PCT No. PCT/FI93/00399 Sec. 371 Date Jun. 6, 1994 Sec. 102(e) Date Jun. 6, 1994 PCT Filed Oct. 6, 1993 PCT Pub. No. WO94/08406 PCT Pub. Date Apr. 14, 1994A cellular radio network, and methods for updating location and setting up a call in a cellular radio network. The network comprises at least one mobile subsystem, which serves conventional mobile stations. The network knows the location of the subsystem and the mobile stations with an accuracy of a location area. The location data of a mobile station registered in the subsystem is the identification data of the subsystem, which is not updated again until the radio station leaves the subsystem. In the call set-up, a two-stage interrogation is conducted: first, the identifier of the subsystem is obtained as the location data of the mobile station; second, the current location of the subsystem where the call will be routed to is obtained by means of the identifier of the subsystem.
