[0002] Mesh (wireless mesh network) is a wireless communication technology that leverages multi-hop interconnection and mesh topology to expand user network coverage. Compared to the coverage of a single device, it can maximize the maintenance of network services in the user environment and provide comprehensive network coverage. Currently, the backhaul links between Mesh devices are either wired Ethernet transmission links or wireless Wi-Fi 2.4GHz or Wi-Fi 5GHz / 6GHz. Data cannot be transmitted simultaneously on both links. When the current backhaul link is affected by the environment, the user's network quality is significantly affected. At the same time, the user's Internet bandwidth is often limited by the bandwidth of a single backhaul link, resulting in low traffic throughput for wireless communication devices.

[0074] Example 1

[0075] Mesh is a network coverage technology that can expand the user's network coverage. Compared with the coverage of a single device, it can ensure that the network services in the user environment are normal and the network coverage has no dead spots. Compared with the traditional relay and extender methods, it can ensure that the roaming effect of the user's wireless signal between access devices is low latency and high bandwidth, thereby improving the Internet experience. In the existing Mesh device communication method, the communication link between Mesh devices, that is, the backhaul link, is either wired or Wi-Fi 2.4G or Wi-Fi 5G / 6G, and two links cannot transmit data at the same time. Therefore, it is difficult for the existing technology to fully utilize the bandwidth of MESH devices. Therefore, the Internet bandwidth on the slave device is often limited by the bandwidth of the backhaul link. Therefore, there is a problem of low traffic throughput of wireless communication devices.

[0076] The embodiment of the present application provides a backhaul link selection method. In the first embodiment of the backhaul link selection method of the present application, referring to Figure 1 , the backhaul link selection method includes:

[0077] Step S10: After the wireless mesh network is successfully established, each backhaul link is established between the network node in the wireless mesh network and the upper-level device of the network node;

[0078] Step S20, classifying each of the backhaul links into different environmental interference levels based on the current received indication signal strength and transmission rate of each of the backhaul links;

[0079] Step S30 : selecting each target backhaul link according to the type of each backhaul link, the environmental interference level, and the current received indication signal strength, wherein the target backhaul link is used for communication between the network node and the upper-level device.

[0080] In the embodiment of the present application, it should be noted that the wireless mesh network (Mesh) includes 5 network nodes. When the user communicates on the network, there will be a network node as a node that directly communicates with the user's terminal device, and the other network nodes serve as backup or transit nodes. The network node in step S10 is the node directly connected to the user's terminal device. The upper-level device can be a group control device connected to the network node, or it can be other transit network nodes for receiving and

[0081] Processing messages sent from the terminal device to the network node; when establishing each return link between the network node and the upper device 0, through VLAN (Virtual Local Area Network, Virtual Bureau

[0082] The WLAN) technology allocates a separate VLAN to each of the backhaul links to avoid interference between the backhaul links during data transmission; the backhaul links include wired backhaul links and wireless backhaul links, namely WiFi backhaul links, including 2.4G frequency bands and 5G frequency bands; wherein the

[0083] The environmental interference level can be set by the user according to the actual situation. The environmental interference level of each backhaul link in the current situation can be determined according to the current reception indication signal strength range and the corresponding transmission rate range corresponding to the five levels of environmental interference. In practice, since the wired backhaul link (Ethernet backhaul link) is less affected by environmental factors, the environmental interference level is not divided for the wired backhaul link. Among the backhaul links, if there is a wired backhaul link, the wired backhaul link is set as the backhaul link with the highest priority.

[0084] As an example, steps S10 to S30 include: when the Mesh network is detected to be successful,

[0085] Perform configuration synchronization based on the Mesh protocol configuration synchronization process and protocol specifications to obtain the backhaul information corresponding to each backhaul link, wherein the backhaul information includes the SSID (wireless network name), password, and encryption method of the 2.4G band backhaul link and the 5G band backhaul link.

[0086] Based on the Back haul information to establish the wireless mesh network network node and the network node of the upper device 5 each backhaul link, and through VLAN technology for each backhaul link points

[0087] A separate virtual network segment is configured; the current received indication signal strength and transmission rate of each of the backhaul links are detected, and a mapping table of the value range of the indication signal strength and transmission rate and the environmental interference level is obtained; based on the current received indication signal strength and transmission rate of each of the backhaul links

[0088] and the mapping table, dividing each of the backhaul links into different environmental interference levels; determining whether there is a wired backhaul link in each of the 0 backhaul links; if so, setting the wired backhaul link as the first target backhaul link, and selecting each target backhaul link from each of the wireless backhaul links according to the environmental interference level of each of the wireless backhaul links; if not, selecting each target backhaul link from each of the wireless backhaul links according to the environmental interference level of each of the wireless backhaul links and the corresponding current received indication signal strength.

