PROVIDING ROAMING STATUS INFORMATION FOR SERVICE CONTROL IN A PACKET DATA BASED COMMUNICATION NETWORK

摘要

A method for providing roaming status information for service control in a packet data based mobile communication network including one or more terminal devices. In response to a change detected in the state of a connection between a terminal device and a gateway node, roaming status information on the terminal device is derived and a request is made for service policy for the subscriber of the terminal device. The request, including the derived roaming status information, is sent from the gateway node to a session control means. A service policy indicating which subscriber services are allowed for the subscriber and rules for the subscriber services is generated.
