Abrégé

Embodiments of this application provide a subscription update method, device, and system, so that a target subscription network element can learn an event notification of a subscription event in a timely manner in a scenario in which a terminal is migrated from a source subscription network element to the target subscription network element. The method includes: determining, by a first event notification network element, that a notification condition of a first subscription event of a first terminal is met; obtaining, by the first event notification network element, first callback address information of a target subscription network element; and sending, by the first event notification network element, a first message to the target subscription network element based on the first callback address information, where the first message carries an identifier of the first terminal and a first event notification of the first subscription event, and the identifier of the first terminal is used to correlate the first event notification with the first terminal.
