The distribution server sends an information provision request with the information provision content added to the base station, and the location information server sends the information provision request with the information provision content to the GPS function of the information provider whose location information and telephone number match. Distributes information provision requests to mobile phones with GPS, gives location information to mobile phones with GPS function, distributes requested information provision contents to service providers, and service providers send from information providers Providing the requested information to the requesting organization has been proposed.

Patent Document 3 discloses a personal information providing system in which an owner of a mobile terminal device can automatically obtain personal information such as personal attributes and hobbies and information suitable for the current position. A mobile terminal device having a storage unit that can read the personal information from the outside via a wireless communication network, an information database for storing information according to the content of the personal information, and the storage via the wireless communication network The owner selects the mobile terminal device by selecting the information according to the content of the personal information acquired from the database from the database and providing the mobile terminal device with the server via the wireless communication network. There has been proposed an apparatus that can automatically obtain information that matches an individual attribute without the need for operation.
