ETSI ETSI TR 124 969 V14.0.0 (2017-04)73GPP TR 24.969 version 14.0.0 Release 141 Scope The purpose of th

32、e 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, requi

33、red 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

34、-charge aspects are addressed as far as SIP signalling is concerned.
