Abstract
A dispatch service is provided for a cordless communication system. The system includes a dispatch group that includes multiple portable parts (PP's). When an originating PP desires to engage in a dispatch communication, the PP selects a traffic bearer over which to transmit, reserved the selected traffic bearer via a fixed part (FP), and identifies the reserved traffic bearer to the other members of the dispatch group via the FP. The other members tune to the identified traffic bearer and the originating PP begins transmitting. When the originating PP is finished transmitting, the originating PP releases the reserved traffic bearer and another member of the dispatch group may then transmit on the reserved traffic bearer. A handoff is also provided in the event that the signal performance of the reserved traffic bearer degrades to an unacceptable level and an acceptable traffic bearer is available.
