The invention provides a TD-LTE deep coverage blind compensation site selection method and system.. The LTE deep coverage blind compensation site selection method comprises the following steps: dividing an LTE cell to be subjected to blind compensation into a plurality of grids, and obtaining measurement report event class MRE data reported by a target sampling point in each grid; matching the MREdata reported by the target sampling point in each grid with a global system for mobile communication (GSM) work parameter table, and determining a GSM station corresponding to each grid; and grouping all the determined GSM stations according to frequency bands, sorting the GSM stations of each group according to a preset sorting rule, and taking the GSM station position at the top of the sortingof each group as the blind compensation station position of the blind compensation LTE cell. According to the TD-LTE deep coverage blind compensation site selection method and system, MRE data is used for reflecting the actual coverage condition of a user, compared with simulation calculation, the method and system are more accurate, the calculation process does not depend on manual field operation any more, and timeliness and economy are higher.
