Abstract
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.
