AI Technical Summary
Technical Problem
During disaster roaming, existing technologies struggle to effectively manage 5G mobility management state transitions, resulting in user devices being unable to register stably and switch networks in disaster situations.
Method used
During the disaster roaming wait period, the user equipment starts a timer with a randomly generated value to enter a specific 5G mobility management state, avoiding state transitions for non-emergency services until the disaster situation ends.
Benefits of technology
It improves the stability and switching efficiency of user equipment network registration in disaster situations, ensuring that normal network connectivity can be quickly restored after the disaster ends.

Abstract
According to one aspect of the present disclosure, a method, a computer readable medium, and an apparatus are provided. The device may be a user device. The user equipment selects a network for disaster roaming. The user equipment starts a timer with a randomly generated value within a disaster roaming waiting range. When the user equipment is in a logout state, the user equipment enters a 5G mobility management-logout state when the timer runs, and attempts to be in a registration (5GMM-DEREGISTERED.ATTEMPTNG-REGISTRATION) state. When the user equipment is in a registration state, the user equipment enters a 5G mobility management-registration state when the timer runs, and a registration update (5GMM-REGISTERED.ATTEMPTNG-REGISTRATION-UPDATE) state is attempted. While the timer is running, the user equipment avoids starting any 5G mobility hypervisor in addition to emergency services.
