Coding/decoding method for communication system information and coder/decoder

Abstract

This invention discloses decoding method and its coding device of communication system, which comprises the following steps: defining communication system message each element logic relationship into one data structure as comment by elements; defining relative data structure type according to information element property; when coding communication information, according to data structure and other types to input data structure coder for each data structure element to get said communication data; when decoding communication message, according to data structure and other types to read communication system data flow to read data structure element for decoding to get the communication system data.

Description

Technical field [0001] The present invention relates to coding and decoding technology in the communication field, and in particular to a coding and decoding method, encoder and decoder of communication system messages. Background technique [0002] The messages in the communication system are generally described and defined in the form of documents, which are converted into a format that the computer can process by the computer, so as to realize the encoding and decoding of the message. In the encoding process, the computer converts the communication system message into a bit stream that can be processed by the communication system equipment; in the decoding process, the computer decodes the message bit stream into a message description that people can recognize. [0003] The communication system message contains several information elements (Information Element, IE), which are used to carry different types of information. IEs have different attributes, such as optional, require...
