- Step 7013 Send the extended Wifi frame through the device wlanO port.
- the extended Wifi frame is sent to the wireless router through the intermediate terminal, that is, the extended Wifi frame is constructed, and the valid data of the visited network is carried in the frame information, thereby realizing the access terminal to the intermediate terminal and the wireless router. Communication.
- step 7020 is performed.
- Step 7020 parsing the frame in a general manner and responding. It should be noted
- Step 7021 Encapsulate the response data into a standard Wifi Direct frame according to a standard format.
- Step 7022 Send the standard Wifi Direct frame through the device p2p0 port.
- steps 7020 to 7022 are method steps of the related art. This section is set forth to provide a clearer description of the present invention and further to illustrate that there is no communication conflict between the present invention and the related art.
- FIG. 8 is a flowchart of a method for implementing a Wifi access network according to Embodiment 3 of the present invention. As shown in FIG. 8, when a wireless router receives a data frame initiated by an intermediate terminal, the method includes:
- Step 800 When the wireless router receives the Wifi frame, determine whether the frame type is a data frame. When the frame type is a data frame, go to step 8010; otherwise, go to step 8020.
- Step 8010 Whether the data frame is an extended Wifi frame. When the Wifi frame is extended, step 8011 is performed; otherwise, step 8020 is still performed.
- Step 8011 Obtain valid data of the Framebody in the frame and a control bit Subtype value.
- Step 8012 Except for the Type bit, the method is parsed in a standard manner, and network access is performed to obtain a Wifi response frame.
- Step 8013 Construct a Wifi response frame as an extended Wifi response frame according to how to construct an extended Wifi frame.
- Step 8014 Send the extended Wifi frame through the Wifi wireless link.
- the extended Wifi frame is sent out through the Wifi wireless link, and the invented method is the same as the method of transmitting the normal Wifi frame.
- Step 8020 Parse the frame in a general manner and respond.
- Step 8021 Encapsulate the response data into a standard Wifi frame according to a standard format.
- Step 8022 Send the Wifi frame through the Wifi wireless link.
- FIG. 9 is a flowchart of a method for implementing a Wifi access network according to Embodiment 4 of the present invention. As shown in FIG. 9, when a wireless router receives a data frame initiated by an intermediate terminal, the method includes:
- Step 900 The access terminal receives the WiFi frame, and determines that the frame type is a data frame. When the frame type is a data frame, step 9010 is performed; otherwise, step 9020 is performed.
- Step 9010 Whether the data frame is an extended Wifi response frame. When the Wifi response frame is extended, step 9011 is performed; otherwise, step 9020 is still performed.
- Step 9011 Obtain valid data of the Framebody in the frame and a control bit Subtype value.
- Step 9012 Construct a response extended data frame: In the Framebody, the Oxbc item attribute is 0x01, the valid data is Sub+Data, and the other bits are filled according to the WiFi Direct standard format.
- Step 9013 Send the response extended data frame to the device through the P2P0 port.
- Step 9020 parsing the frame in a generic manner and responding.
- Step 9021 Encapsulate the response data into a standard Wifi frame according to a standard format.
- Step 9022 Send the standard WiFii frame through the device wlanO port.
- the data of the access terminal that cannot access the Wifi network is sent to the wireless router through the intermediate terminal by constructing the extended Wifi frame and the extended data frame, thereby avoiding the situation that the Wifi terminal cannot access the local area network through the wireless router. The occurrence of this, thereby improving the effectiveness of network access. Therefore, the present invention has strong industrial applicability.
