[0048] The embodiment of the present application provides a network access method, which is applied to a gateway device and is used to automatically connect a terminal device to a high-quality gateway device. The method periodically detects a network search request sent by a terminal device, and after detecting the network search request, sends a binding request including a network search request and a first signal strength to a server. Only after receiving a binding response sent by the server based on the binding request, the corresponding terminal device is accessed, and a network search confirmation response is sent to the terminal device, so that when multiple gateway devices receive a network search request from a terminal device, the terminal device is automatically connected to a high-quality gateway device, thereby improving the efficiency of the connection and ensuring the quality of the connection.

[0049] The network access method provided in the embodiment of the present application can be applied to single-module gateway devices, such as Bluetooth mesh gateway, Zigbee gateway, Wi-Fi smart gateway; it can also be applied to multi-module gateway devices that simultaneously support multiple wireless communication technologies such as Bluetooth mesh, Wi-Fi and Zigbee. The embodiment of the present application does not impose any restrictions on the specific type of gateway device.

[0050] like Figure 1 As shown, an embodiment of the present application provides a network access method, which is applied to a gateway device, and the method includes:

[0051] Step S10: When in working state, detecting a network search request once at a first preset time interval.

[0052] In the application, the working state of the gateway device refers to the state of the gateway device after it is powered on; for a gateway device with network communication function, the working state refers to the state after it is powered on and connected to the network.

[0053] In the application, the working state requires that the load level of the gateway device is less than the corresponding maximum workload level.

[0054] In the application, in order to ensure that no matter when the terminal device broadcasts a network search request, it needs to access the gateway device, and the gateway device can detect the network search request broadcast by its terminal device as soon as possible, the first preset time interval between the gateway device detecting a network search request will be as small as possible, which can be selected according to different application scenarios. For example, in the smart home scenario, on the one hand, the terminal device has a more urgent need to access the network, and the terminal device is likely to be in a location covered by the signal of the gateway device, so the terminal device will broadcast the network search request at a higher frequency; on the other hand, new terminal devices are not often connected to the gateway device, so by setting the first preset time interval between each detection of the network search request by the gateway device to a larger time, such as 10 seconds, the network search request can be detected as soon as possible, and without affecting the user experience, the gateway device can be prevented from frequently and ineffectively detecting the broadcast status. In the industrial Internet of Things scenario or the commercial hotel scenario, new terminal devices often join the gateway device, and the performance of the gateway device is relatively strong, so the first preset time can be set to a smaller time, such as 200 milliseconds, so as to detect the network search request in time and perform subsequent network access steps to ensure user experience.

[0055] It is understandable that, by detecting a network access request once at a first preset time interval in a working state, it is possible to automatically trigger the terminal device to connect to a high-quality gateway device, thereby freeing the user.

[0056] Step S11, after detecting a network search request broadcast by a terminal device, sending a binding request to a server, the binding request includes the network search request and a first signal strength, and the network search request includes a unique identifier of the terminal device.

[0057] In the application, in order to ensure the utilization rate of each gateway device, each gateway device will strive to access the terminal device after detecting the network search request broadcast by the terminal device. Therefore, after receiving the network search request, it sends a binding request to the server, requesting the server to bind with the terminal device and access the terminal device. The binding request includes a network search request and a first signal strength. The network search request includes a unique identifier of the terminal device, which uniquely corresponds to the terminal device. Therefore, the network search request broadcast by the same terminal device is the same, and the network search requests broadcast by different terminal devices are different. The server can identify the binding requests sent by multiple gateway devices to bind to the same terminal device according to the network search request. The first signal strength refers to the strength of the signal connection between the terminal device and the gateway device, which can be the signal strength of the terminal device evaluated by the terminal device side, such as the received signal strength indication (RSSI), signal-to-noise ratio (SNR), or link quality indication (LQI) and other signal strength indicators; it can also be the signal strength of the gateway device evaluated by the terminal device side. In the application, the first signal strength can be configured with different signal strength indicators according to different scenarios.

[0058] Step S12, after receiving the binding response sent by the server based on the binding request, access the corresponding terminal device according to the binding response, and send a network search confirmation response to the corresponding terminal device, the binding response including the binding relationship between the gateway device and the terminal device.

[0059] In the application, if multiple gateway devices detect the network search message broadcast by the same terminal device, then the multiple gateway devices will send binding requests to the server, requesting to bind and access the terminal device. The server will bind a unique target gateway device for the terminal device based on the first signal strength and the load level of each gateway device, and send a binding response to the target gateway device. The target gateway device accesses the corresponding terminal device according to the binding relationship between the target gateway device and the terminal device in the binding response.

