BACKGROUND TO THE INVENTION
An increasing number of vendors are offering goods and/or services which may be purchased via a communication network such as a telecommunication network. For example, the customer may conduct a transaction via a subscriber line using a landline telephone or a personal computer. Conventionally, credit or debit card details are furnished by the customer to the vendor to effect payment for the goods and/or services. As many customers are hesitant to supply credit or debit card details over a communication network, an alternate method of payment would be advantageous. However, if an alternate method is used, verification of the payment method should preferably take place prior to concluding the transaction.
SUMMARY OF THE INVENTION
In accordance with the invention, there is provided a method to provide validation data associated with a subscriber line of a telecommunication network, the method including:
obtaining line data of the subscriber line, the line data being suitable for interrogating a line identification database (LIDB);
interrogating the LIDB with the line data to obtain reference subscriber data associated with the line data; and
processing the reference subscriber data to obtain validation data associated with the subscriber line.
The LIDB may be a conventional LIDB used by a service provider, e.g. a local exchange carrier, to investigate a destination or termination line to which a carrier requests a connection.
The method may include analyzing the reference subscriber data to determine if the data is associated with a billing telephone number (BTN) and, if so, generating an approval or a decline status. In one exemplary embodiment, the line data is automatic number identification (ANI) data and, the method includes interrogating the LIDB using the ANI data (herein also referred to as the ANI). The validation data may be processed to determine whether the subscriber line is a billable line having an associated account to which goods or services can be billed.
The reference subscriber data received from the LIDB may be processed selectively to approve a transaction requested via the subscriber line. In one exemplary embodiment, the reference subscriber data is in the form of conventional LIDB codes and the operation to process the data may include generating a modified code from at least one LIDB code. In certain embodiments, a common modified code is generated from a plurality of LIDB codes. The modified codes may be arranged in a billable group and a non-billable group.
The method may include conducting fraud control checks on the account associated with the subscriber line number or ANI. The fraud control checks may include at least one of the operations selected from the group consisting of checking if adjustments have been made to the account associated with the ANI, verifying a user entered ZIP code with ZIP data from a ZIP data source, verifying user entered address data with address data from an address data source, checking if the area code associated with the ANI has changed, checking if the ANI and the BTN match, and checking if the BTN or ANI are missing from the record.
The method may include interrogating a network database with the ANI to determine if the subscriber line is a billable subscriber line and, if not, generating a decline status. The method may include interrogating with the line data at least one of a competitive local exchange carrier (CLEC) database, a 42 BLOCK database, a Block and Cancel database, an unpaid bills database, an off network database, an on network database, an address verification database, a regional account office (RAO) database, an operating company number (OCN) database, and a customer account record exchange (CARE) database and selectively generating one of a decline status and an approved status in response to the interrogation.
The method may include receiving the line data from a vendor of goods or services (e.g. an Internet Service Provider (ISP)); and communicating at least the decline status to the vendor.
In one exemplary embodiment, the charges raised by the vendor are included in an account submitted by the exchange carrier to a subscriber for use of the subscriber line.
Further in accordance with the invention, there is provided a computer-readable medium for storing a set of instructions that, when executed by a machine, cause the machine to execute the method.
Still further in accordance with the invention, there is provided a subscriber line validation system for validating a subscriber line of a communication network, the system including:
a communication module for receiving line data of the subscriber line, the line data being suitable for interrogating a line identification database (LIDB);
an interrogation module for interrogating the LIDB with the line data to obtain reference subscriber data associated with the line data; and
a processor module for processing the reference subscriber data to obtain validation data associated with the subscriber line.
In one exemplary embodiment, the LIDB is a conventional LIDB. However, in other embodiments, a plurality of LIDBs may be provided that are used by one or more service providers, e.g. local exchange carriers, to investigate a destination or termination line to which a subscriber line requests a connection.
In one exemplary embodiment, the processor module is configured to analyze the reference subscriber data to determine if the data is associated with a billing telephone number (BTN) and, if so, the system generates a decline status. In one embodiment, the line data is automatic number identification (ANI) data and the processor module interrogates the LIDB using the ANI data.
The validation data may be processed to determine if the subscriber line is a billable line having an associated account to which goods or services can be billed.
The reference subscriber data may be received from the LIDS and may be processed selectively to approve a transaction requested via the subscriber line.
The reference subscriber data is preferably in the form of conventional LIDB codes and the processor module may generate a modified code from at least one LIDB code. In certain embodiments, the processor module generates a common modified code from a plurality of different LIDS codes. In one embodiment, the modified codes arc arranged in a billable group and a non-billable group.
