Abstract
The present invention relates to the field of communications technologies and discloses a method for selecting an LTE network and a device, so as to ensure continuity of a PS service, avoid unnecessary inter-PLMN handover, and improve user experience. The method mainly includes: acquiring, by an MSC/VLR, an identity of an LTE PLMN in which UE is registered, where the MSC/VLR is an MSC/VLR after the UE falls back to a 2G/3G network because of performing a CS service; and sending, by the MSC/VLR, a notification message to the UE, where the notification message includes the identity of the LTE PLMN, which is used to indicate the LTE PLMN that the UE returns to, and the LTE PLMN is used as a registered PLMN in the 2G/3G network. Embodiments of the present invention are mainly used in a process of fallback to an LTE network after a CSFB service ends.
