Abstract: A data transmission method includes an access network apparatus that receives a data packet through a first protocol data unit PDU session. The first PDU session corresponds to a first data service task. When the first data service task is a data service task to be processed by the access network apparatus, the access network apparatus performs a first operation on first data based on the first data service task, to obtain second data; and sends the second data based on the first PDU session. Alternatively, when the first data service task is a data service task not to be processed by the access network apparatus, the access network apparatus forwards the data packet.

Abstract: This application provides a communication method for sensing and a communication apparatus. One example method includes: receiving first configuration information, where the first configuration information includes a first threshold, the first threshold indicates a sensing range of a first sensing entity for a service requirement of a first sensing service, the first threshold is determined based on the service requirement of the first sensing service, and the first sensing service is implemented based on sensing on a first sensing target by the first sensing entity; and determining, based on the first configuration information and position information of the first sensing target, another sensing entity to execute the first sensing service.

Abstract: In a communication method, an access network device sends a first request to an access and mobility management function (AMF), where the first request is used to request to establish a session between the access network device and a user plane function (UPF), and the first request includes identification information of the access network device. Then, the access network device receives, from a session management function (SMF) through the AMF, first configuration information for the session, where the first configuration information includes configuration information for an uplink channel from the access network device to the UPF.

Abstract: Disclosed are a data collection and processing method and an apparatus, which relate to the field of communication technologies. The method includes: obtaining a match table and an action set that are associated with a first communication apparatus; and sending, to the first communication apparatus, the match table and the action set that are associated with the first communication apparatus, where the first communication apparatus is an initial data agent apparatus in a data transmission process, the match table indicates collection and/or filtering processing on data obtained from a data source, the match table includes identification information of the first communication apparatus and a service identifier, and the action set indicates one or more actions associated with the service identifier.

Abstract: This application discloses a communication method and apparatus, to ensure transmission continuity of a data service corresponding to a data service task. In the method, a data control apparatus receives first information from a target network apparatus or a source network apparatus, where the first information is used to request to determine routing information of a data service task between a plurality of data processing apparatuses; and sends second information to the target network apparatus, where the second information is used to determine a next-hop data processing apparatus of the data service task after a first data processing apparatus.

Abstract: An identity management method, wherein the method includes: A trusted authority (TA) device determines a pseudonymous identity (PID) of a terminal device i, and sends a first parameter to the terminal device i, where the first parameter indicates the PID of the terminal device i, and the PID of the terminal device i is determined based on a real identity (RID) of the terminal device i. Based on this, the TA device may determine the PID for the terminal device, to protect the RID of the terminal device. In addition, the PID of the terminal device is associated with the RID of the terminal device, so that the TA device can determine the RID of the terminal device based on the PID of the terminal device, and can determine the real identity of the terminal device when the terminal device performs a malicious operation or an unauthorized operation.
