Abstract
Abstract An apparatus and method for controlling mode transition in a traffic channel substate in a mobile communication system. If a control hold mode should be transited to an active mode a BSC sets a transmission rate on a DCCH in use to a continuous rate and transmits the continuous rate information to a BTS that an MS is within the coverage area of the BTS. Then, the BSC allocates an additional required channel besides the DCCH. If an active mode should be transited to a control hold mode, a BSC sets a transmission rate on a DCCH in use to a predetermined gating rate and transmits the gating rate information to a BTS that an MS is within the coverage area of the BTS. Then, the BSC releases an additional required channel besides the DCCH.
