Abstract

Providing virtual talk groups to an endpoint includes managing the virtual talk groups, where a virtual talk group comprises one or more members operable to participate in the virtual talk group. One or more overlapping members are identified, where an overlapping member is a member of more than one virtual talk group. Internal virtual talk groups are generated from the original virtual talk groups, where the internal virtual talk groups comprise at least a reduced number of overlapping members. One or more original virtual talk groups are provided to the endpoint using the internal virtual talk groups.
