Information notification method, apparatus, and system

1. An information notification method performed by a first entity, the method comprising:

receiving a creation request which comprises information for indicating a first resource feature from a second entity;

determining the first resource feature, wherein the first resource feature comprises a resource relationship and a resource type, and wherein the resource relationship is used to represent a connection relationship between resources and other various resources, and the resource type is used to represent a type of the resources and the other various resources;

receiving a resource operation request or a resource creation request transmitted by a third entity;

determining the resources in response to receiving the resource operation request or the resource creation request transmitted by the third entity;

determining whether a structure of the resources satisfies the resource relationship and the resource type; and

transmitting a notification message to the second entity if the structure of the resources satisfies the resource relationship and the resource type,

wherein before transmitting the notification message to the second entity, the method further comprises:

creating a second subscribed resource in the resources if the structure of the resources satisfies a reference resource feature; and

transmitting the notification message to the second entity comprises: transmitting the notification message to the second entity according to the second subscribed resource.

2. The method according to claim 1 , wherein the first resource feature is one or more resource structures.

3. The method according to claim 1 , wherein the first resource feature is one or more resource structures, and determining whether a structure of resources satisfies the resource relationship and the resource type comprises:

determining whether the structure of the resources satisfies any of the one or more resource structures.

4. The method according to claim 1 , wherein the first resource feature is one or more resource structures described by at least one semantic descriptor, and

determining whether a structure of resources satisfies the resource relationship and the resource type comprises:

determining whether the structure of the resources satisfies any of the one or more resource structures.

5. The method according to claim 1 , wherein

the first resource feature is at least one index which points to one or more resource structures, and

determining whether a structure of resources satisfies the resource relationship and the resource type comprises:

determining whether the structure of the resources satisfies any of the one or more resource structures.

6. The method according to claim 1 , wherein

the first resource feature is at least one index, which points to one or more resource structures described by at least one resource descriptor, and

determining whether a structure of resources satisfies the first resource feature comprises:

determining whether the structure of the resources satisfies any of the one or more resource structures.

7. The method according to claim 1 , wherein before determining the first resource feature, the method further comprises:

creating a first subscribed resource which comprises the information for indicating the first resource feature; and

determining a first resource feature comprises:

determining the first resource feature according to the first subscribed resource.

8. The method according to claim 7 , wherein after creating the first subscribed resource, the method further comprises:

setting an enabling attribute of the first subscribed resource to be true.

9. The method according to claim 7 , wherein the resource operation request comprises a resource acquisition request, a resource update request, a resource notification request, a resource discovery request, or a resource deletion request.

10. The method according to claim 1 , wherein after transmitting the notification message to the second entity, the method further comprises:

creating a second subscribed resource in the resources; and

transmitting a notification message to the second entity according to the second subscribed resource when the resources are changed.

11. The method according to claim 7 , wherein creating the first subscribed resource comprises:

creating the first subscribed resource according to the creation request.

12. The method according to claim 9 , wherein creating the first subscribed resource comprises:

creating the first subscribed resource according to the creation request.

13. An information notification device for a first entity, the information notification device comprising:

a processor;

a memory, configured to be coupled to the processor and to store instructions that, when executed on the processor, cause the processor to be configured to:

receive a creation request which comprises information for indicating a first resource feature from a second entity;

determine the first resource feature, wherein the first resource feature comprises a resource relationship and a resource type, and wherein the resource relationship is used to represent a connection relationship between resources and other various resources, and the resource type is used to represent a type of the resources and the other various resources;

receive a resource operation request or a resource creation request transmitted by a third entity;

determine the resources in response to receiving the resource operation request or the resource creation request transmitted by the third entity;

determine whether a structure of the resources satisfies the resource relationship and the resource type; and

transmit a notification message to the second entity when the structure of the resources satisfies the resource relationship and the resource type,

wherein before transmit the notification message to the second entity, the processor is further configured to:

create a second subscribed resource in the resources if the structure of the resources satisfies a reference resource feature; and

transmit the notification message to the second entity comprises: transmitting the notification message to the second entity according to the second subscribed resource.
