Interworking between NGN and legacy IP-based networks Michael Kim yjkim@tta.or.kr Document number Beijing, China 22-24 July 2009
Contents background Contents of Y.ipev New contents of Y.ipev Conclusion
1. background • Previous study period, Y.ipev, “the IP evolution to NGN” was allocated Q.7/13 and has been developed. • At the SG13 meeting on Jan Geneva, Y.ipev was updated and allocated to Q.12/13. • At the Q.12/13 Rapporteur’s meeting on June 22-26 Geneva, the meeting has requested the restructuring of current draft Recommendation Y.ipev in the name of “Interworking between NGN and legacy IP-based networks”
2. Best effort IP network evolution to NGN • 1. Scope • 2. References • 3. Definitions • 4. Abbreviations and acronyms • 5. Conventions • 6. Best Effort IP network evolution • 7. Network evolution architecture • 8. Evolution Scenario • 8.1 Phase 1: CNs Interworking • 8.2 Phase 2: ANs interworking • 8.3 Phase 3: CN integration • 8.4 Phase 4: CPN and AN integration • 9. Interworking consideration
2.2 Evolution Scenario Phase 1: CNs Interworking Phase 2: ANs interworking Phase 3: CN integration Phase 4: CPN and AN integration
3. Interworking between NGN and legacy IP-based networks • General description of legacy IP-based networks • Legacy IP networks as other networks • Features of legacy IP-based networks • Specific requirements of interworking with legacy IP-based networks • Support of NGN services • Support of end to end QoS • Support of mobility • Support of security • Architectural considerations for interworking • Aspects of service interworking between NGN and legacy IP-based networks • Aspects of network interworking between NGN and legacy IP-based networks • Gateway functions for interworking • Interworking scenarios between NGN and legacy IP-based networks • Classification of interworking cases • Interworking scenarios for each case
4. Conclusion • Interworking with legacy IP network is important things to consider • More contributions for Y.ipev are required
