  • Publication number: 20130242736
    Abstract: In some embodiments, an apparatus includes a management module implemented in at least one of a memory or a processing device. The management module is configured to receive a signal associated with a value of a performance indicator that a first process module is configured to optimize using a metric. The management module is configured to optimize a value associated with the metric based at least in part on the value of the performance indicator that the first process module is configured to optimize and a value of a performance indicator that a second process module is configured to optimize using the metric. The management module is configured to send a signal to the first process module such that the first process module modifies a value of the metric based on the value associated with the metric.

  • Patent number: 8509762
    Abstract: In some embodiments, an apparatus includes a monitor module, a detector module and an adjustment module. The monitor module is configured to receive a set of indicators from a wireless network. The detector module is configured to detect an underperformance condition during a time period and within a first cell of the wireless network based on the set of indicators. The adjustment module is configured to iteratively adjust a parameter associated with a second cell of the wireless network to produce an adjusted parameter. The adjustment module is configured to send the adjusted parameter to the wireless network to improve performance of the wireless network. The adjustment module is configured to restore, after the time period, the parameter associated with the second cell to a value equal to a value for the parameter prior to the time period, and send that value of the parameter to the wireless network.

  • Patent number: 8489031
    Abstract: An apparatus, system, method and program detect and reduce interference in cell sites of a wireless communications network. A cell site from the cell sites of the wireless communications network is selected and signal code power measurements from mobile devices in the cell site are received so that the sources of signals being transmitted to the mobile devices can be determined. Interfering sources are determined based on the signal code power measurements and the active set of sources for the mobile devices. The signal code power measurements are summed and ranked, and interfering transmitters associated with the ranked signal code power measurements for the interfering sources are determined. The same procedure is repeated for all cell sites of the wireless communications network, and the transmitter that is an interfering source for the highest number of cell sites is selected as a problem (interfering) transmitter.

  • Publication number: 20120295605
    Abstract: An apparatus, method and program reduce interference in interfered cell sites of a wireless communications network. A cell site is a region in which wireless communications are provided to mobile devices, and the interfered cell sites being cell sites where mobile devices are subject to interference signals from at least one interfering transmitter. A transmitter is selected from a list of interfering transmitters in need of adjustment and corresponding antennas. A critical zone is determined with respect to the selected transmitter. Parameters of the selected transmitter and the corresponding antenna are altered and performance of the wireless network in the critical zone around the problem transmitter and interference in the cell sites interfered by the problem transmitter are monitored. Altering of the parameters of the transmitter and the corresponding antenna is performed continuously until a desired interference reduction is achieved in the cell sites interfered by the selected transmitter.
