Context Information in Mobile Telephony

Most research in context-aware computing offers definitions of context that consist solely of measurable information. Using mobile telephony as an example of a computing area, we provide a set of context information relevant to the area drawn from a qualitative case study: identity, location, time and present activity. After arguing that these context measures are not the same for other areas of computing, three guidelines for designing context-aware features for mobile telephony are provided. We conclude that context information should be defined for the area in which the researcher is present instead of attempting to provide an overall definition of context.
