Abstract: Embodiments disclosed herein relate to allowing unauthenticated UEs to gain restricted access to an operator network to access network access subscription service. Once the unauthenticated UE successfully downloads a subscription profile for accessing the operator network, the unauthenticated UE can disconnect and can, thereafter, authenticate to the operator network using the subscription profile. Embodiments disclosed herein can perform one-way authentication to the operator network for obtaining a limited connectivity to reduce DoS attacks on the operator network. More specifically, these embodiments can support unauthenticated UEs to allow unauthenticated UEs to access the operator network for RLOS while minimizing DoS attack.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for performing a restricted local operator services (RLOS) authorization procedure. Various embodiments enable a network to authorize a user equipment (UE) with an RLOS access or subscription properly while aiding in minimizing or preventing potential denial-of-service (DoS) attacks. Other embodiments may be described and claimed.

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.