[0089] The step of establishing each backhaul link between the network node in the wireless mesh network and the upper-level device of the network node includes:

[0090] Step S11, performing configuration synchronization according to the protocol of the wireless mesh network to obtain backhaul link information corresponding to each backhaul link;

[0091] Step S12: establishing a connection between the network node and an upper-level device of the network node based on each of the backhaul links based on the backhaul link information;

[0092] Step S13: splitting the data in each of the return links by using virtual local area network technology.

[0093] In the embodiment of the present application, it should be noted that each of the backhaul links includes a wired backhaul link and a wireless backhaul link. Figure 2In practice, both wired and wireless backhaul links can be retained at the same time. If the network node (Agent1) and the upper-level device (Controller / Agent) maintain a wired connection at the same time and the bandwidth meets the requirements, only the wired backhaul link (Ethernet) can be retained. The virtual local area network (VLAN) technology is a network segmentation technology that is not restricted by the physical location of network users and is based on user needs. That is, a separate VLAN is assigned to each backhaul link to achieve broadcast domain isolation between different VLANs to prevent loops. For example, by borrowing the VLAN aggregation method, super-VLAN and sub-VLAN technology can be used to process multi-link Back hual. Sub-VLAN can be used to isolate broadcast domains, and super-VLAN is used for VLAN aggregation. Sub-VLAN is associated with the corresponding super-vlan, and super-vlan aggregates sub-vlan data. If necessary, super-vlan allows one IP network segment to be used for multiple VLANs.

[0094] As an example, steps S11 to S13 include: after the Mesh networking specification is successfully established, executing the configuration synchronization process and protocol specifications based on the Mesh protocol corresponding to the Mesh networking to ensure data synchronization; obtaining back haul information corresponding to the 2.4G band and the 5G band, such as the network name, encryption method and password of the network cable; establishing a 2.4G band backhaul link and a 5G band backhaul link between the network node and the upper device of the network node based on each of the back haul information; and using VLAN technology to divert data from the 2.4G band backhaul link and the 5G band backhaul link to isolate the broadcast domains between the backhaul links to prevent mutual interference.

[0095] The step of classifying each of the backhaul links into different environmental interference levels based on the current received indication signal strength and transmission rate of each of the backhaul links includes:

[0096] Step S21, obtaining the current received indication signal strength range and transmission rate range corresponding to each of the environmental interference levels;

[0097] Step S22 , classifying each backhaul link into different environmental interference levels according to the current received signal strength, transmission rate, and current received signal strength range and transmission rate range corresponding to each environmental interference level of each backhaul link.

[0098] In the embodiment of the present application, it should be noted that the current received signal strength indicator (RSSI) range and the transmission rate range corresponding to each of the environmental interference levels are formulated based on the RSSI and transmission rate corresponding to each backhaul link obtained under preset environmental interference conditions, and the current received signal strength value range and the transmission rate value range corresponding to each environmental interference level are formulated as a reference, wherein each of the environmental interference levels includes at least one of a low interference level, a medium interference level and a high interference level, which is used to characterize the degree to which the backhaul link is affected by the environment in the current environment.

[0099] As an example, steps S21 to S22 include: obtaining the value range of the current received indication signal strength and the value range of the transmission rate corresponding to the low interference level, the medium interference level and the high interference level respectively; detecting the current received indication signal strength and the transmission rate of each backhaul link; determining the environmental interference level of each backhaul link based on the current received indication signal strength and the transmission rate of each backhaul link and the value range of the current received indication signal strength and the value range of the transmission rate corresponding to the low interference level, the medium interference level and the high interference level respectively.

[0100] The type of the backhaul link includes at least a wireless backhaul link;

[0101] The step of selecting each target backhaul link according to the type of each backhaul link, the environmental interference level, and the current received indication signal strength includes:

[0102] Step S31, determining whether there is a wired backhaul link in each of the backhaul links;

[0103] Step S32: If so, the wired backhaul link is set as the first target backhaul link, and each target backhaul link is selected according to the environmental interference level of each wireless backhaul link;

[0104] Step S33: If no target backhaul links exist, then select each target backhaul link according to the environmental interference level of each wireless backhaul link and the corresponding current received indicated signal strength.

