Detailed ways

Fig. 1 is a flowchart of Embodiment 1 of the WiFi connection method of the present invention. As shown in Fig. 1, the method includes:

Step 101, the WiFi agent receives the NFC connection request sent by the mobile terminal, and establishes an NFC connection with the mobile terminal;

In this embodiment, for the convenience of users, in places such as coffee shops, airports, restaurants, etc. that provide users with free WiFi Internet access functions, multiple WiFi agents can be set in the store, through which WiFi agents can be used to realize WiFi access that users do not need to log in to. Network operation.

Specifically, the WiFi agent can be reasonably deployed in a suitable location according to actual needs, which is convenient for users to operate. A near field communication (Near Field Communication, hereinafter referred to as NFC) module can be set in the WiFi agent, and correspondingly, an NFC module is also set in the user's mobile terminal, so that when the user needs to connect to a WiFi access point (Access Point, hereinafter referred to as AP), first use the NFC module to perform a "swipe card" operation to swipe the WiFi proxy, triggering the mobile terminal to send an NFC connection request to the WiFi proxy. When the WiFi proxy receives the NFC connection request sent by the user's mobile terminal, it establishes and maintains the NFC connection with the mobile terminal. It can be seen that only when the user enters the store and is close enough to at least one WiFi agent set in the store, can the incoming communication be established between the NFC module of the mobile terminal and the NFC module set in the WiFi agent. , and users outside the store generally do not connect to the WiFi agent set up in the store.

Step 102, WiFi agent establishes WiFi connection with WiFi AP;

In this embodiment, the WiFi AP pre-sets the WiFi connection strategy as a connection strategy based on Media Access Control (Media Access Control, hereinafter referred to as MAC) address binding, that is, if any device wants to connect to the WiFi AP, it needs the WiFi connection strategy. The MAC address of the device bound to the AP. To this end, a MAC address pool is set in the WiFi AP to store the MAC addresses of the bound devices. It is worth noting that, in this embodiment, the MAC address of each WiFi agent is pre-added in the MAC address pool of the WiFi AP during initialization, thereby allowing each WiFi agent to automatically establish a WiFi connection with the WiFi AP. It can be seen that by pre-adding the MAC address of each WiFi agent in the MAC address pool of the WiFi AP, it is equivalent to the security authentication of the WiFi agent, because when the MAC address of a WiFi agent is not in the MAC address pool of the WiFi AP , the WiFi AP will not connect with the WiFi agent.

Specifically, when the WiFi agent receives the NFC connection request sent by the mobile terminal and establishes an NFC connection with the mobile terminal, it immediately establishes a WiFi connection with the WiFi AP. Specifically, in addition to the NFC module, the WiFi agent is also provided with a WiFi communication module, so that the WiFi agent activates the internal WiFi communication module, and automatically establishes a WiFi connection with the WiFi AP through the WiFi communication module.

Step 103, the WiFi agent receives the MAC address of the mobile terminal sent by the mobile terminal through the NFC connection;

Step 104, the WiFi agent sends the MAC address to the WiFi AP through the WiFi connection, so that the WiFi AP adds the MAC address into the MAC address pool, and binds the MAC address of the mobile terminal;

Based on the above-mentioned WiFi connection strategy, for a mobile terminal that currently wants to access a WiFi AP, it is necessary to provide the MAC address of the mobile terminal to the WiFi AP so that the WiFi AP can bind the MAC address of the mobile terminal as the mobile terminal. Provide WiFi Internet service.

Specifically, the mobile terminal transmits its own MAC address to the WiFi agent through the established NFC connection with the WiFi agent, and then the WiFi agent forwards the MAC address to the WiFi AP through the established WiFi connection with the WiFi AP, Therefore, after receiving the MAC address of the mobile terminal, the WiFi AP adds the MAC address to the MAC address pool, thereby binding the MAC address of the mobile terminal.

It should be noted that, in this embodiment, the mobile terminal MAC address is preferably obtained by the mobile terminal through an application program (Applet) preset in the internal Single Wire Protocol (Single Wire Protocol, hereinafter referred to as SWP) card. It can be understood that the MAC address can also be obtained by configuring a client in the mobile terminal. However, in order to simplify operations and avoid additional application development, the former method is preferred.

Step 105, the WiFi agent receives the SSID sent by the WiFi AP through the WiFi connection, and sends the SSID to the mobile terminal through the NFC connection, so that the mobile terminal uses the SSID to communicate with the WiFi The AP establishes a connection.

After the WiFi AP binds the MAC address of the mobile terminal, it feeds back its own service set identifier (ServiceSet Identifier, hereinafter referred to as SSID) to the WiFi agent through the WiFi connection with the WiFi agent, and then the WiFi agent feeds back to the mobile terminal through the NFC connection , so that the mobile terminal accesses the WiFi AP according to the SSID, and performs WiFi Internet access applications.

In addition, it is worth noting that after the WiFi agent receives the SSID sent by the WiFi AP through the WiFi connection, in order to further save the power consumption of the WiFi agent, it can also include:

The WiFi agent controls the WiFi communication module in itself to be in a dormant state.

In this embodiment, when the WiFi agent receives the NFC connection request sent by the mobile terminal, it establishes an NFC connection with the mobile terminal, and establishes a WiFi connection with the WiFi AP. Furthermore, the WiFi agent receives the MAC address of the mobile terminal sent by the mobile terminal through the NFC connection, and sends the MAC address to the WiFi AP through the WiFi connection, so that the WiFi AP adds the MAC address to the MAC address pool, so as to Bind the MAC address of the mobile terminal. After binding the MAC address of the mobile terminal, the WiFi AP sends its own SSID to the WiFi agent through the WiFi connection, and the WiFi agent sends the SSID to the mobile terminal through the NFC connection, so that the mobile terminal uses the SSID to establish a connection with the WiFiAP. The mobile terminal sends its own MAC address to the WiFi AP through the NFC connection between the WiFi agent and the WiFi connection between the WiFi agent and the WiFi AP, so that the WiFi AP will feed back its own SSID to the mobile terminal after binding the MAC address. Terminal, in this embodiment, the mobile terminal establishes an NFC connection with a WiFi agent that is pre-securely verified through the WiFi AP, and automatically accesses WiFi through the WiFi agent. Compared with the prior art, the WiFi connection method provided by this embodiment does not require consultation Obtaining the access password or text message verification not only ensures security, but also prevents other non-store users from spoofing the Internet, and is simple and practical, which improves the user experience.
