Claim Text:
1. A method for accessing a wireless local area network, the method comprising: obtaining, by an access point, an uplink access collision value, wherein an uplink access collision is caused by multiple stations associated with the access point simultaneously sending data to the access point; and sending, by the access point, a first clear to send signal to all the stations associated with the access point when it is determined that the uplink access collision value exceeds a preset threshold, wherein a receiver address of the first clear to send signal is a media access control address of a first station associated with the access point, so as to instruct the first station to send data to the access point, and the first clear to send signal is not responsive to any signal; monitoring, within a preset waiting time, whether the access point receives the data sent by the first station; obtaining another uplink access collision value if the access point receives within the preset waiting time the data sent by the first station; and sending a second clear to send signal to all the stations associated with the access point if the access point does not receive within the preset waiting time the data sent by the first station, wherein a receiver address of the second clear to send signal is a media access control address of a second station associated with the access point, so as to instruct the second station to send data to the access point, and the second clear to send signal is not responsive to any signal.
