It is expected that the emergence of new service scenarios driven by user needs beyond 2020 will be different from today. But current 4G LTE (Long Term Evolution) network is not enough to fulfill arising new requirements because of fundamental problems in Evolved Packet Core (EPC), including centralized routing mechanism. In this regard, 5G mobile network architecture needs to be redesigned to solve the problems of EPC. In this paper, we present revolutionary direction for the architecture of 5G mobile core network to meet the requirements of the new services which are described in IMT (International Mobile Telecommunications) 2020 vision. In addition we propose a reference model and key mechanisms to implement those proposed directions for 5G mobile core network.
