Top Level Architecture

location based services

Java-based TLA enables different interfaces, as well as a variety of functions. Not only GPS or other beacon-enabled navigation, but also network-based, multimedia telecommunications and telematics, i.e., vehicle performance is one display window along with a well-prepared briefing about the next client.
Today Nokia and Siemens announced a merger of their communications service provider businesses into one network.
Siemens supports the CAN protocol for automotive control systems, along with a Java-based platform. In 2005 Siemens VDO Automotive, in conjunction with BMW, had enabled its TLA (Top Level Architecture) in the BMW 7, 6, and 5 series of cars to achieve what a reporter for the Sun Developer Network described as a “seamless addition and integration of location-based services, web services, and multimedia functionality throughout the vehicle’s entire life cycle.”
In a comprehensive article1 (August 4, 2005) about this automotive software platform, Steven Meloan noted that Siemens VDO was “actively seeking new development partners in the growing field of automotive telematics.”
“After the growth of the mobile phone,” says Krekels, “the car can become the new mobile device — where you can install everything from games to location-based services. And that’s why we’re looking for partners — to add their value in terms of content and creativity, and to establish businesses based upon this new mobile device.”
