Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] A method for allocating satellite communication channel resources, based on a satellite and an earth station communicating with the satellite, comprising:

[0043] Step S102: Obtain required channel resources of the communication link between the satellite and the earth station.

[0044] Obtain the required channel resources of the communication link between the satellite and the earth station, where the required channel resources can also be understood as occupied bandwidth. The required channel resource can be obtained through a preset algorithm, or obtained through a resource allocation ...

Abstract

The invention relates to a satellite communication channel resource allocation method. The allocation method includes the steps of acquiring required channel resources of a communication link between a satellite and an earth station; acquiring maximum communicable channel resources of the communication link, the maximum communicable channel resources being channel resources when the signal strength received by the earth station is a demodulation threshold; acquiring idle channel resources of the communication link; and when the required channel resources are less than or equal to the maximum communicable communication channel resources, allocating the required channel resources from the idle channel resources to the communication link. By synthetically analyzing a size relationship among the maximum communicable channel resources, idle channel resources and the required channel resources of the current communication link and selecting an appropriate allocation strategy to allocate the resources, the allocation method can ensure the effectiveness of the channel resource allocation, avoid the problem of successful channel resource allocation but communication failure, and improve the efficiency of resource allocation and system reliability and practicability.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a method for allocating satellite communication channel resources. Background technique [0002] Satellite communication refers to the communication between radio communication stations on the earth (including the ground and the lower atmosphere) using satellites as relays. The satellite communication system consists of two parts: satellites and earth stations. Satellite communication has the advantages of large communication range, high reliability, rapid circuit opening, multiple address communication, and multiple address connection. The communication capability of the satellite link is related to the carrier parameters of the earth station (such as modulation mode, coding mode, demodulation threshold, etc.), antenna parameters (antenna aperture, up-conversion amplifier power, etc.), satellite transponder parameters (effective omnidirectional transponder Radi...
