Evaluating the cel performance indicators of LTE and dividing them into two classes:ordinal and reversed ones. It builds the in-dicators’key values and the corresponding switching hysteresis thresholds,thus a correlation between the indicator and hys-teresis was established. Based on this correlation,it gave an intel igent judgment model,and then proposed a new LTE hand-off algorithm based on the intel igent judgment (IJHA). IJHA can automatical y calculate the cel ’s performance indicators and improve the cel ’s ability while keeping the subscribers’feeling level. Comparing with the traditional A3 algorithm,IJHA can reduce the ping-pong switching times and lower the serving cel ’s load. Final y,it uses matlab to build a simulation platform, test the performance of IJHA,including its efficiency and performance.%评估LTE小区的性能指标，根据影响效果分为顺势和逆势指标。设定指标临界值和对应的切换迟滞门限，从而建立相对应的切换迟滞关联。基于关联，建立了智能判决模型，在模型的基础上提出了基于智能判决的LTE切换算法。该算法能够自动衡量目标服务小区的性能，在不牺牲用户感知的前提下，大幅提升小区的吞吐能力。与传统的LTE切换算法相比，该算法能够在减少乒乓切换的同时进一步降低服务小区的负载。最后，通过Matlab搭建了一个仿真平台，验证该算法的效果和性能。
