The fast development of communication technology and the increasing demand of the users result in the phenomenon that the load in the cell becomes more and more unbalanced.In this paper

we propose an algorithm based on load pre-allocation for Long Term Evolution（LTE）network to solve the problem.When a cell becomes overload

we select the optimal target cell through analytic hierarchy process method

which can reduce the ping-pong handover rate.Then we allocate the load in the overload cell according to the measurement of the load in the target cell.Finally

we adjust the cell individual offset to transfer the users to realize the inter cell load balancing.The simulation results show that the proposed algorithm can effectively improve the inter cell load balancing degree and the users’ experiences with smaller handover numbers.
