network device, in this disclosure, whether the UE is currently in the multi-user identification card state can be indicated by different values ​​of the bits specified in the first indication information.

[0075] For example, when the UE determines that it is currently in a multi-user identification card state, that is, when it can support multi-user identification card features, it can set the value of the specified bit to 1; otherwise, it can set the value of the specified bit to 0, or any non-1 value.

[0076] Alternatively, since multi-user identification card (Multi-User Identification Card) features may include at least one of the following: paging cause, busy indication, multi-SIM departure, filtering rules, and paging collision avoidance, the UE can use different values ​​of specified bits to represent the specific Multi-User Identification Card features supported by the UE. For example, when the UE is not in Multi-User Identification Card (Multi-User Identification Card) state, the specified bit is 0; when the UE supports the BUSYindication feature, the specified bit can be 1; when the UE supports the Filtering feature, the specified bit can be 2; when the UE supports the Paging Collision Avoidance feature, the specified bit can be 3; when the UE supports all Multi-User Identification Card (Multi-User Identification Card) features, the specified bit can be 4, etc., and this disclosure does not limit this.

[0077] Step 202: Send first indication information to the access network device. The first indication information is used to determine whether the UE is currently in a multi-user identification card state.

[0078] The specific implementation of the first instruction information and the message type carrying the first instruction information can be referred to in the detailed description of any other embodiment of this disclosure, and will not be repeated here.

[0079] Step 203: Receive second indication information sent by the access network device. The second indication information is used to indicate the multi-user identification card feature information supported by the core network device and / or the access network device.

[0080] The specific implementation of the second instruction information or the message type carrying the second instruction information can be referred to in the detailed description of any other embodiment of this disclosure, and will not be repeated here.

[0081] Step 204: Update the local multi-user identification card feature information according to the second instruction information.

[0082] In this disclosure, in order to facilitate communication and interaction between the UE and the access network equipment and the core network equipment based on the multi-user identification card feature information supported by the access network equipment and the core network equipment, the UE can update its local multi-user identification card feature information after determining the multi-user identification card feature information supported by the access network equipment and / or the core network equipment.

[0083] For example, if the UE supports the BUSYindication feature and determines that the access network device does not support BUSYindication based on the second indication information returned by the access network device, then the UE can disable or delete the local BUSYindication, so that when the service triggers BUSYindication, it will not send BUSYindication to the network.

[0084] Alternatively, if the UE supports the BUSYindication feature, and the access network device and core network device also support BUSYindication based on the second indication information returned by the access network device, then the UE can send BUSYindication to the network when the service triggers BUSYindication.

[0085] In the multi-user identification card feature information interaction method of this disclosure embodiment, the UE only sends first indication information to the access network device to determine whether it is currently in a multi-user identification card state during the multi-user identification card feature information interaction with the network side, thereby saving resources used in the negotiation process.

[0086] Figure 3This is a flowchart illustrating another method for interacting with multi-user identification card feature information provided in an embodiment of this disclosure. This method can be executed by an access network device. Figure 3 As shown, the method for interacting with the multi-user identification card feature information includes the following steps:

[0087] Step 301: Receive first indication information sent by the UE. The first indication information is used to determine whether the UE is currently in a multi-user identification card state.

[0088] Optionally, the aforementioned first indication information may be obtained by the access network device through a specified multi-user identification card characteristic information exchange message, or it may be obtained by parsing other information.

[0089] For example, the access network device can receive the first indication information sent by the UE through a registration request, or it can receive the first indication information sent by the UE through a service request, or it can receive the first indication information sent by the UE through a location update request, etc. This disclosure does not limit this.

[0090] Optionally, the aforementioned multi-user identification card characteristic information includes at least one of the following: paging reason, busy indication, multiple card departure, filtering, and paging conflict avoidance.

[0091] It should be noted that the specific implementation of the first indication information and the specific way in which it represents whether the UE is currently in a multi-user identification card state can be referred to in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0092] Step 302: Send the first instruction information to the core network equipment.

