METHOD FOR PROVIDING LOCAL CSG AND CONTROLLING ACCESS IN SERVER IN CHARGE OF CONTROL PLANE IN MOBILE COMMUNICATION NETWORK

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 request message or the update request message can include one or more of local CSG related information defined in the visited network or CSG related information in a home network. 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.
