Abstract
The disclosure discloses a method and a system for synchronizing an Access Stratum (AS) security algorithm. The method comprises: a control plane notifying a user plane to start a decryption exception detection when sending an Radio Resource Control (RRC) connection re-establishment message (); the user plane performing the decryption exception detection on a service message received after the RRC connection re-establishment, and sending a decryption exception instruction to the control plane when discovering the decryption exception of the service message (); and the control plane performs a corresponding exception process according to the decryption exception instruction (). With the method, the exception of the AS security algorithm configured for User Equipment (UE) in the RRC connection re-establishment is discovered in time, the bandwidth waste caused by invalid data packets of an air interface is maximally avoided, and the prompt exception recovery is improved, so as to further improve the user experience before and after a handover.
