The Role of Network Service System Development
ABSTRACT
Recently, network services have been evolving at a startling pace. I heard a quiz question that asked, ‘The most important
single item to keep with you when traveling abroad is your passport. What is the most important item to carry when you are
traveling in Japan?’ The answer was a mobile phone. This is because we constantly use mobile phones for a wide range of
familiar applications; they serve as telephone set, e-mail terminal, clock, scheduler, address book, camera, voice recorder, and
video recorder. We can even use them to reserve tickets or check train routes and schedules. In the future, we can expect that
mobile phones will be used for even more diverse applications, such as electronic wallets and electronic passports. In addition
to mobile phones, new devices are appearing one after another, such as information appliances, wearable computers, and IC
tags, and services are becoming increasingly diverse. Some of these services can be received using only the devices themselves
in a stand-alone manner, but in many cases network connections are essential or raise the value of these services dramatically.
Supporting this networking is at the core of the NTT Group’s business.
