Abstract: This disclosure describes methods, systems, and devices for uplink data integrity protection in a communication system including a radio access network (RAN) serving a user equipment (UE) operating in an Early Data Transmission (EDT) configuration. In one example, a method involves generating a hash marker based on a packet data convergence protocol (PDCP) control protocol data unit (PDU) or service data unit (SDU). The method also involves transmitting a message including the hash marker to the RAN.

Abstract: A method for a re-authentication of user equipment (UE), by at least a portion of a core network (CN), for steering of roaming (SoR) data delivery, includes receiving, through next generation radio access network (NG-RAN) and/or 5G system (5GS), a subscriber data management (SDM) data request for a UE. The method includes determining that re-authentication of the UE be requested. The method includes encoding a response for transmission to the UE responsive to the SDM data request. Determining that re-authentication be requested can include determining that SoR data is being sent to the UE.

Abstract: Systems, devices, and techniques for handover and false base station detection in a wireless communication network are described. A described technique performed by a user equipment (UE) includes receiving, from a source base station of a wireless network, a handover command to indicate a handover to a target base station for communication in the wireless network; receiving information from the target base station; determining whether the target base station is a legitimate base station of the wireless network based on the information from the target base station and handover information included in the handover command; and performing a handover based on the handover command and a determination that the target base station is the legitimate base station.

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.
