The above request message may include at least one of the following: information indicating that the first service is the center, and information indicating that the terminal cannot support the second network.

Optionally, the first service may include, but is not limited to, a voice service and the like.

Optionally, the first network cannot support the first service, and the second network supports the first service. For example, the first network is a 5G network, a 6G network, etc., and the second network is a 4G network, etc., but this embodiment does not specifically limit the first network and the second network.

It should be pointed out that for the terminal that cannot support the second network, it may be a communication module that supports the second network on the terminal hardware, but for some reasons, the terminal disables the communication module of the second network for a period of time, so the terminal cannot support the second network. network. Taking the second network as a 4G network as an example, the terminal may disable the S1 mode capability (disable S1 mode capability) for a period of time due to some reasons, that is, disable the communication module of the 4G network in the terminal for a period of time. For example, if the terminal is in a garage, but there is no 4G network coverage in the garage, after the terminal fails to perform Tracking Area Update (TAU) for a preset number of times, such as 5 times, the terminal can disable the communication module of the 4G network for a period of time. For example, disable it for 12 minutes.

Step 22: The terminal receives the request response message from the network side device.

Optionally, the above request response message may include a cause value, where the cause value is used to indicate that the terminal cannot fall back to the second network to obtain the first service because the terminal does not have the capability to support the second network.

For example, take the first network as a 5G network, the second network as a 4G network, and the first service as a voice service as an example, the 5G network is a standalone (SA) 5G network, assuming that the terminal resides on the SA 5G network, because SA 5G network cannot support NR-based voice services (Voice Over New Radio, VoNR), and can only fallback (Fallback) through Evolved Packet System (EPS) to fall back to 4G network to provide voice services for terminals. If the communication module of the 4G network is disabled, the terminal will not be able to obtain voice services.

In the information processing method of the embodiment of the present application, after the terminal sends a request message to the network-side device located in the first network, if the request message includes information indicating that the first service is the center and/or indicates that the terminal cannot support the second network information, a request response message including a cause value can be received from the network side device, where the cause value is used to indicate that the terminal cannot fall back to the second network to obtain the first service because the terminal does not have the ability to support the second network. In this way, through the reason value, the terminal can be informed of the reason why the first service cannot be obtained, thereby avoiding affecting the terminal's residency in the first network, thereby ensuring that the terminal resides in the first network that initiates the request, and at the same time enjoys the services provided by the first network. Services to ensure user experience.

Optionally, the above-mentioned request message may include but is not limited to: a registration request message, a routing update request message, etc.; correspondingly, the above-mentioned request response message may include but not limited to: a registration request rejection message, a routing update request rejection message, a registration request Accept messages, route update request accept messages, etc.

Optionally, the above-mentioned reason value can also be used to indicate that the first network cannot provide the service of the first service, and that the second network can provide the service of the first service, so that the terminal learns that the first network cannot provide the service of the first service and the second network cannot provide the service of the first service. The second network can provide the service of the first business.

Optionally, the above-mentioned reason value can also be used to instruct the terminal to turn on the communication module supporting the second network, and perform the request operation in the first network again, so that the terminal can re-enter the first network in the case of supporting the second network. Perform the requested operation.

Optionally, the above-mentioned reason value may also be used to instruct the terminal not to reselect to the third network, so as to prevent the terminal from being unable to camp on the first network after reselecting to the third network. For example, the third network is a 2G network and/or a 3G network.

Optionally, after receiving the request response message from the network side device, the terminal may turn on a communication module supporting the second network, and perform the request operation in the first network again. For example, when re-executing the request operation in the first network, the terminal may send a request message to the network-side device, where the request message includes information indicating that the first service is the center and/or information indicating that the terminal supports the second network, And receive a request accept message from the network side device.

Please refer to FIG. 3. FIG. 3 is a flowchart of an information processing method provided by an embodiment of the present application. The method is executed by a network side device, such as a 5G core (5G Core, 5GC) network element, including but Not limited to AMF and the like. As shown in Figure 3, the method includes the following steps:

Step 31: The network side device receives the request message from the terminal.

It should be pointed out that for the terminal that cannot support the second network, it may be a communication module that supports the second network on the terminal hardware, but for some reasons, the terminal disables the communication module of the second network for a period of time, so the terminal cannot support the second network. network.

Step 32: The network side device sends a request response message to the terminal.

In the information processing method of the embodiment of the present application, after receiving the request message from the terminal, if the request message includes information indicating that the first service is the center and/or information indicating that the terminal cannot support the second network, it can A request response message including a cause value is sent to the terminal, where the cause value is used to indicate that the terminal cannot fall back to the second network to obtain the first service because the terminal does not have the capability to support the second network. In this way, through the reason value, the terminal can be informed of the reason why the first service cannot be obtained, thereby avoiding affecting the terminal's residency in the first network, thereby ensuring that the terminal resides in the first network that initiates the request, and at the same time enjoys the services provided by the first network.

Step 41: The UE sends a registration request message to the AMF located in the 5G network, and the registration request message includes at least one of the following: information indicating that the voice service is the terminal (such as voice priority mode voice centric information), indicating that the UE does not support the 4G network. information. The fact that the UE does not support the 4G network can be understood as the fact that the UE does not have the ability to support the Evolved Packet Core (EPC) non-access stratum (Non-Access Stratum, NAS), and the UE does not have the ability to support S1mode. The reason why the UE does not support the 4G network is that the communication module of the 4G network in the UE is disabled.

Step 42: Since the 5G network cannot support the voice service, the 4G network supports the voice service, but the communication module of the 4G network in the UE is disabled, the AMF can reject the registration request message and send the registration request rejection message to the UE. The registration request rejection message may include a cause value, such as a 5G mobility management cause (5GMM cause), etc., to indicate that the UE cannot fall back through the Evolved Packet System because the UE does not have the capability of the 4G network (such as the S1mode capability). System Fall Back, EPS FB) to the 4G network to obtain voice services, that is, the 4G network cannot provide voice services for the UE, and the above EPS FB can also be called ESP fallback.

Optionally, the above reason value can also be used to indicate that the 5G network cannot provide the service of the first service, and the 4G network can provide the service of the voice service, so that the terminal can know that the 5G network cannot provide the service of the first service and the 4G network can provide the voice service. business services.

Optionally, the above reason value can also be used to instruct the UE to turn on the communication module of the 4G network, and re-execute the request operation on the 5G network, so that the terminal can re-initiate the registration process on the 5G network and register to the 5G in the case of supporting the 4G network. network.

Optionally, the above-mentioned reason value can also be used to instruct the UE not to reselect to the 2G network and/or 3G network, so as to prevent the terminal from being unable to camp on the 5G network after reselecting to the 2G network and/or 3G network.

Step 43: After receiving the registration request rejection message, the UE does not reselect to the 2G network and/or the 3G network, but turns on the communication module of the 4G network, and re-initiates the registration process on the 5G network to register with the 5G network, thereby It is guaranteed that the UE resides on the 5G network, while enjoying the data services and voice services of the 5G network, ensuring user experience and improving the resident ratio of the 5G network. Among them, the UE opening the communication module of the 4G network can be understood as the ability of the UE to reactivate the 4G network, or the ability to open the S1mode, or re-enable the evolved Universal Terrestrial Radio Access (Evolved Universal Terrestrial Radio Access, E-UTRA).
