In order to explain the technical means of the present invention, the following description will be given by way of specific examples.

Example one

The communication method of the dual-frequency repeater provided by the embodiment of the invention can be applied to the dual-frequency repeater, and as shown in fig. 1, the communication method comprises the following steps:

in the embodiment of the present invention, the dual-band repeater may use two frequency bands (2.4G and 5G) for communication, for example, data transmitted by the access node may be received through two frequency band receiving interfaces (which may be defined as a 5G frequency band receiving interface and a 2.4G frequency band receiving interface), and a bridge interface of the two frequency bands (which may be defined as a 5G frequency band transmitting interface and a 2.4G frequency band transmitting interface) may forward the data to the target node through different frequency band communication channels. The channel utilization rate of the 5G frequency band and the channel utilization rate of the 2.4G frequency band can be obtained by directly reading parameter values of the microprocessor. The access node corresponding to the 5G frequency band may be a node to which a 5G frequency band receiving interface corresponding to the 5G frequency band is accessed, and the access node corresponding to the 2.4G frequency band may be a node to which a 2.4G frequency band receiving interface corresponding to the 2.4G frequency band is accessed.

Step S102, respectively judging whether the channel utilization rate of the 5G frequency band is greater than a first threshold value and whether the channel utilization rate of the 2.4G frequency band is greater than a second threshold value;

in the embodiment of the invention, a first threshold and a second threshold are preset, and whether the channel utilization rate of the 5G frequency band is greater than the first threshold and whether the channel utilization rate of the 2.4G frequency band is greater than the second threshold are respectively judged so as to judge the busyness degree of the first frequency band and the second frequency band.

Step S103, if the channel utilization rate of the 5G frequency band is less than or equal to the first threshold and the channel utilization rate of the 2.4G frequency band is less than or equal to the second threshold, determining whether the sum of the first node number and the second node number is greater than a third threshold.

In the embodiment of the present invention, the third threshold is preset, and preferably, the third threshold may be preset to 4, and may be set to other values according to practical applications. If the channel utilization rate of the 5G frequency band is less than or equal to the first threshold value, and the channel utilization rate of the 2.4G frequency band is less than or equal to the second threshold value, which can indicate that the 5G frequency band and the 2.4G frequency band are not busy, whether the sum of the number of the first nodes and the number of the second nodes is greater than a third threshold value is judged.

in this embodiment of the present invention, if the total number of the first node number and the second node number is less than or equal to a third threshold, which indicates that the number of nodes accessed by the 5G band receiving interface and the number of nodes accessed by the 2.4G band receiving interface are small, a first idle bandwidth value of the 5G band is calculated, and a node with the largest traffic among all nodes in the 2.4G band that are smaller than the first idle bandwidth value is switched to the 5G band for data communication.

Step S105, if the sum of the first node number and the second node number is greater than the third threshold, performing a first equalization process on the first node and the second node.

In the embodiment of the present invention, if the sum of the number of the first nodes and the number of the second nodes is greater than the third threshold, which indicates that the number of the nodes accessed by the 5G frequency band receiving interface and the number of the nodes accessed by the 2.4G frequency band receiving interface reach a certain number, the first equalization processing is performed on the first nodes and the second nodes. The first balancing processing may be to perform first balancing policy processing according to node load conditions of the 5G frequency band and the 2.4G frequency band, so as to switch the communication frequency band of the access node.

Step S106, if the channel utilization rate of the 5G frequency band is greater than the first threshold and the channel utilization rate of the 2.4G frequency band is greater than the second threshold, performing a second equalization process on the first node and the second node.

In the embodiment of the present invention, if the channel utilization rate of the 5G frequency band is greater than the first threshold and the channel utilization rate of the 2.4G frequency band is greater than the second threshold, which indicates that the 5G frequency band and the 2.4G frequency band are in a busy state, the second equalization processing is performed on the first node and the second node. The second balancing processing may perform second balancing policy processing according to node load conditions of the 5G frequency band and the 2.4G frequency band, so as to switch a frequency band channel of node communication.

