Abstract

A method of managing a call group by a number of mobile devices in a mobile telecommunications network. The mobile telecommunications network includes a serving node in communication with the mobile devices. The method includes 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.
