and step S32, transmitting the communication content with high real-time performance to other 5G backhaul devices or a central base station by adopting the power carrier communication channel.
That is, when the wireless communication channel is unstable or unavailable, the central base station uses the power line carrier communication channel as the route of the 5G backhaul device, and when the 5G backhaul device needs to transmit communication information using the circuit carrier communication channel, the communication content with high real-time performance is transmitted using the power line carrier communication information to ensure that the communication information is transmitted in time, and the communication content with low real-time performance is stored in the memory of the 5G backhaul device (the th memory in the above 5G backhaul device embodiment) first, and when the route information of the 5G backhaul device is updated to the wireless communication channel route information, the communication content with low real-time performance is transmitted using the wireless communication channel.
The communication information received by the 5G backhaul device from the equipment at the user side is classified into a plurality of levels according to the importance and the real-time performance of the communication information, the low-capacity user data with high requirement and high real-time performance level is determined as the communication content with high embodiment, and the other low-capacity user data with high importance and low real-time performance level is determined as the communication content with low real-time performance level. Therefore, the power carrier communication circuit is adopted to transmit the real-time information with small capacity, the timeliness of information transmission is ensured, and the information with large capacity is stored in the memory, so that the energy consumption of the power carrier is reduced.
For another example, when the target communication channel is a wireless communication channel, the step of transmitting the communication information to another 5G backhaul device or a central base station using the target communication channel includes:
step S33, when the communication content with low real-time performance is stored in the memory, the wireless communication channel is adopted to transmit the communication information and the communication content with low real-time performance stored in the memory to other 5G backhaul devices or central base stations, wherein, when the power carrier communication channel is adopted for communication, the communication content with low real-time performance in the communication information is stored in the memory;
and step S34, when the memory does not store the communication content with low real-time performance, the received communication information is transmitted to other 5G backhaul devices or the central base station by adopting the wireless communication channel.
If the target communication channel is a wireless communication channel, that is, the current wireless communication channel data of the 5G backhaul device is stably transmitted, at this time, the 5G backhaul device directly uses the wireless communication channel to perform information transmission. The communication information may include communication information received by the 5G backhaul device in real time and transmitted by the user terminal or other 5G backhaul devices, or may also include communication information stored in a memory when the wireless communication channel is unstable (unavailable), that is, after a target communication channel of the 5G backhaul device is a wireless communication channel, if new communication information is received and communication content with low real-time performance stored in the memory during communication using power line carrier is stored, the new communication information and the previously stored communication content with low real-time performance are sent out in time to prevent information retention; and if new communication information is received and the communication content is not stored in the memory, sending out the new communication information in time.
It can be understood that, in the embodiment of the present invention, the wireless communication channel is preferentially used for transmitting the communication information, and when the wireless communication channel is not available, the power carrier communication channel is used for transmitting the information.
Based on the network topology system, the present invention further provides a communication method of the network topology system, and referring to fig. 6, the communication method of the network topology system includes the following steps:
step S100, after the 5G return device obtains the state information, the state information is sent to a central base station by adopting a power line carrier communication channel;
step S200, the central base station receives the status information sent by the 5G backhaul device, generates routing information according to the status information, and sends the routing information to the 5G backhaul device.
The network topology system comprises a central base station and a plurality of 5G backhaul devices, wherein the 5G backhaul devices are connected with the central base station directly or through other 5G backhaul devices, and the 5G backhaul devices are communicated with the central base station through a wireless communication channel or a power carrier communication channel.
In this embodiment, the 5G backhaul device counts its own status information in real time or at regular time, and sends the status information to the central base station by using the power carrier communication channel, where the status information is sent by using the power carrier communication channel, so that the status information can be timely and stably transmitted to the central base station. And the central base station generates routing information of the 5G backhaul device according to the state information of the 5G backhaul device and sends the routing information to the 5G backhaul device.
And when the wireless communication channel of the 5G backhaul device is determined to be unstable according to the state information, taking the power carrier communication channel as the routing information of the 5G backhaul device. And when the power carrier communication channel of the 5G backhaul device is determined to be shifted according to the state information, using the wireless communication channel as the routing information of the 5G backhaul device, or when the wireless communication channel of the 5G backhaul device is determined to be recovered to be stable according to the state information, using the wireless communication channel as the routing information of the 5G backhaul device.
It can be understood that, the network topology system has a plurality of 5G backhaul devices, and the positions of the respective 5G backhaul devices are different, so that when the wireless communication channels of some 5G backhaul devices are unstable and some wireless communication channels are stable, the central base station determines different routing information according to the information states of the different 5G backhaul devices, so that the 5G backhaul devices backhaul the communication information with the optimal path.
The network topology system in the embodiment can always perform signal transmission in an optimal communication mode, and the data transmission reliability of the network topology system is high.
