Therefore, the number of switching operations of the provider server in the terminal can be reduced.

It should be noted that in the present specification, the switching of the line connection with the provider server in downloading the electronic information from the provider server to the terminal has been described, but the terminal is not limited to downloading the electronic information. The invention described in this specification can also be used when switching the line connection with the provider server when transmitting the electronic information input / created / edited, etc. to the provider server and the Internet network.

[0083]

As described above, according to the present invention, a telephone line in which a request signal is received from a terminal when switching a line from a connected server to another one among a plurality of provider servers In the network, while maintaining the connection state with the terminal device, the line is disconnected and connected with the provider server, so that the communication cost can be reduced.

Further, in the telephone line network, since it is possible to automatically circulate through a plurality of provider servers by receiving one call connection to receive an electronic mail, the number of operations such as line connection in the terminal can be reduced. Further, since the connection state is maintained between the terminal and the telephone line network when switching the provider server, the time required for line connection and line disconnection conventionally made for each of a plurality of provider servers. Can be reduced. Therefore, it is possible to reduce the total time required for downloading a plurality of e-mails and the switching time for switching to another provider's server.

In the Internet information communication system, the called number, which is the connection condition of the provider server, is set in the extension part of the initial DP signal at the service exchange point, and the set connection condition is saved in the data at the service control point. Then, when the provider server is switched, the stored data is set to CONN, and thus the connection to the provider server can be performed without acquiring the connection condition with the provider server from the terminal. It is possible to switch, and the number of switching operations of the provider server in the terminal can be reduced.
