Detailed Description
In order to make the purpose, technical solution and effect of the present application clearer and clearer, the present application is further described in detail below with reference to the accompanying drawings and examples.
Different from the prior art, the application provides a network connection method, which includes that after receiving a private broadcast message of a device to be accessed, a first network node device judges whether other network node devices which start network proxy service exist in the same network, and the first network node device compares the intensity of received signals with other network node devices, and the network node device with higher intensity of received signals starts the network proxy service and is connected with the device to be accessed. The network connection method is suitable for various network connection types, and is not limited herein. For convenience of description only, the Mesh network is taken as an example for detailed description. As can be seen by those skilled in the art, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems in other application scenarios without creative efforts.
Referring to fig. 1, fig. 1 is a flowchart illustrating a network connection method according to an embodiment of the present application. It should be noted that, if the result is substantially the same, the flow sequence shown in fig. 1 is not limited in this embodiment. As shown in fig. 1, the method includes:
step 110: the first network node device receives a private broadcast message of a device to be accessed.
One or more network node devices may be included in a mesh network, each of which may receive and transmit broadcast messages. Each network node device in the mesh network communicates by broadcast. For example, the communication channel in the mesh network may include 37, 38, or 39, etc. The network node devices in the same mesh network can receive the messages of the same mesh network and can also receive the broadcast messages of other devices (devices to be accessed).
The device to be accessed is a device to be connected with the network where the first network node device is located. The device to be accessed can be a mobile terminal, a router or a remote controller and the like; it may also refer to an Application (APP) installed on the device. The device to be accessed is a Bluetooth device and can send broadcast messages on a broadcast channel at fixed intervals. The broadcast message includes a Length value (Length), a broadcast Type (Advertising Type), broadcast Data (Advertising Data), and the like. The message broadcasted by the device to be accessed may be received by the first network node device and other network node devices in the same network as the first network node device. The private broadcast message sent by the device to be accessed is a non-connectable message, that is, the device to be accessed sends the private broadcast message only to notify the network node device to start the network proxy service, and the network node device which receives the private broadcast message is not required to be connected with the device to be accessed.
Step 120: if the second network node equipment starts the network proxy service in the same network, the first network node equipment compares the received signal strength of the first network node equipment with the received signal strength of the second network node equipment, so that the network node equipment with higher received signal strength starts the network proxy service, and the equipment to be accessed is connected to the network node equipment which starts the network proxy service.
When the first network node device identifies that a second network node device which has started the network proxy service still exists in the same network, the first network node device may acquire the received signal strength of the second network node device. The first network node device can compare the received signal strength of the second network node device with its own received signal strength to determine the network node device with the greater received signal strength. When the network node device starts the network proxy service, the device to be accessed can scan and connect with the network node device. The received signal strength refers to the strength of a signal of a device to be accessed, which is received by the network node device.
One or more second network node devices for starting the network proxy service in the same network can be used, and after the received signal strength comparison is carried out, the network node device with higher received signal strength starts the network proxy service to be connected with the device to be accessed.
The embodiment of the application determines the network node equipment with higher received signal strength by comparing the received signal strength between different network node equipment; and the network node equipment with higher received signal strength starts proxy service to be connected with the equipment to be accessed. Therefore, the proxy service equipment connected with the equipment to be accessed can be ensured to receive stronger signals, and the network and the equipment to be accessed can be ensured to have better communication quality.
Referring to fig. 2, fig. 2 is a flowchart illustrating a network connection method according to another embodiment of the present application. It should be noted that, if the result is substantially the same, the flow sequence shown in fig. 2 is not limited in this embodiment. As shown in fig. 2, the method includes:
step 210: a broadcast message is received.
In an embodiment, the first network node device is in a listening state and is capable of receiving broadcast messages. The first node device can receive other types of broadcast messages of other devices besides the private broadcast message of the device to be accessed. Similarly, other network node devices in the same network as the first network node device are also in the listening state, and can receive the broadcast message.
Step 220: and judging whether the private identification information in the private broadcast message is at least partially identical to the private identification information of the first network node equipment.
If yes, go to step 230, if no, return to step 210.
In an embodiment, the format of the private broadcast message is as shown in fig. 3, and the private broadcast message includes: length of data (Length), broadcast Type (Advertising Type), private broadcast data, etc. Wherein the private broadcast data includes: private identification information, device Type, Action Type (Action Type), etc. Private identification information refers to data including information customized by a manufacturer of a device, such as a manufacturer ID or a device ID. The device manufacturer may refer to a manufacturer of the device to be accessed, or may also refer to a manufacturer of an app of the device to be accessed.
