FIELD: information technology.
SUBSTANCE: this invention relates to network communication technologies. Method comprises: a cloud server receives a data synchronization request sent by a mobile terminal, wherein the synchronization request carries an identifier of the mobile terminal, last time that the data is synchronized by the mobile terminal, and a synchronization account for synchronizing data between the mobile terminal and the cloud server; the cloud server detects that record operation time of data to be synchronized is greater than the last time that the data was synchronized by the mobile terminal, wherein the data to be synchronized is data corresponding to the identifier in the synchronization account on the cloud server; and the data to be synchronized are synchronized between the cloud server and the mobile terminal.
EFFECT: faster data transmission.