In certain embodiments, the system may conduct fraud control checks on an account associated with the ANI. The processor module may be configured to conduct at least one fraud control check selected from the group consisting of checking if adjustments have been made to the account associated with the ANI, verifying a user entered ZIP code with a ZIP data source, verifying user entered address data with an address data source, checking if the area code associated with the ANI has changed, checking if the ANI and the BTN match, and checking if the BTN or ANI are missing from the record.
The processor module may interrogate a network database with the ANI to determine if the subscriber line is a billable subscriber line and, if so, generate a decline status.
In certain embodiments, the system may interrogate at least one of a competitive local exchange carrier (CLEC) database, a 42 BLOCK database, a Block and Cancel database, an unpaid bills database, an off network database, an on network database, an address verification database, a regional account office (RAO) database, an operating company number (OCN) database, and a customer account record exchange (CARE) database.
The system may include receiving the line data from a vendor of goods or services; and communicating at least the decline status to the vendor. Charges raised by the vendor may be included in an account submitted by the exchange carrier to a subscriber for use of the subscriber line.
Further in accordance with the invention, there is provided a system to provide validation data associated with a subscriber line of a telecommunication network, the system including means for obtaining line data of the subscriber line, the line data being suitable for interrogating a line identification database (LIDB); means for interrogating the LIDB with the line data to obtain reference subscriber data associated with the line data; and means for processing the reference subscriber data to obtain validation data associated with the subscriber line.

DETAILED DESCRIPTION
Referring to the drawings, reference number 10 generally indicates an exemplary subscriber line validation system, in accordance with an aspect of the invention, for validating a subscriber line 17 of a subscriber. In one exemplary embodiment, the subscriber line 17 is a telephone line or the like which a consumer or business 11 (see FIGS. 1 and 5) obtains from a telephone company (Telco) 13 or a local exchange carrier (LEC). As described in more detail below, the system 10 uses line data in the exemplary form of an automatic number identification (ANI) service to obtain the telephone line number of the subscriber line 17 thereby to validate the subscriber line 17 when the subscriber line 17 initiates a communication or connection. In one exemplary embodiment, the line number obtained from the ANI service is used to investigate various databases to obtain, for example, an indication of the credit worthiness of the subscriber account associated with the subscriber line 17. It is to be appreciated that any electronic apparatus, e.g. a personal computer, PDA, cellular telephone, or the like may be used to initiate the communication.
Referring in particular to FIG. 1 of the drawings, the system 10 includes an application program interface (API) 14 which is connected to a vendor 12 or service provider (see also FIG. 5) of goods and/or services which requires validation of a subscriber account. The vendor 12, which could for example be an Internet Service Provider, may request the validation of the subscriber line 17 prior to concluding an electronic transaction with a subscriber (e.g., a consumer or business 11) via the subscriber line 17. It is, however, to be appreciated that the API 14 may be connected to a variety of different hosts or clients which require validation of a subscriber line via which the vendor may carry out transactions for goods and/or services.
In one exemplary embodiment, the system 10 is connected to a plurality of vendors which conduct transactions with users via line termination equipment such as a telephone, a personal computer or the like. Such vendors, when conducting transactions, may preferably charge a user for their services by adding such charges to a telephone account of the user rather than charging the goods and/or services to a credit card, debit card, or the like. Accordingly, the validation of the subscriber line 17, and the subscriber account associated with the subscriber line 17, may be of benefit to the vendor 12 prior to completing a transaction. The validation may include determining whether or not the subscriber line 17, via which the communication is made to the vendor, is a billable line and, accordingly, the subscriber account associated with the subscriber line 17 may thus be billed for the transaction.
In one exemplary embodiment, the vendor 12 communicates a request to the system 10 and forwards the subscriber line number, determined by the ANI service, to the system 10 via its API 14. The system 10 then processes the information received from the vendor 12 and provides a validation status, e.g. a code indicating a valid billable number or a code indicating that the subscriber line number is not a valid billable number (e.g. unbillable or non-billable). In particular, a plurality of codes associated with various statuses of the subscriber line 17 may be communicated to the vendor 12 as described in more detail below.
The system 10 includes hardware and software to implement the invention. In the exemplary embodiment, the system 10 includes a comparator module 18, a threshold database 20, an OFFNET database 22, an ONNET database 24, a competitive local exchange carrier (CLEC) database 26, a 42 BLOCK database 28, a block and cancel database 30, an unbilled and/or unpaid bills database 32, line identification database (LIDB) short term cache 34, a validity check module 36, a regional account office (RAO) database 38, an operating company number (OCN) database 40, an ONNET database 42, an address verification database 44, a customer account record exchange (CARE) results database 46, an ANI watch database 48, and an NPA (Numbering Plan Area) exchange database 50. It is to be appreciated that, in less sophisticated embodiments of the invention, all of the above databases need not be included. However, for enhanced accuracy, all of the above databases are preferably included. Further databases may also be included to further enhance the reliability of the validation process.