Take the format of the private broadcast message shown in fig. 3 as an example, where the broadcast type is OxFF, the device type is APP, the private identification information is the manufacturer ID of the APP, and the action type is to open the network proxy service. At this time, the private broadcast message indicates that the APP is about to connect, and all network node devices receiving the broadcast message may choose to start the network proxy service.
When the private identification information of the device to be accessed in the broadcast message is judged to be at least partially the same as the private identification information of the first network node device, for example, the vendor ID is the same, the network node device performs the subsequent steps. Otherwise, the broadcast message is ignored and monitoring is continued.
In one embodiment, the private broadcast message includes private identification information of the device to be accessed; the private identification information of the device to be accessed is at least partially the same as the private identification information of the first network node device. That is, the first network node device can perform network connection only if it needs to determine that the devices to be accessed are devices of the same manufacturer. By determining whether the private identification information is the same, it can be determined whether the device to be accessed needs to access the network. Under the condition that a plurality of networks exist simultaneously, the connection error of the equipment to be accessed can be avoided.
Step 230: and judging whether a second network node device exists in the same network or not to start the network proxy service.
If yes, go to step 240; if not, go to step 250.
After the network proxy service is started, the network node device sends a connection broadcast message for notifying the device to be accessed to establish connection. Meanwhile, other network node devices in the same network as the network node device can also receive the connection broadcast message sent by the network node device.
In an embodiment, a first network node device determines whether a connection broadcast message sent by a second network node device is received; if yes, second network node equipment exists in the same network to start the network proxy service; if not, the second network node equipment does not exist in the same network to start the network proxy service. The connection broadcast message is sent by the second network node device after the network proxy service is started. The first network node device can determine whether other second network node devices starting the network proxy service exist in the same network only by judging whether the connection broadcast message is received or not. Therefore, after the network node device starts the network proxy service, the network node device can inform other network node devices in the same network of the proxy condition of the network node device without sending other broadcast messages.
For more details of the network connection method when a second network node device exists in the same network, please refer to fig. 4 and its related description.
Step 240: and judging whether the received signal strength of the self is greater than the received signal strength of the second network node equipment.
If yes, go to step 250; if not, go to step 260.
In an embodiment, the first network node device may determine its own received signal strength upon receiving a private broadcast message of the device to be accessed. Specifically, the received signal strength includes: at least one of a Reference Signal Received Power (RSRP), a Received Signal Strength Indicator (RSSI), a Reference Signal Received Quality (RSRQ), a signal to interference and noise ratio (SINR), or a signal to noise ratio (SNR).
In an embodiment, the connection broadcast message sent by the second network node device comprises a received signal strength of the second network node device. The first network node device is thus able to compare its own received signal strength with the received signal strength of the second network node device.
Step 250: and starting the network proxy service.
In an embodiment, if there is no second network node device in the same network to start the network proxy service, the first network node device starts the network proxy service and sends a connection broadcast message. That is, the first network node device may directly start the network proxy service when determining that there is no second network node device that has already started the network proxy service in the same network.
In another embodiment, if the received signal strength of the first network node device is greater than the received signal strength of the second network node device, the first network node device opens the network proxy service and notifies the second network node device to close the network proxy service.
After the network proxy service is started, the first network node device sends a connection broadcast message for notifying the device to be accessed to establish connection. Meanwhile, the connection broadcast message sent by the first network node device includes the received signal strength of the first network node device.
Step 260: the network proxy service is not turned on.
In an embodiment, if the received signal strength of the first network node device is less than or equal to the received signal strength of the second network node device, the first network node device does not start the network proxy service. That is, when the first network node apparatus determines that it is not the network node apparatus having the largest received signal strength in the network, the first network node apparatus section turns on the network proxy service.
Referring to fig. 4, fig. 4 is a flowchart illustrating a network connection method according to another embodiment of the present application. It should be noted that, if the result is substantially the same, the flow sequence shown in fig. 4 is not limited in this embodiment. As shown in fig. 4, the method includes:
step 410: and the equipment to be accessed sends a private broadcast message.
