Abstract

A method of managing a group call involving a number of mobile communications devices include a network node identifying a radio access node adjacent a first radio access node. The method also includes a serving node creating the Group Call Area on basis of the first and adjacent radio access nodes. The method also includes establishing a signalling channel within a cell corresponding to the adjacent radio access node. The signalling channel includes an identifier corresponding to the Group Call area. The radio access nodes, or base stations, that have established a data communications channel with the mobile communications device have traffic and signalling channels established therein and are marked as an active cell of the Group Call Area.
