1 Scope

The objective of this document is to address the Inter-IMS Network to Network Interface (II-NNI) consisting of Ici and

Izi reference points between IMS networks in order to support end-to-end service interoperability.

The present document will address the issues related to control plane signalling (3GPP usage of SIP and SDP protocols,

required SIP header fields) as well as other interconnecting aspects like security, numbering/naming/addressing and

user plane issues as transport protocol, media and codecs actually covered in a widespread set of 3GPP specifications. A

profiling of the Inter-IMS Network to Network Interface (II-NNI) is also provided.

Charging aspects will be addressed as far as SIP signalling is concerned.
