Subscription and notification service
Mechanisms for subscription and notification may include dynamically changing notification behavior based on notification target status or support access to notification history information.
1. An apparatus with a subscription and notification service, 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 subscription request from a subscriber device to a first resource, wherein the subscription request comprises:
an event notification criteria that defines when a subscription and a notification service is to generate notification events, and
instructions on which statistical information about the notification events should be calculated and maintained;
detecting the event notification criteria has been met for the first resource;
generating an event notification for the first resource;
transmitting a notification message to the notification target;
calculating and recording notification statistical information based on instruction in the subscription request;
receiving a retrieval request to retrieve the notification statistical information; and
based on the retrieval request, sending a response, wherein the response comprises the recorded notification statistical information.
2. The apparatus of claim 1 , wherein the subscription request may comprise the time window of calculating the notification statistical information.
3. The apparatus of claim 1 , wherein the subscription request may comprise the list of notification targets whose notification statistics is to be calculated.
4. The apparatus of claim 1 , wherein the statistical information may comprise the number of successfully received notifications by a notification target.
5. The apparatus of claim 1 , wherein the statistical information may comprise the number of unsuccessful notifications sent to a notification target.
6. The apparatus of claim 1 , the operations further comprising:
obtaining a request from the subscriber to adjust notification targets; and
sending a response to the subscriber that comprises the result of the adjustment.
7. An apparatus, 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:
sending a subscription request for a first resource to the service layer, wherein the subscription request comprises:
an event notification criteria that defines when a subscription and a notification service is to generate notification events, and
instructions on which statistical information about the notification events should be calculated and maintained;
sending a retrieval request to retrieve the notification statistical information; and
receiving a response comprising the requested notification statistical information.
8. The apparatus of claim 7 , the operations further comprising:
based on the received notification statistical information, determining an adjustment to notification targets; and
sending a request to adjust notification targets.
9. A method comprising:
sending a subscription request for a first resource to the service layer, wherein the subscription request comprises:
an event notification criteria that defines when a subscription and a notification service is to generate notification events, and
instructions on which statistical information about the notification events should be calculated and maintained;
sending a retrieval request to retrieve the notification statistical information; and
receiving a response comprising the requested notification statistical information.
10. The method of claim 9 , the method further comprising:
based on the received notification statistical information, determining an adjustment to notification targets; and
sending a request to adjust notification targets.
