A communication transfer apparatus and a communication transfer method can transfer communications at low cost without the need of requesting a global IP network to switch any port number. The local internet protocol address of the origin terminal of transfer described in a record relating to a transfer out of the records of the masquerade table that is utilized for an internet protocol masquerade is rewritten as the local internal protocol address of the destination terminal of transfer, while maintaining the global port number of the record.

In the QoS control system of the wireless LAN network including the wireless LAN access points, and the wireless LAN terminals to be connected thereto, the wireless LAN access point authenticates the user on the basis of the recorded user's authentication information when the user carries out the authentication request from the wireless LAN terminal. The wireless LAN access point is connected to the servers to notify the wireless LAN access point of the information for identifying the wireless LAN terminal and the recorded user's QoS service content through the communication network. The wireless LAN access point and the wireless LAN terminal carry out the priority control in accordance with the priority information of the QoS service from the server. Even when the terminal to be used is changed, if the same user logs onto the certificate server by using the same authentication information, the same QoS service can be offered consistently.
