  3. 3. Definition of NGN ITU-T Rec. Y.2001 Next Generation Network (NGN) : a packet-based network able to provide telecommunication services and able to make use of multiple broadband , QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies . It enables unfettered access for users to networks and to competing service providers and/or services of their choice. It supports generalized mobility which will allow consistent and ubiquitous provision of services to users. 1. One shot overview of NGN
  4. 4. <ul><li>NGN, by definition, is identified an infrastructure using packet technologies. </li></ul><ul><ul><li>There is no specific mention which packet technology NGN should use, but generally assuming IP as a dominant packet technology today. </li></ul></ul><ul><ul><li>There are also no specific statement to specify the version of IP such as ‘version 4’, ‘version 6’ or ‘version 9,’ but most parts of NGN related ITU-T RECs are mainly assumed ‘version 4’ </li></ul></ul><ul><li>ITU-T has been initiated the study on ‘Impacts of IPv6 into the NGN’ which looks for the usage of IPv6 features into the NGN. </li></ul><ul><ul><li>ITU-T SG 13 Q.7 has been developed 4 RECs on IPv6 based NGN during the study period 2005~2008. </li></ul></ul>Relationship between NGN and IP 2.

  13. 13. Definition of Ubiquitous Networking (Y.2002) <ul><li>“ The ability for persons and/or devices to access services and communicate while minimizing technical restrictions regarding where, when and how these services are accessed, in the context of the service(s) subscribed to.” </li></ul><ul><li>NOTE – Although technical restrictions to access services and communicate may be minimized, other constraints such as regulatory, national, provider and environmental constraints may impose further restrictions. </li></ul>3. Next Generation Ubiquitous Networking

  15. 15. Fundamental Characteristics of NGUN (Y.2002) <ul><li>IP connectivity : w ill allow objects involved in NGUN to communicate with each other, in particular, IPv6 will play a key role in object-to-object communications </li></ul><ul><li>Personalization : will allow to meet the user’s needs and to improve the user’s service experience </li></ul><ul><li>Intelligence : enables network capabilities to provide user-centric and context-aware service </li></ul><ul><li>Tagging objects : will allow to get and retrieve information of objects from anywhere through the network. As IP technology will be used for ubiquitous networking, it is essential to develop mapping solutions between tag-based objects (e.g. RFIDs) and IP addresses. </li></ul><ul><li>Smart devices : enable detection of environmental status and sensory information can utilize networking functionalities to enable interconnection between very small devices. </li></ul>3.
