8、1000/11830-en. ii Rec. ITU-T M.3710 (11/2013) FOREWORD The International 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 permane
9、nt 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 Telecommunication Standardization Assembly (WTSA), which meets every four years, establishe
10、s 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 information technology which fall within ITU-Ts purview, the necessary standard
11、s 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 agency. Compliance with this Recommendation is voluntary. However, the Recomme
12、ndation 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 other obligatory language such as “must“ and the negative equivalents are
13、 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 implementation of this Recommendation may involve the use of a claimed Inte
14、llectual Property Right. 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 process. As of the date of approval of this Recommendation, ITU had not recei
15、ved notice of intellectual property, protected by patents, which 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

A network operator may
27、be a service provider and vice versa. A network operator may or may not provide particular telecommunications services. 3.1.2 quality of service (QoS) ITU-T E.800: Totality of characteristics of a telecommunications service that bear on its ability to satisfy stated and implied needs of the user of
28、the service. 2 Rec. ITU-T M.3710 (11/2013) 3.1.3 service ITU-T M.3050.1: Services are developed by a service provider for sale within products.

34、 QoS Quality of Service SLA Service Level Agreements SP Service Provider 5 Conventions The following conventions are used in this Recommendation: The keywords “is required to“ indicate a requirement which must be strictly followed and from which no deviation is permitted, if conformance to this Reco
35、mmendation is to be claimed. Rec. ITU-T M.3710 (11/2013) 3 The keywords “is prohibited from“ indicate a requirement which must be strictly followed and from which no deviation is permitted, if conformance to this Recommendation is to be claimed. The keywords “is recommended“ indicate a requirement w
36、hich is recommended but which is not absolutely required. Thus, this requirement need not be present to claim conformance. The keywords “is not recommended“ indicate a requirement which is not recommended but which is not specifically prohibited. Thus, conformance with this Recommendation can still
37、be claimed even if this requirement is present. The keywords “can optionally“ indicate an optional requirement which is permissible, without implying any sense of being recommended. This term is not intended to imply that the vendors implementation must provide the option and the feature can be opti
38、onally enabled by the network operator/service provider. Rather, it means the vendor may optionally provide the feature and still claim conformance with this Recommendation. 6 Concepts and background 6.1 Overview Providing high quality telecom services to end users in a cost-efficient manner is the
39、key for a NO/SP aiming to gain a sustainable competitive advantage. The NO/SP needs to ensure that services delivered to customers are continuously available and meet the requirements of SLA or QoS levels. At the same time, reducing the operating costs and increasing operation efficiency is another
40、important consideration for telecom operators. The automated service test is a solution for end-to-end service quality assurance that uses an automated test facility which can proactively search for network failure and/or service quality deterioration. Appendix I describes some examples of automated
41、 service test scenarios. The automated service test is able to ensure the quality of a wide range of telecom services such as voice services, messaging services, data services, value-added services, etc. Appendix II describes some use-cases of the automated service test. 6.2 Position in the eTOM bus
42、iness process framework Figure 1 illustrates the position of the automated service test in the eTOM business process framework ITU-T M.3050.1. The automated service test is an element of the assurance operations process, which supports service problem management and service quality management of the
43、 service management and operations function. 4 Rec.

The automated service test is controlled by test programmes defined by the test manager. Test points receive test requests from the test programme and invoke test scripts to perform service test operations. M.3710(13)_F03Test pointTest pointTest scriptTest pointTest managerTest
