    摘要: A method and apparatus for performing a handover are disclosed. An Internet protocol (IP) multimedia subsystem (IMS) client registers with an IMS network and establishes an MIH session with an MIH application server using an SIP. The IMS client establishes a session for IP-based service, (e.g., VoIP), with a communication peer using SIP messaging. MIH messages are exchanged for handover with the MIH application server over IP using SIP messages by encapsulating the MIH messages in SIP instant messages. Alternatively, the MIH messages may be exchanged with the MIH application over IP by sending equivalent SIP messages in place of the MIH messages.

    摘要: The present invention modifies existing media independent handover (MIH) function (MIHF) frame format as defined by the IEEE 802.21 standard. In one embodiment, the variable load of the MIHF frame is modified to eliminate the MIHF variable header by defining the MIHF identification (ID) field and the session ID field as fixed fields in the MIHF fixed header. Thus, the MIHF variable load is only made up of the MIHF payload. In another embodiment, a field such as an information element (IE), a header, or MIH service data such as a command or an event, is represented by a type field, a length field and a value field (TLV). The length of the value field is exactly 128 octets, and the length field only occupies one octet.

    摘要: Methods are presented wherein a WTRU may determine, based on measurements, that it is a victim of interference from another cell such a closed subscriber group (CSG) cell. In addition, methods are presented for the UE to inform the CSG cell that UE is present and is a victim UE. Methods for informing the CSG cell may include the grant of temporary membership to a victim UE, the use of a connected WTRU as a relay, and/or indicating victim status in a control message. The indication may trigger an interference management procedure. Methods for the WTRU to stop interference management at the CSG cell, methods to allow the use of a training period by the CSG eNB to allow for non-CSG WTRUs to report their presence, and methods to indicate how to perform UE Victim Indication are also presented.

    摘要: A first media independent handover function (MIHF) receives a media independent handover (MIH) capabilities discovery request from a second MIHF and generates a MIH capabilities discovery response message, including one or more parameters. Then the first MIHF then sends the MIH capabilities discovery response to the second MIHF. Based on the information contained in the MIH capabilities discovery response, the first MIHF may receive a handover request message from the second MIHF. The one or more parameters included within the discovery response message indicates the specific technologies for which the first MIHF supports a MMB handover. The one or more parameters may include a list of the technologies for which a make-before-break (MMB) handover is supported. For example, a parameter may use a specific bit structure wherein each bit is a Boolean representation of whether MMB handover is supported for a specific type of technology.