In an embodiment, the idle bandwidth value of the frequency band may be calculated by determining an occupied traffic value of the frequency band according to a channel utilization rate of the frequency band, and subtracting the occupied traffic value from a pre-stored maximum traffic value (for example, the maximum traffic value of the 2.4G frequency band may be 180Mbps, and the maximum traffic value of the 5G frequency band may be 600Mbps) and then multiplying the subtracted value by a preset weight coefficient, thereby determining the idle bandwidth value.

Therefore, in the embodiment of the invention, whether the channel utilization rate of the 5G frequency band is greater than the first threshold and whether the channel utilization rate of the 2.4G frequency band is greater than the second threshold can be respectively judged to judge whether the 5G frequency band and the 2.4G frequency band are in a busy state, and then whether the sum of the first node number and the second node number is greater than the third threshold is judged, so that the data received by the nodes and sent by the two frequency bands are reasonably distributed according to the node numbers accessed to the 5G frequency band and the 2.4G frequency band and the idle bandwidth values of the 5G frequency band and the 2.4G frequency band, the two frequency bands can be fully utilized, the frequency band utilization rate is improved, and the product performance and the user experience are improved to the maximum extent.

in the embodiment of the present invention, if the sum of the first node number and the second node number is greater than the third threshold, the multiple relationship between the first node number and the second node number is determined, so as to determine the relationship between the loads in the 5G frequency band and the 2.4G frequency band.

Step S402, if the number of the second nodes is larger than N times of the number of the first nodes, calculating an idle bandwidth value of a 5G frequency band and using the idle bandwidth value as a fourth idle bandwidth value, acquiring a node with a corresponding communication flow smaller than the fourth idle bandwidth value in the second nodes and using the node as a sixth node, and switching the node with the largest communication flow in the sixth node to the 5G frequency band for data communication;

in the embodiment of the present invention, if the number of the second nodes is greater than N times of the number of the first nodes, a node with the largest communication traffic among all nodes whose communication traffic in the 2.4G frequency band is smaller than the fourth idle bandwidth value is switched to the 5G frequency band for data communication.

Step S403, if the number of the first nodes is greater than N times the number of the second nodes, calculating an idle bandwidth value of the 2.4G frequency band and taking the idle bandwidth value as a fifth idle bandwidth value, acquiring a node in the first nodes whose corresponding communication traffic is smaller than the fifth idle bandwidth value and taking the node as a seventh node, and switching the node in the seventh node with the minimum communication traffic to the 2.4G frequency band for data communication.

In this embodiment of the present invention, if the number of the first nodes is greater than N times the number of the second nodes, an idle bandwidth value of the 2.4G frequency band is calculated and used as a fifth idle bandwidth value, and a node with the smallest communication traffic flow among all nodes whose communication traffic flows in the 5G frequency band are less than the fifth idle bandwidth value is switched to the 2.4G frequency band for data communication.

In one embodiment, after switching the node with the largest communication flow rate in the sixth node to the 5G frequency band for data communication, or after switching the node with the smallest communication flow rate in the seventh node to the 2.4G frequency band for data communication, the method further includes: and if the number of the first nodes plus 1 is less than or equal to N times of the number of the second nodes minus 1, calculating an idle bandwidth value of a 5G frequency band and taking the idle bandwidth value as a sixth idle bandwidth value, acquiring a node with corresponding communication flow less than the sixth idle bandwidth value in the second nodes and taking the node as an eighth node, and switching the node with the largest communication flow in the eighth node to the 5G frequency band for data communication.

In one embodiment, after switching the node with the largest communication flow rate in the sixth node to the 5G frequency band for data communication, or after switching the node with the smallest communication flow rate in the seventh node to the 2.4G frequency band for data communication, the method further includes: if the number of the first nodes plus 1 is larger than the number of the second nodes minus 1 by N times, respectively calculating an idle bandwidth value of a 2.4G frequency band as a seventh idle bandwidth value and an idle bandwidth value of a 5G frequency band as an eighth idle bandwidth value, acquiring a node of the first nodes, the corresponding communication flow of which is smaller than the seventh idle bandwidth value, as a ninth node, and acquiring a node of the second nodes, the corresponding communication flow of which is smaller than the eighth idle bandwidth value, as a tenth node; if the communication flow value of the node corresponding to the minimum communication flow in the ninth node is greater than the communication flow value of the node corresponding to the maximum communication flow in the tenth node, switching the node with the minimum communication flow in the ninth node to a 2.4G frequency band for data communication, and switching the node with the maximum communication flow in the tenth node to a 5G frequency band for data communication.

