Abstract: Disclosed are techniques for wireless communication using satellite access to a wireless network, where a wireless cell supported by a satellite is moving or temporarily fixed. In an aspect, a radio access network (RAN) entity or a user equipment (UE) provides, to a core network entity, an enhanced cell global identifier (CGI), where the enhanced CGI includes at least one field representing a location of the UE. Based on the enhanced CGI, the core network entity determines a location of the UE, and may provide a service to the UE based on the location. A core network may also provide an enhanced CGI to a RAN, e.g., to support wireless emergency alerting to UEs.

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: 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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor one or more first conditions pertaining to non-cellular communications between the UE and a non-cellular network while the UE is operating in a dual networking mode for steering, switching, or splitting traffic (e.g., an access traffic steering, switching, and splitting (ATSSS) mode) between the non-cellular network and a cellular network. The UE may predict an availability status of at least the non-cellular network based on at least one of the one or more first conditions. In some cases, the UE may determine whether to change dual networking modes based on the availability status and may communicate in accordance with the same or a different dual networking mode using at least one of the cellular network, the non-cellular network, or a combination thereof based on the prediction.

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: Certain aspects of the present disclosure relate to methods and apparatus for handling mobility between areas with heterogeneous network slices in wireless communications systems operating according to new radio (NR) technologies. An exemplary method that may be performed by a UE includes receiving an indication that a network slice is not available, entering a connection management idle (CM-IDLE) state, and initiating a registration procedure with an access and mobility management function (AMF) subsequent to entering the CM-IDLE state.

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: 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: 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.
