step S10, when registering the 5G network, if the network does not support the VoNR and EPS fallback, after the network refuses to register the 5G network, initiating 4G network registration in LTE.
Specifically, when the terminal is registering in the 5G network, if the network does not support the VoNR and EPS fallback, the network initiates 4G network registration in LTE after the network refuses to register in the 5G network, so as to ensure availability of the mobile phone voice service.
As shown in fig. 3, which is a flowchart of step S10 in the preferred embodiment of the method for registering a terminal in a 5G ad hoc network of the present invention, the step S10 includes:
step S11, when registering the 5G network, initiating the request of 5G network registration to carry identification information so as to judge whether the network end supports VoNR and EPS fallback;
step S12, if the network does not support the VoNR and EPS fallback, rejecting to register the 5G network, and then continuing to initiate the 4G registration request in the LTE.
Specifically, when accessing the 5G network, the terminal carries the terminal capability in a registration request (initiating a registration request of the 5G network) to notify the network terminal whether to support VoNR and EPS fallback; if the network does not support the VoNR and EPS fallback, because the terminal takes the voice service as the priority at present, the voice service is higher than the data service, and the terminal does not support the VoNR and EPS fallback, which indicates that the terminal cannot use the voice service, at this time, in order to ensure the availability of the mobile phone voice service, the network will refuse to perform 5G network registration, and then continue to initiate an Attach request (4G registration request) in LTE, so that the terminal resides in 4G, 3G, or 2G.
The Attach request may also be a TAU (Tracking Area Update, which is a location Update performed by the LTE terminal in the LTE network) request; the TAU and the Attach are both registration requests on the 4G network, are used for different scenarios, and the terminal can register on the 4G network through both of them.
The Attach refers to general registration, and the TAU refers to network configuration parameters that after the TAU registers for a period of time, when the mobile phone detects that a Tracking Area (Tracking Area) of a currently residing network is different from a Tracking Area stored in the mobile phone, the mobile phone synchronizes to a new network through a TAU flow.
Further, when registering the 5G network, the request for initiating the 5G network registration carries identification information to determine whether the network supports VoNR and EPS fallback, and then the method further includes:
and if the network side supports VoNR and EPS fallback, allowing 5G network registration.
Specifically, when registering the 5G network, the network terminal is notified whether to support the VoNR and the EPS fallback, and if the network terminal supports the VoNR and the EPS fallback, which indicates that the terminal can use the voice service, the 5G network registration is allowed.
Step S20, when initiating data service, re-initiating a 5G network registration request to the network terminal, wherein the registration request carries priority information, and initiating a PDN connection to the network terminal.
Specifically, when the terminal is performing data service, a 5G network registration request is reinitiated to the network, and the registration request carries priority information, and a PDN connection establishment request is initiated to the network.
Further, fig. 4 is a flowchart of step S20 in the 5G independent networking terminal registration method provided by the present invention.

Specifically, after the terminal fails to register in the 5G network, when the terminal performs a PS domain service (data service, such as internet access, etc.), the terminal re-initiates a 5G network registration request to the network, in the process of initiating the 5G network registration request, UE's usage setting (the UE's usage setting is used for appointing the priority of the terminal for supporting the Voice service and the Data service, two values are provided, namely, Voice central and Data central, the Voice central indicates that the priority of the Voice service of the terminal is higher than that of the Data service, the Data central indicates that the priority of the Data service of the terminal is higher than that of the Voice service) is carried, the priority information of the Data service of the terminal which is higher than that of the Voice service is sent to the network terminal, and initiating PDN connection to a network terminal, wherein the PDN connection is IP connection between the terminal and an EPC network, and the terminal requests to establish a new PDN connection through a PDN connection flow so as to perform different services with the network.
Further, when registering the 5G network, if the network does not support the VoNR and the EPS fallback, after the network refuses to register the 5G network, initiating 4G network registration in LTE, and then further including:
when the 5G network registration request is reinitiated, if priority information used for indicating that the priority of the voice service is higher than that of the data service is sent to the network terminal, the 5G network registration fails.
