Abstract: Provided are a method of managing UE context and a device supporting the method. According to one embodiment of the present invention, a method for managing UE context in a wireless communication system includes: receiving a UE context request message including a radio resource control (RRC) establishment cause from a second BS, wherein the first BS and the second BS are located in a same radio access network (RAN)-based notification area (RNA); and when the RRC establishment cause is related to RNA update, transmitting a UE context response message to the second BS, wherein the UE context response message piggybacks a RRC message requesting a UE to move to a RRC inactive state.

Abstract: Provided are: a method by which a central unit (CU) of a base station updates access control barring (ACB)-related parameters in a wireless communication system; and an apparatus for supporting the same. The method comprises the steps of: receiving information indicating a change in the ACB-related parameters; updating the ACB-related parameters based on the received information; and transmitting the updated ACB-related parameters to a distributed unit (DU) of the base station.

Abstract: Provided are a method for modifying, by a central unit (CU) of a base station (BS), a QoS flow to DRB mapping rule in a wireless communication system, and an apparatus supporting the same. The method may include: modifying the QoS flow to DRB mapping rule; determining whether or not the modified QoS flow to DRB mapping rule is related to reflective mapping; and when it is determined that the modified QoS flow to DRB mapping rule is not related to the reflective mapping, transmitting the modified QoS flow to DRB mapping rule to a user equipment (UE).

Abstract: When a user equipment (UE) requests a service simultaneously during a mobility management (MM) attach procedure in a new radio access technology (NR; or new RAT) system, slice related information may be transmitted together. In detail, a radio access network (RAN) node receives a network connection request, a service request and slice related information from the UE, and routes the network connection request, the service request to a dedicate common control plane function (C-CPF) according to the slice related information.

Abstract: For supporting selection/authorization of network slicing, a radio access network (RAN) node in a new radio access technology (RAT), e.g. gNB, receives a service request including slice information from a user equipment (UE), and determines a slice based on the slice information. The RAN node forwards the service request including the slice information to a common control plane function (C-CPF), and then, the C-CPF checks whether the UE is authorized for a specific slice. The RAN node receives a service response including an authorization indication for the specific slice from the C-CPF, and performs a corresponding action for the specific slice.

Abstract: A method and apparatus for handling multiple connectivity in a wireless communication system. A first SN receives, from a master node (MN), a SN addition request message including (1) information informing that a multiple connectivity service for a specific UE is initiated, and (2) information on a suggested number and a maximum number of connections for the specific UE. A first SN determines a number of connections for the multiple connectivity service, based on the information on the suggested number and the maximum number. A first SN transmits, to the MN, an SN addition Request Acknowledge message including the determined number of connections.
