TCS Issued Patent for Enhanced E9-1-1 Location Information Using Voice Over Internet Protocol15 September 2005
TeleCommunication Systems, Inc. (TCS)
(NASDAQ: TSYS), a global leader in mission critical communications, today
announced that the U.S. Patent and Trademark Office has issued patent
number USP 6,940,950, titled "Enhanced E9-1-1 Location Information Using
Voice-over-Internet Protocol (VoIP)." TCS now holds 38 patents and has
approximately 100 additional patent applications pending in the United
States and jurisdictions throughout the world.
The patent covers an E9-1-1 Voice-over-Internet Protocol (VolP) solution
wherein a 911 call from a VoIP device is routed directly to the correct
Public Safety Answering Point (PSAP) via dedicated trunks. The voice call
is delivered to the PSAP along with the caller's correct location, and
callback number.
The patent provides a means for querying a Message Servicing Center (MSC)
from a VoIP switch and a means for receiving an Emergency Services Routing
Key (ESRK) in response. Additionally, the patent allows querying by an
Automatic Location Identification (ALI) database for caller information
related to the ESRK.
VolP gateways are implemented locally, at least one per Local Access and
Transport Area (LATA) and accept inbound VolP packetized data. The
packetized data is then converted to a standard wire line voice call format
calls. Calls are routed to an Internet Protocol (IP) address at the VoIP
gateway. The gateway egresses the call to a voice port at a selective
router. Dedicated voice trunks connect between each local VoIP gateway to
appropriate selective routers. An Automatic Location Identification (ALl)
database is provisioned with ESRKs dedicated for VoIP use. Transmission
Control Protocol/Internet Protocol (TCP/IP) circuits may be established
between some or all of the various local VolP gateways.
Maurice B. Tosé, Chairman, President and CEO of TeleCommunication Systems
stated, "Implementing the technology covered by this latest TCS patent is
very important to the widespread adoption of VoIP. When emergency services
are readily accessible via wireless VoIP devices, the barriers for mass
VoIP adoption begin to relax and the needs of public safety are addressed
more adequately."
