Abstract

Provided is a technology which pertains to wireless LAN communication systems and with which it is possible to achieve convenience in that a terminal of a user who is external to an organization can temporarily use the system and to ensure security in such a case. The present communication system comprises: a first terminal which is used by a user internal to an organization; a second terminal which is used by a user external to the organization; and a communication device which has a display function and a wireless LAN access point function inside the organization. The first terminal connects to the communication device via a wireless LAN. The second terminal connects, under permission from the first terminal, to the communication device via the wireless LAN. The second terminal uses the display function of the communication device through the connection via the wireless LAN. The first terminal and the communication device confirm whether the permission is to be continued or terminated. In response to a termination of the permission, the communication device terminates the connection with the second terminal via the wireless LAN to make the second terminal unable to use the display function.
