JRC has developed LTE Core Network System which consist of 2 major devices of both EPC（Evolved Packet Core） device and LTE Network Management System called EMS（Element Management System），in order to realize Compact LTE system for small and middle class communication operators. EPC supports standards features and interfaces comply with 3GPP LTE Release 9 in one box, and is installable on universal OS（operating system）and general hardware platform such as ATCA（Advanced Telecommunications Computing Architecture）server. Also, JRC EPC offers easy to operate GUI to enable easy configuration, for fast operation. Therefore JRC’ s EPC enables to fast entry of new LTE networks with minimum CAPEX/OPEX. EMS enables total management of installation, configuration, operation, and maintenance for LTE network devices such as eNodeB（Evolved Node B），EPC, and other network elements.
