Abstract

New services and/or new subscribers are efficiently and flexibly defined and added to a mobile communications network using service groups and service group identifiers. One or more groups of mobile subscribers are defined, and a group identifier is assigned to each member of the group. One or more services are established for the group of mobile subscribers and are associated with the group identifier. In particular, the group identifier links each member of the group with the established services. Using this service group approach, existing mobile communications system nodes are readily updated with new service and subscriber information. Likewise, subscriber service information may be easily restored to corrupted mobile databases. Advantageously, the signaling and time required to perform location update procedures as mobile units move between different location areas in a mobile communications system are considerably reduced.