Specifically, when the 5G network registration request is reinitiated, if the terminal with the UE's use setting has priority higher than priority information of the data service, and sends the priority information to the network, the network will reject registration of the 5G network.
Step S30, after the data service is finished, re-initiating the 4G network registration request in LTE, and switching the 5G network to the 4G network for voice service.
Specifically, after the data service performed by the terminal is finished, the 4G network registration request is initiated in LTE again, and the 5G network is switched to the 4G network, so as to ensure normal operation of the voice service.
Further, fig. 5 is a flowchart of step S30 in the 5G independent networking terminal registration method provided by the present invention.
As shown in fig. 5, the step S30 includes:
step S31, when the data service is finished, the voice service is carried out to switch the 5G network to the 4G network;
step S32, in the process of network handover, re-initiate the 4G network registration request in LTE to control the voice service to proceed normally.
Specifically, after the data service performed by the terminal is finished, since the terminal is centered on the voice service, in order to satisfy the voice service, when there is no data service, the terminal switches the 5G network to the 4G network, and in the process of network switching, the 4G network registration request is initiated in LTE again to control the normal operation of the voice service.
Further, in step S30, after the data service is ended, re-initiating the 4G network registration request in LTE, and switching the 5G network to the 4G network for the voice service, the method further includes:
and if the data service is initiated again, continuing to initiate the 5G network registration request.
Specifically, after the data service is finished, the 4G network registration request is initiated again in the LTE, and during the process of switching the 5G network to the 4G network for the voice service, if the data service is initiated again, the terminal will continue to initiate the 5G network registration request.
Further, as shown in fig. 6, fig. 6 is an overall schematic diagram of a preferred embodiment of the registration method of the 5G independent networking terminal of the present invention, and the overall schematic diagram is as follows: after the terminal fails to register in the 5G network, when the terminal performs PS domain services (Data services, such as internet access and the like), the terminal re-initiates a 5G network registration request to the network terminal, if UE's use setting is carried in the process of initiating the 5G network registration request, the UE's use setting is used for specifying the priority of the terminal for supporting Voice services and Data services, and two values, namely, Voice center and Data center are provided, the Voice center indicates that the Voice service priority of the terminal is higher than the Data services, the Data center indicates that the Data service priority of the terminal is higher than the Voice services), the Voice service priority of the terminal is higher than the Voice center priority of the Data services, the network terminal rejects the 5G registration of the terminal, at this time, in order to ensure the availability of the mobile phone Voice services, the network terminal rejects the 5G network registration, and then continues to initiate a 4G registration request in LTE, and the terminal is allowed to reside on 4G, 3G or 2G so as to ensure the normal operation of the voice service.
After the terminal fails to register in the 5G network, when the terminal performs a PS domain service (data service, such as internet access, etc.), the terminal re-initiates a 5G network registration request to the network, if the 5G network registration request is initiated and carried with UE's usage setting (the UE's usage setting is used for appointing the priority of the terminal for supporting the Voice service and the Data service, two values are provided, namely, Voice central and Data central, the Voice central indicates that the priority of the Voice service of the terminal is higher than that of the Data service, the Data central indicates that the priority of the Data service of the terminal is higher than that of the Voice service), the Data central priority information of which the priority is higher than that of the Voice service is sent to the network terminal, initiating PDN connection to a network terminal, wherein the PDN connection is IP connection between the terminal and an EPC network, and the terminal requests to establish a new PDN connection through a PDN connection flow so as to perform different services with the network; after the data service performed by the terminal is finished, because the terminal is centered on the voice service, in order to meet the voice service, when no data service exists, the terminal switches the 5G network to the 4G network, and in the process of network switching, a 4G network registration request is initiated in LTE again to control the normal operation of the voice service.
According to the invention, after the 5G independent networking of the terminal is refused by the 5G network, when a data service exists, the terminal retries to initiate the registration request on the 5G network, so that the problems that the 5G network of the terminal is refused and can only reside in the 4G network, a user can not reside in the 5G network, the 5G data service can not be obtained, and the 5G high-speed Internet access can not be enjoyed are solved, and the terminal can be preferentially accessed into the 5G NR network, so that the terminal can be ensured to use the data service of the 5G network.
