Description

Information transmission method, device, electronic equipment and storage medium Technical Field The disclosure relates to the field of communication technologies, and in particular, to an information transmission method, an information transmission device, electronic equipment and a storage medium. Background In future everything intelligent network, network nodes tend to be intelligent, network nodes extremely intelligently lead to rapid expansion of information space and even dimension disasters, the difficulty of representing information bearing space is aggravated, traditional network service capacity and high-dimension information space are difficult to match, the data volume of communication transmission is overlarge, and an information service system cannot continuously meet the requirements of complex, diversified and intelligent information transmission of people. With the development of society and the progress of age, communication technology and artificial intelligence are continuously developed. The intelligent network is a communication technology combining artificial intelligence with communication technology, and improves the communication performance. The service information is encoded, propagated and decoded through the artificial intelligent model, so that the data transmission quantity in the communication service can be obviously reduced, and the information transmission efficiency is greatly improved. These models are relatively stable and have reusability and transmissibility. The propagation and multiplexing of the model are beneficial to enhancing the network intelligence, reducing the cost and the resource waste, and forming an intelligent network with intelligent nodes and extremely simple network. Conventional syntactic communication requires that the decoding information of the receiving end is strictly consistent with the encoding information of the transmitting end, i.e. that the error-free transmission at the bit level is realized. In the semantic communication of the intelligent network, the semantic communication does not require strict matching of the decoding sequence and the encoding sequence, and only requires matching of the semantic information recovered by the receiving end and the semantic information of the transmitting end. As the semantic communication can further compress the transmission content, the error requirement of information transmission in the system is newly defined, the fault tolerance of the information transmission is increased, the transmission bottleneck of the classical grammar communication system is hopeful to be broken through, and a new solution idea is provided for the evolution of the new generation wireless communication system. The research of semantic information is becoming a focus of academic circles, and data transmission based on the semantic information is a very competitive key technology. However, the successful construction of the semantic communication system necessarily requires that the support is provided for the transmission of information (such as text, images, video and the like) of various data types at the same time, namely, the semantic communication system is standardized for the transmission standards of various data types, and the existing research does not realize the integral planning of the semantic communication transmission flow. Under the background, the transmitted data are synchronized through the semantic library, so that semantic coding and transmission flow of various data can be standardized, and cross-modal communication of various data types between various devices can be met.
