    Abstract: An apparatus comprises a memory unit, and a control unit connected to the memory unit. The apparatus can be configured to interface at least one access node; the control unit is configured to derive at least one local level security key within an established security context for a terminal, forward the derived local security key to at least one access node, and detect failures in a handover for a terminal being served by a first access node towards a second access node. The failures concern the interface between the apparatus and the second access node. In response to a verified trigger condition, the control unit can re-adjust local level security keys with keys maintained at the terminal within the established security context.
