[0031] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0032] It should be noted that the technical solutions described in the embodiments of this application can be combined arbitrarily without conflict.

[0033] In addition, in the embodiments of this application, "first," "second," etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0034] This application provides a message sending method. Figure 1 This is a flowchart illustrating a message sending method according to an embodiment of this application. Figure 1 As shown, the method is applied to a server, and the method includes:

[0035] S101: Obtain messages sent to target node devices in the Bluetooth Mesh network.

[0036] Here, the server retrieves messages sent to target node devices in the Bluetooth Mesh network. These messages can be of different types, such as control messages and query messages. The recipient of the messages is the target node device in the Bluetooth Mesh network, which can be different IoT devices. In practical applications, the messages can be sent by users through applications. After retrieving the messages, the server can select a gateway with high network communication quality in the Bluetooth Mesh network for the target node device, enabling the target node device to successfully receive the messages.

[0037] S102: Determine the target gateway from the first gateway set based on the first hop count set between the target node device and each gateway in the first gateway set in the Bluetooth Mesh network; the first hop count set represents the number of devices through which the target node device sends a message to each gateway in the first gateway set.

[0038] Here, the server can determine the network communication quality of each gateway in the first set of gateways in the Bluetooth Mesh network based on the first hop count between the target node device and each gateway in the first set of gateways. This allows the server to select a gateway with better performance for communication with the target node device. The first hop count represents the number of devices through which a message sent from the target node device to each gateway in the first set of gateways passes. The first hop count determines the length of the transmission path during message transmission, and the length of the transmission path easily affects the wireless network communication quality. Therefore, the first hop count between the target node device and each gateway in the first set of gateways in the Bluetooth Mesh network reflects the wireless network communication quality between the target node device and each gateway. The lower the hop count between the target node device and the gateway device, the better the wireless network communication quality between them. The first hop count can be obtained by statistically analyzing the heartbeat messages sent by the target node device to the gateway device. For example, when a message can be sent directly from node device A to node device B, the corresponding hop count is 1. When a message sent from node device A needs to be forwarded by node device C before reaching node device B, the corresponding hop count is 2. In practical applications, the first gateway set in a Bluetooth Mesh network reports the first hop count between the node device and each gateway in the first gateway set to the server. The server can then determine the hop count between the target node device and each gateway in the first gateway set from the reported first hop count set. The first hop count set can be reported periodically by the first gateway set or it can be reported automatically by the first gateway set. Furthermore, the server can also perform deduplication on the received first hop count set, thereby further improving data processing efficiency.

[0039] In one embodiment, determining the target gateway from the first gateway set based on the first hop count set between the target node device and each gateway in the first gateway set in the Bluetooth Mesh network includes:

[0040] From the first set of gateways, the gateway corresponding to the first hop count with the smallest value in the first hop count set is determined as the target gateway.

[0041] In order to improve the communication success rate between the target gateway and the target node device, when determining the target gateway, the gateway corresponding to the smallest first hop number in the first hop number set can be determined as the target gateway of the target node device, thereby ensuring the best wireless network communication quality between the target node device and the target gateway.

[0042] In one embodiment, determining the gateway corresponding to the first hop count with the smallest value in the first hop count set as the target gateway includes:

[0043] The gateway corresponding to the highest proportion in the first hop count set is determined as the target gateway; the proportion represents the percentage of the smallest first hop count among the first hop counts of each gateway in the first gateway set and the target node device.

