Abstract: Computing power network has become one of the significant methods to address the imbalance between computing power supply and demand by integrating multidimensional resources such as computing power, networks, and data. Meanwhile, with the rapid progress of terminal device technology, the ubiquitous terminal-side computing power has not yet been fully exploited. Based on the analysis of the enhancement of future pan terminal capabilities and the transition from passive to active, the architecture and functional features of Terminal-Side Computing Power Network are proposed. Targeting the characteristics of terminal devices, the main key technologies of Terminal-Side Computing Power Network are elaborated in detail, including perception of terminal behavior and computing power, computing power switching based on mobility prediction, service orchestration technology for differentiated terminal services, task deconstruction and computing power scheduling, trusted transactions between active terminals, etc. Through the study of a cloud-edge-end collaborative computing power network simulation environment, the enormous computing power potential of Terminal-Side Computing Power Network has been verified. Finally, the challenges faced by Terminal-Side Computing Power Network were analyzed, providing reference for the future development directions.
