With the construction and application of LTE

TD-LTE has become feeble to meet the growing business needs of users in terms of capacity and depth coverage due to the frequency characteristics and the ratio of upper and lower time slots. In this case

TF collaborative optimization has received much attentions for capacity diversion and promoting user perception. Due to the difference of various scenes

personalized strategies is badly needed for formulating the TF collaborative optimization of the specific scenario. As the gateway and image window of the city

the network quality of the airport expressway has always been the focus of the operators’ optimization work. Based on the high-speed airport scene of a city

this paper discusses the realization principle and optimization scheme of TF collaborative optimization

providing ideas for solving the problems of important scenes like excessive load

poor user experience perception

insufficient depth coverage

etc.
