ABSTRACT:
Voice packets transmitted by an originating wireless user for use in a half-duplex communication mode in a one to many communication session are monitored for an unexpected cessation. If an unexpected cessation of such voice packets is detected for a predetermined time period, the session server controlling the communications session is notified to release the supporting half-duplex communication paths associated with the originating user.
