Abstract: The present disclosure relates to a communication method and 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 present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology. A method of handling control plane data in a wireless network. The method comprises sending, by a user entity (UE), a non-access stratum (NAS) message along with an indication data to a mobility management (MM) core network entity. The MM core network entity processes the received NAS message and the indication data. The MM core network entity determines status of network congestion upon processing the processed NAS message. Sending, by the MM core network entity, a response to the UE based on at least one of the processed indication data and the determined network congestion.

Abstract: The present disclosure relates to a communication technique for converging an IoT technology with a 5G communication system for supporting a higher data transfer rate beyond a 4G system, and a system therefor. The present disclosure can be applied to an intelligent service (e.g. a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, a retail business, a security and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. The present disclosure provides a method wherein, after a MICO mode terminal establishes a connection and transmits data, the MICO mode terminal can be kept in a connected mode state, rather than entering an idle mode, in order to provide for a case where slightly delayed response traffic occurs according to the type of application or service.
