Communicaton system, and connection setting method and connection setting program of exchange and terminal

An exchange connected to an outside communication network, for relaying a connection from a terminal to said communication network, which

• receives a connection setting request for connecting said terminal to said communication network, including terminal identification information for identifying said terminal uniquely, from said terminal, and
• searches for stored communication setting information of said terminal, according to said received terminal identification information of said terminal and performs the connection setting for connecting said terminal to said communication network, according to said communication setting information.

A terminal to be connected to an outside communication network, through an exchange for connecting said terminal to said communication network, said terminal which

• requests said exchange to perform a connection setting for connecting said terminal to said communication network, by sending transmission data including terminal identification information for uniquely identifying said terminal, to said exchange, where stored communication setting information of said terminal is searched for according to said received terminal identification information of said terminal and the connection setting is performed according to said communication setting information.

A method of setting a connection from a terminal to an outside communication network, in an exchange connected to said communication network, for relaying the connection, comprising the following steps of:

• said terminal sends terminal identification information for identifying said terminal uniquely to said exchange, so to request said exchange a setting for connection with said communication network;
• and
• upon receipt of the connection setting request, said exchange searches for stored communication setting information of said terminal, according to said received terminal identification information of said terminal and performs the connection setting for connecting said terminal to said communication network, according to said communication setting information.

A connection setting program for connecting a terminal to an outside communication network, by controlling a computer, comprising the following functions of:

• said terminal sends terminal identification information for identifying said terminal uniquely to said exchange, so to request said exchange a setting for connection with said communication network;
• and
• upon receipt of the connection setting request, said exchange searches for stored communication setting information of said terminal, according to said received terminal identification information of said terminal and performs the connection setting for connecting said terminal to said communication network, according to said communication setting information.

A server connected to an outside communication network, for setting a connection from a terminal to the communication network, the server which

• receives a connection setting request for connecting said terminal to said communication network, including terminal identification information for identifying said terminal uniquely, from said terminal;
• and
• searches for stored communication setting information of said terminal, according to said received terminal identification information of said terminal and performs the connection setting for connecting said terminal to said communication network, according to said communication setting information.
