SERVER IN CHARGE OF CONTROL PLANE IN MOBILE COMMUNICATION NETWORK, AND METHOD FOR CONTROLLING ACCESS

摘要

The present invention provides a method for controlling an access in a server in charge of a control plane in a visited network. The method for controlling the access comprises the step of the server in charge receiving from a Home (e)NodeB an access request message or an update request message by a roaming terminal. The Home (e)NodeB can be operated as a closed subscriber group (CSG) or in a mixed access mode. The access control method further comprises the steps of: assessing whether a disagreement exists between the CSG related information in subscriber information of the roaming terminal obtained from a subscriber information server located in the home network of the roaming terminal, and the local CSG related information defined in the visited network; when a disagreement is found, controlling the access using priority information previously defined by the server in charge; and the server in charge transmitting to Home (e)NodeB an acceptance message or a denial message for the access of the update request message, according to the access control.
