Service access control interface for an unlicensed wireless communication system

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.
