8、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,
9、 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
10、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
11、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 e
12、.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

ITU-T M.3345 (05/2009) Introduction In the telecommunications market, most service providers are facing a business transformation produced by the open-market transition initiatives of regulatory bodies, result
19、ing in the need to lower their costs and increase their responsiveness to customers. Service providers need to: offer more flexible service choices to the customer/user; provide greater customer/user involvement in managing their service; increase the quality of interaction between the customer/user
20、 and the service provider; increase the service availability; provide customers/users with self-help in lifecycle operations of the service (i.e., from pre-order to decommissioning); and reduce the service providers costs of operation. Self-service capabilities offer reduced operation costs for serv
21、ice providers and enhanced quality of experience (QoE) to the customer. Self-service enables the service provider to maintain high service quality and lower operations cost. By empowering customer/user to manage his/her own services, the service provider drives up the QoE for the customer/user and e
22、nhances customer loyalty. The purpose of this Recommendation is to define the self-service management requirements and provide a base self-service management implementation for all types of telecommunication services (traditional network and telecommunication, NGN, etc.). The self-service management
23、 is applicable to service provider, network operator, and content providers operations support systems for the whole lifecycle processes. In this Recommendation, self-service can be applied to all phases of the service lifecycle from pre-order to termination and transition. NOTE Content providers al
24、so benefit from enhanced customer self-service experience. Customers may use self-service to browse, select and subscribe to content from product catalogues without involving directly the content provider. Rec.

25、nt 1 Scope This Recommendation defines the requirements, functional architecture and the concepts for self-service management. The self-service management functions covered in this Recommendation include customer relationship management, fulfilment, assurance, and billing. The applicability of self-

45、roduction 5.1 General Self-service in telecommunications is generally a new kind of service from both the customers and users perspective. This service provides new capabilities, features and benefits in service for the customer/user. By transferring management responsibility for the use of the serv
46、ice to the customer, self-service establishes a customer-facing interface for the services OSS. The service provider benefits from reduced operational costs and a customer-perceived increase in ease of use and in the quality of service. Self-service may be used differently by different customers: in
47、dividuals, family members, enterprise authorized users, or other self-service users. Self-service users may be either a manager within a customer organization, who manages the service directly, or other users authorized to manage some service instances. Users duly authorized to perform management op
48、erations on the service are SSM authorized users. Users who cannot change any aspect of the service are called SSM users. SSM users may only execute the functions enabled by the authorized users. Authorized users are not allowed to propagate authorizations. 4 Rec. ITU-T M.3345 (05/2009) Self-service
49、 management provides management functions for both the telecommunication network and services at a SSM actors request and provides a more efficient interaction between SSM actors and service providers. As an example, interactions performed by the SSM actor include user initiated ordering, service inquiry, billing inquiry, trouble reporting, maintenance oversight and management, performance reporting and management, and network management for resource intensive services. The goal of SSM is to enable zero-touch intera
