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.

Abstract: This application provides a network node selection method and apparatus. An SMF network element obtains transmission capability information of an access network device, and selects, for a terminal device based on the transmission capability information of the access network device, a UPF network element that supports at least one transmission capability included in the transmission capability information. In this process, the SMF network element obtains a transmission capability of the access network device, and selects the UPF network element based on the transmission capability of the access network device. The selected UPF network element supports the transmission capability used by the access network device, so that data can be successfully transmitted between the access network device and the UPF network element. Therefore, a data transmission success rate is improved.

Abstract: A data communication method, a communication system, and related devices are configured to establish a transaction identifier (TI) in a user equipment (UE). The data communication method includes the following steps. A mobility management entity (MME) receives a request message and obtains ability information of the UE. If the UE has an ability to access a Universal Terrestrial Radio Access Network/GSM/EDGE Radio Access Network (UTRAN/GERAN), the MME generates the TI. A communication system and related devices are also provided. Thus, the TI is effectively established in the UE, so as to ensure normal processing of the UE.
Abstract translation: 数据通信方法，通信系统和相关设备被配置为在用户设备（UE）中建立交易标识符（TI）。 数据通信方法包括以下步骤。 移动性管理实体（MME）接收请求消息并获得UE的能力信息。 如果UE具有访问通用陆地无线电接入网/ GSM / EDGE无线电接入网（UTRAN / GERAN）的能力，则MME生成TI。 还提供通信系统和相关设备。 因此，在UE中有效地建立了TI，以确保UE的正常处理。
