Abstract

A 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.
