With the wide spread use of cellular phones and the increased interests in the well-being of people, many vendors of cellular phones start to embed a variety of u-health services in their cellular phones. While the u-health services look different from the service``s point of view, they share many common features at various levels such as service structure, unit service, and data levels. Thus, it is ideal to develop u-health services on a common framework using the common features and services in the framework rather than developing u-health services independently or separately. In this paper, we propose an u-health framework on which u-health services can be systematically developed by utilizing functions and features, and following guidelines provided by the framework. Common features and services that can be shared among u-health services are extracted, registered, and manipulated in the framework. The proposed framework will have strength in the aspects of service flexibility, accessibility, evolvability, reusability, adaptability, interoperability and guideline provision in developing u-health services.
