Abstract: Provided are an operation method of a terminal in a wireless communication system and a terminal using the method. The method comprises: transmitting a radio resource control (RRC) connection request message; receiving an RRC connection setup message in response to the RRC connection request message; and transmitting an RRC connection setup complete message in response to the RRC connection setup message, wherein the RRC connection request message uses the same RRC connection establishment cause value for a first call and a second call, and the RRC connection setup message comprises an indicator which can distinguish the first call from the second call.

Abstract: 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.

Abstract: For continuous data transmission during a handover procedure, Make-Before-Break handover may be introduced, which maintains source evolved NodeB (eNB) connection after reception of radio resource control (RRC) message for handover. In order to reduce ambiguity of Make-Before-Break handover, the present invention provides receiving a handover command from a network, after receiving the handover command from the network, keeping exchanging data with a source cell, stopping exchanging data with the source cell when a condition is met, and after stopping exchanging data with the source cell, starting exchanging data with a target cell.

Abstract: Provided are a method of measuring by using a terminal in a wireless communication system, and a device supporting same. The terminal may: measure on the basis of a reference signal; receive a reference signal flag from a network; and derive a new measurement result on the basis on the received reference signal flag. The reference signal flag issues instructions as to whether a reference signal is sent from a target subframe, and the target subframe is a subframe used to derive the new measurement result.

Abstract: Provided is a method for denying transmission by a terminal in a wireless communication system. A terminal may receive an effective period and a threshold value, count the number of autonomous denial subframes during the effective period, and deny transmission in a current subframe if the counted number of the autonomous denial subframes is less than the threshold value.

Abstract: A method and apparatus for performing multimedia broadcast multicast service (MBMS) minimization of drive test (MDT) in a wireless communication system is provided. Upon receiving a MBMS-MDT configuration from a network, a user equipment (UE) selects a subset of multicast broadcast single frequency network (MBSFN) areas among multiple MBSFN areas providing interested MBMS services, and performs MBMS-MDT only for the selected subset of MBSFN areas. The subset of MBSFN areas may be selected based on priorities of the multiple MBSFN areas.
