Method and apparatus for controlling inter-PLMN handover to CSG cell

摘要

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.

主权项

1. A method for communication by a mobility management entity (MME), the method comprising:
receiving a first request message from a base station; transmitting, to a home subscriber server (HSS), a second request message including an equivalent public land mobile network (PLMN) list, if the MME supports an inter-PLMN handover to a closed subscriber group (CSG) cell in the equivalent PLMN list; and receiving, from the HSS, a response message in response to the second request message, the response message including CSG subscription information for the equivalent PLMN list.
