Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following embodiments and accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Example 1

The present embodiment provides a network access control method for a wireless terminal, which enables the wireless terminal to maintain network connection and maintain network connection with relatively good wireless signal quality as much as possible. It is assumed that the execution subject may be a Wireless Controller, specifically, a Wireless Access Point Controller (Wireless Access Point Controller), which may be a network device for centralized controlling Wireless Access points, and is a core of the Wireless network and responsible for managing all Wireless Access points in the Wireless network. And a wireless access point (wireless AP), which may be connected to a wireless terminal to enable the wireless terminal to access the internet, in this specification, the wireless controller is referred to as AC for short, and the wireless AP is referred to as AP for short. The specific flow diagram of this embodiment is shown in fig. 1, and includes:

step 102: and determining a target wireless access point which meets the optimal wireless connection condition with the wireless terminal from the plurality of wireless access points.

As described above, in order to achieve the full coverage of the network, a plurality of APs are usually installed and controlled by the AC. Fig. 2 is a schematic diagram of a connection relationship between a wireless controller and a wireless access point, where the left and right diagrams are two connection relationships, respectively.

Specifically, in the left drawing, the AC and each AP are independent from each other, the AC and each AP may be connected by a wired manner (indicated by a solid line), and the AC may implement network control on each AP. In the right drawing, an AC and one of the APs are assembled in one device, that is, the device has both functions of the AC and the AP, and the AC is connected with the other APs through the APs in the device itself in a wireless manner (indicated by dotted lines), so as to control the APs. For example, a Mesh network, i.e., a wireless Mesh network, is a dynamic network architecture that can be continuously expanded, any two devices can maintain wireless interconnection, in an actual Mesh network, a device having an AC function may be referred to as a master device, and the other devices may be referred to as slave devices, and an AC in the master device may play a role in controlling all APs.

Fig. 3 is a schematic diagram illustrating an application scenario of the network access control method for a wireless terminal. In which multiple APs may be located in different rooms, such as a family of houses, and 3 APs are located in different rooms. The wireless terminals (terminals connected to the internet by wireless) may include a door lock, a television, a camera, and a curtain, and the positions of the wireless terminals are usually fixed and unchangeable, so it is necessary to maintain connection to a better network, which not only ensures network experience, but also makes full use of network resources, i.e. the wireless terminals in this specification may be fixed wireless terminals.

Taking the door lock in fig. 3 as an example, the door lock may be an intelligent door lock that needs to access the internet, and it can be understood that, due to the distance between the door lock and each AP and the consideration of shielding of wireless signals, it is desirable to maintain a wireless network with the AP1, that is, the AP1 may be the most probable choice for maintaining the best quality of wireless signals between the door lock and the door lock. Similarly, other wireless terminals may have their own optimal selection, such as the most optimal selection for tv is likely AP1, and certainly is likely AP2, while the most optimal selection for cameras is AP2, and the most optimal selection for blinds is AP 3.

Therefore, in this step, the AC can determine a target AP satisfying the optimal condition for wireless connection with the wireless terminal from the plurality of APs. Specifically, the optimal condition for wireless connection may include that the wireless signal quality is optimal, and in this step, the wireless signal quality between different wireless access points and each AP may be detected from multiple APs, so as to determine an AP corresponding to the optimal wireless signal quality, and determine the AP as the target AP.

Specifically, the AC may control the wireless terminal to connect to different APs respectively, for example, taking the door lock in fig. 3 as an example, the door lock may be network-connected to the AP1, the AP2, and the AP3 respectively by adding the door lock to a blacklist of different APs, so as to detect the wireless signal quality between different APs and the door lock respectively, for example, the quality of the wireless signal may be determined individually or comprehensively by one or more of the wireless signal strength dBm, the wireless transmission rate Mbps, the ping value, and the like, and the optimal wireless signal quality is determined by using the quality of the wireless signal, so as to determine the AP corresponding to the optimal wireless signal quality as the target AP.

In practical application, the optimal condition for wireless connection may further include that the wireless transmission distance is the shortest, and in this step, the wireless connection distances between different APs and the wireless terminal may be detected from the multiple APs, and the AP corresponding to the shortest wireless connection distance is determined as the target AP.

Specifically, the AC may control the wireless terminal to connect with different APs respectively, and obtain wireless signal strengths between the wireless terminal and different APs respectively, so that the wireless terminal in the room may be located based on a propagation model method of the wireless signal strengths, a fingerprint identification method, and the like. Therefore, the wireless connection distance between each AP and the wireless terminal can be obtained, and accordingly the AP with the shortest wireless connection distance between the AP and the wireless terminal can be used as the target AP.

In practical application, the target AP meeting the optimal condition of wireless connection with the wireless terminal may be determined by combining the two manners. For example, the results determined by the two methods may be compared comprehensively, if the results are consistent, the target AP may be determined directly, and if the results are inconsistent, a certain result may be set as a first choice, and the like.

Step 104: and respectively adding the wireless terminal into blacklists of other wireless access points.

Having determined the optimal selection of APs, i.e., the target AP, for the wireless terminal in the foregoing steps, the wireless terminal may then try to maintain network connectivity with the optimally selected target AP. The connection maintaining mode can be realized by rejecting the connection establishment between the wireless terminal and other APs.

Specifically, a blacklist for preventing wireless connection may be created for the AP, and a wireless terminal belonging to the blacklist cannot establish network connection with the AP. For example, in fig. 3, a black list may be created for each AP, and the wireless terminal may be added to the black list to control that the wireless terminal cannot establish a network connection relationship with the AP, so that the wireless terminal is added to a desired target AP.

