Context-Aware Emergency Notification Service over 4G EPC Network: Concept and Design

In this paper we present the concept of context- aware Emergency Notification and Rescue Service (ENRS) utilizing user information from the 4G EPC network. The 4G EPC is an all IP next generation architecture that makes it easy for various 3GPP and non-3GPP standards to co-exist and provide network access to the end user. The proposed architecture consists of two parts; first part is emergency notification and information gathering to use for the event notification. The second part consists of an intelligent context-aware decision engine that processes the collected information in real time and generates notification messages for the end user. Our proposed service is based on the RESTful concepts and can be used to effectively notify and help users during the emergency. Currently a prototype of the service is being developed to validate the ENRS.
