Abstract

A system for providing services in a communications network includes a service processing function, a universal directory function, and a nodal resource manager. The service processing function receives service requests, formulates requests for interworking functions based upon service requests, and formulates resource requests based upon service requests and interworking functions. The universal directory function receives addresses from the service processing function and returns interworking functions based upon addresses. The nodal resource manager receives resource requests and allocates resources to the service processing function in response to resource requests. The nodal resource manager maintains a resource database that includes an entry corresponding to each network resource managed by the nodal resource manager.

Claims

1-23. -23. (canceled)

24. A method for providing communication services, the method comprising the steps of:

determining a criterion for a resource to satisfy a service request;

outputting a set of candidate resources based on the criterion; and

evaluating the set of candidate resources for a best candidate to satisfy the service request.

25. A method according to claim 24, further comprising the steps of:

allocating the best candidate resource; and

setting an attribute associated with the allocated resource to indicate unavailability of the resource.

26. A method according to claim 25, wherein the criterion includes a priority criterion, and the attribute includes a priority identifier.

27. A method according to claim 26, further comprising the steps of:

comparing the priority identifier associated with the best candidate resource with the priority criterion; and

de-allocating the best candidate resource based on the comparison.

28. A method according to claim 24, wherein the evaluating step is executed by one of a plurality of evaluation functions.

29. A method according to claim 24, further comprising the steps of:

prioritizing the service request; and

displacing the service request with another service request designated as being of higher priority.

30. A method according to claim 24, wherein the steps of determining, outputting, evaluating are performed by a node that is configurable by a resource manager that monitors the set of candidate resources.

31. A method according to claim 24, wherein the request specifies an evaluation function for use in the evaluation of the set of candidate resources.

32. A method according to claim 24, wherein the evaluating step is performed according to a sufficiency criterion for halting the evaluation after determining a candidate resource that can satisfy the service request.

33. A method according to claim 24, wherein the evaluating step is halted based on a predetermined duration.

34. A system for providing communication services, the system comprising:

a node configured to determine a criterion for a resource to satisfy a service request and to output a set of candidate resources based on the criterion, the node being further configured to evaluate the set of candidate resources for a best candidate to satisfy the service request; and

a manager configured to communicate with the node for configuring the node.

35. A system according to claim 34, wherein the node is further configured to allocate the best candidate resource, and to set an attribute associated with the allocated resource to indicate unavailability the resource.

36. A system according to claim 35, wherein the criterion includes a priority criterion, and the attribute includes a priority identifier.

37. A system according to claim 36, wherein the node is further configured to compare the priority identifier associated with the best candidate resource with the priority criterion, and to de-allocate the best candidate resource based on the comparison.

38. A system according to claim 34, wherein the node evaluates based on one of a plurality of evaluation functions.

39. A system according to claim 34, wherein the node is further configured to prioritize the service request, and to displace the service request with another service request designated as being of higher priority.

40. An apparatus for providing communication services, the apparatus comprising:

means for determining a criterion for a resource to satisfy a service request;

means for outputting a set of candidate resources based on the criterion; and

means for evaluating the set of candidate resources for a best candidate to satisfy the service request.

41. An apparatus according to claim 40, further comprising:

means for allocating the best candidate resource; and

means for setting an attribute associated with the allocated resource to indicate unavailability the resource.

42. An apparatus according to claim 41, wherein the criterion includes a priority criterion, and the attribute includes a priority identifier.

43. An apparatus according to claim 42, further comprising:

means for comparing the priority identifier associated with the best candidate resource with the priority criterion; and

means for de-allocating the best candidate resource based on the comparison.

44. An apparatus according to claim 40, wherein the evaluation is executed by one of a plurality of evaluation functions.

45. An apparatus according to claim 40, further comprising:

means for prioritizing the service request; and

means for displacing the service request with another service request designated as being of higher priority.

46. An apparatus according to claim 40, wherein a node comprises the determining means, the outputting means, and the evaluating means, the node being configurable by a resource manager that monitors the set of candidate resources.
