Abstract: 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.

Abstract: This application discloses an abnormal offline state determining method and a related apparatus. The method includes: An access and mobility management function network element (AMF) obtains location information when an uncrewed aerial vehicle enters or leaves an offline state. If a location indicated by the location information is outside a target offline area, the AMF marks a state of the uncrewed aerial vehicle as an abnormal offline state. 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.

Abstract: A communication method includes that a first terminal learns, based on first quality of service (QoS) status information of multicast communication provided by a second terminal, that a range between the first terminal and the second terminal is greater than a first communication range threshold in QoS requirement information of multicast communication in a multicast group, and accordingly adjusts the first communication range threshold to a second communication range threshold having a larger value, to adjust a QoS requirement of multicast communication between the first terminal and the second terminal.
