That is, the Enabled state ID that can be set to the terminal state ID means a unique ID value for the state of the terminal, through which the DCD client can receive the contents by registering the application with the DCD server.
Referring to FIG. 2, the terminal status information report response step (S 204) is a step in which the DCD server transmits a terminal status information report response message, which is a response message to the terminal status information report message received from the DCD client in the previous step (S 202) To the client.
The terminal status information high response message transmitted from the DCD server to the DCD client in the terminal status information reporting response step (S 204) includes primitive type ID information for identifying the message type, a transaction for identifying the message processing, ID information, session ID information for identifying a session in which the corresponding message processing is performed, and transaction result information corresponding to a transaction ID.
After the UE status information report response step (S 204), the DCD server determines whether to transmit the content according to the UE status information reported from the DCD client in the terminal. If the terminal status is Disabled or Suspended, the content is not transmitted to the DCD client. If the terminal status is Enabled, the content is normally transmitted to the DCD client.
In summary, the DCD server receives information on the status of the DCD client and the terminal from the DCD client through the terminal status information reporting method for transmitting the dynamic content, and determines whether to transmit the content to the DCD client .
Using the terminal status information reporting method for dynamic content transmission, when the terminal is in a state where it can not receive the content, the DCD server receives the terminal status information from the DCD client of the terminal and does not transmit unnecessary content to the terminal The efficiency of network use and the interworking efficiency between the DCD server and the terminal can be improved.
