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.
