Embodiments of the present application disclose a fault alarm method, device and electronic equipment. The method comprises the following steps: a network detection end sends network fault information to a plurality of public land mobile networks (PLMNs) through a network; the PLMNs forward the network fault information to a shared base station; and when the shared base station detects that the network fault information forwarded by a fault PLMN is not received, it is indicated that a terminal corresponding to the fault PLMN cannot learn that the fault PLMN has entered a disaster situation, therefore, the network fault information is broadcast to the terminal corresponding to the fault PLMN, so that the terminal can quickly identify a communication service problem, reduce a terminal network service interruption time, and improve user experience.

A user equipment (UE) can receive a list of public land mobile networks (PLMNs) that support a given network slice in a given country, which is different from a home country of a home PLMN of the UE. When roaming in the given country, the UE can access a PLMN in the list if the given network slice is desired. The list can be provided by the home PLMN when the UE is in the home country; or the list can be provided via a visited PLMN when the UE is in the given country. The list can be received in response to a UE-initiated request, or pushed to the UE by the home PLMN. A validity timer period received with the list can indicate a duration of validity of the list. In an alternative scenario, the UE can receive the list from an authority server, e.g., an authority server belonging to a visited PLMN.

The terminal device sets the first information based on the registration response. The first information indicates a selection policy that is determined by the core network element and that is of selecting a closed access group (CAG) by the terminal device when the terminal device accesses a first PLMN, and the second information indicates a selection policy that is determined by the core network element and that is of selecting a CAG by the terminal device when the terminal device accesses the first PLMN.
