Notifying the domain name server of three sets of the ICS domain name 1, the ICS user address 1, and the ICS network address 1, the domain name server holds these three sets internally,
The conversion table server is instructed to set the record 1 including the ICS user address 1 and the ICS user address of the registration server in the conversion table in the access control apparatus 1, and the conversion table server sets the record 1. The user 1 includes at least the ICS user address 1 and the ICS domain name 1, encryption related data 1, the encryption function, the roaming terminal common ICS user address, and the ICS user address of the registration server in the home terminal 1. Set,
The user 1 decides the password 1 used by the user 1, the source address is the ICS user address 1 of the user 1, the destination address is the ICS user address of the registration server, and at least the ICS domain name 1, encryption information 1 An ICS user frame including the following information is transmitted from the home terminal 1, and the encryption information 1 is generated using the encryption related data 1 and the password 1;
In the access control apparatus 1, the record 1 is used to form an ICS network frame X including the ICS user frame, the ICS network frame X reaches the registration server, and the registration server is directed to the authentication server. Forming and transmitting an ICS network frame Y including information of the ICS network frame X;
The authentication server restores the password 1 from the received ICS network frame Y, holds the set of the ICS domain name 1 and the password 1 therein, and performs roaming preparation by the above procedure. Integrated information communication system.

The IP transfer network includes a plurality of access control devices, a conversion table server, an authentication server, and a domain name server, and the access control device and the plurality of servers are connected by an internal communication line,
The access control device includes a conversion table composed of a plurality of records,
A plurality of terminals are connected to one of the access control devices via a user communication line, a logical terminal of a user communication line termination,
Terminal A and terminal B can communicate by transmitting and receiving an ICS user frame via terminal A-communication line A-access control apparatus A-inside the IP transfer network-access control apparatus B-communication line B-terminal B. Yes,
At least the access control device 2 has set a record R including the ICS user address of the roaming terminal common ICS and the ICS user address of the connection server in an internal conversion table,
The user 1 has at least a terminal 2 including an ICS user address 1 of the user 1, an ICS domain name 1 of the user 1, an encryption related data 1, an encryption function, an ICS user address common to roaming terminals, and an ICS user address of a connection server. 2 to
In order to establish communication connection from the terminal 2 to the terminal 3 having the ICS domain name 3, the source address is the ICS user address 1, the destination address is the ICS user address of the connection server, and at least the ICS domain name 1 and the ICS domain An ICS user frame 3 including an encryption parameter generated using the name 3, and the encryption-related data 1 and the password 1, and transmitted from the terminal 2 to the access control device 2,
The record R is used in the access control device 2 to form an ICS network frame 3X, the ICS network frame 3X reaches the connection server, the connection server receives the ICS network frame 3X, and the authentication server And confirms that the set of the domain name 1 of the user 1 and the password 1 of the user 1 included in the ICS user frame 3X is registered in the authentication server. Obtains an ICS user address and an ICS network address corresponding to the domain name 1 and the domain name 3 from the domain name server, and the connection server obtains addresses corresponding to the domain name 1 and the domain name 3. The access control device 2 including the record 2 including Instructs the conversion table server to set the conversion table, the connection server sends back an ICS user address 3 of at least the terminal 3 corresponding to the domain name 3 that the acquired to the terminal 2,
When the terminal 2 generates and transmits the ICS user frame 3 having the source address as the ICS user address 1 of the user 1 and the destination address as the ICS user address 3, the access control device 2 uses the ICS user frame. 3 becomes an ICS network frame 3 and is transferred through the IP transfer network, reaches the access control device 4 on the incoming side, and the ICS user frame 3 is restored to reach the terminal 3.
