The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modi

33、fy the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version 3.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 Indicates TSG approved do

34、cument under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the specification; Introduction The Quality of Experience (QoE),

35、 End-to-end Service Quality of Service (ESQoS) and System Quality of Service (SQoS) are important factors when introducing services to customers. When the next releases of 3G are launched to the mass market, several new mobile telecommunication multimedia services will be introduced to the general p

36、ublic. It is essential that a high quality if service is experienced by the user of these new 3G services in order to promote the idea of 3G as a global all-purpose communication tool for millions of people with widespread availability of terminal equipment. The possibility of using multimedia servi

37、ces via 3G in a practical and reliable manner is extremely important in the near future. For these new services, it is certain that a much larger amount of traffic is generated between mobile terminals and services, i.e. traffic within 3G networks and between 3G networks and other networks will be h

38、igher than has been the case to date. This gives more importance to service quality requirements. End-to-end multimedia service performance metrics are proposed to make it possible for operators, device provider and service providers to more conveniently evaluate their service quality as perceived b

39、y end-users. This includes: Definition of the performance characteristics that have most relevance to end users (the Quality of Experience or QoE). Definition of the mapping between QoE and end-to-end service measured characteristics (the ESQoS), and mapping between ESQoS and service specific charac

40、teristics (the SQoS). In the present document a top-down approach is used to illustrate the framework of all metrics. The present document gives metrics of the end-to-end multimedia service performance on 3G networks that support PSS, PSC, video telephony, MBMS and IMS services, etc. QoE parameters

41、describe the end-to-end quality as experienced by the end users. These are difficult to measure and quantify. SQoS parameters are metrics that are close related to the network status, and defined from the viewpoint of the service provider rather than the service user. SQoS parameters can be viewed a

42、s the inherent attributes of the networks, which are important in guaranteeing QoE requirements of the users. ESQoS parameters describe the QoS of the end-to-end service. They are obtained directly from the QoE parameters by mapping them into parameters more relevant to operators, service providers

43、and service providers. ETSI ETSI TR 126 944 V13.0.0 (2016-01)83GPP TR 26.944 version 13.0.0 Release 13In Annex A, PSS is taken as an example; several general models looking at different part of network are given. A mapping between QoE, ESQoS and SQoS is given using a mathematical approach, which def

44、ines a dimensioned relationship between user experiences and lower tiers of network performance. ETSI ETSI TR 126 944 V13.0.0 (2016-01)93GPP TR 26.944 version 13.0.0 Release 131 Scope The present document describes and defines performance metrics for popular multimedia services in 3G networks, inclu

45、ding packed-switched streaming service (PSS), multimedia broadcast multicast service (MBMS), video telephony (VT), and IP multimedia subsystem service (IMS). The present document has a top-down approach, which starts with the Quality of Experience (QoE) parameters and metrics, and then provides End-

46、to-end Service QoS (ESQoS) and System Quality of Service (SQoS) parameters and metrics and mapping between these different layers. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
