  • Patent number: 9980285
    Abstract: Attachment data collected by a set of femto access points (FAPs) is utilized to localize, predict, and/or weight potential wireless communication traffic within and between areas. Moreover, the attachment data can be indicative of user equipment (UE) density/traffic within coverage areas of respective femtocells. The attachment data can be consolidated and analyzed to identify location and motion of a UE “swarm”. Moreover an automatic cell planning (ACP) component can be employed to utilize the attachment data for determining an optimal macro site and optimal antenna setting(s) that facilitate steering/tuning the macro antenna beam to focus upon the swarm area. In addition, the ACP component can facilitate reconfiguration of the macro antenna beam as reported swarm concentrations shift between the FAPs.

  • Patent number: 9980211
    Abstract: Inter-carrier scanning is triggered in a mobile device based at least in part on location thereof. Femto access point (AP) that can serve the mobile device can determine location through cell or sector identifier that is extracted via scan(s) of macro wireless environment of the femto AP. Femto AP can rank extracted sector identifier(s) and establish home macro sector (HMS) identifier(s), and also can generate scanning requirements for idle-mode scan(s) by a mobile device that operates in a HMS and is authorized to access wireless coverage through the femto AP. Scanning requirement(s) can force periodic inter-carrier measurements of a HMS wireless environment, and establish HMS-specific radio link quality threshold(s). Wireless network can receive at least one of HMS identifier(s) and scanning requirement(s) and deliver same to mobile device(s) authorized to exploit wireless coverage through femto AP associated with the HMS ID(s) and the scanning requirement(s).

  • Patent number: 9980177
    Abstract: Detection of an unbalanced network load and redistribution of network traffic to balance the network load is provided herein. Load balancing across different radios in the same sector of a cell site can be facilitated through detection of the unbalance network load and changes to one or more parameters can be made to rebalance the network load. After radios within a sector are more evenly balanced, network load balancing across sectors can be facilitated. The balancing can be performed to improve system performance, reduce a dropped call rate, as well as to achieve other benefits that can provide an improved user experience as compared to systems that do not attempt to balance the network load.

  • Patent number: 9972145
    Abstract: Concepts and technologies are disclosed herein for spoofing bone conduction signals. According to one aspect, a device can compare a first unique body signature associated with a first user to a second unique body signature associated with a second user to determine a first unique effect of a first body of the first user on a signal and a second unique effect of a second body of the second user on the signal. The device can generate an authentication signal based upon the first unique effect and the second unique effect to include signal characteristics that, after propagating through the first body of the first user, are representative of the second unique body signature. The device can transmit the authentication signal through the first body of the first user to an authentication device that authenticates the first user on behalf of the second user.

  • Patent number: 9973492
    Abstract: A mobile secure agent on a wireless device executes one or more authenticated data collection profiles provisioned by a private profile producer. Each data package can only be transmitted to a collector certificated by the same private profile producer. Update profiles are signed and provisioned through a tunnel initiated from the mobile secure agent. A Certificate Authority provides libraries, anchors, and certificates in a key management message module to each mobile secure agent which enables revocation and replacement of certificates. Data stored in this way on a wireless device may only be transmitted in encrypted form to an authenticated destination.

  • Patent number: 9972309
    Abstract: Systems, methods, and computer-readable storage devices for generating speech using a presentation style specific to a user, and in particular the user's social group. Systems configured according to this disclosure can then use the resulting, personalized, text and/or speech in a spoken dialog or presentation system to communicate with the user. For example, a system practicing the disclosed method can receive speech from a user, identify the user, and respond to the received speech by applying a personalized natural language generation model. The personalized natural language generation model provides communications which can be specific to the identified user.

  • Patent number: 9973633
    Abstract: A pre-distortion system for improved mobile device communications via cancellation of nonlinear distortion is disclosed. The pre-distortion system may transmit an acoustic signal from a network to a device, wherein the acoustic signal includes a linear signal and a nonlinear cancellation signal that cancels at least a portion of nonlinear distortions created once a loudspeaker in the device emits the linear signal. Thus, when a loudspeaker of a mobile device is operating and nonlinear distortions are generated by the loudspeaker or adjacent components of the mobile device in close proximity to the loudspeaker, the pre-distortion system may create one or more nonlinear cancellation signals in the network. The nonlinear cancellation signal may be combined with the linear signal sent to the loudspeaker to cancel the nonlinear distortion signal created by the loudspeaker emitting acoustic sounds from the linear signal. Thus, the nonlinear cancellation signal becomes a pre-distortion signal.

  • Patent number: 9973881
    Abstract: Information is acquired from a geographically-distributed sensor network using a scalable wireless geocast protocol. Geographically distributed networks of unattended sensors are placed at desired locations to collect various types of information, such as, for example, environmental parameters, temperature, humidity, rainfall, heat signatures, video, audio, seismic activity, and/or wind conditions. To acquire information, a query is provided to the geographic area at which the sensors are located utilizing the geocast protocol. Delivery of the query is based on a physical location of a region in which a sensor network is located, the type of information being queried, and/or temporal conditions. Each sensor that receives a query determines if all requirements/conditions are satisfied. If so, the query is accepted and processed by the recipient sensor, and responded to accordingly. Responses to queries are provided via the geocast protocol.

  • Patent number: 9973964
    Abstract: A wireless data access system is provided to ameliorate bursty traffic occurring in a radio communications link such as a WiFi, WiMAX, 3G or cellular telephone link to a wireless network access device. A data traffic event is detected relating to traffic in the link. The traffic event may be a traffic burst exceeding a predetermined threshold. Based on detecting the data traffic event, a free-space optical communications link is established to the network access device to handle the traffic burst. The established radio link may be used to set-up and coordinate the free-space optical link.

  • Patent number: 9973940
    Abstract: Aspects of the subject disclosure may include, for example, a guided wave launcher generates, in response to an output RF signal, a guided electromagnetic wave along a surface of a transmission medium, wherein the guided electromagnetic wave propagates along the surface of the transmission medium without requiring an electrical return path, and wherein the guided electromagnetic wave has a non-optical carrier frequency. A mismatch probe generates a mismatch signal based on the output RF signal, wherein the mismatch signal indicates an impedance mismatch of the guided wave launcher. A controller generates one or more control signals in response to the mismatch signal, wherein the one or more control signals adjust one or more adjustable circuit elements of an impedance matching circuit, wherein adjustment of the one or more adjustable circuit elements facilitates reducing the impedance mismatch of the guided wave launcher. Other embodiments are disclosed.
