ABSTRACT:
A method and a Packet Data Service Node (PDSN) of restricting geographical use of a service for a mobile terminal (MT) in a packet data telecommunications network. The PDSN receives from an access node (AN), a registration request message having a cell information for requesting. The PDSN translates the cell information into a zone ID, stores the zone ID in a first table and sends to a AAA server, an access request message for authenticating the MT. PDSN further receives from the AAA server, an access accept message for authorizing the MT to receive packet data service, wherein the access accept message includes an allowance information. Afterwards the PDSN compares the allowance information with the zone ID. If the allowance information is different from the zone ID in the first table, the PDSN set up a filter for the MT and rejects packet data for the requested packet data service.
