  • Patent number: 7957277
    Abstract: A wireless communication system including a mesh network having a plurality of mesh points (MPs), a plurality of wireless transmit/receive units (WTRUs), extra-mesh local area network (LAN) resources, and an external network is disclosed. When one of the MPs receives a packet, a determination is made as to whether the received packet is destined to another MP belonging to the same mesh network, (or to a WTRU served by another MP), and, if so, a determination is made as to whether there are at least two mesh portals in the mesh network that provide access to the external network via the extra-mesh LAN resources. The packet is routed according to an intra-mesh routing algorithm if there are less than two mesh portals in the mesh network. Otherwise, a determination is made as to whether an extra-mesh routing algorithm or an intra-mesh routing algorithm should be used.

  • Publication number: 20110110286
    Abstract: 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.

  • Publication number: 20110064050
    Abstract: A wireless transmit/receive unit (WTRU) may receive a broadcast service via a broadcast system. The broadcast service may be handed over from the broadcast system to a second broadcast system, and the WTRU may receive the broadcast service via the second broadcast system. The WTRU and/or the broadcast system may change broadcast service configuration parameters (such as video encapsulation format, video codec, frame rate, audio codec) to receive and/or display broadcast service data received via the second broadcast system. Additionally, a WTRU may receive a broadcast service via a broadcast system that includes more than one broadcast transmission network. The broadcast service may be handed over from a first broadcast transmission network in the broadcast system to a second broadcast transmission network in the broadcast system. The WTRU may change broadcast service configuration parameters to receive and/or display broadcast service data received via the second broadcast transmission network.

  • Publication number: 20110019104
    Abstract: Disclosed herein are methods and apparatus for the communication of wireless data using diverse radio access technologies (RATs) in Television Band (TVBD) frequencies. An architecture for communicating wireless data in TVBD frequencies may include one or more network nodes that perform functions related to the coordination of channel quieting across multiple diverse RATs. Channel quieting may be performed across multiple diverse RATs by using temporary channel reassignments, by aggregating wireless transmit/receive units (WTRUs) that use a particular RAT onto the same channel, and/or via other techniques.
