7、s Recommendation differs from existing approved Recommendations on trouble management in that NGN requires product and service flexibility and extensions introduced by new technology for NGN. Trouble type is also configurable and extensible by either the service provider or service customer to suppo
8、rt new products and services. These extensions are introduced to support peer-wise, local, national and regional requirements introduced and described in ITU-T Recommendation M.3050.2 for supplier/partner relationship management introduced by the NGN value-chain. This is needed to support regulatory

10、c. M.3343 (01/2007) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and t
11、ariff questions and issuing Recommendations on them with a view to standardizing 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 Reco
12、mmendations on these topics. The approval of ITU-T Recommendations is covered by 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 Recomm
13、endation, the expression “Administration“ is used for conciseness to indicate both 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., interoperab
14、ility or applicability) and compliance with the Recommendation is achieved when all 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 com
15、pliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS 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, validi
16、ty or applicability of claimed Intellectual Property Rights, whether asserted by 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 requir
17、ed to implement this Recommendation.

20、ec. M.3343 (01/2007) Introduction This Recommendation contains the requirements and analysis for the trouble administration function for the business-to-business (B2B) and customer-to-business (C2B) interfaces. From time to time all systems, including communications networks, develop problems or mal
21、functions, referred to in this Recommendation as “troubles“. A “trouble“ in a communications network is a problem that has an adverse effect on the quality of service perceived by network users. When a trouble is detected, possibly as a result of an alarm report, a trouble report may be entered by a
22、 user or the system may raise a report automatically. Management of that trouble report is necessary to ensure that it receives attention and that the trouble is cleared to restore the service to its previous level of capability. At the time of a trouble, a network may have been interworking with an
23、other network to provide a service and the problem or malfunction may be due to the other network. Therefore, it may be necessary to exchange trouble management information between management systems across interfaces which may be client-to-service provider or service provider-to-service provider in
24、terfaces and may represent inter-jurisdictional, as well as intra-jurisdictional, boundaries. In addition to exchanging information on trouble that has already been detected, advance information on service inaccessibility may also need to be exchanged. Thus, a service provider may need to inform a c
25、ustomer of future service inaccessibility (because of planned maintenance, for example). The scope of this Recommendation includes all of the above processes for exchange of management information for NGN to support the B2B and C2B interfaces. The NGN introduces the requirements for the extensibilit
26、y and configurability of the trouble types to address new and evolving IMS services, the definition of these extensions is for further study. ITU-T Rec. M.3343 (01/2007) 1 ITU-T Recommendation M.3343 Requirements and analysis for NGN trouble administration across B2B and C2B interfaces 1 Scope This
27、Recommendation contains the requirements and analysis for the business-to-business (B2B) and customer-to-business (C2B) interfaces of trouble administration for NGN. It assumes a multi-service provider environment and is aimed at trouble administration functions to support the deployment of NGN and
28、includes both the B2B and C2B interfaces. B2B/C2B interface is a synonymous term to X Interface. Figure 1-1 shows the relationship of this Recommendation to existing and as yet undefined documents for service assurance management. It shows the architecture for NGN service assurance management.

30、surance/trouble management Trouble administration consists of processes utilizing trouble report management, testing management, appointment management and SLA management. This Recommendation and the current ITU-T X.790 are specific to trouble report. Functions for testing of the service or transpor
31、t stratum, appointment management and SLA management are outside the scope of this Recommendation. Trouble administration will require all the functions defined in this Recommendation and the other three Recommendations to provide a complete set of functions. Third-party request/response operations
32、are dependent upon the privacy business rules defined in the SC/SPs contract and consequently are considered out of scope for this Recommendation. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of
33、this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and ot
