  • Publication number: 20130070629
    Abstract: A system and method of increasing data throughput in a wireless communications network between a base station (BS) and one or more mobile stations (MS) includes establishing a service flow (SF) and initially enabling a hybrid automated repeat request (HARQ) protocol; determining, at a particular time, the measure of quality of the communications channel; comparing the determined measure of quality with a predetermined channel quality threshold; and selectively disabling the HARQ protocol based upon a first comparison result while continuing the SF between the BS and MS. In other aspects, after selectively disabling the HARQ protocol, the method further includes determining that the time-varying measure of quality of the communications channel has deteriorated below the predetermined channel quality threshold; and selectively re-enabling the HARQ protocol in the established SF.

  • Patent number: 8396039
    Abstract: Systems and methods of operating multimode 3G/4G communications devices in an overlapping 3G/4G coverage area (e.g., WiMAX or LTE/CDMA EvDO) include determining if a number associated with temporarily-disabled sectors of an available sector set of the multimode device while the device is operational with a 3G base station is at least equal to a threshold number. If the number is at least equal to the threshold number, a scan for a sector in the 4G network to handover the operation of the multimode device from the 3G base station associated with the 3G coverage to a 4G base station associated with the 4G coverage is initiated. A scan for a fixed period of time for a new available sector in the 3G network to be added in the available sector set may be initiated; and, if a new available sector is added to the sector set, it may be redetermined if the number associated with the temporarily-disabled sectors is at least equal to the threshold number, before initiating the scan for a sector in the 4G network.

  • Patent number: 8370872
    Abstract: Systems, methods and media are provided for presenting a group of available broadcast channels utilizing a wireless network upon initiation of a channel-viewing graphical user interface (GUI). The group comprises channels that can be broadcast most efficiently to the mobile device. After initiating the channel-viewing GUI on the mobile device, requests are communicated to elements on the network to retrieve lists of currently broadcast channels in the area and currently viewed channels throughout the wireless network. A list also is retrieved of recently viewed channels on the mobile device. At least a portion of each list is then presented on the channel-viewing GUI. The lists can be sent by a first video media proxy (VMP) server and a broadcast management server (BMS).

  • Patent number: 8326305
    Abstract: The present invention relates to systems and methods for selectively pre-registering a data path for a mobile station. In an embodiment, a serving base station receives a mobile-originated handoff-request message from a mobile station, wherein the mobile-originated handoff-request message identifies one or more target base stations. The serving base station then responsively determines whether to instruct each respective target base station to pre-register a data path for the mobile station. The serving base station then sends a respective serving-to-target handoff-request message to each identified target base station, indicating whether the serving base station is instructing that target base station to pre-register a data path for the mobile station.

  • Patent number: 8311573
    Abstract: A first wireless device associated with a first profile is communicated with using a first transmitted power. A second wireless device associated with a second profile is communicated with using a second transmitted power. A third transmitted power is determined. The third transmitted power is associated with the first wireless device receiving data using a target modulation and coding scheme. A maximum transmitted power is determined to be exceeded if the third transmitted power is used to communicate with the first wireless device. The second wireless device is communicated with using a fourth transmitted power. The fourth transmitted power allows the third transmitted power to be used to communicate with the first wireless device without exceeding the maximum transmitted power.

  • Publication number: 20120275372
    Abstract: A media service controller controls how one or more base stations transmit media content from one or more media servers to mobile stations. The media service controller may control whether a mobile station receives media content via a unicast or a multicast connection, e.g., based on a predefined schedule and/or on whether other mobile stations served by the same base station are receiving the same media content. The media service controller may provide a content discovery service through which a first media server may determine whether other media servers are providing the same media content. The media service controller may facilitate changing a source of media content received by a mobile station, e.g., by changing the source from a first media server to a second media server when the mobile station moves from an area associated with the first media server to an area associated with the second media server.

  • Publication number: 20120275388
    Abstract: A system and method for adaptive control of an averaging parameter in a communications network may include an averaging parameter adaptive control module (APAC) that is associated with a base station and that includes one or more processors configured to generate a first averaging parameter that is transmitted by the base station to a mobile station communicating with the base station. The mobile station may use the first averaging parameter to generate first channel condition information that indicates a condition of a communication channel. First feedback information including the first channel condition information may be received at the base station. The APAC may generate a second averaging parameter using the first averaging parameter and the first feedback information and may transmit the second averaging parameter from the base station to the mobile station, thereby adaptively controlling the second averaging parameter based on the first feedback information.
