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.
