Abstract: This application provides a slice information update method and an apparatus. The method includes: when determining that a network slice that was not supported by a PLMN is updated to be supported by the PLMN, sending, by a network slice selection network element, a notification message to a communications network element, where the notification message is used to indicate that the PLMN supports the network slice; and notifying, by the communications network element, a terminal that the PLMN currently supports the network slice. In this way, the corresponding terminal learns that the PLMN currently supports the network slice.

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.
