    Abstract: Disclosed is an AMBR control method, device, and system, so that a quality of service (QoS) control mechanism can be used to control use of resources in a network slice by a terminal device. The method includes: a mobility management network element obtaining M pieces of single network slice selection assistance information (S-NSSAI) corresponding to a terminal device and a first slice-AMBR corresponding to each piece of S-NSSAI in the M pieces of S-NSSAI; and sending the M pieces of S-NSSAI and the first slice-AMBR corresponding to each piece of S-NSSAI to an access network device, where the first slice-AMBR corresponding to each piece of S-NSSAI is used to determine a second slice-AMBR corresponding to the S-NSSAI, and the second slice-AMBR corresponding to each piece of S-NSSAI is used to control an aggregate bit rate of non-guaranteed bit rate non-GBR QoS flows in a network slice indicated by the S-NSSAI.

    Abstract: The present disclosure relates to quality of service (QoS) information notification methods, devices, and systems. In one example method, a user plane network element obtains a first QoS notification, where the first QoS notification includes first QoS information used to indicate QoS of a target service. The user plane network element sends first indication information to an application network element to which a QoS notification needs to be reported, where the first indication information is used to indicate a second QoS notification, the second QoS notification includes 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.
