The invention provides a high-dynamic transformation method of a broadband special network of a high-speed train. The method comprises the following steps: setting a high-dynamic converter (HIDI) on a high-speed train; setting the high-dynamic converter on a train-ground communication mode in a coverage range of ground LTE (Long Term Evolution) base station (eNode) along the line of the high-speed train; and setting the high-dynamic converter on a train-satellite mode when no ground LTE (Long Term Evolution) base station (eNode) covers along the line of the high-speed train. The method provided in the invention combines the LTE technology, the satellite navigation technology and the satellite communication technology when the high-speed train moves at 300-500 km/h, so as to provide the broadband mobile communication, the network and the multi-media service for users in the train carriage and the other users moving at a high speed. 种高铁宽带专网高动态转换方法，在高铁列车上设置高动态转换器(HIDI)，在高铁列车沿线地面LTE基站(eNode)覆盖范围内，高动态转换器为车地通信模式，在高
