Question 12/13 – Evolution towards integrated multi-service networks and interworking
(Continuation of Question 7/13 and Question 12/13)

Motivation

The rapid growth and the embedded base of legacy telecommunications networks have necessitated a strategy of evolution towards integrated multi-service networks which connect to enterprise and home networks. Due to popularity of the IPTV and transformation of networks to NGN it has become necessary to include study of home networks. Thus the focus of this Question will include activities related to IP television (IPTV) and home networks. This Question will address items such as:

  • determination of how best to carry narrow-band and broadband services of a fully integrated IP-based network across non-IP based networks (e.g. FR and ATM);
  • description of interworking of services, including definition of protocol requirements;
  • interworking of services between home network operator administered networks.

Recommendations under responsibility of this Question include:

I.500 series, Q.933, Q.933bis, X.36, X.76, X.84, X.142, X.144, X.145, X.146, X.147, X.148, X.149, X.151, X.272, Y.1400 series, Y.2261, Y.2262 and Y.2271

Question

Study items to be considered include, but are not limited to:

  • What enhancements to the existing Recommendations should be made to enable interworking between the legacy networks and the NGN?
  • What new Recommendations should be developed for home networks, including their ability to support IPTV?
  • What new Recommendations should be developed to facilitate greater interoperability between different networks?
  • What enhancements to existing Recommendations are required to provide energy savings directly or indirectly in information and communication technologies (ICTs) or in other industries? What enhancements to developing or new Recommendations are required to provide such energy savings?

Tasks

Tasks include but are not limited to:

  • Creation of, maintenance and enhancement to the Recommendations in Y.1400 series
  • Maintenance of Recommendations Y.2261, Y.2262 and Y.2271
  • Maintenance and enhancement to the Recommendations in I.500 series
  • Maintenance and enhancement to Recommendations Q.933, Q.933bis, X.36, X.76, X.84, X.142, X.144, X.145, X.146, X.147, X.148, X.149, X.151 and X.272 and the development of new Recommendations as deemed necessary
  • Completion of draft Recommendations already under discussion in Questions 12/13
  • Development of new Recommendations related to home network and their interworking aspects with the operator administered networks
  • Development of new Recommendations related to interworking to support IPTV services

Relationships

Recommendations: I-, Q-, X- and Y-series

Questions: All NGN, IPTV and home network related Questions
