METHODS AND APPARATUS FOR DATASET SYNCHRONISATION IN WIRELESS ENVIRONMENT Russian patent published in 2011 - IPC H04L29/08 

FIELD: information technology.

SUBSTANCE: methods, apparatus, systems, and computer program products are provided for wirelessly synchronising datasets which are stored on a wireless device and at a network device, such as a network server or database. Present aspects provide a simplified and efficient synchronisation process, whereby synchronisation can be completed in a single round-trip of wireless communication between the wireless device and the network device. Single round-trip synchronisation uses less network resources, shorter overall synchronisation cycle times and lessens the likelihood of wireless network failures, such as call drops or the like, causing the synchronisation process to fail. Also, simplification and efficiency are further realised by creating a synchronisation process which allows the network device dataset to be independent of the wireless device datasets, i.e., the network server does not require a full change history nor is the network server required to know the wireless device dataset version.

EFFECT: high synchronisation accuracy.
