METHOD OF SELECTING PUBLIC LAND MOBILE NETWORK FOR NETWORK SHARING

摘要

The present invention relates to a method of selecting a public land mobile network (PLMN) for network sharing, and a method of communicating at a base station according to one embodiment of the present invention may include: receiving from a core network a handover request message including information on whether to support network sharing of user equipment (UE); selecting a PLMN identification (ID) by using information on whether to support network sharing of the UE; and transmitting the selected PLMN ID to the UE. According to one embodiment of the present invention, since a source base station, a target base station or a core network node may select a correct PLMN depending on the situation of UE when carrying out a handover, it is possible to decrease unnecessary signaling and errors in a network sharing situation.
