Abstract
The present disclosure relates to a communication technique for converging IoT technology with 5G communication systems for supporting higher data transmission rates than 4G systems and to a system thereof. The present disclosure can be applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security- and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technologies. The method for operating a policy and charging function (PCF) according to one embodiment of the present invention comprises the steps of: receiving a message which is generated by an application function (AF) and requests a change in the traffic route of terminal; checking priority information of the terminal, regarding services provided by the AF, included in the message; and changing the protocol data unit (PDU) session connection of the terminal on the basis of the priority information.
