However, if the decoding library is sent at the same time for each transmission, the bandwidth will be seriously wasted; if the decoding library is sent after the communication fails due to the identification error of the receiver, the transmission time and transmission resources of the first transmission will be wasted, and the transmission time will be reduced. communication efficiency

Embodiment Construction
[0038]As mentioned above, each communication system has specific encoding rules, and the receiver may not be able to correctly identify the characters in the received codeword, resulting in communication failure. In the existing technology, in order for the receiver to correctly identify the characters in the codeword, it is necessary to prepare and send the decoding library in advance according to the different encoding standards of the sender and the receiver, so that the other party can pass the Code conversion can be correctly identified and decoded smoothly, but if the decoding library is sent at the same time for each transmission, it will seriously waste bandwidth; if the decoding library is sent after the receiver has an identification error and the communication fails, the first transmission will be wasted The transmission time and transmission resources are reduced, and the communication efficiency is reduced.

An encoding method and device, the method comprising the following steps: according to a plurality of communication systems used to transmit data to be transmitted, obtaining common characters that can be recognized by the plurality of communication systems; selecting at least a part of the common characters As basic characters, different codewords are constructed based on the basic characters to obtain a codebase, and different codewords correspond to different characters; and the data to be transmitted is encoded by using the codebase. The embodiments of the present invention can enable the receiver to correctly identify the characters in the received codeword without ambiguity, and then save the received information, thereby improving communication efficiency.
Description
technical field [0001] The present invention relates to the communication field, in particular to an encoding method and device. Background technique [0002] At present, each communication system has specific encoding rules. For example, the mail system adopts Base64 encoding, the website protocol adopts Http encoding, and the short message adopts mobile communication encoding standards, etc. Although binary encoding and decoding methods can be used to convert the codewords of each system into binary bits stream, and then perform physical layer transmission to other systems, but the receiver may not be able to correctly identify the characters in the received codeword, resulting in communication failure. Specifically, multiple characters correspond to different binary bit streams in different systems, and many characters have different meanings in different systems, so that when the receiver receives the binary bit stream carrying the transmission information, it may Misre...
