Patent ID: 7945435

Claim:
A search system for searching, within a spatially expanded evaluation-target area, a radio non-sensitive area where a radio wave of an already-provided radio communication system cannot reach sufficiently, the search system using as data used for the search, radio environment data, digital map data, and use condition data, wherein: the radio environment data is current radio environment data of the radio communication system in the evaluation-target area, and each of the radio environment data is individually correlated to search targets within the evaluation-target area; the digital map data is digital map data including the evaluation-target area, which contains individual area attribute information for the search targets; and the use condition data is use condition data of the radio communication system or a radio communication system similar to the radio communication system, and each of the use condition data is individually correlated to already-provided service areas as well as to parameters of attribute information of the search targets, the search system comprising: a non-sensitive area extracting device which extracts the search targets and obtains the attribute information of the search targets by correlating the radio environment data to the attribute information of the search targets; an effect quantization equation creating device which creates, using a processor, a calculating equation for quantizing an effect that a communication company obtains by making an area where the search targets exist into its service area, by having the parameters of the attribute information of the search targets as direct or indirect explanatory variables through correlating the use condition data to the attribute information of the search targets; and an effect quantizing device which calculates the effect that the communication company obtains by making the area where the search targets exist into its service area through applying the calculating equation to the extracted search targets, and applies an priority order for taking a search-target countermeasure on a plurality of the search targets extracted within the evaluation-target area based on the effects calculated individually.
