  • Patent number: 8457075
    Abstract: Systems and methods are provided for processing wireless signal components for a mobile wireless access broadband service. This can include processes for defining a protocol that controls whether to invoke a tune away component to determine an alternative wireless communications path. This can include defining one or more tune away parameters for the tune away component. The process can then automatically select the alternative wireless communications path based in part on the tune away procedure and at least one of the tune away parameters.

  • Patent number: 8442060
    Abstract: Signaling-only access may be established with an access node under certain circumstances such as, for example, upon determining that a node is not authorized for data access at the access node. A node that is not authorized for data access at an access node may still be paged by the access node through the use of signaling-only access. In this way, transmissions by the access node may not interfere with the reception of pages at the node. A first node may be selected for providing paging while a second node is selected for access under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.

  • Patent number: 8416751
    Abstract: Methods and apparatus for communicating between an access terminal (AT) and a device serving the AT by way of an Access Point (AP) are described. In accordance with one feature serving devices may be assigned specific addresses which are interpreted based on the source of the communication, e.g., MAC packet, in which the address is used. Such addresses may be interpreted as being of a different type than other addresses which can be interpreted and/or used without taking into account the identity of the sender. In some embodiments Session Controllers and/or Internet Attachment Points (IAPs) are identified with such addresses. The address value is the same for one or more ATs but is interpreted at an AP receiving such the IAP address based on information corresponding to the AT which sent the packet including the IAP or Session Controller address.

  • Patent number: 8401068
    Abstract: Systems and methodologies are described that facilitate assigning TEIDs, or portions thereof, to UEs or other devices during network attachment and/or dedicated bearer activation using one or more cell relays. Relay eNBs can request bearer establishment from a UE, which can be based on receiving an attach accept from an upstream node during attachment for the UE, receiving a bearer setup request from the upstream node, and/or the like. Once a bearer establishment response is received from the UE, the relay eNBs can store a TEID relating to the bearer. This can be a TEID that is at least partially received in the attach accept or bearer setup message, generated for the UE upon receiving the bearer establishment response, and/or the like. The TEID, or portion thereof, can be utilized for subsequent packet routing to the UE through one or more cell relays.

  • Patent number: 8401555
    Abstract: Described herein are mechanisms and methods that facilitate generation of receiver status message (e.g., acknowledgments and/or negative acknowledgments) before, during, and after a handoff of an access terminal (user equipment) from a first transceiver module to a second transceiver module. A network module can generate receiver status messages during a handoff and informs a target transceiver module of when it can begin to generate receiver status messages for data received from an access terminal.

  • Publication number: 20130028118
    Abstract: A wireless communication network may provide services, e.g., multimedia services, in unicast and broadcast modes, and the mode of providing a service may depend on a level of demand. In response to changing demand for a service the network may determine that service should transition from one mode to the other, and the network, may signal such a transition to one or more terminals subscribing to the service.

  • Patent number: 8363583
    Abstract: A channel access scheme is provided for a pulse-based ultra-wide band network. Here, concurrent ultra-wide band channels may be established through the use of a pulse division multiple access scheme. An access scheme may employ different states each of which may be associated with different channel parameter state information and/or different duty cycles. For example, a channel access scheme may employ an inactive state, an idle state, a connected state, and a streaming state. Multiple logical channels may be defined for a given ultra-wide band channel via, for example, pulse division multiplexing.

  • Patent number: 8355336
    Abstract: Methods and apparatus for formatting headers for data packets within a communication frame for use in a wireless communication system are presented. Formatting headers includes determining the size of a wireless communication frame, and formatting the payloads and associated headers within the communication frame according to the determined size. This formatting includes placing headers at the beginning of the frame before the data packets corresponding to the headers to optimize processing of the headers at a receiver. Formatting may also include formatting the headers according to a first format within the frame when the determined frame size is below a predetermined size to optimize the size of the headers, and formatting according to a second format within the frame size of the data packet is equal to or greater than the predetermined size to optimize processing for frames having large data packets.

  • Patent number: 8335202
    Abstract: Systems and methodologies are described that facilitate enhancing acquisition and handoff in a wireless network deployment by leveraging primary pilots and secondary pilots. The deployment can support more than one frequency band for operation, yet a mobile device can receive signals on one frequency band at a given time. Thus, a base station can transmit primary pilot(s) over frequency band(s) associated with operating data channel(s) as well as secondary pilot(s) over frequency band(s) that lack data channel(s) for the base station. Moreover, the base station can convey information that indicates to a mobile device whether each pilot is primary or secondary. Further, the mobile device can employ knowledge of pilot type (e.g., primary or secondary) as well as signal strength to effectuate handoff decisions; thus, disruptions in communication can be mitigated.

  • Patent number: 8284660
    Abstract: Scheduling real-time Quality of Service (QoS) data flows in a large-scale wireless communications system uses credit allocation to active QoS flows based on quality-of-service weights, and the credits are measured in dimensionless units of air interface slot capacity. Scheduling addresses inactive QoS flows with no data pending for transmission that may accumulate up to a burst credits limit based upon a fair share of all credits that would be allocated in a 100% busy system. Intermittent flows such as echo requests or keyboard input can thereby get immediate service by using their burst credits. The flow with the highest credit accumulation is serviced first and may use up to a full time slot (or system quanta) of air interface time reducing header encapsulation overhead when payload sizes (and spectral efficiency) are low. Additive and multiplicative aspects age the negative credits back to zero whenever a flow overspends its credit allocation.

  • Publication number: 20120252355
    Abstract: Methods and apparatuses are provided that include handing over relays in wireless networks. Handover request messages for a relay and related user equipment (UE) can be grouped to lessen signaling requirements for handover. Moreover, identifiers can be communicated in the messages to optimize bearer establishment at a target base station to which the relay and related devices are handed over. Also, handover exception cases can occur, which can be handled by the relay and source and target base stations, such as bearer rejection at the target base station, handover failure for one or more devices or the relay, and/or the like. Further, handover of a relay can occur between base stations that house one or more network gateways for the relay, or where the gateways are centralized and accessible by the source and target base stations, where each scenario can include different exception handling.
