  • Publication number: 20230188938
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio access network (RAN) node may transmit, to an access and mobility function (AMF) of a core network, a request associated with a location-based state of a user equipment (UE) served by the RAN node. For example, the location-based state of the UE may be associated with whether the UE is flying or whether the UE is driving. Accordingly, the RAN node may receive a message in response to the request. The RAN node may receive the message in response to the request from the AMF. Alternatively, the AMF may establish a connection between the RAN node and a location management function (LMF) of the core network such that the RAN node receives the message in response to the request from the LMF. Numerous other aspects are described.

  • Publication number: 20230180057
    Abstract: Techniques for managing access combinations for multiple access protocol data unit (PDU) sessions are described. A communication device may receive control signaling indicating a configuration for a multiple access PDU session associated with a plurality of access links. The plurality of access links may be associated with a first type of access, a second type of access, or a combination thereof. The communication device may select a mode for allocation of a data flow associated with the multiple access PDU session to the plurality of access links based at least in part on the received control signaling. The communication device may allocate the data flow associated with the multiple access PDU session to the plurality of access links based at least in part on the selected mode, and transmit the allocated data flow over the plurality of access links associated with the two types of access.

  • Publication number: 20230156464
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) associated with an unmanned aerial vehicle (UAV) in a cellular terrestrial network may establish a connection with a unified data management (UDM) entity for communications with an unmanned aerial system service supplier (USS). The UE, or an access and mobility management function (AMF), may receive a security configuration from the UDM entity in a non-access stratum transport message. The security configuration may include one or more security credentials that enable communications between the UE and the USS. The AMF may transmit an acknowledgement message indicating the UE successfully received the indication of the security configuration. The UDM may transmit a message to the USS based on receiving the acknowledgment message. The UE may transmit a registration request to the USS. The UE and the USS may communicate according to the security credentials of the security configuration.

  • Publication number: 20230156589
    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.

  • Publication number: 20230141754
    Abstract: Certain aspects of the present disclosure provide techniques for ensuring compatibility between network slice operating frequencies and user equipment (UE) radio capabilities. An example method generally includes receiving, from a network core entity, a request for information about capabilities of a user equipment (UE) and information about a plurality of network slices in an allowed set of network slices for the UE; identifying, based on UE capability information, a subset of the allowed set of network slices that the UE can use for communications between the UE and the network entity; generating a response including at least the subset of the allowed set of network slices that the UE can use for communications between the UE and the network entity; and transmitting the response to the network core entity.

  • Publication number: 20230131915
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine whether a geographic location code associated with a geographic location of the UE matches a geographic location code in a received message. Based on the determination, the UE may select a non-public network (NPN) function. Additionally or alternatively, a UE may discover or select an NPN function based on determining that legal requirements, such as one or more interception conditions, are independent of the geographic location of the UE. For example, the UE may discover and one or more NPN functions according to a query performed using an NPN function identifier or an NPN identifier. The UE may determine that the NPN function selection (e.g., for a geographic location of the UE) is independent of an interception condition (e.g., associated with the geographic location of the UE).
