  • Patent number: 9750050
    Abstract: Access priority for wireless devices located in an area in which radiofrequency (RF) coverage areas of a first wireless access point and a second wireless access point overlap is controlled by coordinating operation of the first wireless access point and the second wireless access point. The wireless devices access a common RF channel via a collision sense multiple access/collision avoidance mechanism. The probability of accessing the RF channel may be varied by adjusting the length of interframe spacings and the length of contention windows. The length of the interframe spacings and the length of the contention windows associated with the first access point and associated with the second access point are configured such that the probability of wireless devices associated with the first wireless access point accessing the RF channel is greater than the probability of wireless devices associated with the second wireless access point accessing the RF channel.

  • Patent number: 9749234
    Abstract: Signaling-less call setup and teardown by employing observed Quality of Experience (QoE) and resource demands. A system provides an environment for supersonic treatment of observed QoE and Quality of Service (QoS) demands for mobile applications. Specifically, a monitoring component is employed to determine session state information associated with a traffic flow, which includes observed QoE and resource demand data. The session state information is stored in a shared memory location and can be analyzed to modify and/or create a network policy for the traffic flow. The network policy is applied to one or more traffic flows to minimize signaling exchanges between a communication network and a mobile station.

  • Publication number: 20170244670
    Abstract: Concepts and technologies disclosed herein are directed to behavior-based filters for signaling system number 7 (“SS7”) networks. According to one embodiment disclosed herein, a behavior-based SS7 filter executed by a processor can receive SS7 traffic. The behavior-based SS7 filter can determine a behavioral characteristic from the SS7 traffic and can compare a behavior of the SS7 traffic, based upon the behavior characteristic, to a behavior profile. The behavior-based SS7 filter also can determine whether the behavior of the SS7 traffic fits within a tolerance threshold of the behavior profile. If the SS7 traffic fits within the tolerance threshold, the behavior-based SS7 filter can instruct a signal transfer point (“STP”) to which the SS7 traffic is directed to allow routing of the SS7 traffic. If, however, the SS7 traffic does not fit within the tolerance threshold, the behavior-based SS7 filter can instruct the STP to deny routing of the SS7 traffic.

The handset agent can be installed on the mobile device and can upload to an internet server the coordinates captured by the GPS receiver along with the observed time differences. The observed time differences and the location of the mobile device can be used to solve for reference time differences to calibrate unsynchronized macrocells. The reference time difference can be used to solve for the location of other mobile devices if the observed time differences between that mobile device and the macrocells are known. The solution can include receiving measurement reports from many mobile devices to obtain averaged observed time differences at a reference location to achieve more accurate reference time differences.

    Abstract: A method of increasing resolution of an image includes generating vector contours associated with a first image and scaling the vector contours to a second resolution. The first image has a first resolution, and the second resolution is greater than the first resolution. The vector contours are rendered to generate a guiding image at the second resolution, and a second image is generated from the first image based on the guiding image, by using joint upsampling. The second image is generated at the second resolution. The vector contours can be generated by bitmap tracing binary images at different quantization levels.

  • Patent number: 9740284
    Abstract: A system for adjusting content display orientation on a screen is disclosed. The system may include a processor that may detect both eyes and a body part of a user that is proximal to one or more of the user's eyes. The system may then determine an eye gaze plane based on the positions of the first and second eyes of the user. The eye gaze plane may be determined by identifying a first line of sight extending from the first eye and a second line of sight extending from the second eye. Additionally, the eye gaze plane may bisect a center of the first eye and a center of the second eye of the user. Once the eye gaze plane is determined, the system may adjust the orientation of content displayed on a display device based on the eye gaze plane and on the position of the body part.

  • Patent number: 9743263
    Abstract: Security systems are warned of earthquakes, tornadoes, and other natural disasters. When an early warning system detects a natural disaster, the early warning system alerts a central server. The early warning system alerts the central server to the natural event and its associated geographic area. The central server may then consult a database and determine the security systems operating in a vicinity of the geographic area experiencing the natural event. The central server may thus warn the security systems of the natural event. The security systems may then implement pre-programmed procedures to protect life and property during earthquakes, tornadoes, and other natural disasters.

  • Patent number: 9743300
    Abstract: Coverage and usage-based limitations to a wireless communications network can be estimated by monitoring network performance during a periods in which the network is relatively busy and relatively non-busy. For example, differences in distributions of bit error rates for calls in such time periods can be used to assess whether network limitations are associated with reduced-coverage zones or are usage-based. Such estimates can be used to target specific network features that limit network performance.
