[0087] In this application embodiment, the following problems need to be solved:

[0088] Question 1: In related technologies, the network can indicate the corresponding NW MUSIM capability based on the UE's MUSIM capability. However, the paging restriction (PR) function cannot exist independently; it must be attached to both the leave network and paging denial capabilities. Furthermore, a UE that supports leave network and / or paging denial may not necessarily support paging restriction.

[0089] To address issue 1 above, one solution is as follows: when 1) the UE supports the leave network function and / or paging denial function, and 2) the UE supports the paging restriction function, and the network also supports the paging restriction function, the network instructs the UE to support the paging restriction function. However, when the capabilities 1) and / or 2) change, the network sets the NW PR capability to not support it.

[0090] Question 2: After the CN receives the NAS PR, the CN and RAN still use the release process to reduce the impact on the RAN.

[0091] To address issue 2 above, one solution is for the UE to send a NAS PR to the RAN, and the AMF to send a release indication to the RAN.

[0092] Question 3: After the UE becomes a single SIM card, it can turn off the single or dual SIM mode, or disable all MUSIM capabilities and notify the network. The network will then set the NW MUISIM capability to be unsupported based on the information obtained (only as a defense).

[0093] In one optional embodiment of this application, the MUSIM capability may also be referred to as a first function.

[0159] The information processing method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0160] Please see Figure 2 , Figure 2 This is a flowchart of an information processing method provided in an embodiment of this application. The method is applied to a first communication device, which includes, but is not limited to, a CN network element (such as an AMF). Figure 2 As shown, the method includes the following steps:

[0161] Step 21: If the first condition is met, send information to the terminal indicating support for paging restriction function.

[0162] In this embodiment, the first condition may include at least one of the following:

[0163] The terminal supports paging restriction function;

[0164] The network supports paging restriction functionality.

[0165] In one implementation, if the terminal supports paging restriction functionality and / or the network supports paging restriction functionality, the AMF can send information to the terminal indicating that paging restriction functionality is supported.

[0166] Optionally, the first condition may also include at least one of the following:

[0167] The terminal supports the function of leaving the network;

[0168] The terminal supports paging rejection functionality;

[0169] The network supports the function of leaving the network;

[0170] The network supports paging rejection functionality.

[0171] In one implementation, the terminal can only send paging restriction information to the network when it requests to leave the network or when it sends paging rejection information to the network. Therefore, the paging restriction function needs to be attached to the leave-the-network function or the paging rejection function. It is easy to understand that sending information to the terminal indicating support for the paging restriction function requires considering not only that the terminal and / or the network support the paging restriction function, but also that the terminal and / or the network support the leave-the-network function, or that the terminal and / or the network support the paging rejection function.

[0172] In another implementation, if the terminal supports the leave network function and / or the terminal supports the paging rejection function, and the terminal supports the paging restriction function, the AMF can send information to the terminal to indicate that the paging restriction function is supported.

[0173] In another implementation, if the terminal only supports paging restriction function, the AMF cannot send information to the terminal indicating that paging restriction function is supported.

[0174] It is easy to understand that, through the embodiments of this application, when the first condition is met, the AMF can send information to the terminal to indicate support for the paging restriction function, thereby realizing the indication of support for the paging restriction function.

[0175] Please see Figure 3 , Figure 3 This is a flowchart of an information processing method provided in an embodiment of this application. The method is applied to a second communication device, which includes, but is not limited to, a CN network element (such as an AMF). Figure 3 As shown, the method includes the following steps:

[0176] Step 31: Receive information indicating paging rejection or information indicating a request to leave the network.

[0177] Step 32: Based on the information indicating paging rejection or the information indicating a request to leave the network, send a message to the RAN network element indicating a request to release to a disconnected state.

[0178] In one implementation, the AMF can receive information from the terminal indicating paging rejection or information indicating a request to leave the network. Further, the AMF can receive such information from the terminal via a service request, registration request, or location update request.

[0179] Optionally, the information used to indicate the request to release to a disconnected state may include at least one of the following: information to indicate the request to switch the terminal to a disconnected state, information to indicate the request to set the connection between the terminal and the network to a disconnected state, etc.

[0180] In one implementation, the RAN network element can determine whether to release the terminal into an idle state or an inactive state based on the received information indicating a request to release it into a disconnected state.

[0181] It is easy to understand that, through the embodiments of this application, after receiving information indicating paging rejection, the AMF can send information to the RAN network element indicating the setting of a disconnected state, thereby solving the problem of connection release between the terminal and the network.

[0182] Please see Figure 4 , Figure 4 This is a flowchart of an information processing method provided in an embodiment of this application. The method is applied to a third communication device, which includes, but is not limited to, a CN network element (such as an AMF). Figure 4 As shown, the method includes the following steps:

[0183] Step 41: Obtain the first information.

[0184] Step 42: Based on the first information, perform the first operation.

[0185] Optionally, the first operation may include at least one of the following:

[0186] Send a message indicating that the second function is not supported;

[0187] Send an indication message to indicate why the paging reason should not be sent.

