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

A computer program product comprising a non-transitory computer readable storage medium, said computer program product for synchronizing a plurality of extensible markup language (XML) databases on a network with a plurality of extensible markup language (XML) databases on a mobile node, the computer program product comprising:

• computer readable program code embodied at the non-transitory computer readable storage medium and configured to create first hash information pursuant to a first technique, the first hash information being representative of values contained in the mobile node's plurality of databases;
• computer readable program code embodied at the non-transitory computer readable storage medium and configured to communicate the first hash information to the network node;
• computer readable program code embodied at the non-transitory computer readable storage medium and configured to receive at a request detector coupled to receiver circuitry of the mobile node a request from the network for second hash information when the network determines, based at least on the first hash information, that the plurality of databases on the network and the plurality of databases on the mobile node are out-of-match;
• computer readable program code embodied at the non-transitory computer readable storage medium and configured to create the second hash information pursuant to a second technique;
• wherein the first technique is less computationally-intensive than the second technique and the first hash information requires less communication channel capacity than the second hash information;
• and
• computer readable program code embodied at the non-transitory computer readable storage medium and configured to receive a fetch request, piggybacked with second data for the mobile node based upon a type of synchronization, when the second hash information is indicative of a change to data of which the second hash information is representative.
