  2. Contents Status of Requirements What are next? How going to next? Conclusion

  3. 1. Status of Requirements • Services expected to be supported in NGN Release 1 • PSTN/ISDN Emulation and Simulation services • Multimedia services • Data communication services (including VPNs) • Public Interest Services • NGN is not intended to preclude access to the Internet • Services expected to be supported in NGN Release 2 • IPTV services • Managed delivery services • NID related services • Services using tag-based identification • Ubiquitous Sensor Network services • Additional multimedia services • Visual surveillance services • Multimedia communication centre services • Enterprise services (NGN support of services for enterprises) • Virtual Leased Line, Business Trunking, Hosted services • Home network services (support of services in HN environments)

  6. 2. What are next? Expansion of Quality of Service concept • NGN support QoS but with very limited scope: only bandwidth but mostly one capability: e.g. Best effort • Even “Guaranteed mode” is developed but “No Granularity” • It is required to support “Granularity” of Bandwidth and diversity of QoS into NGN 2M 8M Best Effort 100M

  7. 2. What are next? Expansion of Quality of Service concept Meaningful QoS over NGN Quality of Mobility Quality of Media Quality of Personalization Quality of Security • RT Mobility control • Service Continuitycontrol • Security support • End-End QoS • QoS Monitoring • Service Policy handover • One-stop Service • Service AAA • Personalized serviceOpen/Control • Network AAA;Terminal, User,Mobility, Access etc.

  8. 3. How going to next? Q5 REQ Q12 Q4 Q8 Q7 Q16 OR Questions Requirements

  9. 4. Conclusion • Climate change aspects should be one of the key subjects • NGN should be enough to support various services • IPTV should be maximize benefit of IP • NGN/IPTV also should provide dynamic features • Expansion of “Quality of Service” concept Take into account“Time to Market”
