Claim:
A method for preventing an external party to map an identity of a network cell of a telecommunication network with a corresponding geographical location of the network cell, the method comprising: receiving at a base station of the telecommunication network system information from a radio network controller of the telecommunication network; extracting, at the base station, the identity of the network cell from the received system information; changing, at the base station, the identity or one of multiple parts of the identity of the network cell; and sending the changed identity or the one of multiple parts of the identity to a user terminal, wherein the changing step further comprises: generating a new identity for the network cell, wherein the new identity has multiple parts; changing in the radio network controller a current identity of the network cell with the new identity; and instructing the base station, which is controlled by the radio network controller and which controls the network cell, to replace a current second portion of the current identity with a new second portion of the new identity of the network cell.
