Abstract

Embodiments of the invention provide systems and methods for providing low-latency handling of events and/or requesting actions of external resources in a real time environment while utilizing non-real time components. According to one embodiment, a system for providing low-latency handling of events in a real time environment while utilizing non-real time components can comprise an external resource and a resource adapter communicatively coupled with the external resource. The resource adapter can be adapted to detect events of the external resource and/or request actions of the external resource. The system can also include at least one local application communicatively coupled with the resource adapter. The local application can have a local interface and the local application can interact with the resource adapter via the local interface.

Claims

1. A system for providing low-latency handling of events in a real time environment while utilizing non-real time components, the system comprising:

an external resource;

at least one resource adapter communicatively coupled with the external resource, the resource adapter adapted to interact with the external resource; and

at least one local applications communicatively coupled with the resource adapter, the local application having at least one local interface, wherein the local application interacts with the resource adapter via the local interface to interact with the external resource.

2. The system of claim 1, wherein the resource adapter is adapted to detect events of the external resource and request actions of the external resource.

3. The system of claim 2, wherein the external resource comprises a communication network.

4. The system of claim 2, wherein the external resource comprises an Operation Support System (OSS).

5. The system of claim 2, wherein the external resource comprises an Business Support System (BSS).

6. The system of claim 3, wherein the communication network further comprises one or more network resources.

7. The system of claim 2, wherein the local applications is adapted to receive an indication of the event from the resource adapter via the local interface.

8. The system of claim 7, wherein the local application is further adapted to react to the event.

9. The system of claim 8, wherein the local application is adapted to react to the event by requesting an action of the external resource via the local interface and the resource adapter.

10. The system of claim 2, wherein the local application is adapted to request an action of the external via the local interface and the resource adapter.

11. The system of claim 3, wherein the local application is adapted to perform call control.

12. The system of claim 3, wherein the local application is adapted to perform multi-party call control.

13. The system of claim 3, wherein the local application is adapted to perform media control.

14. The system of claim 3, wherein the local application is adapted to provide a web service.

15. The system of claim 6, wherein the network resources comprise a Parlay Gateway.

16. The system of claim 15, wherein the resource adapter comprises a Parlay Java Rulebook Connector Architecture (JCA) 1.5 resource adapter.

17. The system of claim 6, wherein the resource adapter comprises a Signaling System 7 (SS7) resource adapter.

18. The system of claim 6, wherein the resource adapter comprises a Customized Applications for Mobile Network Enhanced Logic (CAMEL) resource adapter.

19. The system of claim 6, wherein the resource adapter comprises an Intelligent Network Application Part (INAP) resource adapter.

20. The system of claim 6, wherein the resource adapter comprises a, Transaction Capabilities Application Part (TCAP) resource adapter.

21. The system of claim 16, wherein the local interface comprises a Parlay Java Rulebook Application Program Interface (API) library.

22. The system of claim 16, wherein the local interface comprises a Plain Old Java Bean (POJO).

23. The system of claim 16, wherein the local interface comprises an Enterprise Java Bean (EJB).

24. The system of claim 1, further comprising:

a remote interface communicatively coupled with the local application; and

a remote application communicatively coupled with the remote interface, wherein the remote application is adapted to interact with the local application via the remote interface.

25. The system of claim 1, wherein the local interface passes data by reference.

26. The system of claim 1, wherein the at least one resource adapters comprise a first resource adapter and a second resource adapter.

27. The system of claim 26, wherein the first resource adapter and second resource adapter manage respective thread pools separately.

28. The system of claim 26, wherein the at least one local interface comprises a first local interface for interacting with the first resource adapter and a second local interface for interacting with the second resource adapter and wherein the local application is adapted to interact with the first resource adapter via the first local interface and the second resource adapter via the second local interface.

29. The system of claim 28, wherein the first resource adapter, second resource adapter, first local interface, and second local interface are adapted to prevent introspection.

30. The method of claim 1, wherein the at least one resource adapter and the at least one local interface are implemented on a Java Virtual Machine (JVM).

31. The system of claim 30, wherein the JVM is tuned to reduce pauses caused by a garbage collection process.

32. The system of claim 30, wherein the JVM utilizes a concurrent mark and sweep garbage collection process.

33. A method for providing low-latency handling of events in a real time environment while utilizing non-real time components, the method comprising:

detecting an external event with a resource adapter;

sending an indication of the external event from the resource adapter to a local application via a local interface of the local application; and

handling the external event with the local application.

34. The method of claim 33, wherein handling the external event with the local application comprises requesting an action of an external resource via the local interface and the resource adapter.

35. The method of claim 34, wherein the external event comprises a network event.

36. The method of claim 35, wherein handling the external event with the local application comprises performing call control.

37. The method of claim 35, wherein handling the network event with the local application comprises performing multi-party call control.

38. The method of claim 35, wherein handling the network event with the local application comprises performing media control.

39. The method of claim 35, wherein handling the network event with the local application comprises providing a web service.

40. A method for requesting actions of resources in a real time environment while utilizing non-real time components, the method comprising:

sending a request for an action of an external resource from a local application via a local interface of the local application;

receiving the request for the action of the resource at a resource adapter via the local interface of the local application; and

requesting the action of the network resource from the resource adapter.

41. The method of claim 40, wherein the external resource comprises a communication network.
