  • Patent number: 9813977
    Abstract: WI-FI/3GPP access selection techniques are used to control selection by a user terminal between cellular network cells and WI-FI cells. Cellular network cells providing overlapping coverage with WI-FI cells are correlated with the WI-FI cells. A received signal strength threshold is determined for each WI-FI cell based on an average throughput of the cellular network cells correlated with the WI-FI cell. The WI-FI user terminal admit threshold is used to control the effective coverage of the WI-FI cell. A user terminal operating within a cellular network cell is admitted to a WI-FI only if it is within the effective coverage area of the WI-FI cell as determined by the received signal strength threshold. Increasing the threshold shrinks the effective coverage area of the WI-FI cell to allow user terminal only of strong RSSI to make connection to the cell, and steers user terminal of weak RSSI away from the WI-FI cell.

  • Patent number: 9625497
    Abstract: Prediction techniques are presented for predicting a current value of a performance measurement using historic performance measurement data and recent performance measurement data, which may not reflect the current conditions. A daily trend in a series of performance measurements is obtained. The daily trend comprises a set of data points at different times of day, wherein each data point represents an average value of the performance measurements at a corresponding time of day over a plurality of days. One or more recent performance measurements over a recent time interval are also obtained. A current value of the performance measurements is predicted, based on the daily trend and the recent performance measurements.

  • Patent number: 9572065
    Abstract: A method for equalizing an average throughput of a plurality of wireless communication network access points is provided. Each access point having a respective average throughput value and at least one control parameter, the at least one control parameter controlling wireless connectivity at the access point. An average throughput value received from each of the plurality of access points is determined. A first wireless communication network access point for configuration is determined based on the average throughput values received from each of the plurality of access points. The at least one control parameter of the determined first wireless communication network access point is set to at least one threshold value to effect equalization of the average throughput values among the wireless communication network access points.

    Abstract: WI-FI/3GPP access selection techniques are used to control selection by a user terminal between cellular network cells and WI-FI cells. Cellular network cells providing overlapping coverage with WI-FI cells are correlated with the WI-FI cells. A received signal strength threshold is determined for each WI-FI cell based on an average throughput of the cellular network cells correlated with the WI-FI cell. The WI-FI user terminal admit threshold is used to control the effective coverage of the WI-FI cell. A user terminal operating within a cellular network cell is admitted to a WI-FI only if it is within the effective coverage area of the WI-FI cell as determined by the received signal strength threshold. Increasing the threshold shrinks the effective coverage area of the WI-FI cell to allow user terminal only of strong RSSI to make connection to the cell, and steers user terminal of weak RSSI away from the WI-FI cell.
