Title of Presentation:
NGN NNI signalling profile
In order to spread the Next Generation Networks smoothly while retaining a high possibility of
interoperability among different carriers, it is very important to study a signalling profile at the
Network-to-Network Interface (NNI). This presentation examines the service-level signalling (i.e.,
SIP and SDP description) profile for the NNI, as well as the related standardization activities.
