    摘要: A method and device for performing media independent handover (MIH) in a wireless communication system. The method includes, and the apparatus is configured to, generate a higher layer handover message, send the higher layer handover message encapsulated in a lower level formatted communication, set a higher layer timing device for a timeout period in connection with the sending of the encapsulated higher layer handover message, and resend the higher layer handover message encapsulated in a lower level formatted communication unless a higher layer acknowledgement is received before expiration of the timeout period.

    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: 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 a media independent handover (MIH) session with an MIH application server using a session initiation protocol (SIP). The IMS client establishes a session for IP-based service, (e.g., voice over IP (VoIP)), with a communication peer using an SIP. MIH messages are exchanged for handover with the MIH application server over IP. After handover, the session is resumed. A serving call session control function (S-CSCF) triggers the MIH application server based on a string “MIH services” and a unique identifier included in an INVITE request. The IMS client may send a REFER request to the MIH application server after the handover to resume the session. Alternatively, the IMS client may send a RE-INVITE request to the MIH application server and the communication peer.

    摘要: A method for controlling behavior of lower layer links related to media independent handover (MIH) of a mobile user comprises sending a MIH link actions request primitive from a MIH User entity to a MIH function (MIHF) for requesting actions to be executed on a set of lower layer links to heterogeneous radio access technology (RAT) networks. The primitive includes parameters that indicate the requested actions and an execution time delay. Confirmation primitives are sent back the MIH User entity to convey the results of the execution attempts on the requested actions.
