Abstract
A time division multiple access cellular communication system supports a packet channel is alterable between a packet control channel configuration and a packet traffic channel configuration. In the packet control channel configuration, the packet channel may provide only control functions or a combination of control and traffic functions. The packet channel may also be configured in a packet traffic configuration so that the packet channel provides only packet traffic functions. In this configuration, another packet channel must be configured in the packet control channel configuration to provide control functions for the packet traffic only packet channel. A Digital Control Channel (DCCH) includes information relating to a Beacon Packet Control Channel (PCCH), which contains information on the allocated packet channels. The subscriber unit initiates its packet data operations within the system. When packet data operations are reconfigured, the Beacon PCCH information is altered and the subscriber unit may obtain the new configuration information from the Beacon PCCH.
