The present invention relates to a method for negotiating a terminal support function for dynamic content transmission, a terminal for the same, and a server. More specifically, by allowing the DCD server to recognize the support function of the terminal, the DCD server does not transmit unnecessary content that the terminal does not support to prevent the performance degradation of the DCD server and the terminal, and improve network transmission efficiency The present invention relates to a method for negotiating a terminal support function for dynamic content transmission which can be improved, a terminal for the same, and a server.
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 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 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 for delivering the collected content in an optimized form for mobile terminals, and a representative example is Dynamic Content Delivery (DMA), which is being standardized by the Open Mobile Alliance (OMA). Hereinafter referred to as "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 various steps to find the content and visits the content in a difficult manner. 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, since the DCD server does not recognize the function supported by the terminal, the DCD server has a problem of unnecessary content transmission that transmits content that the terminal does not support.
Due to such a problem of unnecessary content transmission, the DCD server has a problem that the user wants to, and does not deliver the appropriate content to the user terminal.
Due to the problem of necessary content transmission mentioned above, there is a problem that causes the performance degradation of the DCD server and the terminal due to unnecessary content transmission.
In addition, due to the problem of unnecessary content transmission, there is also a problem of reducing the data transmission efficiency of the network due to unnecessary content transmission.
In order to solve this problem, an object of the present invention is to enable a DCD server to recognize a support function of a terminal by negotiating a terminal support function between a DCD server and a DCD client in the terminal. The purpose of the present invention is to provide a terminal user with a dynamic content transmission service suitable for the present invention.
Another object of the present invention, through the negotiation of the terminal support function between the DCD server and the DCD client in the terminal, the DCD server can recognize the support function of the terminal, the DCD server does not transmit unnecessary content to the terminal, unnecessary content The purpose is to prevent the performance degradation of the DCD server and the terminal due to the transmission.
Another object of the present invention is to improve transmission efficiency of a network by preventing unnecessary content transmission from a DCD server to a terminal.
According to an aspect of the present invention for achieving this object, before the DCD server transmits the content to the terminal via the network, the DCD server negotiates the terminal support function with the DCD client in the terminal, (a A terminal support function negotiation request step in which the DCD server receives a terminal support function request message including first support function information from the DCD client; And (b) a terminal supporting function negotiation response step of transmitting, by the DCD server, a terminal supporting function response message including second supporting function information to the DCD client.
According to another aspect of the present invention, a DCD server for negotiating a terminal support function of the terminal with the DCD client before the DCD client in the terminal receives the content through the network, (a) from the DCD client A data reception management unit configured to receive a terminal support function request message including support function information, and to receive content from a content providing server storing the content; (b) a terminal support function negotiation manager configured to generate a terminal support function response message including second support function information based on the first support function information of the terminal support function request message received by the data reception manager; ; (c) a data transmission management unit for transmitting the terminal support function response message and the content to the DCD client; And (d) a data storage management unit configured to store data including data related to the content and negotiation of the terminal support function.
According to another aspect of the present invention, in the terminal including a DCD client for negotiating a terminal support function with the DCD server, before the DCD server transmits the content to the terminal over the network, the DCD client, ( a) a terminal support function negotiation manager which performs a function of managing negotiation of the terminal support function with the DCD server; (b) a terminal support function information management unit receiving a negotiation start instruction of the terminal support function from the terminal support function negotiation manager and performing a function of generating first support function information which is the terminal support function information; (c) a message generation management unit that performs a function of generating a terminal support function request message including the first support function information generated by the terminal support function information manager; (d) a message transmission manager for transmitting the terminal support function request message generated by the message generation manager to the DCD server; (e) a message reception management unit that performs a function of receiving a terminal support function response message which is a response message to the terminal support function request message from the DCD server; And (f) a content delivery management unit that performs a function of receiving content from the DCD server and delivering content to an application in the terminal.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function is obvious to those skilled in the art or may obscure the gist of the present invention, the detailed description thereof will be omitted.
