A method for indicating a mobile station's (MS) location. A first radio network controller, RNC, acts as the mobile station's serving RNC (SRNC), for reporting the mobile station's location to the core network (CN). A second RNC acts as the mobile station's drift RNC (DRNC), for maintaining a radio connection with the mobile station. In response to fulfilment of at least one criterion in a first set of criteria, the mobile station (MS) sends location information about its location to the second RNC (DRNC) which forwards the location information to the first RNC (SRNC) for reporting to the core network (CN). There is also a second set of criteria for transforming the location information. In response to fulfilment of at least one criterion in the second set, the first RNC (SRNC) sends falsified information about the mobile station's location to the core network (CN).

Cette invention concerne un procédé permettant d'indiquer la position d'une station mobile (MS). Un premier organe de commande de réseau radio (RNC), qui fait office de RNC serveur la station mobile (SRNC), signale la position de la station mobile su réseau central (CN). Un second RNC fait office de RNC en déplacement et maintient la connexion radio avec la station mobile (DRNC). Lorsqu'au moins un critère est satisfait dans un premier ensemble de critères, la station mobile (MS) transmet des informations sur sa position au second RNC (DRNC) qui relaie l'information vers le premier RNC (SRNC) pour transmission au réseau central (CN). On trouve également un second ensemble de critères servant à transformer l'information sur la position. Si au moins un des critères du second ensemble est satisfait, le premier RNC (SRNC) transmet des informations falsifiées sur la position de la station mobile dans le réseau principal (CN).
