Overall, the proposed EPON-based RAN architecture introduces several significant advantages versus that of a typical LTE/5G RAN such as it significantly reduces the signaling overhead and handoff latency, offloading a sizable fraction of the local mobile sessions switch/set-up and tear-down and associated lengthy and complex signaling processing from the overloaded EPC to the RAN¡¯s access nodes. Finally, Re-registration procedures to the Core when the UE moves from a gNB to another is avoided as long as the UE roams within the coverage area served by the gNBs attached to the ring
