TERMINAL DEVICE, SERVER DEVICE, CONNECTING DESTINATION SWITCHING METHOD, AND COMPUTER PROGRAM

PROBLEM TO BE SOLVED: To provide a terminal device facilitating switching of connection to another remote network by a user. SOLUTION: The terminal device 10a transmits, in response to an operation by the user, an information request to a server device 30s. The terminal device receives, as a response, a character string containing an URL to information which can be referred to by a private network 40a and a predetermined character string added thereto from the server device 30s. The terminal reads a telephone number of a RAS 21b contained in the predetermined character string, transmits a connection request to the RAS 21b, and receives a connection response. The terminal then transmits an authentication request containing ID information and password information of the user contained in the predetermined character string to the RAS 21b. The terminal receives an authentication response with an approval authentication result from the RAS 21b, receives information of an IP address for connecting with the private network 40a or the like from the RAS 21b, and registers it inside. Finally, the terminal transmits a connection request containing the URL to the private network 40a. COPYRIGHT: (C)2006,JPO&NCIPI
