A study on interconnection between local 5G networks and existing networks

Abstract

This paper reports a method for interconnecting local 5G networks and existing networks. Since the two networks are often separated, there is a demand to interconnect the two networks. However, operation gaps such as addressing policy and security policy between the two networks will not allow one to interconnect. To fill the gaps, an interconnection method consists of inter-layer address translation and tunneling in existing networks is proposed and implemented. The evaluation result using an actual local 5G network and an actual corporate intranet revealed that the proposed method works properly.
