Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an unmanned aerial vehicle (UAV) user equipment (UE) may perform a registration procedure with a UAV service supplier (USS) device via a network connection to register with the USS device. The UAV UE may perform a registration procedure with a core network device to register with a network associated with the core network device based at least in part on performing the registration procedure with the USS device. The UAV UE may receive, from the core network device, an indication to perform an authentication and authorization procedure only after performing the registration procedure with the USS device and after performing the registration procedure with the core network device. Numerous other aspects are provided.

Abstract: The present disclosure provides techniques that may be applied, for example, in a multi-slice network for maintaining privacy when attempting to access the network. An exemplary method generally includes transmitting a registration request message to a serving network to register with the serving network; receiving a first confirmation message indicating a secure connection with the serving network has been established; transmitting, after receiving the first confirmation message, a secure message to the serving network comprising an indication of at least one configured network slice that the UE wants to communicate over, wherein the at least one configured network slice is associated with a privacy flag that is set; and receiving a second confirmation message from the serving network indicating that the UE is permitted to communicate over the at least one configured network slice.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) (e.g., an unmanned aerial vehicle (UAV)) may receive an approved flight plan including approved flight plan sectors. The UE may also receive a query from a network node, the query including an indication of a subset of the plurality of approved flight plan sectors and a request for a plurality of waypoints of the UE within the indicated subset of the plurality of approved flight plan sectors. The UE may further determine, in response to receiving the query from the network node, a flight path including the plurality of waypoints of the UE for the indicated subset of the plurality of approved flight plan sectors based on the received approved flight plan, and the UE may transmit, to the network node, a flight declaration message including the waypoints of the UE.

Abstract: Aspects of the present disclosure provide for a security model for enabling multiple connectivity and service contexts while sharing a single connectivity context to establish a network connection. A context (e.g., connectivity context, service context, security context) is a set of information describing the connectivity, service, or security established between two or more entities. The connectivity context and service context may be established at different network nodes or entities. In one aspect of the disclosure, a connectivity context includes an Evolved Packet System (EPS) Mobility Management (EMM) context or both an EMM context and an EPS Session Management (ESM) context.

Abstract: The disclosure relates in some aspects to establishing connectivity with a network using a first set of credentials and determining whether additional connectivity needs to be established (e.g., using a second set of credentials) to communicate data. The disclosure relates in some aspects to the use of multiple credentials for access and service connectivity. For example, traffic generated by a device may be authorized based on a different set of credentials than the set of credentials used to access the network (e.g., to connect to an LTE network for a PDN connection). In this way, traffic belonging to a specific service or application can be charged and policed based on service specific needs. The disclosure thus relates in some aspects to the use of access credentials and service credentials. These different types of credentials can be used to enable traffic differentiation and policing based on the credentials in use.

Abstract: Methods, systems, and devices are described for wireless communications. A wireless communication system may use access preferences to indicate a preferred access for communicating signaling for a control plane service. In some aspects, an AMF and a UE may establish access preferences for one or more control plane services and communicate signaling for the control plane service based on the established access preferences. In some cases, the UE may transmit modified access preferences for a control plane service to the AMF, and the UE and AMF may communicate signaling for the control plane service based on the modified access preferences. In some aspects, an AMF may also restrict the accesses used by a control plane service. A UE may also request that certain accesses are restricted for use by a control plane service.

Abstract: Unmanned aerial vehicles (UAVs) usually have associated categories based on characteristics of the UAVs and characteristics of flights for the UAVs. These categories are provided to a UAV service supplier (USS) when the UAV registers with the USS and when the UAV submits flight plans to the USS for approval. Such categories are not provided to a wireless communication network that the UAV will use during flight. However, the wireless communication network cannot effectively prioritize service to some UAVs over other UAVs without these categories. Techniques and apparatuses described herein provide categories associated with UAVs to a mobile network that will provide service to the UAVs during flight. The categories may allow the mobile network to prioritize traffic to render operable UAVs that require low-latency communications, such as UAVs using autonomous navigation software, as well as reduce risk to UAVs engaged in high-risk or high-priority missions.

Abstract: A system and method for enabling voice services using a network component in a communication system including a user equipment (UE) is provided. The UE is configured to receive a first message which may be a SIP request. The network component is configured to create a second message, or SIP request, based upon the first message. The network component further configured to subsequently receive a SIP response and select a subsequent action upon receiving the SIP response.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network, a procedure rejection message for non-cellular access at a non-access stratum (NAS) layer, and provide a first congestion indication from the NAS layer to lower layers for non-cellular access based at least in part on the receiving the procedure rejection message. The UE may refrain, at the lower layers, from initiating establishment of a signaling connection based at least in part on the first congestion indication. Numerous other aspects are provided.

