LOCATING CONTROL SIGNALS IN A MOBILE COMMUNICATIONS SYSTEM

摘要

A mobile communications system (10) includes a first link and a second link (e.g., a circuit-switched link and a packet-switched link). When a mobile unit (20) is initialized in the mobile communications system (10), it identifies a first control signal, such as the digital control channel (DCCH) of an IS-136 system, of the first link. From information associated with the first control signal, the mobile unit (20) determines the existence of the second link. From information identifying a current frame structure in the first link, a pointer to the current frame structure of the second link can be derived.
