Socially enhanced reachability support within an IMS-community-based infrastructure solution Krifka Dobes, Zuzana; Lüke, Karl-Heinz; Rederer, Andreas Erfurth, Christian; Eichler, Gerald; Schau, Volkmar At Deutsche Telekom Laboratories we are investigating how group communication can be enhanced with contextual information such as reachability. We demonstrate these methods using a group communication scenario which is of interest to us from a user and telco perspective. The scenario includes features such as messaging, presence and „click-to“ style communication, including conferencing between friends and persons with common interests. We summarize our analysis of two types of approaches to the next generation IMS platform capabilities, modular and layered approaches. We include lessons learned from our prototypes efforts, which made use of IMS capabilities. We point out some of the technical challenges that were confronted while realizing a showcase of use cases involving groups communication involving users using mobile devices and as well as users connected by web on their home PCs.

Towards internet communities to help improve the wellbeing andrehabilitation of clinically stable chronic patients Wienhofen, Leendert W. M.; Svagård, Ingrid Erfurth, Christian; Eichler, Gerald; Schau, Volkmar The EU project NEXES introduces IT support for integrated healthcare, and attempts to prove through clinical trials how new technology can help improve healthcare. The web-based approach used in the Norwegian clinical trial on wellbeing for chronically ill patients can be seen as a very small health care community for the patients. After introducing the NEXES project, the technical platform used for the wellbeing case, and the collaboration notation in BPMN, a specific case is described in detail and related to how the collaboration between the patient and health care stakeholders can be seen as a small group. Finally reflections are given on how the clinical trial could be extended by adding a 'competition' element using online communities in order to motivate the patients to do their rehabilitation exercises, and which technology standard could be used for this approach.

Integrated solutions and services in public transport on mobile devices Lüke, Karl-Heinz; Mügge, Holger; Eisemann, Matthias; Telschow, Anke Erfurth, Christian; Eichler, Gerald; Schau, Volkmar Our society is characterised by individuality, comfort and mobility. It has been shown in many scientific studies that the mobile phone plays an important role in our living and working environment. While navigation systems in cars offer a high level of individuality, comfort and a high degree of integration with the car electronics, there are no comparable solutions and services available in public transport. In this paper, it is described that integrated solutions in public transport can improve the user needs in terms of flexibility and convenience. Although there are several individual mobile applications for rail information and ticketing available, an integrated and profile-based solution is hard to find on the market. We propose an integrative architecture that covers mobile trip planning, intelligent mobile ticketing and community solutions during the trip. This shows that our findings can enhance flexibility and comfort in public transport.
