DCD server for providing dynamic content delivery service to a terminal {DCD Server for Providing Terminal with Dynamic Content Delivery}

The present invention relates to a DCD server for providing a dynamic content transmission service to a terminal. More specifically, the DCD server for providing a dynamic content delivery (DCD) service to the terminal manages user information, content related information, and fee related information of a user of the DCD service using newly defined server content metadata. And a DCD server that provides a dynamic content delivery service to a terminal having an effect of providing a satisfactory dynamic content delivery service to a user by performing transmission scheduling for corresponding content.

Recently, due to the expansion of the network infrastructure, a large number of content providers have been producing and storing contents desired by the users, and the users can receive the content by directly visiting the corresponding site operated by the contents provider .

In order to effectively deliver such contents, Web Syndication is desperately needed as a way to deliver information that is produced and changed in real time on the Internet, and RSS (Really Simple) is a kind of Web Syndication. Syndication), ATOM, and the like have been proposed and become standard. Such RSS (Really Simple Syndication), ATOM, and the like make it possible to distribute content, and the collection of content through a program such as RSS Reader is also much smoother.

However, in a mobile environment with a relatively limited resource, accessing contents distributed using RSS / ATOM as in a PC environment is limited. In order to solve this problem, there is a demand for a method of delivering collected contents optimized for a mobile terminal in an optimized form. Representative examples include a Dynamic Content Delivery (DCD) scheme in which an Open Mobile Alliance (OMA) Quot; 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. By the push method using the DCD-2 interface, the user's terminal accesses the site on the wireless Internet in the existing mobile service and goes through the various steps to find the content, thereby making it difficult for the user to visit the content. The purpose of DCD can be achieved by delivering to a user's terminal and providing contents desired by the user by maximizing reflection of the user's preference. In addition, the DCD also accepts a pull method using a DCD-1 interface in which a DCD server transmits content to a terminal by a content updater (transmission) request from an existing user's terminal.

This dynamic content transmission (DCD) technology is a client server model, which is performed by interworking a DCD server acting as a server for transmitting contents and a DCD client serving as a client receiving contents, Defines the messages exchanged between the DCD server and the DCD client, and specifies protocols for the content and message exchange.

However, in the conventional DCD technology, there is a problem in that user information, content related information, and fee related information for the DCD service user are not managed.

In addition, in the conventional DCD technology, the user information, content related information, and fee related information for the DCD service user are not managed, and thus there is a problem in that a satisfactory dynamic content transmission service cannot be provided to the user.