[0105] In the embodiment of the present application, it should be noted that, among the multiple backhaul links between the network node and the upper-level device corresponding to the network node, if there is a wired backhaul link (Ethernet backhaul link), the wired backhaul link is set as the first target backhaul link. If there is other wireless backhaul link with better communication quality, the wireless backhaul link can also be used as the second target backhaul link; when there is no wired backhaul link in each of the backhaul links, a wireless backhaul link must be used. Among them, when the impact interference level of each of the wireless backhaul links is a high interference level, it is necessary to select the target backhaul link based on the current received signal strength (RSSI) of each of the wireless backhaul links.

[0106] As an example, steps S31 to S33 include: determining whether there is a wired backhaul link among the backhaul links between the network node in the wireless mesh network and the upper device of the network node; if there is a wired backhaul link among the backhaul links between the network node in the wireless mesh network and the upper device of the network node, setting the wired backhaul link as the first target backhaul link; determining a second target backhaul link according to the environmental interference level of each of the wireless backhaul links; if there is no wired backhaul link among the backhaul links between the network node in the wireless mesh network and the upper device of the network node, determining whether the environmental interference level of each of the wireless backhaul links is a high interference level; if the environmental interference level of each of the wireless backhaul links is a high interference level, selecting the first target backhaul link according to the current received signal strength indicator (RSSI) of each of the wireless backhaul links; if the environmental interference level of each of the wireless backhaul links is not all a high interference level, selecting the first target backhaul link according to the environmental interference level of each of the wireless backhaul links.

[0107] The wireless backhaul link includes at least one of a 2.4G frequency band backhaul link and a 5G frequency band backhaul link, and the environmental interference level includes at least one of a low interference level, a medium interference level, and a high interference level. The degree of environmental impact represented by the medium interference level is higher than the degree of environmental impact represented by the low interference level, and lower than the degree of environmental impact represented by the high interference level.

[0108] The step of selecting each target backhaul link according to the environmental interference level of each wireless backhaul link includes:

[0109] Step S321: If the environmental interference levels of the 2.4 GHz band backhaul link and the 5 GHz band backhaul link are both high interference levels, suspending the use of the 2.4 GHz band backhaul link and the 5 GHz band backhaul link;

[0110] Step S322: If the environmental interference level of the 5G band backhaul link is not higher than the environmental interference level of the 2.4G band backhaul link, and the environmental interference level of the 5G band backhaul link is not a high interference level, then the 5G band backhaul link is set as the second target backhaul link;

[0111] Step S323: If the environmental interference level of the 5G frequency band backhaul link is higher than the environmental interference level of the 2.4G frequency band backhaul link, the 2.4G frequency band backhaul link is set as the second target backhaul link.

[0112] In the embodiment of the present application, it should be noted that, in practice, if the environmental interference levels of the 2.4G band backhaul link and the 5G band backhaul link are both high interference levels, the 2.4G band backhaul link and the 5G band backhaul link, whichever has a higher currently received indication signal strength, can also be used as the second target link; when the environmental interference level of the 2.4G band backhaul link is a low interference level, and the environmental interference levels of the 5G band backhaul link are both medium interference levels, the 2.4G band backhaul link can be set as the second target link. The target backhaul link is set as the 5G band backhaul link, and the 5G band backhaul link is set as the third target backhaul link; if the environmental interference level of the 5G band backhaul link and the environmental interference level of the 2.4G band backhaul link are both low interference levels or medium interference levels, the 5G band backhaul link is set as the second target backhaul link, and the 2.4G band link can also be set as the third target backhaul link. The above backhaul link setting rules can be enabled or disabled by the user according to actual needs. For example, when the bandwidth demand is high, the above setting rules can be enabled; Figure 3 The diagram shows how each network node (Agent1-Agent6) is connected to the upper-level device (Controller / Agent) using different backhaul link methods. The wired backhaul link includes an Ethernet backhaul link, and the wireless backhaul link includes a 2.4 GHz band backhaul link and a 5 GHz band backhaul link.

[0113] As an example, steps S321 to S323 include: if the environmental interference level of the 2.4G band backhaul link is a high interference level, and the environmental interference levels of the 5G band backhaul link are both high interference levels, then suspending the use of the 2.4G band backhaul link and the 5G band backhaul link; if the environmental interference level of the 5G band backhaul link and the environmental interference level of the 2.4G band backhaul link are both low interference levels or medium interference levels, then setting the 5G band backhaul link to the second target backhaul link; if the environmental interference level of the 5G band backhaul link is a medium interference level, and the environmental interference level of the 2.4G band backhaul link is a high interference level, then setting the 5G band backhaul link to the second target backhaul link.

