18、smission and Quality Aspects (STQ). The present document is part 4 of a multi-part deliverable covering Speech Processing, Transmission and Quality Aspects (STQ); User related QoS parameter definitions and measurements, as identified below: Part 1: “General“; Part 2: “Voice telephony, Group 3 fax, m

19、odem data services and SMS“; Part 3: “QoS parameters specific to Public Land Mobile Networks (PLMN)“; Part 4: “Internet access“. EG 202 057-1 i.2 contains general user related QoS parameter definitions and measurement methods that can be applied to any service as well as user related QoS parameter d

20、efinitions and measurement methods for voice, data and fax services accessed via the public telecommunications network. EG 202 057-2 i.3 contains user related QoS parameter definitions and measurement methods for voice, modem data, fax services and SMS accessed via the public telecommunications netw

21、ork. The data parameters are specified for the case where a V.9x series modem is used since this kind of modem is in common use. EG 202 057-3 i.4 contains user related QoS parameter definitions and measurement methods specific to public land mobile telecommunication networks (PLMN). EG 202 057-4 (th

22、e present document) contains user related QoS parameter definitions and measurement methods specific to Internet access. The present document takes into account as far as practicable the following eight principles: 1) QoS parameters should be easily understood by the public, and be useful and import

23、ant to them. 2) All parameters are applicable at the network termination point (where appropriate). 3) Where measurements are possible they should be made on the customers premises, using in-service lines. NOTE: Literally principles 2 and 3 imply that all measurements are carried out at the NTP. How

24、ever, the NTP in PLMNs is not precisely defined. Other methods are used to achieve an adequate representation of the quality that would be perceived at the NTP for the parameters defined in the present document. 4) To be as realistic as possible, real traffic rather than test calls should be used as

25、 a basis of the measurements, wherever possible. 5) Parameters should be capable of verification by independent organizations. This verification might be made by direct measurements or by audit of service providers measurements. 6) The accuracy of QoS values should be set to a level consistent with

26、measurement methods being as simple as possible with costs as low as possible. ETSI ETSI EG 202 057-4 V1.2.1 (2008-07) 6 7) The parameters are designed for both statistical and individual application. The statistical values should be derived by the application of a simple statistical function to the

27、 individual values. The statistical function should be specified in this multi-part deliverable. This multi-part deliverable should also contain guidelines on how statistically significant samples should be selected. 8) The statistical functions should be designed so QoS figures from different servi

28、ce providers can be compared easily by users and in particular consumers. Introduction The present document provides definitions and measurement methods for various QoS parameters for Internet access. The parameters were developed on the basis of the users Quality of Service criteria identified in t

29、he TR 102 276 i.1. ETSI ETSI EG 202 057-4 V1.2.1 (2008-07) 7 1 Scope The present document contains definitions and measurement methods for a range of user perceivable Quality of Service (QoS) parameters. The purpose of these parameters is to define objective and comparable measures of the QoS delive

30、red to users/customers for use by users/customers. The present document applies to any telecommunication service however some parameters may have a limited application. The present document is intended to provide a menu from which individual items can be selected. There is no obligation to use any o

31、r all of the parameters. The QoS parameters are related primarily to services and service features and not to the technology used to provide the services. Therefore the parameters should be capable of use when the services are provided on new technologies such as IP and ATM or other packet switched

32、technologies as well as on circuit switched technologies. The establishment of target values for QoS is outside the scope of the present document. The QoS parameters listed in the present document are also not intended to assess the complete QoS of a telecommunication service. The present document p

33、rovides a set of QoS parameters that covers specific user related QoS aspects rather than a complete list of QoS parameters. This set has been chosen to address areas where monitoring of QoS is likely to be most worthwhile, i.e. the areas that are most likely to be affected by any QoS problems. If s

34、takeholders wish to examine other QoS aspects they are recommended to follow the general approach of the present document - as far as practicable - as a basis for the development of definitions and measurement methods for new specific QoS parameters. The set of QoS parameters is designed to be under

35、stood by the users of various telecommunications services. Sub-sets of these parameters can be selected for use in different circumstances. For example a specific parameter might be relevant for many users in some countries or markets but the same parameter might not be of relevance in others. There

36、fore stakeholders - users, customers, regulators, service providers, network operators and other parties interested in the use of QoS parameters - should decide in co-operation, which parameters should be used in their particular situation. This decision should take account of: The precise purpose f

37、or which they will be used. The general level of quality achieved by most operators. The degree to which the parameters will provide a reliable comparison of performance. The cost of measuring and reporting each parameter. The parameters defined in the present document are applicable to any kind of

38、Internet access independently of the underlying technology. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
