The present invention discloses a user behavior recognition method, a user equipment, a behavior recognition server, and a behavior recognition system, where the method includes: acquiring, by a first user equipment, statistical distribution information of a target parameter corresponding to a target user behavior, where the target parameter includes at least one parameter in a behavior recognition model of the target user behavior, and the statistical distribution information of the target parameter is determined according to values of the target parameter in behavior recognition models of the target user behavior that are respectively corresponding to multiple other user equipments; and creating and saving, by the first user equipment according to the statistical distribution information of the target parameter, a behavior recognition model of the target user behavior that is corresponding to the first user equipment, to recognize the target user behavior. According to the user behavior recognition method i
