Abstract
Abstract Increased reliability for intelligent call processing systems is provided by collecting information from communications between the network database, the subscriber database, and the network switch. Message transfers between these network elements are monitored and correlated to identify those messages corresponding to a particular call. The messages for the call are analyzed to determine which database generated the instructions for routing the call. In particular, by comparing the routing number returned to the interexchange switch with the routing instruction information supplied by the subscriber's database, it can be determined whether the call was routed according to instructions from the subscriber's database.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
94 words
A method for use in a telecommunications system which routes special service calls according to routing instructions obtained from a subscriber database, the method comprising the steps of: determining the routing instructions output by the subscriber database for a special service call; comparing the routing instructions output by the subscriber database with the routing instructions actually used to route the special service call; and responding to the result of the comparing step to provide an indication of whether the special service call was routed according to the routing instructions output by the subscriber database.
Claim 2
Independent Claim
94 words
A method for use in a telecommunications system which routes special service calls according to routing instructions obtained from a subscriber database, the method comprising the steps of: determining the routing instructions output by the subscriber database for a special service call; comparing the routing instructions output by the subscriber database with the routing instructions actually used to route the special service call; and responding to the result of the comparing step to provide an indication of whether the special service call was routed according to the routing instructions output by the subscriber database.
Claim 3
Dependent Claim
36 words
The invention of claim 1 wherein the comparing step comprises comparing a routing label output by the subscriber database for routing the special service call with the routing number used to route the special service call.
Claim 4
Dependent Claim
25 words
The invention of claim 1 wherein the responding step comprises generating an indication that the special service call was routed using a default routing instruction.
Claim 5
Dependent Claim
32 words
The invention of claim 1 further comprising the step of providing an indication of why the special service call was not routed according to the routing instructions output by the subscriber database.
Claim 6
Dependent Claim
42 words
The invention of claim 1 further comprising the step of determining the elapsed time between initiation of a query for routing instructions of the subscriber database by a network processor and receipt by the network processor of a response to the query.
Claim 7
Independent Claim
74 words
A method for use in an intelligent call processing system, the method comprising the steps of: monitoring message transfers between a network special service call database, a subscriber database, and a network switch; correlating messages corresponding to a predetermined special service call; and analyzing selected information derived from the messages of the predetermined special service call to determine whether the special service call was routed according to routing instructions specified by the subscriber database.
Claim 8
Independent Claim
74 words
A method for use in an intelligent call processing system, the method comprising the steps of: monitoring message transfers between a network special service call database, a subscriber database, and a network switch; correlating messages corresponding to a predetermined special service call; and analyzing selected information derived from the messages of the predetermined special service call to determine whether the special service call was routed according to routing instructions specified by the subscriber database.
Claim 9
Dependent Claim
30 words
The invention of claim 6 wherein the correlating step comprises identifying messages corresponding to the special service call on the basis of an identifier unique to the special service call.
Claim 10
Dependent Claim
30 words
The invention of claim 6 wherein the selected information includes a routing label specified by the subscriber database and a routing number specified by the network special service call database.
Claim 11
Dependent Claim
22 words
The method of claim 6 wherein the selected information comprises billing record information which indicates how the special service call was routed.
Claim 12
Dependent Claim
30 words
The invention of claim 6 further comprising the step of generating an indication of whether the special service call was routed according to routing instructions specified by the subscriber database.
Claim 13
Dependent Claim
25 words
The invention of claim 10 wherein the generating step comprises generating an indication that the special service call was routed using a default routing instruction.
Claim 14
Dependent Claim
32 words
The invention of claim 10 further comprising the step of providing an indication of why the special service call was not routed according to the routing instructions output by the subscriber database.
Claim 15
Dependent Claim
20 words
The invention of claim 6 further comprising the step of correlating the results of the analyzing step with non-routing information.
Claim 16
Dependent Claim
31 words
The invention of claim 13 wherein the correlating step comprises determining on a caller-by-caller basis whether the special service call was routed according to routing instructions specified by the subscriber database.
Claim 17
Independent Claim
76 words
A method for use in an intelligent call processing system, the method comprising the steps of: monitoring messages received by a network special service call database from a network switch and from a subscriber database; correlating messages corresponding to a predetermined special service call; and analyzing selected information derived from the messages of the predetermined special service call to determine whether the special service call was routed according to routing instructions specified by the subscriber database.
Claim 18
Independent Claim
76 words
A method for use in an intelligent call processing system, the method comprising the steps of: monitoring messages received by a network special service call database from a network switch and from a subscriber database; correlating messages corresponding to a predetermined special service call; and analyzing selected information derived from the messages of the predetermined special service call to determine whether the special service call was routed according to routing instructions specified by the subscriber database.
Claim 19
Dependent Claim
30 words
The invention of claim 15 wherein the correlating step comprises identifying messages corresponding to the special service call on the basis of an identifier unique to the special service call.
Claim 20
Dependent Claim
30 words
The invention of claim 15 wherein the selected information includes a routing label specified by the subscriber database and a routing number specified by the network special service call database.
Claim 21
Dependent Claim
22 words
