ENME: An ENriched MEdia application utilizing context for session mobility; Technical and human issues

Abstract

We look into the combination of a SIP application (IP based multimedia telephony) together with a context-aware smart environment. We start by describing a scenario where it is highly relevant to use such a combination. The combined application is called ENME, and is managing and moving communication sessions based on user context. We are realizing the service with SIP REFER and SIP extensions. We also discuss briefly other solutions such as 'virtual terminals', and we identify pros and cons of the different solutions. The application is implemented, and runs on a model railroad system, but the context model itself is more general. A next step would be to deploy the application in other smart environments, and we look briefly into a hospital environment. We end the paper by identifying some human issues for the service to work properly, and relate these issues to the technical solutions. © IFIP International Federation for Information Processing 2005.
