Information and Communications Technology (ICT) standardisation is part of the general standardisation activities, and contributes to policy objectives to improve the competitive
15、ness of European industry, as specified in the Lisbon strategy. The legal basis for European standardisation and standardisation policy, including the ICT domain, is Directive 98/34/EC i.4. One of its main elements is the formal recognition of three European Standards Organisations (ESOs), CEN, CENE
16、LEC and ETSI, active in various degrees in the ICT domain. Standards produced by the three ESOs and resulting from an open consensus building process are by nature voluntary and non binding technical documents. The standardization work described in the present document was funded by the European Com
17、mission, Enterprise and Industry Directorate-General, as part of the 2009 ICT Standardisation Work Programme and executed by ETSI. The present document has been produced within the ETSI Special Committee USER GROUP (USER) by the Specialist Task Force (STF) 375. Several documents provided by European
18、 Telecommunications regulatory bodies have been used to develop the present document. They are detailed in TR 102 847 i.3. It is important to understand that conformity assessment takes place in the wider environment of accreditation principles as defined in European Community regulation No 765/2008
19、 setting out the requirements for accreditation and market surveillance relating to the marketing of products and repealing Regulation (EEC) No 339/93 i.2. Introduction A significant difference rate between theoretical and actual bills has been identified by several parties in the current metering a
20、nd billing processes operated by service providers. Several service providers, administrations and users associations have intended to reduce this difference rate in implementing rules in order to make users more confident in the reliability of their bills. Nevertheless, due to the complexity of thi
21、s issue and in absence of any available formal standard in this area, the current practices are hindered by significant limitations. The purpose of document TS 102 845 1 is to fulfil the gaps of the current practices in order to provide a reference that can be used for a continuous and trustworthy c
22、hecking-up on metering and billing processes. Such a checking is expected to contribute to a continuous quality improvement of metering and billing processes. In order to provide evidence that metering and billing verification is conducted according to TS 102 845 1, it will be usefull for a service
23、provider to have its verification process audited by an independent party, that will formally assess the conformity of its checking-up on metering and billing with the technical specification. The purpose of present document) is to define when, how and by whom the conformity assessment audit shall b
24、e conducted. Such a conformity assessment is expected to contribute to an increased trust by service providers, customers, regulators and other stakeholders that metering and billing processes are reasonably monitored. ETSI ETSI TS 102 846 V1.1.1 (2010-06)51 Scope The present document details the sp
25、ecific requirements an independent party should comply with, in addition to the generic standard ISO/IEC 17065 2 to assess conformity of the checking-up on metering and billing processes with the requirements defined in TS 102 845 1. 2 References References are either specific (identified by date of

38、ns that the entity in charge of checking has some level of independence from the entity in charge of operating metering and billing within the service provider. The externality means that the checking entity does not have to understand all the complexity of the information systems and network compon

44、compliance of the verification process with requirements described in document TS 102 845 1. NOTE: conformity assessment is not concerned with the way a service provider meters and bills its customers, but with the way a service provider verifies that it meters and bills correctly the electronic com
45、munications of its customers. Figure 1 illustrate the different roles and actions of entities involved in the conformity assessment Process. Figure 1: Role of Entities and Applicable Standards in Conformity Assessment of Metering and Billing 4.2 Types of conformity assessment It is expected that som
46、e service providers may outsource the metering and billing checking to an external third party and that other service providers may insource the checking-up on metering and billing. In order to address these two schemes, two types of conformity assessment have been defined: A) External BVB (Billing
47、Verification Body). When an external BVB checks-up on metering and billing of several service providers, the conformity assessment of the BVB can be carried on the basis of methods used by the BVB and examples of service providers monitored by the BVB. This is called a type A conformity assessment.
48、B) Internal BVB. When a service provider executes with its own means the checking-up on its own metering and billing processes, the conformity assessment is carried out on the basis of the process used to check metering and billing. This is called a type B conformity assessment. With this flexible s
49、cheme, when a service provider wants to make stakeholders confident that the quality of his billing is checked according to the standard TS 102 845 1, he will have the choice between: subcontracting the metering and billing checking-up process to an external BVB which has an up-to-date generic type A conformity assessment awarded by a CAB (Conformity Assessment Body); or executing by its own means the Metering and Billing Checking process and hiring a CAB to receive and update a specific type B conformity assessment.
