Nowadays, accessing emergency services and customer healthcare, in Spain, is done only by traditional phone calls to the number 061. In order to facilitate interaction between the emergency users and the emergency service system, we are improving and expanding new channels of personal communication. Given that the use of smart mobile devices is widespread in our society, we are developing a mobile application for emergency management, providing the same assistance as phone calls and adding some brand new features. We have developed requirements design and a functional specification of our new mobile application aimed at improving user interaction with the traditional emergency systems. The functionalities of the Web application are focused on providing a direct communication service, complete and effective, allowing quick and accurate intervention of the emergency services. Our purpose is to define a platform fully accessible to all users, regardless of their language and/or technological knowledge. Thus, the focus of this paper is mainly devoted to explain how to extend traditional applications based on emergency phone calls, to modern mobile applications considering not only web technologies, but also social networking behavior.
