  • Publication number: 20120014311
    Abstract: Embodiments describe overlaying a broadcast multicast channel on top of a unicast network. Messages can be generated by protocols in a broadcast/multicast (BCMC) stack and tunneled through an IRTP of a serving access node. These messages can be transmitted on a BCMC channel and/or a unicast channel. Other messages can be generated by protocols in a unicast stack and tunneled to a B-IRTP of a BCMC Access node and transmitted on a BCMC channel to an access terminal.

  • Patent number: 8098662
    Abstract: Methods and apparatus for communicating between an access terminal (AT) and remote device via an access point (AP) are described. For communications over the air link, between an AP and an AT, a short address corresponding to the remote device is used for routing packets to/from the remote device. This conserves air link resources. However, for communicating between the AP and the remote device a longer address, e.g., a full IP address corresponding to the remote device, is used. The AT converts between the long and short addresses as information, e.g., packets, is communicated between the remote device and the AT. The long address may be, for example, an IP address corresponding to the remote device used to route packets through a Layer 2 tunnel between the remote device and the AP. In some embodiments the remote device is a remote access point.

  • Patent number: 8099096
    Abstract: Methods and apparatus related to management of active connections between an access terminal and access points are described. An access terminal maintains and manages active set information. The active set information identifies a set of access points with which the access terminal has an active connection. In some embodiments, the active set information includes allocated resources assigned to the access terminal corresponding to the different access points in the active set. Layer 2 Transport Tunneling is used, in various embodiments, to communicate connection request and/or connection response information, between access points. In some embodiments, the access terminal optionally assists in coordinating MAC resources allocated to the access terminal by different access points.

  • Patent number: 8078135
    Abstract: A method and apparatus for transmitting and processing a QuickChannelInfo block is described. A plurality of superframe indices are determined, and a QuickChannelInfo block is transmitted to an access terminal in the superframe with an odd superframe index. The contents of the QuickChannelInfo block are changed in accordance with a QuickChannelInfo Validity field of the QuickChannelInfo block. It is determined if a multi-carrier mode of a protocol is MultiCarrierOn. The QuickChannelInfo block is transmitted on each carrier of the protocol. The QuickChannelInfo block is transmitted to the access terminal over a communication link. The QuickChannelInfo block is processed after the QuickChannelInfo block is received at the access terminal over the communication link.

  • Patent number: 8068835
    Abstract: Systems and methods are provided for processing wireless signal components for a mobile wireless access broadband service. This can include processes for measuring signal strength of an alternative frequency by tuning away from an existing frequency associated with an existing communications path. Such processes allow determining if the alternative frequency supports a subsequent communications path in a mobile broadband wireless application. Upon the determination, the process can automatically select the subsequent communications path based in part on the measured signal strength.

  • Patent number: 8059595
    Abstract: In a communication system in which a gateway entity is linked to a plurality of infrastructure entities which in turn are operable to communicate with an access terminal, the access terminal needs first to establish a data attachment point (DAP) with one of the infrastructure entities. Handoff of the DAP from one infrastructure entity to another infrastructure entity is initiated by the access terminal. The access terminal weighs factors such as the link conditions with the various infrastructure entities, the time since the last DAP handoff, and time duration communicating with the current infrastructure entity before proceeding with the DAP handoff.

  • Publication number: 20110267943
    Abstract: Certain aspects of the present disclosure provide techniques and apparatuses for implementing a static mapping between a Uu radio bearer and a Un radio bearer based on quality of service (QoS) class identifier (QCI). According to certain aspects, a donor base station perform a Un bearer management procedure to establish a Un radio bearer that does not utilize TFT such that the QCI-based static Uu-Un bearer mapping does not interfere with existing traffic mappings that utilize Service Data Flow (SDF) filters. In addition, the QCI-based static Uu-Un bearer mapping can satisfy QoS requirement(s) for bearer handling without requiring modification to wireless protocols or associated specification(s) of telecommunication networks with relay nodes.

  • Publication number: 20110249610
    Abstract: Methods and apparatuses are provided that facilitate compressing packet headers for communicating among access points. An access point can advertise compression profiles to one or more disparate access points, and the one or more disparate access points can select at least one compression profile for compressing/decompressing packets related to the one or more disparate access points and/or devices communicating therewith. The one or more disparate access points can notify the access point of the selected compression profile, a compression context identifier, and/or static data related to identifying associated packets. In this regard, the access point can compress packets that have the associated static data according to the compression profile and compression context identifier. Similarly, the access point can decompress packets from the one or more disparate access points based on the compression context identifier.
