The world of LTE is enshrouded in acronym soup, mystery, and technical documents that implement security by obscurity. In this talk, we will shed light on the magic that is the evolved packet core, otherwise known as the EPC. The EPC is the packet routing engine that connects the tower to the Internet. We will discuss the network communication protocols, core infrastructure elements, and basic architecture of this system. In closing, we will disclose successful crashes and kills that we have had in this network and discuss the potential for large scale communication disruption.
