1. An apparatus for providing a dispatch call in a communication system, the apparatus comprising:
- a controller coupled to a hang timer and to a session timer;
wherein the hang timer causes a channel to be dropped after a first threshold;
wherein the session timer causes participants to the dispatch call to be reset to an original configuration after a second threshold;
the first threshold is substantially equal to 4 seconds; and
the second threshold is substantially equal to 40 seconds.

Abstract
In addition to a hang timer (405), a second timer (403) (session timer) is introduced. A base station (101, 102) monitors a dispatch call, and if there exists no activity for a period of time greater than the hang-timer threshold, the base station (101, 102) will drop the over-the-air channels broadcasting the call to the remote units (113-118). All active participants to the call will be maintained until the session timer expires. Once the session timer expires, the talk-group participants will be reset to their original members.

9. A method for providing a dispatch call within a communication system, the method comprising the steps of:
-
providing the dispatch call to a first plurality of remote units;
receiving an option message, wherein the option message comprises instructions to exclude or include a remote unit in the dispatch call;
providing the dispatch call to a second plurality of remote units in response to the option message;
determining that a hang timer has expired;
dropping all over-the-air channels in response to the hang timer exceeding a first threshold of substantially 4 seconds;
receiving a request to provide the dispatch call;
determining if a session timer has exceeded a second threshold of substantially 40 seconds; and
providing the dispatch call to the first plurality of remote units if the session timer has expired, otherwise providing the dispatch call to the second plurality of remote units. - View Dependent Claims (10, 11)
