The present invention relates to a content delivery method according to the terminal state management, a content delivery server and a terminal therefor. More specifically, when the DCD server generates the content to be transmitted (updated) to the terminal, the content is directly transmitted to the terminal using the pre-stored and managed terminal address information without using the SMS push function. By transmitting, it is possible to reduce the overhead incurred in the DCD server and the transmission network according to the SMS push-based transmission method and to reduce the transmission delay incurred in transmitting the corresponding content, thereby providing a quick content delivery service to the user. The present invention relates to a content transmission method according to the terminal state management, a content transmission server and a terminal therefor.

Nowadays, the expansion of 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 has been urgently needed as a way to deliver information produced and changed in real time on the Internet. 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 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").

The DCD seeks to deliver the contents desired by the user to the terminal user in the mobile environment in the most effective way by reflecting the user's preference. As a content delivery technique, the DCD-1 interface and There is a pull method and a push method using the DCD-2 interface.

In the existing mobile service, DCD technology breaks away from the way a user's terminal accesses a site on the wireless Internet and goes through various steps to find the content, and delivers the content to the user's terminal without having to visit the user. In addition, by maximizing the reflection of the user's preference (Preference) can provide the content desired by the user.

DCD technology is implemented as a client server model, which is performed by interworking with a DCD server acting as a server for transmitting content and a DCD client in a terminal serving as a client for receiving content. It defines the messages sent and received between clients, and it defines the protocol for the contents and the way of sending and receiving messages.

In the conventional DCD technology, when a DCD server (content delivery server) generates content to be transmitted (updated) to a terminal, the corresponding content is transmitted to the terminal by using an SMS Push (Short Message Service Push) function. The SMS push-based transmission method according to the execution of the notification function according to the SMS push function has a problem of generating overhead in the DCD server and the transmission network. In addition, the SMS push-based transmission method according to the execution of the notification function according to the SMS push function, after transmitting the update notification message using the SMS push function after receiving the transmission request to transmit the corresponding content only after the corresponding terminal is connected By doing so, there is a problem in that it does not provide a quick content delivery service to the user.
