1. A radio local area network (RLAN) for providing concurrent wireless telecommunication services, including voice services, for a plurality of user equipments (UEs) between UEs and/or the Internet comprising:
- a first base station having a transceiver for conducting time division duplex (TDD) code division multiple access (CDMA) wireless communications with UEs in a selected geographic region including voice services using a first compression protocol for voice data;
a first controller means coupled with said first base station configured to control user data flow and control signaling for base stations communication;
a Radio Access Network Internet Protocol (RAN IP) Gateway coupled with said controller means RNC using a stacked, layered protocol connection having a lower transport layer configured to use Internet Protocol (IP); and
said Radio Access Network Internet Protocol (RAN IP) Gateway having a Gateway General Packet Radio Service (GPRS) Support Node (GGSN) for connection with the Internet via an internet service provider (ISP) having a voice gateway that converts compressed voice data and Pulse Code Modulation (PCM) signaling using said first compression protocol.

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.
