提供新的NGN服务需要新的KPI；QoS测量；以及确保新服务质量所需的基准方法。为了确保测试结果的可比性，需要参考基准测试方法和背景交通负荷曲线。本文件:确定并定义语音和传真电话服务可能的关键性能指标；定义潜在应用范围的基准测试方法。定义的测试程序的范围是评估VoIP和FoIP对移动网络服务的网络访问。测量在移动设备与测量点之间进行，测量点可以是移动设备或模拟核心网络中理想终端的设备。被测运营商提供的所有接入技术都会得到考虑。在这种情况下，通过分析网络上可访问的信号来进行测量和关键性能指标的确定。 本文件不打算与ETSI TS 102 250[i.3]系列的范围重叠。该系列中描述的测量不受本文件规定的影响。本文件包含UMTS和VoLTE的可能KPI，以及参考基准测试的框架要求，尤其是关于背景流量概况。

The offer of new NGN services requires new:KPIs;QoS measurement; andbenchmarking methodswhich 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.
