A method for controlling a function and a DCD server therefor.

Nowadays, due to the expansion of network infrastructure, there are many content providers that produce and store the contents that users want, and users can receive the contents by visiting the relevant sites operated by these contents providers. .

In order to effectively deliver such contents, Web Syndication is urgently needed to deliver information produced and changed in real time on the Internet, and RSS (Really Simple Syndication) is a kind of Web Syndication. ), And ATOM have been proposed and become a standard, and such a content can be distributed by RSS (Really Simple Syndication), ATOM, etc., and collection of content through a program such as RSS Reader has also become much smoother.

However, in a relatively resource-constrained mobile environment, access to content distributed using RSS / ATOM as in a PC environment is limited. In order to solve this problem, there is a demand for a method for delivering the collected content in an optimized form for mobile terminals, and a representative example is Dynamic Content Delivery (DCD), which is being promoted by the Open Mobile Alliance (OMA). "DCD"). DCD seeks to deliver the user's desired contents to the terminal user in the most effective way by reflecting the user's preference. As a content delivery technique, the DCD server sends a content update (transmission) notification message to the terminal. A push method using a DCD-2 interface for receiving a content update (transmission) request message from a terminal and transmitting the corresponding content to the terminal has been proposed.
