摘要

移动数据服务正在迅速渗透移动市场。随着无线技术和市场的发展,移动通信行业严重依赖数据业务来取代传统的语音业务。一个可靠的分组业务网络是移动运营商在数据业务市场中保持核心竞争力的关键。此外,移动运营商需要开发有效的运营模式,以管理单一网络上各种混合的语音、数据和视频流量。应用统计模型可以证明是一种有效的方法。本文首先介绍了通用移动通信系统(UMTS)分组交换(PS)网络的体系结构,然后对UMTS分组交换网络中各网络实体监控的关键绩效指标(KPI)进行多元统计分析,指导网络的长期容量规划。本文提出的方法有助于移动运营商长期运营和维护其3G分组交换网络。

A performance analysis for UMTS packet switched network based on multivariate KPIs
Mobile data services are penetrating mobile markets rapidly. The mobile industry relies heavily on data service to replace the traditional voice services with the evolution of the wireless technology and market. A reliable packet service network is critical to the mobile operators to maintain their core competence in data service market. Furthermore, mobile operators need to develop effective operational models to manage the varying mix of voice, data and video traffic on a single network. Application of statistical models could prove to be an effective approach. This paper first introduces the architecture of Universal Mobile Telecommunications System (UMTS) packet switched (PS) network and then applies multivariate statistical analysis to Key Performance Indicators (KPI) monitored from network entities in UMTS PS network to guide the long term capacity planning for the network. The approach proposed in this paper could be helpful to mobile operators in operating and maintaining their 3G packet switched networks for the long run.
