Service Customized Multimedia Ring, Converged Web Browsing Service


Using connectivity from networks is becoming essential for all human life today and will have more influence in future lifeConvergence over NGN is one of the best way to mitigate Climate Change, because NGN provide common networking platform for convergencesDevelop capabilities to support convergencesDetailed Functions in Service Stratum: 4 approaches

are now discussed since May NGN-GSI EventSupport 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.NGN-Vehicle), Multi. Serv. Cap. in HN (Y.msc-hn-ngn)

Strategic Direction


ChallengesIn case of FMC/MMLevel of supported services: Voice, Data, Streaming, VideoLevel 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 convergencesClear boundary of NGN involvement

Collaboration with other relevant groups


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 SDOsJoint 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


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.

ITU-T SG 11 role and mandate


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)

Highlight of Current Activities


Accelerate study on:Monitoring parameters for NGN protocolsService test specification for NGNQoS tests specification for NGNUSN and RFID test specificationCoordination of work on Emergency Communications within an NGN environmentSecurity Coordination For NGN ProtocolsConsider, in collaboration with ISO/IEC JTC 1/SC 6 standards for end-to-end multicast

Strategic Direction


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.
