SYSTEM AND METHOD FOR CONSTRUCTING A CARRIER TO INTERFERENCE MATRIX BASED ON SUBSCRIBER CALLS
First Claim
1. A method, comprising:
- receiving, by a system comprising a processor, signals from wireless antennas on a common frequency of a control channel associated with a station pair,wherein the wireless antennas comprise base station devices that provide service to different network sectors, and information associated with the signals is stored in a data structure having a number of entries that corresponds to a number of occurrences of an interference parameter within a selected range for the station pair;
determining, by the system, a number of carrier-to-interference occurrences for the station pair;
determining, by the system, a relative percentage for the number of occurrences of the interference parameter;
measuring, by the system, during the measurement period, relative signal strengths with respect to control channel signals transmitted by the wireless antennas; and
determining, by the system, traffic weights for a subset of the number of occurrences of the interference parameter within the measurement period.

Abstract
A conventional wireless device constantly measures the signal strength of its server base station and the strength of signals from surrounding base stations for handoff purposes. The wireless device transmits this information to its serving base station, which discards the information a short time afterward, following handoff. The present system and method store the formerly discarded information in one of several existing network elements or in a separate computer system. This information is used to generate a carrier to interference ratio, which indicates the level of interference between station pairs, and to also generate a carrier to interference matrix, including identifying potential interference for each station pair. The frequency of occurrences during predetermined desired periods of time and the volume of traffic affected by each level of interference may also be calculated. This provides comprehensive, continuous, real-time information for wireless frequency planning.
