TeleCommunication Systems and OpenTable Partner to Deliver OpenTable for Mobile Web

  CTIA -- Booth # 8706 --  TeleCommunication Systems, Inc. (TCS)
(NASDAQ: TSYS), a leader in wireless location infrastructure and
applications, today announced its relationship with OpenTable, Inc., the leading provider
of free, real-time online restaurant reservations, to empower its mobile
users with enhanced wireless reservation capabilities, including additional
customized services and the synchronization between mobile and computer
reservation services.

Working with OpenTable, TCS developed OpenTable for Mobile Web utilizing wireless application protocol or WAP so that customers can look up restaurants, check availability, and book or cancel reservations through their mobile devices. Now, through TCS' technology, OpenTable for Mobile Web users benefit from a seamless integration between desktop and mobile services, permitting users for the first time to view changes made from their computers on their mobile devices and vice versa.

"Because of its long history and success in creating and delivering wireless and location services, TCS was the ideal partner to help design the OpenTable for Mobile Web service and bring the convenience of our online reservation services to the mobile user," said Mike Xenakis, OpenTable's senior vice president of product management. "Now, mobile users can take the power of OpenTable.com with them wherever they go, to instantly find and book available tables at more than 10,000 restaurants."

The service is hosted and integrated with TCS' leading Xypoint® Mapping Server, allowing users to quickly and easily select restaurants and make reservations based on their exact location. Xypoint Mapping Server, a location-based services platform, enables the development and deployment of location services within new and existing applications. Supporting Web, mobile and on-board clients, Xypoint Mapping Server provides a technology platform for client applications to request and receive location, routing and point-of-interest information, as well as generate maps and directions.

"As consumers continue to become more reliant on their mobile devices, wireless applications are becoming crucial to the success of many businesses," said Drew Morin, Senior VP, Chief Technology Officer, TCS. "We take pride in providing industry leading wireless and location-based services that meet the unique and often mission critical needs of our customers. Through this relationship, OpenTable is expanding the flexibility and functionality of OpenTable reservation services, improving ease-of-use and accessibility, regardless of location."

The OpenTable mobile site is designed to mimic the simple, streamlined reservation process offered on OpenTable.com, allowing users to quickly identify restaurants with available tables and narrow their choices by neighborhood and desired times. OpenTable Mobile for Web is currently available to book reservations at all OpenTable restaurants in the United States. In order to take advantage of OpenTable Mobile for Web, users must have a Web-enabled mobile device and subscribe to a data plan with their carrier. OpenTable does not charge users to access the site or book restaurant reservations; however, standard data and text messaging charges from users' mobile carriers may apply.
