Heretofore, when establishing a radio network which uses a plurality of radio base stations, it is necessary to set parameters of the radio base stations according to the radio propagation environment of an actual environment. Examples of parameter contents of radio base stations include the antenna direction of the radio base stations and signal parameters of radio signals to be transmitted and/or received by the radio base stations (refer to Patent Document 1).
In order to determine these types of radio parameters, there have been performed operations such as data acquisition by running tests, and execution of radio propagation environment simulation processes based on acquired data.
