Services have become increasingly important in today's Web-based applications. Users can access services in an anytime, anywhere manner using a wide variety of mobile devices. Mobile services are a key driver in today's telecommunication market, even though the potential of mobile services has not been fully exploited in existing telecommunication systems. A main driver in these markets is context-aware services to build intuitive services for mobile handsets. One success factor is to support a broad range of handsets available on the market and making the services context-aware by obtaining contextual information. Context may be derived from information obtained from the handset - most prominently location information.
