Embodiment 1

[0039] The following provides an example of sending a 250Byte data packet from the management system to the Beidou terminal, as follows:

[0040] Step 101, the communication management system receives the data sent by the third-party management platform, first divides the 250Byte data packet into 3 data packets, and sends each data packet to the host in turn, and the host forwards it to the first master node Beidou terminal (master node 0), and perform fast propagation according to the data transmission mechanism, such as figure 1 shown;

[0041] Step 102, after the set waiting time for the ACK response packet arrives, the communication management system analyzes the received ACK response packet, and when it is judged that the nth Beidou terminal device (slave node nm) on the nth link has no Report the ACK response packet, then the link will not receive the data packet sent by the host from the nm+1th Beidou terminal onwards;

[0042] Step 103, the communication management s...

Embodiment 2

[0047] The following provides another example of sending a 250Byte data packet from the communication management system to the Beidou terminal, as follows:

[0048] Step 201, the communication management system receives the data sent by the third-party management platform, first divides the 250Byte data packet into 3 data packets, and sends each data packet to the host in turn, and the host forwards it to the first master node Beidou terminal (master node 0), and perform fast propagation according to the data transmission mechanism, such as figure 1 shown;

[0049]Step 202, after the set waiting time for the ACK response packet arrives, the communication management system analyzes the received ACK response packet, and when it is judged that the nth Beidou terminal device (slave node nm) on the nth link has no If the ACK response packet is reported, the link from the nm+1 Beidou terminal will not receive the data packet sent by the host; in addition, the r-th Beidou terminal d...

Embodiment 3

[0056] The following provides an example of sending a 250Byte data packet from the Beidou terminal to the communication management system, as follows:

[0057] Step 301, the Beidou terminal (master node or slave node) receives the data sent by the connected third-party terminal, first divides the data packet into 3 data packets, and sends each data packet to the host in turn, and the host forwards it to communication management system;

[0058] Step 302, the communication management system reassembles the packets after receiving all the data packets sent by the Beidou terminal;

[0059] Step 303, the communication management system forwards the packaged data to a third-party management platform;

[0060] Step 304, for receiving incomplete Beidou terminal data packets, the communication management system does not group packets until the reception is complete; when a new data packet (different batch from the current data packet) is received, the communication management system ...

Abstract

The invention discloses a method for implementing bidirectional transmission of third-party data by utilizing a Beidou short message, which comprises the step that: a third-party management terminal and a third-party terminal carry out bidirectional data transmission by a Beidou short message data management terminal and a Beidou terminal with a short message data communication function; the communication management terminal is used for carrying out grouping management on the Beidou terminal and carrying out management of communication modes; and the communication modes comprise unicast, multicast and announcement call. According to the invention, in a region without a GPRS, Ethernet and the like, a short message data communication function of the Beidou terminal is used, a data transmission channel is set up between the third-party terminal and the third-party management terminal, bidirectional, rapid, reliable and transparent transmission of third-party data is implemented, the method is convenient for a user to use, and maintenance cost can be reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for realizing bidirectional transmission of third-party data by using Beidou short messages. Background technique [0002] China Beidou satellite navigation system is a global satellite navigation system developed by China itself. Beidou RDSS is one of the characteristics that distinguish Beidou system from other navigation systems. Beidou RDSS can realize short message data communication between Beidou terminals similar to SMS. Therefore, using the mechanism principle of the Beidou RDSS short message, two-way data transmission between multiple Beidou terminals can be realized. [0003] At present, the Beidou commander aircraft can realize the command and dispatch of subordinate Beidou terminals, multi-level group management and data transmission functions, but it cannot be used as a data transmission medium to provide data transparent transmission services betwee...
