[0036] The present application will be described based on embodiments below, but the present application is not limited to these embodiments. In the following detailed description of the present application, some specific details are described in detail. Those skilled in the art can fully understand the present application without the description of these details. In order to avoid obscuring the essence of the present application, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0037] In addition, those of ordinary skill in the art should understand that the drawings provided herein are for illustrative purposes only, and the drawings are not necessarily drawn to scale.

[0038] Unless the context clearly requires otherwise, the words "including", "comprising", and the like throughout the application should be construed in an inclusive sense rather than an exclusive or exhaustive sense; that is, the meaning of "including but not limited to".

[0039] In the description of the present application, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In addition, in the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0040] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present application are all information and data that have been authorized by the user or fully authorized by all parties. And the collection, use, and processing of relevant data need to comply with the relevant laws, regulations, and standards of relevant countries and regions, and corresponding operation entrances are provided for users to choose to authorize or refuse.

[0041] Traditional wireless local area network technologies, such as WiFi (Wireless Fidelity), rely on centralized network infrastructure, such as base stations, routers, optical fibers, etc. However, the deployment cost of network infrastructure is relatively high, so the number is usually small, and the network infrastructure is usually set at fixed locations. If the device is too far from the network infrastructure or the signal is blocked, it cannot access the Internet, resulting in limited coverage of the Internet in some areas where network infrastructure is difficult to cover, such as remote areas and complex environments. The mesh network, such as the wireless mesh network, is a decentralized organizational structure. Nodes (i.e., devices) accessing the same wireless mesh network can communicate directly without relying on a central node. Moreover, the wireless mesh network supports multi-hop transmission, and data can be relayed through multiple nodes. At the same time, the wireless mesh network has self-organizing capabilities. Devices can automatically discover and join the wireless mesh network and access the Internet through the gateway accessing the wireless mesh network. This enables devices to complete data transmission and access the Internet through multi-hop transmission even without deploying a large number of network infrastructures. Therefore, the wireless mesh network can improve the coverage of the Internet at a relatively low infrastructure deployment cost. The embodiments of the present invention mainly describe the mesh network as an example of the wireless mesh network. It should be understood that the present embodiments are not limited thereto. Existing mesh networks that can support corresponding functions, such as wireless sensor networks (WSN, Wireless Sensor Networks), mobile ad-hoc networks (MANET, Mobile Ad-Hoc Network), etc., or storage devices that can support corresponding functions with the development of future technologies are all within the protection scope of the embodiments of the present invention.

[0042] The gateway can communicate with other nodes in the mesh network through local communication protocols such as Zigbee, Bluetooth, and Z-Wave (wireless networking grid), and communicate with the server or cloud through Internet access protocols such as WiFi and cellular networks. Taking the Bluetooth gateway as an example, the Bluetooth gateway can support both the WiFi protocol and the Bluetooth mesh network protocol simultaneously. However, the working frequency bands of both Bluetooth and WiFi are 2.4 GHz. If Bluetooth and WiFi work simultaneously, it is easy to cause frequency band conflicts. Therefore, to avoid this situation, some Bluetooth gateways use a time-division multiplexing method to switch the communication method, that is, the Bluetooth gateway can only select the Bluetooth mesh network protocol or the WiFi protocol for communication within the same time period. However, time-division multiplexing will cause the Bluetooth gateway to be unable to receive or send data (or data packets) through the mesh network protocol when using the WiFi protocol. If the scanning duty cycle of the Bluetooth gateway, that is, the ratio of the actual scanning time to the total time, is relatively low, the Bluetooth gateway cannot receive the data (or data packets) sent by other nodes in the mesh network during the working period of WiFi. At the same time, factors such as electromagnetic interference, relay node failures, and network congestion may also cause the gateway to be unable to receive the data packets sent by other nodes, so it is easy to cause data loss situations.

[0043] To solve the above problems, embodiments of the present invention propose a communication method, a communication system, an electronic device, and a computer-readable storage medium. Figure 1 It is a schematic diagram of the communication system according to an embodiment of the present invention. As Figure 1 shown, the hardware system architecture of the embodiment of the present invention includes at least one gateway and at least one device. Figure 1 Taking gateway 11 and device 12 as examples for illustration. Gateway 11 and device 12 can establish a communication connection through a wireless mesh network.

[0044] The gateway of the embodiment of the present invention supports both local communication protocols and Internet access protocols, and accesses the Internet through the Internet access protocol. Figure 2 It is a schematic diagram of the software layer structure of the gateway according to an embodiment of the present invention. As Figure 2 shown, the software layer of gateway 11 includes a virtual relay module 21, a network layer 22, a transport layer 23, and an application layer 24. Among them, the virtual relay module 21 is mainly used for relaying data packets and ensuring the orderliness of data packets, including sorting and deduplicating the data packets sent by device 12. The network layer 22 is used to ensure the physical connection and basic communication functions of the mesh network, including receiving the data packets of device 12 directly transmitted by the hardware layer ( Figure 2 not shown) or processed and transmitted by the virtual relay module 21. The transport layer 23 is mainly responsible for data routing, ensuring data transmission reliability, traffic control, etc. The application layer 24 is used to be responsible for specific application logics and data processing, including data format conversion, device control, security verification, etc.

