Subscription information update method and apparatus
Provided are a method and apparatus for updating subscription information. The method includes steps described below. After a second NF transfers first subscription information to a third NF, where the first subscription information includes a first correlation identity allocated by the second NF to a first NF, the third NF allocates a second correlation identity to the first NF, and the third NF receives update subscription information of the first NF, where the update subscription information includes the second correlation identity. By using the above scheme, the issue of the lack of an update scheme of the subscription information adaptable a new system in the related art is resolved, and the update scheme of the subscription information adaptable the new system is proposed, for example, when across-NF registration of the user terminal is generated, the subscription message is updated between the new third NF and the first NF in time.
1. A method for updating subscription information, comprising:
receiving, by a new net function (NF), first subscription information sent by an old NF;
allocating, by the new NF, responsive to receiving the first subscription information sent by the old NF, a new correlation identity to a consumer NF, wherein the consumer NF subscribes to an event of a user equipment (UE);
sending, by the new NF, the new correlation identity to the consumer NF; and
receiving, by the new NF, an update subscription message of the consumer NF, wherein the update subscription message comprises the new correlation identity.
2. The method of claim 1 , wherein the step of sending the new correlation identity further comprises sending, by the new NF to the consumer NF, a notification message carrying the new correlation identity.
3. The method of claim 1 , wherein the first subscription information comprises an old correlation identity allocated by the old NF to the consumer NF.
4. The method of claim 1 , further comprising: sending, by the new NF to the consumer NF, at least one of the following information: an identity (ID) of the new NF, a subscription event in the first subscription information, or target content of the consumer NF indicated by the first subscription information.
5. The method of claim 1 , wherein following the step of receiving the first subscription, the method further comprises canceling, by the old NF, a subscription relationship between the consumer NF and the old NF.
6. A method for updating subscription information, comprising:
establishing, by a consumer net function (NF), a subscription relationship with an old NF;
receiving, by the consumer NF, a new correlation identity allocated by a new NF, responsive to the new NF receiving first subscription information carrying the subscription relationship sent by the old NF, wherein the consumer NF subscribes to an event of a user equipment (UE); and
sending, by the consumer NF, an update subscription message to the new NF, wherein the update subscription message comprises the new correlation identity.
7. The method of claim 6 , wherein the step of receiving a new correlation identity further comprises receiving, by the consumer NF, a notification message carrying the new correlation identity sent by the new NF.
8. The method of claim 6 , further comprising: receiving, by the consumer NF from the new NF, at least one of the following information: an identity (ID) of the new NF, a subscription event in the first subscription information, or target content of the consumer NF indicated by the first subscription information.
9. A device for updating subscription information, comprising a memory and a processor, wherein the memory is configured to store a computer program, and the processor is configured to:
receive, via a new net function (NF), first subscription information sent by an old NF;
allocate, via the new NF responsive to receiving the first subscription information sent by the old NF, a new correlation identity to a consumer NF, wherein the consumer NF subscribes to an event of a user equipment (UE);
send, via the new NF, the new correlation identity to the consumer NF; and
receive, via the new NF, an update subscription message of the consumer NF, wherein the update subscription message comprises the new correlation identity.
10. The device of claim 9 , wherein the step of sending the new correlation identity further comprises sending, by the new NF to the consumer NF, a notification message carrying the new correlation identity.
11. The device of claim 9 , wherein the first subscription information comprises an old correlation identity allocated by the old NF to the consumer NF.
12. The device of claim 9 , wherein the processor is further configured to send, via the new NF to the consumer NF, at least one of the following information: an identity (ID) of the new NF, a subscription event in the first subscription information, or target content of the consumer NF indicated by the first subscription information.
13. The device of claim 9 , wherein the processor is further configured to cancel, via the old NF, a subscription relationship between the consumer NF and the old NF, following the step of receiving the first subscription.
14. A device for updating subscription information, comprising a memory and a processor, wherein the memory is configured to store a computer program, and the processor is configured to execute:
establish, via a consumer net function (NF), a subscription relationship with an old NF;
receive, via the consumer NF, a new correlation identity allocated by a new NF, responsive to the new NF receiving first subscription information carrying the subscription relationship sent by the old NF, wherein the consumer NF subscribes to an event of a user equipment (UE); and
send, via the consumer NF, an update subscription message to the new NF, wherein the update subscription message comprises the new correlation identity.
15. The device of claim 14 , wherein the processor is further configured to receive, via the consumer NF, a notification message carrying the new correlation identity sent by the new NF.
16. The device of claim 14 , wherein the processor is further configured to receive, via the consumer NF from the new NF, at least one of the following information: an identity (ID) of the new NF, a subscription event in the first subscription information, or target content of the consumer NF indicated by the first subscription information.
