Disclosed are a communication technique of merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety related services, and the like) on the basis of 5G communication technology and IoT related technology. According to one embodiment of the present invention, a communication method of a base station comprises the steps of: determining an RRC state transition condition of a terminal; and transmitting information on the RRC state transition condition to the terminal, wherein the RRC state transition condition can include at least one timer for the transition between RRC states and/or information indicating an RRC state to be changed.
