Abstract
Exemplary embodiments include a UE that determines that access stratum (AS) security has not been activated and mobility is handled by a 5G core network. The UE then encodes a radio resource control (RRC) connection re-establishment request for transmission based on the determination. The RRC connection re-establishment request may include an indicator of a UE identity or a single bit value to indicate a reestablishment cause. The UE may also determine a truncated ng-5G-S-TSMI of the UE, wherein the RRC connection re-establishment request includes the truncated ng-5G-S-TSMI.
