First Claim
1. A method of providing Internet access to a mobile subscriber operating a mobile station in a visited service area served by a serving Mobile Switching Center (MSC) disposed in a radio telecommunications network, said network including a home service node having a Home Location Register (HLR) and a Service Control Point (SCP), comprising the steps of:
- storing in the home service node, a subscriber service category associated with the mobile station for identifying an Internet Service Provider (ISP);
storing at least one routing number for the identified ISP in an ISP database;
determining in the serving MSC that the mobile station has initiated an Internet access service;
sending a message from the serving MSC to the home service node to invoke the Internet access service, the message including a service trigger for the mobile subscriber, a plurality of digits dialed and a location information portion relating to at least one of the mobile station and the serving MSC'"'"'s location;
determining, in the home service node, the identity of the ISP for the mobile subscriber based on the message;
interrogating, by the home service node, the ISP database associated with the ISP to determine a routing number for an ISP server location that is local to the serving MSC; and
returning the routing number to the serving MSC for establishing a trunk connection to the ISP server location.

Abstract
A system and method of providing Internet access to a roaming mobile subscriber located in a visited service area served by a serving MSC of a radio telecommunications network. The radio telecommunications network includes a home service node which comprises a Home Location Register (HLR) and a Service Control Point (SCP). The home service node stores a subscriber service category associated with the mobile subscriber for identifying an Internet Service Provider preferred by the mobile subscriber. An ISP database associated with the identified ISP is coupled to the home service node. When the roaming mobile subscriber initiates an Internet access service while located in the visited service area, the serving MSC sends a message to the home service node in response thereto. Preferably, the message includes a service trigger for the mobile subscriber, a plurality of digits generated pursuant to initiating the Internet access service, and a location information portion relating to the mobile subscriber'"'"'s location and the location of the serving MSC. A switch identity may also be provided therewith. Based on the contents of the message, the home service node determines the identity of the preferred ISP and interrogates the ISP database to determine a routing number for an ISP server location that is most proximately local with respect to the location of the mobile subscriber or the serving MSC. When the routing number is returned to to the serving MSC, it establishes a trunk connection to the ISP server location for providing Internet acces.