In addition to any one or more of the above databases, the system 10 is in communication via a conventional communication channel with an off-site or, in some embodiments, on-site line identification database (LIDB) host 52. The LIDB host 52 may include a line number portability (LNP) database. In one exemplary embodiment, the LNP database may front end access to a plurality of industry standard LIDBs (e.g. 13 different LIDBs). The LNP database may however be a separate database. As described in more detail below, the system 10 communicates the subscriber line number to the LIDB host 52 which, in turn, communicates reference subscriber data in the form of industry standard LIDB codes back to the system 10 for processing. The system 10 then processes the LIDB codes to provide the vendor with validation data relating to the subscriber line 17. Unlike conventional LIDB applications which use LIDB to make decisions regarding destination subscriber lines or call completion decisions, e.g. decisions for calling cards, collect and third party toll services or the like, the system 10 may be used to identify telephone numbers being served by CLECs in order to ensure that calls are routed correctly on ported lines.
Broadly, the system 10 has a variety of different components, including a communication module defined by the API 14, and a processor module 54. The a processor module 54 includes the various databases 20 to 32 as well as the comparator module 18 and the validity check module 36, and an interrogation module 56 for interrogating the LIDS host 52. It is to be appreciated that the aforementioned modules may be defined by one or more servers with associated databases. Further, in the drawings, the LIDB host 52 is shown as a single database but may comprise many different LIDB databases maintained by various LECs and, accordingly, may be located at various different geographic locations.
Referring in particular to FIGS. 2 to 4 of the drawings, a flow chart describing the method of operation of the system 10 is shown. In one exemplary embodiment, a vendor 12 initiates a request to the system 10 to validate a subscriber line 17 via which the vendor 12 wishes to transact with a customer (consumer or business 11). As shown at operation 60, the system 10 first checks to see if the subscriber line number is present in the request from the vendor 12 and, if no line number is present, a return code 121 is generated and communicated to the vendor as shown at operation 62. The code 121 indicates to the vendor that the system 10 is unable to process the request. If, however, the subscriber line number is present in the request from the vendor 12, the system 10 then checks if the subscriber line number captured (hereinafter also referred to as the ANI) and a billing telephone number (BTN) match, as shown at operation 64 (see also the comparator module 18 in FIG. 1). In one exemplary embodiment, the BTN may be sourced from the consumer or customer 11 when a transaction is requested by the customer 11. If, however, the ANI and the BTN do not match, then the processor module 54 generates a code 120 (see operation 66) to indicate that the caller and the owner of the line number are not the same person (e.g. subscriber inputs a BTN and calls from a different ANI) and the relevant modified code is then returned to the vendor 12. If the ANI and the BTN do match, the processor module 54 interrogates the threshold database 20 (see operation 68) to ascertain whether or not the line number has reached its threshold (e.g., a predefined client threshold parameter such as an account threshold indicating a maximum dollar amount that may be charged to the account). If the line number has reached its threshold, the processor module 54 then generates a code 60, as shown at operation 70, which is then communicated to the vendor 12 to indicate that the line number should not be granted service. In other words, the subscriber account cannot be billed for the goods or services requested by the customer 11 from the vendor 12.
If the threshold for the particular subscriber line 17 has not been reached, the system 10 may then interrogate its OFFNET database (see operation 71) to check if the industry standard NPA/NXX and operating company number (OCN) of the subscriber line 17 is present in the OFFNET database 22. The OFFNET database 22 includes NPA/NXX and OCN combinations of operating companies with which the proprietor or user of the system 10 does not have billing and collection agreements to bill into the telephone company's or Telco's bill page associated with the subscriber line 17. Accordingly, the proprietor or user of the system 10 is unable to include a charge in the account associated with the subscriber line 17 on behalf of the vendor 12 for the transaction carried out with the vendor 12 via the subscriber line 17.
If the line number is in the OFFNET database 22, then the processor module 54 generates codes 130 to 133 (see operation 72) and communicates these codes to the vendor 12. The codes 130 to 133 indicate that the NPA/NXX and OCN for the particular line number 17 are not billable and, accordingly, charges for goods and/or services requested by a customer 11 via the subscriber line 17 cannot be included in a monthly account or the like by the system 10. As shown in Table 2 below, the codes 130 to 133 provide an indication to the vendor 12 why the subscriber line 17 is not billable or deliverable. If the subscriber line number is not included in the OFFNET database 22, a check is conducted to see whether or not the subscriber line number is included in the ONNET database 24. This check is however optional in the embodiment depicted in the drawings, but in certain embodiments, may be mandatory if the system 10 does not include the OFFNET database 22.
