AUTHENTICATION SYSTEM, SMALL-SIZED BASE STATION AND AUTHENTICATION METHOD

WIPO Patent Application WO/2010/058847

A1

An authentication system, small-sized base station and authentication method for ensuring that an authentication as to whether the installed position of a small-sized base station is proper or not can be performed at a server-side.  A packet transmitted, as an authentication request, by a femto base station (1) contains the IC intra-card information of an IC card inserted in the femto base station (1).  At a circuit terminating equipment (2), a local IP address described in the header of the packet is converted to a global IP address for transmission to a femto line concentrator (4).  At the femto line concentrator (4), the IC intra-card information is associated with the global IP address, thereby producing authenticating information, which is then transmitted to an authentication server (5).  At the authentication server (5), if the IC intra-card information and global IP address contained in the authenticating information have been registered with an authentication table in such a manner that the IC intra-card information is associated with the global IP address, then it is determined that the installed position of the femto base station (1) is proper.  This invention is applicable to a femto-cell base station.
