Abstract
Emergency call localization is an important step in the emergency call taking process. As more than 80 % of emergency calls are dialled from mobile phones, the localization of calls in mobile networks deserves highest attention. In this paper we describe a model-based localization method which do not impose any special investments or modifications on the mobile network infrastructure. We create a model of the mobile network environment using the geographically referenced Self Organizing Map with interval values, trained on common measurements regularly performed by mobile network operator. Localization is then performed by finding the node of the model best matching to the characteristic vector of the call.
