摘要:

非结构化补充业务数据(USSD)是ETSI定义的一种基于全球移动通信系统(GSM)网络的新型交互式数据业务。为了给USSD业务平台提供一个性能评价手段,本文使用排队网络方法建立了USSD业务平台的性能模型,并使用近似平均值分析(MVA)算法对该业务平台上开展的USSD预付费充值业务进行了分析。对性能指标的分析表明,可以通过该性能模型找到制约系统性能的瓶颈。在OPNET上的仿真实验验证了分析的有效性。

Abstract:

USSD(unstructured supplementary service data) is a new data service defined by ETSI for use within the GSM. Aiming at providing evaluation means for the service performance of USSD service platform, this paper presents the performance model based on Queueing Network. With the analysis of the Pre-Paid Replenish service deployed on the USSD service platform, we have obtained some performance metrics through using the approximate Mean Value Analysis algorithm. These metrics help to find the bottleneck of the system and improve the quality of service. Finally, OPNET is used to simulate the system, and verified the accuracy of this model.
