Abstract

A cellular communication network has a mobile switching center (MSC) that maintains a GPS location data of a mobile handset referenced by a mobile identification number (MIN) and an electronic serial number (ESN) in addition to a geographic cell number in an HLR database for handsets operating in the network. The GPS location data of the handset may be used for efficient paging to a specific cell to route incoming calls to the handset, route emergency responder calls with the physical location of the handset and to program the handset with the handset transmission strength to the nearest cell tower In lieu of using triangulation algorithm.

Claims

1. A cellular communication network based emergency response system, comprising:

a. a mobile switching center (MSC) of a cellular communication network that maintains, in an home location record (HLR) database, in addition to identification of cell towers, a GPS location data of a mobile cell phone device, for devices that are operating in the network;

b. the MSC has an interface to an emergency response (ER) system;

c. the MSC for a received 911 emergency call from a wireless device retrieves the device'"'"'s GPS location data from the HLR database and sends to the ER system over the interface.

2. The network as in claim 1, comprising:

an emergency response logic in the ER system maps the received GPS location data to (i) an ER region contact data from a pre-stored ER region contact database and (ii) maps the GPS location data to a physical address of the device.

3. The network as in claim 2, comprising:

a. the logic creates and sends a record with the ER region contact data and the device'"'"'s physical address data to the MSC over the interface;

b. the MSC receives the record and routs the 911 call to the ER region contact landline;

c. the logic embeds a text/voice message with the physical address of the device or sends a separate text message record.

4. The network as in claim 1, comprising:

the MSC for a received 911 emergency call from a device retrieves the device'"'"'s GPS location data from the HLR database and routs the call with the location data to an ER system.

5. The network as in claim 4, comprising:

a. an emergency responder logic in the ER system, maps the received GPS location data to (i) an ER region contact data and (ii) to a physical address of the device;

b. the logic routs the call to a landline number of the ER region and embeds a text message with the physical address of the handset to the ER region.

6. The network as in claim 1, comprising:

an emergency responder logic in the MSC for a received 911 emergency call from the device retrieves the device'"'"'s GPS location data, maps to a physical address and performs a text to speech conversion of the physical address and embeds the physical address in a routed 911 call to the emergency system.

7. A method for cellular communication network based emergency response system, comprising the steps of:

a. maintaining by a mobile switching center (MSC) of a cellular communication network, in an home location record (HLR) database, in addition to identification of cell towers, a GPS location data of a mobile cell phone device, for devices that are operating in the network;

b. interfacing the MSC to an emergency response (ER) system;

c. retrieving the device'"'"'s GPS location data from the HLR database by the MSC for a received 911 emergency call for the device and sending to the ER system over the interface.

8. The method as in claim 7, comprising the steps of:

mapping by an emergency responder logic in the ER system, the received GPS location data to (i) an ER region contact data and (ii) to a physical address of the device.

9. The method as in claim 8, comprising the steps of:

a. creating by the logic and sending a record with the ER region contact data and the device'"'"'s physical address data to the MSC over the interface;

b. receiving by the MSC the record and routing the 911 call to the ER region contact landline;

c. embedding by the logic a text/voice message with the physical address of the device or sending a separate text message record.

10. The method as in claim 8, comprising the steps of:

a. mapping by an emergency responder logic in the ER system, mapping the received GPS location data to (i) an ER region contact data and (ii) to a physical address of the handset;

b. routing by the logic the call to a landline number of the ER region and embeds a text message with the physical address of the device to the ER region.

11. The method as in claim 8, comprising the steps of:

retrieving the device'"'"'s GPS location data by an emergency responder logic in the MSC for a received 911 emergency call from the handset, mapping to a physical address and performing a text to speech conversion of the physical address and embedding the physical address in a routed 911 call to the emergency system.

12. A method of a cellular communication network operation, comprising the steps of:

maintaining in a mobile switching center (MSC) of a cellular communication network, a GPS location data of a mobile handset, referenced by a mobile identification number (MIN) and an electronic serial number (ESN), in addition to identification of cell towers, in an HLR database for the cell phone devices, operating in the network.

13. The method of network operation as in claim 12, comprising the steps of:

retrieving by an emergency responder logic in the MSC, for a received 911 emergency call, the GPS location data of the device, from the HLR database, and converting the GPS physical data to a physical address, and sending a text message with the physical address to an emergency response system.

14. The method of network operation as in claim 12, comprising the steps of:

retrieving by the emergency responder logic in the MSC, for a received 911 emergency call, the GPS location data of the device from the HLR database, and converting the GPS location data to a physical address, performing a text to speech conversion of the physical address and embedding in the voice call before routing the call to the emergency response system.

15. An emergency response system for a wireless network, comprising:

a. a logic operable in a server of the emergency response system that receives a lat/long data of a received 911 call, of a cell phone device operating in the wireless network, from a mobile switching center of the wireless network;

b. the logic interfaces with a ER database system, the ER database system maps the lat/long data to a physical address and the logic retrieves the device'"'"'s physical address from the database.

16. The ER system as in claim 15, further comprising:

the logic sends the physical address data to the mobile switching center.

17. The ER system as in claim 15, further comprising:

a. the ER database system, also sends to the logic the ER region where the device is located and the landline number of the ER region;

b. the logic sends both the device'"'"'s physical address and the ER region landline number to the mobile switching center for the mobile switching center, thereby the mobile switching center is able to route the 911 emergency call to the specific ER region where the device is located as well as the physical address of the device.

18. The ER system as in claim 15, further comprising:

the ER database system stores the cities in each of the ER regions and the physical addresses in each city along with their lat/long data.

19. The ER system as in claim 15, further comprising:

the ER database system stores ER region details including address and landline contact numbers.

20. The ER system as in claim 15, further comprising:

the ER database system stores for each of the cities in each of the ER regions, the landmarks including parks, highways, libraries, points of interest and their physical addresses along with their lat/long data.
