Abstract: Disclosed is a method for installing applications between mobile terminals capable of easily installing applications installed in an existing mobile terminal in a new mobile terminal at the time of purchasing a mobile terminal. An installation apparatus extracts identification information regarding applications installed in a first mobile terminal from the first mobile terminal connected to communicate data with the installation apparatus for installing data. The installation apparatus extracts link information providing an access path of downloading and installing application files from an application market provided from a web based on the identification information or downloading applications from the application market. The installation apparatus transmits the application files to the second mobile terminal so as to be installed in the second mobile terminal or transmits the link information so as to be stored in the second mobile terminal.
