Abstract
A telecommunications system and method is disclosed for defining location-based group services, which can be implemented within a Group Call Services (GCS) node associated with a cellular network. When a group call is initiated, the GCS can send a positioning request to a Mobile Location Center (MLC) to locate the group members within a specified area. The particular location can be defined by the group number or the location can be prompted by the GCS. For each group member, the position of a mobile terminal associated with that group member is determined and the call is set up only to those members which the meet the specified area criteria. If none can be located within the specified area, the area can be expanded at the callers request.
