Method, Apparatus and System for Improving Synchronization Efficiency of Really Simple Syndication Service

摘要

The present invention discloses a method, apparatus and system for improving synchronization efficiency of Really Simple Syndication (RSS) service. The method comprises that: an RSS source server receiving and parsing a synchronization request packet sent from a mobile terminal, wherein the synchronization request packet comprises a last synchronization timestamp, then obtaining a last synchronization time; the RSS source server determining whether item contents in a channel are updated from the last synchronization timestamp to a current timestamp; if the item contents in the channel are not updated, the RSS source server sending synchronization data that only comprises a LINK label corresponding to an original item to the mobile terminal; and if the item contents in the channel are updated, the RSS source server adding the updated contents to the synchronization data and sending the synchronization data to the mobile terminal. The present invention can reduce the transmitted data quantity, thus shortening the synchronization time.
