  • Patent number: 10064099
    Abstract: Aspects of the subject disclosure may include, for example, a non-transitory machine-readable storage medium comprising executable instructions that, when executed by a processing system including a processor, perform operations comprising: identifying a first plurality of cells as a controlled group of cells; determining, for each cell of the controlled group of cells, an average number of allocated physical resource blocks; determining, for each cell of the controlled group of cells, a total number of physical resource blocks available to carry payload traffic; determining, for each cell of the controlled group of cells, a metric equal to: (a) the average number of allocated physical resource blocks of the cell divided by (b) the total number of physical resource blocks of the cell available to carry payload traffic; and performing a load balancing of the controlled group of cells based upon the metric. Other embodiments are disclosed.

  • Publication number: 20180227876
    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: 9187976
    Abstract: Apparatus and methods for managing cementing operations are provided. An example method includes connecting a cementing adapter atop a casing head itself positioned atop a surface casing landed within a conductor pipe, connecting a drilling adapter atop the cementing adapter, connecting a blowout preventer to the drilling adapter, and drilling for and running production casing. The method also includes positioning a casing hanger at least partially within a bore of the cementing adapter to be immobilized therein to retain back pressure of cement within an annulus located between the production casing and the surface casing, cementing the production casing within the surface casing, and removing the drilling adapter and blowout preventer after running the cement, but typically prior to cement bonding.
