Abstract: The disclosure relates to a communication method and a system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as a smart home, a smart building, a smart city, a smart car, a connected car, healthcare, digital education, a smart retail, security and safety services. A method for a user equipment (UE) in a network is provided. The method includes determining one or more of a mode of the UE, a type of data required, and a service requested, and setting a UE behavior for initiating a NAS procedure based on one or more of the mode of the UE, the type of data required, and the service requested.

Abstract: The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by an access and mobility management function (AMF) in a public land mobile network (PLMN) providing disaster roaming service is provided. The method includes determining whether a disaster condition has ended in a previous PLMN associated with a user equipment (UE) which is registered for the disaster roaming service, in response to determining that the disaster condition has ended and the UE has an emergency protocol data unit (PDU) session, generating a message indicating that the UE is registered for emergency service, and transmitting, to the UE, the message.

Abstract: There is disclosed a method, for a UE, for performing a Network Slice-Specific Authentication and Authorization (NSSAA) procedure in a network comprising the UE and a first network entity. The method comprises: in response to transmitting, to the first network entity, a first message for initiating a first procedure, receiving, from the first network entity, a second message; determining whether a first condition is satisfied, the first condition comprising: the second message includes a predefined indication; and determining whether to block or restrict one or more second procedures based on the first condition.

Abstract: The disclosure relates to 5th generation (5G) and/or 6th generation (6G) communication system for supporting a higher data transmission rate. A method is provided of operating a user equipment (UE) with multi universal subscriber identity module (M-USIM) capability in a wireless communication system. The method includes performing a registration procedure with respect to a connected telecommunication network if the UE is in a non-allowed area and encounters or receives a trigger for a network access stratum (NAS) procedure related to an M-USIM feature.

Abstract: The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method for handling a Non access stratum (NAS) procedure (e.g., service request (SR) procedure or the like) by a user equipment (UE) in a wireless network is provided. The method includes triggering the SR procedure and determining a transmission failure of the SR or a control plane service request message in response to triggering the SR procedure. Further, the method includes determining whether the SR procedure is triggered for a reason comprising one of requesting the wireless network to release a NAS signaling connection, and rejecting a paging request from the wireless network, or requesting the wireless network to release the NAS signaling connection. Further, the method includes performing one of aborting the SR procedure triggered due to the reason in response to determining the transmission failure, or re-triggering the SR procedure triggered not due to the reason in response to determining the transmission failure.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed is a method performed by a UE, the method comprising: having at least one existing PDU session associated with an S-NSSAI; requesting, from an upper layer, a new PDU session; determining a condition; performing checking operations comprising: (i) checking whether allowed NSSAI includes only one S-NSSAI, and (ii) checking whether any of the at least one existing PDU sessions have an attribute which matches a corresponding attribute in the requested new PDU session; and when both checking operations (i) and (ii) are true: selecting a PDU session from the at least one existing PDU sessions which matches at least one attribute, determining that the selected PDU session can be used or associated with the request from the upper layer, and forwarding details of the selected PDU session to the upper layer.
