6G non-standalone solution based on heterogeneous network aggregation

Abstract

In view of the challenge of unmatched high cost investment and operating income at the initial stage of satellite Internet construction, the 6G non-standalone solution based on air ground integration was studied. A heterogeneous satellite Internet operation mode integrating Overlay and Underlay was proposed. The multi-orbit satellite network was abstracted into a unified resource pool through virtualization technology, and a phased evolution path was designed. In the initial stage, satellite ground cooperative access was achieved by relying on 5G core network. In the mid-stage, sinking user plane functions reduced the delay. In the last stage, satellite ground cooperative control plane was built to achieve global resource scheduling. This solution achieves deep collaboration between satellite networks and ground 5G/6G core networks through phased architecture evolution, verifying the ability of heterogeneous resource virtualization aggregation and real-time business stability guarantee, and providing a feasible technical path for low-cost construction of 6G space-air-ground integrated networks.
