Method for switching technology radio access between wireless communication systems with a unit of wireless transmit / receive with multiple operating modes.

摘要

A method of switching technology access to radio, RAT (its acronym in English) between a plurality of wireless communication systems implemented in practice in a unit of wireless transmit / receive (WTRU, its acronym in English) with multiple operating modes, configured to support more than one RAT, characterized by: receiving (204) from a wireless communication system, an indication of existence of a wireless communications system that works with others running in practice a different RAT that 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 capability of the WTRU to support the RAT system wireless communications with other works; If a default value for handover between systems to transfer the WTRU from the wireless communications system currently connected to the wireless communications system that works with other criteria are met, request a list of identifiers Service Establishment (SSID, its acronym in English ), from wireless communications system currently connected; Receive listings SSID wireless communications system currently connected; receive information concerning the wireless communication system working with others is determined that the WTRU to transfer to the wireless communications system that works with others; and initiating (210) a handover of the wireless communication system that works with others using the received information, whereby the WTRU continues to receive the same services that the WTRU received from the wireless communications system currently connected via the wireless communication system He is working with others.
