WIRELESS ENVIRONMENT DATABASE GENERATION DEVICE, MOBILE COMMUNICATION SYSTEM, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To appropriately determine a section size to generate an efficient wireless environment database when sectionalizing an observation target area and making a database of wireless environment data for each of a plurality of wireless access network systems included in a mobile communication system.;SOLUTION: A wireless environment database generation device comprises: a data collection unit 15 collecting wireless environment data whose data collection location and data collection time in an observation target area are identified, for each RAN; a wireless environment DB unit 13 storing the wireless environment data, for each RAN and for each section of the observation target area; a wireless environment change index calculation unit 21 calculating a wireless environment change index by using the wireless environment data, for each RAN and for each section of the observation target area; and a section update unit 22 updating a section size on the basis of the wireless environment change index and sectionalizing the observation target area again, for each RAN.;COPYRIGHT: (C)2015,JPO&INPIT
