Systems, methods, devices and arrangements for emergency call services using non-traditional endpoint devices
View Patent ↗A variety of methods, systems, devices and arrangements are implemented for emergency call centers. According to one such method, a location database is populated from a plurality of endpoint devices. The location database determines locations for nodes in a data transmission route from information received from the endpoint devices. Emergency calls using these nodes are located using the populated database.
1. A system comprising:
a plurality of endpoint devices each having
a location circuit configured to provide physical location data about the physical location of the endpoint device;
one or more external ports for communicating data to an external network; and
a processing circuit configured to
generate one or more populating data packets containing the physical location data; and
transmit the populating data packets to a remote location-determination server; and
at least one location-determination server configured to
receive the populating data packets from the plurality of endpoint devices;
determine nodes in a transmission route between the plurality of endpoint devices and the location-determination server;
calculate a physical location for one or more of the determined nodes as a function of the physical location data in the populating data packets;
store the calculated physical location for the one or more of the determined nodes;
identify, in response to an emergency request from an emergency-capable endpoint device without bidirectional audio capabilities, one or more nodes in a transmission route used to send data from the emergency-capable endpoint device;
retrieve calculated physical location data for the identified nodes;
determine a probable physical location for the emergency-capable endpoint device as a function of the calculated physical location data for the identified nodes and a probable location algorithm;
provide the determined probable physical location for the emergency-capable endpoint device to an emergency operator; and
establish a non-audio communications link between the emergency operator and the emergency-capable endpoint device.
2. The system of claim 1 , wherein the emergency-capable endpoint device includes a sealed compartment for holding an emergency circuit when not in use.
3. The system of claim 1 , wherein the emergency-capable endpoint device includes a sealed compartment for holding an emergency key for activation of an emergency circuit.
4. The system of claim 1 , wherein the emergency-capable endpoint device communicates with the emergency operator using SMS or MMS text messaging.
5. The system of claim 1 , wherein the emergency-capable endpoint device communicates with the emergency operator over the Internet.
6. The system of claim 1 , wherein the emergency-capable endpoint device includes a modem used in response to activation of an emergency circuit.
7. The system of claim 1 , wherein at least one location-determination server is further configured to update a current calculated physical location for the one or more of the determined nodes based upon receipt of additional populating data packets and a parameter representing resistance to change from the current calculated physical location.
8. The system of claim 1 , wherein the calculated physical location for one of the determined nodes is a geographic area determined as a function of the probability that an endpoint device connected to one of the determined nodes is within the geographic area.
9. The system of claim 1 , wherein the processing circuit of the plurality of endpoint devices is configured to encrypt data about nodes in a local-area-network (LAN) near the endpoint device and to include the encrypted data in a populating data packet.
