Abstract
An improved wireless information processing apparatus that is connectable to an appropriate one of the access points prepared by an internet provider even under a mobile environment. A terminal and method of operation whereby a user of the terminal requests connection to the Internet, the terminal extracts a CS-ID from notification information transmitted from a wireless base station and, then, retrieves its own association table to acquire a telephone number of an access point nearest to the current location. Then, the terminal dials-up to the acquired access point to establish an internet connection. As a result, the terminal is allowed to download an electronic mail destined therefor, a Web page (HTML file or the like) stored in a disk of a given Web server and the like. Alternatively, the terminal is allowed to transmit data contained therein (or a file and/or an electronic mail edited on this terminal) to another computer system connected to the Internet, or to upload such data to a disk of a given Web server.
