ANNAPOLIS, MD, Oct 20 (MARKET WIRE) --
TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a world leader in
highly reliable and secure mobile communication technology, today
announced that the company has signed a five-year contract extension with
a Tier One U.S. wireless carrier to provide wireless E9-1-1 services
through August 2016. TCS will continue supporting the carrier's emergency
service needs to ensure that their wireless customers' distress calls are
routed to the appropriate Public Safety Answering Point (PSAP) together

maintains the required wireless E9-1-1 emergency services.

on top of the new technologies and mandates for emergency services can be
daunting," said Chris Nabinger, senior vice president of safety and
security for TCS. "We take pride in providing our customers with a fully

they expect, but does so in an affordable and easy-to-implement package."
