OVERVIEW:
The environment surrounding the telecom industry is
undergoing great changes. Two key examples are the explosive growth of
the Internet and suspension or abolishment of various laws and regulations.
As a result of these changes, competition between telecom service providers
is becoming severe, and the satisfaction of customer needs by quick provision
of high-quality and inexpensive services has become a major issue. Here,
the development of telecom management systems based on a
Telecommunication Management Network (TMN) has taken on particular
importance as a means of dealing with this issue. In light of the above,
Hitachi is developing an integrated telecom management system featuring
not only network/service management systems but also customer-care/
business support systems, marketing/management support systems, and
customer-management/billing systems. This system will run on an open
distributed processing platform making use of Hitachi's extensive technical
expertise accumulated over many years of developing information-
processing systems. Hitachi hopes to make a significant contribution to the
telecom industry through this telecom management system.
INTRODUCTION
DUE to the explosive growth of the Internet, the public
communications network is making a transition from
a voice-oriented communications network centered
about the telephone to an information-oriented network
centered about multimedia information consisting of
data, images, etc. Advances in optical communication
technology and satellite communication technology
are also making it possible for high-speed and large-
capacity multimedia communications to be performed
regardless of time and location.
TECHNOLOGY TRENDS IN TELECOM
MANAGEMENT
Standardization of a telecommunication
management network (TMN) at ITU-T proceeds as a
technology for achieving telecom management
systems. The TMN is now being actively studied with
focus on equipment management, network
management, service management, and business
management. The TeleManagement Forum (TMF) in
particular is studying ways of achieving telecom
management systems based on TMN for info-
communication service providers, and they have
recommended a Telecom Operation Map (TOM) and
a Technology Integration Map (TIM) in this regard.
The TOM shows specific operation functions at each
management level and the information flow between
these functions. The TIM, on the other hand, presents
guidelines on how to go about achieving TOM.
CONCLUSIONS
Telecom management systems support many tasks
performed by telecom service providers. They can
improve work efficiency and help achieve quick
provision of low-cost services to customers.
Considering that telecom management systems are in
effect large-scale distributed information-processing
systems, Hitachi aims to make a significant
contribution to their development based on many years
of developing information systems and extensive
technical know-how.
