Abstract
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.
