Abstract:
1. A method for processing a call in an asynchronous mobile communication system, wherein an asynchronous mobile station includes a call control (CC) entity, a mobility management (MM) entity and a radio resource controller (RRC); an asynchronous radio network includes a radio resource controller (RRC); and a synchronous core network is interlocked, the method comprising the steps of: a) setting up the call in case a calling call message is generated in the mobile station; b) establishing a channel between the asynchronous mobile station and the asynchronous radio network; c) handling basic information for assigning a radio resource; d) performing a cipher establishment; e) establishing the radio resource; f) performing a configuration for a service; and g) transmitting a phone call stand-by message to a user, wherein the step a) includes the steps of: a1) transmitting the calling call message generated in the CC entity of the asynchronous mobile station, to the RRC of the asynchronous mobile station; a2) requesting the RRC of the asynchronous radio network of a connection, through a common control channel (CCCH); and a3) transmitting a connection completion message and information of a dedicated control channel (DCCH), through the CCCH, to the asynchronous mobile station, after receiving the request of the connection, wherein the step b) includes the steps of: b1) establishing the DCCH that the asynchronous mobile station is required to use, based on the information of the DCCH received from the asynchronous radio network; b2) transmitting information of the asynchronous mobile station capability, through the DCCH, to the asynchronous radio network; b3) receiving a confirmation response of the information of the asynchronous mobile station capability from the asynchronous radio network; and b4) transmitting the calling call message, through the DCCH, to the asynchronous radio network.
