Abstract
A method, system, and mobile station are presented for informing a packet control unit (PCU) whether the dual transfer mode (DTM) capable mobile station has an ongoing circuit switched connection and is in dedicated mode. The packet control unit will typically be located at a base station. Upon entering the dedicated mode, the mobile station alerts the PCU of entry into the dedicated mode, using a mobility management (MM) procedure. This mobility management procedure is utilized for alerting the PCU about the dedicated mode, regardless of physical movement of the mobile station such as movement from one cell to another.
