Abstract: Under the background of new infrastructure construction and computing and network convergence, the requirement of “cloud, network, edge and device” collaboration in ICT industry is enhanced. This paper analyzes the evolution trend of computing services, compares the technical architecture of the industry including the characteristics of distributed cloud and computing power network architecture, to propose a new concept of ubiquitous computing services as an evolution idea of computing and network convergence. It also introduces the key technologies involved in ubiquitous computing services.

Key words: ubiquitous computing, computing power network, distributed cloud
