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: 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: The present description discloses a method for performing network selection and traffic routing by a mobility management entity (MME). The method comprises the steps of: if a request for a public data network (PDN) connection is received from a user equipment (UE), an MME deciding whether or not the PDN connection is to be offloaded to a wireless local area network (WLAN) on the basis of an indication for WLAN offloadability obtained from a home subscriber server (HSS); the MME transmitting to the UE a message comprising information about a network-based IP flow mobility (NBIFOM) function and the decision result with respect to the PDN connection; and the MME transmitting the decision result with respect to the PDN connection to a PDN gateway (P-GW) and/or a policy and charging rules function (PCRF), wherein the decision result with respect to the PDN connection and the information about the NBIFOM function can be used for triggering any one of the UE, P-GW and PCRF such that the NBIFOM function is suspended or resumed.
