Abstract  Abstract

A method for switching a radio access technology, RAT, between a plurality of wireless communications systems implemented in practice in a wireless transmission / reception unit (WTRU) with multiple modes of operation, configured to support more than one RAT, characterized by: receiving (204), from a wireless communications system, an indication of the existence of a wireless communications system that works with others that executes in practice a different RAT which is available in a coverage area of each of a plurality of wireless communication systems through a wireless communication system currently connected, in response to a report specifying the WTRUs ability to support the system RAT wireless communications that works with others; If a predetermined criterion for inter-system handover to transfer the WTRU from the wireless communications system currently connected to the wireless communications system that works with others is met, request a list of Service Establishment Identifiers (SSID) ), from the currently connected wireless communications system; receive the SSID list of the currently connected wireless communications system; receive information regarding the wireless communications system that works with others in which it is determined to transfer the WTRU to the wireless communications system that works with others; and initiate (210) a transfer of the wireless communications system that works with others using the information received, whereby the WTRU continues to receive the same services that the WTRU received from the wireless communications system currently connected through the wireless communications system That works with others.
