Internet protocol based 911 system
| Details |
Inventors: Cleghorn, Monica;

Primary Examiner: Phan; Dao

Attorney, Agent or Firm: RG & Associates
The present invention provides a system, method and apparatus for initiating and handling an emergency IP request using an IP enabled device having GPS capability. The IP enabled device is monitored for one or more emergency criteria. If the emergency criteria are satisfied, global positioning data is obtained using the GPS capability and the emergency IP request is sent to an address server. The address server receives the emergency IP request, obtains local emergency services data based on the global positioning data, dials a call center station based on the local emergency services data and passes an emergency call from the IP enabled device to the call center station. This invention can be implemented as a computer program embedded in a computer readable medium wherein the steps are performed by one or more code segments. |

DETAILED DESCRIPTION The present invention provides software applications that communicate with Global Positioning Systems ("GPS") hardware embedded in Internet Protocol ("IP") enabled equipment such that when the equipment is used to access emergency services by entering 911 or pressing an emergency activation button, the software provides the means to determine the location of the calling equipment to the respective emergency service center appropriate to the location of the emergency.
More specifically, the software monitors the voice over IP ("VoIP") software installed on the IP enabled equipment.
When 911 is entered, the software acquires the vertical and horizontal coordinates ("V&H") from the GPS hardware, overrides the installed VoIP software to send a Session Initiation Protocol ("SIP") request to an address server which is also monitoring the Internet for these specific sessions.
The address server accepts the SIP from the originating hardware, receives the V&H and accesses a database that cross references emergency services direct dial numbers with the V&H.
The address server passes the voice call and the available direct dial numbers to a call center that handles emergency voice interface with the person who entered 911 at the originating equipment.
The call center operator chooses which emergency service to dial after speaking with the person who has the emergency, or defaults to the fire rescue number.
The present invention is applicable to both wireline and IP telephony systems, such as laptop computers, PDAs, etc.
The present invention does not rely on a set IP address, so that it will work on virtual networks and with transactional IP addresses.
GPS coordinates are cross referenced to the closest physical emergency services.
For example, the system may provide four or more numbers to the operator (police, fire, poison control, emergency medical services, rescue, etc.
).
The operator selects the appropriate number and routes the call via the Public Switched Telephone Network ("PSTN") or directly to the IP address
