Abstract:
Disclosed are a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system thereof. The present disclosure can be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety-related services, and the like), based on a 5G communication technology and an IoT-related technology. One embodiment of the present invention relates to a method by which a terminal updates system information, and a terminal for performing the method, which comprises the steps of: acquiring first system information and second system information from a first cell; starting a timer corresponding to the second system information; determining whether the second cell is a cell that shares the second system information with the first cell, if the terminal has moved from the first cell to the second cell; and updating the second system information on the basis of the determination result.
