Abstract
The present invention relates to an authentication system, a small base station, and an authentication method which allow a server side to authenticate whether an installation position of a small base station is valid or not. In a packet to be sent as an authentication request from the femto base station 1, in-IC card information of an IC card inserted into the femto base station 1 is contained. A network terminating device 2 converts a local IP address described in a header of the packet to a global IP address, and sends it to a femto concentrator 4. The femto concentrator 4 generates authentication information by associating the in-IC card information with the global IP address, and sends it to an authentication server 5. The authentication server 5 determines that the installation position of the femto base station 1 is valid if the in-IC card information and global IP address included in the authentication information have been associated with each other and registered in an authentication table. The present invention can be applied to a base station for a femtocell.
