Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN); Technical Report on NGN National IP Interconnection
|Publication Date:||1 April 2012|
The present document provides guidance for handling IMS-based NGN national IP interconnection details.
Interconnection of NGNs represents a broad area of study including such areas as signalling interconnection, media interconnection, routing, address resolution, security, charging and network management. However, as with most aspects of the NGN, there are many Standards Development Organizations (SDOs) and industry bodies that are working on this topic.
As organizations such as ITU-T, 3GPP, GSMA and the i3 Forum do focus on overarching IP interconnection specifications and agreements, a gap on guidelines for the handling of national IP interconnection was identified. The present document is intended to fill this gap for IMS based NGN national IP interconnection in co-relation with the IMS approach of 3GPP.
