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

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.

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.
