23、 Transmission Quality (STQ). The present document is part 1 of a multi-part deliverable covering the Reference benchmarking, background traffic profiles and KPIs as identified below: Part 1: “Reference benchmarking, background traffic profiles and KPIs for VoIP and FoIP in fixed networks“; Part 2: “
24、Reference benchmarking and KPIs for High speed internet“; Part 3: “Reference benchmarking, background traffic profiles and KPIs for UMTS and 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“
25、, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Intro
26、duction The present document describes possible key performance indicators for VoIP and FoIP as well as framework requirements for reference benchmarking particularly with regard to background traffic. ETSI ETSI TS 103 222-1 V1.1.1 (2015-11)6 1 Scope The present document: identifies and defines poss
27、ible key performance indicators for voice and fax telephony services; defines benchmarking methods for the spectrum of potential applications. 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 t
28、he comparability of test results, reference benchmarking methods and background traffic load profiles are needed. The scope of the defined testing procedures is the evaluation of the network access by VoIP and FoIP fixed-network services. The measurements are conducted stationary between a subscribe
29、r access-point to a measurement point emulating an idealized termination point in the core network. All access technologies offered by the operator under test are considered. In this context the measurements and key performance indicators determinations are performed by analysing signals accessible
30、on the network. The present document is the first part of the multi-part deliverable which consists of four parts. The present document contains possible KPIs for VoIP and FoIP as well as framework requirements for reference benchmarking particularly with regard to background traffic profiles. 2 Ref
