    Abstract: The present disclosure may be related to a pre-5G or 5G communication system to be provided for supporting higher data rates Beyond 4G communication system such as LTE. A method, for a UE in a network comprising the UE and an AMF entity, is disclosed. The method comprises: transmitting, to the AMF, a control plane service request (CPSR) message comprising data of a first type, receiving, from the AMF, a security mode command message indicating that an integrity check related to the CPSR message has failed, in response to receiving the security mode command message, identifying whether the CPSR message comprises the data of the first type including data of a second type, or the CPSR message comprises the data of the first type excluding the data of the second type, and transmitting the CPSR message excluding the data of the first type except the data of the second type.

    Abstract: The present disclosure may be related to a pre-5G or 5G communication system to be provided for supporting higher data rates Beyond 4G communication system such as LTE. A method, for a UE in a network comprising the UE and an AMF entity, is disclosed. The method comprises: identifying that the UE in idle mode, has an emergency protocol data unit (PDU) session, transmitting, to the AMF, a control plane service request (CPSR) message comprising data of a first type, receiving, from the AMF, a security mode command message indicating that an integrity check related to the CPSR message has failed, in response to receiving the security mode command message, identifying whether the CPSR message comprises the data of the first type including data of a second type, or the CPSR message comprises the data of the first type excluding the data of the second type, and transmitting the CPSR message excluding the data of the first type except the data of the second type.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method for handling a RPLMN during a disaster situation in a wireless network by a UE. In an embodiment, the method includes selecting RPLMN as PLMN with the disaster condition for accessing the disaster roaming services in response to determining that the RPLMN is included in a list of PLMNs with disaster condition for which disaster roaming services is offered by another PLMN and is allowable. In another embodiment, the method includes skipping the RPLMN and determining a PLMN with disaster condition for acessing the disaster roaming services in response to determining that the at least one PLMN is not included in the list of PLMNs with the disaster condition for which disaster roaming services is offered by the another PLMN or is not allowable.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to an embodiment, the method comprises establishing at least one PDU connection in an S1 mode; performing an inter system change from the S1 mode to an N1 mode; and in case that a successful UE-requested PDU session modification procedure is not previously performed and the UE is in a 5GMM-REGISTERED.NON-ALLOWED-SERVICE state, performing a UE-requested PDU session modification procedure to report 5G session management (5GSM) capability of the UE after entering a 5GMM-REGISTERED.NORMAL-SERVICE state.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The present subject matter refers to a method for a user equipment (UE) including a multi-universal subscriber identity module (MUSIM) in a wireless communication system is provided. The method includes registering to a public land mobile network (PLMN) on both of a 3rd generation partnership project (3GPP) access network and a non-3GPP access network, receiving, from an access and mobility management function (AMF), a message while the 3GPP access network is in an idle state, in case that the message is received over the 3GPP access network, identifying the message is related to a voice service and in case that the message is received over the non-3GPP access network, identifying that the message is related to a non-voice service.
