Abstract: PURPOSE: A medium speed data call handoff method in a mobile communication system is provided to carry out an efficient auxiliary traffic channel handoff through the assignment and release of a suitable traffic channel according to a backward traffic channel state and a signal message of a mobile station in the state that a physical auxiliary traffic channel is connected. CONSTITUTION: A mobile station measures the pilot signal strength of active set base stations, regardless of T_DROP(S1). The mobile station judges whether there is a pilot signal having a strength that the pilot signal strength of a base station not having an allocated auxiliary traffic channel is larger than the pilot signal strength of a base station having an allocated auxiliary traffic channel(S2). As a result of judgment, if the pilot signal strength of the base station not having an allocated auxiliary traffic channel is smaller than the pilot signal strength of the base station having an allocated auxiliary traffic channel, the mobile station transmits such information to a serving base station through a pilot strength measurement message and checks it continuously for a required time(S4). If the pilot signal strength of the base station not having an allocated auxiliary traffic channel keeps smaller than the pilot signal strength of the base station having an allocated auxiliary traffic channel more than the given time, the mobile station transmits a signal strength message, recording pilot information and pilot strength, to the serving base station(S6). The serving base station forwards the message to a base station controller. A call control processor in the base station controller analyzes the signal strength message and releases the auxiliary traffic channel of the base station having the allocated auxiliary traffic channel. The call control processor selects a base station having a low backward frame error rate among the active set base stations not having allocated auxiliary traffic channels and allocates an auxiliary traffic channel.
