Abstract

The invention provides a data encoding and decoding method and system for LTE-V2X standard application layer and medium. The method comprises a V2XASN1 library generation step: obtaining an open source tool, obtaining an ASN.1 code text file, taking the ASN.1 code text file as input to execute the open source tool, making and generating a C language code file, performing cross compiling on the Clanguage code file to generate a library file v2xasn1c.so, and outputting a V2XASN1 library. According to the V2XASN1 solution provided by the invention, an ASN1 UPER encoding and decoding algorithm is contained, and a developer can liberate from tedious and boring encoding and decoding work by adopting the algorithm, so that the development time is greatly saved.

Description

technical field [0001] The present invention relates to the technical field of data encoding and decoding, and in particular, relates to a data encoding and decoding method, system and medium of an LTE-V2X standard application layer. In particular, it relates to a cooperative intelligent transportation LTE V2X application layer standard data conversion method. Background technique [0002] The LTE V2X application layer data in the national standard adopts the UPER (Unaligned Packet Encoding Rules) of the ASN1 standard. There are many application layer scenarios and the data structure is complex. At present, there is no unified encoding and decoding method in the software development of embedded RSU and OBU products in the domestic industry. The conventional method is to splice data sources one by one to generate a byte data stream, and then send it through the network. In this process, the workload is heavy and errors are extremely prone to occur, and a lot of work needs to...