Thereafter, as shown in operation 78, the processor module 54 checks to see if the line number 17 is found in a known CLEC table in the CLEC database 26. CLEC numbers are those line numbers that are known to have ported to a CLEC and, accordingly, the proprietor of the system 10 is thus unable to route these line numbers to the correct billing entities. If the line number is found in the CLEC database 26, then the processor module 54 generates a code 140 (see operation 76), which is communicated to the vendor 12. The code140 indicates that the line number is not billable for the CLEC and the system 10 can thus not charge the transaction to the subscriber account associated with the subscriber line 17.
If the line number is not found in the CLEC database 26, then the system 10 may check to see if the subscriber of the line number has requested a 4250 billing block as shown at operation 78. In particular, the processor module 54 interrogates the 42 BLOCK database 28 and, if the number is located in the database 28, which indicates that monthly recurring charges (4250 charges) are prevented from being billed to that line number, the processor module 54 generates a code 150 (see operation 80) which is communicated to the vendor 12 to indicate that billing to the particular subscriber line 17 has been blocked.
If, however, the subscriber line 17 has not been blocked, the system 10 may then check at operation 82 if the line number is located in the block and cancel database 30 and, if so, the processor module 54 generates codes 160 and 161 which are then communicated to the vendor 12 as shown at operation 84. The block and cancel database 30 includes requests from owners of subscriber lines, agencies, businesses, or the like that a service be canceled or blocked from further billing. Thereafter, the system 10 may interrogate the unbilled and/or unpaid bills database 32, as shown at operation 86, to check if there is a history of any unpaid bills and/or unbillable bills associated with the subscriber line 17. Unbillable bills relate to those subscriber line numbers where previous attempts have been made to bill charges to the subscriber account associated with the subscriber line number 17, and which have been returned as unbillable. If the processor module 54 locates the subscriber line number in the unbillable and/or unpaid bills database 32 then, as shown at operation 88, a code 170 is generated and communicated to the vendor 12 to indicate that the subscriber line number was previously found to be unbillable and is still considered to be unbillable.
The processing described in the abovementioned operations may conduct a preliminary investigation into the subscriber line number or ANI to provide an initial indication of whether or not the ANI corresponds with a billable subscriber line. Once the initial investigation has been conducted in certain embodiments, the system 10 then uses the ANI to obtain reference subscriber line data in the form of LIDB codes from one or more industry standard databases, e.g. the LIDB host or database 52. Examples of the LIDB codes used in the system 10 are shown in Table 3 below.
As shown at operation 90, if the ANI is not found in the LIDB database 52, then the system 10 cannot provide any validation data to the vendor 12 on this subscriber line and an appropriate code is then communicated to the vendor as shown at block 92.
Once the LIDS database or host 52 has been interrogated, it returns industry standard LIDB codes and line number portability (LNP) data to the system 10 as shown in operation 94. The LIDB codes may then be mapped or translated by the processor module 54 into modified validation codes (see Table 3 which provide relevant validation information to the vendor 12. As can be seen from Table 3, the same modified validation code can be generated from a plurality of different LIDB codes. Once the LIDB information codes have been returned to the processor module 54, the LIDB codes, including an OCN and RAO response codes, are fed into the validity check module 36 as shown at operation 96.
As mentioned above, the LIDB host 52 may also provide LNP data to the system 10. The LNP data is used to identify subscriber line numbers that have ported to a CLEC. If a subscriber line has been ported to a CLEC, the billing ONNET status of the CLEC may be verified in the CLEC database 26. The LNP identifies the facilities based CLECs which are CLECs that have been assigned all the line numbers for an NPA/NXX in a specific geographic territory. This type of CLEC may be in control of the cable, dial tone and billing envelope for that number. In one exemplary embodiment, the LNP cannot be used to identify CLEC sellers, which have resold the subscriber line under their brand, but still lease the cable and tone from an incumbent local exchange carrier (ILEC). Accordingly, a third-party billing facility, e.g. a proprietor or user of the system 10, may be unable to process transaction data onto a bill page of the CLEC reseller bill page. In order to identify reseller CLECs, the system 10 may compare RAO and OCN information, returned from the LIDB host 52, to data in the ONNET database 24. The OCN is the local Telco that owns the subscriber line number and the RAO is the office of the Telco that is responsible from a billing standpoint for the subscriber line number.
