METHOD AND APPARATUS FOR PERFORMING HANDOVER BETWEEN 3GPP LTE NETWORK AND ALTERNATIVE WIRELESS NETWORK Russian patent published in 2011 - IPC H04W36/14 

FIELD: information technology.

SUBSTANCE: 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.

EFFECT: ensuring service continuity.
