The invention discloses a distributed user access method, and belongs to the technical field of wireless access networks. The distributed user access method comprises the following steps: firstly, each to-be-accessed user separately performs non-cooperative performance evaluation with accessable nodes to determine a potential user type; then, the user performs initial access, and calculates a rate gain and a necessary cost; the above information is broadcasted to F-AP nodes in the vicinity; and finally, each F-AP node calculates a utility function and an average utility function of each user according to the broadcasted information, performs iteration on the access selection of each user, and performs fine tuning switch on the communication mode. According to the distributed user access method disclosed by the invention, in view of high transmission delay, limited Fronthaul capacity and other problems of the traditional user access method, the influence of the transmission rate and the delay are comprehensively considered by making full use of the storage ability and the data processing ability of a network edge device; and the compromise between the own performance of the user and the overall performance of the network can be quickly achieved, the limited trip link capacity is greatly relieved, the data transmission delay is shortened, and the user experience is improved.
