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.
