Description

Technical Field

[0001] This application relates to the field of network management technologies, and specifically to a method and apparatus for managing a mesh network topology, and an electronic device. Background Art

[0002] With the development of whole-house intelligent applications, there are more and more devices with gateway capabilities such as central control screens and speakers in the whole-house space. At the same time, considering factors such as wiring, cost, and local control response, the local and timely response advantages of the mesh network (Mesh network) make it gradually become the mainstream. Especially, gateway devices have multiple communication integration capabilities and can combine other reliable connection methods to further enhance the capabilities of the Mesh network.

[0003] In a physical space, there may be multiple gateway devices (such as central control screens, speakers, etc.) and multiple node devices (such as smart lights, smart curtains, smart locks, etc.) in the Mesh network topology. The node devices communicate with the server (such as the cloud IoT cloud platform, application system server, etc.) through the gateway devices. The gateway devices allow the node devices to upload data, and remote instructions can also be sent to the local node devices through the gateway devices. For the node devices, the node messages are sent in a broadcast manner, and as long as they are within the Mesh network range (within the communication range or within the range that can be covered through relays), all gateway devices can receive them. Similarly, when the gateway devices send messages, they also send them in a broadcast manner, and all node devices within the network range can receive the messages. Currently, when the node data of the local Mesh network needs to be synchronized to the server, each gateway device that receives the message has to report the data to the server; when the server sends messages through the gateway devices, multiple paths will also be formed for sending based on the Mesh network topology to ensure network reliability.

[0004] However, the inventors found that the above existing Mesh network topology management solutions have at least the following problems: 1) When the node data of the local Mesh network needs to be synchronized to the server, since each gateway device has to report the data to the server, a large amount of redundant data will be reported to the server, thereby increasing the data communication cost. And since the server has to handle abnormal problems such as a large amount of data aggregation, the service cost of the server is increased; 2) When the server sends messages through the gateway devices, due to the Mesh network topology, each gateway device has to send messages to the node devices in a broadcast manner. If the multiple sending paths formed are in the same physical space, it will cause a large amount of interference to the wireless signals in the air, resulting in wireless conflicts, transmission failures, network congestion, and transmission delays.

[0005] In summary, when a node device sends data to a server, how to reduce the data communication cost and the service cost of the server; when the server sends data to a node device, how to reduce network congestion to improve data transmission efficiency are problems that urgently need to be studied and tackled.

[0082] In the following description, many specific details are set forth in order to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar promotions without departing from the connotation of this application. Therefore, this application is not limited by the specific implementations disclosed below.

[0083] In this application, a mesh network topology management method and apparatus, and an electronic device are provided. Various solutions will be described in detail in each of the following embodiments.

[0084] First Embodiment

[0085] Please refer to Figure 1 , which is a flow chart of the mesh network topology management method of this application. In this embodiment, the method may include the following steps:

[0086] Step S101: Obtain first network information between multiple gateway devices and node devices respectively.

[0087] The mesh network topology management method provided in the embodiments of this application is used for gateway devices in a mesh network. A mesh network is a Mesh network, which includes multiple gateway devices and multiple node devices, and each gateway device can be the execution subject of the method provided in the embodiments of this application.

[0088] A Mesh network does not rely on a certain central device (hub device) and has the characteristic of decentralization. Even if some nodes fail, information can still be transmitted through other nodes, and it can achieve powerful concurrent multicast communication in a network with thousands of nodes, with relatively high communication efficiency and stability. For example, the Mesh network is a Bluetooth Mesh network, which uses low-power Bluetooth as the information carrier method. Through self-organizing network technology, Bluetooth devices can be used as gateway devices. By establishing a low-power network for multi-to-multi device communication, multiple nodes in the same physical space can be closely connected together to achieve interconnection and interoperability between devices. Each device can directly or indirectly connect to other devices, and the signal is transmitted through nearby devices to form a stable full-coverage communication network. The Bluetooth gateway device and the Bluetooth node device in the Bluetooth Mesh network communicate via Bluetooth. The Bluetooth node device communicates with the server through the Bluetooth gateway device.

