METHOD AND APPARATUS FOR PERFORMING A HANDOVER PROCEDURE BETWEEN A 3GPP LTE NETWORK AND AN ALTERNATIVE WIRELESS NETWORK

摘要

In a wireless communications system including a third generation partnership project (3GPP) long term evolution (LTE) network, at least one alternative wireless network, and a wireless transmit/receive unit (WTRU), the 3GPP LTE network sends an indication of the availability of the alternative network or a list of available alternative networks in an area where the WTRU is located. The WTRU receives the information and initiates a handover procedure to the alternative wireless network based on the information. The WTRU may request a list of alternative wireless networks from the 3GPP LTE network, or may send capability information to the 3GPP LTE network. The alternative wireless network may be a 3GPP network, an interworking wireless local area network (I-WLAN), or a fixed broadband network.
