Geographical restriction of services in a packet data telecommunications network
First Claim
1. A method of restricting geographical use of a service for a mobile terminal (MT) in a packet data network, the method comprising the steps of:
- receiving, at a packet data service node (PDSN) from an access node (AN), a registration request message for requesting packet data service, wherein the registration request includes a cell information;
translating, at the PDSN, the cell information into a zone ID;
storing, at the PDSN, the zone ID, wherein the zone ID is stored in a first table;
sending, from the PDSN to an Authentication, Authorization, Accounting (AAA) server, an access request message for authenticating the MT;
receiving, at the PDSN 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;
comparing, at the PDSN, the allowance information with the zone ID;
if the allowance information is different from the zone ID in the first table;
setting up, at the PDSN, a filter for the MT; and
rejecting, at the PDSN, the packet data for the requested packet data service.

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.

10. A Packet Date Service Node (PDSN) for providing packet data service to a Mobile Terminal (MT) in a packet data network, wherein the PDSN comprises:
-
an Input/Output unit for receiving a registration request message for requesting packet data service, wherein the registration request includes a cell information, receiving an access accept message for authorizing the MT to receive packet data service, wherein the access accept message includes an allowance information;
a processor for translating the cell information into a zone ID, comparing, at the PDSN, the allowance information with the zone ID and if the allowance information is different from the zone ID in the first table the processor set up a filter for the MT and reject the packet data for the requested packet data service; and
a database for storing the zone ID in a first table. - View Dependent Claims (11, 12, 13)
