摘要
对EPC网络演进、承载管理、CSFB、VoIP等进行了研究分析,结合运营商部署EPC网络的实际需求,提出了接入类、会话类、移动性、业务量、资源负荷等五类指标,并详细给出每类指标的原始指标统计点及计算方法。通过对这些指标的统计和分析,运营商能够对网络性能进行评估、分析用户行为和发现网络问题。
It analyzes the network evolution, bearer management, circuit services fal back and VoIP of EPC, and raises five categories of key performance indicators, such as accessibility, session management, mobility, traffic volume, and resource/load, according to the operators’deployment policy of EPC. For each of al five categories of KIPs, the KPI calculation methods and the primary timers statistical methods are given. With these KPIs, the operator can evaluate the network performance, analyzes the user model, and discover network problems.
