Abstract: A user equipment and a circuit-switched fallback method thereof are provided. An initial base station sends a radio resource control connection release message containing the redirection frequency list to the UE. The redirection frequency list includes at least one redirection frequency. The UE determines a priority of the at least one redirection frequency according to a current registered LAI, a learning database and a piece of signal reference information of the redirection frequency list. Accordingly, the UE executes a circuit switch fallback procedure according to the priority of the at least one redirection frequency.

Abstract: Aspects of the disclosure provide a method for setting up a call for a user equipment. The method includes receiving, by the user equipment, a measurement configuration message that specifies a set of measurement events corresponding to poor signal quality between the user equipment and a packet-switched network, and sending, by the user equipment, a measurement report when one of the set of measurement events occurs while performing a first call setup process for setting up the call using the packet-switched network. The method also includes terminating the first call setup process after sending the measurement report that indicates poor signal quality between the user equipment and the packet-switched network, and sending, by the user equipment, a service request to begin a second call setup process for setting up the call for the user equipment using a circuit-switched network after terminating the first call setup process.
