Disclosed are: a method for providing continuity of a multimedia broadcast multicast service (MBMS) service, and a device supporting the same. The method may include: entering a radio resource control (RRC) connected state with respect to a first cell; receiving MBMS-related system information from the first cell; determining whether a mobility condition for continuity of an MBMS service is satisfied based on the received system information; and entering an RRC idle state when it is determined that the mobility condition is satisfied, and the UE does not supports a handover operation.
