Description

Terminal registration method, terminal and network side equipment

Technical Field

The application belongs to the technical field of wireless communication, and particularly relates to a terminal registration method, a terminal and network side equipment.

Background

When a Public Land Mobile Network (PLMN) disaster (e.g., fire) occurs, the PLMN may not be able to provide service for a User Equipment (UE) continuously. To reduce the impact on the UE, if there are other PLMNs ready to provide service (e.g., voice calls and/or mobile data services, etc.) for the UE, the UE may obtain service from the other PLMNs in the event of a disaster, such that service disruption is minimized.

In a non-disaster scenario (i.e. a scenario where the serving PLMN of the UE cannot provide services to the terminal due to a disaster), the UE is not allowed to access to a forbidden (forbidden) PLMN. However, in order to avoid that the UE cannot obtain the service in a disaster scenario and improve the service experience of the user, especially for the UE with emergency service forwarding, the 3GPP system needs to provide a technical solution for minimizing the service interruption of the UE by registering to the forbidden PLMN of the UE. However, the precondition for accessing to the forbidden PLMN is: the serving PLMN of the UE is DC-enabled and the UE cannot find an allowed (allowed) PLMN.

But for the following scenario:

PLMN A is the forbidden PLMN of the UE, but has not yet been added to the forbidden PLMN list of the UE;

DC generation of PLMN D serving the UE;

PLMN a is able to provide DC service to PLMN D in the event of DC.

Because the PLMN a is not yet added to the forbidden PLMN list of the UE, the UE may regard the PLMN a as an allowed PLMN of the UE, and perform selection and registration, and the UE may not carry any registration information related to the DC scenario when registering to the PLMN a.

For this situation, the PLMN a processing manner is to reject the registration request of the UE (because the PLMN a is a forbidden PLMN of the UE), and then the UE needs to add the PLMN a to the forbidden PLMN list of the UE, and further needs to perform PLMN a selection and registration in the DC scenario, which obviously increases signaling overhead of the UE and the PLMN a.
