Abstract
A critical threshold value of the number of connections of VoIP communication by a wireless LAN is set to an access point apparatus. The access point apparatus records identification information of terminals each of which has transmitted a request for connection of VoIP communication. After the number of terminals whose identification information have been recorded reaches the critical threshold value, the access point apparatus transmits a packet indicating release an association to a terminal whose identification information is newly recorded.
