AI Technical Summary
The existing random access mechanism of satellite networks cannot effectively guarantee low-latency and high-reliability transmission of time-sensitive services. The rigid resource allocation strategy leads to inefficiency, and the congestion control mechanism is lagging and has high signaling overhead.
A credit mechanism and a dynamic preemption mechanism are introduced. Through signaling structure design and frame structure adjustment, the terminal maintains a credit counter, the satellite dynamically adjusts the competition and protection areas, and the terminal selects the access method according to the credit value and service type.
It implements a dual-protection path for time-sensitive services, improves resource utilization, reduces signaling overhead, has good compatibility, is easy to deploy, and reconciles the contradiction between service protection and system efficiency.
