ClearTalk Selects TeleCommunication Systems-Hosted Commercial Mobile Alert System

ANNAPOLIS, MD, Sep 13 (MARKET WIRE) --
TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a world leader in
highly reliable and secure mobile communication technology, today
announced that Lubbock, TX-based ClearTalk Wireless has selected the
TCS-hosted Commercial Mobile Alert System (CMAS) service to meet the
Federal Communications Commission's (FCC) April 2012 deadline for
providing subscribers with automatic alerts in times of crisis. The
Federal Emergency Management Agency's (FEMA) Personal Localized Alerting
Network (PLAN), based upon the Commercial Mobile Alert System
specification, is a new public safety system that allows customers who
own an enabled mobile device to receive geographically targeted messages
alerting them of imminent threats to safety (e.g., earthquakes,
hurricanes, etc.) in their current location. The FCC issued the 2012
mandate to create a life-saving service that will allow FEMA to deliver
timely and accurate emergency alerts and warnings to the cell phones of
citizens in targeted geographical areas.

The FCC proposed and adopted the network structure, operational
procedures and technical requirements in 2007 and 2008 in response to the
Warning, Alert, and Response Network (WARN) Act passed by Congress in
2006. The TCS location-based emergency alert messaging capability not
only helps ClearTalk Wireless to comply with the WARN Act, but also
enables commercial message broadcasts of geographically relevant
information, such as enterprise notifications, traffic, news, and
coupons. ClearTalk Wireless will receive all aspects of the TCS CMAS
service, including system design, integration, testing, deployment and
the use of TCS' proven public safety platform and TL-9000 certified
facilities.

"As a leading regional wireless carrier, ClearTalk Wireless is
proactively adopting cutting-edge hosted technology to meet the FCC's
requirements," said Mark Titus, vice president of carrier software at
TCS. "While it is not mandatory to offer CMAS service, ClearTalk Wireless
is committed to inform and protect their wireless customers from imminent
danger as part of their service. The real benefit of this service is that
it is going to be there as another form of emergency communication. The
service is going to be tied to a specific geographic area of interest, so
it will alert only those individuals in the path of danger and provide
instructions on how to recover once the danger has passed."

CMAS is intended to provide federal, state and local governmental
agencies a means to send alerts and warnings to the public. Specifically,
CMAS provides officials the ability to send 90-character, geographically
targeted messages to the public regarding presidential emergency alerts,
AMBER Alerts, and warnings of imminent and local threats to life and
property, such as natural and man-made disasters. As the leading
U.S.-based technology provider for text messaging, public safety and
location solutions, TCS powered the delivery of nearly one trillion text
messages and half of all wireless 9-1-1 calls in 2010 alone.

With the nation's only non-carrier TL 9000-certified network operations
center (NOC), as well as extensive provision of E9-1-1, text messaging,
and location-based services, TCS possesses the experience and technical
capabilities necessary to position carrier customers to meet the FCC's
CMAS requirements. For additional information on TCS' CMAS solution,
