Disclosed are: a communication method for incorporating an IoT technique with a 5G communication system for supporting a higher data transmission rate than that of a 4G system or a subsequent system; and a system therefor. The present invention can be applied to intelligent services (for example, services related to smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security, safety, and the like) on the basis of a 5G communication technique and IoT-related techniques. A method for transmitting and receiving a signal by a base station in a mobile communication system comprises the steps of: receiving a handover request message including a first information related to a device-to-device (D2D) service for a handover target terminal; and allocating D2D resources to the terminal based on the handover request message.
