Document No: GSC17-PLEN-32 Source: TTC Contact: Kenji KORO GSC Session: PLEN Agenda Item: 6.14 Home Networking activities in TTC Kenji KORO TTC Next-Generation Home Network system WG Jeju, 13 – 16 May 2013 Standards for Shared ICT GSC17-PLEN-32 Highlight of Current Activities Standardization about Home Networking (HN) in Japan HEMS operation in Japan was required to specify at an early stage, so TTC specified several standard and technical reports as follows. Communication protocol (interface) under the layer of ECHONET Lite; • JJ-300.10: Home network Communication Interface for ECHONET Lite (IEEE802.15.4/4e/4g 920MHz-band Wireless) • JJ-300.11: Home network Communication Interface for ECHONET Lite (ITU-T G.9903 Narrow band OFDM PLC) TR-1043: Implementation guidelines of Home network communication interface Planning to study interworking between TR-069 and G.9973 for end device control Propose to SG13: Y.cloud-hemsarch: (Proposal for initiating study on architecture of the HEMS cooperating with the Cloud) Cooperation with the related SDOs and Fora ITU-T, BB-Forum, HGI, DLNA, UPnP, etc. MoU between TTC and ZigBee Alliance, Wi-SUN Alliance. Cooperation in Japan New Generation Network Promotion Forum in Japan: IP network WG: Research technical and application demands HATS: Interoperability test about NAT Traversal. GSC-17, Jeju / Korea 2 Standards for Shared ICT GSC17-PLEN-32 Strategic Direction TR-069 is well known as the technical specification entitled CPE WAN Management Protocol (CWMP), but interworking with HN internal apparatus is not sufficiently defined. About this problem, TTC will study the interworking between TR-069 and G.9973 for end device control. GSC-17, Jeju / Korea 3 Standards for Shared ICT GSC17-PLEN-32 Challenges Consider the cooperation between G.9973 and TR-069. Device UPnP/LLDP Device Home network topology information ACS CWMP (TR-069) Proxier HTIP HTIP Manager HTIP HTIP HTIP HTIP HTIP Agent Agent Agent Figure Sample of the information flow between ACS and HTIP(G.9973) Note: ACS (Auto Configuration Server) HTIP (Home-network Topology Identifying Protocol ) GSC-17, Jeju / Korea 4 Standards for Shared ICT GSC17-PLEN-32 Next Steps / Actions TTC will examine the cooperation about the access method to the HTIP information by CWMP. Propose to BBF, how to manage the HTIP information at ACS.
