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.

A session management method includes obtaining, by a terminal, terminal media access control (MAC) address information related to an existing Ethernet session of the terminal. The method also includes determining, by the terminal based on the terminal MAC address information related to the existing Ethernet session of the terminal, that a new Ethernet session needs to be established for the terminal. The method further includes initiating, by the terminal, establishment of the new Ethernet session for the terminal.

Session management method and system, and device

A route configuration method includes that after a first terminal moves out of a service scope of a user plane function (UPF) that currently provides a service for the first terminal, a first session management function (SMF) inserts a first intermediate UPF (I-UPF) into a user plane path of the first terminal, and configures, for the first I-UPF, a first routing rule corresponding to a second terminal. The first routing rule is used to send a packet whose destination address information is address information of the second terminal to a second anchor UPF (A-UPF). Therefore, a packet with a destination address information that is the address information of the second terminal can be directly forwarded by the first I-UPF to the first A-UPF, instead of being forwarded by the first I-UPF to the second A-UPF through the first A-UPF.

The technology of this application relates to a communication method and apparatus, to resolve a current problem that limited bandwidth resources of a single link affect quality of service. In an example embodiment, a terminal sends a first access message to an access gateway in a second core network through a first network, and sends a second access message to the access gateway through a second network, where the first access message is encapsulated by using a first IP address. Further, the access gateway requests an AMF network element to establish two communication links for the terminal. One communication link is for the terminal to access the core network through the first network, and the other communication link is for the terminal to access the core network through the second network. Through establishment of the two communication links between the terminal and the core network, bandwidth resources can be added, and the quality of service can be improved.

The AMF sends a state identifier of the abnormal offline state to an unmanned aircraft system traffic management network element (UTM). Therefore, the location information when the uncrewed aerial vehicle enters or leaves the offline state is used to determine whether the uncrewed aerial vehicle is in the abnormal offline state, so that accuracy of determining the abnormal offline state of the uncrewed aerial vehicle can be improved to some extent.
