Fixed network core IMS mapping (TISPAN)

Fixed network core IMS mapping (TISPAN) 

Please click here to see the table of the ETSI publications relating to core functions of the IP Multimedia Subsystem (IMS) used by the Next Generation Network standardized within ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN).


Because of different working methods between TISPAN and 3GPP, NGN Release 1 (R1) and Release 2 (R2) publications are transferred under separate 3GPP TS numbers. Where further development is envisaged within the Rel-8 timeframe, a further number, 2x.6xx, has been allocated.


In general, TISPAN documents are transferred in an already-frozen state, and only essential maintenance is envisaged on the 3GPP 2x.4xx and 2x.5xx TSs.
