Abstract: 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 (e.g. MIH SWITCH, MIH SCAN) from a MIH User entity to a MIH function (MIHF) for requesting actions to be executed on a set (a group, multiple, several) 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, IEEE 802.21 standard. (Comprising a result code).

Abstract: 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.

Abstract: 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 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.

Abstract: 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.

Abstract: 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.

Abstract translation: 本发明修改了由IEEE 802.21标准定义的现有媒体独立切换（MIH）功能（MIHF）帧格式。 在一个实施例中，MIHF帧的可变负载被修改以通过将MIHF标识（ID）字段和会话ID字段定义为MIHF固定头部中的固定字段来消除MIHF可变头。 因此，MIHF可变负载仅由MIHF有效载荷组成。 在另一个实施例中，诸如信息元素（IE），头部或诸如命令或事件的MIH服务数据之类的字段由类型字段，长度字段和值字段（TLV）表示。 值字段的长度恰好是128个八位位组，长度字段只占用一个八位字节。
