The invention discloses a method and system for balancing a distributed load in an LTE (Long Term Evolution) access network, belonging to the technical field of wireless communication. The method comprises the following steps of: (S1) acquiring load information of a cell and an adjacent cell of the cell; (S2) judging loads of the cell and the adjacent cell, if the loads are judged to be normal loads, continuing to execute the step (S1), if the loads are judged to be overloads, executing the step (S3), and if the loads are judged to be high loads, executing the step (S4), wherein the overload state is that the loads are greater than or equal to a second threshold value; the high load state is that the loads are greater than or equal to a third threshold value and small than or equal to the second threshold value; and the normal load state is that the loads are smaller than the first threshold value; (S3) executing the load balancing process; and (S4) executing the load balancing preparation process. According to the method and the system, the load unbalance phenomenon in the network can be found in real time, and automatic distributed load balance can be realized.