The device to be accessed can be referred to as a mobile terminal or an APP installed on the mobile terminal. And the equipment to be accessed sends the broadcast message according to fixed interval time in a preset time period. The device to be accessed sends a private broadcast message for informing the network node device to start the network proxy service. The device to be accessed sends a private broadcast message on a predetermined broadcast channel so that a network node device in the network to be accessed can receive the broadcast message.
Step 420: and starting the network proxy service.
In an embodiment, after receiving the private broadcast message, the second network node device determines that no other network node device in the same network has started the network proxy service, and the second network node device starts the network proxy service. The second network node device further needs to determine that the private identification information of the device to be accessed in the private broadcast message sent by the device to be accessed is at least partially the same as the private identification information of the second network node device. For example, the second network node device needs to determine that the device to be accessed is the same manufacturer as it.
Step 430: the second network node device sends a connection broadcast message.
In an embodiment, the second network node device sends the connection broadcast message after starting the network proxy service. The connection broadcast message is used for informing the device to be accessed to carry out connection. As shown in fig. 5: the format of the connection broadcast message includes: length of data (Length), broadcast Type (Advertising Type), private broadcast data, etc. Wherein the private broadcast data includes: private identification information, device type, received signal strength, etc. Private identification information refers to data including information customized by a manufacturer of a device, such as a manufacturer ID or a device ID. For example, in the connection broadcast message sent by the second network node device, the broadcast type is OxFF, the device type is a network node device, and the received signal strength is the received signal strength of the second network node device.
The second network node device is in the same broadcast channel as other network node devices of the same network. Thus, the connection broadcast message sent by the second network node device may be received by other network node devices in the same network.
Step 440: the received signal strength of the first network node device is compared to the received signal strength of the second network node device.
After receiving the private broadcast message, the first network node device determines whether the device to be accessed, which sends the private broadcast message, is the same manufacturer as the device to be accessed. Thereafter, the first network node device determines whether a connection broadcast message is received. In the event that it is determined that a connection broadcast message is received, the first network node device may determine that a second network node device is present in the same network.
In an embodiment, the first network node device may determine its own received signal strength upon receiving the private broadcast message. When the first network node device receives the connection broadcast message, the first network node device may parse the received signal strength data in the connection broadcast message, thereby obtaining the received signal strength of the second network node device.
In one embodiment, the first network node device determines whether its own received signal strength is greater than the received signal strength of the second network node device.
Step 450: in response to the received signal strength of the first network node device being greater than the received signal strength of the second network node device, the first network node device opens the network proxy service.
In an embodiment, when the received signal strength of the first network node device is greater than the received signal strength of the second network node device, the first network node device determines that it is a network node device with a greater received signal strength. At this time, the first network node device starts the network proxy service and notifies the second network node device to close the network proxy service, so that the network node device connected with the device to be accessed can be ensured to be the node device with the strongest received signal. Therefore, the network connection can be ensured to have higher communication quality.
Step 460: the first network node device sends a connection broadcast message.
The connection broadcast message broadcast by the first network node device may be received by the device to be accessed, or may be received by other network node devices in the same network. The connection broadcast message broadcast by the first network node device includes the received signal strength of the first network node device. After receiving the connection broadcast message of the first network node device, other network node devices in the same network may compare their own received signal strength with the received signal strength of the first network node device. Therefore, the network node device with the highest received signal strength in the network can be selected to start the network proxy service.
Step 470: a connection is established with a first network node device.
In an embodiment, after receiving the connection broadcast message, the device to be accessed determines whether the service type of the connection broadcast message is a proxy service. If not, the connection broadcast message is ignored. If so, continuing to judge whether the private identification information of the device sending the connection broadcast message is at least partially the same as the private identification signal of the device, for example, the vendor ID is the same. If so, connection with the first network node device is started. For example, the connection means may comprise a bluetooth connection.
Step 480: the first network node device sends a close proxy service message.
In an embodiment, the first network node device sends a message to the second network node device to cause it to close the proxy service.
Step 490: the network proxy service is closed.
In an embodiment, after receiving the shutdown message sent by the first network node device, the second network node device shuts down the network proxy service. Thereby, it can be ensured that only the first network node device is in a state of opening the proxy service in the same network.
In the same network, there may also be a third network node device that receives a private broadcast message sent by a device to be accessed after the first network node device starts the network proxy service. The third network node device may perform the same steps as the first network node device. Therefore, the network node equipment with the maximum received signal strength in the same network starts the network proxy service to be connected with the equipment to be accessed.
