1. An access point and subscriber terminal initialization method comprising:

  • sending a request via a signaling channel to a broadband access network terminal;

    forwarding a wireless local area network mobile radio service controller request by the broadband access network terminal to a wireless local area network mobile radio service controller in order to authenticate and validate a subscriber;

    performing broadband access network terminal and wireless local area network mobile radio service controller processing;

    receiving an indication regarding an authentication of the subscriber;

    using the indication to determine if the subscriber failed the authentication;

    sending a “

    nack”

    to the broadband access network terminal and to the access point if the subscriber failed the authentication;

    forwarding by the wireless local area network mobile radio service controller a multicast address to the broadband access network terminal if the subscriber was authenticated;

    sending by the broadband access network terminal an “

    ack”

    to the wireless local area network mobile radio service controller;

    investigating by the broadband access network terminal in order to determine a session status;

    one of (a) initializing by the broadband access network terminal a wireless local area network mobile radio service controller session by engaging multicast processes if the session is a new session or (b) including a new subscriber internet protocol address if the session is an on-going session;

    sending an “

    ack”

    to the access point;

    assigning by the access point time slots in a superframe;

    sending an “

    ack”

    to the subscriber with the multicast address;

    receiving an indication form the access point as to a receipt of the multicast address; and

    initializing by the subscriber terminal and going into a “

    listen mode”

    if the access point received the multicast address.
