Improvements in and relating to multi-access edge computing (MEC)

Disclosed is a method for managing an application instance by a multi-access edge computing orchestrator (MEO) in a multi-access edge computing (MEC) system in a 5G or 6G communication system for supporting a higher data transmission rate, with the method including receiving, from an operational support system (OSS), an application instantiation request including a completion timer in which to finish the instantiation request; selecting at least one MEC platform manager (MEPM) for requesting the application instantiation; transmitting, to the selected MEPM, the application instantiation request; and transmitting, to the OSS, a response indicating that the application instantiation has failed, in case that the completion timer expires before receiving a configuration response from the selected MEPM.
