There is an increase in the use of mobile devices in business applications. However, mobile support services in such applications generally are usually not strongly integrated with business functions and mobility is often seen as an add-on capability. Consequently the use of mobile devices is often ad-hoc in nature and not closely integrated into the application. This paper describes a way to identify reusable services to support mobility in business applications. It emphasis that integration must support mobility within the application context and concentrates on setting up context sensitive communications in mobile environments.
