A mobile telecommunication system supporting location based billing of data services is provided. The mobile telecommunication system includes a plurality of routing areas each having one or more base transceiver stations therein for providing a radio interface to a mobile terminal. A service node provides data services to the mobile terminal in two or more of the routing areas. The service node opens a mobility call detail record and a location container therein when the mobile terminal attaches to the mobile telecommunication system. The service node opens a packet data protocol call detail record and a traffic volume container when the mobile terminal activates a data session with the service node. The traffic volume container counts data service traffic volumes transferred to and from the mobile terminal. The location container is automatically closed when the mobile terminal roams from one routing area to a second routing area. The contents of any traffic volume containers are reported via a partial record to a node in the telecommunication system upon closure of the location container thus limiting, at any given moment, the traffic volume count in any traffic volume container to traffic volume transfers in a single routing area. Counts of subsequent data transfers are made in a zeroed traffic volume container. An operator of the mobile telecommunication system may then implement location based billing of data services by levying different fees for data services obtained by the mobile terminal in different routing areas.
