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 fulfillment 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 fulfillment 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).
