ETSI TS 186 008-2描述了基于IMS的服务MMTel、Video的性能基准方法 电话和IMS/PES。TR 101 577[i.11]中描述了术语和概念。本文件是 多部分交付成果的第二部分，由四部分组成。TS 186 008-1[i.1]定义了总体基准描述、体系结构、流程和信息模型，这些都是 所有特定基准测试场景都通用。本文件包含具体的基准测试用途- 案例和场景，以及特定场景 指标和设计目标。它还定义了SUT配置参数。本文件还载有 对本文件总体描述的任何必要扩展，如有必要，用于特定用途 脚本TS 186 008-3[i.2]通过对流量集、流量时间剖面和流量的规范定义了初始基准测试 基准测试程序。TS 186008-4[i.3]定义了TS 186008中定义的用例的参考负荷网络质量参数- 2[i.1]。

ETSI TS 186 008-2 describes the performance benchmark methology for the IMS based services MMTel, Video Telephony and IMS/ PES. The terminology and concepts are described in TR 101 577 [i.11]. The present document is the second part of the multi-part deliverable which consists of four parts.TS 186 008-1 [i.1] defines the overall benchmark descriptions, architectures, processes, and information models that are common to all specific benchmarking scenarios.The present document contains the specific benchmarking use-cases and scenarios, along with scenario specific metrics and design objectives. It also defines the SUT configuration parameters. The present document also contains any required extensions to the overall descriptions present in the present document, if necessary for the specific scenario.TS 186 008-3 [i.2] defines an initial benchmark test through the specification of a traffic set, traffic-time profile and benchmark test procedure.TS 186 008-4 [i.3] defines Reference Load network quality parameters for the use cases defined in TS 186 008-2 [i.1].
