Abstract

A user equipment UE attaches to a first network, and displays a first network name, where the first network name is a network name of the first network; or the UE executes a combined attach procedure or a combined tracking area update procedure to attach to the first network or a second network, and displays the first network name, where the first network name is a network name of the first network or a network name of the second network; and in a process of executing a service in the first network, the UE changes from the first network to the second network or a third network, and the UE keeps displaying the first network name. It is ensured that a network name displayed on a terminal is consistent with a network name that is displayed on a UE and recorded by a network device.
