Mobile telephony has become a commonplace of modern life. Mobile computing is less well established, partly because of the lack of a common standard infrastructure. With the increasing number of mobile workers, a secure mobile architecture (SMA) is needed to allow individuals to maintain connections when away from their fixed workplace location.

Secure Mobile Architecture (SMA) grew from work in The Open Group Mobile Management Forum (MMF). The MMF developed a demonstration of seamless session management across different networks, which was given at The Open Group Conference in Berlin, April 2001. This led to the development by the MMF together with The Open Group Directory Interoperability Forum (DIF) of the Business Scenario – The Executive on the Move – that described the requirements for directories to support mobile computing. The Open Group then worked on a Challenge to vendors of directories and related products to provide support for mobile computing.

The architecture described in the SMA Vision and Architecture was developed by the Challenge team. Its central feature is the use of directory technology to make information about users and the network available to applications, management systems, and intelligent network components. A directory schema appropriate for this purpose was developed and worked out in detail.