[0089] The gateway device in a Mesh network is a relatively powerful network device capable of managing the local network. Gateway devices usually have multiple communication integration capabilities, that is, they can communicate with node devices via short-range wireless means, and can also combine other reliable connection methods such as network cables, wireless WiFi, or power lines to further enhance the capabilities of the Mesh network. The gateway device enables node devices to upload data, and remote instructions can also be sent to local node devices through the gateway device. In practical applications, the gateway device can be a central control screen, smart speaker, smart TV, etc. At the same time, the gateway device itself can also act as a node device, such as a smart speaker, smart TV, etc.

[0090] Node devices in a Mesh network can communicate with the gateway device via short-range wireless means. If a node device only has limited communication integration capabilities, it cannot act as a gateway device, such as smart lights, smart curtains, smart door locks, etc. If a node device has multiple communication integration capabilities, it can also act as a gateway device, such as a smart speaker, smart TV, etc.

[0091] The gateway device in a Mesh network enables node devices to upload data to the server, and at the same time, remote instructions from the server can also be sent to local node devices through the gateway device. The server can be a device that provides services to node devices, such as the cloud platform (abbreviated as the cloud) in the Internet of Things (IoT), the server of any application system, etc.

[0092] Taking the Internet of Things as an example, users can remotely control smart devices (such as air purifiers, etc.) in their homes through an application installed in the user device (such as a mobile phone APP). The smart devices can upload device data to the IoT cloud platform, and the IoT cloud platform can send control instructions to the smart devices. As Figure 2 shown, multiple smart devices in the user's home form a Mesh network, which includes multiple gateway devices, such as Figure 2 the central control, central control 1, central control 2, central control 3, and the mobile phone App in it. In addition, the network also includes multiple node devices, such as Figure 2 T1 to T24 in it, among which node devices with triggering capabilities such as switch panels, and devices with execution capabilities such as smart lights, etc. As Figure 3 shown, the four central controls (the aforementioned central control, central control 1, central control 2, central control 3) in the same physical space can be connected through communication methods such as network cables, wireless WiFi, or power lines to transmit data to each other.

[0093] Any gateway device in the Mesh network can be the execution subject of the method provided by the embodiments of the present application. In the case where there are multiple gateway devices in a certain physical space, the multiple gateway devices cooperate to uniformly manage the network topology of the node devices under the entire physical space. For this purpose, the gateway device needs to obtain the first network information between each of the multiple gateway devices in the Mesh network and its surrounding node devices, so that each gateway device obtains the first network information between all gateway devices and their surrounding node devices.

[0094] Each gateway device can sense the network information of its surrounding node devices and use this network information as the first network information between the gateway device and the surrounding node devices. The first network information includes at least one of the following information: the first connection state between the node device and the gateway device, the relay hop count between the node device and the gateway device, the signal strength of the node device with respect to the gateway device, the proxy channel construction state between the node device and the gateway device, and the first data transmission delay between the node device and the gateway device. The first connection state can be connected or not connected. The proxy channel construction state refers to whether the node device is a proxy node. If the node device is a proxy node, a proxy channel is established between the gateway device and the node device, and the communication rate between the two is faster. The first data transmission delay (RTT value) can be the time interval from when the gateway device initiates a query to when it receives a response from the specified node device, specifically, it can be the average RTT value, the maximum RTT value, etc.

[0095] As Figure 4 shown, each gateway device obtains the first network information between all gateway devices and their surrounding node devices. The specific first network information is as follows. Figure 2 In the Mesh network, the relay hop count between the central control and the node devices T7, T10, T14 - T17, D11, D13 - D21 is one hop, the relay hop count between the central control and T4, T5, T8 - T9, T11 - T13, T18 - T22 is two hops, and the relay hop count between the central control and T1 - T3, T6, T23, and T24 is three hops. The relay hop count between central control 1 and the node devices T3, T5 - T7, D1 - D6, D11 is one hop, and so on. It can be seen that the first network information between all gateway devices in the Mesh network and the node devices respectively includes the network information between each gateway device and each node device.

