The embodiment of the invention discloses an access control method and a mobile terminal. The method comprises the steps of obtaining a wireless access point existing in a preset space; judging whether the wireless access point is the wireless access point accessed by the mobile terminal or not; if the wireless access point is the wireless access point accessed by the mobile terminal, obtaining pre-stored accumulated use duration and average use duration of the wireless access point; if the accumulated use duration is longer than or equal to a first preset threshold and the average use duration is longer than or equal to a second use threshold, obtaining access authentication information of the wireless access point; and sending the access authentication information to the wireless access point, thereby accessing the wireless access point. According to the embodiment of the method and the mobile terminal, the network access security and stability of the mobile terminal can be improved.
