ANNAPOLIS, Md. -- TeleCommunication Systems, Inc. (TCS) (NASDAQ:TSYS), a global leader in wireless data technology, announced today that Cricket Communications, Inc., a leading provider of unlimited local and domestic long distance wireless services, has signed a multi-year contract extension with TCS to continue delivery of life-saving E9-1-1 services to Cricket's customers in 39 U.S. markets across 20 states.

"TCS' E9-1-1 service is a proven and reliable solution for providing Public Safety Answering Points (PSAPs) with the precise location of our wireless subscribers when dialing 9-1-1," said Glenn Umetsu, Executive Vice President and COO of Cricket.

TCS' E9-1-1 solution enables wireless carriers to comply with Phase I and Phase II of the FCC's mandate, while providing the life-saving emergency services and security that wireless consumers expect.

In addition to its proprietary technology platform, TCS provides carriers with end-to-end support and all aspects of deployment, from switch integration, database management and Geographic Information Services (GIS) to compliance expertise and cost-recovery assistance.

"TCS' Xypoint(R) Location Platform and Position Determining Entity (PDE) services allow us to provide wireless location services to our customers with confidence in a timely, seamless and comprehensive delivery," said Chris Demange, Cricket's Director of New Technology.

"TCS brings a depth of expertise with carrier network engineering and software, enabling us to solve complex problems that invariably arise in deployment environments. This, together with our industry knowledge and regulatory compliance expertise, enables us to address complex E9-1-1 issues to maintain our carrier customer subscribers' safety. We are pleased that Cricket has reaffirmed TCS as their provider for E9-1-1 services," said Robert Dawson, Senior Vice President of Service Bureau Operations for TCS.
