Method and system for reproducing multimedia content stored in mobile communication terminal in gray area

A system and a method for reproducing multimedia content, whose reproducing is limited by DRM(Digital Rights Management), stored at a mobile communication terminal in an area where auth time can not be obtained is provided to enable a mobile communication service provider to create a new added value through promotion of CPs(Content Providers) by utilizing multimedia content during an authentication period of the multimedia content though the mobile communication terminal is located in an area where a communication service is provided. A method for reproducing multimedia content, whose reproducing is limited by DRM(Digital Rights Management), stored at a mobile communication terminal in an area where auth time can not be obtained comprises the following several steps. A right issuing server transmits encrypted multimedia content and a right object to a mobile communication terminal at the request of the mobile communication terminal(S300). The mobile communication terminal searches for a DRM agent in the right object, stores the DRM agent, drives the DRM agent, and makes the DRM agent check whether the mobile communication terminal is located within a service area(S302). If the mobile communication terminal is located within the service area, the DRM agent requests a microprocessor to cyclically update auth time(S304). If the terminal is not located within the service area, the terminal drives a count program supported by the DRM agent, generates current time information, and updates the auth time by adding the current time information to final auth time on the basis of the auth time finally updated while the terminal is being located within the service area(S306).
