NGN中语音业务质量监测参数的研究

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。

Analysis on Monitoring Parameters of Voice-Service QoS in NGN

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.
