Abstract: A method and apparatus for transmitting a paging message in a cloud radio access network (RAN) system is provided. A baseband unit (BBU) or a mobility management entity (MME) determines a location update range of a user equipment (UE) based on moving speed and a moving direction of the UE, and transmits information this to the UE. The UE transmits information on moving information of the UE, which is determined based on the received information and a measurement result with respect to at least one accessible remote radio frequency (RF) unit (RRU) of the UE, and the measurement result to the BBU or the MME; and The BBU or MME updates the location update range of the UE based on the received measurement result and the moving information of the UE, and transmits a paging message to the UE through at least one RRU included in the updated location update range of the UE.
