A cellular network consists of a radio network, one or more core networks, and a services network. The LTE Evolved Packet Core (EPC) is the next-generation
core network that is expected to replace the existing/legacy core networks. A typical 3G core network consists of a Circuit Switched Core Network (CS-CN) and
a Packet Switched Core Network (PS-CN). The EPC is an all-IP packet-switched core network that can connect to a variety of radio networks such as the LTEbased
E-UTRAN, WCDMA-based UTRAN, GERAN, CDMA2000 1x, 1xEV-DO/HRPD, and WiMAX. The EPC is formally defined by 3GPP as part of the Evolved
Packet System (EPS) that uses an LTE-based EUTRAN. This eLearning course provides an overview of the EPC, including the architecture, basic functions, its
role in session setup, and its support for inter-technology mobility.

This course is intended for those seeking a fundamental understanding of how EPC works in the next-generation cellular network. This includes those in a design, test, systems engineering, sales engineering, network engineering, or verification role.

After completing this course, the student will be able to:
• Summarize key benefits and challenges of the EPC
• Specify roles of various EPC components
• Explain the functions (e.g., authentication and security) performed
by the EPC
• Describe a high-level session setup using the EPC
• Discuss how EPC supports inter-technology handover
