A method for the computer-aided determination of a control variable using context information from one or more units to be controlled is described. This method involves a controller using simulation to ascertain a piece of simulated context information which is used as a control variable, wherein the simulated context information comprises a first variable which represents a presumed state of the one or more units at a given time. The controller compares a received piece of context information, which comprises a second variable which represents the actual state of the unit to be controlled at a time which is before the given time, with the simulated context information and checks whether the simulated context information matches the context information within prescribed limits. In addition, the controller requests a piece of updated context information from one or more units to be controlled if the simulated context information matches the context information at the given time outside the present limits.

A query message is received at a first server of a plurality of servers of a first server type, at least part of data contained in the query message is transformed to a transforming result, based on the transforming result and a first lookup table at said first server, a storage location of a respective second lookup table at one of said plurality of servers of said first type is determined, the respective second lookup table is accessed at the determined storage location of the respective second lookup table at one of said plurality of servers of said first type, and an indicator indicating a storage location of data requested by the query message is retrieved from the respective second lookup table.

Query routing in distributed database system

A state change in a network comprising a master server among a plurality of servers is determined, at the master server, a first lookup table is calculated, said first lookup table indicating respective partitions of a second lookup table distributed among active servers of said plurality of servers, the calculated first lookup table is distributed to each active server, and based on the first lookup table, at the master server, a modified partition of the second lookup table is generated.

Distributed database system using master server to generate lookup tables for load distribution

The invention relates to a method for controlling the exchange of data between mobile subscribers in a packet-oriented mobile communication network, wherein management of each subscriber occurs at a specific control node (SGSN) of the mobile communication network according to the actual whereabouts of the subscriber inside the mobile communication network; links from/to a mobile communication transmitter device of the mobile subscriber are controlled inside the mobile communication network by the corresponding control node; wherein an address register comprising all of the addresses allocated to mobile subscribers managed by said control node is stored in the control network node; a destination address allocated to the data packets is read out in the control network node from incoming data packets and is compared to the address register by means of a search function; if the destination address is available in the address register, the data packets are exclusively handled by the control node in the mobile communication network and are further transmitted; if the destination address is missing in the address register, the data packets are transmitted by the control node to another network node (GGSN) of the mobile communication network for further processing.
