    Abstract: Provided are a method for performing paging by a mobility management entity (MME) in a wireless communication system and an apparatus for supporting the same. The MME comprises: receiving an nB from a base station; calculating a paging frame (PF) on the basis of the nB; and transmitting a paging message to the base station on the basis of a paging hyperframe (PH) and the calculated PF, wherein the PH may indicate a number of a hyper system frame in which the paging message is to be transmitted, and the PH may indicate a number of a system frame in which the paging message is to be transmitted.

    Abstract: As one aspect of mobility enhancement of 3rd generation partnership project (3GPP) long-term evolution (LTE)-wireless local area network (WLAN) aggregation, inter-eNodeB (eNB) handover without WLAN termination (WT) change is considered. A source eNB transmits a handover request message including a WT identifier (ID) and WT XwAP ID to a target eNB. The target eNB transmits a WT addition request message including the WT XwAP ID to a WT, and receives a WT addition request acknowledge message from the WT. The target eNB transmits a handover request acknowledge message indicating that a WT is kept to the source eNB. The source eNB transmits a WT release request message indicating that the WT is kept to the WT. The WT is a logical node that terminates a Xw interface on a WLAN.

    Abstract: A method and apparatus for handling evolved universal terrestrial radio access network (E-UTRAN) radio access bearer (E-RAB) switch failure for dual connectivity in a wireless communication system is provided. A master evolved NodeB (MeNB) in dual connectivity receives an E-RAB modification confirm message including a list of E-RABs failed to be modified from a mobility management entity (MME). The MeNB may keep old general packet ratio service (GPRS) tunneling protocol (GTP) tunnels for the failed E-RABs, and trigger a secondary eNB (SeNB) release procedure or a SeNB modification procedure for releasing the failed E-RABs. Alternatively, the MeNB may trigger an E-RAB release procedure for releasing the failed E-RABs.

    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.
