Problems solved by technology

[0003] A single communication network can no longer meet people's needs for communication. For example, a single power line carrier network uses lines to connect various communication networks, so that the communication between each network can only be carried out according to a predetermined path, and the surrounding physical In the case of a relatively harsh environment, the connection relationship between nodes in the network is easily affected, and it cannot be applied to long-distance communication. At the same time, when the communication channel is relatively noisy, the communication success rate and communication quality are easily affected. big impact
[0004] Generally speaking, the existing communication networks and communication methods are relatively single, and are easily limited so that it is impossible to improve the efficiency and success rate of communication.

Abstract

The present invention discloses a communication method and device for a dual-mode communication network. The dual-mode communication network includes a plurality of network nodes. The method includes: when the first network node and the second network node communicate with each other, acquire the upper All channel evaluation values ​​on the uplink direction and all channel evaluation values ​​on the downlink direction; all channel evaluation values ​​on the uplink direction are compared to obtain the communication channel with the best uplink communication quality and all channel evaluation values ​​on the downlink direction are compared Values ​​are compared to obtain the communication channel with the best downlink communication quality. The invention provides a two-way information transmission method based on a dual-mode mixed channel between communication protocol layers of a communication protocol stack, selects a communication channel with the best communication quality to transmit data, and improves the communication success rate and communication quality of a dual-mode network.
