The transition from 3G to 4G LTE (Long Term Evolution) marked a paradigm shift in mobile telecommunications. While 3G networks relied on a hybrid of circuit-switched (voice) and packet-switched (data) architectures, 4G LTE adopted an approach. At the heart of this transformation lies the Evolved Packet Core (EPC) . In this article
