The first session management network element sends second report information, which includes second indication information and an identifier of a first alternative service requirement, to an application function network element. The identifier of the first alternative service requirement corresponds to the identifier of the first alternative QoS profile. The second indication information indicates that a QoS requirement of a first service data flow cannot be guaranteed. The first QoS flow is configured to transmit the first service data flow, which is a service data flow of an application corresponding to the application function network element.

An event report sending method in which a session management network element receives an event notification request from a policy control network element, where the event notification request includes an event identifier and a notification address for receiving an event report of an event report receiving network element, and where the event report receiving network element is an application function network element or a network exposure function network element. The session management network element sends, a first message comprising the event identifier and the notification address to a user plane network element, where the first message indicates to the user plane network element to send, to the notification address, a first event report corresponding to the event identifier. Thus, the network exposure function network element sends the received first event report to the application function network element, such that the application function network element obtains the event report.