[0096] In one example, step S101 can be implemented in the following manner: The gateway device obtains the first network information of its surrounding node devices and provides this first network information to other gateway devices in the mesh network; and, the gateway device receives the first network information provided by other gateway devices. Specifically, when the gateway device senses that the first network information of its surrounding node devices has changed, it synchronizes this network information to other gateway devices.

[0097] Step S103: Obtain the first target data.

[0098] The first target data can be data that the gateway device wants to send to the node device, such as a control instruction or configuration data, etc.

[0099] The first target data can also be the first target data sent by the server to the target node device. In this case, step S103 can be implemented in the following manner: Receive the first target data sent by the server to the target node device. Taking the server as the IoT cloud platform as an example, the gateway device can receive device control instructions or device configuration data, etc., sent by the IoT cloud platform to the smart devices in the user's home as the first target data.

[0100] Step S105: Select a first target gateway device from the multiple gateway devices according to the first network information, so as to send the first target data to the target node device through the first target gateway device.

[0101] When the gateway device obtains the first target data, it may not directly send this data, but instead, in combination with the first network information of its surrounding node devices maintained by all gateway devices, select a gateway device with a more suitable communication link to the target node device as the first target gateway device. For example Figure 5 as shown, if the gateway device that executes the method provided in the embodiment of the present application selects itself and finds that it is not a more suitable gateway device for sending the first target data, it will not send the first target data into the air, thereby making the processing of the first target data by the gateway device more efficient.

[0102] In one example, the first network information includes at least one of the following information: the first connection state between the node device and the gateway device, the relay hop count between the node device and the gateway device, the signal strength of the node device with respect to the gateway device; step S105 may include at least one of the following processes: Select the gateway device connected to the target node device according to the first connection state; Select the gateway device that meets the relay hop count condition with the target node device according to the relay hop count; Select the gateway device that meets the signal strength condition with the target node device according to the signal strength.

[0103] The first network information includes: the first connection status between the node device and the gateway device; step S105 may include the following processing: according to the first connection status, select the gateway device connected to the target node device. Adopting this processing method enables checking the online or offline status of the peripheral node devices of the gateway device. Online (connected to this gateway device) indicates that normal communication can be established between the gateway device and the target node device, and offline (not connected to this gateway device) indicates that normal communication cannot be established. Gateway devices detected with the target node device being "offline" can be excluded.

[0104] The first network information includes: the relay hop count between the node device and the gateway device; step S105 may include the following processing: according to the relay hop count, select the gateway device that meets the relay hop count condition with the target node device. The relay hop count condition may be that the relay hop count is less than the hop count threshold. The fewer the relay hop counts, the fewer relays the gateway device needs to pass through to reach the target node device, and the shorter the distance. Adopting this processing method can exclude gateway devices that do not meet the relay hop count condition, such as excluding gateway devices with a larger hop count.

[0105] The first network information includes: the signal strength of the node device with respect to the gateway device; step S105 may include the following processing: according to the signal strength, select the gateway device that meets the signal strength condition with the target node device. The signal strength condition may be that the signal strength is less than the signal strength threshold. Adopting this processing method can exclude gateway devices with a smaller detected signal strength of the target node device. For example, if there are multiple gateway devices that are one hop away from the target node device, then exclude the gateway devices with a smaller detected signal strength of the target node device.

[0106] In another example, the first network information may include: the proxy channel construction status of the node device; step S105 may include the following processing: according to the proxy channel construction status, select the gateway device that has established a proxy channel with the target node device. Adopting this processing method can select the gateway device that has established a proxy channel with the target node device. For example, if there are multiple gateway devices that are one hop away from the target node device and have good signal strength, the gateway device that has established a Proxy proxy channel with the target node device can be selected, and the communication rate between this gateway device and the target node device is faster.

