Abstract

In a service providing system, a first database holds plural kinds of balloon data, in which each of plural pieces of three-dimensional real space range information and an identifier for identifying the three-dimensional real space range information is related, and a second database holds a service execution file in which each of plural pieces of three-dimensional space region information related to each identifier and service information in each three-dimensional space region are related. An extracting unit extracts, using position on a user terminal and an identifier, a service execution file corresponding to a three-dimensional space region. A service execution processing unit performs an executing process of a service corresponding to service information held in the extracted service execution file. The service system provides various kinds of services information at any time, effectively use the hardware, and limit the access. The user obtains service information available in a wide area.
