Abstract: Methods and apparatuses for managing wireless signal information for positioning a mobile terminal are provided. The wireless signal information obtained by measuring a signal characteristic with respect to access points of a target area, is stored in a database. At least one piece of position error information calculated based on the wireless signal information is received from at least one mobile terminal. A positioning reliability is assessed with respect to the target area, based on the at least one piece of position error information. It is determined whether to update the wireless signal information, based on the assessed position reliability.
