And the SIM card system can allocate virtual SIM cards for a user for a plurality of times, and the flow of the server which can be used by the virtual SIM cards allocated each time is the same.
In step 305, the control unit controls the virtual SIM card to establish a connection with the wireless communication module according to the information of the virtual SIM card.
The virtual SIM card is provided with information for providing the wireless communication module to access the server, and the control unit can control the wireless communication module to establish connection with the virtual SIM card after receiving the information of the virtual SIM card. The wireless communication module is provided with a level pin, when the connection with the virtual SIM card is not established, the level pin on the wireless communication module is always in a high level, the level pin is changed from the high level to a low level after the connection with the virtual SIM card is established, the control unit can determine whether the connection between the wireless communication module and the virtual SIM card is established or not by detecting the change of the level pin, and the connection is reestablished if the connection is not successful.
And step 306, the wireless communication module accesses the server according to the information of the virtual SIM card and transmits a feedback signal of the server to the control unit.
The wireless communication module can access the server according to the information of the virtual SIM card for establishing connection, and the server can enable the wireless communication module to be networked according to the access of the wireless communication module, and sends a feedback signal to the control unit according to the access of the wireless communication module to determine that the networking of the wireless communication module is successful.
And 307, the control unit controls the WIFI module to generate a WIFI signal according to the feedback signal.
After the wireless communication modules are successfully networked, the control unit can turn on the WIFI switch according to the signal fed back by the server, sends an instruction to start a WIFI program stored in the wireless communication modules, and the WIFI module performs function starting according to the turn-on state of the WIFI switch and generates a WIFI signal under the condition that the WIFI program is detected.
It should be noted that the terminal device detecting apparatus detects whether a terminal is connected with a WIFI signal in real time, generates a control instruction when it is determined that no terminal is connected with the WIFI signal, and transmits the control instruction to the control unit, and the control unit releases the information of the virtual SIM card according to the control instruction. The control unit sets a preset threshold value and transmits the preset threshold value to the terminal equipment detection device, so that the terminal equipment detection device can detect whether a terminal is connected with a WIFI signal within a preset range.
Compared with the prior art, in the method for providing the wireless fidelity WIFI signal in the embodiment, the server identifies the identity information of the user, and when the user is determined to be within the service range, the control unit allocates a virtual SIM card to the control unit, and the control unit connects the virtual SIM card with the wireless communication module according to the information of the allocated virtual SIM card, so that the wireless communication module can access the server according to the virtual SIM card, and the control unit controls the WIFI module to generate the WIFI signal according to the feedback signal of the wireless communication module, so that the user can surf the internet according to the traffic provided by the server, and does not need to purchase the traffic from an operator through a mobile phone card to surf the internet, thereby saving the internet cost of the user.

After steps 401 to 407, step 408 is performed.
And step 408, detecting the flow of the virtual SIM card, judging whether the flow is used up, if so, executing step 409, and if not, ending.
In the present embodiment, the traffic monitoring unit in the server detects the traffic usage of the virtual SIM card in real time, and since the available traffic of the virtual SIM card allocated each time is limited, when it is determined that the traffic of the virtual SIM card is used up, the traffic monitoring unit sends a signal to the SIM card system in the server to instruct the SIM card system in the server to reallocate a new virtual SIM card.
In step 409, the server allocates a new virtual SIM card and transmits the information of the new virtual SIM card to the control unit via the wireless communication module.
In this embodiment, a new virtual SIM card is assigned by the SIM card system in the server according to the signal instruction sent by the traffic monitoring unit. And after the information of the assigned new virtual SIM card is transferred to the control unit, the connection is established with the wireless communication module in the same manner as the virtual SIM card acquired for the first time, so step 405 is re-executed after step 409.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
