Abstract

Techniques are disclosed for synchronizing service data between a data store and a device using the service data. These synchronization techniques may be used with a synchronization method and device that adaptively adjust synchronization parameters, such as the synchronization interval and quantity of synchronized data, on a per-end-user basis in response to actual end-user behavior. In particular, heavy users of service data are rewarded with improved synchronization parameters, such as a combination of shorter synchronization intervals and increased synchronization data quantities, which provides closer to “direct access” performance. Light users of service, on the other hand, are assigned lower cost synchronization parameters, such as longer synchronization intervals and/or decreased synchronization data quantities.