[0060] In one embodiment, the method further comprises:

[0061] After accessing the terminal device, update the terminal device list;

[0062] The load level is updated according to the terminal device list.

[0063] In the application, after accessing the terminal device, the gateway device adds the unique identifier of the terminal device to the terminal device list and marks it as online; then the load level is updated according to the terminal device list, and the load level is positively correlated with the number of terminal devices in the online state.

[0064] In the application, the gateway device can update the terminal device's online or offline status according to the heartbeat data. If the heartbeat data sent by the terminal device that has been connected to the network is received, the terminal device is marked as online according to the heartbeat data; if the heartbeat data sent by the terminal device that has been connected to the network is not received within the preset heartbeat time, the terminal device is marked as offline.

[0065] In the application, the load level of the gateway device can also be updated according to the occupation of communication resources by each terminal device in an online state, or the type identification of the terminal device can be received to determine the type of the terminal device, and then the occupation of communication resources by the terminal device is estimated, and then the load level is updated. It can be understood that when calculating the load level of the gateway device, the occupation of communication resources by different types of terminal devices is estimated to achieve a more accurate load level assessment, so as to more accurately bind a higher quality gateway device to the terminal device.

[0066] The embodiment of the present application also provides a network access method, which is applied to a terminal device and is used to automatically access a high-quality gateway device. The method broadcasts a network search request to n gateway devices once every second preset time when in a non-binding state, thereby accessing a target gateway device that meets the preset conditions among the n gateway devices, and then enters a binding state after receiving a network search confirmation response sent by the target gateway device, thereby automatically accessing a high-quality gateway device.

[0067] In the application, the terminal device can be a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA) and other mobile devices, or it can be a smart playback device, a television, a smart refrigerator, a smart lighting device, a smart switch, a home monitoring and other smart home devices. The method provided in the embodiment of the present application does not impose any restrictions on the type of terminal device.

[0068] like Figure 2 As shown, an embodiment of the present application provides a network access method, which is applied to a terminal device, and the method includes:

[0069] Step S20: in the unbound state, broadcast a network search request to n gateway devices once every second preset time, where n is a positive integer.

[0070] In the application, the unbound state means that the terminal device is not connected to the gateway device, for example, the terminal device is powered on for the first time or the gateway device connected to the terminal device is offline or faulty. After powering on or after losing connection with the gateway device, the terminal device can broadcast a network search request to n gateway devices every second preset time interval to request access to the gateway device.

[0071] In the application, the network search request includes a unique identifier of the terminal device, which is used to uniquely correspond to the terminal device, so that the corresponding terminal device can be uniquely determined according to the network search request.

[0072] In the application, there may be one or more gateway devices. The second preset time may be a shorter time, such as 1 second, to achieve faster access to the gateway device; the second preset time may also be dynamically changed. After the first broadcast of the network search request, if no network search confirmation response is received for a long time, the second preset time is gradually extended.

[0073] Step S21, receiving a network search confirmation response sent by a target gateway device and entering a binding state, wherein the target gateway device is a gateway device among the n gateway devices that meets a preset condition with the terminal device.

[0074] In the application, after receiving the network search request, the gateway device will send a binding request to the server. The binding request includes the network search request and the first signal strength. The first signal strength refers to the signal strength between the gateway device and the terminal device. The server will automatically add the terminal device to the high-quality gateway device based on the signal strength in the binding request and the load level of the gateway device. After adding the terminal device, the gateway device will send a network search confirmation response to the terminal device. The terminal device can determine that it has joined the gateway device based on the network search confirmation response, and then enter the binding state and stop sending network search requests.

[0075] In one embodiment, the method further comprises:

[0076] Step S22: If the signal quality of the bound gateway device is less than the target signal quality or stops working, it enters the unbound state.

[0077] In applications, signal quality includes signal strength, network status, communication rate, etc. In applications, some terminal devices have higher requirements for communication, so they need higher signal strength. Therefore, when the signal quality of the bound gateway device is lower than the target signal quality, such as when the network delay is high and the network rate is slow, there is a need to access a higher quality gateway. By entering the unbound state, the network search request is automatically sent to complete the switching of the gateway device. For example, in a hotel scenario, when the quality of the gateway connected to the smart door lock in the room deteriorates or fails, the door lock will automatically switch to a gateway with better quality to ensure the timeliness and availability of the door lock.

