Abstract

A long-distance telephone service system provides for accounting and flexible, customizable control of long-distance telephone usage by customers, especially prepaid long-distance service customers. The system maintains a set of global operating parameters associated with each access number. It further maintains a database of user accounts or card numbers, and a set of card processing parameters associated with each card number. Both the global parameters and the individual card processing parameters are applied in completing a long-distance call to a destination number so as to provide highly flexible control over individual accounts as well as groups of accounts. Establishment of new accounts, and "recharging" the prepaid balance of existing accounts is accomplished automatically from remote locations.

Claims

1. A method for providing long-distance service comprising:

establishing a plurality of different access phone numbers;

preselecting a plurality of different sets of global operating parameters, each preselected set corresponding to a respective one of the access phone numbers;

receiving a telephone call on one of said access phone numbers;

identifying the access phone number called to initiate the received telephone call;

retrieving fie preselected set of global operating parameters corresponding with the identified access phone number called;

collecting a destination telephone number;

completing the call to the destination telephone number in accordance with the retrieved preselected set of global operating parameters;

establishing a plurality of calling card numbers;

associating at least two of said calling card numbers with one of the different access phone numbers;

preselecting a plurality of different groups of processing parameters, each preselected group corresponding to a respective one of the calling card numbers;

collecting a credit card number;

identifying the credit card number collected;

retrieving the preselected group of processing parameters corresponding with the identified credit card number;

comparing the collected destination telephone number to the retrieved processing parameters; and

processing the call to the destination telephone number in accordance with the retrieved processing parameters.

2. A method according to claim 1 wherein the retrieved set of global operating parameters include a selectable minutes key and the retrieved group of processing parameters including an account balance, the method further comprising:

providing a default cost per minute rate;

retrieving the account balance;

determining an estimated number of minutes remaining on the identified credit card number, said estimated number being equal to the account balance divided by the default cost per minute rate; and

announcing the estimated number of minutes remaining if the minutes key is activated.

3. A method according to claim 1 wherein the retrieved global operating parameters include one or more message controls and further comprising playing one or more audio messages as indicated by the message controls.

4. A method according to claim 3 wherein said playing audio messages includes playing a first message for greeting or instructing the caller if indicated by the message controls.

5. A method according to claim 3 wherein said playing messages includes playing a second message comprising an international warning if indicated by the message controls and if the collected destination telephone number indicates an international call.

6. A method according to claim 3 wherein said playing audio messages includes playing a user-selectable information message if indicated by the message controls.

7. A method according to claim 3 wherein said playing audio messages includes playing a remaining amount of talk time based on destination and balance amounts if indicated by the message controls.

8. A method according to claim 3 wherein said playing audio messages includes playing an international charge rate if indicated by the message controls and if the collected destination telephone number indicates an international call.

9. A method according to claim 3 wherein said playing audio messages includes playing a predetermined brand announcement if indicated by the message controls, the brand announcement being associated with the identified access number.

10. A method according to claim 1 further comprising collecting a project code if indicated by the retrieved set of global operating parameters.

11. A method according to claim 1 wherein the retrieved global operating parameters include one or more of:

a log path, a bad card path, a brand name, a voice path, V&

H billing, a time out on no answer, reoriginate characters, number of retries, PIN key, speed key, redial key and a backup path.

12. A method according to claim 1 wherein the retrieved group of processing parameters including an account balance, the method further comprising decrementing the account balance in real time while the call is in progress.

13. A method according to claim 1 wherein the retrieved processing parameters include an account balance or a charge limit, the method further comprising:

computing a single call time or charge limit responsive to the retrieved account balance or charge limit and responsive to a predetermined destination rating;

while the completed call is in progress, substantially continuously comparing the call to the single call limit; and

immediately terminating the call if and when the call time or charges meet the single call limit.

14. A method according to claim 13 wherein the retrieved global operating parameters include a specified warning time, and further comprising playing a predetermined warning message at the warning time prior to said terminating the call.

15. A method according to claim 1 wherein the processing parameters include an indication of card type, the method further comprising obtaining authorization to charge the long-distance telephone service to the collected calling card number if the card type is a credit card.

16. A method according to claim 1 wherein the card processing parameters include a project code identifier.

17. A method according to claim 1 wherein the card processing parameters include an indication of international calling permission, the method further comprising not completing the call if the destination telephone indicates an international call and the processing parameters indicate that international calling permission is denied.
