The existing 4G and 5G devices can generally support the dual-stack IP address networking carried by 5G base stations, but there are still difficulties in how to span a variety of professional networks and accurately complete the end-to-end networking configuration in the current network. To solve this problem, aiming at large-scale engineering deployment, an end-to-end dual-stack networking scheme for 5G base station is proposed, and the sliced packet network(SPN) system and the existing network end-to-end are tested and verified in the real network environment. The test results are given to verify the feasibility of the dual stack networking scheme. Finally, an example is given to introduce the troubleshooting method.
