    Abstract: Wireless access points within a GPS-Unavailable environment can provide location services to user equipment devices within the environment provided that the access points are aware of their precise locations. In order to calibrate the locations of the wireless access points, a user equipment is moved to specific locations within the environment. At each of those locations, the user equipment transmits calibration signals that include the transmission location as well as a timestamp of the transmission time. Upon receipt by the access points, these signals are timestamped with a reception timestamp by a clock that is synchronized with the clock of the user equipment. After accumulating sufficient calibration information from a sufficient number of calibration locations, the access points can accurately determine their locations using trigonometric and other functions.

    CPC classification number: H04W36/245

    Abstract: Systems and methods for adaptive access and handover configuration based on historical data are provided. Access and handover decisions are optimized in a multiple radio access technology environment using historical data associated with network performance. Future needs for access and handovers are predicted using historical data associated with the user and historical data associated with network performance. Performance metrics are received periodically or continuously from nodes in one or more networks at a centralized controller. The centralized multi RAT controller correlates these performance metrics and determines predicted handovers for a user device. Preparations for the predicted handovers can then be made prior to the handover event.
