Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Such as Figure 1-5 As shown, an economical data transmission method based on satellite broadband short data fusion includes the following steps: receiving a short message generated by an application and corresponding file data; generating a full amount according to the short message and its corresponding file data data; determine whether the broadband network is available; if the broadband network is available, then send the full amount of data to the user terminal through the broadband network; if the broadband network is not available, then send the short message to the user terminal through the narrowband network, and After judging that the broadband network is available again, the full amount of data is sent to the user terminal through the broadband network.

[0036] Wherein, the generated short message and its corresponding file...

Abstract

The invention provides an economical data transmission method based on satellite broadband short data fusion, and the method comprises the steps: carrying out the redundant communication of important application data in the communication of a broadband mobile communication satellite through the short data capability of a narrowband mobile communication satellite; and when the satellite broadband is unavailable, important alarm data is transmitted in a short data transmission manner, so that the problems that the cost of an existing double-satellite data link is too high, and a single-broadband link is influenced by severe weather and is difficult to guarantee the return of important data are solved. The timeliness of data transmission content is ensured, the purposes of reasonably utilizing network resources and saving traffic bandwidth cost are achieved, the user experience perception is improved, and the overall service quality of satellite services is improved.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to an economical data transmission method based on fusion of satellite broadband short data. Background technique [0002] With the vigorous development of my country's satellite communication industry, the scale of construction is expanding day by day, and the coverage of satellite communication is getting wider and wider, including airspace, sea area, and complex areas that cannot be covered by ground networks. The satellite-based communication scheme uses the satellite communication system to provide users with Internet access services through the establishment of communication links between satellites and satellite master stations in dedicated satellite antennas and satellite terminals. Satellite broadband communication refers to the processing and transmission of voice, data, images and video through satellites. Therefore, a series of satellite broadband commun...
