WiFi AP terminal wide area network access method

Technical Field

The invention relates to a WiFi AP terminal wide area network access method.

Background

At present, intelligent terminals are increasingly popularized, most of the intelligent terminals have a direct internet surfing function, and part of the terminals can also be used as WiFi hotspots to provide internet surfing for other devices. However, in a mobile application place or when there is a specific requirement, the intelligent terminal device needs to be configured with a data communication module (such as a 3G or 4G module) to have the internet access function, which increases the manufacturing cost and the application cost of the device. There are two existing methods for accessing a wide area network: one is that the mobile phone is used as a hot spot, and the other is that a mobile phone system is transformed through point-to-point communication to realize a gateway function. The first method needs an operator to actively switch the mobile phone wifi to a hot spot mode in the using process, and the operation is complex. And the second type is only suitable for the mobile phone with the customized firmware, and cannot be used immediately. The prior art does not solve the problem of surfing the Internet of intelligent equipment without direct surfing capability.

Detailed Description

The technical scheme of the invention is specifically explained below with reference to the accompanying drawings.

In the existing Station, access to the AP is usually performed, and the AP accesses to the internet through its own internet module (which may be a local area network module or a 3G/4G module). The intelligent terminal device serving as the AP in this embodiment does not have an internet access module and does not have a function of directly accessing the internet, and therefore, one of the mobile phones connected as the Station needs to be designated as an internet access device. By running the built-in specific programs of both sides, the AP forwards the Internet surfing request to the Station, and the Station serves as an Internet surfing agent to realize the Internet surfing function. The invention provides a WiFi AP terminal wide area network access method, which comprises an intelligent terminal device and a mobile phone, wherein the intelligent terminal device is provided with a first application module, the mobile phone is provided with a second application module, and further, in the embodiment, the first application module is an application program A arranged on the intelligent terminal device, and the second application module is an application program B arranged on the mobile phone.

Further, in this embodiment, the intelligent terminal device needs to have a WiFi hotspot function, and an application a is built in the intelligent terminal device and used for sending the device identification code and setting the internet access agent. After the intelligent terminal device starts the WiFi hotspot to serve as the AP, the application program A communicates with an application program B on the mobile phone, sends a device identification code, and receives the internet access agent information sent by the device identification code. And then all the internet access requests of the intelligent terminal equipment are forwarded to an application program B by the application program A for proxy processing.

Further, in this embodiment, an application B for controlling the intelligent terminal device is installed on a mobile phone having 3G or 4G mobile communication. The mobile phone needs to start WiFi to be connected to the intelligent terminal device to be used as a Station, and an application program B is started. And the application program B communicates with the intelligent terminal equipment serving as the AP to obtain the equipment identification code of the terminal and confirm whether the terminal is allowed to surf the internet or not. And under the condition of allowing to surf the internet, the application program B sends internet agent information to the intelligent terminal equipment. And the application program B accesses the Internet through a 3G or 4G module of the mobile phone and processes the Internet access request of the intelligent terminal equipment in an agent mode.

Further, in this embodiment, the method is specifically implemented as follows:

step S1: the intelligent terminal device starts a WiFi hotspot as an AP, starts an application program A and waits for the access of a mobile phone;

step S3: the application program A allocates IP to the mobile phone in a DHCP form through a WiFi hotspot; in DHCP communication, notifying a WiFi communication module of the mobile phone that a gateway and a DNS of a WiFi hotspot are empty, and also designating the gateway and the DNS of an existing mobile operator of the mobile phone, so that in communication, the mobile phone cannot guide network communication information to the intelligent terminal equipment; in this embodiment, DHCP is a network protocol, and when a device accesses a server using the protocol, an IP address is automatically assigned to the access device, and a gateway and a DNS are set so that the access device can access an external network. The intelligent terminal automatically starts an application program A and DHCP service after being started, the application program A empties a gateway and a DNS of DHCP, and the gateway and the DNS received by the access equipment are naturally empty; the DHCP protocol running on the mobile phone is a client, and runs when needed, if the client cannot surf the internet or wants to connect to a server through WiFi, the client can automatically run when the WiFi is started;

step S4: the mobile phone starts the application program B, sends inquiry information to the intelligent terminal equipment through the WiFi communication module, and inquires the equipment identification code of the intelligent terminal equipment;

step S5: the first application module responds to the query information and sends a device identification code of the intelligent terminal device to the second application module through the WiFi hotspot;

step S6: the application program B judges whether the equipment identification code is legal or not according to a built-in preset equipment list, and the step is switched to the step S7 after the equipment identification code is judged to be legal; if the terminal equipment is illegal, the intelligent terminal equipment cannot perform subsequent interactive response and cannot complete the internet surfing function;

step S7: the application program B starts an HTTP proxy service function of the mobile phone, acquires a proxy port number and sends the proxy port number to an application program A supporting the HTTP proxy service function through a WiFi communication module; in this embodiment, HTTP is also a network protocol, which is owned by the operating system as with the current DHCP in both the mobile phone and the smart device; both HTTP and DHCP can be started or stopped by programs, and configuration can be modified in the programs and then the programs are started to run;

step S8: the application program A sets the proxy port number of the HTTP of the intelligent terminal equipment according to the acquired proxy port number; the application program A adopts a TCP/IP protocol to send the internet surfing request data to an application program B through a WiFi hotspot according to the proxy port number and the IP allocated to the mobile phone;

step S9: the application program B is used as an HTTP proxy, an Internet surfing request is sent through an Internet surfing module of the mobile phone, such as a 3G or 4G Internet surfing module and a local area network Internet surfing module, and received response data is sent to the application program B through a WiFi communication module, so that HTTP network communication capacity of the application program A is achieved.

Further, in the embodiment, in step S9, the application B is only responsible for forwarding the HTTP, and does not modify the internet access request data or the response data, and only functions as a proxy for the HTTP. The Internet access is connected with the wide area network in an HTTP mode.

The above are preferred embodiments of the present invention, and all changes made according to the technical scheme of the present invention that produce functional effects do not exceed the scope of the technical scheme of the present invention belong to the protection scope of the present invention.
