Home Networking activities in TTC DOCUMENT #:GSC13-GTSC6-16 FOR:Presentation SOURCE:TTC AGENDA ITEM:4.3: Home Networking CONTACT(S):Kenji Koro Submission Date: July 14, 2008 TTC Next-Generation Home Network system WG Outline: To provide activity and future plan on Home Networking in TTC. To provide co-ordinate activity and future plan on Home Networking in JAPAN.

2 -General- Decision of the standardization about Home Networking (HN) –Decision of architecture: The revision proposal to ITU SG9 –Interconnection: Aim at the standard establishment about a required function and functional layout, such as a transmission system, QoS, and GW control function. –Decision of a physical interface: Decision of a model in Home Connector –Standardization proposal to ITU-T etc. : Under proposal progress Investigation and analysis of related Recommendations –ITU-T, HGI, DSL-Forum, DLNA, UPnP, etc. Cooperation with a related organization –Next Generation IP Network Promotion Forum in Japan: Home Network WG: Decides Technical Demands Interconnection WG: Examination of a test bed Highlight of Current Activities (1)

3 Highlight of Current Activities (2) Decision of the priority for standardization –QoS and Remote management are the first target. –Under examination about the details of QoS, and a device list now. Cooperation with Next Generation IP Network Promotion Forum –Decides upon demand conditions by the Forum side, and TTC examines a concrete plan proposal based on it. Examination and decision of the model for apparatus management Examination decision of a use case (Model of Profiles) Access Network Ｎ -Point Ｂ -Point IP Equipment Non-IP Equipment Non-IP Adapter A-Point Access GW ＩＰ Home ＮＷ (Wired/Wireless) ＮＴ - Setup - Home NW apparatus management - Failure / Quality Management (WAN / home NW) ・ Setup ・ Apparatus specification ・ The surveillance/notice of NW connection / quality ・ Apparatus state detection and a notice Support Center, Service Provider Non- ＩＰ Home ＮＷ (Wired/Wireless) WAN-Home Intra-Home WAN

4 Strategic Direction There are no synthetically Recommendation between WAN, Access, Home-GW, and Intra-HN NW. –QoS –Operation –Connection Their own specification in various kinds of organizations. Isn't cooperation by its side necessity among several bodies?

5 Challenges Decision of a device list –Decision of a model in HN The definition of QoS –QoS in HN –End to END QoS Cooperation with Next Generation IP Network Promotion Forum –Demand to QoS is considered. –Interconnection Experiments.

6 Next Steps/Actions Embodiment of use case: Internet connectivity, IP phone, Contents distribution (included IPTV), Life system support (an Emergency dialing, Home security, Energy management, etc.) –Decision of a profiles –Define the details of each profiles Specification of an interface –Decision of a specification proposal Cooperation with related many organizations: Demand to Operation, Managements, Interconnection tests –Cooperation with the Forum intra Japan –Cooperation with the Forum inter Japan
