Abstract

A system and method for capturing emergency data messages in a network environment includes receiving, at a first network node, an emergency data message communicated from a wireless communications device. The emergency data message may be accompanied by an origination address and destination address indicative of an emergency network address. A determination may be made at the first network node to determine whether the origination address matches a monitored address established by a law enforcement agency to capture data messages to or from the origination address. If it is determined that the origination address matches the monitored address, then a copy of the emergency data message may be routed to a second network node for collection of the emergency data message and the emergency data message may be routed to the destination address. Otherwise, the emergency data message may be routed to the destination address.

Claims

1. A method for capturing emergency data messages in a network environment, said method comprising:

receiving, at a first network node, an emergency data message communicated from a wireless communications device, the emergency data message being accompanied by an origination address and destination address indicative of an emergency network address;

determining, at the first network node, whether the origination address matches a monitored address established by a law enforcement agency to capture data messages to or from the monitored address; and

if the origination address matches the monitored address;

routing a copy of the emergency data message to a second network node for collection of the emergency data message; and

routing the emergency data message to the destination address;

otherwise, routing the emergency data message to the destination address.

2. The method according to claim 1, further comprising:

receiving, at the first network node, an emergency data message response from a PSAP having a destination address for the wireless communications device;

determining that the destination address matches the monitored address; and

in response to determining that the destination address matches the monitored address;

routing a copy of the emergency data message response to the second network node; and

routing the emergency data message response to the wireless communications device.

3. The method according to claim 1, wherein receiving the emergency data message at the first network node includes receiving the emergency data message at a switching gateway operating on the communications network and in communication with the second network node, which is a server operated by the law enforcement agency.

4. The method according to claim 1, wherein receiving an emergency data message includes receiving a text message.

5. The method according to claim 1, wherein receiving a destination address includes receiving an Internet domain name address.

6. The method according to claim 1, further comprising routing the emergency data message via an ATM network to a PSAP.

7. The method according to claim 1 further comprising, in response to receiving the emergency data message:

time stamping the emergency data message; and

communicating the time stamp to the second network node.

8. The method according to claim 1, wherein receiving an emergency data message further includes receiving a short code with the emergency data message;

and

further comprising prioritizing the emergency data message ahead of non-emergency data messages based on the short code.

9. A system for capturing emergency data messages in a network environment, said system comprising:

a memory;

an input/output (J/O) unit;

a processing unit in communication with said memory and I/O unit, and configured to;

receive, at a first network node, an emergency data message communicated from a wireless communications device, the emergency data message being accompanied by an origination address and destination address indicative of an emergency network address;

determine, at the first network node, whether the origination address matches a monitored address established by a law enforcement agency to capture data messages to or from the monitored address; and

if the origination address matches the monitored address;

route a copy of the emergency data message to a second network node for collection of the emergency data message; and

route the emergency data message to the destination address;

otherwise, route the emergency data message to the destination address.

10. The system according to claim 9, wherein said processing unit is further configured to:

receive, at the first network node, an emergency data message response from a PSAP having a destination address for the wireless communications device;

determine that the destination address matches the monitored address; and

in response to determining that the destination address matches the monitored address;

route a copy of the emergency data message response to the second network node; and

route the emergency data message response to the wireless communications device.

11. The system according to claim 9, wherein said processing unit is being operated by a switching gateway operating on the communications network and in communication with the second network node, which is a server operated by the law enforcement agency.

12. The system according to claim 9, wherein the emergency data message is a text message.

13. The system according to claim 9, wherein the destination address is an Internet domain name address.

14. The system according to claim 9, wherein said processing unit is further configured to route the emergency data message via an ATM network to a PSAP.

15. The system according to claim 9, wherein said processing unit is further configured to, in response to receiving the emergency data message:

time stamp the emergency data message; and

communicate the time stamp to the second network node.

16. The system according to claim 11, wherein said processing unit is further configured to receive a short code with the emergency data message and, based on the short code, prioritize the emergency data message ahead of non-emergency data messages.

17. A method for capturing data messages in a network environment, said method comprising:

receiving, at a first network node, a data message communicated from a wireless communications device, the data message being accompanied by an origination address and destination address indicative of an emergency network address;

determining, at the first network node, whether the origination address matches a monitored address established by a law enforcement agency to capture data messages to or from the monitored address; and

if the origination address matches the monitored address;

routing a copy of the data message to a second network node for collection of the data message; and

routing the data message to the destination address;

otherwise, routing the data message to the destination address.

18. The method according to claim 17, wherein receiving the data message includes receiving a text message.

19. The method according to claim 17, wherein routing the data message to the destination address includes routing the data message to a destination address associated with another wireless communications device.

20. The method according to claim 17, further comprising time stamping the data message and communicating the time stamp with the data message to the second network node.
