The following description describes a new air interface (NR) system for purposes of example, and in much of the description that follows, NR terminology is used, these techniques may also be applied to applications other than NR system applications, such as the 6th generation (6th Generation,6G) communication system.

Fig. 1 shows a block diagram of a wireless communication system to which an embodiment of the present application is applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a terminal device or a User Equipment (UE), and the terminal 11 may be a terminal-side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop (laptop computer) or a personal digital assistant (personal DIGITAL ASSISTANT, PDA), a palm computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile internet device (mobile INTERNET DEVICE, MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), and the wearable device includes: smart watches, bracelets, headphones, eyeglasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

For ease of understanding, some of the following descriptions are directed to embodiments of the present application:

For independent (standalone, SA) 5G networks that rely solely on evolved packet system (evolved PACKET SYSTEM, EPS) fallback for IP multimedia system (IP Multimedia Subsystem, IMS) voice services, all IMS voice calls in the 5G system will fail because the SA 5G network cannot support NR based voice services (VoNR) and if the terminal disables its evolved universal terrestrial radio access (Evolved Universal Terrestrial Radio Access, E-UTRA) functionality if it is transferred to the 5G system, EPS fallback cannot be performed due to the E-UTRA functionality of the terminal being disabled.

The situation becomes worse because the terminal does not know the cause of the failure. The terminal may reattempt to initiate an IMS voice call in the current network while still maintaining its E-UTRA functionality disabled. Thereby causing additional invalid signaling overhead, resulting in resource waste.

The communication processing method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a communication processing method according to an embodiment of the present application, as shown in fig. 2, including the following steps:

Step 201, a terminal sends a first registration request message to a network side device located in a first network, wherein the first registration request message comprises service information and information that the terminal does not support a second network;

In the embodiment of the present application, the first registration request message is a registration request message sent in a process that the terminal registers the first network. The network side device may allow the terminal to register based on the first registration request message, thereby providing the network service for the terminal. In the communication system, if the terminal supports the second network, the network side device may enable the terminal to fall back from the first network to the second network based on the fall-back procedure, and provide a service function of the service that is not supported by the first network through the second network. For example, in some embodiments, the first network may be a fifth generation mobile communication (5G) network, and the second network may be a fourth generation mobile communication (4G) network, although in other embodiments, other network types are also possible, which is not limited herein.

Step 202, the terminal receives first information sent by the first network based on the first registration request message, where the first information includes first indication information, where the first indication information is used to indicate that a reason why the first service cannot be provided is: the terminal does not support the second network, so that the terminal cannot fall back to the second network; the first information is carried on a configuration update command, a fifth generation mobile communication mobility management state (5G Mobility Management Status,5GMM STATUS) message, or radio resource control (Radio Resource Control, RRC) signaling.

In the embodiment of the present application, for example, taking 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 an SA 5G network, and the terminal is assumed to reside in the SA 5G network, because the SA 5G network cannot support the NR-based voice service (VoNR), the terminal can only provide the voice service for the terminal by falling back to the 4G network through EPS Fallback (Fallback), and because the communication module of the 4G network of the terminal is disabled, the terminal cannot acquire the voice service. At this time, the network side device may notify the terminal of the reason why the first service cannot be provided by transmitting the first information based on the registration information of the terminal. In this way, the terminal may not initiate the first service request for this reason, or in case of failure of the first service request, may not initiate the first service request again, and the latter opens the communication function of the second network, so that the network side device may implement rollback and provide the service function of the first service.

Optionally, the first information is carried in the configuration update command, which is understood that the network side device sends the first information through a configuration update procedure (Generic UE configuration update procedure) of the terminal. The first information is carried in the fifth generation mobile communication mobility management STATUS message, which can be understood that the network side device sends the first information through the 5GMM STATUS procedure. The first information is carried in RRC signaling, which may be understood that the network side device may send the first information through an RRC signaling procedure, and specifically, the terminal may obtain the first information through a procedure of obtaining system information, RRC establishment, RRC reconfiguration, RRC release, and the like. The embodiment of the application sends a first registration request message to network side equipment positioned in a first network through a terminal, wherein the first registration request message comprises service information and information that the terminal does not support a second network; the terminal receives first information sent by the first network based on the first registration request message, wherein the first information comprises first indication information, and the first indication information is used for indicating that a first service cannot be provided because: the terminal does not support the second network, so that the terminal cannot fall back to the second network; the first information is carried on a configuration update command, a fifth generation mobile communication mobility management status message or radio resource control RRC signaling. In this way, the terminal may not initiate the first service request for this reason, or in case of failure of the first service request, may not initiate the first service request again, and the latter opens the communication function of the second network, so that the network side device may implement rollback and provide the service function of the first service. Therefore, the embodiment of the application improves the reliability of communication.

It should be understood that in the embodiment of the present application, the first information may be carried by adding a cell (Information Element, IE) to the signaling message, or the first information may be carried in an existing cell, for example, the first information may be carried by a 5GMM cause (cause) cell. Specifically, the reason why the terminal cannot provide the first service may be indicated by carrying the first information through a Cause value (Cause value) is: and the terminal does not support the second network, so that the terminal cannot fall back to the second network.

Optionally, in some embodiments, the first information includes: the second indication information is used for indicating that the first network cannot provide the first service, and the second network can provide the first service.

In other words, in the embodiment of the present application, the network side device may instruct the terminal to open the fourth-generation mobile communication capability by instructing to open the fourth-generation mobile communication capability, open the S1 mode capability, enable the S1 mode function, or restart the evolved universal terrestrial radio access function. Optionally, the network side device may instruct, through one or more bits, whether the terminal opens the communication module of the second network. For example, in some embodiments, the network side device may instruct the terminal to not open the communication module of the second network through 0 and instruct the terminal to open the communication module of the second network through 1.

It should be understood that in the embodiment of the present application, the S1 mode may be understood as: an evolved packet-switched core network (Evolved Package Core Network, EPC) non-access stratum (NAS) that, in case the terminal does not support the S1 mode, the terminal does not support the second network. Wherein, not supporting the S1 mode can be understood as not supporting EPC NAS.

Optionally, in some embodiments, the feedback information is indication information carried by a notification message for updating the capability of the terminal, or the feedback information is information carried by a second registration request message, where the second registration request message is a registration request message sent after the terminal opens a communication module of the second network.

And if the network side equipment adopts the configuration updating command to send the first information to the terminal, the terminal can send the feedback information through the configuration updating completion message, or can send the feedback information through the second registration request message after the terminal opens the communication module of the second network. The terminal re-registers with the first network through a second registration request message, where the second registration request message may only carry the feedback information, and may also include other registration information besides the feedback information.

In the embodiment of the application, when the capability information of the terminal supporting the second network is fed back through the second registration request message, a new signaling design is not required to be added, thereby reducing the difficulty of the design of the communication system. When the capability information of the second network is fed back to the terminal through the notification message, other signaling processing flows can be avoided from being introduced, and the complexity of the design of the communication system is reduced.

The terminal may send a second registration request message after opening the communication module of the second network. The second registration request message includes a feedback message for indicating that the terminal supports the second network. At this time, when the terminal requests the first service, the network side device may roll back to the second network through the roll-back process to provide the first service for the terminal, where the first service may be understood as a service corresponding to the first service.
