Asynchronous calls using intermittent callback for delay sensitive applications
View Patent ↗A call handling system receives an asynchronous call request, from a call requester, requesting performance of an operation, where the call request includes a delay parameter specified by the call requester. The call handling system performs the requested operation, and sends a callback to the call requester, which includes partial results from performance of the requested operation, at selected intervals determined by the delay parameter.
1. A method comprising:
performing, by a first device, a requested operation for a period of time associated with a first value of a delay parameter,
the delay parameter being specified by a second device;
determining, by the first device, whether the first value has expired;
sending, by the first device and to the second device when the first value has expired, a response that includes partial results from performance of the requested operation;
updating, by the first device, a second value based on the partial results;
determining, by the first device and using the updated second value, whether the partial results complete the requested operation; and
determining, by the first device and based on determining that the partial results complete the requested operation, that the requested operation is complete.
2. The method of claim 1 , further comprising:
determining, by the first device and based on determining that the partial results do not complete the requested operation, if a second delay parameter is received.
3. The method of claim 2 , further comprising:
storing, based on determining that the second delay parameter is received, information regarding the second delay parameter; and
performing the requested operation for a period of time associated with a value of the second delay parameter.
4. The method of claim 2 , further comprising:
terminating, based on determining that the second delay parameter is not received, the requested operation.
5. The method of claim 1 , further comprising:
receiving a request to perform the requested operation; and
storing, based on receiving the request, context information associated with the request,
the context information including at least one of:
the first value of the delay parameter,
a session identifier associated with the request,
a counter value indicating a number of units associated with the request, or
a call back routine identifier.
6. The method of claim 5 , where the second value is the counter value.
7. The method of claim 5 , where the requested operation is complete when a number of units associated with a result of the requested operation is equal to the counter value.
8. A device comprising:
a processor to:
perform a requested operation for a period of time associated with a first value of a delay parameter,
the delay parameter being specified by a second device;
determine whether the first value has expired;
send, to another second device when the first value has expired, a response that includes partial results from performance of the requested operation;
update a second value based on the partial results;
determine, using the updated second value, whether the partial results complete the requested operation; and
determine, based on determining that the partial results complete the requested operation, that the requested operation is complete.
9. The device of claim 8 , where the processor is further to:
determine, based on determining that the partial results do not complete the requested operation, if a second delay parameter is received.
10. The device of claim 9 , where the processor is further to:
store, based on determining that the second delay parameter is received, information regarding the second delay parameter; and
perform the requested operation for a period of time associated with a value of the second delay parameter.
11. The device of claim 9 , where the processor is further to:
terminate, based on determining that the second delay parameter is not received, the requested operation.
12. The device of claim 8 , where the processor is further to:
receive a request to perform the requested operation; and
store, based on receiving the request, context information associated with the request, the context information including at least one of:
the first value of the delay parameter,
a session identifier associated with the request,
a counter value indicating a number of units associated with the request, or
a call back routine identifier.
13. The device of claim 12 , where the second value is the counter value.
14. The device of claim 12 , where the requested operation is complete when a number of units associated with a result of the requested operation is equal to the counter value.
15. A non-transitory computer-readable medium storing instructions, the instructions comprising:
one or more instructions which, when executed by at least one processor, cause the at least one processor to:
perform a requested operation for a period of time associated with a first value of a delay parameter,
the delay parameter being specified by a second device;
determine whether the first value has expired;
send, to another second device when the first value has expired, a response that includes partial results from performance of the requested operation;
update a second value based on the partial results;
determine, using the updated second value, whether the partial results complete the requested operation; and
determine, based on determining that the partial results complete the requested operation, that the requested operation is complete.
16. The non-transitory computer-readable medium of claim 15 , further comprising:
one or more instructions to determine, based on determining that the partial results do not complete the requested operation, if a second delay parameter is received.
17. The non-transitory computer-readable medium of claim 16 , further comprising:
one or more instructions to store, based on determining that the second delay parameter is received, information regarding the second delay parameter; and
one or more instructions to perform the requested operation for a period of time associated with a value of the second delay parameter.
18. The non-transitory computer-readable medium of claim 16 , further comprising:
one or more instructions to terminate, based on determining that the second delay parameter is not received, the requested operation.
19. The non-transitory computer-readable medium of claim 15 , further comprising:
one or more instructions to receive a request to perform the requested operation; and
one or more instructions to store, based on receiving the request, context information associated with the request,
the context information including at least one of:
the first value of the delay parameter,
a session identifier associated with the request,
a counter value indicating a number of units associated with the request, or
a call back routine identifier.
20. The non-transitory computer-readable medium of claim 19 , where the requested operation is complete when a number of units associated with a result of the requested operation is equal to the counter value.
