    Abstract: A method for a user equipment (UE) connecting to a network includes: if second connection is to be executed by means of a second access, determining whether or not first connection has been previously executed by means of a first access; and, if the first connection by means of the first access has been executed and the second connection by means of the second access is determined to be an addition, transmitting a connection request message comprising identification information of a control plane (CP) function node. The identification information of the control plane (CP) function node could have been obtained during the first connection by means of the first access. Both the first connection by means of the first access and the second connection by means of the second access can be managed by means of the control plane (CP) function node.

    Abstract: Provided in one disclosure of the present specification is a method for a wireless device attempting network access. The method may comprise the steps of: an RRC layer of the wireless device receiving, from a cell, a first piece of information relating to an NB-IoT RAT; and an NAS layer in the wireless device determining whether to initiate an NAS signaling process even when a backoff timer is running, wherein the backoff timer may be running due to previously having received a rejection message, and wherein when the wireless device uses an NB-IoT RAT and when the NAS signaling process is for transmitting exception data, it may be determined to initiate the NAS signaling process even though the backoff timer is running. The method may further comprise a step of the NAS layer in the wireless device setting an RRC establishment cause of an RRC connection request message as mobile originating (MO) exception data.

    Abstract: A method for transmitting, by a first mobility management entity (MME), a group message in group units, to which a plurality of terminals belong, in a wireless communication system according to one embodiment of the present invention may comprise the steps of: receiving a group message request message requesting for transmission of the group message, wherein the group message request message includes a group identifier (ID) of a group to receive the group message, delivery contents to be transmitted to the group, and validity time which buffers the delivery contents; detecting a first terminal connected to the first MME within the validity time; confirming whether the group ID of the detected first terminal is identical to the group ID of the group message request message; and, if the two group IDs are identical, transmitting the delivery contents to the first terminal.

    IPC: H04W72/10

    Abstract: User equipment may send a channel allocation request (hereinafter referred to as a first channel allocation request) to a network for transmission of data. When the transmission of data has backed off, the user equipment may send a channel allocation request (hereinafter referred to as a second channel allocation request) again for the transmission of data. At this time, the second channel allocation request may be transmitted to the network together with a priority raise request if a remaining timeframe Tremain of an upper timeframe T is smaller than a certain guard time.

    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.
