Abstract: This application provides a reflective QoS flow characteristic-based communications method and apparatus. In the method, an access-network network element sends first information to a core-network network element, where the first information is used to indicate whether a data packet has a reflective QoS flow characteristic; and the access-network network element determines, based on the first information, whether there is a need to send a QoS flow identifier to a terminal. In this way, signaling overheads are reduced.

Abstract: Embodiments of this application disclose a communication method and a related apparatus, to position a terminal device by a positioning device. A first access network device sends a retrieve UE context request message to a source access network device. The first access network device receives a retrieve UE context response message from the source access network device. The retrieve UE context response message includes reference information used to configure a sounding reference signal SRS of a terminal device, and/or information used to indicate to configure an SRS for the terminal device. The terminal device is in inactive state. The first access network device determines SRS configuration information of the terminal device based on the reference information and/or the information used to indicate to configure the SRS for the terminal device. The first access network device sends the SRS configuration information to the terminal device.
