Example 2

The technical solutions of the embodiments of the present invention will be illustrated below with reference to preferred embodiments.

In the related art, many WIFI Access Points (APs) are controlled based on the AC, so that the APs of the equipment end are automatically switched within the whole WIFI coverage range of the equipment end, and roaming of the equipment end is realized.

The AC, that is, the wireless controller, is a network device, configured to manage APs in a wireless network in a certain area, and configured to centrally control the wireless APs, and is a core of the wireless network, and configured to manage all the wireless APs in the wireless network. Wherein, managing the AP may include: configuration issuing, relevant configuration parameter modification, radio frequency intelligent management, access security control and the like.

Fig. 2 is a schematic diagram of connection with a device side through an AC control AP according to one of the related art. As shown in fig. 2, when the device terminal X initiates a connection request, the AC determines the access point AP that is most matched with the device terminal X, and after the determination, pairs the closest access point a with the device terminal X;

when the equipment terminal X enters an area close to the access point B, the AC judges the access point which is most matched with the equipment terminal X, after judgment, the AC disconnects the access point A, and the closest access point B is paired with the equipment terminal X; similarly, when the device terminal X enters an area close to the access point C, the AC determines the access point that is most matched with the device terminal X, and after the determination, disconnects the access point B, and pairs the access point C that is most close to the device terminal X with the device terminal X.

Since the WIFI wireless roaming implementation is based on the AC to coordinate each device, the system adds one device, which increases the cost, and once the AC has a problem, the whole system will be broken down.

In the embodiment, an algorithm is implanted into each access point, so that an AC controller is saved, the work of the whole system cannot be influenced even if any access point AP has a problem, and various parameters can be flexibly set according to actual conditions.

The implementation principle of the embodiment is that each access point monitors the communication rate and the RSSI of all wireless device terminals, and simultaneously monitors real-time interaction related data between the access points. Within a certain time, the action of disconnecting or deleting the equipment end is carried out when the condition of a certain wireless equipment end is met, and other logics are provided to ensure the normal use of the user. As described further below.

Prepare all access points to the router, all APs can use the same SSID and password, and then use the setup tool to set up the relevant parameters of all APs.

The configurable parameters of this embodiment may include, but are not limited to, the following parameters:

enabling: 0/1, factory default closing state, and factory restoration closing state;

signal intensity: RSSI-80, which is configurable, and has a parameter by default subsequently, wherein 0 is the default preset value;

rate: 1Mbps, the method is configurable, a parameter is subsequently defaulted, and 0 is a default preset value;

weak signal holding time: 3 seconds, the method can be configured, one parameter is defaulted subsequently, and 0 is a default preset value;

disconnection protection time: and (3) the connection is not disconnected immediately after 120 minutes, until the time reaches the end of the equipment which can be disconnected again, a parameter is subsequently defaulted, and 0 is the default preset value.

In the connection process, when the device end is just powered on or just enters the network coverage, the device end can be connected with the AP with the best signal. And then, when the equipment end moves in the network coverage area, the equipment end is connected with the optimally matched connection point. All APs will exchange information with each other after power up.

The following describes an interaction procedure between the AP and the device side according to this embodiment.

Fig. 3 is a flowchart of an interaction method between an AP and a device according to an embodiment of the present invention. As shown in fig. 3, the method may include the steps of:

step S301 determines whether the roaming management function is enabled.

And judging whether the roaming management function is enabled or not, and if not, not carrying out the next roaming algorithm. Otherwise, step S302 is performed.

Step S302, the corresponding judgment is carried out on each connected equipment end in a circulating timing mode.

And under the condition that the roaming function is enabled, corresponding judgment is carried out on each connected equipment end in a circulating timing mode.

Step S303, determining whether the time from the current time of the device end to the last disconnection is less than the set disconnection protection time.

If the time from the current time of the equipment end to the last disconnection is judged to be less than the set disconnection protection time, neglecting the equipment end at this time, judging the next equipment line, and executing the step S302; otherwise, step S304 is executed.

Step S304, determining whether the signal strength and the communication rate at the device end are lower than the corresponding set values.

And if the time from the current time of the equipment end to the last disconnection is more than or equal to the set disconnection protection time, judging whether the signal intensity and the communication rate of the equipment end at the moment are lower than the corresponding set values. If yes, go to step S305; otherwise, the weak signal duration is cleared and step S302 is performed.

In step S305, the weak signal continuous timer is started to increase.

And if the signal intensity and the communication rate of the equipment end at the moment are judged to be lower than the corresponding set values, starting to continuously time and increase the weak signal.

Step S306, determine whether the duration is greater than the corresponding set value.

If the duration time is greater than the corresponding set value, executing step S307; otherwise, step S302 is performed.

And step S307, disconnecting the equipment end.

If the duration is larger than the corresponding set value, and the signal condition of the equipment end broadcasted by other AP access points through UDP is found to be better than that of the AP end, the optimal access point is screened out, the connection of the equipment end is disconnected, the disconnection time of the equipment end is recorded, the connection request of the equipment end is temporarily rejected, meanwhile, the access points except the optimal access point are informed to temporarily reject the connection request of the equipment end through TCP, the equipment end can only be connected with the optimal access point after being disconnected, and therefore the roaming function is achieved.

And if the duration is judged to be not more than the corresponding set value or the condition that the signal condition of the equipment end broadcasted by the UDP by other AP access points is not found to be better than that of the equipment end, connecting the equipment end with the access points.

In this embodiment, the interaction process between the AP access points may be: UDP broadcasting is carried out through UDP, and UDP broadcasting is carried out between APs through 15000 ports; through TCP communication, each AP establishes a TCP server for communication by taking 15000 as a port; the interactive content can be the interactive content of the connected device end, the intensity of the receiving signal of the device end, and the transmitting signal of the nearby device end.

For example, the access point a broadcasts the interactive content to the 15000 port through UDP, the access point B monitors the 15000 port through UDP to receive the interactive content of the access point a, and the access point C can monitor the interactive content of the access point a in the same manner. Similarly, the access point B, C may broadcast its data that it needs to interact with over UDP and a may listen to their data.

For another example, the access points A, B, C each create a TCP server, and create the devices to connect with each other, and then communicate with each other to exchange the corresponding data to be interacted.

Fig. 4 is a schematic diagram of an AP interacting with a device according to an embodiment of the present invention. As shown in fig. 4, when one device terminal X is at position 1, it is in a disconnected state due to no WIFI signal; then the equipment terminal X moves to the position 2, and the signal of the access point A is found to be strongest at the time, so that the equipment terminal X is connected to the access point A; then, the device terminal X arrives at the position 3, after a certain time, the access point a finds that the signal of the device terminal X is continuously weak through cyclic judgment, and simultaneously finds that the signal of the device terminal X broadcasted by the access point B is optimal in the access point B, then the access point a disconnects from the device terminal X, and simultaneously, the access point a temporarily rejects itself and notifies the access point C of temporarily rejecting the connection of the device terminal X. After the access point A, C disconnects from the device terminal X, only the access point B can connect, thereby implementing the roaming function.

The access method of the device in the embodiment is a decentralized device access method, each access point is implanted with an algorithm, and the access points in optimal matching are interacted and negotiated among the multiple access points in an interactive mode, so that the device end is connected with the access points in optimal matching, the connection between the target device and other access points is disconnected, the system can be prevented from needing AC, and meanwhile, even if any access point is damaged, other logic can be provided to ensure normal use of a user, a WIFI roaming system cannot be influenced, the technical problem of low access efficiency of the device is solved, and the technical effect of improving the access efficiency of the device is achieved.
