The invention discloses a satellite air interface message caching and speed-limiting processing method and device, equipment and a medium. The method comprises the following steps: acquiring and receiving a broadband message at a first rate sent by a high-speed channel; respectively performing parallel caching on the received broadband messages at the first rate in a preset parallel space according to different user identifiers; limiting the speed of the message data subjected to parallel caching to be a message at a second rate according to a first-in first-out principle, and sending the message through a satellite signal; wherein the second rate is less than the first rate. The invention provides a method for caching, forwarding and limiting the speed of the downlink message of the satellite terminal based on the GGSN equipment, the message of a satellite air interface is cached and limited according to a preset rule, the congestion rate is reduced, the channel efficiency is improved, and the packet loss rate is greatly reduced; the method is simple and convenient to operate, easy to implement and low in implementation cost, and convenience is provided for use of a user.
Description
technical field [0001] The invention relates to the technical field of satellite communication, in particular to a satellite air interface message buffering and speed limit processing method, device, computer equipment and storage medium. Background technique [0002] Satellite broadband communication, also known as multimedia satellite communication, refers to the processing and transmission of voice, data, images and video through satellites. Because the bandwidth of the satellite communication system is much smaller than that of the optical fiber line, tens of megabits per second is called broadband communication. Providing greater bandwidth is only part of the satellite communication program, and satellite-based communication also provides opportunities for many new applications and new services. Because satellite resources are very expensive, the bandwidth available to each user is within 40KB / s. Compared with the existing optical fiber, WIFI and other hundreds of M pe...
