1 Scope
The purpose of the present document is to give an implementation guide to the relevant Common IMS specifications
and functions used in the interconnection of a Next Generation Corporate Network site (NGCN site) to the NGN.
The present document addresses control plane signalling (usage of SIP and SDP protocols, required SIP headers) as
well as other interconnecting aspects like security, numbering/naming/addressing and user plane issues such as transport
protocol, media and codecs actually covered in a widespread set of 3GPP and ETSI TISPAN specifications, as seen
from the perspective of an NGCN site.
Advice-of-charge aspects are addressed as far as SIP signalling is concerned.
The present document is based on TS 124 229 Release 7 [i.12] as modified by ES 283 003 Release 2 [i.15].
NOTE: Some errors corrected in TS 124 229 Release 8 and 9 are already taken into account in the present
document.
