Abstract: With the rapid development of the Information & Communication Technology（ICT） and the popularity of Internet applications, wireless communication networks are with the tendency of dense deployment, high energy consumptions and carbon emission problems. It has caught huge impact on environment. The user associated base station switching on-off strategy can effectively reduce energy consumptions. The existing strategies mainly focus on Quality of Service（QoS） for users, while not fully considering the influence of user experience for specific applications. This paper proposes base station Energy Saving strategy oriented toward Multi-Service User Experience（ES-MSUE）. Nonlinear integer programming is utilized to model the above problem, which achieves the tradeoff between user experience and energy consumption. By comparing with other relative energy saving strategy, the results show that ES-MSUE achieves better performance on user experience and energy savings.
