A method for acquiring quality of experience QOE of a telecommunication service is provided. The method includes: acquiring multiple groups of original KQI vectors and a QOE value corresponding to each group of original KQI vectors in the multiple groups of original KQI vectors; analyzing a relationship between the multiple groups of original KQI vectors and QOE values corresponding to the multiple groups of original KQI vectors to establish a function relationship between KQI vectors and QOE values corresponding to the KQI vectors; acquiring a current KQI vector, and applying the function relationship between the KQI vectors and the QOE values corresponding to the KQI vectors to obtain a current QOE value corresponding to the current KQI vector.
