EPC Signalling & IMS Overview training by TelcoLearn
- 1. EPC SIGNALLING & IMS OVERVIEW www.Telcolearn.com
- 2. Learning Outcomes • Comprehensive Understanding of LTE EPC Architecture: Students will gain a solid understanding of the LTE Evolved Packet Core (EPC) architecture, including its key nodes, functions, interfaces, and protocols used for managing data and signaling in 4G networks. • In-Depth Knowledge of EPC Procedures and Signaling: Students will learn how EPC handles critical procedures like attach/detach, service requests, mobility management (handover, tracking area updates), and bearer activation, along with the ability to analyze EPC logs. • Expertise in Security and QoS Management in LTE Networks: Students will be equipped with knowledge about the security mechanisms in EPC, including authentication and key management, as well as the Quality of Service (QoS) framework, policy control, and enforcement (PCRF & PCEF). www.Telcolearn.com
- 3. Learning Outcomes • Hands-On Knowledge of Mobility Management and Network Evolution: Students will understand how mobility is managed in LTE (including handovers, tracking area updates, and interworking with 3GPP networks), as well as how EPC is evolving with virtualized EPC (vEPC) and CUPS (Control and User Plane Separation). • Proficiency in IMS and VoLTE Services: Students will learn about the evolution of IMS, its services (e.g., VoLTE, multimedia messaging), its architecture, and related protocols (SIP, RTP, QoS) for effective voice and multimedia communications, including the transition towards VoNR in 5G. www.Telcolearn.com 2/2