[0045] Device 12 is a node in the wireless mesh network and can directly send data packets to the gateway 11 as a source node. At the same time, devices in the wireless mesh network can use communication modes such as broadcast mode and multicast (i.e., groupcast) mode to allow multiple nodes in the mesh network to receive data packets. Therefore, device 12 can also receive data packets sent by other nodes and act as a relay node and / or a cache node to send the received data packets of other nodes to the target node (i.e., gateway 11). When acting as a relay node for at least one device in the wireless mesh network, device 12 can forward the received data packets to gateway 11 after receiving the data packets sent by other devices in the wireless mesh network. When acting as a cache node in the wireless mesh network, device 12 can cache these data packets in the memory after receiving the data packets sent by other devices in the wireless mesh network and actively send these data packets to gateway 11, or can send the cached data packets to gateway 11 after receiving a data transmission instruction sent by gateway 11 for instructing device 12 to send the data packets cached in the memory.

[0046] In an embodiment of the present invention, gateway 11 can receive the to-be-processed data packets cached and sent by device 12 through a local communication protocol, perform deduplication processing on the to-be-processed data packets based on the processed data packets to obtain target data packets, and then process the target data packets. The embodiment of the present invention improves the possibility that the data packets are successfully sent to the gateway by receiving and caching the data packets sent by other nodes in the mesh network, and therefore can effectively alleviate the situation of data loss.

[0047] The following is illustrated by method embodiments. Figure 3 is a flowchart of the communication method according to an embodiment of the present invention. As Figure 3 shown, the method of this embodiment includes the following steps:

[0048] Step S100, receive the to-be-processed data packets through a local communication protocol.

[0049] In this embodiment, the gateway can communicate with each node in the wireless mesh network through a local communication protocol and communicate with a server or the cloud through an Internet access protocol. However, the gateway may fail to successfully receive the data packets sent by other nodes due to various factors. To reduce this situation, at least one node is selected as a cache node in the wireless mesh network, and the data packets received from other nodes are cached through the cache node.

[0050] After the device accesses the wireless mesh network, the gateway can obtain the memory of the device in various ways. For example, the device can report its own memory to the gateway through heartbeat information, or the gateway can send a memory query instruction to the device to obtain the memory of each device. To ensure the data caching ability of the storage node, in this embodiment, the caching node can be determined according to the memory of each node. For example, the device with the top n (n is a predetermined integer greater than or equal to 1) remaining memory sorted in descending order can be determined as the caching node; or the device with a memory capacity higher than the preset memory threshold can be determined as the caching node.

[0051] According to the actual settings, the gateway can also obtain the status information of each device, such as power consumption information, and select the caching node according to the memory and power consumption information of each device. For example, the node with the top n remaining memory sorted in descending order and the bottom m (m is a predetermined integer greater than or equal to 1) power consumption sorted in ascending order can be determined as the caching node; or the device with a remaining memory not less than the preset memory threshold and a power consumption not higher than the preset power consumption threshold can be determined as the caching node. According to the actual settings, the gateway can also obtain the status information of each device through various existing methods, and this embodiment does not limit this.

[0052] Therefore, in this step, the gateway can receive the data packets cached by the caching node of the mesh network during the working period of the local communication protocol. According to the actual settings, if the data transmission policy is that the caching node can actively send the data packets to be processed to the gateway through the local communication protocol, the gateway can directly receive the data packets to be processed; if the data transmission policy is that the caching node is controlled to send the data packets to be processed to the gateway, the gateway can send a data transmission instruction to the caching node so that after receiving the data transmission instruction, the caching node sends the data packets to be processed cached in the memory to the gateway.

[0053] Optionally, the data packets cached by the caching node can include the data packets sent by other nodes as the source node, or can include the data packets sent by the caching node as the source node. That is to say, the caching node can be used as the source node at the same time, and can cache the data packets to be processed while sending the data packets to be processed, so as to reduce the possibility of the gateway receiving the data packets to be processed unsuccessfully.

[0054] Step S200, perform deduplication processing on the data packets to be processed based on the processed data packets to obtain the target data packets.

[0055] The gateway can also receive the data packets sent by other nodes during the working period of the local communication protocol. After receiving the data packets sent by other nodes, the gateway will give priority to processing these data packets. Therefore, in this step, the gateway can perform deduplication processing on the data packets to be processed based on the processed data packets (i.e., the processed data packets) to obtain the target data packets, so as to reduce network redundancy.

[0056] Figure 4 is a flowchart of the communication method according to an embodiment of the present invention. As Figure 4 shown, in an alternative implementation of this embodiment, step S200 may include the following steps:

[0057] Step S210, obtain a first data identifier of the processed data packet.

[0058] To ensure the orderliness of data packets, for any data packet, each node may generate a data identifier of the data packet in an increasing manner according to its own node identifier and the generation order of each data packet generated by the node. For example, the node identifier of a device is Node1, and node Node1 generates 5 data packets. Then, according to the generation order of each data packet, node Node1 may incrementally generate data identifiers of each data packet as (Node1,Data1), (Node1,Data2), (Node1,Data3), (Node1,Data4), and (Node1,Data5). Therefore, in this step, the gateway may extract the corresponding first data identifier from the processed data packets.