If the validity check module 36 determines that the response codes are invalid, the system 10 generates modified codes 180 to 999 (see operation 98 and Table 2) which are communicated to the requestor or vendor to indicate that the mapping of the LIDB codes to the modified codes concluded that the line is an unbillable subscriber line.
If the validity check module 36 confirms the validity of the LIDB codes and, in the event of the line number being a billable line number, the processor module 54 then may check the RAO database 38 to ascertain whether or not the RAO is billable, as shown at operation 100. If the RAO is not billable, then the processor module 54 generates and communicates a return code 143 (see operation 102) to indicate to the vendor 12 that the line number belongs to a CLEC which is not billable by the system 10.
In a similar fashion, at operation 104 the processor module 54 checks to see if the OCN returned from the LIDB host 52 corresponds with a known CLEC or if the OCN corresponds with an OFFNET OCN and is therefore also unbillable by the system 10. If the line number corresponds to an OCN that is not billable, a return code 142 is generated by the processor module 54 and communicated to the vendor (see operation 106).
If the subscriber line number has passed the RAO and OCN checks and, accordingly, it appears that the number is billable, the processor module 54 may then check to see if a new NPA/NXX and OCN combination for this line number is guidable to the correct local Telco for billing (see operation 108). If the line number is not guidable, then the system 10 generates a code 141 at operation 110 which is communicated to the vendor to indicate that, even though the line number is billable, the proprietor of the system 10 is unable to guide the billing information to the new Telco for billing. Accordingly, the telephone number is in fact non-billable insofar as the system 10 is concerned and a decline status is therefore communicated to the vendor 12.
The abovementioned operations are carried out to ascertain whether or not the subscriber line can be billed for the goods and/or services requested. However, to enhance the accuracy or reliability of the system 10, further checks or verification may be conducted as described below.
In the event that the subscriber line number has passed or complied with the abovementioned checks, and has thus not yet been rejected, the system 10 may perform address verification procedures at operation 112. In particular, when the ANI is communicated to the API 14, location data is also provided which has been fed in by the user, e.g. via a computer terminal, orally over a telephone, or the like. The system 10 then interrogates an address verification database 44 to compare the address or location data (e.g. a ZIP code) supplied by the customer 11 with a reference address data as shown at operation 112. If, however, the address supplied by the customer 11 does not match with the address in the verification database 44 or, the addresses are not within a predefined range or area, the processor module 54, as shown at operation 114, generates codes 10 to 39 which are then communicated to the vendor 12 to indicate the level of likelihood that the caller (ANI) and the account owner are the same person.
During the address verification operation 112, the system 10 may interrogate a customer account record exchange (CARE) database 46 (which can be an on-site database which is regularly updated), to provide enhanced reliability. In particular, in one exemplary embodiment, the CARE database 46 or information site is one or more industry standard off-site databases which allow consumers to select or change their long distance service provider. Local Telcos forward specific customer information to the LEC associated with the subscriber. In one exemplary embodiment, the information communicated includes a new telephone number, a billing address, an installation date, a person or organization responsible for the account, or the like.
As shown at operation 116, the system 10 may interrogate the CARE database or information site and CARE data is then loaded into CLEC and new line databases to perform certain fraud and/or billing checks. The CARE information investigation may occur after a successful validation event. In one embodiment, once the system 10 has validated the subscriber line 17, the subscriber line number data is sent to a CARE database provider hosting the CARE database 46 to obtain the BNA (Billing Name and Address) and age of the account. In one exemplary embodiment, the information is returned within 48 hours and then processed. CARE records that are returned without BNA and NO ACCOUNT codes may be inserted into the CLEC database 26 for future reference. Accordingly, if the BTN is presented again at a later date, it will fail the CLEC check operation 74 (see FIG. 2).
The ANI watch database 48, which may include historical and adjusted information, may be used by the system 10 to determine if the account has previously been adjusted (see operation 116). In one exemplary embodiment, this operation includes ascertaining previous requests by the subscriber for credit, obtaining data on any written off amounts for charges that were billed to a bill page, or the like.
If adjustments have previously been made to the account associated with the subscriber line 17, the processor module 54 generates codes 1 to 5 (see operation 118) to indicate to the vendor 12 that the adjustments have previously been made. If no adjustments have been made, the processor module 54 checks to see whether or not the subscriber line number has a business line indicator as shown at operation 120. If the business line indicator is active, the system 10 generates a code 70 (see operation 122), which is communicated to the vendor 12 to advise that the line is a business line. Thereafter, as shown in operation 124, the processor module 54 may check to see if the subscriber line number has been in service for less than about 90 days and, if so, a return code 80 (see operation 126) is generated to advise the vendor 12 who may then selectively decide whether or not to conclude the transaction. A database of new numbers may be updated with the new number.
