  • Patent number: 10390231
    Abstract: A dynamic spectrum arbitrage (DSA) system includes a plurality of fixed wireless devices, a home eNodeB gateway (HGW) coupled to each of the plurality of fixed wireless devices, a dynamic spectrum controller (DSC) coupled to the HGW, and a dynamic spectrum policy controller (DPC) coupled to the DSC and a plurality of other DSCs. Each of the fixed wireless devices may be configured to use an enhanced location based service (eLBS) to dynamically determine its location (latitude, longitude and altitude) and the locations of other fixed wireless devices, and use the location information to determine whether the respective fixed wireless device may be included in a telecommunication resource lease. The fixed wireless devices may also monitor network conditions, generate congestion reports based on a result of the monitoring, and send the generated congestion reports to the HGW.

  • Patent number: 9860868
    Abstract: Methods, devices and systems for generating enhanced location information on or about a mobile device may include improved dead reckoning solutions in which the mobile device performs location determination calculations with the aid of network components or global positioning systems (GPS). The network aided location information may be provided to the processor and utilized in measuring the accuracy of sensor based location calculations. The mobile device may utilize local sensors to obtain a set of combined sensor output location information, which may seed execution of dead reckoning. To ensure that most accurate location information is provide to the enhanced location based service, the dead reckoning location information may be compared to a current best estimate. Results of the comparison may be passed to the enhanced location based service and the methods, systems, and devices may reiterate the location determination.

  • Patent number: 9843900
    Abstract: Methods, devices and systems for generating enhanced location information on or about a mobile device may include receiving (via a processor of the mobile device) location information from one or more of a sensor of the mobile device and an external system, generating (via the processor) a first waypoint based on the received location information, receiving network provided location information, generating a second waypoint based on the received network provided location information, retrieving dead reckoning location information, generating a third waypoint based on the received network provided location information, applying the first, second and third waypoints to a kalman filter to generate precise location information, and using the precise location information to provide the enhanced location based service.

  • Publication number: 20170295461
    Abstract: Method, systems and devices for determining for performing enhanced location based trilateration include receiving location information (e.g., waypoints) from one or more external devices, determining the validity of the received location information, performing normalization operations to normalize the received location information, assigning an overall ranking and a device-specific ranking to the location information, and storing the validated and normalized location information in memory. The enhanced location based trilateration may also include selecting four locations (e.g., waypoints) from the memory based on a combination of the overall ranking and the device-specific ranking, and generating a final location value or waypoint based on a result of applying the four selected waypoints to a kalman filter. The output of the kalman filter may also be reported and/or used as the device's current location.

  • Patent number: 9774999
    Abstract: Methods, devices and systems for generating enhanced location information on or about a mobile device. A mobile device may be configured to determine an initial location value, compute an initial location accuracy value, compare the initial location accuracy value to a threshold value, and establish a communications group with a plurality of transceivers in response to determining that the initial location accuracy value exceeds the threshold value. In response to establishing the communications group, the mobile device may receive location information from the transceivers, use the received location information to determine a trilateration position value, and compute a trilateration variance value. The mobile device may then determine a final location value based on a combination of the initial location value, initial location accuracy value, trilateration position value, and trilateration variance value, and use the final location value to provide an enhanced location based service.

  • Publication number: 20170207975
    Abstract: A dynamic spectrum arbitrage (DSA) system includes a dynamic spectrum policy controller (DPC) and a dynamic spectrum controller (DSC) that together dynamically manage the allocation and use of resources (e.g., spectrum resources) across different networks. The DSC component may include wired or wireless connections to eNodeBs, a policy and charging rules function (PCRF) component/server, and various other network components. The PCRF may be configured to receive eNodeB congestion state information from the eNodeB, information identifying wireless devices attached to the eNodeB, categorize each of the identified wireless devices into a category selected from a plurality of categories, select a subset of the identified wireless devices based on the category into which they are categorized, and perform congestion response operations on the selected wireless devices so as to reduce the congestion of the eNodeB.

  • Patent number: 9462574
    Abstract: A dynamic spectrum arbitrage (DSA) system may include a dynamic spectrum policy controller (DPC) and a dynamic spectrum controller (DSC) that together dynamically manage the allocation and use of resources (e.g., spectrum resources) across different networks. A dynamic spectrum arbitrage application part (DSAAP) protocol/component/module may allow, facilitate, support, or augment communications between the DSC and DPC so as to improve the efficiency and speed of the DSA system. The DSAAP may allow the DPC and/or DSC components to better pool resources across the different networks, better monitor traffic and resource usage in the various networks, to more efficiently communicate bids and bidding information, to quickly and efficiently register and deregister components, and better perform backoff operations.

  • Patent number: 9351112
    Abstract: Methods, devices and systems for generating enhanced location information on or about a mobile device may include hybrid lateration and trilateration solutions in which the mobile device performs location determination calculations with the aid of network components or global positioning systems (GPS). Mobile devices may automatically form groups based on proximity and/or may be grouped together via a network server. Mobile devices in a group may share computed location information and/or information collected from internal sensors with other grouped mobile devices. Information shared between grouped mobile devices may be used to enhance the location information computed on each mobile device. For example, each mobile device may supplement and/or augment previously computed location information based on the received location information and/or relative positions of other mobile devices in the same group. Each mobile device may also utilize local sensors to further enhance their location information.
