METHOD AND SYSTEM FOR RETURNING TO LONG TERM EVOLUTION NETWORK AND MOBILE SWITCHING CENTER

摘要

Embodiments of the present invention disclose a method, a mobile switching center and a system for returning to a long term evolution network, which may prevent a UE which does not need to return to the LTE network from mistakenly returning to the LTE network. The method includes: receiving a first CSFB indication corresponding to a UE that is sent by a MME after the UE initiates CSFB, wherein the first CSFB indication is used for identifying that the UE needs to return to a LTE network after circuit service of the UE is finished; and sending, according to the first CSFB indication, a second CSFB indication corresponding to the UE to an RNC/BSC when the circuit service of the UE is finished, wherein the second CSFB indication is used for indicating that the RNC/BSC is to notify the UE of returning to the LTE network.

1. A method for returning to a long term evolution network, comprising:
initiating, by the user equipment (UE), a circuit service fall back (CSFB) to a mobility management entity (MME) for sending a first CSFB indication corresponding to a user equipment (UE), wherein the first CSFB indication is used for identifying that the UE needs to return to a long term evolution (LTE) network after circuit service of the UE is finished; and when the circuit service of the UE is finished, receiving, by the UE, a notify the UE of returning to the LTE network from a radio network controller (RNC)/base station controller (BSC) corresponding to the UE, wherein the notify is sent by the RNC/BSC after received a second CSFB indication, wherein the second CSFB indication is used for indicating that the RNC/BSC is to notify the UE of returning to the LTE network.
