Abstract: A system for derivation and provision of anonymised cellular mobile network data for population density and mobility report generation can be implemented on a computer, e.g. in a data warehouse system. The system includes effective anonymisation measures to protect the privacy of the mobile network customers. It comprises a load extractor and a database production environment, where the load extractor is connected with the mobile network to receive and anonymise traffic data from a mobile communications network, and where the production environment is set up to allow a third party to query the traffic data for the purpose of population density and mobility report generation. The production environment of the system presents itself as a “black box,” which can be operated by the third party only via specific interfaces. Thus, the system can be operated by a third party without compromising the privacy of the mobile network users.
