Integrated information communication system

Abstract

A communication system, for functioning without the use of dedicated lines or the Internet so as to ensure communication speed, communication quality, and communication trouble countermeasures, including a communication network and domain name server. The domain name server includes a domain name tree with a country number of a telephone number as a level 2 domain name of the domain name tree, and the domain name server receives, from a terminal, a telephone number of a destination terminal. Furthermore, based on the telephone number of the destination terminal, the domain name server (i) seeks out, in the domain name tree, an Integrated Information Communication System (ICS) user address of the destination terminal, and (ii) sends the ICS user address to the terminal, such that the communication system receives, from the terminal, the ICS user address as a destination address, and sends the ICS user frame to the destination terminal.

1 . A communication system comprising a sending side Integrated Information Communication System (ICS) logical terminal and a receiving side ICS logical terminal, wherein:
 based on said sending side ICS logical terminal and an ICS user address of an ICS user frame inputted from said sending side ICS logical terminal, an ICS network address of an ICS network frame is settled; and   based on said ICS network address, said receiving side ICS logical terminal, which receives said ICS network frame, is settled.   
     
     
         2 . The communication system according to  claim 1 , wherein said communication system is connected to another communication network connected to a cellular phone and said communication system communicates with said cellular phone. 
     
     
         3 . A communication system comprising a sending side Integrated Information Communication System (ICS) logical terminal and a receiving side logical terminal,
 wherein, based on said sending side ICS logical terminal and an ICS user address of an ICS user frame inputted from said sending side ICS logical terminal, said receiving side logical terminal, which receives an ICS network frame including said ICS user frame, is settled.   
     
     
         4 . The communication system according to  claim 3 , wherein said ICS user frame includes a voice. 
     
     
         5 . A communication system comprising a sending side Integrated Information Communication System (ICS) logical terminal and a receiving side ICS logical terminal,
 wherein, based on an information to discriminate said sending side ICS logical terminal and an ICS user address of an ICS user frame inputted from said sending side ICS logical terminal, said receiving side ICS logical terminal is settled.   
     
     
         6 . The communication system according to  claim 5 , wherein said communication system is connected to a public telephone network connected to a terminal and said communication system communicates with said terminal. 
     
     
         7 . A terminal-to-terminal communication system comprising a sending side Integrated Information Communication System (ICS) logical terminal,
 wherein, based on an information to discriminate said sending side ICS logical terminal and an ICS user address of an ICS user frame inputted from said sending side ICS logical terminal, a communication line, in which an ICS network frame including said ICS user frame is transferred between a sending side access control apparatus and a receiving side addess control apparatus, is settled.   
     
     
         8 . A communication system comprising a sending side Integrated Information Communication System (ICS) logical terminal and a receiving side ICS logical terminal,
 wherein, based on an information to discriminate said sending side ICS logical terminal and an ICS user address of an ICS user frame inputted from said sending side ICS logical terminal, a communication line, in which an ICS network frame including said ICS user frame is transferred between said sending side ICS logical terminal and said receiving side ICS logical terminal, is settled.
