  • Publication number: 20220051570
    Abstract: Embodiments of this application provide a method for detecting an unauthorized uncrewed aerial vehicle, an apparatus, and a system. An AMF sends a tracking indication message to a network device, where the tracking indication message is used to indicate to report attribute information of user equipment in a coverage area of the network device when the attribute information of the user equipment meets a preset condition; and obtains the attribute information of the user equipment. In this way, after the attribute information of the user equipment is obtained, an identity status of the user equipment may be identified based on the attribute information of the user equipment, that is, whether the user equipment is an unauthorized uncrewed aerial vehicle is identified. This implements detection on an unauthorized uncrewed aerial vehicle that has accessed the 3GPP network.

  • Publication number: 20210321468
    Abstract: A communication method and apparatus. According to the communication method, a session management function (SMF) receives a first message sent by a first terminal apparatus. The first message is used to request the SMF to establish a first session for the first terminal apparatus. The first message is further used to indicate that the first session is used for communication between the first terminal apparatus and a second terminal apparatus. The first terminal apparatus and the second terminal apparatus belong to a same unmanned aerial vehicle communication system. Then, the SMF sends address information of the first terminal apparatus to a first management network element based on the first message. This provides a possibility of exchanging address information of terminal apparatuses in an unmanned aerial vehicle communication system.