[0044] In practical applications, the first hop count set between the target node device and each gateway in the first gateway set is obtained based on the statistics of heartbeat messages received by the gateway from the target node device. Network fluctuations can affect the transmission path between the target node device and the gateway device. Therefore, to more accurately determine the target gateway, the hop count ratio between the target node and the gateway device can be further considered. The hop count ratio reflects the proportion of different hop count values ​​among all heartbeat messages received by the gateway device from the target node device. For example, if the target node device sends 100 heartbeat messages to the gateway device, and 90 of these heartbeat messages are sent directly from the target node device to the gateway device, while 10 heartbeat messages may be forwarded by other node devices once or multiple times before reaching the gateway device, then the proportion of hop count values ​​of 1 is 90%, and the proportion of other hop count values ​​is 10%. Thus, by using the hop count values ​​and the corresponding hop count ratios, the gateway with the best network performance among the multiple gateway devices in the first gateway set can be determined as the target gateway. In practical applications, as long as the target gateway device does not go offline, the gateway device can continuously count the number of heartbeats between the gateway device and the target node device and the corresponding ratio based on the heartbeat messages sent by the target node device. Therefore, the ratio of the number of heartbeats between the target node device and the gateway device may change.

[0045] In one embodiment, before determining the target gateway from the first gateway set based on the first hop count set between the target node device and each gateway in the first gateway set in the Bluetooth Mesh network, the process includes:

[0046] The first gateway set is determined from the second gateway set; the second gateway set represents all gateways in the Bluetooth Mesh network; the first gateway set represents gateways in the Bluetooth Mesh network that are online.

[0047] To improve the efficiency of identifying the target gateway, the selection range can be further narrowed down by limiting the first gateway set to online gateways in the Bluetooth Mesh network. In practical applications, due to network quality limitations, gateways in the Bluetooth Mesh network may be online or offline. When a gateway in the Bluetooth Mesh network is online, it can achieve wireless network communication with the target node device. When a gateway in the Bluetooth Mesh network is offline, it means that the gateway cannot work properly and cannot achieve wireless network communication with the target node device. Therefore, the online gateways can be identified from all gateways in the Bluetooth Mesh network to form the first gateway set. The target gateway for the target node device can then be identified from the first gateway set, thus ensuring that the identified target gateway can communicate normally with the target node device.

[0048] In one embodiment, determining the first gateway set in the second gateway set includes:

[0049] The gateway that reports the first heartbeat message in the second gateway set during the first time interval is determined as the first gateway set.

[0050] Here, when the gateway device in the Bluetooth mesh network is online, it can communicate wirelessly with the server. In other words, the gateway device can transmit data with the server. Therefore, the gateway device can report a first heartbeat message to the server to determine that the current gateway device is online. If the server can receive the first heartbeat message reported by the gateway device in the Bluetooth mesh network within the first time interval, it indicates that the gateway can communicate wirelessly with the server, which means that the gateway device that reported the first heartbeat message is online. Thus, the server can determine that the gateway device is the gateway device of the first set of gateways. For example, the server will determine the gateway device in the Bluetooth mesh network that reported the first heartbeat message as the gateway of the first set within 15 seconds.

[0051] In one embodiment, such as Figure 2 As shown, the method further includes:

[0052] S201: Determine the gateways in the second gateway set that have not reported the first heartbeat message within a set time period as the third gateway set; the third gateway set represents the gateways in the Bluetooth Mesh network that are in a disconnected state.

[0053] Here, when a gateway device in a Bluetooth mesh network is offline, it cannot communicate wirelessly with the server. In other words, the gateway device cannot transmit data with the server, and the server cannot receive the first heartbeat message reported by the gateway device. In practical applications, the server can identify gateway devices in the second gateway set that have not reported a first heartbeat message within a set time period as belonging to the third gateway set that are offline. The set time period is longer than the first time interval. In practice, the first time interval is the period during which a gateway device should report a first heartbeat message. However, gateway devices may temporarily go offline due to network fluctuations. When a gateway device attempts to reconnect, it may successfully reconnect and return to online status. Therefore, by setting a time period longer than the first time interval, the server can avoid incorrectly judging the connection status of gateway devices due to temporary network fluctuations. For example, under normal circumstances, the server receives the first heartbeat message reported by gateway devices in the second gateway set every 15 seconds. If the server has not received the first heartbeat message reported by gateway devices in the second gateway set within 45 seconds, it can determine that the gateway device is currently offline. In practical applications, the set duration can be set to the maximum time to wait for the gateway to reconnect. If the gateway fails to reconnect within this time, it can be considered that the gateway is offline.

