The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure 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. According to various embodiments, a method for operating a server may comprise the steps of: while at least one service is connected to a terminal, receiving, from another device, a request for providing a first service to the terminal; determining, in response to the request, whether it is possible to provide the first service to the terminal; when the first service cannot be provided, determining whether to terminate one of the at least one service; and, if the one of the at least one service is terminated, transmitting a setup message for the first service to the terminal in response to the termination.
