1. A report information sending method, comprising:
receiving, by a first session management network element, first report information from a user plane network element, wherein the first report information comprises first indication information and an identifier of a first alternative quality of service (QOS) profile, and the first indication information indicates that a QoS requirement of a first QoS flow cannot be guaranteed; and
sending, by the first session management network element, second report information directly to an application function network element, wherein the second report information comprises second indication information and an identifier of a first alternative service requirement, 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, and the first service data flow is a service data flow of an application corresponding to the application function network element,
wherein, before the receiving, by the first session management network element, the first report information from the user plane network element, the method further comprises:
receiving, by the first session management network element, a first policy from a second session management network element, wherein
the first policy comprises an identifier of the first QoS flow, first QoS notification control indication information, at least one alternative QoS profile, information about a notification endpoint of the application function network element, and an identifier that is of at least one alternative service requirement and that corresponds to an identifier of the at least one alternative QoS profile,
the at least one alternative QoS profile comprises the first alternative QoS profile,
the identifier of the at least one alternative service requirement comprises the identifier of the first alternative service requirement, and
the first QoS notification control indication information indicates to send indication information indicating that the QoS requirement of the first QoS flow cannot be guaranteed; and
either
determining, by the first session management network element, a second policy according to the first policy, and sending, by the first session management network element, the second policy to a first access network element, wherein the second policy comprises the identifier of the first QoS flow, second QoS notification control indication information, and the at least one alternative QoS profile, and the second QoS notification control indication information is determined based on the first QoS notification control indication information, or
determining, by the first session management network element, a third policy according to the first policy, and sending, by the first session management network element, the third policy to the user plane network element, wherein the third policy indicates the user plane network element to send indication information indicating whether the QoS requirement of the first QoS flow can be guaranteed.
