ITU-T M.3340 (05/2009) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field
10、of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing
11、 telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by
12、 the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate bo
13、th a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when a
14、ll of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY R
15、IGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by
16、ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation.

ITU-T M.3340 (05/2009) Introduction This Recommendation contains the B2B/C2B interface framework for NGN service fulfilment and assurance management. The fram
21、ework of the interface across several administrative domains in the NGN service supply chain is provided. In a NGN service supply chain, the service customer, the service provider, and the network operator interwork with each other for service provisioning, service assurance, and service billing. Se
22、rvice management information is exchanged across interfaces which may be client-to-service-provider or service-provider-to-service-provider interfaces and may represent inter-jurisdictional communications. The scope of this Recommendation provides an interface framework for NGN service fulfilment an
23、d assurance management across several administrative domains. Rec.
