Abstract
A cellular telephone call administration system processes detailed call records from a cellular switch as the calls are processed. This arrangement expedites automatic, electronic distribution of detailed call records to resellers and service provider billing facilities and to the roam billing clearing house. The call administration system, without operator intervention, provides a metered billing class of service to customers as an aid to controlling their cellular communication expenses; and provides for registration of roam sets for service on a cellular switch without need for a billing agreement with the set's home carrier.
