A method, system and device are provided for carrying out a login procedure of a mobile terminal into a mobile communications network. To compensate for a time delay on the communications channel between a base station and a control unit, a device is inserted into the connection between the base station and the control unit. The device is arranged between the base station and the section which is subject to time delay in the communications channel. The device stores the query reference broadcast by the mobile terminal device during each initiation of a login procedure and replaces the query reference in the reply with the query reference currently stored in this device. Thus, the mobile terminal device can carry out the login procedure even in the presence of time delays on the connection between the base station and the control unit.

A method, system and device for reducing volume of data transmitted between a base station and a control unit in a mobile communications network in which there is inserted into a communication channel between the base station and the control unit a device are provided. Voice data transmitted in each communication channel and associated with a plurality of connections is analyzed. Each connection also includes signaling data a signaling channel, and the connections originating from a base station and terminated in the same or a different base station connected to the device are identified and interconnected, and following the interconnection of the voice channels the transmission of the associated voice data to the control unit is prevented. Thereby, the data volumes transmitted on the voice channels are no longer forwarded to the rest of the mobile communications system and consequently the data volumes transmitted are reduced.

Method, system and device for reducing data in a mobile communications network

A method for selecting satellite channels in a transmission system consisting of a data source, a data sink, satellite modems and a satellite radio link with a general channel and at least one dedicated channel is provided. The data sink prompts the data source, as a function of the transmission characteristics of the general channel, to set up a dedicated channel for further data transmission.
