TeleCommunication Systems, Inc. Issued U.S. Patent on Interactive Menus for Mobile Devices Using Short Messaging Services

Wednesday, December 30, 2009

Annapolis, MD -- TeleCommunication Systems, Inc. (TCS) (Nasdaq: TSYS), a leading provider of mission-critical wireless communications, today announced the issuance by the U.S. Patent and Trademark Office of patent number 7,640,031 entitled "Mobile Originated Interactive Menus Via Short Messaging Services."

TCS patent number 7,640,031 describes a two-way interactive short message system (SMS) that provides personalized messaging menus to a handset. Unlike browser-based menu systems for mobile devices, this invention enables mobile originated interactive menus using SMS communications instead of circuit switched data (e.g., instead of Wireless Application Protocol (WAP) communications), thus leaving traffic channels available for voice calls. Moreover, mobile-originated mobile devices are less costly than are WAP or Wireless Local Area Network (LAN) equipped mobile devices, thus allowing mobile carriers to offer service providers a larger customer base, and subscribers less expensive options to access wireless services.

Mobile originated interactive menus as described in this patent provide several advantages to the wireless carriers, service providers and mobile device users. These interactive SMS menus may be implemented as a feature of a Short Message Service Center (SMSC) that allows service providers to configure several levels of menus with multiple options per menu. Each option guides the user to either the next menu level, or to a final action to be executed according to the path followed by the subscriber. The flexibility of interactive SMS menus allows service providers to define their own base offering of menus, depending upon their targeted customer segments.

On the handset user side, users may define the content and frequency they want, whether it is a scheduled delivery or on-demand. The interactive SMS menu options offer customers a simple-to-use technique and apparatus for checking stock quotes, local weather, and/or other Web-based news and information when they want it. The interactive nature of the service allows the wireless network to poll the user for their next response, with multiple menu options offered, making it highly intuitive. Replacement of messages in TDMA and GSM mobile devices allow for heavy usage without filling up the user's phone buffer by allowing prior messages to be overwritten. This assures that only the latest information is all that is being displayed and read.

"Enabling wireless carriers to offer a robust, bandwidth efficient and less expensive alternative to browser-based interactive menus gives those carriers a competitive edge," said Drew Morin, chief technology officer of TCS. "This invention also demonstrates how innovative thinking can take an established technology like SMS and stretch its boundaries to provide new solutions."

TCS now holds 108 patents with over 300 applications pending.
