Abstract: One disclosure of the present specification provides a method for performing congestion control when session management congestion occurs in a network system. The method comprises the steps of: transmitting, to an access and mobility function (AMF) node, a request message requesting access to the network system; and receiving a refusal message rejecting the access request from the AMF node when the session management congestion occurs, wherein upon receiving the refusal message, the request message may not be transmitted again for a predetermined period of time.

Abstract: A method for a user equipment (UE) to perform public land mobile network (PLMN) selection in a wireless communication system, and which includes selecting, by the UE, a first PLMN; in response to the first PLMN not providing direct communication resources, selecting, by the UE, a second PLMN providing direct communication resources; performing, by the UE, a registration on the second PLMN; receiving, by the UE, a failed registration code of “PLMN not allowed” due to a failing of the registration on the second PLMN; and performing, by the UE, the direct communication on the second PLMN in a limited service state. Further, the UE remains on the first PLMN based on a normal service state and the UE does not perform an additional PLMN selection during a duration of the direct communication in the second PLMN based on the limited service state.

Abstract: One disclosure of the present specification provides a method for a control plane (CP) function entity creating a session, the CP function entity being in charge of managing a session in a next-generation mobile communication network. The method may comprise the steps of: receiving a connectivity request message from a terminal if the creation of a session is not included in a process by which the terminal attaches to a core network of the next-generation mobile communication; on the basis of information on the type of service to be provided to the terminal, deciding to create, for the terminal, a session that needs to be always-on, or in other words, always-connected; and transmitting, to the terminal, a connectivity completion message including information indicating the session that needs to be always-on, or in other words, always-connected.

Abstract: A method of controlling a backoff timer at a user equipment (UE) configured for dual priority, the method includes transmitting a non access stratum (NAS) request message without an access point name (APN) including a low priority indicator set to a first value to a network node, wherein the first NAS request message without the APN is an attach request message transmitted along with a packet data network (PDN) connectivity request without the APN; receiving a reject message for the NAS request message from the network node, and wherein a cause in the reject message is set to insufficient resources; setting the low priority indicator to a second value; and initiating a new attach procedure without the APN, while a session management (SM) backoff timer is running, wherein the first value of the low priority indicates that the UE is configured for NAS signaling low priority.

Abstract: A source BS may determine that handover of a UE to a target BS is needed and transmit a handover request message indicating a request of handover to the target BS to a network node to which the source BS is connected. The handover request message may include radio access network (RAN) type information indicating a target RAN and radio access technology (RAT) type information indicating a target RAT.

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.
