Abstract: A disclosure of the present specification provides a packet data network (PDN) connection management method performed by packet data network gateway (P-GW). The method may comprise the steps of: establishing a first type PDN connection with a user equipment (UE); recognizing that an error has occurred in the first type PDN connection, after establishing the first type-PDN connection; and transmitting a delete bearer request message to a mobility management entity (MME) in order to perform a bearer de-activation procedure according to the recognition of the error occurrence. The delete bearer request message may include information indirectly indicating that an error has occurred in the first type PDN connection.

Abstract: A method for transmitting and receiving a group messaging in a wireless communication system and an apparatus for the same is disclosed. Particularly, the method for receiving a group message performed by a user equipment (UE) in a wireless communication system include receiving assistance information indicating whether a paging message is transmitted for each UE group from a network node, receiving the paging message from the network node on a paging occasion of the UE, when the transmission of the paging message for a group to which the UE is belonged in indicated by the assistance information, and receiving the group message, when a group message transmission for the group to which the UE is belonged is activated by the paging message.

Abstract: Disclosed herein are a method and apparatus for monitoring UE reachability in a wireless communication system. A method for monitoring UE reachability may include receiving, by a Mobility Management Entity, a monitoring request message for UE reachability including a maximum response time from a Home Subscriber Server, detecting, by the MME, the UE reachability if it is expected that paging is able to be transmitted to UE when extended Discontinuous Reception is applied to the UE, and sending, by the MME, a UE reachability notification to a Service Capability Exposure Function before a next paging occasion of the UE, wherein the maximum response time may indicate a time during which the UE maintains a reachable state so that downlink data is reliably delivered to the UE, and wherein an occasion when the UE reachability notification is transmitted may be determined by taking into consideration the maximum response time.

Abstract: Provided is a method for handling a packet data unit (PDU) session establishment procedure. The method may performed by an access and mobility management function (AMF) node and comprise: determining whether to reject a PDU session establishment request. The determination may be performed if the PDU session establishment request includes an existing PDU session identifier. Based on the existing PDU session identifier, an identifier of a session management function (SMF) node may be acquired. The PDU session establishment request may be accepted, if it is determined based the identifier of the SMF node that the SMF node and the AMF node belong to a same PLMN. The PDU session establishment request may be further accepted, if it is determined based the identifier of the SMF node that the SMF node belongs to a HPLMN. The PDU session establishment request may be rejected, if it is determined based the identifier of the SMF node that the SMF node and the AMF node do not belong to the same PLMN or the SMF node does not belong to the HPLMN.

Abstract: Disclosed are a method for cell granularity reporting in a wireless communication system and a device therefor. The method for performing cell granularity reporting by a user equipment (UE) in an idle state in a wireless communication system includes receiving a cell granularity reporting configuration from a network, detecting whether a cell in which the UE is camping in the idle state is changed, and when it is detected that the cell in which the UE is camping is changed, transmitting cell change information to the network, wherein the cell granularity reporting configuration includes an indication regarding whether to receive a multimedia broadcast and multicast service (MBMS), and when the indication regarding whether an MBMS is received is activated, the UE does not perform the cell granularity reporting unless the UE receives MBMS data.
