Description
The present invention relates to an application registration method, an application release method, and a DCD server and a terminal therefor. More specifically, by registering an application with the DCD server, the DCD server can manage the application included in the terminal matching the channel containing the content to be transmitted, and the inefficiency of transmitting the non-playable content to the application installed in the terminal. Performance of the application registration function and the application release function in the DCD server and the terminal by defining the specification of the message exchanged between the DCD server and the terminal (DCD client) according to the application registration method and the application release method. An application registration method, an application release method, and a DCD server and a terminal therefor are effective for improving the application.
Nowadays, the expansion of the network infrastructure has created a lot of content providers who produce and store the contents they want, and users can receive the contents by directly visiting the sites operated by these contents providers. have.
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, accessing 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 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 using 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 navigates the content through various steps, thereby making the content difficult for the user. The purpose of DCD can be achieved by delivering to the user's terminal without visiting, 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 transmission (DCD) technology is a client-server model, which is performed by interworking with a DCD server serving as a server for transmitting content and a DCD client in a terminal serving as a client receiving content. In addition, the DCD technology defines a message exchanged between the DCD server and the DCD client, and defines a protocol for transmitting and receiving content and messages.
In order for the terminal to receive and play the content in the above-described push or pull mode, an application capable of playing the content must be installed in the terminal and the DCD server, which is the content sender, is aware of the characteristic information of the previously installed application. Since each content can be played by a different application, a channel and an application that accommodate one or more contents must be matched.
However, in the conventional DCD technology, there is no specification for a method for transmitting characteristic information on an application pre-installed in the terminal to the DCD server and a corresponding message. Therefore, since the DCD server does not recognize the information to the application that can play the specific content to be transmitted, there may be a problem that the terminal can not play even if the specific content is transmitted.
An object of the present invention for solving this problem is to register an application to the DCD server, so that the DCD server can manage the application included in the terminal matching the channel containing the content to be transmitted.
Another object of the present invention is to register the application to the DCD server, by managing the application included in the terminal that matches the channel containing the content to be transmitted by the DCD server, thereby reducing the inefficiency of transmitting the non-playable content to the application pre-installed on the terminal To prevent it.
