SYSTEM AND METHOD FOR DYNAMIC ACTIVATION AND DEACTIVATION OF USER PLANE INTEGRITY IN WIRELESS NETWORKS

摘要

User equipment (UE) and a network node may establish data radio bearers (DRBs) for wireless communication of user plane data. For each DRB, the UE and network node may signal static or dynamic integrity protection for the user plane data during set-up of the DRB. When the DRB has static integrity protection, integrity protection is applied to the user plane data for a duration of the DRB. When the DRB has dynamic integrity protection, the UE and network node establish one or more trigger conditions for dynamic integrity protection of the DRB. The integrity protection may be enabled upon detection of one or more trigger conditions and disabled when the one or more trigger conditions subside after a predetermined period of time.