[0093] In this disclosure, the access network device may send the first indication information to the core network device using a specified multi-user identification card characteristic information exchange message, or the first indication information may be carried in the UE's registration request, service request, or location update request. This disclosure does not limit this.

[0094] Optionally, after receiving the first indication information, the access network device can directly forward the information to the core network device.

[0095] Alternatively, the first indication information can be parsed first to determine whether the UE is currently in a multi-user identification card (MIC) state, and the information can be forwarded to the AMF only if it is determined that the UE is currently in a multi-user identification card (MIC) state. This can further reduce the resources required for the UE to negotiate multi-user identification card features with the network side.

[0096] Step 303: Receive second indication information sent by the core network device. The second indication information is used to indicate the multi-user identification card feature information supported by the core network device and / or the access network device.

[0097] Optionally, the access network device may obtain the second indication information returned by the core network device through a specified multi-user identification card characteristic information exchange message, or the second indication information may also be carried in the registration receiving message or service request response message returned by the core network device, which is not limited in this disclosure.

[0098] Step 304: Send the second indication information to the UE.

[0099] In this disclosure, after receiving the second indication information sent by the core network device, the access network device can return the second indication information to the UE using a specified multi-user identification card characteristic information interaction message, or it can carry the second indication information in the registration receiving message or service request response message. This disclosure does not limit this.

[0100] The specific implementation of the second indication information sent by the access network device to the UE, such as the returned message type and the bit value method in the message, can be referred to in the detailed description of any other embodiment of this disclosure, and will not be repeated here.

[0101] The method for exchanging multi-user identification card feature information in this embodiment allows the access network device to send the first indication information sent by the UE to the core network device after obtaining the first indication information sent by the UE, and then send the second indication information returned by the core network device to the UE, thereby saving resources used by the UE and the network side in the process of exchanging multi-user identification card feature information.

[0102] Figure 4 This is a flowchart illustrating a method for interacting with multi-user identification card characteristic information, provided in an embodiment of this disclosure. This method can be executed by a core network device. Figure 4 As shown, the method for interacting with the multi-user identification card feature information includes the following steps:

[0103] Step 401: Receive first indication information sent by the access network device. The first indication information is used to determine whether the user equipment (UE) is currently in a multi-user identification card (MIC) state.

[0104] Optionally, the aforementioned first indication information may be obtained by the core network entity through the interaction message of the specified multi-user identification card characteristic information, or it may be obtained by parsing other information.

[0105] For example, the core network device can parse the registration request sent by the access network device to determine the first indication information, or it can parse the service request sent by the access network device to determine the first indication information, or it can parse the location update request sent by the access network device to determine the first indication information, etc. This disclosure does not limit this.

[0106] Optionally, to reduce the resources consumed when the UE interacts with the network device for multi-user identification card information, in this disclosure, whether the UE is currently in multi-user identification card state can be indicated by the value of a specified bit. For example, when the value of the specified bit is 1, it indicates that the UE is currently in multi-user identification card state.

[0107] Alternatively, since multi-user identification card (Multi-User Identification Card) features may include at least one of the following: paging reason, busy indication, multi-card departure, filtering rules, and paging collision avoidance, the specific Multi-User Identification Card features supported by the UE can be represented by different values ​​of a specified bit. For example, when the UE supports the BUSYindication feature, the specified bit can be 1; when the UE supports the Filtering feature, the specified bit can be 2; when the UE supports the Pagingcollisionavoidance feature, the specified bit can be 3; when the UE supports all Multi-User Identification Card features, the specified bit can be 4, and so on. This disclosure does not limit this.

[0108] Optionally, the specified bit can be a bit in a specified multi-user identification card feature information interaction message, or it can be a bit in a registration request, service request, or location update request.

