Abstract
A method, program product and system of preventing or limiting the number of simultaneous sessions in a wireless local area network (WLAN). The method includes: determining whether subscriber terminal information has been changed between an old session and a new session, maintaining a connection with the old session if the subscriber terminal information has not changed, and establishing and authenticating the new session and disconnecting the old session if the subscriber terminal information has changed. A medium access control (MAC) address and a WLAN radio network identification can be compared between the old session and the new session to determine whether subscriber terminal information has been changed.
