4G and 5G Core Networks: Design and Evolution
This Learning Path explores the evolution of core networks from 4G LTE to 5G, starting with the architecture and components of the Evolved Packet Core (EPC) in 4G, including MME, SGW, PGW, and HSS. It then transitions to the 5G Core (5GC), introducing concepts such as Service-Based Architecture (SBA), AMF, SMF, UPF, and NRF. Through hands-on labs, you'll gain practical experience in configuring and analyzing both 4G and 5G core networks, understanding their functionalities, and exploring advanced features like network slicing and interworking between generations.
