A METHOD OR PROTOCOL FOR SYNCHRONIZING PARALLEL PROCESSORS (12, 14) IN A MOBILE COMMUNICATION SYSTEM IS DISCLOSED, WHEREBY A SYNC ENGINE (104) ASSOCIATED WITH ONE PROCESSOR (12) RETRIEVES THE CURRENT VALUE OF A CHANGE COUNTER FOR A DATABASE (108) ASSOCIATED WITH THE SECOND PROCESSOR (14), STORES THE CURRENT VALUE OF THE CHANGE COUNTER, RETRIEVES ALL DATA ENTRIES FROM THE DATABASE (108) ASSOCIATED WITH THE SECOND PROCESSOR (12), AND PERFORMS A SYNCHRONIZATION PROCEDURE FOR A DATABASE (102) ASSOCIATED WITH THE FIRST PROCESSOR (12) BASED ON ALL OF THE DATA ENTRIES RETRIEVED. BY EXAMINING THE CHANGE COUNTER, THE SYNC (104) ENGINE CAN DETERMINE WHETHER A USER MODIFIED A DATABASE (102, 108) WHILE THE SYNCHRONIZATION WAS IN PROCESS.FIG. 3
