Support convergences over NGN
Global Standards Collaboration (GSC) 14

• Chaesub LEE, ITU-T SG13 Chairman,
• followed by

NGN Signalling and Testing
Wei FENG, ITU-T SG11 Chairman
2
Highlight of Current Activities

• Status of ITU-T SG13 NGN developments

3
Strategic Direction

• Using connectivity from networks is becoming
  essential for all human life today and will have
  more influence in future life
• Convergence over NGN is one of the best way to
  mitigate Climate Change, because NGN provide
  common networking platform for convergences
• Develop capabilities to support convergences
• Detailed Functions in Service Stratum 4
  approaches are now discussed since May NGN-GSI
  Event
• Support Internal Convergences
• FMC/MM Consent MMCF (Y.2018) and IMS-FMC
  (Y.2808)
• IPTV Content delivery Storage (Y.CDS), Info.
  Delivery Framework (Y.IPTV-IDF), Y.IPTV-TM
  (Traffic Manag.) and IPTV Interworking
  (Y.iptvintwrm)
• Support External Convergences Networked Vehicle
  (Y.NGN-Vehicle), Multi. Serv. Cap. in HN
  (Y.msc-hn-ngn)

4
Challenges

• In case of FMC/MM
• Level of supported services Voice, Data,
  Streaming, Video
• Level of supporting capabilities e.g. Seamless
  Handover
• Need consideration between above two
• In case of IPTV see another Doc.
• In case of Service Stratum
• Integrated vs. Distributed and Unified vs.
  Diverged
• Collaboration with Service aspect development
• In case of external convergences
• Clear boundary of NGN involvement
• Collaboration with other relevant groups

5
Next Steps/Actions

• ITU-T SG13 should more efforts to develop
  detailed recommendations for supporting FMC and
  MM with identifying target service such as
  Seamless Voice services over FMC etc.
• ITU-T should accelerate development of relevant
  protocols to support FMC and MM collaborating
  with related SDOs
• Joint activities with service related experts
  group like SG16 should be encouraged for better
  development of Service Stratum in NGN
• And it is also recommended joint activity with
  relevant SDOs to develop recommendations for
  supporting External Convergences

NGN Signalling and Testing

• Wei FENG
• ITU-T SG11 Chairman

7
ITU-T SG 11 role and mandate

• Responsible for studies relating to signalling
  requirements and protocols, including those for
  IP-based networks, NGN, mobility, some multimedia
  related signalling aspects, ad hoc networks
  (sensor networks, RFID, etc.), QoS, and
  internetwork signalling for ATM, N ISDN and PSTN
  networks.
• This also includes reference signalling
  architectures and test specifications for NGN and
  emerging networks (e.g., USN).
• SG 11 has three lead study group responsibilities
  on signalling and protocols, on intelligent
  networks and on test specifications.

8
Highlight of Current Activities

• SG 11 has completed NGN Protocol Set 1 which
  constitute a fundamental basis for initial
  implementations of NGN release 1
• Signalling architecture for the NGN Service
  Control Plane (Q.3030)
• Signalling requirements at (SUP-FE) -
  (I/S-CSC-FE) i/f (Q.Sup.54), (AS-FE) (S-CSC-FE)
  i/f (Q.Sup.55), Organisation of NGN Service User
  Data (Q.Sup.56), IEPS communications (Q.Sup.57
  and Amendments to ISUP, BICC and DSS2 protocols)
• Interface control protocols for RACF
  (Q.3300-series)
• Rs, Rp, Rc, Ri and Rw interface
• NGN NNI and UNI signalling profiles (Q.3401 and
  Q.3402)
• Signalling requirements and protocol profiles for
  CRBT and CRT services (Q.3610 and Q.3611)
• NGN testing for the support of the compatibility
  of NGN technical equipment and services (Q.3900,
  Q.3901 and Q.3902)
• EAP-based security signalling protocol
  architecture (Q.3201)
• Authentication protocols for interworking among
  3GPP, WiMax and WLAN in NGN (Q.3202.1)
  Requirements and protocol for the interface
  between a Transport Location Management PE and a
  Policy Decision PE (Ru Interface) (Q.3223)

Strategic Direction

• Accelerate study on
• Monitoring parameters for NGN protocols
• Service test specification for NGN
• QoS tests specification for NGN
• USN and RFID test specification
• Coordination of work on Emergency Communications
  within an NGN environment
• Security Coordination For NGN Protocols
• Consider, in collaboration with ISO/IEC JTC 1/SC
  6 standards for end-to-end multicast

10
Challenges

• More coordination and cooperation with other SDOs
  such as 3GPP, IETF, ETSI, ATIS, IEEE, etc.
• Complementary and consistent with outputs from
  other SDOs.
• More work focusing on testing, QoS, Network
  attachment, Service and application and Emergency
  Telecommunications, etc.
• New signalling and protocols work related to
  IPTV, M2M, etc.
