Abstract:
A method and apparatus for controlling inter-PLMN handover based on CSG lists of equivalent PLMNs is provided. A method for receiving subscriber information of a terminal at a Mobility Management Entity (MME) includes transmitting an update location request message for the terminal to a Home Subscriber Server (HSS), and receiving an update location acknowledgement message with the subscriber information of the terminal from the HSS, wherein the update location request message comprises a list of equivalent Public Land Mobile Networks (PLMNs) among which the MME supports inter-PLMN handover of the terminal. The method and apparatus for controlling inter-plan handover to a CSG cell according to the present invention is characterized in that a control apparatus of a core network acquires the allowed CSG lists for determining a User Equipments (UEs) capability of access to a CSG cell and determines whether to permit inter-PLMN handover based on the allowed CSG lists.

Claim (Index 5):
A method by a terminal in a communication system, the method comprising:\n transmitting, to a mobility management entity (MME), an attach request message or a tracking area update request message; and receiving, from the MME, a message related to a handover, wherein an update location request message is transmitted from MME to a home subscriber server (HSS), the update location request message including an equivalent public land mobile network (PLMN) list in case that the MME supports an inter-PLMN handover to a closed subscriber group (CSG) cell in an equivalent PLMN of the equivalent PLMN list, wherein an update location acknowledgement (ACK) message is transmitted from the HSS to the MME, the update location ACK message including CSG subscription information for the equivalent PLMN list, wherein a handover required message related to the handover is transmitted from a base station to the MME, the handover required message including a CSG identity (ID) of a target cell, and wherein a CSG membership of the terminal in the target cell is validated based on a CSG ID list of a target PLMN.
