Abstract

A method and dynamic content delivery (DCD) system for content update from a server to a client terminal comprising receiving a first message containing an identification information of one or more contents available for update from the server by a client terminal, sending a second message containing the identification information of a specific content to be updated among the one or more contents to request content update to the server; and receiving a third message containing the content or the address thereof corresponding to the identification information contained in the second message to respond to the second message.

Claims

1. A method for content update from a server to a client terminal in a dynamic content delivery (DCD) system, the method comprising:

sending a first message including a content list to the client terminal, the content list including identification information and size information on one or more contents subject to update to thereby help a user to manage a memory in the client terminal;

the server receiving a second message from the client terminal requesting updated content with the second message including the identification information on at least one contents selected by the client terminal from the content list and further including a delivery priority set by the client terminal associated with the at least one contents subject to update included in the first message wherein the priority in delivery is set differently for each content by the client terminal for delivering said at least one contents to the client terminal; and

sending a third message from the server to the client terminal in response to the second message including said at least one contents or the address thereof requested by the second message subject to delivery pursuant to the delivery priority set by the client terminal included in the second message.

2. The method as claimed in claim 1, wherein the size information includes both the size of each content in the content list and the total size of all the contents in the content list.

3. The method as claimed in claim 1, wherein the delivery priority for delivering said at least one contents to the client terminal is set by the client terminal.

4. The method as claimed in claim 1, wherein the identification information includes at least one of channel-ID and content-ID.

5. The method in claim 1, further comprising:

receiving a fourth message notifying the result of content receipt from the client terminal.

6. A method for content update from a server by a client terminal in a dynamic content delivery (DOD) system, the method comprising:

sending a first message from the server to the terminal which includes a content list comprising identification information and size information on one or more contents subject to update to thereby help a user to manage a memory in the client terminal;

sending a second message to the server from the terminal in response to the first message requesting updated content with the second message including the identification information on said at least one contents selected by the client terminal from the content list and a delivery priority set by the client terminal associated with said at least one contents; and

with the terminal receiving a third message from the server in response to the second message pursuant to the delivery priority of the client terminal included in the second message with the delivery priority being set differently for each content by the client terminal such that the third message includes said at least one contents or the address thereof requested by the second message pursuant to said delivery priority as set differently for each content by the client terminal when delivering said at least one contents to the client terminal included in the second message.

7. The method as claimed in claim 6, wherein the size information includes both the size of each content in the content list and the total size of all the contents in the content list.

8. The method as claimed in claim 6, wherein the delivery priority for delivering said at least one contents to the client terminal is set by the client terminal.

9. The method as claimed in claim 6, wherein the identification information includes at least one of channel-ID and content-ID.

10. The method in claim 6, further comprising:

sending a fourth message notifying the result of content receipt to the server.
