GSC9/Adm-005R1 Ubiquitous network- next generation service platform Masayoshi Ohashi KDDI Corporation GSC-9, Seoul
Overview • The next generation network • Concept of ubiquitous network • Role of ubiquitous network and its enablers • Conclusion GSC-9, Seoul
Users’ expectation toward the next generation • Users’ expectation toward the next generation service is not just to provide a large bandwidth. • They would rather expect to maintain or enhance their overall living environment, such as safety, security, amenity and feeling ease with the surrounding environment or within their community . • They are not aware which communication method they use . GSC-9, Seoul
Concept of ubiquitous network • A term “ubiquitous computing” is proposed by M. Wiser in early ’90s to express future distributed computing environment to support a user. This concept is also known as “pervasive computing” or “invisible computing.” • We call the background network supporting the ubiquitous computing as “ubiquitous network.” • Under the ubiquitous network, users can enjoy network services whenever and wherever they want (home, office, outdoors, etc).

Background and assumptions • Third generation cellular system is becoming dominant and person-to-person call is mostly made by cellular. • Fixed broadband services will come into home environment widely. Users will enjoy broadband access both at office and home. • Not only person-to-person communications, but other communications style such as machine-to-machine communications are gradually becoming popular.

The role of ubiquitous network • The role of ubiquitous network should seek for fulfilling such user needs in corporation with use terminal and service platform. • Keyword is “context awareness” for a user. • Context means user’s general situation such as user’s location, user’s access status, etc. • By always keeping aware of user’s context, a system can offer the best service that he/she wants.

Enablers The following items are several possible enablers for ubiquitous networking paradigm; • Advent of high-end mobiles which support 3G capability, location, middleware environment, sensors, etc. • RFID technology with which man-to-environment interactions much easier. • Ontology which deals with objects on the Web more semantic way than ever.

Flexible service platform is the key • From the ubiquitous service point of view, an ubiquitous network should have; • Flexible service platform execution environment with common API, • Super high performance switching and routing capability, • Broadband service capability, • QoS and relevant adaptive routing mechanism. GSC-9, Seoul
Role of NGN for ubiquitous paradigm • NGN should cover the fixed and FMC area to cover the next generation networks. • NGN should be flexible enough to support common service platform for global distributed service provisioning and control mechanism. • NGN should cooperate with other networks such as cellular networks, adhoc networks or sensor networks to be a key player for ubiquitous network. GSC-9, Seoul
Conclusion • Ubiquitous network is a federation of networks on which user oriented services are provided anywhere and anytime to a target user in the most appropriate way. This service provision paradigm is a strong driving force to the next generation network. • NGN has an important edge towards the realization of ubiquitous network in the fixed and FMC network area. • Common service execution platform on NGN is necessary to enable distributed service environment over full range of ubiquitous network. • NGN should go to UBIQUITOUS NETWORK.
