In this way, if conventional text communication is used, it is difficult for 120 Chinese characters (including punctuation marks) to describe complex information content. If multiple short messages are separated, the information will be sent incompletely, that is, when a short message occurs When the text is lost, the content of the information communication will be missing, and the exact meaning of the information cannot be read
Especially in emergency communication situations, the lack of information communication content can have very serious consequences
Therefore, in routine use, if the standard short message communication protocol provided by the Beidou system is used directly, sufficient information cannot be effectively transmitted
[0007] To sum up, the number of Chinese characters carried in the existing short messages based on Beidou communication is too small

[0028] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.
[0029] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings. Such as figure 1 As shown, Embodiment 1 of the present invention provides a basic flowchart of a short message reading method based on Beidou communication:
[0030] S101. Decode the received short message by using the preset Beidou first-level protocol to obtain the service data segment of the short message;
[0031] S102, use the preset Beidou secondary protocol to decode the business data segment to obtain the standard business information code, the standard business information code includes the location information code and the situation information code, the Beidou secondary protocol defines the standard business in the business data segment The l...

The invention relates to the field of network communication, and specifically relates to a short message reading method based on Beidou communication. According to the short message reading method based on the Beidou communication, a position of a standard service information code for carrying service information is arranged in a Beidou secondary protocol, and meaning corresponding to the standard service information code is also defined, under the condition that a Beidou primary code is not changed, a terminal and a network end can determine the meaning expressed by a specific code according to a code in a short message, and through omitting the part for describing the code, one short message can carry more service information, such that the short message for the Beidou communication can carry more Chinese characters, and the disadvantage in the prior art is solved.
Description
technical field [0001] The invention relates to the field of network communication, in particular to a short message reading method based on Beidou communication. Background technique [0002] China's Beidou Navigation Satellite System ("BDS") is a global satellite positioning and communication system developed by my country. It is following the US Global Positioning System (Global Positioning System-"GPS") and the Russian Global Satellite Navigation System After the third full-fledged satellite navigation system. The system consists of a space terminal, a ground terminal and a user terminal. It can provide all kinds of users with high-precision, high-reliability positioning, navigation, and timing services all-weather and all-weather around the world, and has the ability to communicate with short messages. Regional navigation, positioning and timing capabilities, the positioning accuracy is better than 20m, and the timing accuracy is better than 100ns. [0003] Among ...
