1. A method for supporting handover, by a first evolved node b (eNB) included in a source cell, in a communication system, comprising:
- transmitting, to a user equipment (UE), information indicating that a public land mobile network (PLMN) authorized for the UE is changed;
receiving, from the UE, a measurement report including PLMN identifiers (IDs) broadcasted by a target cell, the PLMN IDs being IDs of PLMNs available in the target cell;
determining a target PLMN for the UE from among the PLMNs, based on the measurement report; and
transmitting, to the UE, information for the determined target PLMN.

Abstract
The present invention discloses a method for supporting a handover to a closed subscriber group (CSG) cell or a hybrid cell in a mobile communication system, and the method includes: sending, by a radio access network (RAN), information indicating that authorized public land mobile network (PLMN) information changes to a user equipment (UE); sending, by the UE, all PLMN identifiers (IDs) broadcasted by a target CSG cell to a source RAN in a measurement report; and selecting, by the source RAN or a source core network(CN), a target PLMN for the UE.
