Abstract
In a communication system 301, a wireless base station device 111 transmits inquiry information for acquiring an address of an internal network connection device 102 to a communication management device 103. The communication management device 103 receives the inquiry information, and transmits response information indicating the address of the internal network connection device 102 to the wireless base station device 111. The wireless base station device 111 includes the address of the internal network connection device 102 indicated by the response information received from the communication management device 103, in access request information indicating a request for access to an internal network 51 by a wireless terminal device 150, and transmits the access request information to the communication management device 103.
