In some embodiments, an apparatus includes a cluster partitioning module and an optimization module. The cluster partitioning module receives a first performance indicator set for a first instance of a time period set. The cluster partitioning module defines a recurring schedule set, where each time period from the recurring schedule set is associated with a performance indicator from the first performance indicator set and within a predefined range of a performance indicator associated with the remaining time periods from the recurring schedule set. The optimization module receives a second performance indicator set for a second instance of the time period set. The optimization module defines a metric value based on the second performance indicator set, and causes a change in a network implementation based on the metric value at each time period from a third instance of the time period set and from the recurring schedule set.

Methods and apparatus for partitioning wireless network cells into time-based clusters

Optimizing a plurality of cell sites or sectors in a wireless network including receiving network data regarding a plurality of cell sites or sectors; determining a critical zone in which communication is degraded; determining best neighbor cell sites or sectors among the neighbor cell sites or sectors associated with the critical cell sites or sectors; determining if the critical cell sites or sectors in the critical zone have available resources for achieving a desired improvement in communications; determining if the best neighbor cell sites or sectors have available resources for achieving the desired improvement in communications; and altering wireless network parameters of the critical cell sites or sectors, or the best neighbor cell sites or sectors for achieving the desired improvement in communications. Altering wireless network parameters of the critical cell sites or sectors, or the best neighbor cell sites or sectors is performed continuously until the desired improvement in communications in the wireless network is achieved.

Self-optimizing wireless network

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.

A non-transitory processor-readable medium stores code to cause a processor to receive a performance indicator associated with a first mode. The code causes the processor to calculate, using the performance indicator associated with the first mode, a first metric value associated with a first metric and an objective of the first mode. The code causes the processor to calculate, using the first metric value, a second metric value associated with a second metric and an objective of a second mode. The second metric value partially compensates for a change in a performance indicator associated with the second mode when the first metric value is implemented. The code causes the processor to send a signal associated with the first metric value and a signal associated with the second metric value to an antenna module such that the antenna module implements the first metric value and the second metric value.

Methods and apparatus for coordination in multi-mode networks

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.

Methods and apparatus for underperforming cell detection and recovery in a wireless network

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. The parameters of the problem transmitter and the corresponding antenna are altered and performance of the wireless network in a 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 problem transmitter and the corresponding antenna is performed continuously until a desired interference reduction is achieved in the cell sites interfered by the problem transmitter.
