Abstract
The present invention provides a portable information system the enables a user to access necessary information from a home page of a store even when the user does not know the URL of the home page. In order to attain this, a portable information terminal 1 has a wireless telephone communication function, such as a PHS, and a guide switch 1c that requests area information from the Internet provider 5, transmits via an antenna 1A to base station 3A or base station 3B, and obtains information about the current position by GPS. In addition, the base station 3A and base station 3B are connected to the ISDN public telecommunication network 2, for example, via an exchange, and connect the communication line between the public telecommunication network 2 and the portable information terminal 1. In addition, a server 5c having a database 5d that stores data is connected to the telecommunication network 2 via the access points 4A-4D of the Internet provider 5 and the provider communication network 5a. In the above structure, the portable information terminal 1 accesses the server 5c uses current position information and guide control signals, searches for information about stores in the area that indicated by the current position information, and transmits this information to the portable information terminal 1.
