Abstract

A method and system for transmission of control information over a separate channel to devices connected to a telecommunications network. An outdial node couples a destination system to a user who is accessing the destination system using a first communications pathway through a telecommunications network. When the destination system requests control data be entered, the user causes a signal to be transmitted on a second communications pathway. The signal, which includes information identifying the user and the desired control function, is transmitted by the user from a two-way pager. The signal is received by a paging system and transmitted to the outdial node. The outdial node accesses a database using the user identifying information and selects an entry corresponding the user and to the control function. The control data contained in the selected entry is then output to the destination system.

Claims

1. A method of secure transmission of control information to a destination system comprising the steps of:

establishing communications with a first user station, using a first communication pathway;

establishing communications with the destination system;

receiving a request for control information from the destination system;

transmitting the received request for control information to the user station over the first communication pathway;

receiving a signal from a second user station, using a second communication pathway, the signal including an indicator of control information; and

transmitting the indicated control information to the destination system.

2. The method of claim 1, further comprising the step of preventing the control information from being transmitted over the first communication pathway.

3. The method of claim 1, wherein the second user station is a two-way pager and the second communication pathway includes a paging channel.

4. The method of claim 1, wherein the signal includes an indicator of a user and an indicator of a function to be performed.

5. The method of claim 4, wherein the step of transmitting the indicated control information comprises the steps of:

determining the control information based on the indicated user and function to be performed, and

transmitting the determined control information.

6. The method of claim 5, wherein the step of determining the control information comprises the steps of:

accessing a database containing a plurality of records, each record comprising user information, function information, and control information for the destination system; and

selecting the record corresponding to the indicated user and the indicated function.

7. The method of claim 1, wherein the first user station is a telephone and the first communication pathway is an audio channel established by placing a telephone call from the first user station.

8. The method of claim 7, wherein the destination system is coupled to the outdial node by an audio channel.

9. The method of claim 8, wherein the step of transmitting the indicated control information comprises the step of transmitting the control information to the destination system using a touch-tone signal.

10. The method of claim 9, further comprising the step of preventing the control information from being transmitted over the first communication pathway.

11. The method of claim 7, wherein the destination system is coupled to the outdial node by a data channel.

12. The method of claim 11, wherein the step of transmitting the indicated control information comprises the step of transmitting the control information to the destination system using a data signal.

13. The method of claim 12, wherein the received request for control information is a data signal and the step of transmitting the received request for control information comprises the steps of:

translating the received data signal to an audio prompt; and

transmitting the audio prompt to the user station.

14. An outdial system for transmitting control information from a user to a destination system, the outdial system coupled to a first user station over a first communication pathway, to a second user station over a second communication pathway and to the destination system, the outdial system comprising:

a first receiver receiving a request for control information from the destination system;

a first transmitter transmitting the received request for control information to the first user station;

a second receiver receiving a signal including an indicator of control information from the second user station; and

a second transmitter transmitting the indicated control information to the destination system.

15. The system of claim 14, further comprising a device which prevents the control information from being transmitted over the first communication pathway.

16. The system of claim 14, wherein the second user station is a two-way pager and the second communication pathway includes a paging channel.

17. The system of claim 14, wherein the signal includes an indicator of a user and an indicator of a function to be performed.

18. The system of claim 17, further comprising a database comprising a plurality of records, each record comprising user information, function information and control information for the destination system, the database receiving the signal from the second receiver, selecting the record corresponding to the indicated user and function, and transmitting the indicated control information to the second transmitter.

19. The system of claim 14, wherein the first user station is a telephone and the first communication pathway is an audio channel established by placing a telephone call from the first user station.

20. The system of claim 19, wherein the destination system is coupled to the outdial system by an audio channel.

21. The system of claim 20, wherein the second transmitter comprises a touch-tone signal transmitter.

22. The system of claim 21, further comprising a device which prevents the control information from being transmitted over the first communication pathway.

23. The system of claim 19, wherein the destination system is coupled to the outdial system by a data channel.

24. The system of claim 23, wherein the second transmitter comprises a data signal transmitter.

25. The system of claim 24, wherein the first receiver comprises a data signal receiver receiving the request for control information and the first transmitter comprises a translation device translating the received request to an audio prompt.
