Abstract: The present invention discloses a method, a device, and a system for returning to an LTE network. The method of the present invention includes: after a CSFB service of a UE ends, receiving, by a base station, a PLMN ID of an LTE network with which the UE registers, where the PLMN ID is sent by a serving MSC/VLR of the UE; determining LTE frequency band information according to the PLMN ID; and sending, to the UE, a connection release message that includes the LTE frequency band information, so that the UE returns to an LTE PLMN corresponding to a PLMN ID with which the UE previously registers, thereby ensuring continuity of a PS service, avoiding an unnecessary inter-PLMN handover.

Abstract: A method and an apparatus for displaying a network name are provided. By using a combined attach procedure or a combined tracking area update procedure, a user equipment UE registers with a long term evolution network and a first circuit switched domain network, and acquires a public land mobile network identity PLMN ID of the long term evolution network and a PLMN ID of the circuit switched domain network. The UE displays a first network name corresponding to a predetermined PLMN ID before a to-be-displayed second network name sent by a first network device on the long term evolution network is received. The predetermined PLMN ID is one of the PLMN ID of the long term evolution network and the PLMN ID of the circuit switched domain network.
