Abstract: Aspects relate to delay management techniques to handle delays introduced by high latency links in non-terrestrial networks for non-access stratum (NAS) mobility management and session management procedures. The NAS timers within the user equipment (UE) and core network utilized for mobility management and session management procedures may be configured with different durations, such as a normal duration, an extended duration, or a reduced duration, based on whether the UE is connected to a terrestrial or non-terrestrial radio access network (RAN), one or more capabilities of the UE, and/or the various RAN types (e.g., terrestrial or non-terrestrial) within a registration area that the UE is located in.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to local area data network connectivity. In certain aspects, a method for use by a network device includes determining a set of available local area data networks (LADNs) for a user equipment (UE) based on a subscription of the UE to a set of data network names (DNNs) corresponding to the set of available LADNs and sending the UE information indicative of the set of available LADNs and a location of availability corresponding to each of the LADNs of the set of available LADNs.

Abstract: A method, operational at a device, includes receiving at least one packet belonging to a first set of packets of a packet flow marked with an identification value, determining that the at least one packet is marked with the identification value, determining to change a quality of service (QoS) treatment of packets belonging to the first set of packets marked with the identification value that are yet to be received, and sending a request to change the QoS treatment of packets belonging to the first set of packets marked with the identification value that are yet to be received to trigger a different QoS treatment of packets within the packet flow, responsive to determining to change the QoS treatment. Other aspects, embodiments, and features are also claimed and described.

Abstract: Techniques for modification of data sessions may allow changing of user plane functions (UPFs) that serve a data session. A UE may identify a user plane of a first data session is to be relocated from a first UPF, and may initiate a second data session with a second UPF using an identification associated with the first data session. In some cases, the first data session may be modified to be served by the second UPF rather than the first UPF. A network entity, such as a session management function (SMF) may determine that a user plane of a first data session of a UE is to be relocated away from a first UPF, and may perform a user plane relocation of the first data session via establishing a second data session at a second UPF or via modifying the first data session to be served by a second UPF.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may establish a PC5 unicast link with a second UE. The UE may transmit, to a second UE in a PC5 radio resource control (RRC) message, capability information that includes an indication that the first UE is an unmanned aerial vehicle (UAV). Numerous other aspects are described.

Abstract: In some examples, a user equipment (UE) obtains a connectivity in a first cell, the connectivity comprising a first type of connection that provides access to services in a local data network. The UE camps on a second cell, determines if the connectivity is not supported in the second cell based on broadcast information from the second cell, the broadcast information comprising information of the second cell, and in response to determining that the connectivity is not supported in the second cell, disconnect the connectivity, wherein the disconnecting comprises sending a Non Access Stratum (NAS) message via the second cell.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a network may establish a multiple access (MA) packet data unit (PDU) session for a local area data network (LADN) and may reconfigure a registration area to map to a LADN service area. A network may establish an MA PDU session for an LADN, but may steer traffic to only one of two access links. A network may reject a request for an MA PDU if it is for an LADN. A user equipment (UE) may be configured to trigger a UE registration update or other location information if it leaves an LADN service area while in an idle mode with one access network and a connected mode with the other access network. A UE may request LADN registration, and the network may provide the UE with an indication that MA PDU sessions for the LADN are not supported.

Abstract: Methods, systems, and devices for wireless communication are described. In one example, an aerial user equipment (UE) may receive an indication of a priority for cell selection for aerial UEs from each cell in a set of cells and may select a cell from the set of cells based on the priority of each cell in the set of cells. In another example, an aerial UE may connect to a network available to aerial UEs and non-aerial UEs for auxiliary communications, when appropriate. In yet another example, when an aerial UE transitions to a new mission status, the aerial UE may transmit a tracking area update (TAU) if the aerial UE is connected to a cell in a tracking area that does not support the new mission status. In yet another example, a base station may page an aerial UE based on a mission status of the aerial UE.

Abstract: Aspects of the disclosure relate to mechanisms for interworking between legacy and next generation radio access technologies (RATs) in a communication network. In some examples, a connectivity request originated by a user equipment towards a next generation core network may be processed by the next generation core network. The next generation core network may then provide the user equipment an indication of whether the next generation core network supports an inter-RAT handover between the next generation RAT and a legacy RAT.

Abstract: Certain aspects of the present disclosure provide techniques for selecting policies for routing of data traffic. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes selecting at least one policy for routing of data traffic to a network, wherein the policy comprise an access network discovery and selection policy (ANDSP) if the UE has the ANDSP provisioned regardless of whether the UE is registered to evolved packet core (EPC) or fifth-generation core network (5GCN), and communicating the data traffic to the network based on the selection.

Abstract: In some examples, a user equipment (UE) obtains a connectivity in a first cell, the connectivity identified by an access point name (APN), where the APN corresponds to a first type of connection, and where the first type of connection provides access to services in a local data network. The UE camps on a second cell, determines if the connectivity is not supported in the second cell based on broadcast information from the second cell, the broadcast information comprising information of the second cell, and in response to determining that the connectivity is not supported in the second cell, disconnect the connectivity, wherein the disconnecting comprises sending a Non Access Stratum (NAS) message via the second cell.

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: One aspect relates to initiating, by a device, a connection with an application server associated with one or more application services. A gateway derives an uplink network token and/or a downlink network token. The tokens are provisioned to the device and/or an application server over the user-plane. The tokens are included with uplink and/or downlink packets, respectively. Another aspect relates to receiving a data packet at a gateway. The gateway determines a requirement for a network token from the packet. The gateway derives the network token based on a device subscription profile maintained by a network. The network token may be sent with the packet to a destination address associated with the packet. A packet including a network token may be received at a gateway. The gateway may verify the network token and send the data packet to an application server or a device if the verifying is successful.

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: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for maximizing the potential of resources dedicated to aerial user equipment (UEs). In one example, a UE may receive signaling indicating that a cell supports communications exclusively with aerial UEs. The signaling may be used to bar non-aerial UEs from accessing the cell and reserve resources for communications with aerial UEs. In another example, a UE may receive signaling identifying one or more frequency bands dedicated to aerial UEs. The UE may then communicate on the one or more frequency bands. In yet another example, a UE may receive signaling indicating a set of aerial access categories supported by a cell. The signaling may be used to reserve resources for high-priority aerial UEs (e.g., aerial UEs used for law enforcement purposes).

Abstract: A gateway device detects a trigger associated with a device and, in response, identifies an application service associated with the device, obtains a traffic network policy associated with the application service, and obtains a network access token based on the traffic network policy. The network access token facilitates validating and/or mapping a downlink data packet obtained at the gateway device in user-plane traffic that is destined for the device. The network access token is sent to an entity in control-plane signaling. Subsequently, the gateway device obtains a downlink data packet including the network access token. The gateway device verifies the network access token and/or maps the downlink data packet to the device using data obtained from the network access token. The network access token may be removed from the downlink data packet before the downlink data packet is sent to the device according to the mapping.

Abstract: A user equipment (UE) may identify a bearer (e.g., a default bearer) and request establishment of a second bearer (e.g., a high priority bearer) for use in streaming downlink data from, for example, an application server. The UE may determine a status of a playout buffer and select the first bearer or the second bearer for use in streaming the downlink data associated with the application based on the status of the playout buffer. For example, the first bearer may be used be used by default, and the second bearer may be selected if the amount of data in the playout buffer does not satisfy (e.g., is below) a threshold. In some cases, each bearer may be associated with a transmission control protocol (TCP) port associated with a TCP connection. In some cases, each bearer may be associated with different Internet protocol (IP) address.
