PCT No. PCT/FI95/00191 Sec. 371 Date Oct. 4, 1996 Sec. 102(e) Date Oct. 4, 1996 PCT Filed Apr. 6, 1995 PCT Pub. No. WO95/28063 PCT Pub. Date Oct. 19, 1995A location management method is provided for packet data transmission in a mobile communication system. To reduce the amount of signalling for location management concerning packet transmission compared to location management concerning normal traffic, location data of the mobile stations utilizing a data service is updated in a special data service user database. Packets to these mobile stations are sent via the cells as indicated by location data in that database. The database resides in a data service center which interfaces a data network.
