Abstract

The present invention provides a system and method for voice based network management. A network management system uses voice based scripts that allow network management operations to be performed over a phone. In one embodiment, the voice based scripts use a Voice Extensible Markup Language (VXML). However, the voice based script can be any form of communication that allows a user to conduct network management operations using Dual Tone Multi-Frequency (DTMF) signaling or speech commands.

Claims

1. A system comprising:

a network management device to receive an inbound call remotely initiated by a voice interface device located remotely with respect to the network management device, the inbound call received without prompting by the network management device such that the inbound call is initiated by the voice interface device and not the network management device;

the network management device to use voice scripts to generate speech verbally presenting network management options over the received call;

the network management device to monitor for verbal network management requests received responsive to presenting the verbal network management options; and

the network management device to convert the verbal network management requests received over the inbound call into electronic text and to use the electronic text for conducting network management operations;

wherein the network management device is a computer operable to remotely reconfigure a router, switch, gateway or other network device.

2. A system according to claim 1 further comprising:

the network management device to receive, over the inbound call, an automatic number identification that corresponds to the voice interface device;

the network management device to conduct the network management operations when there is authorization based on the comparison.

3. A system according to claim 2 further comprising:

the voice interface device to transfer an inputted personal identification number over the inbound call to the network management device, the inputted personal identification number corresponding to a user of the voice interface device;

the network management device to receive, over the inbound call, the inputted personal identification number that corresponds to the user;

the network management device to determine based on the received personal identification number whether the user of the voice interface device is an authorized user; and

the network management device to use the electronic text for conducting network management operations only when there is authorization based on the comparison and when the user of the voice interface device is authorized.

4. A system according to claim 3 wherein the voice interface device is a Voice over Internet Protocol (VoIP) phone.

5. A system according to claim 3 wherein the verbal network management requests comprise speech.

6. A system according to claim 1 wherein the network management device uses the electronic text to generate verbal prompts for initiating the network management operations and to communicate network component configuration information responsive to the network management operations.

7. A system according to claim 1 including a component access device for querying network components for status information.

8. A system according to claim 7 wherein the component access device is part of the network management device or a stand alone server.

9. A system according to claim 7 wherein the component access device includes a lookup table identifying IP addresses for the network components and associated access protocols used for conducting the network management operations.

10. A system as in claim 1 including a file server containing the electronic text for verbally identifying the network management operations and reporting results of the network management operations.

11. A system according to claim 1 wherein the electronic text is in VxML (Voice Extensible Markup Language).

12. The system according to claim 1 wherein the network is the Publicly Switched Telephone Network (PSTN).

13. The system according to claim 1 wherein the automatic number identification is provided by a Dialed Number Identification Service (DNIS).

14. A method of performing a network management operation, comprising:

generating voice scripts using management information received across a network over a remotely initiated connection that is initiated using a phone;

using the voice scripts to identify and initiate network management operations for a network processing device;

conducting network management operations on the network processing device according to phone responses to the voice scripts, the phone responses being received over the remotely initiated connection; and

using the voice scripts to report the results of the network management operations back to the phone over the remotely initiated connection.

15. A method according to claim 14 including using the voice scripts to generate speech verbally presenting network management options over the phone, the network management options including pinging a network component to determine if it is up and available, providing information on the interfaces of a router or restarting a router.

16. A method according to claim 15 including using a VxML (Voice Extensible Markup Language) for generating the voice scripts.

17. A method according to claim 14 including receiving speech or DTMF (Dual Tone Multi-Frequency) signals as responses to the voice scripts.

18. A method according to claim 17 including converting the speech or DTMF signals into computer readable text and using the text for conducting the network management operation on the network processing device.

19. A method according to claim 18 including identifying an Internet Protocol (IP) address for the network processing device in the text and using the IP address to identify a network management query protocol supported by the network processing device.

20. A method according to claim 19 including using the query protocol to obtain status information for the network processing device, converting the status information into speech, and sending the speech to the phone.

21. A method according to claim 14 including using the voice based scripts and voice commands from the phone to identify operating status and load conditions for an IP router.

22. The method according to claim 14 wherein the network is the Publicly Switched Telephone Network (PSTN).

23. The method according to claim 14 further comprising generating the voice scripts after verifying that a user of the phone is authorized.

24. The method according to claim 23 further comprising:

identifying a phone number belonging to the phone; and

determining that the remotely initiated connection is authorized when the identified phone number matches a stored authorized phone number.

25. The method according to claim 24 wherein Automatic Number Identification (ANI) or Dialed Number Identification Service (DNIS) is used to identify the phone number.

26. The method according to claim 14 further comprising:

receiving a user identification number over the remotely initiated connection, the user identification number identifying a user of the phone; and

determining that the user is authorized based on the user identification number and when the remotely initiated connection is authorized by verifying a phone number of the phone.

27. A system of performing a network management operation, comprising:

means for generating voice scripts in a first network using management information included in an inbound call that is initiated from a remote second network, the inbound call being unsolicited and initiated from the second network and not the first network;