[0188] Optionally, the first information may be used to indicate at least one of the following: the terminal enters single-SIM mode, the terminal exits multi-SIM mode, the terminal does not support the first function, or the terminal does not request or need the first function.

[0189] Optionally, the first function may include at least one of the following: paging rejection function, paging restriction function, paging reason function, leaving the network function, paging conflict avoidance function, etc.

[0190] Optionally, the second function may include at least one of the following: paging rejection function, paging restriction function, paging reason function, leaving the network function, and avoiding paging conflicts function.

[0191] The second function may be the same as or different from the first function.

[0192] In one implementation, the AMF can receive first information from the UE.

[0193] In one implementation, the function of leaving the network includes at least one of the following: releasing the terminal from the network connection, and configuring the terminal to a disconnected state.

[0194] Optionally, sending the information to indicate that the second function is not supported may include: sending information to indicate that the network does not support the second function.

[0195] Optionally, sending the information to indicate that the second function is not supported may include: sending information to the terminal and / or RAN network element to indicate that the second function is not supported.

[0196] Optionally, sending the indication information for not sending a paging reason may include: sending the indication information for not sending a paging reason to the RAN network element.

[0197] In one implementation, upon receiving the first information, the RAN network element sends either information indicating that the first function is not supported or an indication indicating that a paging reason should not be sent. It is easy to understand that for an inactive terminal, the RAN network element may choose not to send a paging reason to the terminal based on the received information.

[0198] Optionally, the sending of information indicating that the second function is not supported includes at least one of the following:

[0199] If the first information indicates that the terminal does not support the first function, and the first function includes at least one of the paging reason function and the paging rejection function, then information indicating that the second function is not supported is sent, and the second function includes the paging reason function.

[0200] If the terminal does not support the first function indicated by the first information, and the first function includes at least one of paging rejection function, paging restriction function, and network exit function, then information indicating that the second function is not supported is sent, and the second function includes paging restriction function.

[0201] It is easy to understand that, through the embodiments of this application, after receiving the first information, the AMF can send information to the terminal to indicate that the second function is not supported, thereby realizing the indication that the first function is not supported.

[0202] Please see Figure 5 , Figure 5 This is a flowchart of an information processing method provided in an embodiment of this application. The method is applied to a fourth communication device, which includes, but is not limited to, a terminal. Figure 5 As shown, the method includes the following steps:

[0203] Step 51: If the second condition is met, perform the second operation.

[0204] Optionally, the second operation may include at least one of the following:

[0205] Set the first function to not support;

[0206] Set the multi-SIM mode to single-SIM mode, or exit multi-SIM mode;

[0207] Set the first information; for example, you can set the first information to indicate that the terminal does not support the first function.

[0208] Send the first message.

[0209] The first information may be used to indicate at least one of the following: the terminal enters single-card mode, the terminal exits multi-card mode, the terminal does not support the first function, or the terminal does not request or need the first function.

[0210] The first function may include at least one of the following: paging rejection function, paging restriction function, paging reason function, leaving network function, and paging conflict avoidance function.

[0211] Optionally, the second condition may include at least one of the following:

[0212] The terminal enters single-SIM mode;

[0213] The terminal exits multi-SIM mode;

[0214] The terminal does not request or require the primary function.

[0215] In one implementation, even if the terminal supports the first function, the terminal still sends the first information if the second condition is met, such as the first information indicating that the terminal does not support the first function.

[0216] It is easy to understand that, through the embodiments of this application, an indication that the first function is not supported can be achieved.

[0217] The embodiments of this application will be described below in conjunction with specific application scenarios.

[0218] Example 1

[0219] In Embodiment 1 of this application, as Figure 6 As shown, the instruction process for paging restriction function may include the following steps:

[0220] Step 61: The UE in Radio Resource Control (RRC) connected state sends a registration request to the serving AMF. This registration request may include: the terminal supports paging rejection and paging restriction; or, the registration request may include: the terminal supports leaving the network and paging restriction.

[0221] Step 62: The serving AMF sends a registration response to the UE. This registration response may include information indicating support for paging restriction functionality.

[0222] For example, the registration response includes information indicating that the network supports the NW Paging Restriction Capability.

[0223] Example 2

[0224] In Embodiment 2 of this application, as Figure 7 As shown, the process of releasing a connection may include the following steps:

[0225] Step 71: The UE in RRC connected state sends a service request to the serving AMF, which may include information indicating paging rejection.

[0226] Step 72: The serving AMF sends a UE context modification request to the NG-RAN. The UE context modification request may include paging restriction (PR), information for indicating the setting of a disconnected state (such as release indication), etc.

[0227] Step 73: NG-RAN sends a UE context modification response to the serving AMF.

[0228] Step 74: Release the RRC connection between the UE and the network.

[0229] Step 75: NG-RAN sends UE context release information to the serving AMF.

[0230] Step 76: Release RRC based on the RRC inactive state configuration.

[0231] Step 77: In the RRC inactive state, use PR to restrict paging.
