Abstract: According to an aspect of the present disclosure, there is provided a method of implementing a radio access network (RAN)-core convergence mobile network based on cloud native, the method comprising: extending a first open RAN base station including an open RAN-central unit-control plane (O-CU-CP) and a cloud-based second open RAN base station having converged functions of a core network into a service-based architecture (SBA) of the core network; authenticating and accepting user equipment (UE) through the extended SBA; and extending the UE to the SBA through radio resource setting and protocol data unit (PDU) session establishment.

Abstract: A method for releasing a context of a user equipment in a non-3GPP access network and a network entity performing the same are disclosed. In a case in which the UE is a unreachable state, a non-3GPP interworking function (N3IWF) may a UE context release request message to an access and mobility management function (AMF), and may perform protocol data unit (PDU) session user plane de-activation between the AMF, a session management function (SMF), and a user plane function (UPF). In addition, the AMF may transmit a UE context release command message to the N3IWF, and the N3IWF may transmit a UE context release complete message to the AMF.

Abstract: A non-access stratum based access method and a terminal supporting the same. The terminal receives an Internet protocol (IP) address allocated from a first gateway included in a non-3rd generation partnership project (3GPP) access network. In addition, the terminal applies a non-access stratum (NAS) protocol to a first device managing mobility of the terminal through the IP address.

Abstract: A deregistration method of user equipment in a network and user equipment performing the same is disclosed. The user equipment determines whether the user equipment is in a connection management (CM)_CONNECTED state in a non-3GPP access network and initiates a deregistration procedure through the non-3GPP access network if the user equipment is in the CM_CONNECTED state in the non-3GPP access network.

Abstract: A distributed mobility management method includes: receiving, by a base station, an address resolution protocol (ARP) request message from a user terminal in a heterogeneous unified network environment; generating, by the base station, a logical interface having a media access control (MAC) proxy of the base station as a link address; registering, by the base station, the logical interface with an edge unified control entity; and transmitting, by the base station, an ARP response message including the MAC proxy that the logical interface has to the user terminal.

Abstract: A signaling method in a mobile communication core network and a system thereof. The signaling method in a mobile communication core network includes: receiving, by a traffic controller, an initial attach request from a terminal in a software defined network (SDN) based mobile communication core network; allocating, by the traffic controller, a tunnel identifier for a tunnel establishment between a base station and a traffic transmitter or between traffic transmitters in response to the initial attach or a service request of the terminal; and transmitting, by the traffic controller, the allocated tunnel identifier to the traffic transmitter and the base station.

Abstract: A method for notifying downlink data in a network, a network triggered service request method, and a network entity performing the same. The method includes receiving, by an access and mobility management function (AMF), a message including a packet data unit (PDU) session identifier (ID) from a session management function (SMF), confirming, by the AMF, a state of user equipment (UE) associated with the PDU session ID, and transmitting, by the AMF, a non-access stratum (NAS) notification message to the UE through a non-3GPP access if the UE is in a connection management (CM)_IDLE state in 3GPP access and in a CM_CONNECTED state in the non-3GPP access.
