ABSTRACT:
Methods for operating and administering mobile station user groups in a wireless communications system. In one embodiment, a user group identification code is assigned to a plurality of mobile stations to form a user group, wherein the number of mobile stations in the user group is less than the total number of mobile stations in the entire communications system, and wherein the user group identification code is distinguishable from a unique mobile station identification code associated with each mobile station in the user group. A page message from the system to the user group is transmitted using the user group identification code when a terminating call to the user group is requested. A user group specific page indication is then generated at the mobile stations indicating to a user of each mobile station that the page message has been received. A page response message is then transmitted to the system from mobile stations whose users acknowledge the page indication. Finally, a channel assignment for the call is granted to the mobile station which responds first.
