Computer-implemented method of processing an emergency call and emergency communication network

1. A computer-implemented method of processing an emergency call in an emergency communication network comprising:

receiving, at an Emergency Service Routing Proxy (ESRP), an emergency call from a first mobile communication device, the emergency call being received via a Session Initiation Protocol (SIP) INVITE message;

obtaining location information of a location of the first mobile communication device;

determining a Public Safety Answering Point (PSAP) that is in a vicinity of the location of the first mobile communication device, wherein the vicinity of the first mobile communication device is classified as being a communication device in a same cell-ID (CID) as the first mobile communication device

forwarding the emergency call to the PSAP for being handled by a call taker at the PSAP,

requesting, by the ESRP, location information of all mobile communication devices that are in the vicinity of the first mobile communication device,

upon receipt of the location information, creating a list of all mobile communication devices that are in the vicinity of the first mobile communication device,

transmitting the list to the PSAP to be displayed at a display device of a call taker at the PSAP handling the emergency call.

2. The method of claim 1 , comprising:

selecting, from the list, a mobile communication device that is closest to the first mobile communication device.

3. The method of claim 2 , comprising:

establishing a conference bridge between the first mobile communication device of the emergency caller and the call taker at the PSAP and adding the mobile communication device selected from the list to the conference bridge.

4. The method of claim 3 , comprising:

adding a first response attendant to the conference bridge.

5. The method of claim 2 , comprising:

sending a request for assistance in the reported emergency incidence to the mobile communication device selected from the list.

6. The method of claim 2 , comprising:

requesting a cell-ID (CID) of the first mobile communication device for identifying each base transceiver station (BTS) or sector of a BTS within a location area code (LAC).

7. The method of claim 2 , comprising:

displaying a map on which the emergency incident location and co-located mobile communication devices are displayed.

8. The method of claim 7 , wherein the map also comprises indications of emergency facilities in the vicinity of the emergency incident location.

9. The method of claim 1 , wherein the location information either is provided by value or by reference.

10. The method of claim 1 , comprising: continuously updating the list to account for communication devices in the same CID as the first communication device.

11. The method of claim 10 , comprising:

refreshing a map on which the emergency incident location and the mobile communication devices that are in the vicinity of the first mobile communication device included in the list are displayed based on the updated location information of the communication devices located in the vicinity of the first communication device.

12. A computer-implemented method of processing an emergency call in an emergency communication network comprising:

receiving, at an Emergency Service Routing Proxy (ESRP), an emergency call from a first mobile communication device, the emergency call being received via a Session Initiation Protocol (SIP) INVITE message;

obtaining location information of a location of the first mobile communication device;

determining a Public Safety Answering Point (PSAP) that is in a vicinity of the location of the first mobile communication device,

forwarding the emergency call to the PSAP for being handled by a call taker at the PSAP,

requesting, by the ESRP, location information of all mobile communication devices that are in the vicinity of the first mobile communication device,

upon receipt of the location information, creating a list of all mobile communication devices that are in the vicinity of the first mobile communication device,

transmitting the list to the PSAP to be displayed at a display device of a call taker at the PSAP handling the emergency call;

requesting a cell-ID (CID) of the first mobile communication device for identifying each base transceiver station (BTS) or sector of a BTS within a location area code (LAC); and

requesting the ANI of all mobile communication devices in the CID of the first mobile communication device.

13. The method of claim 12 , comprising:

requesting, with the ANI of the mobile communication devices in the CID of the first mobile communication device, the Location Information Service (LIS) for their respective current location.

14. An emergency communication apparatus comprising:

an emergency processing engine connectable to an Emergency Service Routing Proxy (ESRP) and/or a Public Safety Answering Point (PSAP), emergency processing engine configured to perform a method comprising:

obtaining location information of a location of a first mobile communication device that made an emergency call about an emergency incident

determining a Public Safety Answering Point (PSAP) that is in a vicinity of the location of the first mobile communication device,

forwarding the emergency call to the PSAP for being handled by a call taker at the PSAP,

upon receipt of location information of all mobile communication devices that are in the vicinity of the first mobile communication device, creating a list of all mobile communication devices that are in the vicinity of the first mobile communication device,

transmitting the list to the PSAP to be displayed at a display device of a call taker at the PSAP handling the emergency call, and

refreshing a map on which the emergency incident location and the mobile communication devices that are in the vicinity of the first mobile communication device included in the list are displayed based on updated location information of the communication devices located in the vicinity of the first communication device.

15. The emergency communication apparatus of claim 14 comprising the PSAP and the ESRP.

16. The emergency communication apparatus of claim 14 wherein the method also comprises displaying a map on which the emergency incident location and the mobile communication devices of the list of all mobile communication devices that are in the vicinity of the first mobile communication device are displayed.

17. The emergency communication apparatus of claim 14 , wherein the map also comprises indications of emergency facilities in the vicinity of the emergency incident location.

18. The emergency communication apparatus of claim 17 , wherein the method also comprises requesting a cell-ID (CID) of the first mobile communication device for identifying each base transceiver station (BTS) or sector of a BTS within a location area code (LAC).
