TCS Enhances Short Message Service Center Solution With Location-Based Messaging Services

Market Wire, March, 2008

CTIA - Booth # 1341 - TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a leading provider of mission-critical wireless communications, today announced that the company has enhanced its Short Message Service Center (SMSC) solution to enable wireless carriers to deliver next-generation, location-based messaging services to their subscribers. Key new features that work in concert with one another include Short Message Service ( SMS ) banners, Location-Based Service ( LBS ) support, and enhanced anti-spam capability.

SMS Banners: On average, most wireless subscribers do not use the entire character payload when sending an SMS message, leaving available screen space. TCS now offers wireless carriers the ability to use the leftover payload for simple SMS banner advertisements, similar to the banners found on Internet e-mail accounts. Any wireless carrier can now establish co-marketing agreements with organizations seeking direct marketing channels via mobile devices to consumers. According to a March 2008 report from The Nielsen Company, the number of mobile phone users who recalled viewing mobile advertisements in 2007 rose by 38 percent to 58 million in the fourth quarter, compared with 42 million in the second quarter. This solution provides an important entry point for mobile advertising while allowing the wireless carrier to provide opt-in geographically targeted and advertising-subsidized text messaging to their subscribers that builds upon the text messaging craze that continues to sweep the country. According to CTIA statistics, US wireless subscribers sent over 300 billion text messages in 2007 -- almost double the number sent in 2006. TCS' SMSC technology was responsible for delivering over 25% of these messages.

Privacy and anti-spam: As an advocate for the use of precise location by wireless carriers, TCS has long been a proponent of strong privacy protections for the wireless subscriber. With the growth of mobile advertising also comes the potential increase of spam on mobile handsets. TCS SMSC now offers mobile spam protection. Subscribers who do not want to receive advertisements will now have the ability to block or opt-out from receiving future ads following receipt from selected sources. The subscriber can forward the unwanted advertisement or message to an SMS shortcode number. The TCS SMSC then blocks any future messages from that source to that specific handset.

"TCS recently celebrated ten years as a market leader with our SMSC solution, and we are committed to the continued support of our wireless carrier customers with the development of next-generation text messaging solutions," said Timothy Lorello, Chief Marketing Officer of TCS. "We are rapidly evolving our core text messaging offering to answer the carriers' demands for new location-based services that provide additional means to generate revenue, and we have found ways to take our trusted role in the wireless network to offer privacy enhancements and mobile anti-spam capabilities to further protect consumers."
