Design and Implementation of a Redundant Transmission Technique for Ultra-Reliable Communication in 5G Core Networks

In order to provide an industry-grade 5G Private Network (PN) to the enterprises, the ultra-reliability communication becomes a key feature to successfully deploy 5G PNs for the future industry 4.0 applications. This paper article will use the free5GC, which is the world's first open-source 5G core (5GC) network that complies with 3rd Generation Partnership Project (3GPP) R15 standards, developed in the laboratory as the base to develop a redundant transmission technique for Ultra-Reliable Communication in 5G Core Networks. We compare the its performance and reliability with the original a single protocol data unit (PDU) session in free5GC. Moreover, it confirmed that the reliability it brings would enable users to have a better user experience.
