Abstract

According to one aspect of the present disclosure, a method of wireless communication of a network element is provided. The method may include initiating a network slice specific authentication and authorization (NSSAA) procedure to register a user equipment (UE) with a network slice associated with uncrewed aerial services. In response to successful registration of the UE with the network slice by the NSSAA procedure, the method may include initiating an uncrewed aerial system (UAS) service supplier (USS) uncrewed aerial vehicle (UAV) authentication and authorization (UUAA) mobility management (UUAA-MM) procedure to register the UE with a USS associated with the network slice. In some embodiments, the USS may maintain the uncrewed aerial services.

Claims (15)

  1. A method of wireless communication of a network element, comprising: initiating a network slice specific authentication and authorization (NSSAA) procedure to register a user equipment (UE) with a network slice associated with uncrewed aerial services; and in response to successful registration of the UE with the network slice by the NSSAA procedure, initiating an uncrewed aerial system (UAS) service supplier (USS) uncrewed aerial vehicle (UAV) authentication and authorization (UUAA) mobility management (UUAA-MM) procedure to register the UE with a USS associated with the network slice; wherein a UUAA determination procedure is performed prior to the NSSAA procedure.
  2. The method of claim 1, further comprising: receiving, from the UE, a registration request to register with an access network, the registration request indicating support for the NSSAA procedure; and initiating a primary authentication procedure to register the UE with the access network based on the registration request, wherein the NSSAA procedure is initiated in response to the registration request indicating support for the NSSAA procedure, and wherein the registration request comprises one or more of single network slice selection assistance information (S-NSSAI) associated with the network slice or a civil aviation administration (CAA)-level UAV identification (ID) assigned to the UE by the USS.
  3. The method of claim 2, further comprising: when the registration request indicates support for NSSAA, initiating the NSSAA procedure concurrent with the primary authentication procedure or after the UE is registered with the access network.
  4. The method of any one of claims 1-3, wherein the UUAA determination procedure indicates performing the UUAA-MM procedure based on one or more of the following criteria: uncrewed aerial subscription data for the UE is valid; local operator policy indicates the UUAA determination procedure is performed during the primary authentication procedure; there is no valid UUAA result from a previous UUAA-MM procedure; and/or CAA-level UAV ID is provided in an initial registration request.
  5. The method of any one of claims 2-4, further comprising: in response to determining to perform the UUAA-MM procedure by the UUAA determination procedure, sending a registration accept message that includes a pending UUAA-MM indication to the UE; and receiving a registration complete message from the UE after sending the registration accept message.
  6. The method of any one of claims 1-5, further comprising: maintaining a UUAA result associated with the UE and the UUAA-MM procedure; and in response to the UE being successfully registered with the USS by the UUAA-MM procedure, initiating a UE configuration update procedure.
  7. The method of any one of claims 1-6, wherein the network element communicates with the USS via a UAS-network function (UAS-NF) during the UUAA-MM procedure.
  8. The method of any one of claims 1-7, wherein: the UE comprises a UAV, and the network element comprises an access and mobility management function (AMF).
  9. An apparatus configured to perform the method of any one of claims 1-8.
  10. A method of wireless communication of a user equipment (UE), comprising: sending, to a network element, a registration request to register with an access network, the registration request indicating support for a network slice specific authentication and authorization (NSSAA) procedure; performing a primary authentication procedure to register with the access network; in response to successful registration with the access network by the primary authentication procedure, performing the NSSAA procedure to register with a network slice that supports uncrewed aerial services; and in response to successful registration with the network slice by the NSSAA procedure, performing an uncrewed aerial system (UAS) service supplier (USS) uncrewed aerial vehicle (UAV) authentication and authorization (UUAA) mobility management (UUAA-MM) procedure to register with a USS associated with the network slice; wherein a UUAA determination procedure is performed prior to the NSSAA procedure.
  11. The method of claim 10, wherein the registration request indicates support for NSSAA.
  12. The method of claim 10 or 11, wherein the registration request comprises one or more of single network slice selection assistance information (S-NSSAI) associated with the network slice or a civil aviation administration (CAA)-level UAV identification (ID) assigned to the UE by the USS.
  13. The method of any one of claims 10-12, further comprising: receiving a registration accept message that includes a pending UUAA-MM indication from the network element; and sending a registration complete message to the network element after receiving the registration accept message.
  14. The method of any one of claims 10-13, wherein: the UE comprises a UAV, and the network element comprises an access and mobility management function (AMF).
  15. An apparatus configured to perform the method of any one of claims 10-14.
