IMS-Based Services – Network – Network Interface Definition R.1.1

Network – Network Interface Definition

September 2018

This document provides the i3 forum`s perspective on the definition of the Network-to-Network Interface (NNI) between multiservice IMS-based platforms focusing on voice and video services originated from fixed as well as mobile networks. The scope covers both the Network-to-Network Interface between a Service Provider and Int. Carrier and between two Int. Carriers.

It does not intend to duplicate other existing specifications or documents on the same issue, but to complement these documents with the perspective of the International Carrier members of i3 forum.
