Description

Technical Field

[0001] The present invention relates to the technical field of dual-mode communication data transmission, and particularly to a data transmission method and device for power line carrier wireless dual-mode communication. Background Art

[0002] At present, in modern communication networks, a single communication channel often fails to meet the requirements of various services. For example, although the power line carrier channel uses existing power lines for data transmission and has advantages such as low investment and wide coverage, it has problems such as susceptibility to interference and unstable transmission quality. The wireless channel, although highly flexible, is greatly affected by geographical environment and weather factors, and signal coverage and transmission performance may be limited in some complex environments. Therefore, integrating the power line carrier channel and the wireless channel can give full play to the advantages of both and achieve more reliable and efficient communication. In the integrated network, it is necessary to comprehensively utilize the advantages of the power line carrier channel and the wireless channel and overcome their respective deficiencies to achieve the best data transmission. To meet users' high-quality experience requirements for various communication services, it is necessary to improve the transmission performance of service data, such as reducing latency and error rate. By achieving the optimal allocation of data streams in the power line carrier channel and the wireless channel, the utilization efficiency of channels in the network and the transmission performance of service data can be improved, thereby enhancing the overall transmission performance of service data.

[0003] However, there is currently no data transmission method and device for power line carrier wireless dual-mode communication to achieve the optimal allocation of data streams in the power line carrier channel and the wireless channel at the current moment and maximize the performance of the integrated network.

[0004] Therefore, the present invention proposes a data transmission method and device for power line carrier wireless dual-mode communication. Summary of the Invention

The quantization of the transmission performance of each type of communication for each sub-path of the transmission path at the current moment is realized. Furthermore, according to the transmission performance evaluation values of all types of communication for all sub-paths of the transmission path at the current moment, the data flow distribution diagram and data flow distribution line of the transmission path at the current moment are obtained, which is convenient for obtaining the data flow distribution ratio of all types of communication in the subsequent process. According to the data flow distribution diagram and data flow distribution line of the transmission path at the current moment, the data flow distribution ratio of all types of communication for the transmission path at the current moment is obtained, and the accurate quantization of the allocation share of each type of communication in the transmission path at the current moment during data flow allocation is realized. Finally, according to the data flow distribution ratio of all types of communication for the transmission path at the current moment, the optimal data transmission result of the transmission path at the current moment is obtained, realizing the optimal allocation of the data flow at the current moment in the power line carrier channel and the wireless channel, improving the utilization efficiency of the channels in the network and the transmission performance of service data, and maximizing the performance of the converged network.
