Measurement report (MR) base methods are a kind of cell identifier (CI) base methods whose parameters could be extracted from MRs and the cell configuration database (CCD). They are utilized for location based services (LBS), and take advantages in wireless network optimization. In this paper, we suggest the enhancements of virtual antenna method which is the improvement of enhanced CI-RXLEV method. We divide the location procedure into 2 steps, the first step is the virtual antenna method, and the second step utilizes the results calculated by the first step for filtering cells. So the cells which are far from the UE and nearby the serving cell could be filtered more precisely. We also improved the MPPE criterion cited by the virtual antenna. A new parameter is imported to avoiding MPPE score approaching zero. The experiment results show that our new enhancements perform better than the original virtual antenna method, and the position accuracy is close to the fingerprints.
