Abstract

A provisioning engine for provisioning communications services and a pattern language for configuring the provisioning engine. A plurality of objects can be assembled to define provisioning models representing state machines for carrying out common provisioning operations. The state machines include a set of plural current states of the provisioning model, mechanisms for generating signals, tasks, and at least one transition operative to define conditions under which the tasks are executed and states are added to or removed from the set of current states. Signals can be executed instantaneously or scheduled for later execution to permit provisioning operations to be controlled in a temporal manner. The provisioning models can be executed as specific instances and instances can include calls to other models to be executed as subinstances.

Claims

1. A method for provisioning communication services, the method comprising:

defining a state machine associated with a communication services provisioning model, the state machine comprising a set of current states of the provisioning model;

defining at least one transition within the provisioning model that defines conditions under which states are added to or removed from the set of current states of the provisioning model;

generating a signal that identifies when a transition occurs that either adds states to the state machine or removes states from the state machine; and

modifying arguments of the signal, by the at least one transition.

2. The method of claim 1, wherein the signal is generated by an external API of a provisioning engine.

3. The method of claim 1, wherein the signal is generated by one of the at least one transition.

4. The method of claim 1, wherein generating a signal that identifies when a transition occurs that either adds states to the state machine or removes states from the state machine further comprises:

generating a signal API call; and

delivering the signal at a predetermined time after generating the corresponding signal API call.

5. The method of claim 1, wherein the at least one transition comprises at least one of a signal type, a set of from states or a set of to states.

6. The method of claim 5, wherein the at least one transition performs at least one of adding the to states of the set of current states or removing the from states from the set of current states when a signal matching the signal type is received.

7. The method of claim 6, wherein the signal matching the signal type is received by an executing instance of the provisioning model and the from states are a subset of the set of current states.

8. The method of claim 1, wherein the provisioning model comprises a plurality of executing instances each storing data specific to a respective one of the instances.

9. The method of claim 8, wherein the provisioning model further comprises stored data to be used by each of the instances.

10. The method of claim 5, wherein the at least one transition further comprises at least one task that is executed when a signal matching the signal type is received.

11. The method of claim 5, wherein the from states are a subset of the set of current states.

12. The method of claim 10, wherein the at least one transition further comprises transition arguments that are communicated to the at least one task.

13. The method of claim 8, wherein at least one of the executing instances further comprises calls to another model as a sub-instance.

14. The method of claim 13, wherein the sub-instance further comprises means for communicating with the at least one instance.

15. The method of claim 13, wherein transitions of the at least one instance are configured to stop executing while the sub-instance executes and continues executing when the sub-instance is done executing.

16. A system for provisioning communication services, the system comprising:

means for defining a state machine associated with a communication services provisioning model, the state machine comprising a set of current states of the provisioning model;

means for defining at least one transition within the provisioning model that defines conditions under which states are added to or removed from the set of current states of the provisioning model; and

means for generating a signal that identifies when a transition occurs that either adds states to the state machine or removes states from the state machine, wherein the at least one transition modifies arguments of a generated signal.

17. The system of claim 16, wherein the at least one transition comprises at least one of a signal type, a set of from states or a set of to states.

18. The system of claim 17, wherein the at least one transition performs at least one of adding the to states to the set of current states or removing the from states from the set of current states when a signal matching the signal type is received.

19. The system of claim 17, wherein the signal matching the signal type is received by an executing instance of the provisioning model and the from states are a subset of the set of current states.

20. The system of claim 16, wherein the signal is generated by an external API of the system for provisioning communication services.

21. The system of claim 16, wherein the means for generating a signal further comprises:

means for generating a signal API call; and

means for delivering a signal at a predetermined time after a corresponding signal API call.

22. The system of claim 16, wherein the provisioning model comprises a plurality of executing instances each storing data specific to a respective one of the instances.

23. The system of claim 22, wherein the provisioning model further comprises stored data to be used by each of the instances.

24. The system of claim 17, wherein the at least one transition further comprises at least one task that is executed when a signal matching the signal type is received.

25. The system of claim 17, wherein the from states are a subset of the set of current states.

26. The system of claim 24, wherein the at least one transition further comprises transition arguments that are communicated to the at least one task.

27. The system of claim 22, wherein at least one of the executing instances further comprises calls to another model as a sub-instance.

28. The system of claim 27, wherein the sub-instance further comprises means for communicating with the at least one of the executing instances.

29. The system of claim 27, wherein transitions of the at least one instance are configured to stop executing while the sub-instance executes and to continue executing when the sub-instance is done executing.
