Abstract

Embodiments of this application disclose an information maintenance control method and user equipment. The user equipment starts at least one timer, where the at least one timer is used to indicate forbidden duration of an area in which the user equipment receives a non-integrity protected reject message during registration. The user equipment deletes information about a first area in a target forbidden list and retains information about a second area in the target forbidden list if the at least one timer expires. The first area is the area in which the user equipment receives the non-integrity protected reject message during registration, and the second area is an area in which the user equipment receives an integrity protected reject message during registration.
