Description

Method of providing content transmission service according to billing information agreement, DCC server and terminal for it {Mehtod, DCD Server and Terminal for Delivering Content Based on Conference with Terminal about Charge Information for Content}

The present invention relates to a method for providing a content transmission service according to a billing information agreement, a DCD server and a terminal therefor. More specifically, by providing a function of notifying the user of the billing information when a billing information change, content update request, etc. occurs, it is possible to recognize the billing information for the content to be provided to the user in advance, the billing information, Accordingly, the present invention relates to a method of providing a content delivery service according to a billing information agreement, which has an effect of preventing unreasonable fee expenditure, improving content delivery service satisfaction, and increasing economic profits to a content delivery service provider, and a DCD server and a terminal therefor. .

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 urgently needed as a way to deliver information that is produced and changed in real time on the Internet, and as such a web syndication, RSS (Really Simple Syndication) and ATOM, etc. This proposal has become a standard, and the distribution of contents is possible due to such RSS and ATOM, and the collection of contents 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 the user's terminal and providing the desired content by maximizing the user's preference. 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 update (transmission) request from an existing user's terminal.

This dynamic content delivery (DCD) technology is a client server model, which is performed by interworking with a DCD server serving as a server for delivering content and a DCD client in a terminal serving as a client for receiving content. It defines the standard for the messages exchanged between the DCD server and the DCD client, and the protocol for the content and the way of sending and receiving the messages.
