Abstract
A subscription update method, device, and system, where the method is performed by a first event notification network element and includes: determining that a notification condition of a first subscription event of a first terminal is met; obtaining first callback address information of a target subscription network element; and sending 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.
Claims20
A subscription update method comprising:
- receiving, by a first event notification network element, a request from a source subscription network element, wherein the request subscribes to a first subscription event, and wherein the request comprises first callback address information comprising information about the source subscription network element;
- determining, by the first event notification network element, that the source subscription network element does not serve a first terminal;
- obtaining, by the first event notification network element, information about a target subscription network element;
- substituting, by the first event notification network element, the information about the target subscription network element for the information about the source subscription network element in the first callback address information to obtain second callback address information;
- sending, by the first event notification network element, a first event notification of the first subscription event to the target subscription network element based on the second callback address information;
- and
- receiving, by the target subscription network element, the first event notification of the first subscription event.
A subscription update system, comprising:
- a first event notification network element, wherein the first event notification network element comprises at least one processor and a memory having computer readable instructions stored thereon that, when executed by the at least one processor, cause the first event notification network element to:
- receive a request from a source subscription network element, wherein the request subscribes to a first subscription event, wherein the request comprises a first callback address information comprising information about the source subscription network element;
- determine that the source subscription network element does not serve a first terminal;
- obtain information about a target subscription network element;
- substitute the information about the target subscription network element for the information about the source subscription network element in the first callback address information to obtain a second callback address information;
- and
- send a first event notification of the first subscription event to the target subscription network element based on the second callback address information of the target subscription network element;
- and
- the target subscription network element configured to receive the first event notification of the first subscription event.
