To address the new paradigm of future services, cloud computing will be essential for integrating storage and computing functions with the network. As many new types of devices will be connected to networks in the future, it is very important to provide ubiquitous networking capabilities for "connecting to anything" between humans and objects for realize the Internet of Things (IoT). This paper introduces several challenges for the cloud computing in telecom perspectives and ubiquitous networking capabilities to support the IoT. For this, we present the basic concepts and present our vision related to this topic. In addition, we clearly identify characteristics and additional capabilities to support key technologies to be used for the IoT. For various services using ubiquitous networking of IoT, we propose the cloud-based IoT which aims to efficiently support varies services using cloud technology from different kinds of objects (e.g., devices, machines, etc). We also emphasize the necessity of virtualization for service evolution using smart environment of the cloud and the IoT
