Abstract: A method and apparatus for resuming only signaling radio bearers (SRBs) in a wireless communication system is provided. A wireless device triggers a signaling while the wireless device is in a radio resource control (RRC) inactive state, and resumes only SRB and transmits a message 3 (MSG3) of a random access procedure to a network when an early data transmission (EDT) triggering condition for transmission via the MSG3 is fulfilled. The MSG3 includes the signaling.

Abstract: The present specification provides a method for performing a radio link failure (RLF) recovery procedure in a wireless communication system.
The method performed by a first user equipment (UE) includes, wherein the first UE is connected to a base station via a UE-to-UMTS (Uu) link and is connected to a second UE via a sidelink, determining a path for performing the RLF recovery procedure when a RLF is detected on the Uu link, and performing an RRC connection re-establishment procedure in order to recover the RLF through the determined path.

Abstract: A method for transmitting, by user equipment, a PDU session establishment request includes: receiving a session management message based on an SSC mode from an SMF through an AMF in a state in which a back-off timer associated with a DNN-based congestion control is in operation, wherein the session management message is associated with a DNN to which the DNN based congestion control is applied; and transmitting a PDU session establishment request to the AMF for establishment of a new PDU session associated with the DNN on the basis of the session management message. The PDU session establishment request includes information for preventing rejection of the PDU session establishment request, and the information for preventing the rejection may be used to make the AMF ignore the DNN-based congestion control and transmit the PDU session establishment request to the SMF associated with the new PDU session.

Abstract: A method for moving user equipment (UE) from a next generation system (NGS) to an evolved packet system (EPS) in a wireless communication system comprises: by the UE, a step of determining to move to the EPS; and a step of transmitting a radio resource control (RRC) connection request and an attach request to the EPS. In the method for moving from the NGS to the EPS, if the UE has an ongoing voice call when determining to move to the EPS, the UE maintains the ongoing voice call by performing at least one of an access class barring (ACB) execution or a transmission of ongoing voice call related information by using “ongoing voice call” call type information.
