Problems solved by technology

However, in the local area network, the wireless router has a limit on the number of Wifi terminals connected to it.
That is to say, when the Wifi terminal is connected to the wireless router, if there are too many Wifi terminals connected to the wireless router, some Wifi terminals will not be able to join the LAN through the wireless router for network access.

Embodiment 1

[0090] image 3 For the present invention realizes the flowchart of the method for the embodiment 1 of Wifi access network, as image 3 shown, including:

[0091] Step 300, access the terminal user operation application, call the standard interface to send the command CMD_ONLINE, if yes, go to step 3010; otherwise, go to step 3020.

[0092] Step 3010, when the access terminal sends CMD_ONLINE, judge whether to access the Internet through Wifi or data service, if yes, execute step 30110; otherwise, execute 30120.

[0093] Step 30110, the access terminal executes the online command CMD_ONLINE in a standard way.

[0094] Step 30120, the access terminal builds an extended data frame: the attribute of the 0xbc item in the Framebody is 0x01, the valid data is: Sub and CMD_ONLINE, and the other bits are filled in accordance with the Wifi Direct standard format.

[0095] Step 30121. Send the extended data frame to the intermediate terminal through the P2P0 port of the device.

Embodiment 2

[0103] Figure 4 For the present invention realizes the flowchart of the method for the embodiment 2 of Wifi access network, as Figure 4 As shown, in Embodiment 1, in order to distinguish the data frames of the access terminal and the intermediate terminal in WIFI DIRECT mode, the access terminal constructs an extended data frame. When the intermediate terminal receives communication data, it includes:

[0104] Step 400, upon receiving a Wifi Direct frame, determine whether the frame type of the Wifi Direct frame is a data frame. When it is a data frame, execute step 4010; otherwise, execute step 4020.

[0105] It should be noted that the data frame and the extended data frame generated in Embodiment 1 are both Wifi Direct frames, that is to say, in the communication process between the terminal and the terminal in the Wifi Direct mode, according to the standard communication protocol, the transmission must be Wifi Direct frame.

[0106] Step 4010, judging whether the data...

Embodiment 3

[0119] Figure 5 For the present invention realizes the flowchart of the method for the embodiment 3 of Wifi access network, as Figure 5 As shown, when the wireless router receives the data frame initiated by the intermediate terminal, it includes:

[0120] Step 500: When receiving a Wifi frame, the wireless router determines whether the frame type is a data frame. When the frame type is a data frame, go to step 5010; otherwise, go to step 5020.

[0121] Step 5010, whether the data frame is an extended Wifi frame. When it is an extended Wifi frame, go to step 5011; otherwise, go to step 5020.

[0122] Step 5011, acquire valid data and control bit Subtype values ​​of Framebody in the frame.

[0123] Step 5012, except for the Type bit, use the standard method to analyze, and perform network access to obtain a Wifi response frame.

[0124] Step 5013, constructing the Wifi response frame as an extended Wifi response frame in the manner of constructing an extended Wifi frame....

Abstract

A method, system and terminal for realizing network access via Wifi. The method comprises: enabling, by both an access terminal and an intermediate terminal, a Wifi Station mode and a Wifi Direct mode thereof respectively, when the intermediate terminal receives an extended data frame used for representing that the access terminal accesses a network, extracting valid data for accessing the network, and carrying same in an extended Wifi frame and sending same to a wireless router; parsing, by the wireless router, the extended Wifi frame, sending the valid data to the network, obtaining response data and carrying same in an extended Wifi response frame, and returning same to the intermediate terminal; and converting, by the intermediate terminal, the extended Wifi response frame into an extended response data frame and then feeding back same to the access terminal, and parsing, by the access terminal, the extended response data frame to complete network access. In the embodiments of the present invention, by constructing an extended Wifi frame and an extended data frame, and sending data of an access terminal which is unable to access a Wifi network to a wireless router by an intermediate terminal, the occurrence of the case where a Wifi terminal cannot access the network via the wireless router is avoided, thereby improving the validity of network access.
