Method of synchronizing data between server and user terminal using messenger service system and system using the same

摘要

Provided are a method of synchronizing data between a server and a user terminal using a messenger service system and a system using the same. In a data synchronization system including a messenger server for storing at least one contact list having information on terminals belonging to one messenger group, and a synchronization markup language (SyncML) server for synchronizing the information on the terminals, upon receiving a request for synchronization of information data to be shared by the group from a first terminal, the SyncML server stores the information data. Upon receiving an information data synchronization request from a second terminal, the Synch ML server requests the messenger server for a contact list of the second terminal. If it is determined that the second terminal belongs to the group to which the first terminal belongs, the SyncML server synchronizes the terminals with respect to the information data.
