Abstract

An outage notification system is provided which includes a first communication network, a second communication network, a plurality of first communication units communicatively coupled to the first communication network and the second communication network, a network monitoring unit communicatively coupled to the first communication network and configured to detect a failure in at least one of the plurality of first communication units or the first communication network, a plurality of second communication units communicatively coupled to the second communication network and associated with corresponding first communication units, and a message alert unit communicatively coupled to the first and second communication networks and configured to receive an alert notification from the network monitoring unit via the first communication network indicating a failure in at least one of the first communication units or the first communication network.

Claims

1. An outage notification system comprising:

a first communication network communicatively coupling a plurality of first communication units;

a second communication network communicatively coupling a plurality of second communication units;

a network monitoring unit communicatively coupled to the first communication network and configured to detect a failure in at least one of the plurality of first communication units or the first communication network;

the plurality of second communication units communicatively coupled to the second communication network and operable to communicate with the first communication network only through the second communication network, wherein each of the second communication units is associated with a corresponding one or more of the first communication units, the plurality of first communication units is of a first type of device and the plurality of second communication units is of a second type of device, the first type and the second type being different; and

a message alert unit communicatively coupled to the first communication network and the second communication network, the message alert unit configured to receive an alert notification from the network monitoring unit via the first communication network indicating a failure in at least one of the first communication units or the first communication network, the alert notification to the message alert unit from the network monitoring unit includes an indicator of a type of failure and a general location on the first communication network where the failure is occurring in response to detecting that the failure is occurring within the first communication network, wherein, the message alert unit is configured to extract a location indicator and a failure type from the alert notification, querying a communications address list for first communications units affected by the failure, store the results of the communications address list query as a distribution list, perform a second query of the communications address list for second communications units assigned to the first communication units in the distribution list, insert the results of the second communications address list query into the distribution list and transmit a message via the second communication network without traversing the first network to the second communication units associated with at least one of the first communication units included on the distribution list, wherein the network monitoring unit and message alert unit are both located within a network operation center, while the plurality of first communication units and the plurality of second communication units are located outside the network operation center.

2. The outage notification system of claim 1, wherein the first communication network is a cable television network or a satellite television network.

3. The outage notification system of claim 1, wherein each of the first communication units is further communicatively coupled to the second communication network.

4. The outage notification system of claim 1, wherein the second communication network is a wireless computer network or a wireless cellular network.

5. The outage notification system of claim 1, further comprising:

a plurality of display units each communicatively coupled to the plurality of second communication units, wherein, each of the second communication units provides the message to the associated display unit.

6. The outage notification system of claim 1, wherein the network monitoring unit determines which of the plurality of second communication units receives the message.

7. The outage notification system of claim 1, wherein the message alert unit determines which of the plurality of second communication units receives the message.

8. The outage notification system of claim 1, wherein the message alert unit sends the message to the second communication units as a short message service.

9. The outage notification system of claim 1, wherein the alert notification is manually sent to the message alert unit via the first network.

10. The outage notification system of claim 1, wherein each of the second communication units are a cellular phone or a wireless e-mail communication device.

11. A method of notifying a plurality of first communication units and second communication units of a communication failure comprising the steps of:

detecting a failure in the one of a plurality of first communication units or a first communication network providing service to the plurality of first communication units via a network monitoring unit communicatively coupled to the first communication network;

sending an alert notification from the network monitoring unit to a message alert unit via the first communication network;

extracting a location indicator and a failure type from the alert notification at the message alert unit;

querying a communications address list for first communications units affected by the failure;

storing the results of the communications address list query as a distribution list;

performing a second query of the communications address list for second communications units assigned to the first communication units in the distribution list;

inserting the results of the second communications address list query into the distribution list;

selecting a message stored on the message alert unit based on the alert notification; and

transmitting the message from the message alert unit via a second communication network to the first communication units and the second communication included on the distribution list;

wherein the network monitoring unit and message alert unit are both located within a network operation center, while the plurality of first communication units and the plurality of second communication units are located outside the network operation center.

12. The method of claim 11, wherein, the message alert unit is configured to select the message from a plurality of messages stored on the message alert unit based on the type of failure.

13. The method of claim 11, further comprising the steps of:

transmitting a restoration message via the message alert unit over one of the first communication network and second communication network after the failure is corrected.

14. The method of claim 11, wherein, the first communication network is a cable television network, a satellite television network, an internet television network or a computer network.

15. The method of claim 11, wherein, the second communication network is a wireless computer network or a wireless cellular network.

16. The method of claim 11, further comprising the steps of:

providing the message to a display unit communicatively coupled to each of the first communication units and second communication units.

17. The method of claim 11, wherein the network monitoring unit determines which of the plurality of first communication units and second communication units receives the message.

18. The method of claim 11, wherein the message alert unit determines which of the plurality of first communication units and second communication units receives the message.

19. The method of claim 11, wherein the message alert unit transmits the message to the first communication units and second communication units as a short message service, an electronic mail message or a simple network message protocol message.

20. The method of claim 11, wherein the alert notification is manually transmitted to the message alert unit via the first communication network.

21. The method of claim 11, wherein the second communication unit is a cellular phone or a wireless e-mail communication device.
