Next Generation Networks offer dedicated subsystems for each task to be fulfilled within the overall architecture defined in TISPAN NGN Release 1 [1]. There exist different subsystems for PSTN/ISDN emulation, streaming services and the 3GPP driven IP Multimedia Subsystem (IMS) which has been adapted to the NGN architecture. In NGN Release 2.0 IPTV shall be integrated into that architecture to support extended streaming services for next generation television. Current developments within ETSI TISPAN show two different approaches when speaking of the integration of IPTV services into the NGN: One IMS-based solution that relies on IMS/SIP signaling for new services and a non-IMS black box approach as an independent NGN subsystem. Our research activities are focused on the IMS-based activities and aim on the development of a reference architecture and on the service definition towards the now starting ETSI TISPAN standardization activities. This work shall introduce our architecture approach and evaluation based on precedent scenario and requirement analysis.
