Abstract

The invention discloses a data transmission control method and device based on a synchronous orbit satellite communication system. The method comprises the following steps: acquiring a data transmission request sent by a user terminal; determining a geographic position corresponding to the data transmission request and a destination data type of to-be-transmitted data; determining target climate data matched with the geographic position; converting the target climate data into target climate parameters; converting the target data type into a target QoS parameter; and determining a target radio link control RLC data transmission algorithm for a user terminal according to a plurality of predefined radio link control RLC data transmission algorithms, the target climate parameters and the target quality of service (QoS) parameter. According to the invention, signal attenuation caused by different climates is avoided, the problem of data transmission delay increase caused by climatic environments is solved, and the purposes of reducing the retransmission times of an RLC layer, improving the data transmission success rate and improving the data transmission experience of a user on synchronous orbit satellite communication writing are achieved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data transmission control method and device based on a geostationary orbit satellite communication system. Background technique [0002] The geostationary satellite communication system is a satellite communication system that uses satellites in geosynchronous orbit for communication. At present, the geostationary orbit satellite mobile communication system independently developed and constructed by my country is Tiantong No. 1 satellite mobile communication system, which consists of space segment, ground segment and user terminal. Among them, the space segment is composed of multiple geosynchronous orbit mobile communication satellites; the ground segment is composed of the control center and the ground station; the user segment is the mobile user terminal, which can be handheld, vehicle-mounted, airborne, ship-borne and other mobile terminals. It takes 24...
