<p>A controller (103) for a dispatch communications system (100) that is arranged and constructed for limiting a transmission in the dispatch communications system, methods thereof, and communications units (115, 117, 123) for use within the system have been discussed. The controller comprises: a processor (405), cooperatively operating with a transceiver (403), to grant and provide a first right to talk to a first user (203), monitor a dispatch call resulting from the grant of the first right to talk to the first user to evaluate whether the first user should retain the first right to talk (207, 209), and notify, when the evaluation so determines, a second user (211) that the first right to talk is no longer applicable.</p> |
