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: The present disclosure relates to a notification method. In one example method, a first base station configures a first cell identity for a first cell. The first cell identity comprises a first identifier field and a second identifier field. A reserved bit in the second identifier field and the first identifier field identify the first base station. A remaining bit in the second identifier field identifies the first cell. The first base station notifies a second base station or a core network device of a part of the first cell identity that identifies the first base station.