[0115] The step of selecting each target backhaul link according to the environmental interference level of each wireless backhaul link and the corresponding current received indication signal strength includes:

[0116] Step S331: If the environmental interference levels of the 2.4 GHz band backhaul link and the 5 GHz band backhaul link are both high interference levels, the wireless backhaul link with the stronger currently received indication signal strength between the 2.4 GHz band backhaul link and the 5 GHz band backhaul link is set as the first target backhaul link;

[0117] Step S332: If the environmental interference level of the 5G band backhaul link is not higher than the environmental interference level of the 2.4G band backhaul link, and the environmental interference level of the 5G band backhaul link is not a high interference level, then the 5G band backhaul link is set as the first target backhaul link;

[0120] As an example, steps S331 to S333 include: if the environmental interference levels of the 2.4G band backhaul link and the 5G band backhaul link are both high interference levels, determining whether the current reception indication signal strength of the 2.4G band backhaul link is higher than the current reception indication signal strength corresponding to the 5G band backhaul link; if so, setting the 2.4G band backhaul link as the first target backhaul link; if not, setting the 5G band backhaul link as the first target backhaul link; if the environmental interference level of the 5G band backhaul link and the environmental interference level of the 2.4G band backhaul link are both low interference levels or medium interference levels, setting the 5G band backhaul link as the first target backhaul link; if the environmental interference level of the 5G band backhaul link is a medium interference level, and the 2.4G band backhaul link is .4G band backhaul link is a high interference level, the 5G band backhaul link is set as the first target backhaul link; if the environmental interference level of the 5G band backhaul link is a low interference level, and the environmental interference level of the 2.4G band backhaul link is a medium interference level, the 5G band backhaul link is set as the first target backhaul link; if the environmental interference level of the 2.4G band backhaul link is a low interference level, and the environmental interference level of the 5G band backhaul link is a medium interference level, the 2.4G band backhaul link is set as the first target backhaul link; if the environmental interference level of the 2.4G band backhaul link is a medium interference level, and the environmental interference level of the 5G band backhaul link is a high interference level, the 2.4G band backhaul link is set as the first target backhaul link.

[0121] The step of selecting each target backhaul link according to the environmental interference level of each wireless backhaul link and the corresponding current received indication signal strength further includes:

[0122] Step S334: If the environmental interference level of the 5G band backhaul link and the environmental interference level of the 2.4G band backhaul link are both low interference levels or medium interference levels, the 5G band backhaul link is set as the first target backhaul link, and the 2.4G band link is set as the second target backhaul link;

[0123] In step S335, if the environmental interference level of the 5G band backhaul link is a medium interference level and the environmental interference level of the 2.4G band backhaul link is a low interference level, the 2.4G band link is set as the first target backhaul link, and the 5G band backhaul link is set as the second target backhaul link.

[0124] In the embodiment of the present application, it should be noted that the embodiment of the present application provides a method for selecting a second target backhaul link when there is no wired backhaul link in the backhaul links and the bandwidth requirement is high.

[0125] As an example, steps S334 to S335 include: if the environmental interference level of the 5G band backhaul link and the environmental interference level of the 2.4G band backhaul link are both low interference levels, the 5G band backhaul link is set as the first target backhaul link, and the 2.4G band link is set as the second target backhaul link; if the environmental interference level of the 5G band backhaul link and the environmental interference level of the 2.4G band backhaul link are both medium interference levels, the 5G band backhaul link is set as the first target backhaul link, and the 2.4G band link is set as the second target backhaul link; if the environmental interference level of the 5G band backhaul link is a medium interference level, and the environmental interference level of the 2.4G band backhaul link is a low interference level, the 2.4G band link is set as the first target backhaul link, and the 5G band backhaul link is set as the second target backhaul link.

[0126] An embodiment of the present application provides a backhaul link selection method. First, after a wireless mesh network is successfully established, backhaul links are established between a network node in the wireless mesh network and a superior device of the network node. Then, based on the current received indication signal strength and transmission rate of each backhaul link, each backhaul link is divided into different environmental interference levels. Finally, target backhaul links are selected based on the type of each backhaul link, the environmental interference level, and the current received indication signal strength. The target backhaul link is used for communication between the network node and the superior device. In the technical solution of the embodiment of the present application, multiple backhaul links are simultaneously established between the network node and the superior device, and the corresponding environmental interference level is determined based on the status of each backhaul link to determine the target backhaul link based on the environmental interference level. This ensures that the backhaul link in the current optimal state is used as the primary link for network communication, reduces the impact of environmental interference on communication quality, overcomes the technical defect that the user's Internet bandwidth is limited by the bandwidth of a single backhaul link, and improves the traffic throughput of the wireless communication device.
