A method for providing enhanced floor control (500) between a dispatch communications network and a cellular telephone communications network includes transmitting a transmit delay message (517) by a network control entity (505) to a communications device (501) in the cellular telephone network when a talk reservation request (515) has first been granted to a communications device (507) in the dispatch network. A transmit grant message (521) is then transmitted from the network control entity (505) to the communications device (501) in the cellular telephone network when the communications device in the dispatch network switches from a transmit mode to receive mode (507). The transmit grant message signals the communications device (501) in the cellular telephone network enabling it to access the dispatch communications network without sending a second talk reservation request.