For example, in fig. 3, if it is determined that the target AP meeting the optimal condition for wireless connection with the door lock is AP1, the door lock may be added to blacklists of other APs, where the other APs may be APs other than the target AP, among the multiple APs. In fig. 3, if the wireless terminal is a door lock and the target AP is AP1, the other APs may be AP2 and AP3, that is, the door lock may be added to the blacklists of AP2 and AP3, respectively, so that the door lock and AP1 can keep connecting with AP1 when accessing the internet. For example, if the wireless network module of the wireless device is restarted or disconnected, the wireless device can be connected to the desired AP again.

Similarly, if it is determined that the target AP satisfying the optimal condition for wireless connection with the camera is AP2, the camera may be added to the black list of AP1 and AP 3. The blacklist may be added by adding one or all of an IP (Internet Protocol, Protocol for interconnecting networks) and a MAC (Media Access Control Address) of the wireless terminal to the blacklist.

Step 106: and when detecting that the target wireless access point meets the preset abandon condition, removing the wireless terminal from the blacklist of other wireless access points.

In practical applications, the AP may be disconnected, such as power off, damage, and the like. Therefore, to further enable the wireless terminal to maintain the network connection, when a target AP is detected to be dropped, the wireless terminal may be removed from the blacklist of other APs so that the wireless terminal may connect to one of the other APs. For example, in fig. 3, if the AC detects that the AP1 is unlinked, the door lock may be removed from the blacklist of AP2 and AP3 so that the door lock may be connected to one of the AP2 or AP3 to maintain network connectivity.

That is, the abandon condition may be preset as an AP loss, and when the target AP loss is detected, it may be determined that the preset abandon condition is satisfied, and accordingly, the wireless terminal may be removed from the blacklist of other APs.

In practical applications, the AP may have too low wireless signal transmission power for its own reason, so that the AP no longer has an optimal wireless connection condition with the wireless terminal. To further enable the wireless terminal to maintain network connectivity and connect to a relatively good network, the wireless terminal may be removed from the blacklist of other APs when the wireless signal transmission power of the target AP is detected to be below a threshold. Still referring to fig. 3, if the AC detects that the wireless transmission power of the AP1 is below 30% of the maximum power, the door lock may be removed from the blacklist of AP2 and AP3 so that the door lock may select one of the AP2 or AP3 when disconnecting from the AP1 or re-accessing the network, thereby maintaining the network connection and at a relatively good network quality.

That is, the abandoning condition may be preset such that the wireless transmission power of the AP is lower than the proportional threshold of the highest power, and when it is detected that the target AP satisfies the condition, it may be determined that the preset abandoning condition is satisfied, and accordingly, the wireless terminal may be removed from the blacklist of other APs.

According to the foregoing, the target AP may satisfy the predetermined drop condition due to the loss of association, thereby causing the wireless terminal to connect to other APs. In practical applications, the reason for powering off the target AP may be the power-off operation of the user, and it is likely that the target AP will be powered on again in a short time, so the powered-on AP1 is also likely to be the optimal choice for the wireless terminal.

Therefore, in order to enable the wireless terminal to maintain a better wireless connection, the method may further include: and when detecting that the target wireless access point recovers the optimal wireless connection condition, adding the wireless terminal into the blacklist of other wireless access points again.

Specifically, after detecting that the target AP is lost and the wireless terminal is removed from the blacklist of other APs, the AC may further detect whether the target AP is connected again at regular time, and detect whether the optimal condition of wireless connection between the target AP and the wireless terminal is recovered, and if so, the wireless terminal may be added to the blacklist of other APs again, so that the wireless terminal is connected to the target AP again.

For example, in fig. 3, if the AC detects that the AP1 is disconnected, the IP and/or MAC of the door lock may be removed from the blacklist of AP2 and AP3 so that the door lock may connect to both APs to maintain network connectivity. After that, whether the AP1 restores connection with the AC can be detected regularly, if so, whether the optimal condition of wireless connection between the AP1 and the door lock is satisfied again can be detected, and if so, the IP and/or MAC address of the door lock can be added into the AP2 and the AP3 again, so that the door lock can maintain better network connection with the AP 1.

In practical applications, if the target AP still does not recover the optimal conditions for wireless connection for a period of time, the AP location or position may change, for example, in fig. 3, if the AP1 is damaged, the user is forced to change the AP installation mode, and the positions of the AP2 and the AP3 may be adjusted to achieve the network coverage as much as possible. Therefore, it is necessary to find a target AP satisfying the optimal condition for wireless connection for the wireless terminal again, and then the AC may prompt the user to adjust or modify the connection of the wireless terminal after a preset period of time, that is, step 102 and step 104 may be executed again.

According to the method provided by the embodiment, the wireless controller can determine the target wireless access point which satisfies the optimal wireless connection condition with the wireless terminal from the plurality of controlled wireless access points, and accordingly, the wireless terminal can be respectively added into the blacklists of other wireless access points except the target wireless access point, so that the wireless terminal can keep better network connection. When detecting that the target wireless access point meets the preset abandon condition, the wireless terminal can be removed from the blacklists of other wireless access points, so that the wireless terminal can keep network connection with one of the other wireless access points, and relatively better network connection is kept.

In implementing the present solution, the radio controller 302 in one entity device may be selected as the execution subject.
