ITU-T R2 new services/capabilities
• Service stratum related capabilities
– RFID; Describes RFID applications. Requirements for NGN will be
added in the future
– Open Service Environment Capabilities: Describes integrated ANI
(application network interface) including 3GPP OSA. Requirements
for NGN will be added in the future
• Transport stratum related capabilities
– FMC; documents on requirements, IMS-based architecture, Service
scenario for NGN with PSTN-based access networks are under
discussion
– Multicast with MPLS-based QoS support: Requirements,
architecture overview, information flow are under discussion
• Application related services
– IPTV discussion is moved to Focus Group on IPTV (~2006/07)
• Most new services are proposed by Korea and China in ITU-T

TISPAN NGN Release 1 and Release 2
NGN Release1 published in December 2005 (60 documents).
NGN Architecture, PSTN/ISDN emulation & PSTN/ISDN simulation are main outputs.
NGN Release 2 started in February 2006.
Service expansion (IPTV, etc.) and architecture enhancement are main targets.
NGN Release 2 (2006 2007)
NGN Release 1 (2004 - 2005)
-NGN Architecture
(IMS, RACS, NASS, etc.)
-PSTN emulation & simulation
-xDSL is the main access
considered
Main players of TISPAN are operators
and vendors with wireline business,
such as BT, FT, DT, TI, Ericsson,
Siemens (+Nokia), and Alcatel.
New players have appeared
in NGN release 2, such as
Cisco and Microsoft.
-IPTV( IMS based & Non- IMS based)
-RACS Release 2, NASS Release 2
-Fixed Mobile Convergence (FMC)
-Corporate Networks
-Home Networks,
-Advanced Charging etc.
-Architecture

-Service
Expansion
Cooperation with other SDOs is emphasized
to proceed NGN release 2.
