9、ternational Telecommunication Union (ITU) is the United Nations specialized agency in the field 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,

10、 operating and tariff 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 tu

11、rn, 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 information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOT

12、E In this Recommendation, 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,

13、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 other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not

14、 suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU 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

15、evidence, validity 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, whi

16、ch may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

34、 conformance to this document is to be claimed. The keywords “is recommended“ indicate a requirement which is recommended but which is not absolutely required. Thus this requirement need not be present to claim conformance. In the body of this Recommendation and its annexes, the words shall, shall n

35、ot, should, and may sometimes appear, in which case they are to be interpreted, respectively, as is required to, is prohibited from, is recommended, and can optionally. The appearance of such phrases or keywords in an appendix or in material explicitly marked as informative is to be interpreted as h

36、aving no normative intent. 6 Overview As an important part of telecommunication management, service management implements all of the functionalities necessary for the management and operations of communications and information services required by or proposed to customers. Rec. ITU-T M.3371 (10/2016

37、) 3 It includes service fulfilment, service assurance and service billing through the lifecycle of the service: service fulfilment: To fulfil the resource capacity and service quality requirements of customers, maintain the readiness of the resource and service capacity, provide function and interfa

38、ce to customers for the access and consumption of service; service assurance: To support the function and process of service assurance, includes service level management, service incident and problem management, service monitoring and reporting management; service billing: To support the function an

39、d process of service billing. With the convergence of information technology (IT) and communications technology (CT) industries, cloud computing is being adopted in telecommunication infrastructures. Telecommunication operators deliver cloud services, and also apply cloud computing technologies for

40、the optimization of their telecommunication service platforms and telecommunication support systems. ITU-T M.3070 has defined a service management interface (SMI)-based common model for end-to-end (E2E) cloud computing management, which is described in Figure 6-1. In this model, a cloud-aware teleco

41、mmunication management system can manage cloud-based facilities through the management interface “I1“ which can correspond to a set of SMIs. Figure 6-1 Common model for E2E cloud computing management, with telecommunication operator acting as a CSP (after ITU-T M.3070) A cloud-aware telecommunicatio

42、n management system can manage both telecommunication services and cloud services in a consistent manner. Although the management layering could be the same as the traditional telecommunication management layering, with the introduction of cloud computing, there are still new requirements for cloud-

43、aware telecommunication management. This Recommendation addresses the requirements of comprehensive service management in a cloud-aware telecommunication management system. The relationship between cloud service management and service management in a cloud-aware telecommunication management system i

44、s also illustrated in Figure 6-1. The cloud service management is located in business support system(BSS)/operations support system (OSS) (marked by the red rectangle in Figure 6-1) which belongs to the cloud service provider (CSP), and the service management in the cloud-aware telecommunication man

45、agement system (marked by the yellow 4 Rec. ITU-T M.3371 (10/2016) rectangle in Figure 6-1) which belongs to telecommunication operator. As an important aspect of cloud service management, cloud service lifecycle management (see ITU-T Y.3522) is also located in BSS/OSS which belongs to CSP. 7 Genera

46、l requirements for service management in cloud-aware telecommunication management system As a cloud-aware telecommunication management system, the difference with a traditional telecommunication management system is it could support comprehensive management for telecommunication services, cloud serv

47、ices and TC-hybrid services which consist of both telecommunication and cloud service components. In a cloud-aware telecommunication management system, the general requirements include: it is required that service management provides service catalogue and service inventory management functionality f

48、or telecommunication service, cloud service and TC-hybrid service; it is required that service management supports the on-demand and automated service provisioning modification and termination for telecommunication service, cloud service and TC-hybrid service; it is recommended that service manageme

49、nt supports the E2E quality assurance of telecommunication service, cloud service and TC-hybrid service, and provide high levels of reliability and availability according to the service level agreement (SLA); it is recommended that service management supports charging for telecommunication service, cloud service and TC-hybrid service, according to use time, bandwidth, resource usage and any combination of these; it is recommended that service management supports monitoring, auditing and reporting for tele
