X INTELLIGENT COMMUNICATION SYSTEMS

telecommunication description methods that are easy to use, and human-friendly
telecommunication environments.
The intelligent communication system is a direct result of more than 10 years
of industry experience, research activity, and education. In this book, the funda-
mentals of the foregoing research areas are described. For the research on telecom-
munication description methods, a description method based on state space is
described. For the research on human-friendly interfaces for telecommunication
services, AI applications that employ production systems, semantic networks, and
predicate logic are described. For the research on human-friendly telecommunica-
tion environments, the concepts of Telesensation and HyperReality are described.
Fundamental technologies such as computer vision are also discussed. Before
launching into these research areas, the book first covers telecommunication fun-
damentals, telecommunication network structures, advances in telecommunication
systems, information superhighways, and newly developed telecommunication
systems.
In Chapter 1, IT, which is the convergence of information processing and
telecommunication, is described. By combining information processing technol-
ogy with telecommunications, more human-friendly communication interfaces are
provided. Information technology provides not only telecommunication functions
but also more human-friendly human-machine environments. Where we describe
one of the IT architecture models, intelligent network (IN) architecture, the com-
ponents needed for IN architecture are defined.
In Chapter 2, communication fundamentals, such as connection methods, the
numbering plan, and protocols, are described. There are two connection methods:
the connection type of communication and the connectionless type of communi-
cation. Communication by telephone is a connection type of communication.
Communication by packet-switched network is a connectionless type of commu-
nication. In this chapter, the numbering plan of telephone service is described. By
standardizing the numbering plan around the globe, someone in one country can
telephone somebody in any other country.
In Chapter 3, communication network architecture is described. Initially, the
telephone network was constructed. Then the computer network was built based
on the telephone network according to advances in information processing tech-
nology. Recently, the Internet has been expanding throughout the globe. This chapter
describes the network architecture of the telephone network, the network architecture
of the computer network and the details of OSI protocol, and the network archi-
tecture of the Internet and the details of TCP/IP protocol.
In Chapter 4, the progress of telecommunication systems is described. Tele-
communication networks have advanced greatly, from an analog network to a dig-
ital network. Initially the service-dependent networks were constructed for a data
communication service and for a facsimile communication service. By integrating
all of these networks via the digital network, the integrated services digital network
(ISDN) was built.
