摘要

The present invention relates to a method of improving security in a communication network comprising a mobile device, a core network, a mobile packet core network and a wireless radio access network for access of the mobile device to the core network via the mobile packet core network. The method is characterized in that an identification of the mobile device (IMEI) is determined during connection setup of the mobile device (UE) via the wireless radio access network to the mobile packet core network. Furthermore an authentication entity of a mobile packet core network of a communication network is described.
