Example one
Fig. 1 is a flowchart of a method for determining a communication mode of a ground station according to an embodiment of the present invention, where the embodiment is applicable to a case where a communication mode between ground stations is determined, and the method may be executed by a ground station communication mode determining apparatus, which may be implemented by software and/or hardware and is specifically configured in a ground network control center.
Referring to fig. 1, the method for determining a communication mode of a ground station is applied to a client, and specifically includes the following steps:
and S110, receiving a communication request between a source ground station and a target ground station associated with the ground network control center.
The Beidou satellite communication system consists of a communication satellite, a ground network control center and a ground station. A communication satellite may achieve complete coverage of ground stations distributed at different locations. The ground network control center may be a centralized network management controller, and is configured to manage network access management, dynamic communication mode switching, and the like of the ground stations within a corresponding range. The different ground network control centers can communicate with each other by means of satellite communication.
The source ground station associated with the ground network control center may be a ground station within a corresponding range managed by the ground network control center, where the source ground station may be used to indicate a ground station that sends a communication request to the associated ground network control center, that is, a ground station that sends communication data in a communication process between two ground stations. The target ground station may be a ground station that communicates with the source ground station, i.e., a ground station that receives communication data during communication between two ground stations. For example, the target ground station and the source ground station may be associated with the same ground network control center, or may be associated with different ground network control centers, which is not specifically limited in this application.
The communication request may be a request for performing communication connection, which is sent by the source ground station to the ground network control center associated therewith, and may be used to instruct the ground network control center to select a target communication mode for the source ground station. Illustratively, the communication request may include the target ground station, the time slot, and the amount of communication data corresponding to the time slot, etc.
And S120, responding to the communication request, and selecting a target communication mode from candidate communication modes, wherein the candidate communication modes comprise satellite communication and carrier communication.
And after receiving the communication request of the source ground station, the ground network control center associated with the source ground station responds to the communication request, namely, selects a target communication mode for the communication between the source ground station and the target ground station. The candidate communication mode is a mode in which communication between ground stations is possible. Exemplary candidate communication modes may include satellite communication, carrier communication, and the like. The target communication mode is a communication mode selected from the candidate communication modes for the current communication.
Specifically, the ground network control center may select the target communication mode according to the communication parameters in the historical communication records of the source ground station and the target ground station. Illustratively, the communication parameter may be a parameter related to a packet loss rate. Specifically, the greater the packet loss rate is, the worse the reliability of communication is, so that the probability of selecting the corresponding communication mode can be reduced to improve the reliability of communication. The communication parameter may also be, for example, a parameter related to the number of communications.

The candidate communication modes comprise satellite communication and carrier communication, the ground stations can adopt one of the candidate communication modes for communication according to requirements, and the communication modes between the ground stations are enriched. When one candidate communication mode has low reliability, other candidate communication modes with high reliability can be selected as the target communication mode, and the reliability of communication between the ground stations is improved. Meanwhile, the whole process of selecting the target communication mode does not need manual participation, the labor cost is reduced, meanwhile, the target communication mode with high reliability can be effectively selected, and further the reliability of communication is improved. Therefore, by means of the technical scheme, the problem that data transmission reliability through satellite communication between the ground stations is low is solved, and the effect of improving the communication reliability between the ground stations is achieved.
