Home Networking activities in TTC Document No: GSC16-GTSC9-02 Source: TTC Contact: Kenji KORO GSC Session: GTSC9 Agenda Item: 4.3: Home Networking Home Networking activities in TTC Kenji KORO TTC Next-Generation Home Network system WG

Highlight of Current Activities Standardization about Home Networking (HN) in Japan Now on 3rd stage of standardization Control and Operation: propose to ITU, Standardized Home-network Topology Identifying Protocol (JJ-300.00 -> G.9973) Considering to cooperate between TR-069 and G.9973 for end device control G.hn: Standardized of G.hn series for suitable in Japanese network environments New SWG started： The subject is to consider the system cooperation of the whole HN, especially the use-case demand from application. Cooperation with the related SDOs and Fora ITU-T, BB-Forum, HGI, DLNA, UPnP, etc. Cooperation in Japan New Generation Network Promotion Forum in Japan: IP network WG: Research technical and application demands HATS[1] in Japan 　　Tested NAT Traversal function between network and home equipment.

Strategic Direction Although TR-069 which is control from WAN was well known, but cooperation with HN internal apparatus is not sufficient. About this problem, we will examine to cooperate between TR-069 and G.9973 for end device control.

Challenges Confirm interoperability of Control and Operation: Standardized Home-network Topology Identifying Protocol (G.9973) and TR-069 Research the interference to Japanese Domestic wireless systems such as TV broadcasting, CATV, and Cellular from the new equipment related G.hn Standards （JT-G9960, JT-G9961, JT-G9972）.

Next Steps / Actions TTC will conduct the network middleware for the communication between access gateway and home terminals. Examination and standardization of sharing of Interface to achieve service on service platform. Service platform for several Applications. (DLNA, ECHONET…)
