Unlicensed mobile access network (UMAN) system and method
First Claim
1. In an unlicensed mobile access (UMA) system having a UMA device a UMA network controller (UNC), wherein said UMA system communicates with a core network comprising a mobile switching center (MSC) and a serving general packet radio service support node (SGSN), a method for communicatively coupling said UMA device and said core network, said method comprising:
- a) using a first protocol standard that carries audio data to communicatively couple said UNC and said UMA device;
b) relaying a subset of messages of the first protocol standard from the UNC to the core network, wherein said subset of messages are in a second protocol that is a subset of the first protocol;
c) wherein said first protocol standard comprises a set of messages for performing discovery and registration operations; and
d) wherein said relaying is without translation of said set of messages of the first protocol.

Abstract
Some embodiments provide a system for handling communications between an unlicensed mobile access (UMA) network controller (UNC) and a licensed wireless communication system. The systems of these embodiments include a serving general packet radio service support node (SGSN) or a mobile switching center (MSC) that is communicatively coupled to the UNC. In such systems the UNC and the SGSN communicate utilizing a subset of a protocol standard message set. The protocol standard message set includes messages for handing discovery and registration, circuit switching domain and packet switching domain signaling, and circuit switching based data and packet switching based data. The subset for the SGSN is for handling packet switched domain signals and packet switching based data. The subset for the MSC is for handling circuit switched domain signals and circuit switching based data.
