1. A method comprising:
- receiving a position of a device;
receiving identity information of a cell;
examining a data base to find parameter information relating to the received identity information;
retrieving from the data base the parameter information; and
determining whether the data base is to be updated with the position data of the device;
wherein if it is determined that the data base is to be updated, the method further comprises updating the data base by using the position data of the device,wherein the method also comprises using the data base to calculate a default position of the device, then utilizing the default position to search for signals from satellites, and then utilizing said signal from said satellites to calculate a more precise position of the device than the default position, andwherein said determining whether the data base is to be updated employs one skipping rate at one speed of the device and employs another skipping rate at an other greater speed of said device,wherein said data base is updated less often at said one skipping rate which is greater than said other skipping rate.

Abstract
A method for updating a data base which includes positioning data and identity information of a cell, the method comprising receiving a position of a device and receiving identity information of a cell. The data base is examined to find parameter information relating to the received identity information. The parameter information is retrieved from the data base. It is determined whether the data base is to be updated with the position data of the device, wherein if it is determined that the data base is to be updated, the updating of the data base is performed by using the position data of the device and the value of an updating parameter is updated.
