In this work several methods for the location of legacy GSM handsets are compared. These methods use data available in the mobile station measurement report - communication channel server identity, received power levels from the serving and neighbor cells, received signal quality - and time alignment with the server. It is discussed how these parameters can be used for mobile station positioning. A new approach for the cell identity plus time alignment method, using propagation modeling, is proposed. The efficiency of radio-frequency fingerprint correlation using coverage prediction maps of different resolutions is also analyzed. Field tests were conducted to evaluate the methods in real scenarios.