[0059] Step S220, obtain a second data identifier of the data packet to be processed.

[0060] In this step, the gateway may also extract the second data identifier of the data packet to be processed from the data packet to be processed. The determination method of the second data identifier may refer to the generation method of the first data identifier, which will not be elaborated here.

[0061] Step S230, determine a target data identifier according to the first data identifier.

[0062] In a wireless mesh network, it is allowed that the same source node can send data packets to the target node through multiple transmission paths. That is, the wireless mesh network may include multiple relay nodes or cache nodes, and these relay nodes and cache nodes can all send data packets sent by the same source node to the gateway, which makes the order in which the data packets arrive at the gateway may be inconsistent with the order in which the source node sends the data packets, and the gateway may receive the same data packet repeatedly. The gateway's processing policy for data packets defaults that the arrival order of the data packets is the same as the sending order of the data packets. Therefore, it will consider the data packet received first as a new data packet and the data packet received later as an old data packet. To avoid the data of the old data packet overwriting the data of the new data packet, resulting in data inconsistency or errors, or wasting the gateway's data processing resources by repeatedly processing the same data packet, the gateway will discard the data packet that arrives later.

[0063] However, this method may cause some new data packets to be misidentified as old data packets and discarded because they arrive at the gateway later than the old data packets. Therefore, to avoid the above situation, in this step, the gateway can determine the target data identifier from the second data identifiers of the to-be-processed data packets according to the first data identifier of each processed data packet, so as to determine the to-be-processed data packets that need to be discarded according to the target data identifier.

[0064] After the gateway processes the data of the data packets, it usually only retains the data identifier of the most recently processed data packet. Therefore, in this embodiment, the first data identifier can be the data identifier of the most recently processed data packet. Further, the gateway can compare the first data identifier of the processed data packets corresponding to the same source node with the second data identifiers of each to-be-processed data packet. If the second data identifier is less than the first data identifier, it means that the to-be-processed data packet is an old data packet, so the second data identifier of the to-be-processed data packet can be determined as the target data identifier; if the second data identifier is equal to the first data identifier, it means that the to-be-processed data packet and the processed data packet are the same data packet, so the second data identifier of the to-be-processed data packet can also be determined as the target data identifier.

[0065] For example, the processed data packet that the gateway has most recently processed is the data packet sent by node Node2 with a first data identifier of 3. The gateway can compare the first data identifier with the second data identifiers of the to-be-processed data packets received from node Node2, that is, 1, 2, 5, and 7 respectively, and determine that 1 and 2 are the second data identifiers less than the first data identifier. Therefore, the gateway can determine 1 and 2 as the target data identifiers.

[0066] Step S240, determine the target data packets according to the target data identifier.

[0067] After determining the target data identifier, the gateway can discard the to-be-processed data packets corresponding to the target data identifier, and determine the remaining to-be-processed data packets, that is, the to-be-processed data packets that are not discarded, as the target data packets.

[0068] Step S300, perform data processing on the target data packets.

[0069] After determining the target data packets, the gateway can perform corresponding data processing on each target data packet. In the embodiment of the present invention, by means of caching nodes cooperating to receive data packets sent by other nodes, the gateway can receive at least some data packets that could not be received originally due to factors such as channel conflict and electromagnetic interference. Therefore, it can effectively increase the possibility that the data packets are successfully sent to the gateway, thereby alleviating the situation of data loss.

[0070] Taking the application scenario of the gateway time-division multiplexing switching communication mode as an example, during the period when the gateway communicates through the Internet access protocol, the cache node can still receive the data packets sent by other nodes in the mesh network through the local communication protocol, and during the period when the gateway communicates through the local communication protocol, send the received data packets to the gateway. Therefore, it can effectively alleviate the situation of data loss caused by the gateway being unable to receive the data packets sent by other nodes in the mesh network through the local communication protocol during the period of communicating through the Internet access protocol.

[0071] The gateway in the embodiment of the present invention supports the local communication protocol and the Internet access protocol, and can receive the to-be-processed data packets cached and sent by the cache device in the mesh network through the local communication protocol. After receiving the to-be-processed data packets, the gateway performs deduplication processing on the to-be-processed data packets sent by the cache device according to the processed data packets to obtain the target data packets, and then performs data processing on the target data packets. In the embodiment of the present invention, by means of the cache node receiving and caching the data packets sent by other nodes in the mesh network, the possibility of the data packets being successfully sent to the gateway is increased, so the situation of data loss can be effectively alleviated.

[0072] Figure 5 It is a schematic diagram of the communication device in the embodiment of the present invention, applicable to a gateway that supports the local communication protocol and the Internet access protocol.

[0077] The first duplicate removal subunit includes an identifier comparison module and an identifier determination module.

[0078] Among them, the identifier comparison module is used to compare the first data identifier corresponding to the same source node with each second data identifier; the identifier determination module is used to determine the second data identifier less than or equal to the first data identifier as the target data identifier.