[0054] S202: Delete the hop count data between each gateway in the third gateway set and each node device in the Bluetooth Mesh network.

[0055] Here, after determining the third gateway set, the hop count data between each gateway in the third gateway set and each node device in the Bluetooth Mesh network is deleted. In practical applications, since the gateways in the third gateway set are already offline, the server will not consider them as target gateways. Therefore, it is not necessary to obtain the hop count data between each node device in the Bluetooth Mesh network and each gateway in the third gateway set reported to the server by each gateway in the third gateway set before it went offline. This allows for the rapid determination of the first gateway set that is online in the Bluetooth Mesh network.

[0056] S103: Send the message to the target gateway to forward the message to the target node device through the target gateway.

[0057] Here, a message is sent to the target gateway, which can then forward it to the target node device, thus enabling the message to reach the target node device via the shortest transmission path. In practical applications, after receiving the message, the target node device processes it to perform corresponding operations, thereby improving the target node device's message response speed.

[0058] In the above embodiments, the heartbeat data between the target node device and each gateway in the Bluetooth Mesh network can reflect the quality of wireless network communication between the surrounding target node devices and each gateway in the Bluetooth Mesh network. This allows the target node device to dynamically select the target gateway with the best network communication quality, thereby improving the communication quality between the target gateway and the target node device. This optimizes the transmission time required for communication and increases the success rate of communication between the target gateway and the target node device.

[0059] This application also provides another message sending method, such as Figure 3 As shown, the method is applied to a gateway device, and the method includes:

[0060] S301: Determine a second hop count set between each first node device in the first node set of the Bluetooth Mesh network and the gateway device; the second hop count set represents the number of devices that each first node device in the first node set passes through when sending a message to the gateway device.

[0061] Here, the gateway device counts the second hop count between each first node device in the first node set of the Bluetooth Mesh network and the gateway device. The second hop count represents the number of devices that each first node device in the first node set passes through when sending a message to the gateway device. Thus, the length of the transmission path between each first node device in the first node set and the gateway device can be determined by the second hop count. Furthermore, the quality of wireless network communication between each first node device in the first node set and the gateway device can be further determined by the length of the transmission path. In practical applications, the gateway device can receive heartbeat messages sent by each first node device in the first node set. The gateway device determines the second hop count between each first node device and the gateway device by statistically analyzing the heartbeat messages sent by each first node device in the first node set. Specifically, each first node device in the first node set sends a heartbeat message to the gateway device. The heartbeat message can carry parameters, and the second hop count between the first node device and the gateway device can be obtained from the parameters carried in the heartbeat message. For example, if the heartbeat message sent by the first node device carries a parameter of 8, the gateway device will subtract the parameter carried in the heartbeat message after receiving it, obtaining a parameter of 7. The difference between parameter 8 and parameter 7 is 1, so the second hop count between the first node device and the gateway device is 1. In practical applications, the second hop count set can be used to determine the length of the transmission path between each first node device in the first node set and the gateway device. Therefore, the wireless network communication quality between the gateway device and each first node device in the first node set can be determined using the second hop count set. For example, when a message can be sent directly from first node device A to first node device B in the first node set, the second hop count value of the corresponding second hop count set is 1. When a message sent from first node device A in the first node set needs to be forwarded by first node device C in the first node set before reaching first node device B, the second hop count value of the corresponding second hop count set is 2. In practical applications, the lower the second hop count value of the second hop count set, the better the wireless network communication quality between the first node device and the gateway device.

[0062] S302: Report the second hop count set to the server.

[0063] Here, the gateway device reports the second-hop count to the server, enabling the server to determine the wireless network communication quality between the gateway device and the node device based on the reported second-hop count. In practical applications, when new node device information is added, node device information is modified, or network data is updated, the gateway device needs to upload the changed information to the server for updating.