[0109] Optionally, to further reduce the resources consumed when the UE interacts with network devices for multi-user identification card (Multi-User Identification Card) feature information, in this disclosure, the UE may only include the first indication information in the registration request, service request, or location update request when in Multi-User Identification Card (Multi-User Identification Card) status. When not in Multi-User Identification Card (Multi-User Identification Card) status, the first indication information is not included in the registration request, service request, or location update request. That is, the format of the registration request, service request, or location update request sent by the UE when in Multi-User Identification Card (Multi-User Identification Card) status is different from the format of the registration request, service request, or location update request sent when not in Multi-User Identification Card (Multi-User Identification Card) status.

[0110] It should be noted that the bit specified above can be a single bit or multiple bits, and this disclosure does not limit this.

[0111] The specific implementation of the first indication information and the message type carrying the first indication information can be found in the detailed description of any other embodiment of this disclosure, and will not be repeated here. Step 402: Send second indication information to the access network device. The second indication information is used to indicate the multi-user identification card feature information supported by the core network device and / or the access network device.

[0112] In this disclosure, after receiving the first indication information, the core network device can first determine the multi-user identification card characteristics currently supported by the core network device and the access network device, and generate the second indication information to send the multi-user identification card characteristic information supported by the core network device and / or the access network device to the UE through the access network device.

[0113] Optionally, the core network device may send a second indication message to the access network device based on an interactive message containing specified multi-user identification card characteristic information, or it may send a second indication message to the access network device based on a registration receiving message or a service response message.

[0114] The core network equipment can determine the type or implementation form of the second indication information based on the specific characteristics of the multi-user identification card supported by the core network equipment and / or access network equipment.

[0115] For example, different combinations of user identification card (MIC) feature information correspond to different second indication information. If the core network device determines that both the core network device and the access network device support all MIC feature information, it sends type A second indication information to the access network device; or, if the core network device determines that both the core network device and the access network device support busy indication and filtering rule feature information, it sends type B second indication information to the access network device, and so on.

[0116] Alternatively, different combinations of SIM card feature information correspond to different bit values ​​in interactive messages, registration reception messages, or service response messages. After determining the multi-SIM card feature information supported by the core network equipment and access network equipment, the core network equipment can modify the values ​​of specified bits and then send them to the UE through the access network equipment. This allows the UE to determine the multi-SIM card feature information currently supported by the core network equipment and / or access network equipment based on the values ​​of each bit in the obtained second indication information.

[0117] Alternatively, the core network equipment can also use a similar approach to the UE, using different values ​​of specified bits in interactive messages, registration receive messages, or service response messages to indicate the specific multi-user identification card features supported by the core network equipment and / or access network equipment. For example, when supporting the BUSYindication feature, this bit can be set to 1; when supporting the Filtering feature, this bit can be set to 2; when supporting the Pagingcollisionavoidance feature, this bit can be set to 3, and so on. This disclosure does not limit this.

[0118] The method for exchanging multi-user identification card feature information in this embodiment of the present disclosure, after the core network device receives a first indication message for determining whether the UE is currently in a multi-user identification card state, it sends multi-user identification card feature information supported by the core network device and / or the access network device to the UE through the access network device, thereby reducing the resources occupied when the UE and the network device exchange multi-user identification card feature information.

[0119] Figure 5 This is a flowchart illustrating another method for interacting with multi-user identification card characteristic information provided in an embodiment of this disclosure. This method can be executed by a core network device. Figure 5 As shown, the method for interacting with the multi-user identification card feature information includes the following steps:

[0120] Step 501: Receive first indication information sent by the access network device. The first indication information is used to determine whether the UE is currently in a multi-user identification card state.

[0121] The first indication information may be sent by the UE to the access network device through a registration request, or the first indication information may be sent by the UE to the access network device through a service request, or the first indication information may also be sent by the UE to the access network device through a location service request, or the aforementioned first indication information may also be sent by the UE to the access network device through specified interaction information, and this disclosure does not limit it in this way.

[0122] In a communication network, a UE typically sends a registration request, service request, or location service request to the access network device, which then forwards the received registration request or service request to the core network device.

