Udemy – 4G LTE EPC: Architecture, Protocols, and Call Flows

Whether you are a telecom professional, network engineer, or a student aiming to build a solid foundation in mobile networks, this course is designed to take you from the basics to advanced concepts of the Long Term Evolution (LTE) network. This course provides an in-depth dive into the LTE Architecture, Protocol Stacks, Node Configurations, and Call Flows. You will gain practical knowledge of the Evolved Packet Core (EPC) in LTE, understanding how they interact to deliver high-speed mobile broadband.

What you will learn:

• Complete LTE Architecture: Understand the end-to-end architecture, including the E-UTRAN (eNodeB) and the EPC (MME, SGW, PGW, PCRF, HSS, DRA, ePDG, AAA Server).
• CUPS and Roaming Architectures: Explore Control and User Plane Separation (CUPS) and delve into Roaming Architectures like Local Breakout (LBO) and S8 Home Routed (S8HR).
• In-Depth Protocol Stack Analysis: Master critical LTE protocols and interfaces, including S1AP, GTP-C, GTP-U, PFCP, and Diameter. We will cover the protocol stacks for eNodeB, S1-MME, S1-U, S11, S5-S8, and Gx interfaces.
• Practical Node Configurations: Get hands-on insights into sample configurations for key LTE nodes: MME, SGW, PGW, PCRF, and ePDG.
• LTE Node Selection Procedures: Learn the procedures behind the selection of MME, SGW, PGW, PCRF, and SRVCC targets.
