Abstract

A service subscription method and an apparatus for reporting a service change, where the method includes a first network function network element sending the address of the first network function network element to a second network function network element. Therefore, when a first service changes, the first network function network element can receive a notification.

Claims

1. A method for subscribing service, comprising:

sending, by a first network function network element, a first message to a second network function network element, wherein the first network function network element sends the first message to subscribe to a first service on behalf of a third network function network element, wherein the first service is provided by the second network function network element, and wherein the first message comprises a first address of the first network function network element; and

sending, by a fourth network function network element when there is a change from the second network function network element to the fourth network function network element, a third message to the first network function network element, wherein the fourth network function network element sends the third message according to the first address to notify the first network function network element that a subscription of the first service has changed.

2. The method according to claim 1, further comprising sending, by the second network function network element, context information to the fourth network function network element, wherein the context information comprises the first address.

3. The method according to claim 1, further comprising:

allocating, by the second network function network element, a subscription correlation identifier; and

sending, by the second network function network element, the subscription correlation identifier to the first network function network element.

4. The method according to claim 3, further comprising allocating, by the fourth network function network element, a new subscription correlation identifier, wherein the third message further comprises the new subscription correlation identifier.

5. The method according to claim 4, wherein the third message further comprises a subscription correlation identifier change event identifier.

6. The method according to claim 1, wherein the first message further comprises a second address of the third network function network element.

7. The method according to claim 6, further comprising:

receiving, by the first network function network element, a second message from the third network function network element, wherein the second message is for subscribing to a second service, and wherein the second message comprises the second address of the third network function network element; and

determining, by the first network function network element based on the second service, the first service that needs to be subscribed to from the second network function network element.

8. The method according to claim 6, further comprising providing, by the second network function network element, the first service to the third network function network element according to the second address of the third network function network element.

9. The method according to claim 1, wherein the first address is a notification endpoint of the first network function network element.

10. A system comprising:

a second network function network element;

a third network function network element;

a fourth network function network; and

a first network function network element configured to;

send a first message to the second network function network element to subscribe to a first service on behalf of the third network function network element, wherein the first service is provided by the second network function network element, and wherein the first message comprises a first address of the first network function network element; and

receive a third message from the fourth network function network element to notify the first network function network element that a subscription of the first service has changed,

wherein the fourth network function network element is configured to send the third message according to the first address when there is a change from the second network function network element to the fourth network function network element.

11. The system according to claim 10, wherein the second network function network element is configured to send context information to the fourth network function network element, and wherein the context information comprises the first address.

12. The system according to claim 10, wherein the second network function network element is configured to:

allocate a subscription correlation identifier; and

send the subscription correlation identifier to the first network function network element.

13. The system according to claim 12, wherein the fourth network function network element is further configured to allocate a new subscription correlation identifier, and wherein the third message further comprises the new subscription correlation identifier.

14. The system according to claim 13, wherein the third message further comprises a subscription correlation identifier change event identifier.

15. The system according to claim 10, wherein the first message further comprises a second address of the third network function network element.

16. The system according to claim 15, wherein the third network function network element is configured to send a second message to the first network function network element.

17. The system according to claim 15, wherein the second network function network element is configured to provide the first service to the third network function network element according to the second address.

18. The system according to claim 10, wherein the first address is a notification endpoint of the first network function network element.

19. The system according to claim 16, wherein the second message is used to subscribe to a second service, and wherein the second message comprises the second address.

20. The system according to claim 19, wherein the first network function network element is configured to determine, based on the second service, the first service that needs to be subscribed to from the second network function network element.