In one embodiment, after the access node switches the frequency band channel and forwards the data to the target node for communication, an Address Resolution Protocol (ARP) table of the target node is not updated, and in the ARP table of the target node, an MAC Address corresponding to an original access node IP is still an MAC Address of a relay bridge interface of the frequency band before switching. In order to trigger the update of the ARP table of the target node, a method of sending two ARP packets, namely, a General Attribute Registration Protocol (GARP) and an ARP request packet requesting the target node, to the switched frequency band is adopted, and specifically, the method includes:

in the first mode, if a frequency band is switched to a certain access node, a GARP is sent to a target frequency band sending interface. The Linux system generally updates the ARP table, but the Windows system needs the target ip to be the ARP Request packet of the Windows system, and the following second mode is needed;

in the second mode, after the frequency band is switched, the packets still sent from the original frequency band sending interface and the ip information are counted (only the ip of the same subnet is counted), and if the number of the packets sent from the original frequency band sending interface corresponding to the ip exceeds a certain threshold (for example, 128 or other values can be set), an ARP request message with the target ip being the ip, the source ip and the address being the current entry is sent to the ip through the switched frequency band channel. For Windows systems, this approach may update its ARP table.

In this embodiment, a further description is provided for the first embodiment, the second embodiment, the third embodiment, or the fourth embodiment, and the same or similar places in this embodiment as those in the first embodiment, the second embodiment, the third embodiment, or the fourth embodiment may specifically refer to the related descriptions in the first embodiment, the second embodiment, the third embodiment, or the fourth embodiment, which are not repeated herein, and as shown in fig. 5, the calculating the first idle bandwidth value of the 5G frequency band in the step S104 includes:

step S501, determining the occupied flow value of the 5G frequency band according to the channel utilization rate of the 5G frequency band.

Step S502, subtracting the occupied flow value from the pre-stored maximum flow value of the 5G frequency band, and then multiplying the subtracted value by a preset first weight coefficient to determine the first idle bandwidth value.

For convenience of understanding, the 5G band is exemplified in an application scenario, as shown in table 1 and table 2 below, the table of 2.4G and 5G channel utilization rates (thousandths) and the current communication traffic throughput value are tested by using TL-WDA6332RE 3.0.0 (dual-band repeater) in a shielded environment, a data table obtained by running a fixed value traffic with another node through an AC68 network card and reading the channel utilization rates by the repeater for multiple times is stored in advance in table 1 and table 2.

Table 12.4G lower channel utilization/throughput correspondence table

Channel utilization (‰)	Throughput(Mbps)
		120	0

		342	2*20＝40
442	3*20＝60
		545	4*20＝80
664	5*20＝100
		720	6*20＝120
790	7*20＝140
		825	8*20＝160
839	9*20＝180

Table 25G lower channel utilization/throughput correspondence table

Channel utilization (‰)	Throughput(Mbps)
		0	0
160	1*50＝50
		305	2*50＝100
400	3*50＝150
		510	4*50＝200

820	9*50＝450
		846	10*50＝500
880	11*50＝550
		930	12*50＝600

The traffic may be divided into 12 units with size, 50 units per unit, and 600Mbps for the maximum traffic supported by 5G. Assuming that the channel utilization read from the drive at this time is chanUtil 723 (unit ‰), the step of calculating 5G remaining bandwidth is:

referring to table 2, it can be seen that the sequence number i is 7 between util [ i-1] ═ 706 and util [ i ] ═ 750;

secondly, the occupied bandwidth busy of the frequency band at the time is calculated:

busyTput＝(i–1)*uint+(chanUtil–util[i-1])/(util[i]-util[I-1])*unit；

according to the calculated maximum flow maxTput that the busy cpu and the 5G can reach, 600, the current negotiation rate currtxrate of the Repeater (the negotiation rate currxrate is real-time change and can be read from the drive), 867, the 5G maximum negotiation rate maxTxRate is calculated, and the calculation formula is as follows:

IdleTput＝(maxTput–busyTput)/2*(curTxRate/maxTxRate)；

the division by 2 is because the relay cannot simultaneously transmit and receive packets, and thus the traffic is halved.
