Abstract: The present disclosure relates to a communication technique for combining, with an IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and to a system therefor. The present disclosure may be applied to intelligent services (e.g., a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, retail business, security and safety-related service, etc.), based on a 5G communication technology and an IoT-related technology. A method for a user equipment in a first communication system according to the present invention comprises steps in which a user equipment in an inactive state: transmits a paging area update request message; checks whether or not a timer associated with a paging area update has expired; and transitions into an idle state if a response message for the paging area update request message has not been received until the timer has expired.

Abstract: A communication method and system for converging a fifth generation (5G) communication system for supporting higher data rates beyond a fourth generation (4G) system with a technology for Internet of things (IoT) are provided. The communication method and system may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method by a terminal configured with at least one serving cell for performing a random access (RA) procedure is provided. The method includes measuring downlink reference signal received power (DL RSRP) of a serving cell on which the RA procedure is initiated, determining whether the DL RSRP of the serving cell is greater than a threshold, and performing a two-step RA procedure based on the DL RSRP of the serving cell being greater than the threshold.
