The base station controller transmits the received transmitting request and receiving response to a mobile switching center(S305). The mobile switching center transmits a connection request to the base station controller(S306). The base station and the base station controller are a connection request and a response each other(S307). A processor of the base station transmits a traffic channel assignment message composed as parameters needed for an initialization of the traffic channel to a traffic channel element(S308). The traffic channel element initializes a transmission modulator using the parameters of a traffic channel assignment message, assigns a power of a forward traffic channel according to a determined initial traffic channel gain, and transmits a null traffic to the mobile station(S309).
