Abstract: A communication apparatus is provided that includes: a receiving unit that receives communication parameter for connecting to a first base station via a second base station; a connecting unit that connects to the first base station based on the received communication parameter; and an authentication unit that performs authenticated process with the first base station based on the received communication parameter.

Abstract: When connecting a wireless LAN terminal to a specific wireless access point, an inquiry is made to a server about the specific wireless access point, via the wireless access point which the wireless LAN terminal is connecting to, and then connection information for connecting to the specific wireless access point is automatically received, whereby wireless communication are established between the wireless LAN terminal and the specific wireless access point. Furthermore, in a case where wireless LAN terminals which are permitted to connect are registered into each wireless access point, when a wireless access point receives a connection request from a wireless LAN terminal that is not permitted to connect, an inquiry is made to another wireless access point regarding whether there is a wireless access point which that wireless LAN terminal is permitted to connect to.

Abstract: A data relay apparatus is connected to a network having a DHCP server and an authentication server. The data relay apparatus stores a MAC address of a communication device permitted to connect to it. When a communication device attempts to connect to the data relay apparatus, it is determined whether a MAC address of the communication device is stored in the data relay apparatus. If the MAC address is stored, the communication device is not authenticated by the authentication server, instead, dummy data indicating that authentication is successful is transmitted to the communication device. If the communication device requests that the DHCP server assign it an IP address, the DHCP server assigns an IP address to the communication device. Different security levels are set for a communication device that has failed to authenticate to the authentication server and for a communication device that successfully authenticates to the authentication server.

Abstract: A data relay apparatus (access point) connects to a network having a DHCP server and authentication server. The data relay apparatus stores the MAC address of a communication device which is permitted to connect. When a communication device starts to connect to the data relay apparatus, it is determined whether or not the MAC address of the communication device is stored. Assume that the address is stored. In this case, even if, for example, the communication device is not authenticated by authentication processing performed by the authentication server, dummy data indicating that authentication is successful is transmitted to the communication device to notify the communication device that the authentication is successful. Subsequently, since the communication device requests the DHCP server to assign an IP address, the address assignment request from the communication device is transferred to the DHCP server so as to assign the IP address to the communication device.
