Users’ expectation toward the next Users’ expectation toward the next generation 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 .

Concept of ubiquitous networkConcept 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 assumptionsBackground 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 networkThe 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. GPS

Enablers 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 keyFlexible 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.

Role of NGN for ubiquitous paradigmRole 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 12

ConclusionConclusion• 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.
