  • Patent number: 6937863
    Abstract: The invention discloses a system and method which quantifies the traffic or load on a particular sector of a mobile communication cell site. The traffic quantification or load metric is preferably used to compare the load of each of the cell site's sectors. When the difference between load among the sectors reaches a certain level, the preferred embodiment of the present invention causes the sectorization of the site to change in order to alleviate or equalize the traffic load of the sectors. The system of the present invention continues to monitor the cell site for traffic conditions and for changes in the load responsive to the sectorization changes made in order to dynamically respond to the changing traffic conditions on the cell site.

  • Patent number: 6829491
    Abstract: A communication network is dynamically optimized using network operation metrics, such as may be acquired from a network controller such as a mobile switching center, to achieve network performance goals. Operational parameter adjustments, associated with a particular network resource and corresponding network resources, are preferably determined as a function of the network operation metrics. Implementation of the parameter adjustments are modeled to determine if further or different operational parameter adjustments should be determined. Preferably, actual implementation of the parameter adjustments is effected in part through providing the adjusted parameters to the network controller. Additionally or alternatively, the adjusted parameters may be provided directly to one or more network resources for implementation.
