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
• HATS1 in Japan
• Established new WG for interconnection
  verification

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?

4
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.)

5
Next Steps/Actions

• Define the control and operation specifications
  for 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.
• WAN to HN operational interoperability test in
  HATS
