Abstract
A wireless network with a group call capability. The wireless network includes a mobile switching center connected to a plurality of base stations each serving a portion of the wireless network and communicating with mobile stations on a plurality of channels. Each base station allocates one of the channels for the group call. Each mobile station in the group sends an acknowledgement of the group call to the base station serving the area where the mobile is located. Each base station that did not receive an acknowledgement frees the allocated channel for use in other calls.
