Abstract: Provided is a method for a base station performing a multimedia broadcast multicast service (MBMS) session update in a wireless communication system, and a device supporting same. The base station may comprise: receiving, from a multi-cell coordination entity (MCE), a MBMS session update request message comprising a single-cell point-to-multipoint (SCPTM) transmission stop indication; and transmitting, to the MCE, a MBMS session update response message as a response to the MBMS session update request message.

Abstract: Provided are a method by which a base station controls the access of a terminal, and a device for supporting the same. The method comprises the steps of: receiving, from a core network, information on an RRC connection procedure in which access in an RRC inactive state is restricted; receiving a request for executing the RRC connection procedure from a terminal which is in the RRC inactive state; and transmitting, to the terminal, a message notifying that the requested execution of the RRC connection procedure has been restricted, when the RRC connection procedure requested from the terminal corresponds to the RRC connection procedure in which the access is restricted.

Abstract: Provided are a method for a base station to support single-cell point-to-multipoint (SCPTM) service continuity in a wireless communication system, and an apparatus supporting the same. The method may comprise the following steps performed by the base station: receiving, from a multi-cell coordination entity (MCE), an MBMS session start request message comprising a cell ID list; checking whether a requested MBMS resource is established; and transmitting, to a neighboring base station, MBMS bearer service information on a cell basis.

Abstract: A method and apparatus for transmitting location information of a serving small cell in a wireless communication system is provided. A first evolved NodeB (eNB), which may be a master eNB (MeNB) in dual connectivity, receives the location information of the serving small cell served by a second eNB, which may be a secondary eNB (SeNB) in dual connectivity, from the second eNB, and transmits the received location information of the serving small cell to a mobility management entity (MME).

Abstract: Provided are a method and an apparatus for transmitting a maximum stratum level in a wireless communication system. An evolved NodeB (eNB) or a home eNB (HeNB) having a global positioning system (GPS) constitutes a maximum stratum level indicating a maximum value of a hop capable of supporting radio interface based synchronization (RIBS) and transmits the constituted maximum stratum level to a small cell. Meanwhile, the small cell determines whether a stratum level is greater than the maximum stratum level, and transmits the maximum stratum level to the eNB or the HeNB having the GPS when the stratum level is greater than the maximum stratum level.

Abstract: A method and apparatus for supporting a local gateway (L-GW) service in a wireless communication system is provided. When an L-GW is co-located with a master evolved NodeB (MeNB) in dual connectivity, a secondary evolved NodeB (SeNB) in dual connectivity receives a request message including information on a specific E-UTRAN radio access bearer (E-RAB), which is served by a L-GW, from a master evolved NodeB (MeNB) in dual connectivity which has the L-GW, decides to transmit data via a X2 interface instead of a S1-U interface for the specific E-RAB, and transmits a response message to the MeNB.

Abstract: In an inter-master eNB (MeNB) handover procedure without secondary eNB (SeNB) change, a user equipment (UE) receives a SeNB kept indicator indicating that a SeNB has been kept successfully from a source MeNB. Upon receiving the SeNB kept indicator, the UE determines that the SeNB has been kept successfully in the inter-MeNB handover without SeNB change, and skips the random access procedure to the SeNB.
