Abstract

A data synchronization system is provided. In the data synchronization system, a synchronization message transmitting party transmits a synchronization message with meta information to a synchronization message receiving party, and the synchronization message receiving party interprets and stores the meta information included in the synchronization message, and performs further processing for data that is to be synchronized, according to the meta information. Therefore, the frequency of wireless connections for synchronization is minimized.

Claims

1. A data synchronization system comprising:

a first apparatus transmitting a synchronization message with meta information; and

a second apparatus receiving the synchronization message with the meta information from the first apparatus, interpreting the meta information included in the synchronization message, storing the interpreted meta information, and performing further processing for data that is to be synchronized, according to the meta information.

2. The data synchronization system of claim 1, wherein the meta information defines a validity term of the data that is to be synchronized.

3. The data synchronization system of claim 1, wherein the meta information defines a size of the data that is to be synchronized.

4. The data synchronization system of claim 3, wherein, when the meta information further defines an operation that is to be performed when the size of the data that is to be synchronized reaches a defined size.

5. The data synchronization system of claim 1, wherein the meta information defines a synchronization data storage unit of the first apparatus as a cache for a synchronization data storage unit of the second apparatus.

6. The data synchronization system of claim 1, wherein the meta information defines a synchronization schedule of the data that is to be synchronized.

7. The data synchronization system of claim 1, wherein the meta information defines an operation that is to be performed when an error occurs during synchronization of the data that is to be synchronized.

8. The data synchronization system of claim 1, wherein the meta information defines processing of the data that is to be synchronized.

9. The data synchronization system of claim 8, wherein the processing of the data that is to be synchronized is one of compressing, encrypting, and indexing.
