Abstract: Disclosed is a session management method based on protocol data unit (PDU) session anchor (PSA) relocation, and an device performing the session management method. The session management method may include determining to perform PSA relocation, establishing a new PSA device through the PSA relocation, and releasing an existing PSA device, in which the PSA relocation may allow traffic moving towards the existing PSA device to move to the new PSA device.

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: Provided is a location reporting method including sending, by an access and mobility management function (AMF) device, a location reporting control message requesting a location of a user equipment (UE) to an access network; and receiving, by the AMF device, a location report message from the access network in response to the location reporting control message. The location reporting control message may include requested location information or a reporting type.

Abstract: Provided is a network triggered service request method performed by an access and mobility management function (AMF) device, the method including receiving a Namf_Communication_N1N2MessageTransfer message from a session management function (SMF) device that receives a data notification message indicating that a user plane function (UPF) device receives downlink data for a protocol data unit (PDU) session and no access network tunnel information is stored for the PDU session; and sending, to an access network, a paging message for a PDU session between the AMF device and a user equipment (UE) based on a PDU session identifier (ID) included in the Namf_Communication_N1N2MessageTransfer message. The UE receiving the paging message from the access network is configured to initiate a service request procedure according to a connection management state of the UE.

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.

Abstract: Provided is a communication method and apparatus based on access network paging and core network paging. A communication method performed by an anchor radio access network (RAN) receives a signaling message or a data packet for a user equipment (UE) from a core network, triggers paging for the UE, and transmits a paging request to the core network in response to a failure of the paging. The core network is configured to transmit a core network (CN) assisted paging request message to a new RAN within a determined target paging area in response to the paging request, and the new RAN is configured to perform the paging for the UE based on the CN assisted paging request message.