Thereafter, the system 10 may interrogate the ANI watch database 48 (see operation 128) to ascertain whether or not the area code of the line number has been changed or is scheduled to change. In one embodiment, this interrogation is for billing purposes only and is not used to decide upon the validity of the request. In this operation, the vendor 12 requesting the validation updates the billing file with the new area code number, and the processor module 54 generates a code 110 (see operation 130) to advise the vendor 12 of the scheduled change to the area code.
Once the line number has passed all the aforementioned checks, the system 10 may conclude that the subscriber line 17 is in fact a billable subscriber line based on the data obtained using ANI techniques and, accordingly, the transaction may be charged directly to the account of the subscriber. Accordingly, the system 10 then generates a code 000 (see operation 134) which is communicated to the vendor 12. The code 000 may define an approved status following both a billable line number inquiry as well as several fraud checks which are carried out by the fraud control module 132 (see FIG. 1). If the subscriber line number of the subscriber line 17 has passed the abovementioned checks and a return code 000 is generated, the procedure shown in FIG. 4 is carried out whereafter the process terminates at operation 136. Thus, operation 136 may define the end of the process during which the various checks have been conducted on the subscriber line 17 to assess whether or not it is a billable subscriber line that charges may be billed to. Operation 138 defines, in one embodiment, the last operation to which the process jumps when, at any point during the abovementioned process, the line number is found not to be billable (or a creditworthiness decision is requested) and the inquiry is accordingly terminated and the relevant code is communicated to the vendor 12.
In one exemplary embodiment, the abovementioned operations are executed in real-time. However, information sources that do not allow checks on the line number in real time may be carried out subsequently on the subscriber line number. In one embodiment, once the real-time evaluation is carried out and the return code 000 is communicated to the vendor 12, and should the vendor 12 decide to proceed with the transaction, transaction data is then returned to the system 10 by the vendor 12 for a pre-billing validation check or actual billing. During the actual billing, the system 10 may access an account folder of the subscriber line at the Telco and insert the charges due to the vendor 12 for its goods or services. As shown at operation 140, subscriber line numbers may be sent to the CARE database 46 to determine if the BNA is available at the local Telco. If the folder is not available, the local Telco sends the BNA and codes as to why the number is unavailable. If the BNA is found in the CARE database 46, the processor module 54 may then check to see whether or not the account was created within the last 90 days as shown at operation 142. If the account was not created within the last 90 days, then the business indicator is checked as shown at operation 144 and the process ends as previously shown at operation 146. If, however, the number was found in the CARE database 46, the account was created within the last 90 days, or has an active business indicator, then the system 10 may generate the appropriate codes, which are communicated to vendor 12, and the process terminates as shown at operation 148.
The above process has been described in terms of modified codes set out in Table 2 but, it is to be appreciated, that any other defined set of corresponding codes may be provided so long as the codes are mapped onto, or generated in response to, any one or more of the industry standard LIDB codes.
A summary of the codes generated by one exemplary embodiment of the system 10 during execution of the validation process is provided in Table 1 below.

Table 2 (see below) provides the various actions, which are executed in response to a modified validity code. The table provides an exemplary description and explanation of each code. Return codes 001 to 179 relate to failure codes, which are generated by the system 10 prior to investigation of the LIDB host 52. Return codes 180 to 451 are generated during the LIDB code checks. In the event of the subscriber line 17 failing the checks carried out on it, the system 10 provides optional use of a credit card and, accordingly, Table 2 sets out codes which the system 10 generates in response to executing a standard credit card enquiry for a particular transaction. If the system 10, which may be defined by a server and associated databases, is down, codes 994 to 999 are generated and communicated to the vendor.

In the embodiment of the invention depicted in the drawings, regardless of the type of service provider or the type of validation request, clients or vendors may need a profile so that the process or method carried out by the system 10 knows how to treat the request. The client or vendor profile may be set up in a database, which includes the indicators that are set for the type and tests for each request, which will be subsequently received from the vendor.
The first table shows the operations in the BTN test descriptions process. In one exemplary embodiment, a set of core tests is run for each client. Additionally, clients may have some configuration options to identify the tests that best fit their program.

On/Offnet Family Tables (Billing Coverage)
The OFFNET table family contains OCN & NPA_NXX combinations where billing is not approved. If found, the BTN does not continue on the validation path.
The ONNET table determines if an NPA_NXX & OCN combination can be found among the billable combinations. In this case a match allows the BTN to move further on the validation path. A no match will return a failure.
