TDD-RLAN wireless telecommunication system with RAN IP Gateway and methods
First Claim
1. A method of mobility management using a radio local area network (RLAN) for providing concurrent wireless telecommunication services for a plurality of user equipments (UEs) where an associated core network (CN) supports Authentication, Authorization and Accounting (AAA) functions of UEs comprising:
- providing a RLAN for conducting time division duplex (TDD) code division multiple access (CDMA) wireless communications with UEs in a RLAN service region including;
a first base station having a transceiver for establishing UE connections with in a portion of said RLAN service region;
a first Radio Network Controller (RNC) coupled with said first base station for controlling base station communication; and
a Radio Access Network Internet Protocol (RAN IP) Gateway coupled with said RNC having a General Packet Radio Service (GPRS) connection with the Internet and being configured to communicate Authentication, Authorization and Accounting (AAA) function information to a Core Network;
establishing a wireless connection between a first UE within said selected portion of said RLAN service region and a second UE outside of said RLAN service region for conducting a communication of user data;
conducting AAA functions for said communication between said first and second UEs using said Core Network; and
using said General Packet Radio Service (GPRS) connection with the Internet for transporting user data of said communication between said first and second UEs.

Abstract
The present invention provides for a Time Division Duplex—Radio Local Area Network (TDD-RLAN) which includes a Radio Access Network Internet Protocol (RAN IP) gateway that enables connectivity to the public Internet. The system may serve as a stand-alone system or be incorporated into a UMTS used with conventional Core Network, particularly for tracking and implementing AAA functions in the Core Network.
