Abstract

Node, computer software and method for preventing an external party (114) to map an identity of a network cell (122) of a telecommunication network (112 or 120) with a corresponding geographical location of the network cell (122). The method includes receiving at a base station (200) of the telecommunication network (112 or 120) system information from a radio network controller (203) of the telecommunication network (112 or 120); extracting, at the base station (200), the identity of the network cell (122) from the received system information; changing, at the base station (200), the identity or one of multiple parts of the identity of the network cell (122); and sending the changed identity or the one of multiple parts of the identity to a user terminal (80).
