A system and method for radio disconnect and channel access for digitised speech trunked radio systems.

摘要

In half-duplex, trunked digitised voice communications between mobile transceivers, the present invention minimises time delays occurring after one transceiver ends a transmission and before other transceiver communications may commence. A disconnect signal is transmitted from the currently transmitting transceiver during a time frame (4#) immediately following indication that a current communication has ended. Channel access time delays are minimised by permitting speech input to a transmitting transceiver immediately upon receipt of a working communications channel. The present invention has particular applicability in trunked TDMA radio communication systems. <IMAGE>
