A location obtaining method includes requesting, from a network, to obtain locations of a first terminal device and a second terminal device at a same time point, and receiving the locations that are fed back by the network and that are of the first terminal device and the second terminal device at the same time point. The locations of the first terminal device and the second terminal device at the same time point are obtained.

Location obtaining method and apparatus thereof

A session management method performed by a session management network element includes receiving a first request message, where the first request message is used to request to establish a first session for a terminal, determining to establish the first session as an always-on session, where the always-on session is a session for which user-plane resources are activated when the terminal is transitioned from an idle mode to a connected mode, and sending a first response message to the terminal, where the first response message is used to indicate that the session management network element accepts to establish the first session, the first response message comprises first indication information, and the first indication information is used to indicate that the first session is an always-on session.

Session management method, apparatus, and system

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.

Method for detecting unauthorized uncrewed aerial vehicle, apparatus, and system

This application discloses a processing method of an abnormally behaving unmanned aerial vehicle, a network element, a system, and a storage medium, to detect a data packet for transmitting non-command and control (non-C2) data. According to the method, an SMF network element provides a first rule for a UPF network element, where the first rule indicates the UPF network element to detect, from a target transmission data packet, the data packet for transmitting the non-C2 data, and the target transmission data packet is a data packet between the UAV and the UAVC; the SMF network element receives a first session report sent by the UPF network element; and the SMF network element sends an abnormal traffic report to the first network element based on the first session report.

Processing method of abnormally behaving unmanned aerial vehicle, network element, system, and storage medium

Embodiments of this application provide a session processing method and apparatus. When a quantity of sessions of a terminal device that each have an activated user plane connection is not less than a quantity threshold, the terminal device determines to deactivate a user plane connection of at least one first session, where the sessions that each have the activated user plane connection include the at least one first session. The terminal device sends a first request message to a first network element, where the first request message includes indication information, and the indication information indicates to deactivate the user plane connection of the at least one first session.

Session processing method and communication apparatus

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.

Abnormal offline state determining method and related apparatus

Methods, systems, and apparatus for rate control are provided. In one aspect, a rate control method includes: receiving, by a control device, a connection establishment request from a terminal, the connection establishment request being for establishing a connection for the terminal to transmit data, and sending, by the control device, rate control time management information to a data sending device. The data sending device is configured to perform rate control over the data sent through the connection based on the time management information. The ratio control time management information includes start time indication information of a rate control time unit used for rate control, and the start time indication information indicates a start time of the rate control time unit.

Rate control method, apparatus, and system

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.
