Abstract: A technique for identifying a geographical location of a mobile terminal which includes receiving a set of characteristics from the mobile terminal, comparing the set of characteristics from the mobile terminal with a set of attributes for each of the cells, and identifying one of the sub-cells whose attributes most closely match the characteristics from the mobile terminal as the subcell in which the mobile terminal located. The attributes may include discrete RF attributes, such as average pilot strength, chip offset, or pilot strength. The attributes may also include continuous features, such as signature waveforms.
