LOCATION DEPENDENT SERVICE FOR MOBILE TELEPHONES

A mobile telephone system provides a subscriber with services, for instance call barring and call forwarding, in dependence on the circumstances of the subscriber's mobile station. For instance, if the mobil e station (1-9) has a first network (1) as its home network, the services provided are modified if it is detected that the mobile station (1-9) has registered with a second network (3). In particular, international calls may be barred when on the home network, but permitted wh en on the second network so that the user may call his home country. This is carried out by having a number of different service profiles stored in the home network (1-3) for controlling the interactions between the mobile telephone and the current network (1, 3), these service profiles being selected according to which network (1, 3) the mobile telephone (1-9) is currently working to.
