1. In a mobile telecommunications network in which a plurality of mobile stations communicate through a radio access network (RAN) through a network having at least one Serving GPRS Support Node (SGSN) and at least one Gateway GPRS Support Node (GGSN) through the Internet to a plurality of servers, a system for the automatic optimization of traffic comprising: one or more G b probes for extracting information from the interface between the RAN and the SGSN including the identity of each user associated with a specific data flow; a network management system (NMS) for providing congestion and traffic information from the RAN; a customer database for providing information regarding the type and quality of service for each user of a mobile station; a policy decision point wherein information from the G b probes, the NMS and the customer database is used to determine actions to be taken to optimize traffic for each data flow on a cell-by-cell basis; and, a traffic optimizer for implementing the actions determined by the policy decision point.