[0078] The embodiment of the present application provides a network access method, which is applied to a server device and is used to automatically connect a terminal device to a high-quality gateway device. The method receives a binding request sent by a gateway device and obtains the load level of each gateway device. Based on the first signal strength in each binding request and the load level of the gateway device corresponding to each binding request, the method selects a target gateway device for each terminal device corresponding to the network search request, and sends a binding response to the target gateway device, thereby automatically connecting the terminal device to a high-quality gateway device, improving the connection efficiency and ensuring the connection quality.

[0079] like Figure 3 As shown, an embodiment of the present application provides a network access method, which is applied to a server, and the method includes:

[0080] Step S30: receiving a binding request sent by a gateway device, wherein the binding request includes a network search request broadcast by the terminal device and a first signal strength, and the network search request includes a unique identifier of the terminal device.

[0081] Step S31, obtaining the load level of each gateway device.

[0082] In the application, since each gateway device accesses the terminal device through the server, the server can evaluate the load of the gateway device according to the number of terminal devices accessed by the gateway device each time.

[0083] In the application, the load degree of the gateway device can also estimate the occupancy of the communication resources by the terminal device according to the type identification of the terminal device connected to it, and evaluate the load degree of the gateway device based on the estimated occupancy. It can be understood that the load degree of the gateway device can be more accurately evaluated by combining the number of terminal devices connected to the gateway device and the estimated occupancy of the communication resources based on the type identification of the terminal device.

[0084] In the application, the load level of the gateway device can also be obtained in real time.

[0085] Step S32, when multiple binding requests include the same network search request, based on the first signal strength in each binding request in the multiple binding requests and the load level of the gateway device corresponding to each binding request, select a target gateway device for the terminal device corresponding to the network search request.

[0086] In the application, if multiple gateway devices detect the network search message broadcast by the same terminal device, then multiple gateway devices will send binding requests to the server, requesting to bind and access the terminal device. The server will combine the first signal strength and the load level of each gateway device to bind the terminal device to the target gateway device with the highest overall quality.

[0087] Step S33: Send a binding response to the target gateway device, wherein the binding response includes a binding relationship between the target gateway device and the terminal device corresponding to the network search request.

[0088] In the application, the target gateway device accesses the corresponding terminal device according to the binding relationship between the target gateway device and the terminal device in the binding response.

[0089] It can be understood that the method provided by the embodiment of the present application can achieve load balancing of various gateway devices.

[0090] In one embodiment, selecting a target gateway device for the terminal device corresponding to the network search request based on the first signal strength in each binding request in the multiple binding requests and the load level of the gateway device corresponding to each binding request includes:

[0091] If the first signal strength in the binding request is greater than the preset signal strength, and the load level of the gateway device corresponding to the binding request is less than the preset load level, the gateway device corresponding to the binding request is set as the target gateway device of the terminal device corresponding to the network search request.

[0092] In applications, the preset signal strength can be determined according to the type of terminal device, and different terminal devices have different requirements for signal strength; the preset load level can be determined according to the type of terminal device, and different terminal devices have different requirements for bandwidth, delay, etc.

[0093] In the application, one or more gateway devices can be first selected based on the first signal strength and the preset signal strength in each binding request, and then the target gateway device can be selected based on the load level and the preset load level of each gateway device. For example, the gateway devices with the first signal strength in the top 30% are selected first, and then the gateway device with the smallest load level among the 30% of gateway devices is selected. It can be understood that the above method can bind the gateway device with the highest comprehensive quality to the terminal device.

[0094] In one embodiment, the network search request further includes a type identifier of a terminal device corresponding to the network search request;

[0095] The preset signal strength and the preset load level are set according to the type identifier of the terminal device corresponding to the network search request.

[0096] In the application, the communication quality requirements of the terminal device, such as bandwidth, delay, etc., can be queried according to the type identifier, and then the preset signal strength and preset load level can be set.

[0097] In one embodiment, after sending the binding response to the target gateway device, the method further includes:

[0098] The load level of the target gateway device is updated.

[0099] In the application, each time a terminal device is connected, the load level of the gateway device will change. Therefore, the load level needs to be updated in time to provide accurate data support for the subsequent server to bind the terminal device to the gateway device. Specifically, the load level can be updated according to the number of terminal devices connected to the gateway device, or according to the type of the newly connected terminal device, its occupancy of the communication resources of the gateway device can be estimated, and then the load level can be updated according to the estimated occupancy.

[0100] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
