TISPAN is … the home of NGN standards

5th ETSI Security Workshop - Sophia-Antipolis, 20-22 January 2010

TISPAN NGN Releases NGN Release 1: (December 2005)

Adopts the 3GPP IMS standard for SIP-based applications, and adds further functional blocks and subsystems to enable fixed access to IMS and to handle non-SIP applications

NGN Release 2: (April 2008) Release 1 enhancements (transfer of IMS enhancements and PSS to 3GPP) PSTN/ISDN Emulation – analogue and ISDN New topics: IPTV, Home Networks, Corporate Networks

NGN Release 3: (ongoing, target for stage 3: Mid 2010 with some exceptions) Improvement of several aspects introduced in the previous Releases, such as:

• IPTV service evolution • IP Network to Network interconnection • Home Network interconnection

New topics:-CDN Feasibility studies: P2P, Interactions RACS – Home networks
