These systems, typically comprised of terminal devices, base stations, core networks, and management platforms, lack dynamic adaptability and are unable to effectively handle traffic fluctuations caused by massive terminal access. Furthermore, existing technologies are prone to increased access latency and low resource utilization in high-concurrency scenarios, primarily due to fixed resource allocation and a lack of intelligent scheduling mechanisms. Summary of the Invention
