Abstract

To provide a complete picture of the calling pattern of calls placed to a destination entity which permits the destination entity'"'"'s routing plan to be adequately administered, a) information is collected about all call attempts to particular, specified dialed numbers even before they are switch routed, including even calls terminated before a network control point (NCP) returns instructions as to where to route the call and, if applicable, after they are rerouted and b) the collected information is periodically delivering as it becomes available, for use by the destination entity, without requiring the calls being monitored to have been terminated. Thus, for example, information is collected about calls being held by the NCP in a queue even before the calls are NCP routed. The collected information also includes information for calls that were never routed, because they were terminated before routing, independent of whether they were placed in a queue. If applicable, additional information is collected about the rerouting of those calls that are rerouted. Additionally, information is collected concerning the performance of a network control point, including information on queue performance and routing location selection performance.

Claims

1. A method for use in monitoring call attempts processed by the network of an interexchange carrier in which the switches of said network route said call attempts in response to received instructions, the method characterized by the steps of:

collecting, at a call data processor of said interexchange carrier, information relating to call attempts placed to at least one destination entity, said collecting being performed for each respective one of said call attempts prior to any routing of it by any of said switches; and

periodically supplying to said destination entity information relating to call attempts placed to said at least one destination entity as it is collected without waiting for the termination of said call attempts, said supplying being independent of said call attempts for which said information is collected in said collecting step and said supplied information including at least a portion of said information collected in said collecting step.

2. The invention as defined in claim 1 wherein said information collected in said collecting step includes information about call attempts for which none of said switches of said network of said interexchange carrier was ever able to route to a location of said destination entity prior to their termination.

3. The invention as defined in claim 1 wherein the information supplied in said supplying step pertains to at least one call attempt that has not terminated.

4. The invention as defined in claim 1 wherein said information collected in said collecting step includes information about a particular call attempt that is held in a queue in said network of said interexchange carrier prior to having any routing performed for it.

5. The invention as defined in claim 1 further including the step of:

collecting information relating to calls placed to said destination entity that were rerouted to at least one alternate location of said destination entity because said network of said interexchange carrier was unable to complete them to a first location to which they were initially routed and wherein said information supplied in said step of supplying also includes at least a portion of said information collected about said rerouted calls.

6. The invention as defined in claim 5 further including the step of:

collecting information relating to calls placed to said destination entity that were completed to a first location of said destination entity to which they were routed and wherein said information supplied in said step of supplying also includes at least a portion of said information collected about said calls completed to the first location which they were routed.

7. The invention as defined in claim 6 further including the step of:

arranging information collected in each of said collecting steps into a predetermined format and it is said arranged information that is supplied in said step of supplying.

8. The invention as defined in claim 7 wherein said destination entity specifies at least a portion of the characteristics of said predetermined format.

9. The invention as defined in claim 8 wherein said information supplied is selected according to predetermined criteria specified at least in part by said destination entity.

10. A method for use in monitoring calls placed over a network of an interexchange carrier to destination entities, at least one of said destination entities having more than one location at which it can receive calls, the method being of the type in which information is collected about said calls and portions of said information relating to calls destined for particular destination entities are made available to those destination entities in a specified format, the improvement characterized by:

collecting information for those calls terminated before the performance of any network control point routing by said network of said interexchange carrier; and

receiving from each respective one of said destination entities a specification of the format for making its portion of said information available.

11. The invention as defined in claim 10 wherein each format specification specifies the types of information that is made available to the destination entity from which said specification is received.

12. The invention as defined in claim 10 wherein said format specification specifies the appearance, as displayed, of the information that is made available to the destination entity from which said specification is received.

13. The invention as defined in claim 10 wherein said information collected about said calls further includes information for calls that were held in a queue by said interexchange carrier prior to having any routing performed by said interexchange carrier.

14. The invention as defined in claim 10 wherein said information collected about said calls further includes information about calls that were rerouted to at least one alternate location of said destination entity because said network of said interexchange carrier was unable to complete them to a first location to which they were initially routed.

15. A method for use in monitoring telephone calls placed to a destination entity via a network, the method comprising the steps of:

collecting information particularly relating to the queuing of a call in an network control point (NCP) of said network, said call having been (i) placed to said destination entity and (ii) having been held in a queue in said NCP prior to having any routing performed for said call; and

supplying to said destination entity at least a portion of said information collected about said queued call.

16. A method for use in monitoring telephone calls placed to destination entity via a network of an interexchange carrier, the method comprising the steps of:

collecting information relating to a call placed to said destination entity, said call having been held in a queue in an network control point of said network, said collecting being prior to having any routing performed for said call; and

supplying to said destination entity at least a portion of said information collected about said queued call.

17. A method for use by a call data processor to monitor telephone calls placed by callers to destination entities over a telephone network, said telephone network having an associated network control point, said network control point communicating with switches of said telephone network via the exchange of signaling messages of a predefined message set over a signaling network, the method comprising the steps of:

receiving information from said network control point about the treatment given to telephone calls placed over said telephone network to said destination entities, said information being undeterminable solely from any signaling messages suppliable to or from said network control point, or any combination thereof, without the use of data available only in said network control point; and

supplying to said destination entities at least a portion of said information received from said network control point.

18. The invention as defined in claim 17 wherein said received information includes information about calls that are held in a queue prior to having any routing performed.

19. The invention as defined in claim 17 wherein said received information includes information relating to calls for which said network control point considered and rejected at least one location of said destination entity because it believed that an attempt to route a call to such a location would fail.

20. The invention as defined in claim 17 wherein said received information includes information relating to the alternate handling of calls placed to said destination entities because queues in said network control point, each associated with of said destination entities and into which said calls to their associated destination entities were to be temporarily placed, were full at a time when said calls were to be placed therein.

21. The invention as defined in claim 18 wherein said received information includes information relating to calls that said network control point predicted could be completed to a particular location of said destination entity but said telephone network was unable to so complete said calls.

22. The invention as defined in claim 19 wherein said received information includes information relating to calls that said network control point predicted could be completed to a particular location of said destination entity but said telephone network was unable to so complete said calls.

23.
