Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed is a method of operating a user equipment (UE) operable to communicate with a telecommunication network, comprising the steps of: the UE sending to the telecommunication network a control plane service request (CPSR) message with cellular Internet of Things (CIoT) user data, associated with a protocol data unit (PDU) session; the UE receiving from the telecommunication network a SERVICE ACCEPT message, indicating that the PDU session is inactive in the network; and the UE verifying if the PDU session has an identity the same as an identity of the PDU session included in the CPSR message with CIoT user data and, if so then the UE determines that the CIoT user data was not successfully sent to the telecommunication network or to a final recipient.
