This invention is a method and a system to improve the detection of an out of ciphering parameter synchronization of a communication linkage in a ciphering-deciphering wireless communication system. The sender fills the unused data fields of a data package before sending, and the receiver verifies the content of data fields and the particular pattern of the unused data field of a received data package for discrepancy. If the accumulated error count of the receiver exceeds a predetermined threshold, the receiver will invoke a resynchronization of this communication link between the sender and the receiver.
