Speech and multimedia Transmission Quality (STQ); Reference benchmarking@ background traffic profiles and KPIs; Part 1: Reference benchmarking@ background traffic profiles and KPIs for VoIP and FoIP in fixed networks (V1.3.1)
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 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 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 subscriber 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 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.
