Research on lightweight core network solutions for 5G private networks

Unlike traditional 5G public network services, 5G vertical industry applications have highly customized requirements in terms of coverage, latency, reliability and transmission bandwidth, which differ greatly from traditional public 5G networks, making it difficult to adopt a unified 5G public network architecture and performance requirements. Light-weight 5G Core network can provide a good solution. This paper proposes a lightweight 5G private network architecture design scheme, incorporating Mobile Edge Computing(MEC) architecture on a user side to achieve flexible and mobile rapid deployment of 5G private networks, and proposes a lightweight access authentication process applicable to 5G private networks, reducing redundant processes and improving the overall performance of the system. Through experimental verification, it can effectively reduce the access delay and end-to-end transmission delay of terminals.
