Abstract
A fast return method for CSFB user equipment, includes: receiving a trigger message sent by a mobile switching center MSC, where the trigger message is used to trigger release of a circuit switched CS service of CSFB user equipment UE, and the UE runs both the CS service and a packet switched PS service; and sending a radio resource control RRC connection release message to the UE according to the trigger message, so as to trigger the UE to release a radio bearer of the CS service, a radio bearer of the PS service, and an RRC connection according to the RRC connection release message and fast return to a Long Term Evolution LTE network. According to embodiments of the present invention, a delay for the CSFB user equipment to return to the LTE network can be reduced, thereby improving user experience.