[0064] In one embodiment, the method further includes:

[0065] The gateway device, acting as the target gateway, receives the message sent by the server and sends the message to the target node device; wherein...

[0066] The target gateway is determined based on the set of third hops between the target node device and each gateway in the fourth set of gateways in the Bluetooth Mesh network.

[0067] Here, users send messages through the application. These messages can be of different types, such as control messages and query messages. The recipients of these messages are the target node devices in the Bluetooth Mesh network. The gateway device, acting as the target gateway, receives messages from the server. The target gateway is determined based on the set of third hop counts between the target node device and each gateway in the fourth set of gateways in the Bluetooth Mesh network. In practice, the gateway device with the smallest third hop count in the set can be used as the target gateway. Furthermore, the proportion of the smallest third hop count can be combined to further determine the target gateway within the Bluetooth Mesh network. The target gateway sends messages to the target node device using the shortest communication path, improving message transmission efficiency.

[0068] In one embodiment, such as Figure 4 As shown, the method further includes:

[0069] S401: The node devices in the first node set that did not report the second heartbeat message during the second time interval are determined as the second node set, and the second node set represents the node devices that have abnormal communication with the gateway device.

[0070] Here, the gateway device can periodically receive second heartbeat messages reported by each first node device in the first node set. The gateway device can determine the existence of communication between the first node device and the gateway device based on these second heartbeat messages, and can also determine the second hop count set between the first node devices and the gateway device in the first node set based on the second heartbeat information. Node devices in the first node set that fail to report second heartbeat messages within the second time interval are defined as the second node set. The wireless network communication between the node devices in the second node set and the gateway device is abnormal; the node devices in the second node set cannot receive messages from other node devices, nor can they send messages to other node devices.

[0071] S402: Delete the hop count data between each node device in the second node set and the gateway device.

[0072] Here, due to anomalies in the wireless network communication between the node devices in the second node set and the gateway device, the hop count data between each node device in the second node set and the gateway device can no longer represent the number of devices traversed by the node device when sending a message to the gateway device. Specifically, the hop count data between each node device in the second node set and the gateway device is calculated by the gateway device based on the second heartbeat information previously reported by the node devices in the second node set. Therefore, it is necessary to delete the hop count data between each node device in the second node set and the gateway device. Furthermore, due to the anomalies in the wireless network communication between the node devices in the second node set and the gateway device, the server cannot select a target gateway for the node devices in the second node set. Therefore, the gateway device no longer needs to calculate the hop count data for the node devices in the second node set, further cleaning up the invalid hop count data stored on the gateway device.

[0073] In one embodiment, the method further includes:

[0074] A third heartbeat message is reported to the server according to the third time interval.

[0075] Here, to allow the server to determine the gateway device's connection status, the gateway device reports a third heartbeat message to the server at a third time interval. This third heartbeat message determines the gateway device's connection status. In practical applications, when the gateway device is online, it indicates that it can communicate with the server. Therefore, the gateway device can report a third heartbeat message to the server to confirm its online status. Conversely, when the gateway device is offline, it indicates that it cannot communicate with the server. In this case, the gateway device fails to report a third heartbeat message. When the server does not receive the third heartbeat message reported by the gateway device, it confirms that the gateway device is currently offline. Therefore, the server can determine the current connection status of the gateway device based on the reported third heartbeat message, thus avoiding the server selecting a target gateway for the target node device from among the offline gateway devices.

[0076] In the above embodiments, the gateway device counts the second hop count between each first node device in the first node set and the gateway device, and reports the counted second hop count to the server. This enables the server to dynamically select the best-performing target gateway for communication with the target node device based on the wireless network communication quality between the gateway device and the target node device, thereby improving message sending efficiency.

[0077] To implement the method of the embodiments of this application, the embodiments of this application also provide a message sending device, such as... Figure 5 As shown, the device includes:
