In this paper, the authors first briefly review the collaborative communication technology, and indicate that current intra-system collaboration mainly focuses on collaboration of limited fields and cognition of some specific aspects, while inter-system collaboration has been simply used to provide access flexibility. This motivates the design of a more generalized framework: namely Collaborative HarmOnic Radio Ubiquitous network System (CHORUS). This framework is designed to achieve optimized performance gain and environmental friendliness by cognitive synergetics in the ubiquitous radio network environment. The idea of cognition is generalized by inspecting the status and parameters of multiple network scales and layers. Based on the cognitive result, harmonic control of collaborative and ubiquitous radio network systems can be applied to globally optimize the network performance.
