COMMUNICATION APPARATUS AND CIRCUIT CALL SERVICE METHOD OF THE COMMUNICATION APPARATUS

摘要

PURPOSE: A communication apparatus and a circuit call service method thereof are provided to disperse traffic so that traffic is not concentrated in the specific FA(Frequency Allocation) of WCDMA(Wideband Code Division Multiple Access) in a CSFB(Circuit Switched Fall Back) technology. CONSTITUTION: In case a circuit call is received or the circuit call is transmitted from a terminal about a terminal receiving the service of a first communication system, a determining unit(111) determines FA to process a circuit call based on at least one FA traffic among one or more FA of a second communication system. An information providing unit(112) provides information about the determined FA about the terminal. The information providing unit inserts information about the determined FA into an RRC(Radio Resource Control) disconnection massage. The information providing unit provides the RRC disconnection massage to the terminal. [Reference numerals] (111) Determining unit; (112) Information providing unit; (113) Input unit; (120) Terminal
