This paper analyzes and studies the influence of inaccurate decision of heterogeneous network switching algorithm on table tennis, and puts forward a heterogeneous network switching algorithm based on differential threshold ratio and improved grey association analysis. the algorithm uses the difference threshold ratio to pre-judge whether the network is switched or not, and then selects the target switching network through the improved grey association analysis algorithm to judge whether the network is switched or not. to test the performance of the algorithm, a heterogeneous network environment integrating WLAN and UMTS is established. MATLAB、OPNET and other simulation tools are used to compare the number of network switching and the failure rate of network switching. The results show that the algorithm reduces the number of network switching and the failure rate of network switching. The experimental results show that the algorithm can effectively improve the accuracy of network switching decisions and suppress the ping-pong effect..
