Abstract: The disclosure relates to a communication scheme for converging a 5th generation (5G) system for supporting a higher data rate after a 4th generation (4G) system with Internet of things (IoT) technology, and a system thereof. A wireless communication system, and more particularly, an application layer network structure for providing an edge computing device in a cellular wireless communication system (a 5G system), and a method thereof are provided. An edge enabler server (EES) receives a first message including information about one or more edge application servers (EASs) from an EAS management system, and transmits a second message for requesting instantiation for at least one EAS among the one or more EASs to the EAS management system, based on the information about the one or more EASs included in the first message. The information about the one or more EASs includes at least one of information about an identifier (ID) of each of the one or more EASs, information indicating whether each of the one or more EASs supports instantiation, or instantiation type information for each of the one or more EASs.
