  • Publication number: 20200359284
    Abstract: A device can receive, from a network node device, call trace event data relating to characteristics of a wireless communication session between the network node device and a user equipment. The device can sequence and combine the call trace event data for a period of the wireless communication session. The device can analyze the call trace event data to determine a category of network communication traffic transmitted via a communication channel between the network node device and the user equipment. In response to a determination that the network communication traffic comprises streaming video packets, the device can facilitate directing of network resources to be allocated to support the wireless communication session.

  • Patent number: 10819585
    Abstract: A network device that determines RACH root sequences for AP devices within a given market. The network device can utilize a specialized graph coloring process or algorithm that has been adapted to, e.g., ensure that no two neighboring AP devices share the same RACH root sequences, provided certain additional constraints not found in graph coloring theory are met. For example, AP devices can have multiple RACH root sequence, whereas in traditional graph coloring problems, each vertex typically has only one color.

  • Patent number: 10681561
    Abstract: A method and apparatus for providing planning of a plurality of base station controllers in a wireless network are disclosed. For example, the method obtains input data, and determines a limit for at least one base station controller parameter in accordance with the input data. The method determines if the limit for the at least one base station controller parameter is exceeded and determines an optimal output for an objective function, wherein the objective function is based on a plurality of penalty factors, if the limit for the at least one base station controller parameter is exceeded.

  • Publication number: 20190311270
    Abstract: Concepts and technologies disclosed herein are directed to the optimization of over-the-air (“OTA”) file distribution for connected cars based upon a heuristic scheduling algorithm. A schedule provided by the heuristic scheduling algorithm is designed to distribute OTA data flow to connected cars over the network (geographically) and over a scheduling time horizon (timely), and is capable of reducing the negative impact of OTA file updates on overall wireless network performance. This schedule is created based upon historical statistics associated with connected car driving patterns and simulations of connected car-specific OTA traffic over the network. By leveraging connected cars that connect to different cells at different times based upon driving patterns, the heuristic scheduling algorithm is effective in reducing OTA impact on the network.

  • Patent number: 10375668
    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: 9848337
    Abstract: Dynamic metro cell location planning is provided within the wireless communication coverage area of a macro cell. Metro cell location planning can include obtaining performance parameters associated with the macro cell and evaluating coverage parameters of the macro cell. Metro cell location planning can also include selecting, based on the performance parameters and the coverage parameters, a location within a wireless communication coverage area of the macro cell for placement of the metro cell. The selected location can be conveyed to a user and/or entity for deployment of the metro cells. Metro cells can be used by a carrier to fill a coverage hole and/or to offload capacity hot-spots within the network.
