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

NGN, by definition, is identified an infrastructure using packet technologies.– There is no specific mention which packet technology NGN should use,

but generally assuming IP as a dominant packet technology today.– 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’

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.– ITU-T SG 13 Q.7 has been developed 4 RECs on IPv6 based NGN

during the study period 2005~2008.

Relationship between NGN and IP

2. IPv6 based NGN

IPv6-based NGN: This is a NGN which support addressing, routing protocol and mechanisms of IPv6 IPv4-based NGN: This is a NGN which support addressing, routing protocol and mechanisms of IPv4 IPv6-based Non-NGN: This is an IPv6 based packet network which is not comply with NGN IPv4-based Non-NGN: This is an IPv4 based packet network which is not comply with NGN IPv4 based

2. IPv6 based NGN

Four Recommendations have been developed in SG13 Y.2051: General overview of IPv6-based NGN Y.2052: Framework of multi-homing in IPv6-based NGN Y.2053: Functional requirements for IPv6 migration in NGN Y.2054: Framework to support signalling for IPv6-based NGN

Recommendations on IPv6 based NGN

2. IPv6 based NGN

General requirements of IPv6–based NGN are identified requirements which influenced by IPv6 features

IPv6 based NGN shall share NGN R1 requirements generally Further requirements according to IPv6 features identified as IPv6

requirements IPv6 related requirements would be incorporated into NGN R2 requirements

• IPv6 based NGN shall accommodate the IPv6 addressing schemes. • IPv6-enabled FEs should differentiate the control information from the IPv6 packets. • IPv6-based NGN shall support the address transition and interworking without affecting the service provided to users. • IPv6-based NGN shall support the IPv6 extension headers and options.

General Requirements of IPv6 based NGN

Requirements of IPv6 based NGN (Y.2051)

2. IPv6 based NGN

ITU-T SG13 has been developed framework recommendations of IPv6 based NGN.

The concept and requirements of IPv6 based NGN will open one of the important gateway to use IPv6 technology/systems under the umbrella of NGN.

According to the shortage of IPv4 based address which also impact to the NGN deployment, IPv6 should be used more widely.

In addition, ‘Ubiquitous Networking’ will require more addresses and flexible but device/object targeted management which would be benefited from IPv6 features .

ITU-T SG13 Plans for IPv6 based NGN

2. IPv6 based NGN

Vision– Everything of value is connected to the network

• Physical mobility & Service mobility

Goals– Widespread interconnection of computing and

communication devices– Pervasive networks that include both wireline and wireless

segments– Mobile-to-fixed; mobile-to-mobile architectures– Includes public and private information spaces– Embedded intelligence, anywhere and anytime

Recommendation ITU-T Y.2002 (10/2009)

Vision and Goals of NGUN3. Next Generation Ubiquitous Networking

Definition of Ubiquitous Networking (Y.2002)

“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.”

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.

3. Next Generation Ubiquitous Networking

Fundamental Characteristics of NGUN (Y.2002)

IP connectivity: will allow objects involved in NGUN to communicate with each other, in particular, IPv6 will play a key role in object-to-object communications

Personalization: will allow to meet the user’s needs and to improve the user’s service experience

Intelligence: enables network capabilities to provide user-centric and context-aware service

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.

Smart devices: enable detection of environmental status and sensory information can utilize networking functionalities to enable interconnection between very small devices.
