This paper introduces several activities for standardization in the support of ubiquitous networking and energy saving in the next generation networks (NGN). For energy saving, we explain basic concepts of ubiquitous networking and present impact of services combing information technology (IT) and other industries using connected objects. Based on requirements for energy saving, we illustrate several examples such as smart home/building and intelligent transport system (ITS). Finally, we emphasize the necessity of developing valuable standards in collaboration with other standardization bodies for energy saving using NGN and connected objects
