description Provided is a method by which a terminal performs task offloading with at least one satellite in a MEC network. The method comprises the steps of: obtaining at least one initial input value; obtaining, from at least one satellite, information necessary to determine whether to perform task offloading in a time slot (t); setting respective objective functions according to whether to perform task offloading based on information on a terminal and the information necessary to determine whether to perform task offloading that is obtained from at least one satellite in the time slot (t); obtaining the minimum value of each objective function depending on whether to perform task offloading, and comparing the respective minimum values of the objective functions; and determining whether to perform task offloading on the at least one satellite in the time slot (t) according to a result of the comparing. Therefore, the method can perform dynamic optimization in consideration of the distance and propagation delay between the terminal and the satellite, which change in real time, with respect to the satellite continuously moving. MEC 네트워크에서 적어도 하나의 위성과 태스크 오프로딩을 수행하는 단말의 방법이 제공된다. 상기 방법은, 적어도 하나의 초기 입력값을 획득하는 과정; 타임 슬롯 t에서 상기 적어도 하나의 위성으로부터 태스크 오프로딩을 수행여부를 결정하는데 필요한 정보를 획득하는 과정; 상기 타임 슬롯 t에서 상기 단말의 정보 및 상기 적어도 하나의 위성으로부터 획득한 태스크 오프로딩을 수행여부를 결정하는데 필요한 정보를 기반으로 태스크 오프로딩 수행 여부에 따른 목적 함수를 각각 설정하는 과정; 상기 태스크 오프로딩 수행 여부에 따른 각각의 목적 함수의 최소값을 획득하고 상기 각각의 목적 함수의 최소값을 비교하는 과정; 및 상기 비교결과에 따라 상기 타임 슬롯 t에서 상기 적어도 하나의 위성으로 태스크 오프로딩 수행할지 여부를 결정하는 과정을 포함한다.
