1. A quality of service (QOS) information notification method, comprising:
receiving, by a user plane network element, second indication information from a session management network element, wherein the second indication information indicates that a target service needs a user plane QoS notification;
obtaining, by the user plane network element, a first QoS notification, wherein the first QoS notification comprises first QoS information indicating QoS of the target service; and
sending, by the user plane network element based on the second indication information, first indication information to an application network element to which a QoS notification needs to be reported, wherein the first indication information indicates a second QoS notification, the second QoS notification comprises second QoS information of the target service, and the first QoS notification is the same as the second QoS notification, or the second QoS notification is determined based on the first QoS notification.
