TCS Awarded Patent for Web Browsing Over Non-IP Based Networks

Patent Discloses Optimized Method for Wireless Device Interface With the Web

TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a leading provider of mission critical wireless communications, today announced it has been awarded a patent by the United States Patent and Trademark Office for its proprietary system and method for controlling wireless devices' interface with the Internet. The patent is titled System and Method for Re-Directing Requests from Browsers for Communication over Non-IP Based Networks. This specialized invention enables a wireless device equipped with a standard browser to communicate with the Internet efficiently via a non-Internet Protocol (IP) network. This approach can reduce the user's transmission costs as well as increase the perceived bandwidth of the network.

U.S. Patent No. 7,003,571 acknowledges TCS' originality in optimizing communications over non-IP networks to save bandwidth by using a connectionless send and receive mechanism. This invention eliminates the high bandwidth requirements inherently associated with HTTP communications for wireless connection to the Internet, enabling more users to have fast access to the Web. Additional performance enhancements are achieved from the connectionless environment through the use of message segmentation and reassembly, message retries, and message acknowledgements.

"TCS' leadership in developing this advanced technology in the wireless arena enables carriers to offer a fast and cost effective browsing experience to their subscribers," said Maurice B. Tose, Chairman, President and CEO of TeleCommunication Systems. "The invention improves the performance of the user's web browsing experience and is useful whenever bandwidth limitations or efficiency is desired in wireless or wireline networks."

TCS now holds 41 patents and has over 100 additional patent applications pending in the United States and jurisdictions throughout the world.
