Next-Generation Home Network system WG
Geneva, 13-16 July 2009
Fostering worldwide interoperability
Highlight of Current Activities

Standardization about Home Networking (HN) in
Japan
Now on initial stage of standardization




QoS: Investigated several existing recommendations
Data Model: Analyzed dependencies on applications
Operation: Analyzed the functional requirement
Research: Applications realized in NGN
Research the physical interface including 802.XX, access
point base station(Femto) and ZigBee.
Plan to submit proposal to ITU-T SG15, SG16,etc.
Cooperation with the related SDOs and Fora
ITU-T, HGI, BB-Forum, DLNA, UPnP, etc.
Cooperation in Japan
Next Generation IP Network Promotion Forum in Japan:
Home Network WG: Research technical demands
HATS[1] in Japan
Established new WG for interconnection verification
Note[1]: Non profit organizations for inter-operability

Strategic Direction
Architectures have been proposed by several bodies such as
ITU and Fora.
But there are no consistent suite of Recommendations from
WAN to HN dealing with the following items.
Maintenance (In case of the problems or failure has occurred)
Device setting
Device composition confirmation
In Layer 2/3, there are many candidate protocols.
But for the management of home device, some modification
will be required.
Isn't cooperation necessary on this respect among PSOs?

Challenges
Conduct systematic technical test composed of
WAN, Access, Home-GW, and Intra-HN in close
cooperation with Fora in Japan.
Operation from WAN to HN
Energy saving in the HN
Home Security
Cable application
Confirm total interoperability.
Examination of device list in HN
Examination of a model in HN
Cooperation items with other standardization bodies
Data models
Appliance device control (TV etc.)

related use cases.
NGN application
Contents transmission/reception
Click to Call
Multi-media communication
Etc.
Network consumer electronic devices management
Maintenance
Device setting
Device composition confirmation
Confirm total interoperability.
