Cross-resource subscription for M2M service layer
A subscriber issues a message to a resource host to request subscription to multiple resources. This message may indicate identifiers of these resources, event notification criteria for each individual resource and define cross-resource notification criteria such as time window type and time window size. The resource host issues cross-resource notifications to the subscriber or its designated notification targets when expected changes on the target resources occur within a time window.
1. An apparatus for resource subscription, the apparatus comprising:
a processor; and
a memory coupled with the processor, the memory comprising executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
receiving a message for a cross-resource subscription,
wherein the message is indicative of a request, by a remote device, for a subscription,
wherein the subscription is for the remote device to be notified of a change of a plurality of target resources;
based on the message, determining that the remote device has privilege to create the cross-resource subscription; and
based on having the privilege to create the cross-resource subscription, generating a local subscription resource for the cross-resource subscription.
2. The apparatus of claim 1 , wherein the message comprises a list of event notification criteria for the plurality of target resources.
3. The apparatus of claim 1 , wherein the message comprises a number of the plurality of target resources in which a notification is expected to be received when a criteria within a window of time are met.
4. The apparatus of claim 3 , wherein the message comprises an indication of a type of the window of time.
5. The apparatus of claim 3 , wherein the message comprises an indication of a type of the window of time, wherein the type of window of time comprises a sliding time window.
6. The apparatus of claim 3 , the operations further comprising:
providing a second request for a subscription to a first resource of the plurality of target resources, wherein the second request comprises a criterion of the criteria;
receiving a notification that the criterion of the criteria was met;
determining that the criteria is met based on receiving the notification; and
notifying the remote device based on the determining that the criteria is met.
7. The apparatus of claim 1 , the operations further comprising providing instructions to send a response message that comprises an indication of approval of cross-resource subscription.
8. The apparatus of claim 1 , wherein at least one resource of the target resources is located on the remote device.
9. The apparatus of claim 1 , wherein the apparatus comprises a common service entity.
10. An apparatus for resource subscription, the apparatus comprising:
a processor; and
a memory coupled with the processor, the memory comprising executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
transmitting a message for a cross-resource subscription,
wherein the message is indicative of a request for a subscription,
wherein the subscription is for the apparatus to be notified of a change of a plurality of target resources; and
receiving a response message that comprises an indication of approval of cross-resource subscription,
wherein the response message is sent after generating a local subscription resource for the cross-resource subscription based on determining that the apparatus has privilege to create the cross-resource subscription.
11. A method for resource subscription, the method comprising:
receiving, by a machine-to-machine entity, a message for a cross-resource subscription,
wherein the message is indicative of a request, by a remote device, for a subscription,
wherein the subscription is for the remote device to be notified of a change of a plurality of target resources;
based on the message, determining, by the machine-to-machine entity, that the remote device has privilege to create the cross-resource subscription; and
based on having the privilege to create the cross-resource subscription, generating, by the machine-to-machine entity, a local subscription resource for the cross-resource subscription.
12. The method of claim 11 , further comprising publishing an indication of information of the local subscription resource to a display.
13. The method of claim 11 , further comprising publishing parameters of the message for cross-resource subscription to a display.
14. The method of claim 11 , further comprising publishing, to a display, events that meet criteria within a graphical representation of a window of time.
15. The method of claim 14 , wherein the message comprises list of event notification criteria for the plurality of target resources.
16. The method of claim 14 , wherein the message comprises a number of the plurality of target resources in which notifications is expected to be received when the criteria are met.
17. The method of claim 14 , wherein the message comprises an indication of a type of the window of time.
18. The method of claim 14 , further comprising providing a second request for a subscription to a first resource of the plurality of target resources, wherein the second request comprises a criterion of the criteria.
19. The method of claim 11 , further comprising providing instructions to send a response message that comprises an indication of approval of cross-resource subscription.
20. The method of claim 11 , wherein at least one resource of the target resources is located on the remote device.
