The dynamic changing context of the user poses unique challenges even on the advanced network and communication system. The system becomes more demanding especially when it has to facilitate appropriate and instantaneous services in emergency medical and health care situation. This paper presents a novel mechanism that integrates context awareness with pervasive computing in healthcare services to meet the dynamic needs of patient precisely. The proposed study uses higher dimensionality in the context design for encapsulating the precise clinical and non-clinical condition of the ill-individual and design a framework based on pervasive computing and Ambient Intelligence for catering up the emergency need using IEEE 802.15 standard and 3G based mobile network. Supported by real time experiments using heterogeneous sensors and accelerometer, the results shows better and effective performance of the system.
