Referring to fig. 2, fig. 2 is a schematic flowchart of step S13 in the embodiment of fig. 1.

Step S21: and creating a virtual network card, and performing Wi-Fi connection with the wireless access node with the maximum signal strength through the virtual network card.

The AP1 creates a virtual network card, which is a coexistence mode of the STA mode and the AP mode, i.e. when the Wi-Fi module is used as the AP, it may also exist as one STA mode, for example: the Wi-Fi module is used as an AP, so that a mobile phone or a computer of a client can be accessed, and meanwhile, the Wi-F module can be used as an STA to be accessed to a router or an upper server for data uploading. And the AP1 initiates Wi-Fi connection to the wireless access node with the maximum signal strength in the received wireless access node list by using the virtual STA, so that the AP1 communicates with the wireless access node with the maximum signal strength in the wireless access node list.

After that, the AP2 performs data transmission and reception with the mobile terminal at the rate set supported by both parties.

After the AP2 completes the synchronization configuration with the AP1, the virtual STA of the AP1 disconnects the Wi-Fi connection with the AP2, and at the same time the AP1 changes its BSSID to the BSSID of the AP2.

Referring to fig. 3, fig. 3 is a flow chart of a second embodiment of a wireless communication method according to the present application, where the wireless communication method is used in a wireless communication system, and the wireless communication system includes a mobile terminal and at least two wireless access nodes.

Step S31: the mobile terminal establishes a communication connection with a radio access node.

The mobile terminal is connected with a last wireless access node, authentication information is transmitted to the connected wireless access node, and monitors all surrounding wireless access nodes and acquires wireless access node list information. The wireless access node stores authentication information with the mobile terminal, including at least any one of a MAC address and an IP address of the mobile terminal, a data transmission rate set negotiated by the wireless access node with the mobile terminal, a unicast key, a multicast key, and the like.

Step S32: the mobile terminal sends wireless access node list information to the connected wireless access node when the signal intensity corresponding to the connected wireless access node is smaller than an intensity threshold value; the wireless access node list information comprises wireless access nodes connected and connectable with the mobile terminal and signal intensity of each wireless access node.

The mobile terminal monitors Beacon frames of all surrounding wireless access nodes, and when the mobile terminal finds that the signal intensity corresponding to the connected wireless access node is smaller than the intensity threshold value, the mobile terminal sends the wireless access node list information with the same hot spot name under the current channel to the connected wireless access node. The wireless access node list information includes information of wireless access nodes to which the mobile terminal is connected and connectable, and the information of the wireless access nodes includes BSSID and RSSI thereof, i.e., MAC address and signal strength of the wireless access nodes. The connected radio access node will be described below using AP1.

Step S33: the connected wireless access node acquires the wireless access node with the highest signal strength based on the wireless access node list information.

The AP1 receives the radio access node list information from the mobile terminal and acquires a radio access node with the highest signal strength from the radio access node list. The AP2 will be used hereinafter to describe the radio access node with the greatest signal strength.

After Wi-Fi communication is established between the AP1 and the AP2, authentication information of the AP1 and the mobile terminal is sent to the AP2.

After the AP2 completes the synchronization configuration with the AP1, the virtual STA of the AP1 disconnects the Wi-Fi connection with the AP2, and at the same time the AP1 changes its BSSID to the BSSID of the AP2. And the mobile terminal continues to monitor Beacon frames of all surrounding wireless access nodes, and when the signal strength of the currently connected wireless access node is lower than the strength threshold value, the mobile terminal reports the wireless access node list information to the currently connected wireless access node and repeats the steps.

And the mobile terminal monitors Beacon frames of all surrounding wireless access nodes, and when the mobile terminal finds that the signal intensity corresponding to the AP1 is smaller than the intensity threshold value, the mobile terminal sends the wireless access node list information with the same hot spot name under the current channel to the AP1. The wireless access node list information includes information of wireless access nodes to which the mobile terminal is connected and connectable, and the information of the wireless access nodes includes BSSID and RSSI thereof, i.e., MAC address and signal strength of the wireless access nodes.

The AP1 selects a wireless access node AP2 with the maximum signal strength from the received wireless access node list information to initiate connection, and the AP1 creates a virtual network card which is a coexistence mode of an STA mode and an AP mode. AP1 initiates a Wi-Fi connection with AP2 using the virtual STA to enable AP1 to communicate with AP2. The AP1 synchronizes the authentication information with the mobile terminal to the AP2, and the AP2 synchronizes the configuration of the AP1, including saving the MAC address and the IP address of the mobile terminal, setting a unicast key, a multicast key, and the like, and the AP2 sets the BSSID of the AP1, that is, the MAC address of the AP1, to its own BSSID. After that, the AP2 performs data transmission and reception with the mobile terminal at the rate set supported by both parties.

After the AP2 synchronizes the configuration of the AP1, the AP1 disconnects the STA network card connected to the AP1 and changes its BSSID to the BSSID of the AP2. And the mobile terminal continues to monitor Beacon frames of all surrounding wireless access nodes, and when the signal strength of the currently connected wireless access node is lower than the strength threshold value, the mobile terminal reports the wireless access node list information to the currently connected wireless access node and repeats the steps. The mobile terminal remains connected to the AP throughout the process.
