A method for congestion warning and access control of a satellite cluster public signaling channel

PendingCN122093752AImplement congestion warningImplement access controlNetwork traffic/resource managementNetwork topologiesWireless resource managementTrunking
This invention discloses a method for congestion warning and access control of a satellite trunking common signaling channel. A State Service (STS) server uses statistical information on random satellite access and radio resource management (RRM) allocation from the terminal as a traffic status report, which is broadcast to users in real time via the common signaling channel. The satellite trunking terminal adjusts its access based on the user priority assigned at activation and the current system broadcast, forming a congestion warning and flow control mechanism. Based on the random access RACH information, users can obtain the uplink access traffic on the common channel of their respective beam within a unit of time. Based on the satellite resource management (RRM) information, users can obtain the probability of successfully requesting access beam resources within a unit of time. According to a predetermined access control strategy, the terminal initiates uplink traffic tiered restrictions before beam congestion, ensuring that users with different priorities receive corresponding communication connection rates. This provides users with better tiered satellite trunking access services and effectively prevents systemic traffic paralysis due to channel resource exhaustion.
