1. A mobile terminal comprising:
- a positioning receiver; and
a processor circuit configured to identify an approximate geographic position of said mobile terminal by accessing a database comprising data representing a plurality of geographic positions provided by said positioning receiver, said approximate position corresponding to one of said geographic positions associated in said database with data representing a current cell identification number for a cell in which said mobile terminal is located.

Abstract
A mobile terminal and system and method for determining the geographic location of the mobile terminal. A current cell identification number is determined for a cell in which the mobile terminal is located. The geographic location of the mobile terminal is determined based on data including at least one geographic position stored in a database and associated in the database with data representing the current cell identification number. The database may be updated with the geographic location and the current cell identification number.
