Overview

• The next generation network
• Concept of ubiquitous network
• Role of ubiquitous network and its enablers
• Conclusion

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 .

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 users general situation such as
  users location, users access status, etc.
• By always keeping aware of users 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.

11
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.

12
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.
