The invention relates to the technical field of network security, in particular to a user location privacy protection method, system and equipment based on a confusion unloading strategy. In order to solve the technical problem of poor privacy protection of the position of a user side in the prior art, the method comprises the following steps: firstly, obtaining an initial unloading proportion by minimizing a resource consumption function; secondly, combining the fitting degree function of the initial unloading proportion with the differential privacy and the fitting degree function of the initial unloading proportion without the differential privacy with a confusion unloading proportion using probability function, constructing an unloading total revenue function, and obtaining the upper bound and the lower bound of the confusion unloading proportion by minimizing the unloading total revenue function value; and finally, based on the upper and lower bounds of the confusion unloading proportion and the initial
