Abstract
Abstract The integrity of AMA records generated by a switch in the telephone network is achieved by generating test calls and then monitoring and then processing the AMA records generated by those switches in the network which handled the test call. Such monitoring includes tracking for the AMA records that have been generated for the test calls and then processing those records such that the contents of the fields forming the records are analyzed to determine that the data contained therein is correct.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
196 words
A method for verifying proper recording of information in a telephone network, comprising: initiating a feature on said telephone network; generating a plurality of test telephone calls, at least one of said telephone calls comprising said feature; maintaining a set of first records of said test telephone calls, each of said first records comprising a plurality of fields at least one of said fields corresponding to said feature, each of said first records corresponding to one of said test telephone calls; transmitting said test telephone calls through at least one switch; recording a set of second records of said test telephone calls having passed through said at least one switch, each of said second records comprising a plurality of fields, at least one of said fields corresponding to said feature, each of said second records corresponding to one of said test telephone calls; comparing the fields of said first records corresponding to each of said test telephone calls with the fields of said second records corresponding to said telephone calls to determine accuracy of said second records; and utilizing a central server to control the method through a single user interface on a live telephone network.
Claim 2
Independent Claim
196 words
A method for verifying proper recording of information in a telephone network, comprising: initiating a feature on said telephone network; generating a plurality of test telephone calls, at least one of said telephone calls comprising said feature; maintaining a set of first records of said test telephone calls, each of said first records comprising a plurality of fields at least one of said fields corresponding to said feature, each of said first records corresponding to one of said test telephone calls; transmitting said test telephone calls through at least one switch; recording a set of second records of said test telephone calls having passed through said at least one switch, each of said second records comprising a plurality of fields, at least one of said fields corresponding to said feature, each of said second records corresponding to one of said test telephone calls; comparing the fields of said first records corresponding to each of said test telephone calls with the fields of said second records corresponding to said telephone calls to determine accuracy of said second records; and utilizing a central server to control the method through a single user interface on a live telephone network.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein said comparing step comprises the step of determining and effects of said feature on the set of second records.
Claim 4
Dependent Claim
18 words
The method of claim 1 wherein said first records and said second records comprise automated message accounting records.
Claim 5
Dependent Claim
28 words
The method of claim 1 further comprising: performing a regression analysis on said telephone network to determine any effects of said feature on the set of second records.
Claim 6
Dependent Claim
50 words
The method of claim 4 wherein said regression analysis comprises comparing a record of a first test telephone call which does not implement said feature with a record of a second test telephone call which implements said feature to determine the effect of said feature on said live telephone network.
Claim 7
Dependent Claim
15 words
The method of claim 1 wherein said comparing comprises both template checking and specification checking.
Claim 8
Dependent Claim
33 words
The method of claim 6 wherein said comparing involves the use of testing tools which are automatically updated upon changes to specifications of said records or changes in said at least one switch.
Claim 9
Dependent Claim
37 words
The method of claim 4 wherein said comparing step is implemented between said first and second test telephone calls having similar fixed, provisioned and variable information, other than information pertaining to said implementation of said new feature.
Claim 10
Dependent Claim
14 words
The method of claim 1 wherein said feature is directed to call interaction information.
Claim 11
Dependent Claim
83 words
A recording verification method, comprising: generating a plurality of test calls, including at least one new feature in at least one test call; generating records of said test calls through at least one switch in a network; tapping into records generated by said at least one switch to extract copies of said records; and performing a regression analysis of said copies of said records by comparing recorded and expected information at multiple levels to determine if data contained within said records is correct.
Claim 12
Dependent Claim
83 words
A recording verification method, comprising: generating a plurality of test calls, including at least one new feature in at least one test call; generating records of said test calls through at least one switch in a network; tapping into records generated by said at least one switch to extract copies of said records; and performing a regression analysis of said copies of said records by comparing recorded and expected information at multiple levels to determine if data contained within said records is correct.
Claim 13
Dependent Claim
35 words
The method of claim 10 wherein said regression analysis comprises: monitoring said records generated by said at least one switch on said network; and processing said records to determine if data contained therein is correct.
Claim 14
Dependent Claim
17 words
The method of claim 11 wherein said monitoring step comprises tracking records generated for said test calls.
Claim 15
Dependent Claim
24 words
The method of claim 12 wherein said processing includes analyzing all fields forming said records through regular expression checking, enumeration checking or range checking.
Claim 16
Dependent Claim
15 words
The method of claim 10 wherein said generating is performed on a live telephone network.
Claim 17
Dependent Claim
16 words
The method of claim 14 wherein said generating is performed on a telephone network under load.
Claim 18
Dependent Claim
26 words
The method of claim 10 wherein said test calls are real calls in progress, said real calls having been generated by customers on a telephone network.
Claim 19
Dependent Claim
14 words
The method of claim 11 wherein said levels include variable, provisioned, and fixed levels.
Claim 20
Dependent Claim
99 words
A recording verification architecture, comprising: a call generator; a record retriever in communication with said call generator, wherein a retrieved record corresponds to a generated call; a record analyzer in communication with said call generator and said record retriever, said record analyzer adapted to perform a regression analysis on calls generated by said call generator and records retrieved from said record analyzer by comparing recorded and expected information at multiple levels to determine if data contained within said records are correct, wherein said record retriever is adapted to tap into calls in progress to retrieve information for said record.
Claim 21
Dependent Claim
99 words
A recording verification architecture, comprising: a call generator; a record retriever in communication with said call generator, wherein a retrieved record corresponds to a generated call; a record analyzer in communication with said call generator and said record retriever, said record analyzer adapted to perform a regression analysis on calls generated by said call generator and records retrieved from said record analyzer by comparing recorded and expected information at multiple levels to determine if data contained within said records are correct, wherein said record retriever is adapted to tap into calls in progress to retrieve information for said record.