The CLEC table consists of CLECs that the proprietor, or user of the system 10, does not have billing contracts with. This table is specific to the line number. Sources dictate the fields that will be present for the record. A match here is considered a fail and does not continue.
The 4250 Block table consists of specific line numbers that cannot be billed for 4250-01 record types. A match in this table stops the validation movement.
Bill Control Family Tables
The Unbills or unbillable table holds all the BTNs that have been sent to a subscribers' bill page but could not be placed on the bill page for various reasons. A match here halts the validation sequence for the subject BTN.
Block and cancel tables identify BTNs that have requested a permanent or a Client specific block for billing. A match sends a failed response.
Validation Cache is a table that holds responses in order not to process duplicates (e.g. Submit pressed 10 times). A match here will return the code stored from a previous request.
LIDS Family Tables
LIDB is a third party that supplies information to the phone line number level. The goal is to test and store as many relevant fields as can be requested in a transaction.
The LIDB Validity Table translates the LIDB code into a billable or non-billable response according to predefined business rules. A fail here will halt the validation for the request.
The State specific table is a conversion from a true OCN to a known State Specific OCN that is billable. A match here will trigger the conversion, the BTN continues in the validation process.
The transaction log is the history of each transaction request and response that is processed through the validation system.
The TPM indicates that an NPA is in the permissive dialing period. A match here appends the record with the updated number for a record update.
The ANI Watch has BTNs that have been given an adjustment for charges by the Client, proprietor or user of the system 10 or the Telco. This is to help the client determine the credit score for the BTN.
Unlike the conventional use of the LIDB database that uses the LIDB data to obtain information on a destination/termination or recipient location or subscriber unit, the system 10, in one exemplary embodiment, uses the industry standard LIDB database to obtain relevant information on the initiating subscriber line. The subscriber line reference data obtained from the LIDB database is then processed to generate modified validity codes, which provide a vendor with data to facilitate deciding whether or not a transaction should be processed. The LIDB/LNP database may be queried as if a collect call event is occurring and a call is thus mimicked. The processing of the transaction, in one exemplary embodiment, involves communicating the relevant transaction data to a folder of the subscriber with a relevant Telco. The method of, and system 10 for, validating the billing account associated with the subscriber line allows, for example, a subscriber line to be used to validate and conclude a transaction instead of using a conventional payment techniques such as a credit card, debit card, bank account details or the like.
A current industry-wide problem is the lack of ability of a service provider to identify when a line subscriber has switched his service to a CLEC since the service provider may not have an existing billing arrangement with such a CLEC and may also not have a source for the BNA to allow for a direct billing solution. LNP databases were originally established for the purpose of directing call routing activities among facilities-based carriers and most telephone numbers ported to a CLEC do not involve a facility change (i.e. the CLEC is simply reselling the incumbent LEC's facilities). This means that, for billing decision purposes, LNP queries may provide an incorrect response.
In one embodiment of the present invention, the LNP queries have been enhanced by analyzing and interpreting other field elements included within the query response. Specifically, certain values or, in some cases, the absence of certain values, in the Operating Company Number (“OCN”) and/or the Regional Accounting Office (“RAO”) fields, allows further accuracy in the validation response. While the definitions of the OCN and RAO field elements can be obtained from industry sources, their interpreted use in the validation process is unique to the present invention. Use of these additional data elements can improve the reliability of the validation event.
In addition, the present invention may include supplementing LNP results with CARE queries in LEC regions where LNP results are inadequate and CARE costs are not otherwise prohibitive based on the retail price of the underlying service. CARE may provide a reliable result on CLEC-ported numbers since its basic purpose is to provide subscriber account information (such as billing name and address). Once a number is ported to a CLEC, the incumbent LEC no longer has subscriber responsibility and will, therefore, return an “unavailable” response, even if the LEC's dial-tone facility is still being utilized. This negative response is then used to generate a “deny” status on the subscriber based on the current lack of CLEC billing support.
The exemplary embodiment of the present invention may supplement the validation process through the use of internal databases built from information gathered throughout the billing and collection process and process logic gleaned from previous billing experience.
It is important to appreciate that all of the operations in the method executed by the system 10 need not be executed in real-time. In one exemplary embodiment, after the approval code 000 has been generated by the system 10 at operation 134, the system 10 terminates its pre-validation check routine as shown at operation 136. At this point the system 10 may merely provide pre-validation data or verification data to indicate to the vendor 12 whether or not the subscriber line is billable. Thus the system 10 may, in a first interaction with the vendor 12 provide pre-validation data, and in a second interaction process billing information. During the processing of billing information the validation process may once again be executed. In certain embodiments, the first interaction may be in the form of a registration process during which the validation procedure is carried out to register a subscriber line. The vendor may then conduct numerous transactions with subscriber and subsequent validation checks on the subscriber line may then only be carried out on a periodic basis.
