Abstract: Embodiments of the present disclosure relate to a data transmission method, user equipment, and a control plane node. User equipment (UE) determines a security attribute of a session of the UE; the UE sends a session establishment request message to a control plane node when the security attribute of the session of the UE does not meet a security requirement of an application. The session establishment request message is used to request to establish a session corresponding to the security requirement of the application. Embodiments of the disclosed method reduce an unnecessary signaling exchange caused by establishment of a new session in a data transmission process to facilitate meeting requirements of different services.

Abstract: This application provides an information transmission method, an apparatus, and a system. The method includes: A sensing network element receives location information of a first area from a first network element. The sensing network element receives first sensing data from a first device, where a sensing area corresponding to the first sensing data includes the first area, and the first device is configured to perform sensing. The sensing network element determines first information based on the location information of the first area and the first sensing data, where the first information indicates that a first terminal device is located in the first area. The sensing network element sends the first information to the first network element. Therefore, whether a terminal device is in the first area may be determined based on sensing data. This reduces signaling overheads.

Abstract: This application provides a UE sensing method and a communication apparatus. An SF network element, an NEF network element, an AMF network element, an SMF network element, a RAN network element, or the like may perform sensing detection on UE for a sensing requester or the UE, and provide a corresponding sensing service for the sensing requester or the UE. In some implementations, the sensing requester may be the UE, or may be an application function AF. Usually, the AF may directly request the sensing service from a communication system (for example, a 5GS), and the UE may request the sensing service from a communication system (for example, a 5GS), may perform sensing by directly requesting a sensing resource from the RAN network element based on a sensing requirement of the UE, or may perform sensing in collaboration with the RAN network element, and obtain sensing data, so that the sensing data can be quickly and efficiently obtained. In addition, in some implementations, not only sensing on the UE can be implemented, but also security and privacy on a UE side can be protected.
