Satellite communication system outbound resource optimization management method

Abstract

The invention discloses a satellite communication system outbound resource optimization management method, which comprises data priority management and outbound link resource scheduling, and the data priority management comprises establishment of priority queues, distribution of weights of the priority queues and judgment of user data priorities. The outbound link resource scheduling comprises priority queue data extraction, link selection, data framing processing and frame data storage. According to the method, a resource allocation strategy of an outbound link can be adjusted according to the priority of the user data and the dynamic change of the resource state of the outbound link, so that high-performance operation of the system is ensured, the utilization rate of the system is increased to the greatest extent, and high-quality communication service is provided under the trend of rapid increase of industry requirements and the number of users. The method is of great significance in how to balance satellite link resources and service request priorities under the condition of a large amount of user data and providing higher-quality and faster services for users in a short time as much as possible.

Description

technical field [0001] The invention relates to the field of satellite communication algorithms, in particular to a method for optimizing and managing outbound resources of a satellite communication system. Background technique [0002] The satellite communication system refers to sending and receiving signals by the ground central station, using satellites as relays, so as to achieve communication between the central station and the central station, between the handheld terminal and the handheld terminal, and between the central station and the handheld terminal. Its main purpose is to achieve "seamless" coverage of the ground. It is currently widely used in many fields such as navigation, sea and air, port traffic detection, hydrological monitoring, disaster rescue, and forecasting. With the gradual reduction of the cost of satellite communication, the increasing demand for satellite communication in various industries, and the arrival of the 5G era, the concept of satelli...

Problems solved by technology

Although this scheduling algorithm is simple and easy to implement, it does not consider the impact of other factors on the overall performance of the system, including link status, service type, user type, system delay requirements, etc.

When a large number of users are concurrent, it will cause the problem of uneven allocation of system resources. In severe cases, it may also cause link data squeeze and outbound queuing congestion, so that low-priority data cannot be outbound in time according to the specified response time.
