Signaling Priority Reconstruction for Micro-serviced AMF in 6G

As the concept of the sixth-generation mobile communication technology (6G) continues to mature, Low Earth Orbit (LEO) satellite technology, serving as a crucial component of the high-coverage, fully accessible network in 6G, holds promising development prospects. Consequently, the integration of next-generation mobile communication technology with LEO satellite networks has garnered increased attention in the industry. However, despite some research groundwork in the direction of integrating LEO satellite networks with 5G networks, many challenges persist, especially concerning the issue of signaling storms arising from collective handovers and registrations in the face of a large user base. This paper proposes a process-level prioritized architecture design for the Access and Mobility Management Function (AMF), capable of expediting the processing of critical procedures amid a plethora of mixed signals. Preliminary experimental verification is conducted using a newly developed open-source testbed based on UERANSIM. The presented results demonstrate that the proposed AMF mechanism effectively reduces the latency of completing specified procedures in scenarios involving a substantial volume of mixed signals.
