A method and apparatus for providing a dispatch system in a cellular radiotelephone system. Membership in a dispatch group is implicitly created by assigning a common telephone number to all members of the dispatch group and/or explicitly by association of the mobile stations with one or more dispatch groups in a centralized database o f a cellular telephone network. A telephone call placed by a dispatcher or mobile stations having membership in the dispatch group results in the cellular telephone network contacting each of the members of the dispatch group to create a full duplex conference call betwee n all members of the dispatch group. In one embodiment of the present invention, the telephone calls to the mobile stations are conferenced together at the gateway to the cellular telephone network, and in another embodiment of the present invention, the telephone calls to t he mobile stations are hierarchically conferenced together.
