Abstract: Techniques discussed herein can facilitate improved security establishment procedures for Vehicle to Everything (V2X) direct connections. Various embodiments are employable at or comprise User Equipment, and can initiate and/or receive V2X security establishment connections wherein a receiving UE can reject the connection based on the initiating UE's capabilities/policy and/or the initiating UE can make the final decision regarding the connection based at least on receiving security policy and capability information from the receiving UE.

Abstract: A network may authenticate a user equipment (UE) to access an edge data network. The network generates a first credential based on a second credential, the second credential generated for a procedure between the UE and a cellular network corresponding to the network component, receives an identifier associated with the first credential from a further network component in response to the UE transmitting an application registration request to a server associated with an edge data network and retrieves the first credential based on the identifier. The network also receives a multi-access edge computing (MEC) authorization parameter, verifies the MEC authorization parameter and transmits an authentication verification response to a second network component.

Abstract: Techniques for identity-based message integrity protection and verification between a user equipment (UE) and a wireless network entity, include use of signatures derived from identity-based keys. To protect against attacks from rogue network entities before activation of a security context with a network entity, the UE verifies integrity of messages by checking a signature using an identity-based public key PKID derived by the UE based on (i) an identity value (ID) of the network entity and (ii) a separate public key PKPKG of a private key generator (PKG) server. The network entity generates signatures for messages using an identity-based private key SKID obtained from the PKG server, which generates the identity-based private key SKID using (i) the ID value of the network entity and (ii) a private key SKPKG that is known only by the PKG server and corresponds to the public key PKPKG.

Abstract: This disclosure relates to techniques, base stations, and user equipment devices (UEs) for performing base station authentication through access stratum signaling transmissions. The UE may operate in idle mode and may receive an authentication message from a base station through the wireless interface while operating in idle mode. The UE may determine whether a signature comprised within the authentication message is valid, and the UE may continue a connection procedure with the base station based on a determination that the signature is valid. If it is determined that the signature is invalid, the UE may designate the base station as a barred base station and may perform cell re-selection. The authentication message may be one of a radio resource control (RRC) connection setup message, a special RRC message, a media access control (MAC) message, or a random access channel (RACH) message comprising a random access response (RAR) message.

Abstract: A user equipment (UE) includes first and second subscriber identity modules (SIMs), possibly subscribed to different carriers. When the first SIM is in a connected state and the second SIM is in an idle state, the UE may need to periodically tune away a radio from a first frequency used for communication under the first SIM to a second frequency used for idle mode activity under the second SIM. The UE may provide to the network of the first SIM the second SIMs traffic activity pattern and/or serving frequency so that the network may provide coordinated configuration and/or scheduling for the UE device, e.g., in order to make the action of tuning away (and tuning back) the radio more efficient and/or to decrease the network impact of such radio tune aways (e.g., to decrease wasted uplink scheduling and wasted downlink transmissions for the first SIM).

Abstract: Apparatuses, systems, and methods to perform attachment of a wireless device to a next generation gateway via either a base station of a next generation radio access network (RAN) or a mobility management entity of a legacy RAN. An apparatus may be configured to receive an attachment request from a wireless device, determine authentication information via communication with a home subscriber server, determine, based at least in part on the authentication information, whether the wireless device is capable of communicating via the next generation RAT, and send, in response to determining the wireless device is capable, a connection request to a gateway of the next generation RAN. The authentication information may include subscription information associated with the wireless device.

Abstract: This disclosure relates to techniques for performing network initiated downlink data transmissions with a wireless device in a cellular network. According to some embodiments, a wireless device and a cellular network may perform an attach procedure. As part of the attach procedure, the wireless device may indicate to the cellular network to store context information associated with the wireless device after the attach procedure is completed and the wireless device transitions to idle mode. The wireless device may also store context information. The stored context information may be used in conjunction with a network initiated downlink data transaction between the cellular network and the wireless device.
