摘要
为了及时管控下一代网络(NGN)中语音业务的服务质量,需要对NGN中的语音业务进行监测,然而,目前业界缺乏对该监测指标的明确定义。在分析了NGN中语音业务质量监测需求的基础上,从会话控制性能、话音质量、编码统计三个方面定义和描述了一套NGN中语音业务质量的监测指标,即NGN语音业务质量检测参数。对这些参数进行有效监测,将及时反映NGN中的语音业务质量和语音业务运营情况,为保证语音业务质量提供有力数据和参考。
In order to control the QoS situation of voice services in NGN,it is necessary to monitor the voice services in NGN.However,till now,no exact defination for monitoring indexes of NGN voice-service QoS exists in the industry.This paper,based on the demand in monitoring voice-service QoS in NGN,and from three aspects incluling performancd of session control,the quality of voice,the statistics of audio code,defines a set of indexes for monitoring Voice-Service QoS in NGN,also called monitoring parameters for Voice-Services QoS in NGN.The monitoring of these parameters would timely reflect,the Qos of voice service and the performance of network,and provide useful information and data for the ensurance of voice-service QoS guarantee.
