32、ase 131 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

33、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 perspec

34、tive of an NGCN site. Advice-of-charge aspects are addressed as far as SIP signalling is concerned. The present document is based on 3GPP TS 24.229 12. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - Refe

35、rences are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies.

36、GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 IETF RFC 3261 (2002): “SIP: Session Initiation Protocol“. 2 3GPP TS 22.519: “; Business communication requirements, stage 1“. 3 3GPP TS 24.525: “Business tr
