Abstract: 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.

Abstract: 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.

Abstract: Method for deactivating at least one mobile station in a radio communication system, particularly in a picocell on board an aircraft in a GSM mobile radio network, where the radio communication system has a first network element, which forms a transmission/reception device for each mobile station in the radio cell, a second network element which is set up to control the first network element, and a device which is connected between the first network element and the second network element, wherein the device carries out the following steps: detection of a piece of identification information, directed at the at least one mobile station, which is transmitted from the second network element to the first network element, use of this identification information to deactivate the at least one mobile station when a deactivation signal is supplied to the device.

Abstract: In a method for operation of a device in a radio access network of a radio communication system, the device is arranged between a first network element and a second network element of a radio access network, receives at a first point in time from the first network element a first heartbeat and sends to the first network element at a second point in time a first acknowledgement signal as a response to the first heartbeat, with the first acknowledgement signal signaling to the first network element that a connection exists between the first network element and the second network element. At a third point in time the device sends a second heartbeat to the second network element, with the second network element, on receiving the second heartbeat sending as a response a second acknowledgement signal to the device in order to signal to the device the existence of a connection between the device and the second network element.

Abstract: A device receives from a base station speech data encoded with a first speech codec, transcodes the speech data into a second speech codec and transmits the speech data encoded with the second speech codec toward a base station controller used for controlling the transmission of the speech data.
