METHODS AND APPARATUSES FACILITATING SYNCHRONIZATION OF SECURITY CONFIGURATIONS

摘要

PROBLEM TO BE SOLVED: To provide methods and apparatuses for synchronizing security parameters between access terminals and a wireless network.SOLUTION: An access terminal sends a security mode complete message to a network entity. On receipt of the security mode complete message, the network entity performs update to new security parameters. The access terminal initiates a mobility procedure while a security mode procedure is ongoing. The access terminal aborts the security mode procedure and reverts back to old security parameters, and sends to the network entity a mobility update message including a dedicated status indicator adapted 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.
