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: 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: 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.

Abstract: A method and apparatus for performing multimedia broadcast multicast service (MBMS) minimization of drive test (MDT) in a wireless communication system is provided. A user equipment (UE) receives a MBMS-MDT timer configuration from a network. A MBMS-MDT timer is newly defined for the MBMS-MDT. The UE starts the MBMS-MDT timer based on the received MBMS-MDT timer configuration when a specific condition, which relates to degradation of quality of MBMS, is met, and while the MBMS-MDT timer is running, the UE performs the MBMS-MDT.

Abstract: A method and apparatus for applying assistance information for traffic steering between a 3rd generation partnership project (3GPP) access network and a non-3GPP access network in a wireless communication system is provided. A user equipment (UE) receives assistance information for traffic steering through a dedicated signaling from an eNodeB (eNB), and starts a timer upon entering an idle mode. The UE applies the assistance information received through the dedicated signaling until the timer expires. After the timer expires, the UE applies assistance information received through a broadcast signaling.

Abstract: Radio link Failure (RLF) reporting operation in a wireless communication system using multiple cells is disclosed. According to this operation, when a first cell and a second cell are simultaneously connected to a UE and the first cell and the second cell are of different base stations (a first base station and a second base station respectively), if the RLF with the UE on the first cell is detected by the first base station, the first base station may transmits an indication of the RLF with the UE on the first cell to the second base station.
