Abstract

Systems and methods for providing a user with access to emergency services are described. A cable modem/multimedia terminal adapter employing voice over internet protocol (VoIP) can be configured to provide access to emergency services during periods of unavailability of a connection to a network due to software upgrades of the cable modem/multimedia terminal adapter or a VoIP handset, a power outage or a malfunction of the cable modem/multi-media terminal adapter or the VoIP handset. Access to emergency services can be provided through the use of a dedicated button on the cable modem/multimedia terminal adapter and the use of dedicated hardware in the cable modem/multimedia terminal adapter that is configured to initiate operation when a connection to the network is unavailable.

Claims

1. A method, comprising:

recording receipt of an emergency event when a connection to a network is unavailable; and

transmitting a message indicating that the emergency event has occurred through the network in response to determining that the connection has become available.

2. The method of claim 1, further comprising:

counting elapsed time between receipt of the emergency event and transmitting the message; and

appending the elapsed time to the message.

3. The method of claim 1, further comprising:

recording content of the message prior to receipt of the emergency event, wherein the content is provided by a user.

4. The method of claim 1, wherein the message is a specialized extension of a protocol used to communicate on the network.

5. The method of claim 1, further comprising:

providing a user with options corresponding to different categories of emergency events, wherein the emergency event is received in accordance with a user-selected option.

6. The method of claim 1, wherein the message is a request for an emergency service that is at least one of a medical service, a fire response service or a police service.

7. The method of claim 6, wherein the message includes personal information about the user.

8. A network communication system comprising:

a network interface for connecting to a network; and

a controller connected to the network interface and configured to determine the availability of a network connection, to record receipt of an emergency event when a connection to the network is unavailable, and to direct the network interface to transmit a message indicating that the emergency event has occurred in response to determining that the connection has become available.

9. The system of claim 8, further comprising:

a user interface configured to receive an emergency event, wherein the user-interface includes an interface for connecting to a handset to enable voice communication through the network using voice over internet protocol and wherein unavailability of the connection to the network is due to a malfunction of the handset.

10. The system of claim 8, further comprising:

a counter configured to count elapsed time between receiving the emergency event and transmitting the message, wherein the controller is further configured to append the elapsed time to the message.

11. The system of claim 8, wherein the unavailability of the connection to the network is due to at least one of a software upgrade in the system, a power failure or a software failure.

12. The system of claim 8, further comprising:

non-volatile memory for storing the indication.

13. The system of claim 8, wherein the controller further comprises:

a dedicated module configured to activate operation in response to the unavailability of the network connection, to monitor the user-interface to determine whether any indication of an emergency event has been received, to direct recordation of any received indications and to direct the network interface to transmit the message.

14. The system of claim 13, further comprising:

a backup battery configured to power the dedicated module.

15. The system of claim 13, wherein the controller is implemented in at least one of a cable modem or a multi-media terminal adapter.

16. The system of claim 15, wherein the user-interface is at least one button dedicated for notifying emergency service-providers of the emergency event.

17. The system of claim 15, wherein the network interface further comprises interfaces to a plurality of dedicated emergency-service provider networks and wherein the message is transmitted on at least one of the dedicated emergency-service provider networks.

18. A system comprising:

a telephone handset; and

a network terminal configured to connect the telephone handset to a network and to enable communications using voice over interne protocol, the network terminal further comprising;

a user-interface configured to receive an indication of an emergency event as an alternative to receiving the indication via the telephone handset if communication capability via the telephone handset is unavailable, and

a controller configured to direct the terminal to transmit, over the network, a message indicating that the emergency event has occurred.

19. A method comprising:

servicing a plurality of calls in accordance with a maximum-lines-in-use constraint;

determining that at least one of the plurality of calls is for contacting at least one emergency service provider while a number of calls serviced is at the maximum-lines-in-use constraint;

disconnecting at least one of the calls serviced; and

opening at least one call connection to contact at least one emergency service provider.

20. The method of claim 19, wherein the determining further comprises cross-referencing a number dialed with a telephone number of an emergency service provider.
