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.CD&S), Info. Delivery
Framework (Y.IPTV-IDF), Y.IPTV-TM (Traffic Manag.) and
IPTV Interworking (Y.iptvintwrm)
 Support External Convergences: Networked Vehicle (Y.NGNVehicle), Multi. Serv. Cap. in HN (Y.msc-hn-ngn)

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

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
Fostering worldwide interoperability
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.
Fostering worldwide interoperability
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), (ASFE) – (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)
Fostering worldwide interoperability
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
Fostering worldwide interoperability
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.