After the validation code has been sent to the vendor 12, and the pre-validation procedure has been completed, the system 10 then carries out the fraud checks on a non real-time basis (usually during the next 48 to 72 hours) as shown in operations 140 to 144. The information obtained during the fraud control check, if necessary, is used to update the various databases. In particular, after a BTN has been successfully validated but before a billing event takes place, the CARE investigation operations 140 to 144 may be executed. In the exemplary embodiment, the system 10 is arranged to interrogate off-site CARE databases and the results of the enquiry are stored in the CARE database 46. Checks on the data received from the CARE databases are then performed; whereafter one or more of the other databases may be updated with the results. For example, the CARE database may be updated with new within 90 days information, business indicator information, or the like. In the exemplary embodiment, CARE codes 2618 and 2619 indicate that the BNA is not available and that the LEC no longer owns the account.
The updating of the databases following the CARE investigation may allow enhanced future checks by the system 10 in a subsequent pre-validation procedure or subsequent registration validation event. The updated information may be provided to the vendor 12. However, if the BTN information returned from the CARE database does not meet predefined criteria, the other databases of the system 10 may not be updated.
In the embodiment described above, information on the subscriber line 17 is forwarded by the service provider or vendor 12 to the system 10 for validation. However, in other embodiments of the invention, the consumer or customer 11 may call the system 10 directly, as shown by line 150 in FIG. 5, and the ANI may then be obtained by the system 10 directly from the customer 11 and not indirectly from the vendor 12. Further subscriber line data, e.g. BTN, address of the customer 11 and so on, may then also be obtained directly from the customer 11. For example, the customer 11 may have appropriate software installed on his/her PC which allows the customer 11 to dial into the system 10 in an automated fashion should he/she wish to charge any requested goods or services to his/her subscriber account. The system 10 would then validate the subscriber line number 17 using the method described above. The system 10 then typically communicates a validation code (e.g. corresponding to approval non-approval) to the vendor 12 as shown by line 152. The vendor 12 would then conclude the transaction with the customer 11 if the subscriber line has been validated.
The proprietor or user of the system 10 may function as a type of clearing house. In particular, the proprietor or user of the system 10 may be responsible or accountable for payment for the goods or services for each transaction to the service provider or vendor 12 and, in turn, receive payment from the Telco 13. As mentioned above, the system 10 may update the telephone bill or account of the subscriber in an automated fashion (see line 154) and the account that the subscriber or customer 11 receives (see FIG. 6 and line 156 in FIG. 5) includes the charges for the goods and/or services provided by the vendor 12. The customer 11 may pay the Telco 13 (see line 155), the Telco 13 may pay the system 10 (see line 156), and the system 10 may pay the vendor 12 (see line 160). It is important to appreciate that these payments need not take place at the same time. In one exemplary embodiment, the payments between the Telco and the system 10, and the system 10 and vendor 12, take place periodically in a batch fashion, causing the machine to perform any one of the methodologies discussed above, may be executed.
FIG. 7 shows a diagrammatic representation of machine in the exemplary form of a computer system 600 within which a set of instructions, for causing the machine to perform any one of the methodologies discussed above, may be executed.
The computer system 600 includes a processor 602, a main memory 604 and a static memory 606, which communicate with each other via a bus 608. The computer system 600 may further include a video display unit 610 (e.g., a liquid crystal display (LCD) or a cathode ray tube (CRT)). The computer system 600 also includes an alpha-numeric input device 612 (e.g., a keyboard), a cursor control device 614 (e.g., a mouse), a disk drive unit 616, a signal generation device 618 (e.g., a speaker) and a network interface device 620.
The disk drive unit 616 includes a machine-readable medium 622 on which is stored a set of instructions (software) 624 embodying any one, or all, of the methodologies or functions described herein. The software 624 is also shown to reside, completely or at least partially, within the main memory 604 and/or within the processor 602. The software 624 may further be transmitted or received via the network interface device 620. For the purposes of this specification, the term “machine-readable medium” shall be taken to include any medium that is capable of storing, encoding or carrying a sequence of instructions for execution by the machine and that cause the machine to perform any one of the methodologies of the present invention. The term “machine-readable medium” shall accordingly be taken to included, but not be limited to, solid-state memories, optical and magnetic disks, and carrier wave signals.
Thus, a method and system to validate data associated with a subscriber line of a telecommunication network have been described. Although the present invention has been described with reference to specific exemplary embodiments, it will be evident that various modifications and changes may be made to these embodiments without departing from the broader spirit and scope of the invention. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
