Service access control interface for an unlicensed wireless communication system
First Claim
1. A method of performing discovery transactions for an unlicensed mobile access (UMA) network comprising an unlicensed network controller, wherein the unlicensed network controller comprises an IP network controller (INC) communicatively coupled to a licensed wireless communication system, wherein the unlicensed network controller comprises a security gateway communicatively coupled to the INC, the method comprising:
- a) authenticating a mobile station (MS) into the unlicensed network controller by a first server communicatively coupled to the security gateway;
b) sending a discovery request message from the MS to the INC through the security gateway;
c) sending a set of attributes from the INC to a second server;
d) authorizing said discovery request by the second server utilizing a set of databases; and
e) sending a result of said authorization from the second server to the INC.

Abstract
Some embodiments provide a system for authorization and authentication of an unlicensed mobile access (UMA) subscriber. The system includes an UMA network controller (UNC) which is communicatively coupled to a licensed wireless communication system. The system also includes an access point (AP) that serves a wireless local area network (WLAN). The system further includes a mobile station (MS) that is communicatively coupled to the AP and the licensed wireless communication system. The system also includes an authentication server that is communicatively coupled to the UNC. The authentication server authenticates a UMA subscriber for accessing an unlicensed mobile access network (UMAN) that includes the UNC and the AP.
[Some embodiments define an interface between the UNC and the authentication server uses Remote Access Dial-In User Service (RADIUS) protocol. In some embodiments, the authentication server is an Authorization, Authentication, and Accounting (AAA) server.]
