18、 VoLTE“; Part 4: “Reference benchmarking for IPTV, Web TV and RCS-e Video Share“. Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Draft

Introduction The present document describes the reference benchmarking, background traffic profiles and key performance Indicators for UMTS and V
20、oLTE. ETSI ETSI TS 103 222-3 V1.1.1 (2015-12)5 1 Scope The offer of new NGN services requires new: KPIs; QoS measurement; and benchmarking methods which are needed to ensure the quality of new services. To ensure the comparability of test results, reference benchmarking methods and background traffi
21、c load profiles are needed. The present document: identifies and defines possible key performance indicators for voice and fax telephony services; defines benchmarking methods for the spectrum of potential applications. The scope of the defined testing procedures is the evaluation of the network acc
22、ess by VoIP and FoIP for mobile -network services. The measurements are conducted between a mobile device to a measurement point which can be a mobile device or a device emulating an idealized termination point in the core network. All access technologies offered by the operator under test are consi
23、dered. In this context the measurements and key performance indicators determinations are performed by analysing signals accessible on the network. The present document is not intended to overlap with the scope of the series ETSI TS 102 250 i.3. Measurements described in that series are not affected
24、 by the provisions of the present document. The present document contains possible KPIs for UMTS and VoLTE as well as framework requirements for reference benchmarking particularly with regard to background traffic profiles. 2 References 2.1 Normative references References are either specific (ident

40、nts including but not limited to the following: analogue (a/b), ISDN, VoIP (including SIP trunking), high-speed internet, UMTS and VoLTE. The performance data which are collected will be relevant for a real-world environment encompassing a mix of technologies. This approach ensures that service qual
41、ity is evaluated from a customers point of view, since all system components involved in an end-to-end connection are incorporated into the test. 4.2 Scope of functionality A benchmarking platform can be distributed across a larger region or an entire country. In this case several server systems sho
42、uld be also part of the setup, including: a business intelligence platform; a data warehouse, a management system and a system for evaluating of media (e.g. video, audio and voice) quality. The measurement systems at the user premises are connected electrically to VoLTE and UMTS. The test system (Qo
43、S control and data server) is connected through UMTS, LTE or ISDN connections (via IMS PES with AGCF (or PSTN or ISDN Access) or IMS PES with VGW) or MMTel (IMS) fixed access lines for voice quality measurements.
