    Abstract: Techniques for locating a mobile device using a time distance of arrival (TDOA) method with disturbance scrutiny are provided. In an aspect, for respective combinations of three base station devices of a number of base station devices greater than or equal to three, intersections in hyperbolic curves, generated using a closed form function with input values based on differences of distances from the device to pairs of base station devices of the respective combinations of three base station devices, are determined. The intersection points are then tested for robustness against measurement errors associated with the input values and a subset of the intersection points that are associated with a degree of resistance to the measurement errors are selected to estimate a location of the device.

  • Patent number: 10142887
    Abstract: A scalable virtualized network core is provided to allow for incrementally adjusting network resources in response to changing demand, and for improved flexibility in network management and control. The scalable virtualized network core provides a cloud evolved packet core that has virtual machines performing the functions of the individual server elements. As demand for network resources changes, additional virtual machines can be brought online or virtual machines can be terminated to efficiently address the demand. An abstraction agent can be provided to facilitate the physical to logical connections so that to the perspective of elements in a radio access network, no changes have been made. The abstraction agent also facilitates network control and management of the virtual machines.
