摘要： A method and an apparatus for securing media independent handover message transportation are provided. The method for securing media independent handover message transportation, include: performing an authentication procedure by a terminal with an access router to generate a master session key; transmitting the generated master session key and address information of the terminal to an information server by the access router; generating an information server key to be used in transmitting and receiving a message by the information server with the terminal using the received master session key and the address information of the terminal; and forming a secure channel by the terminal and the information server using the generated information server key. Since a key formed at a layer 2 is used in an MIH authentication step being a layer 3 not to repeatedly create a secure key, a security procedure may be rapidly performed.

摘要： A wireless transmit/receive unit (WTRU) may include a media application that receives data from a media server via a link on a downlink (DL) -only radio access network. The link on the DL-only radio access network may be handed over to a second DL-only radio access network. A mobility management server, such as a Media Independent Handover (MIH) server, may communicate with the WTRU via a second radio access network that is a bidirectional radio access network to facilitate the handover. MIH messages may include fields that relate to DL-only radio access technologies may be used to facilitate handover of a DL-only link. Further, MIH broadcast or multicast messages may be used to facilitate the handover of a DL-only link.

摘要： An apparatus for providing security to media independent handover service includes a point of service for providing the media independent handover services including an independent authenticator. The independent authenticator authenticates candidate access networks prior to the handover of the mobile devices from serving access networks to the candidate access networks, where each of the serving access networks and the candidate access networks belong to a plurality of heterogeneous access networks having the specific serving media. An access controller applies an access control through an access authentication with the point of service providing the media independent handover services through an authentication server, in which when the access authentication is established between the point of service and the authentication server, the mobile devices are authorized to access the media independent handover services through the point of service for the mobile devices attached between heterogeneous media.
