Abstract
A method of operating a mobile wireless network is provided, in which, when there is a relocation, the connection may be continued essentially directly from the latest state before the relocation. User data is transmitted between a mobile station and a first base station, the user data being combined into data units, for example, packet data units, before being transmitted. For transmission of data units, transmission-specific information describing an instantaneous state of the transmission is stored in the mobile station, as well as in a first network unit at a higher level than the first base station. With the relocation of the mobile station from the first base station to a second base station having a second higher-level network unit, the transmission-specific information stored in the first higher-level network unit is transmitted to the second higher-level network unit to continue the transmission after the relocation essentially directly from its latest state.
