M.3050.0 (03/2007) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunicat
10、ions. 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 telecommunications on a worldwide basis. The World Telecommunicatio
11、n 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 the procedure laid down in WTSA Resolution 1. In some areas of info
12、rmation 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 both a telecommunication administration and a recognized operating age
13、ncy. 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 all of these mandatory provisions are met. The words “shall“ or some
14、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 RIGHTS ITU draws attention to the possibility that the practice or im

ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development proc

33、ist in the decomposition of the management requirements into manageable subsets and to encourage the re-use of solutions. ITU-T M.3010 provides an overall architectural framework and, in particular, includes a logical layered architecture (LLA) that separates levels of abstraction in managing networ
34、k elements, networks, services, etc., and relates them to the management service/function approach. ITU-T M.3010 organizes TMN functions into horizontal groupings called logical layers and describes the relationships between them to deal with TMN complexity. The LLA consists of five layers (BML, SML
35、, NML, EML, NEL) with business management at the top, service management ITU-T Rec. M.3050.0 (03/2007) 3 the second layer, network management the third layer, element management the fourth layer, and the network elements at the bottom. In the first TMN Recommendation on the management service/functi
36、on approach, a set of TMN application functions were identified, building upon the fault, configuration, accounting, performance and security (FCAPS) management categories that are described in ITU-T M.3400. In order to support the wide variety of management activities including planning, installati
37、on, operations, administration, maintenance, and provisioning of telecommunications networks and services, the concepts of telecommunications managed areasand TMN management services were developed and are described in ITU-T M.3200. The telecommunications managed areas relate to the grouping of tele
38、communications resources being managed and the management services relate to the set of processes needed to achieve business objectives (i.e., management goals). It has been accepted that flexibility is required in the definition of TMN management services to enable additional requirements to be acc
39、ommodated as they are identified (see ITU-T M.3200). The TMN management services are described from the TMN users perspective and are independent of the protocols, messages and information models chosen. The management services are comprised of management functions and specify offerings fulfilling s
40、pecific telecommunications management needs. Management functions are grouped together and referred to as a management function set. The library of general management function sets and their management functions members can be found in ITU-T M.3400, categorized according to their FCAPS application a
41、nd specified together with generic end-to-end flow scenarios that relate them to management services and managed areas according to ITU-T M.3200 and TMN logical layers according to ITU-T M.3010. The resulting scheme consists of horizontal groupings into layers and vertical groupings into functional
42、flow-through areas. In the interface specification methodology ITU-T M.3020, each interface specification addresses one or more management service(s) defined in ITU-T M.3200. A specification may support part of or one or more management services. In describing the requirements for an interface, the
43、functions identified may reference those defined in ITU-T M.3400 or specialize one or more of them to suit a specific managed area, or new functions may be identified as appropriate. 6 The business process approach The business process approach has built on the concepts of management services and fu
44、nctions in order to develop a reference framework for categorizing all the business activities that a service provider will use. This is done through a business-oriented definition of each area of business activity, in the form of a process view that describes the service providers enterprise in a t
45、op-down, structured way with progressive decomposition to expose increasing detail. The individual process elements that are identified can then be positioned within a model for analysis of organizational, functional and other relationships, and can be combined within process flows that trace activi
46、ty paths through the business. This process-oriented perspective can be related to the functional view provided elsewhere in TMN to allow the relevant management and resource/network capabilities to be linked with the business needs that they support. This is further discussed in clause 7 below. The
47、 vehicle for expressing this process view of the service provider is the enhanced Telecom Operations Map (eTOM) business process framework, developed by the TeleManagement Forum. The eTOM framework can serve as the blueprint for standardizing and categorizing business 4 ITU-T Rec. M.3050.0 (03/2007)
48、 activities (i.e., process elements) that will help set direction and the starting point for development and integration of business and operations support systems (BSS and OSS, respectively). In the context of TMN, the eTOM framework provides the business-oriented view of service provider requireme
49、nts that management services and functions need to support, and the mapping from individual eTOM processes to management functions, and vice versa, is documented to assist and support the application of both these processes and functions within management solutions. By including the eTOM framework within TMN, it is intended that the telecommunication industry will have clear information and guidance on linking the eTOM process view with other areas of TMN, and will be able to leverage the
