COMMUNICATION PERFORMANCE CALCULATION METHOD AND COMMUNICATION PERFORMANCE CALCULATION APPARATUS IN MOBILE COMMUNICATION SYSTEM, AND BLOCKING PROBABILITY CALCULATION METHOD AND BLOCKING PROBABILITY CALCULATION APPARATUS IN COMMUNICATION SYSTEM, AND RECORDING MEDIUM

摘要

A method etc. for calculating traffic distribution at base stations and accurately and simply calculating the performance in the base stations in a mobile communication system is provided. A method etc. for simply and accurately calculating the blocking probability in a communication system is also provided. A subdivision data holding unit (602) holds data of transmission power Pi and traffic intensity Ai of each subdivision. A propagation associated data holding unit (604) holds data used for calculating received power, such as the height above the ground of antennas of the base stations and mobile stations. A received power calculating unit (606) reads necessary data from the subdivision data holding unit (602) and propagation associated data holding unit (604), and calculates the received power. A traffic calculating unit (608) calculates the means Sm and variances Sv of the traffic at the base stations from the data calculated by the received power calculating unit (606). A performance calculating unit (610) calculates the performance such as the blocking probability from the means Sm and variances Sv calculated by the traffic calculating unit (608) and from the threshold value T provided by the threshold value generator (612), and outputs the results.
