A Beidou short message communication method for a satellite remote education system

Abstract

The invention particularly discloses a Beidou short message communication method for a satellite remote education system, which comprises the following steps of: 1, a subscription message is packagedinto a data packet through a satellite network receiving server, and the data packet is sent to a BD gateway through a Beidou satellite short message interface; 2, the BD gateway carries out data packet analysis on the received data packets respectively; Step 3, the BD gateway sends a feedback packet to a satellite network receiving server through a Beidou satellite short message interface according to a data packet analysis result; and 4, the satellite network receiving server carries out feedback packet analysis on the received feedback packet, and sends a confirmation completion or resending data packet according to a feedback packet analysis result. The interactive information service can be provided for an existing one-way push satellite remote education system, a terminal user can customize the teaching content according to needs, and remote education can also be conducted in remote areas through an interactive method.

Description

technical field [0001] The invention relates to the communication field, in particular to a Beidou short message communication method oriented to a satellite distance education system. Background technique [0002] At present, there is still a certain gap between the informatization construction in remote areas compared with cities with fiber optic access and other network coverage such as 4G, and further vigorous support and development are needed. Taking remote areas such as farming and pastoral areas in the Inner Mongolia Autonomous Region as an example, there is no basic network facilities such as optical fiber, so traditional broadband networks cannot be used to obtain network resources; although mobile communication networks have achieved coverage in remote areas, remote areas cannot access mobile The network can only use 2G services with a low communication rate, and it is difficult to access relatively fast mobile communication networks such as 4G to obtain network r...

Problems solved by technology

Taking remote areas such as farming and pastoral areas in the Inner Mongolia Autonomous Region as an example, there is no basic network facilities such as optical fiber, so traditional broadband networks cannot be used to obtain network resources; although mobile communication networks have achieved coverage in remote areas, remote areas cannot access mobile The network may only use 2G services with a low communication rate, and it is difficult to access relatively fast mobile communication networks such as 4G to obtain network resources

Satellite distance education is an important form of modern distance education. It has the advantages of wide coverage and low cost, but its disadvantage is that it is difficult for end users to subscribe to teaching content according to their own needs.
