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 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 access 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 considered. 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 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.
