Question 24/13 – Service scenarios, deployment models and migration issues
(Merger of Qs 13/13 and 14/13)

Motivation
As NGN and Future Networks scope covers wide areas of network, it needs to make simple and clear business deployment models for definition of NGN and Future Networks. Then, a set of promising service scenarios and deployment models of NGN and Future Networks are very useful to accelerate the NGN and Future Networks deployment. All the scenarios should be initiated from the user point of views, which would be described as use cases.

Service scenarios could be designed to enable operators to support key networking environments and build differentiated advantages through business innovation.

At the same time, operators of existing telecommunication networks have expressed concerns connected with the necessity of full replacement of their network equipment when migrating from traditional telecommunication networks to NGN and Future Networks. The requirement to protect their investments in the existing network infrastructure causes operators to seek possible solutions for gradual transition from their existing telecommunication networks to NGN and Future Networks with step-by-step replacement of equipment.

For Future Networks, more and more new technologies will be introduced, e.g. Cloud Computing, IoT, etc. The architecture and deployment of Future Networks will be probably largely different from the existing telecommunication networks. Foregoing requirements will be still available when existing telecommunication networks or NGN migrate to Future Networks.

Question
Study items to be considered include, but are not limited to:
  • From user point of view, application specific NGN and Future Networks service scenarios including application services and end-user functions. It is pointed out that new application services in NGN and Future Networks stemming from convergence service environments should also be studied.
  • Technology-based NGN and Future Networks service scenarios by considering computer technology, security technology, electronic appliance technology, broadcast technology including interactive wireless/mobile technology, and telecommunication technology including enterprise and various access technologies.
  • step-by-step migration scenarios to NGN and Future Networks
  • Approaches in these scenarios will contribute to energy savings directly or indirectly in Information and Communication Technologies (ICTs) or in other industries
Tasks
Tasks include, but are not limited to:
  • Develop documents on NGN and Future Networks service scenarios including emerging services and converged services.
  • Develop documents on NGN and Future Networks based IPTV service scenarios that converge traditional broadcasting services and telecommunication services over the NGN and Future Networks environment.
  • Develop documents on service scenarios of use cases and 3rd party services for ubiquitous environments.
  • Develop documents on migration scenarios to NGN and Future Networks.
  • Develop documents on decision factors for selecting migration scenarios and migration criteria through analysis of the scenarios.
  • Continue documents currently under way.
  • Documents produced under this Question will normally be published as Supplements or will progress through, or in coordination with, other related Questions.
Relationships
Close cooperation with other ITU-T study groups (for services and applications) and other organizations must take place.
