摘要

The future wireless telecommunication environ ment is characterized by the co-existence of a multitude of wireless networks such as LTE, LTE-Advanced, UMTS, WiMAX, WiFi etc. In order to be able to offer the best connectivity, according to the requirements of the users and to the preferences of the operator, a novel functionality was introduced in the core network and in the mobile devices for access network discovery and selection. This paper introduces this functionality as standardized in the 3 GPP Evolved Packet Core (EPC), highlighting its main concepts and technical scenarios. Further, a set of novel optimizations are presented and evaluated, followed by the description of their implemen tation as part of the Fraunhofer FOKUS OpenEPC toolkit.