Abstract: In an aspect, a network may support a number of client devices. In such a network, a client device transmits a request to communicate with a network, establishes a security context, and receives one or more encrypted client device contexts from the network. An encrypted client device context enables reconstruction of a context at the network for communication with the client device, where the context includes network state information associated with the client device. The client device transmits a message (e.g., including an uplink data packet) to the network that includes at least one encrypted client device context. Since the network device can reconstruct the context for the client device based on an encrypted client device context, the network device can reduce an amount of the context maintained at the network device in order to support a greater number of client devices.

Abstract: Aspects of the disclosure relate to a method of operating a user equipment for wireless communication with a network. In some aspects, the UE establishes a connection to a network and obtains a control plane message from the network. The control plane message may include one or more types of policy information if a size of the one or more types of policy information is less than or equal to a maximum payload size of the control plane message, or information indicating at least a network location from where the one or more types of policy information may be obtained by the UE over a user plane if the size of the one or more types of policy information is greater than the maximum payload size of the control plane message, or a combination thereof. Other aspects, embodiments, and features are also claimed and described.

Abstract: Exchange of flight path information between a mobile network and an unmanned aerial vehicle (UAV) assumes a particular format for the flight path information, usually a waypoint format. However, there are many circumstances in which the mobile network may prefer flight path information in other formats, such as polygon formats (also referred to as “flight volume formats”). Techniques and apparatuses described herein provide greater flexibility with respect to formatting requests for flight path information and encoding responses to such requests. For example, a base station may transmit a request for flight path information with a format indicator that informs a UAV of a desired format for the requested flight path information. The UAV may then provide the flight path information according to the format indicator.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive a broadcast remote identification (BRID) message from a unmanned aerial vehicle (UAV), where the BRID message may include an identity of the UAV. The wireless device may identify UAV information associated with the UAV based on the UAV ID. In some cases, the wireless device may be configured with information that enables the identification of the UAV information. In other cases, the wireless device may request the UAV information from a network entity, such as a UAV flight management system (UFMS), which provides the requested UAV information. In some examples, the UFMS may request the UAV information from an unmanned aerial system (UAS) service supplier (USS) based on the BRID information. Upon identifying the UAV information, the wireless device may broadcast the UAV information to manned aerial vehicles, thereby indicating a presence of the UAV.

Abstract: Various embodiments enable broadcast communications security. Various embodiments enable the authentication of broadcast communications. Various embodiments may enable asymmetric authentication and integrity protection of small size messages, such as one or more signed messages totaling a length of 250 bytes or less. Various embodiments may support cryptographic signing of beacon type messages using certificates. Various embodiments may include generating a beacon type message, cryptographically signing the beacon type message at least in part using a certificate to generate a signed beacon message, and sending the signed beacon type message in one or more broadcast transmissions in conjunction with, or independently of, certificate information used to verify the signed beacon message.

Abstract: A method for wireless communication performed by a user equipment (UE) includes determining whether a network slice-specific authentication and authorization (NSSAA) procedure is complete. The method also includes transmitting a protocol data unit (PDU) session request to attempt establishing a PDU session without providing an Single-NSSAI when the NSSAA procedure is complete. A method for wireless communications, by an access and mobility management function (AMF) includes determining whether all default network slices for a user equipment (UE) are subject to network slice-specific authentication and authorization (NSSAA). The method also initiates NSSAA on the default network slices when all default network slices are subject to NSSAA.

Abstract: The present disclosure generally relates to identifying, by a processor of a wireless communications device, a service, determining, by the processor and based at least in part on the service, whether to prioritize a type of connection gateway to utilize in connecting to the service, where the processor determines to prioritize the type of connection gateway, selecting, by the processor, a connection gateway for the service based at least in part on a stored network access preference for the service, where the processor determines not to prioritize the type of connection gateway, selecting, by the processor, the connection gateway for the service regardless of the stored network access preference for the service, and connecting, by the processor, to the service via the connection gateway.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station may signal one or more emission limits for one or more different frequency bands, and two or more values for one of the emission limits may be provided. A first subset of user equipments (UEs) may be capable of aerial operations (e.g., unmanned aerial vehicles (UAVs) or drones) and may use a first value of the first emission limit and the second subset of UEs may not capable of aerial operations and may use a second value of the first emission limit. A UE status such as altitude or position, or transmission directivity may also be used to determine if the UE is to apply the first value or the second value for an emission limit of a frequency band.
