TCS Provides Innovative Solutions to VoIP E9-1-1 Location and Call Routing Challenges

A Unique TCS Feature Delivers a Frequently Requested Service to Assist Public Safety to Route and Deliver Emergency VoIP Calls

ANNAPOLIS, MD -- (MARKET WIRE) -- August 28, 2006 -- TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a leading provider of mission-critical wireless data solutions and a leading nomadic VoIP Positioning Center (VPC), is enhancing the location and call routing of Voice over Internet Protocol (VoIP) Emergency 9-1-1 with its array of pioneering services.

"TCS continues to lead through innovation and holds over 20 patents and pending patents in this area," said Dan Allen, Senior Vice President for Service Bureau Operations for TCS. "Real-time MSAG validation demonstrates this expertise. By focusing on the more difficult needs of the nomadic user, TCS has developed a MSAG solution that exceeds the needs of the static-user market."

TCS' foresight and product innovation provides industry-leading VoIP E9-1-1 service to nearly 2 million VoIP users and to over 3,500 Public Safety Answering Points (PSAPs). TCS specialized services include:

--  Delivery of the Master Street Address Guide (MSAG) address -- With its
    advanced MSAG matching engine, TCS compares customers' civic addresses to
    the MSAG and delivers the MSAG version of the address to the PSAP. This
    assures the address presented to the dispatcher is compatible with existing
    systems. TCS' VPC delivers the civic address in the event the address
    cannot be MSAG-validated, a feature unique to TCS and frequently requested
    by PSAPs.
--  MSAG-based routing -- TCS is now able to use the MSAG to determine the
    proper Emergency Services Number (ESN) information for individual calls and
    to assign Emergency Service Query Keys (ESQKs) for routing per the ESN.
    This eliminates the requirement for ESN and significantly reduces the
    PSAP's challenge of developing and maintaining Geographical Information
    System (GIS) shape files for each ESN.
--  Multi-ESN deployments -- TCS has pioneered the deployment of nomadic
    VoIP service at the ESN level.  PSAPs prefer ESN-level deployments because
    they preserve the correct responders in the English Language Translation
    (ELT) data and because they retain the selective transfer function. TCS'
    MSAG-based routing capability eliminates the GIS component of these
    deployments, which remains a major barrier for most VPCs.
--  MSAG Validation for static VoIP addresses -- TCS has demonstrated
    significantly higher automatic MSAG matching rates than other solutions;
    this improves customers' ability to activate service for the end-consumer
    and reduces the cost of resorting to manual alternatives.  This real-time
    validation function facilitates the uploading of static Automatic Location
    Information (ALI) addresses by performing a preliminary MSAG validation.
--  Rapid E9-1-1 Deployments -- In less than a year, TCS has deployed VoIP
    E9-1-1 to over 3,500 PSAPs across the country.

In addition, in its proven wireless E9-1-1 solution, TCS now allows PSAPs that are using PSAP to ALI Message (PAM) and (legacy) NENA ALIs to overcome limitations in these protocols that inhibit the delivery of Mid-Call Location Updates (MCLUs). With this feature, PSAPs can obtain MCLUs when they are available without requiring changes to the legacy emergency services network.