[0123] Step 502: Determine the multi-user identification card feature information currently supported by the UE based on the value of the specified bit in the first indication information.

[0124] Optionally, in order to reduce the resources occupied when the UE interacts with the network device for multi-user identification card feature information, whether the UE is currently in multi-user identification card state can be indicated by different values ​​of the bits specified in the first indication information.

[0125] For example, when the specified bit is set to 1, it indicates that the UE is currently in a multi-user identification card (MIC) state. Otherwise, the specified bit can be set to 0, or any non-1 value, to indicate that the UE is not currently in a MIC state.

[0126] Alternatively, since multi-user identification card (Multi-User Identification Card) features may include at least one of the following: paging reason, busy indication, multi-card departure, filtering rules, and paging collision avoidance, the specific Multi-User Identification Card features supported by the UE can be represented by different values ​​of specified bits. For example, a specified bit value of 0 indicates that the UE is not in a Multi-User Identification Card state; a specified bit value of 1 indicates that the UE supports the BUSYindication feature; a specified bit value of 2 indicates that the UE supports the Filtering feature; a specified bit value of 3 indicates that the UE supports the Pagingcollisionavoidance feature; a specified bit value of 4 indicates that the UE supports all Multi-User Identification Card features, etc., this disclosure does not limit this.

[0127] Optionally, the specified bit can be a bit in a specified multi-user identification card feature negotiation resource, or it can be a bit in a registration request, service request, or location service request.

[0128] It should be noted that the bit specified above can be a single bit or multiple bits, and this disclosure does not limit this.

[0129] Step 503: Generate second indication information based on the multi-user identification card feature information supported by the core network equipment and / or access network equipment.

[0130] Step 504: Send the second instruction information to the access network device.

[0131] Optionally, in order to further reduce the resources required for the UE to negotiate multi-user identification card (MIC) features with the network, the core network equipment may determine the MIC feature information currently supported by the core network equipment and / or the access network equipment only after determining that the UE is in MIC status, and then return the second indication information to the UE through the access network.

[0132] It should be noted that the specific implementation of the second indication information sent by the core network device to the access network device and the message type carrying the second indication information can be referred to in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0133] The method for exchanging multi-user identification card feature information in this embodiment allows the access network device to send the first indication information sent by the UE to the core network device after obtaining the first indication information sent by the UE, and then send the second indication information returned by the core network device to the UE, thereby saving resources used by the UE and the network side in the process of exchanging multi-user identification card feature information.

[0134] Figure 6 This is a signaling diagram illustrating a method for interacting with multi-user identification card feature information, provided in an embodiment of this disclosure. Figure 6 As shown, the method for interacting with the multi-user identification card feature information includes the following steps:

[0135] Step 601: The UE determines whether it is currently in a multi-user identification card state.

[0136] Optionally, the UE can determine its current multi-user identification card status information based on the current usage or registration status of each user identification card located within it.

[0137] Step 602: The UE determines that it is currently in a multi-user identification card state and sends the first indication information to the access network device.

[0138] Optionally, the UE may send the first indication information to the access network device through a registration request, service request, location service request, or a specified interactive message; this disclosure does not limit this.

[0139] Step 603: The access network device sends the first indication information to the core network device.

[0140] Step 604: The core network device generates second indication information based on the multi-user identification card feature information supported by the core network device and / or the access network device.

[0141] Step 605: The core network device sends a second instruction message to the access network device.

[0142] Step 606: The access network device sends the second indication information to the UE.

[0143] Step 607: The UE updates the local multi-user identification card feature information according to the second instruction information.

[0144] It should be noted that the specific implementation of each of the above steps can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0145] The method for exchanging multi-user identification card feature information in this embodiment allows the UE to send first indication information to the core network device through the access network device after determining that it is in a multi-user identification card state. Then, the core network device can send multi-user identification card feature information supported by the core network device and / or the access network device to the UE through the access network device, thereby saving resources used by the UE in the process of exchanging multi-user identification card feature information with the network side.
