  • Publication number: 20120144062
    Abstract: Systems, methods, and instrumentalities are disclosed that provide coordination between MPTCP and mobile IP (MIP). An MPTCP session may be established between a mobile node and a correspondent node. MIP and simple IP subflows may be established in the MPTCP session. The mobile node may activate MIP and establish a first subflow via MIP. The first subflow may be associated with a first path that may be routed through a first home agent. The mobile node may deactivate MIP and establish a second subflow via simple internet protocol (IP). The second subflow may be associated with a second path that is not routed through a home agent.

  • Publication number: 20120140756
    Abstract: A method and wireless communication system may be used for transferring management information. An access point (AP) may transmit a management information base (MIB) information request including a category field and an action details field to a wireless transmit/receive (WTRU). In response to receiving the information request, the WTRU may determine whether or not to provide management information to the AP. When the WTRU provides management information to the AP, the WTRU may compile management information stored in a MIB located in the WTRU and transmit a MIB information report to the AP. The MIB may list a plurality of tables containing information associated with radio resource management (RRM) and at least one table containing physical layer measurements. The AP may include a MIB for storing MIB information of the WTRU. The AP may transmit the stored MIB information of the WTRU in response to a request.

  • Patent number: 8139521
    Abstract: A wireless communications network includes access points and wireless nodes. Each access point and each wireless node has a respective authentication token and address associated therewith. The access points and wireless nodes communicate using packets, where each packet includes an authentication token, an origination address and a destination address. During the communications, the access points read and store the respective authentication tokens and origination addresses in the packets wirelessly transmitted from the wireless nodes for defining an allowed wireless node list. Likewise, each wireless node reads and stores the respective authentication tokens and origination addresses wirelessly transmitted from the access points for defining an allowed access point list. The wireless nodes and access points do not associate with an attacker if both an authentication token and an address associated with the attacker are not on the respective allowed access point and wireless node lists.

  • Patent number: 8140078
    Abstract: A method for operating a wireless mobile device moving through different types of networks includes storing within the wireless mobile device a type of network associated with a respective access node as the wireless mobile device moves through the different types of networks. A type of connectivity available for each access node is stored within the wireless mobile device, as well as location of each access node. The wireless mobile device is operated with a current access node corresponding to one type of network based on a current location of the wireless mobile device. Handoff is initiated by the wireless mobile device from the current access node to another access node corresponding to a different type of network based on movement of the wireless mobile device.

  • Patent number: 8134978
    Abstract: A radio interface layer media independent handover (RIL MIH) client functionality enables transparent inter-system handover of a wireless transmit/receive unit (WTRU) between different radio access technologies (RATs), without user intervention. The RIL MIH client interacts with RIL drivers and proxies, informs the RIL proxies of the handover status, then the proxies interact with a new driver in use. A WTRU is modified to add MIH functionality to a telephony server to support inter-system handover.

  • Patent number: 8134955
    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.

  • Patent number: 8121098
    Abstract: A method and wireless communication system for transferring management information. The system includes at least one access point (AP) including a first management entity and a second management entity, and at least one wireless transmit/receive unit (WTRU) including a third management entity and a fourth management entity. The AP transmits a management information base (MIB) information request action frame including a category field and an action details field to the WTRU. In response to receiving the information request action frame, the WTRU determines whether or not to provide management information to the AP. When the WTRU provides management information to the AP, the WTRU compiles management information stored in a MIB located in the WTRU and transmits a MIB information report action frame to the AP. The MIB lists a plurality of tables containing information associated with radio resource management (RRM) and at least one table containing physical layer measurements.
