Embodiment 1
[0047] This embodiment provides a method for accessing a wireless network, especially applied in a wireless local area network, such as figure 1 As shown, the method includes:
[0048] 101. The access point AP detects the number of terminals waiting to access the wireless network.
[0049]For example, the AP is set in a public place, and scans the terminal STA within the range covered by the AP. The AP determines how many STAs are waiting to access within its network coverage by receiving message frames from STAs, where the message frames can be Association Request Frames or Probe Request Frames.
[0050] 102. When detecting that the number of terminals waiting to access the wireless network is greater than or equal to a preset value, the AP starts a broadcast mode.
[0051] 103. The AP broadcasts the first message Message1 to terminals waiting to access the wireless network, and then starts an access procedure to enable the terminals to access the wireless network.

Embodiment 2
[0059] This embodiment provides a method for accessing a wireless network, which is applied to the process of associating a terminal STA with an access point AP, and adjusts the way the AP and the STA exchange messages during the four-step handshake process, such as figure 2 As shown, the method includes:
[0060] 201. An access point AP receives a message frame sent by a terminal STA.
[0061] For example, the AP can determine the number of STAs waiting to access the AP according to the request or interaction frame sent by the STA before the four-step handshake with the STA. The message frame can be an association request frame or a probe request frame, or other messages frame.
[0062] 202. The AP judges whether the number of STAs within its signal coverage is greater than or equal to a preset value according to the received message frame. If it is greater than or equal to the preset value, perform step 203; if it is less than the preset value, perform step 208.

Embodiment 3
[0084] This embodiment provides an access point of a wireless network, which may be an access point AP in a wireless local area network, such as image 3 As shown, the access point 30 includes:
[0085] A detection unit 31, configured to detect the number of terminals waiting to access the wireless network;
[0086] A broadcast start unit 32, configured to start the broadcast mode when the detection unit 31 detects that the number of terminals waiting to access the wireless network is greater than or equal to a preset value;
[0087] The sending unit 33 is configured to broadcast a first message Message1 to a terminal waiting to access the wireless network, and then start an access procedure so that the terminal accesses the wireless network.
[0088] Further, such as Figure 4 As shown, the access point 30 also includes:
[0089] a receiving unit 34, configured to receive a second message Message2 returned by one or more terminals;
[0090] A calculation and verification ...
