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.
