ETSI ETSI TR 124 969 V15.0.0 (2018-06)73GPP TR 24.969 version 15.0.0 Release 151 Scope The purpose of the present document is to give an implementation guide to the relevant Common IMS specifications and

34、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

35、 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 o
