A method for synchronizing a first database including first data records with a second database including second data records. The method includes starting a synchronization session with an electronic device on which the second database resides, requesting the first data records from the first database, temporarily disconnecting the synchronization session while awaiting receipt of the first data records, receiving the first data records, and restarting and completing the synchronization session.

Method and apparatus for synchronizing of databases

A synchronization process, and associated apparatus, for placing database copies in match with one another by way of communications effectuated upon an air interface of a radio communication system. Hash functions are performed at a mobile node and at a network part upon mobile and network copies of database information. Comparison of the hash information formed therefrom provides a preliminary indication of whether the databases are in match with one another. If a determination is made that the databases are out of match, the data is compared, and the data is placed in match with one another responsive to such additional comparisons.

Apparatus, and associated method, for synchronizing databases connected by way of a radio air interface

Apparatus, and an associated method, for facilitating synchronization of databases connected by way of a radio air interface. Changes to a data record embodied at the network part are detected by a detector. A mapping is performed by a mapper, and a synchronization request is generated by a synchronization request generator. The synchronization request is filtered by a filter, and converted into form to permit its efficient communication upon the radio air interface to a mobile node pursuant to a synchronization session.

Apparatus, and associated method, for facilitating synchronization of databases connected by way of a radio air interface

Methods and apparatus for the synchronization of first data stored to a wireless mobile device and second data stored to a remote device are provided. Schema describing the data is maintained by the device. The schema is provided by the device to assist with the synchronization. Changes to device data schema may be transparently handled by a synchronization server. In one embodiment, a method for synchronizing first data stored to a mobile device and second data stored to a remote storage device comprises receiving a schema from the mobile device describing the first data; matching respective instances of the first and second data using the schema; determining differences between the first and second data in response to the matching; and updating at least a one of the first and second data in response to the differences.
