1 Overview of Standardization of Next-Generation Mobile Systems 野田昭繁あらまし GPP 3rd Generation Partnership Project Release 8 Release 8 LTE Long Term Evolution EPS Evolved Packet SystemLTE HetNet 3GPP Abstract In 1998, standards bodies in Japan, Europe, North America, China and South Korea created the 3rd Generation Partnership Project (3GPP). Version 8 (called Release 8) of 3GPP was released in December 2008 as a set of specifications. This release formally specified Long Term Evolution (LTE), and also presented to the public new architecture for wireless networks and core networks, known as the Evolved Packet System (EPS). LTE supports packet communication services only and has a higher spectrum efficiency; thus, it has simpler architecture, higher data rates and ultra-low latency. However, the amount of data that networks have to cope with has increased in recent years with the increasing adoption of new devices such as smartphones, and it has become necessary to further expand system capacity. To find solutions to issues such as these, standardization activities including HetNet and centering on 3GPP have begun. This paper describes the future direction of these standardization activities for next-generation mobile communication systems, and the way Fujitsu s standardization activities are helping in this area.
