Home Networking activities in TTC DOCUMENT #: GSC13-GTSC6-16r1 FOR: Presentation SOURCE: TTC AGENDA ITEM: 4.3: Home Network CONTACT(S): Kenji Koro (TTC: Next-Generation Home Network system WG Sub Leader) Home Networking activities in TTC 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. TTC Next-Generation Home Network system WG Submission Date: July 4, 2008

Highlight of Current Activities (1) -General- Propose the standardization about Home Networking (HN) in Japan Examination 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. Examination of a physical interface: Examination 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: Examination of Technical Demands Interconnection WG: Examination of Test bed

Highlight of Current Activities (2) Examination 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 Examination upon demand conditions by the Forum side, and TTC examines a concrete plan proposal based on it. Examination of the model for apparatus management Examination of a use case (Model of Profiles) Ｎ-Point A-Point Access Network Ｂ-Point IP Equipment WAN ＩＰ Home ＮＷ (Wired/Wireless) ＮＴ Access GW Non-ＩＰ Home ＮＷ (Wired/Wireless) Non-IP Adapter Non-IP Equipment Support Center, Service Provider WAN-Home Intra-Home 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

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

Challenges Examination of a device list The definition of QoS Examination 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.

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.) Examination of a profiles Define the details of each profiles Specification of an interface Examination 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
