The invention relates to a user level energy efficiency CoMP switching method based on an LTE-A system. The concept of user level is imported, an optimal cooperation set is selected for to-be-switchedusers of different levels to perform seamless switching. Compared with the traditional CoMP scheme, the scheme has the advantages that the personalized service requirements of the users of differentlevels can be met, because the users of high levels have high QoS requirements and are sensitive to delay in a communication process, so it is considered to preferentially select cooperation resourcesfor the users of high levels in a switching area when the resources are limited, thereby ensuring the communication quality of users of high levels and improving the switching success rate; and the users continuously measure the locations and the signal strength of mobile users in the movement process, and cooperation clusters are dynamically selected with the users as the center to meet the communication needs of the users. Switching users dynamically adjust the cooperation clusters of the high-level switching users in the movement process to meet the communication needs and to improve the switching efficiency; and in addition, from the perspective of energy efficiency, the cooperation cluster with the minimum power consumption is selected to improve the system energy efficiency while meeting the communication needs of the users.
