METHODS AND DEVICES FACILITATING SYNCHRONISATION OF SECURITY CONFIGURATIONS Russian patent published in 2014 - IPC H04W36/00 

FIELD: radio engineering, communication.

SUBSTANCE: terminal sends a security mode complete message to the network entity, on the receipt of which the network entity updates new security parameters. The access terminal initiates a mobility procedure while the security mode procedure is on-going, aborts the security mode procedure and reverts back to the old security parameters. The access terminal sends a mobility update message to the network entity including a dedicated status indicator configured to inform the network entity that the access terminal has reverted back to the old security parameters. In response to the mobility update message, the network entity reverts back to the old security parameters.

EFFECT: facilitating synchronisation of security parameters between access terminals and a wireless network.
