Release Approach
Status and review of Release 1
Proposal

3. Release Approach FG NGN Standards IMS Beyond IMS
IMS has release based approach (already start Release 7)
FG NGN also agreed to get similar approach like “Release”
IMS (Release 6 based) would be incorporated into NGN Release

4. Release Approach Criteria for set up Releases in FG NGN
Target dates : Realization of NGN
Services and Capabilities (include Network and Control Capability)
Architecture, components and Specifications
(?)
End of 2006
I/F 2
End of 2005
I/F 1
NGN Release 1
NGN
Release 2
Services & Capabilities : S&C 1
Functional Arc. & Spec. : FA&S 1
IW and Interconnection : IAI 1
Migration : MIG 1
NGN
Release 3
S&C 2 = S&C 1+ A2
FA&S 2 = FA&S 1 + B2
IAI 2 = IAI 1 + C2
MIG 2 = MIG 1 + D2
FPS Based (?)

5. Release Approach Problem Status of current plan for NGN (?) (?) (?)
Role and position of IMS (Release 6) in NGN is not yet clear
But Release 1 mostly developed based on Release 1/TISPAN (IMS)
Concerns from non-Europe : NGN mainly for Mobile(?) and Europeans (?)
Views and Opinions from CJK : having further requirements (?)

Non Session controller based
Data communication services
Data retrieval applications
Push services
Information services, such as cinema ticket information, motorway traffic status, advanced push services, etc.
Online applications
Speech-enabled services
Remote control/tele-action services
Messaging services such as SMS, MMS, etc
Broadcast/Multicast Services
Mobility
limited to the ability of a terminal to be moved to different access points
support nomadism
Not require to support hand-over of communications sessions between access networks
No requirement to prevent continuous terminal mobility within an access network
Interconection

9. Proposal Release 1 mainly leaded by European requirements
Concern about FG NGN Releases
Release 1 mainly leaded by European requirements
Input for the Release 1 could be closed at November
Need check gaps and further requirements from CJK
Specially Network aspects include control features could be developed from CJK
NGN FG only have “Release 1” plan : plan for future releases such as Release 2 and Release independent etc. are not clear yet
Optic infrastructure based requirements would be next release (Release 2 ?)
Initiate Release 2 from CJK
