Abstract
Group calls can be provided between an originating terminal and a called terminal on a radiotelephone communications system including a switching center and a plurality of radio base stations wherein each of the radio base stations defines a cell and wherein each of the originating and called terminals is in one of the cells. In particular, a group call origination message can be received from the originating terminal, and after receiving the group call origination message, a group call setup message can be sent to a radio base station defining a cell within which the called terminal is located. After sending the group call setup message, first and second traffic channels can be designated for the originating terminal to provide communications between the originating and called terminals. Related systems are also discussed.
