A wireless communication apparatus (for example, a wireless LAN access point 4) sends to an opposite apparatus during connection (for example, a wireless LAN terminal 6) advance notice of disconnection that notifies disconnection to a transmission frame before sending a disconnection frame (a deauthentication frame). After the advance notice of disconnection, the disconnection frame is sent and a disconnection process is executed. Since advance notice of disconnection is executed before the disconnection frame is sent, unless the wireless communication apparatus or the opposite apparatus during connection receives advance notice of disconnection before the disconnection frame is received, the disconnection frame is ignored, that is, disconnection frames from apparatuses except the apparatus during connection is ignored, then, illegal connection disconnection can be prevented. |
