Abstract
There is a problem in conventional technologies in that updating multimedia content can be initiated only by a mobile communication terminal side. A mobile communication terminal according to the present invention updates at least one of elements of content stored in a permanent storage area of a memory unit using update information included in an update message received through a wireless communication unit, and plays the updated content. The content can be updated from text information included in the update information, files stored in the mobile communication terminal, or network resources. Accordingly, content providers can update the content stored in the mobile communication terminal by transferring the update information of the content to be updated, for example, using an update message which is a push-type communication means such as a text message.
