Strategic Direction
Current Broadband provides huge bandwidth
But mostly with one capability: e.g. Best effort
Even “Guaranteed mode” is developed but “No
Granularity”
QoS is also very limited: only bandwidth
It is required to support “Granularity” of
Bandwidth and QoS into broadband
2M
8M
Best Effort
100M

Challenges
Standard for supporting Granularity
Extension of QoS concept
Meaningful QoS over NGN
Quality of
Personalization
• One-stop Service
• Service AAA
• Personalized service
Open/Control
Quality of Security
Quality of Mobility
Quality of Media
• Network AAA;
• RT Mobility control
• Service Continuity
control
• Security support
• End-End QoS
• QoS Monitoring
• Service Policy handover
Terminal, User,
Mobility, Access etc.
Fostering worldwide interoperability

Next Steps/Actions
Further development of standard supporting
“Granularity”
Extension of QoS concept to meet diverse user
and service requirements
This is a way to contribute for mitigating climate
change with effective resource arrangements and
usage