[0107] In yet another example, the first network information may include: the first data transmission delay (RTT) between the node device and the gateway device; step S105 may include the following processing: according to the first data transmission delay, select a gateway device that meets the data transmission delay condition with the target node device. The data transmission delay condition may be that the first data transmission delay is less than the delay threshold. By adopting this processing method, a gateway device with a smaller first data transmission delay can be selected. For example, when there are still multiple gateway devices to be selected after the above several processes, the gateway device with a smaller RTT time recorded for communicating with the target node device can be selected according to the RTT time recorded by the gateway device.

[0108] In one example, the method provided by the embodiments of the present application may further include the following steps:

[0109] Step S201: Obtain second network information between each of the multiple gateway devices and the server.

[0110] Each gateway device that executes the method provided by the embodiments of the present application can obtain the network information between itself and the server, and use this network information as the second network information between the gateway device and the server. The second network information includes at least one of the following information: the second data transmission delay between the gateway device and the server, the number of consecutive packet losses of the server. The second data transmission delay may be the time interval from when the gateway device initiates a query to when it receives a reply from the server, and specifically may be an average RTT value, a maximum RTT value, etc. In specific implementation, the gateway device can select its idle period and record the second network information by sending ICMP (Internet Control Message Protocol) probe packets to the server.

[0111] In one example, step S201 may be implemented in the following manner: The gateway device obtains the second network information between itself and the server, and provides the second network information between itself and the server to other gateway devices in the grid network; receives the second network information between other gateway devices and the server provided by other gateway devices. In specific implementation, after the gateway device learns that the second network information between itself and the server has changed, it synchronizes this network information to other gateway devices.

[0112] Step S203: Select a second target gateway device from the multiple gateway devices according to the second network information, so as to communicate with the server through the second target gateway device.

[0113] When the gateway device communicates with the server, it can combine the second network information between each gateway device and the server respectively, and select a gateway device with a better communication link with the server as the second target gateway device. For example,Figure 6 As shown, if it is found that itself is not a better gateway device for communicating with the server, it will not communicate with the server, thereby making the communication between the gateway device and the server more optimized.

[0114] In one example, the second network information includes at least one of the following information: the second data transmission delay between the server and the gateway device, the number of consecutive packet losses of the server; step S203 may include at least one of the following processes: according to the second data transmission delay, select a gateway device that meets the data transmission delay condition with the server; according to the number of consecutive packet losses, select a gateway device that meets the number of consecutive packet loss conditions with the server.

[0115] The second network information includes: the second data transmission delay between the server and the gateway device; step S203 may include the following process: according to the second data transmission delay, select a gateway device that meets the data transmission delay condition with the server. The data transmission delay condition may be that the second data transmission delay is less than the delay threshold, for example, the delay threshold is 200 milliseconds. By adopting this processing method, a gateway device with a smaller second data transmission delay can be selected.

[0116] The second network information includes: the number of consecutive packet losses of the server; step S203 may include the following process: according to the number of consecutive packet losses of the server, select a gateway device that meets the number of consecutive packet loss conditions with the server. The number of consecutive packet loss conditions may be that the number of consecutive packet losses is less than the number threshold, for example, the number threshold is 3 times. By adopting this processing method, a gateway device with a smaller number of consecutive packet losses can be selected.

[0117] In one example, step S103 may be implemented in the following manner: through the second target gateway device, receive the first target data sent by the server to the target node device. As Figure 6 shown, by adopting this processing method, the second target gateway device obtains the first target data from the server, avoiding all gateway devices from obtaining the first target data from the server; therefore, the data communication cost can be effectively reduced, and the processing cost of the gateway device can be reduced.

[0118] In one example, the method provided by the embodiments of the present application may further include the following steps: receiving second target data sent by the node device to the server. Correspondingly, in step S203, communicating with the server through the second target gateway device may be implemented in the following manner: sending the second target data to the server through the second target gateway device. By adopting this processing method, when the gateway device receives the second target data from the node device, it will not directly send the second target data to the server, but will comprehensively consider the second network information of all gateway devices, select a second gateway device with a better link to the server, and report the second target data to the server by the gateway device with a better link.

[0119] As can be seen from the above embodiments, the grid network topology management method provided by the embodiments of the present application is used for gateway devices in a grid network.
