1. In a wireless communication system including a plurality of technologically diversified access networks and at least one multi-stack wireless transmit/receive unit (WTRU), the multi-stack WTRU including a protocol stack including a media independent handover (MIH) function, a method for establishing a communication link with the access networks, the method comprising:

  • (a) activating the WTRU and initializing the MIH function;

    (b) the WTRU scanning for an access network;

    (c) the WTRU detecting beacon frames transmitted by an access network;

    (d) the WTRU reading the content of the detected beacon frames if it determines that the beacon frames support MIH information;

    (e) the WTRU passing MIH information found in the beacon frames to the MIH function; and

    (f) the MIH function processing the MIH information and establishing a communication link with the access network.
