  • Patent number: 7133500
    Abstract: Method and apparatus for conducting surveillance in a SS7 Intelligent Network (IN) or Advanced Intelligent Network (AIN) provides in the case of AIN that an Info Analyzed trigger is armed in an end office switch and notifies a delivery function when a call is processed. The delivery function instructs the end office switch to forward the call to the delivery function, where it is accessed for monitoring forwarded back to the end office switch. A similar method is used to process calls received by the SUS. In the case of IN, the identity of a line card assigned to a subscriber under surveillance (SUS) is changed to a number dedicated to surveillance subjects. Calls originated by the SUS are forwarded to a delivery function, which identifies the SUS based on the dedicated number of the calling party, intercepts call content, and forwards the call back to the end office switch with the called party id aid the original number and id of the SUS. The end office switch then completes the call.

  • Patent number: 6665386
    Abstract: A system and method downloads data and reconfigures the data into a database. A telephone user purchases a specific number of lines and specific services (i.e., call waiting) from a telephone company. The telephony company then programs a switch associated with that user so that the user receives the services purchased. The telephone company also inserts the user's purchases into a database used for generating the user's bills. Discrepancies can occur between the data in the switch and the data in the billing database. Billing correction is performed by downloading all of the data within a switch, reconfiguring the data into a database and then comparing the switch database against the billing database to detect billing errors. To facilitate ease of this billing correction process, the switch database is transmitted to the billing correction center via a network instead of the traditional method of using direct tape copies of the switch being physically transported to the billing correction center.

  • Patent number: 6385301
    Abstract: A monitoring system captures and processes messages from SS7 links, to compile call detail records (CDRs) for all interoffice call attempts. The CDRs are uploaded into a relational database. Automatic Message Accounting (AMA) records also are accumulated and uploaded to another relational database. A data preparation operation enhances the records for further processing. This data preparation operation involves translating information in the records into more useful forms, using external reference data regarding the monitored network. For example, the data preparation translates SS7 point codes or NPA-NXX codes in the records to textual names of originating and terminating offices. The data preparation also spreads the usage information from the records to properly allocate usage time to predefined intervals. Another function of the data preparation stage is to form one or more predefined tables from the processed records, for example a table of modified records and one or more specialized summary tables.

  • Patent number: 6373932
    Abstract: A configuration tracking system for a call detail record (CDR) filtering system keeps track of the contexts under which CDRs are collected and filtered. The configuration tracking system is useful in a multiple concurrent filtering paradigm, in which several CDR filters may be active at any given time and the filter criteria are dynamically altered. Filter criteria for multiple filters are recorded in a dynamically changing table. The configuration tracking system maintains a historical record of the filter criteria in the dynamically changing table. The configuration tracking system updates its historical record by detecting changes in the dynamically changing filter table, comparing earlier and later versions of the table, and opening and/or closing timestamped filter records in response.

  • Patent number: 6212266
    Abstract: A method and system for detecting fraud in a telecommunications network matches information on individual calls to a series of rules (18). For each rule r, a threshold Tr is defined, and if the fit of an individual call to that rule is exceeds Tr, an alarm is generated. All call records resulting in alarms are stored within a positive matching file. Likewise, calls which just fail to meet the criteria, within a given tolerance level &THgr;, are stored in a separate negative matching file. The entries in the positive and negative matching files are then checked by skilled operators to determine which in fact represent true fraud. On the basis of those validations, a decision module within the system automatically calculates and implements the necessary changes to the thresholds Tr by means of a feedback loop.
