The present document disclosed an evaluation result reporting method and an evaluation result acquisition method, device and system. Herein, the evaluation result reporting method includes: UE performing an evaluation on a relation between throughputs of data transmission at a WLAN AP and a source serving cell (S402); and the UE reporting an evaluation result (S404). The present document solves the problem that a WLAN-side data flow offloading state and a situation of transmission experience of the UE cannot be obtained in a moving process of the UE in the related art. Thereby, the reasonable resource pre-configuration can be performed for the moving process of the UE, the resource allocation and utilization efficiency are improved, and the user experience is enhanced.
