摘要

PURPOSE: An application money-back guaranteed sales method and a market server for implementing the same are provided to collect applications installed in a user terminal and to facilitate money-back guaranteed sales of a new application. CONSTITUTION: A market server (100) searches for money-back guaranteed sales target applications among applications sold to a user terminal (200) (S210). The market server delivers a quotation message including a list of money-back guaranteed sales target applications and money-back guaranteed sales conditions (S220). The user terminal, if accepting the money-back guaranteed sales conditions, sends an accepting message including the information about returning applications to the market server (S230). The market server requests the deletion of the returning applications to the user terminal (S240). The user terminal deletes the returning applications (S250). The user terminal sends the delete information of the returning application (S251). The market server, after the returning applications are deleted, sends a new application to the user terminal (S260). The user terminal installs the new application (S270). The user terminal reports the completion of installation (S271). The market server settles the payment based on the money-back guaranteed sales conditions (S280). The market server delivers a payment completion message to the user terminal (S281).
