The present invention relates to a method for tracking a propagation path and generating a propagation model. 3D building information on the target area of the propagation model is read and a transmission point is established. A symmetric point for the building surface searched from the transmission point is found, and a 3D ray tube generated by reflected electromagnetic waves is generated. A 3D ray tube generated by the electromagnetic waves diffracted by the edge of the building surface searched by the transmission point is generated. The process for generating a 3D ray tube by reflection or diffraction for the building surface that is included in or crosses the area of the 3D ray tube generated by reflection or diffraction and is searched at the symmetric point or on the edge of the building surface is repeated, and the generated 3D ray tube is connected to the 3D ray tube. Therefore, the accurate propagation model is generated at the location for receiving the real electromagnetic waves.
