1. A data synchronization system, comprising:
- a first apparatus,to transmit a synchronization message with meta information, andto perform a first synchronization processing of synchronization data; and
a second apparatus including a data storage unit,to receive the synchronization message with the meta information from the first apparatus,to interpret the meta information included in the synchronization message,to perform a second synchronization processing of the synchronization data in response to the synchronization message,to retain the synchronization data in the data storage unit for a validity period defined based on the meta information, andto remove the synchronization data from the data storage unit when the synchronization data exceeds the validity period,wherein the meta information specifies select synchronization data for synchronization among available synchronization data to minimize frequency of wireless connections for synchronization.

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.
