A method and system for integrating media independent handover (MIH) under IEEE 802.21 and unlicensed mobile access (UMA) are disclosed. A public land mobile network (PLMN) and an unlicensed mobile access network (UMAN) are concurrently deployed. UMA is supported such that a multi-mode wireless transmit/receive unit (WTRU) may access the UMAN to receive PLMN services through the UMAN. MIH entities are included both in the WTRU and the UMAN and the MIH entity of the WTRU monitors handover events and information and generates a handover trigger for handover between the PLMN and the UMAN. The MIH entity in the UMAN interacts with the MIH entity of the WTRU to report a remote event, handover information and command.

La présente invention concerne un procédé et un système permettant d'intégrer le transfert indépendant des supports ou MIH (Media Independent Handover) sous IEEE 802.21 et l'accès aux mobiles sans licence ou UMA (Unlicensed Mobile Access). Un réseau mobile terrestre public ou PLMN (Public Land Mobile Network) et un réseau d'accès aux mobiles sans licence ou UMAN (Unlicensed Mobile Access Network) sont déployés concurremment. L'UMA est accepté de façon qu'un émetteur/récepteur radio ou WTRU (Wireless Transmit/Receive Unit) multimode puisse accéder au réseau UMAN pour recevoir les services PLMN via l'UMAN. Des entités MIH sont incluses dans le WTRU ainsi que dans l'UMAN, et l'entité MIH du WTRU surveille les événements de transfert et l'information, et génère le déclenchement de transfert pour le transfert entre le PLMN et l'UMAN. L'entité MIH dans l'IMAN interagit avec l'entité MIH du WTRU pour faire état d'un événement, d'une information de transfert et d'une commande de transfert.
