    Abstract: A method and system for optimizing system capacity and allocation in a CDMA cellular communication system obtains a current call volume and associated call characteristics for each of a plurality of cell sites in the system, and estimates effective boundaries for each of the plurality of cell sites to minimize the weighted sum of powers received at selected base stations. Selection of base stations can include highly loaded sites and adjoining cell sites. System parameters are then controlled to effect the estimated cell site boundaries. Thus, the present invention allows for dynamic shrinking and enlarging of cell boundaries to enhance the system capacity advantages of CDMA while maintaining contiguous coverage and avoiding coverage holes.

    Abstract: A SONET planning tool is provided for generating optimized SONET rings based on an existing SONET system capacity and anticipated system demand at minimal cost. The planning tool includes an analytical process that accurately models and utilizes embedded systems, linear chains, unidirectional rings, and bi-directional rings based on existing capabilities. In addition, large forecasted demands can be preprocessed with dedicated two-node rings, and multi-period studies can be generated.
