  • Method for topology analysis in the verification of neighbor and target lists in a CDMA network
    Patent number: 6545984
    Abstract: A method for analyzing the topology of a CDMA network with respect to both neighbor and target lists is disclosed. The method first defines a language that creates an input source file for communicating the layout of the CDMA network. The language expresses the sector-neighbor list relationships of all sectors in the CDMA network. Next, the method parses and builds a directed graph from the input source file to perform topology analysis of the CDMA network. The method then analyzes the input source file and directed graph for possible errors in the network layout that will lead to dropped calls. The method renders a report to the user about those error conditions and emits a file to be used as input into the CDMA database.
