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.
Claims12
A method implemented by a fourth network function network element and comprising:
- receiving, from a second network function network element, a first address of a first network function network element and a second address of a third network function network element when a network element serving a user equipment is handed over from the second network function network element to the fourth network function network element, wherein the second address is usable for sending a service to the third network function network element;
- and
- sending, to the first network function network element according to the first address, a message notifying the first network function network element that a subscription of the service by the first network function network element has changed.
A fourth network function network element comprising:
- at least one memory configured to store instructions;
- and
- at least one processor coupled to the at least one memory and configured to execute the instructions to cause the fourth network function network element to:
- receive, from a second network function network element, a first address of a first network function network element and a second address of a third network function network element when a network element serving a user equipment is handed over from the second network function network element to the fourth network function network element, wherein the second address is usable for sending a service to the third network function network element;
- and
- send, to the first network function network element according to the first address, a message notifying the first network function network element that a subscription of the service by the first network function network element has changed.
A computer program product comprising instructions that are stored on a non-transitory computer-readable medium and that, when executed by a processor, cause a fourth network function network element to:
- receive, from a second network function network element, a first address of a first network function network element and a second address of a third network function network element when a network element serving a user equipment is handed over from the second network function network element to the fourth network function network element, wherein the second address is usable for sending a service to the third network function network element;
- and
- send, to the first network function network element according to the first address, a message notifying the first network function network element that a subscription of the service by the first network function network element has changed.
A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause a fourth network function network element to:
- receive, from a second network function network element, a first address of a first network function network element and a second address of a third network function network element when a network element serving a user equipment is handed over from the second network function network element to the fourth network function network element, wherein the second address is usable for sending a service to the third network function network element;
- and
- send, to the first network function network element according to the first address, a message notifying the first network function network element that a subscription of the service by the first network function network element has changed.
