Cloud5GC : Design and implementation of scalable and stateless mobile core system on public cloud

For contemporary IT services, Wireless communication, facilitated by mobile phones, is a fundamental infrastructure. 5G comprises RAN (Radio Access Network) and Mobile Core (5GC) technologies. Specifically, 5GC handles communication from smartphones and IoT devices, enabling communication tailored to each use case, thereby solidifying its position as the Mobile Core system within the 5G network. With the recent proliferation of smartphones and IoT devices, along with advancements such as digital twins, there has been a substantial increase in traffic demand on 5GC. This surge has compelled telecom companies to invest heavily in equipment upgrades and operational maintenance to ensure stable 5GC communication. To address the challenges in the Mobile Core, our research has aimed at reimagining the 5GC architecture. We introduced Cloud5GC, a groundbreaking solution that transitions away from traditional function-based systematization towards a more cohesive micro Mobile core architecture. Implementing Cloud5GC on a public cloud platform demonstrated its flexibility, resilience, and fault-tolerance. Our findings underscore the architectural excellence of Cloud5GC, representing a significant advancement in 5G communications.
