Abstract
A femto base station of a WiMAX system can manage a list of closed subscriber groups (CSGs). A CSG indicator is broadcast. The femto base station receives a registration request message from a mobile station having received the CSG indicator and adds the mobile station to a CSG registration list. The femto base station searches for the mobile station from the CSG registration list if an attach request message is received; and forwards the attach request message to an access service network (ASN) gateway if the mobile station is in the CSG registration list. The femto base station establishes a link message with the mobile station if an attach acceptance message corresponding to the attach request message from the ASN-gateway.
