摘要:
A Media Independent Handover (MIH) server communicates with nodes in a cellular network to perform handover of a wireless transmit/receive unit (WTRU) in the event of an incoming circuit-switched (CS) call. A Gateway Mobile Switching Center (GMSC) and/or Home Location Register (HLR) receive an indication of an incoming call, and may communicate with the MIH server. A determination is made regarding whether the WTRU is active in the cellular network. When required, the MIH server initiates an MIH handover of the WTRU to the cellular network. The WTRU hands over to the cellular network and receives the call. Additionally, an MIH server and a HLR communicate location information associated with a WTRU. The location information may be used by the MIH server and HLR to perform their respective MIH and HLR functionality, and/or to handover the WTRU to a cellular network in the event of an incoming CS call.

A wireless transmit/receive unit (WTRU) includes a mobility management function and a multihoming function. The mobility management function may implement the Media Independent Handover (MIH) protocol and the multihoming function may implement the Shim6 protocol. The mobility management function may communicate link status information to the multihoming function. Based on the link status information, the multihoming function may accelerate or decelerate a link failure detection procedure, may modify a list of possible paths for consideration for a path exploration procedure, and/or may determine to initiate a path exploration procedure. The multihoming function may communicate to the mobility management function that additional communications resources are required. In response, the mobility management function may activate an inactive radio interface. Subsequent path exploration procedures may include the exploration of paths that may be established over the activated radio interface.
摘要:
A method and an apparatus for a proxy mobile Internet protocol (PMIP) supporting a dedicated multicast local mobility anchor (LMA) and mobile access gateway (MAG) is provided. The LMA assigns an Internet Protocol (IP) address to a wireless transmit receive unit (WTRU) that processes the IP address and sends a router solicitation message to a serving MAG. A WTRU is disclosed to receive a first IP address that is for unicast service and a second IP address that is for multicast services. Generally, the method and apparatus proposes architecture, interfaces, and procedures to enable multicast mobility using Proxy Mobile IP. More specifically operations of aggregated PMIP tunnels for multicast services are described. Multicast mobility is enabled when mobile nodes move from one MAG to another MAG, intra-LMA, and inter-LMA. And, Multicast mobility is enabled between bidirectional network and downlink only multicast network in a hybrid network.

A method and apparatus are disclosed for communication access technology management. A wireless transmit/receive unit (WTRU) may evaluate end-to-end connection performance by sending a connection ECHO message and receiving a connection ECHO response. The connection performance may be evaluated for a connection including multiple transmission paths, and for multiple connections. The WTRU may establish or modify a multihoming communication session with a mobility server using a plurality of connections. Each connection may be established using a different interface.

A method and apparatus for use in a network storage control peer (NSCP) supporting peer to peer (P2P) operation are disclosed. The method includes receiving information from a tracker, wherein the information includes swarm stats, selecting and joining a swarm based on the received information, receiving a first stat report from the tracker, wherein the stat report includes additional swarm stats, determining whether to upload information to an ingestion gateway based on the received first stat report, transmitting an upload request message to the ingestion gateway, receiving an upload response from the ingestion gateway, and transmitting a second stat report to the tracker; wherein the second stat report includes a uniform resource identifier (URI) for the uploaded information.
摘要:
A method and apparatus may be used for exchanging measurements in wireless communications. The apparatus may receive a request. The request may be a measurement request, and may include a request for a measurement of a parameter. The apparatus may transmit a report. The report may be a measurement report, and may include the requested measurement of a parameter. The apparatus may store the requested measurement of the parameter in a management information base (MIB).
