Abstract: Embodiments of this application provide a QoS flow processing method and device, and a communications system. A first access network device sends a message used for a service transfer request to a second access network device, and the message used for the service transfer request includes configuration information of a QoS flow in the first access network device, so that the second access network device can configure a mapping relationship from the QoS flow to a DRB of the second access network device for UE based on the configuration information, and accept the QoS flow of the UE. Therefore, in a service transfer process, a reliable QoS service can be provided for a user, and continuity of a user service can be ensured.

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.
