Abstract: Systems and methods of a security framework for an RRC connection are described. The UE receives a release message that comprises a current Next Hop Chaining Counter (NCC). The UE derives a new KeNB* using the current NCC and transmits an EDT RA preamble to same or a different base station. After receiving an RAR with an uplink allocation, the UE transmits a RRCConnectionResumeRequest message. The UE transmits uplink data encrypted using KeNB* if the uplink allocation includes a data allocation sufficient for the data, fall backs to a legacy RRC connection procedure in which the stored KeNB* is discarded and then KeNB* is re-derived if the data allocation is insufficient for the data due to a CE level change, and fall backs to a legacy RRC connection procedure in which the stored KeNB* is used instead of discarding KeNB* if the uplink allocation excludes the data allocation.

Abstract: A cardboard blank has a plurality of fold lines dividing the blank into section for folding into a loose leaf folder or a box file. The fold lines define two cover sections between which there is a spine portion having multiple spine fold lines defining a binding zone which can be formed as a double thickness ridge to which papers can be attached. The fold lines additionally define various flaps which can be folded flat onto the cover portions to form a loose leaf file or which can extend to form a box shape with the cover portions and spine portion.
