Abstract: The present invention relates to a method and an apparatus for determining a path switch in a wireless communication system. Specifically, the present invention relates to a method for determining a path switch of a first network entity, the method comprising the steps of: receiving bearer setup information including a bearer type regarding at least one bearer; transmitting a path switch request to a second network entity on the basis of the bearer setup information; receiving a path switch response corresponding to the path switch request from the second network entity; and determining a path switch depending on whether the path switch response indicates admission of a default bearer.

Abstract: A method and apparatus for obtaining radio access network (RAN) sharing information in a wireless communication system is provided. For an overload procedure, an evolved NodeB (eNB), which is shared by a plurality of operators, receives an indication of overloaded operator from a mobility management entity (MME), and performs an overload action for the overloaded operator indicated by the indication. Further, for a load balancing procedure, a first eNB, which is shared by a plurality of operators, receives a status report per operator from a second eNB, which is shared by the plurality of operators, and performs a load balancing action based on the status report.

Abstract: A method and apparatus for performing access control and/or membership verification for dual connectivity in a wireless communication system is provided. A first evolved NodeB (eNB) transmits a closed subscriber group (CSG) membership status of a user equipment (UE) to a second eNB, which is a home eNB (HeNB), and receives at least one of a CSG identifier (ID) or a cell access mode of the second eNB from the second eNB. A mobility management entity (MME) may verify the CSG membership status of the UE and transmit the verified CSG membership status of the UE to the first eNB. And then, the first eNB transmits the verified CSG membership status of the UE to the second eNB.

Abstract: The present invention relates to a method and a device for performing cell shaping. A base station can establish a cell shaping plan on the basis of current states. The current states may be the load of the base station and the traffic space distribution of the base station. The base station transmits a first message to a neighboring base station and receives a second message from the neighboring base station in response to the first message. The first message may include the cell shaping plan, and the second message may include whether or not the neighboring base station can perform cell shaping. The base station can determine whether or not to perform cell shaping on the basis of the second message.

Abstract: A method and apparatus for transmitting a handover report message in a wireless communication system is provided. In a heterogeneous network (HetNet) intra long term evolution (LTE) failure case, an eNodeB (eNB) performs a handover procedure for a user equipment (UE) with a source eNB, and receives a radio link failure (RLF) indication message. The eNB transmits a handover report message to the source eNB, the handover report message including UE history information element (IE) of the UE.

Abstract: A method for determining a radio resource control (RRC) configuration in a wireless communication system supporting dual connectivity, and an apparatus supporting the same is disclosed. The method for determining, by a base station (BS), a radio resource control (RRC) configuration in a wireless communication system supporting dual connectivity, includes transmitting, by a first BS, a first RRC configuration of a serving cell of the first BS or remained user equipment (UE) capability to a second BS configured in a UE, and receiving, by the first BS, a second RRC configuration of a serving cell of the second BS configured in the UE from the second BS. The first BS and the second BS are involved in dual connectivity for the UE, and the second RRC configuration is determined by the second BS based on the first RRC configuration or the remained UE capability.

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.
