Abstract: A method is proposed for operating a mobile radio network, which permits an error-free exchange of packet data units in the event of a connection change between a mobile unit and superordinate network units. In this regard, useful data is transmitted between the mobile unit and a first radio base station, the useful data being combined to form packet data units prior to its transmission. For the transmission of the packet data units, transmission-specific information describing an instantaneous state of the transmission is stored both in the mobile unit and in a first network unit superordinate to the first radio base station.

Abstract: The present invention provides a data transfer method for use in a CDMA system operating in the TDD mode. A data signal is transmitted in the form of a data stream of data bursts of different users between a first station and a second station via a multiplicity of antennas, and a reference signal is transmitted in connection with the specific data burst. In a first step, a reference signal is transmitted from the second station to the first station. In a second step, a channel estimation is performed in the first station based on the reference signal that is received from the second station. In a third step, the first station transmits a data burst to the second station via the multiplicity of antennas, it being possible to modify the transmission signals of various antennas having various amplitude and phase factors in accordance with the channel estimation.

Abstract: A method for operating a mobile radio network is proposed which makes possible improved error protection of the control data to be transmitted while requiring as small a transmission bandwidth as possible. In this context, payload data is transmitted in payload data packets. The payload data packets are each assigned at least one header information item containing control data for routing the payload data packets in the mobile radio network. The control data and the payload data are transmitted with different error protection.

Abstract: A method for controlling and evaluating message traffic of a communication unit uses a first network unit within a mobile radio system for forwarding all the messages of the message traffic. The first network unit decides, using one or more useful information items of the communication unit, whether one or more messages are forwarded to a second network unit for processing or whether they are blocked. The first network unit is also used to determine, using one or more useful information items of the communication unit, whether the respective message of the message traffic is logged by the first network unit in a logfile.

Abstract: A method of operating a mobile wireless network is described to ensure proper function of protocol entities during the transmission of data units between two wireless stations of the mobile wireless network. In this case, user data is assembled by a first convergence protocol layer of the first wireless station into at least one first data unit, particularly a packet data unit, before transmission to a second convergence protocol layer of a second wireless station, particularly on the same protocol level, with the user data being supplied to the first convergence protocol layer by at least one user in a network layer. At least one protocol entity of the first convergence protocol layer is configured as a function of a configuration request received by the second wireless station, in order to form the at least one first data unit from the data received from the at least one user and to transmit it through a carrier to a link control layer.

Abstract: In a cellular radio communication system, at least one locating measuring signal is emitted by at least one additional positioning element from at least one radio cell. According to the invention, each positioning element monitors the radio signalizing on the common air interface of the respective base station to see whether a positioning inquiry signal is emitted to said station and/or from said station. When detecting a positioning inquiry signal of said type, a monitoring positioning element of said type independently inserts at least one locating measuring signal into at least one free signal section of the radio signaling.

Abstract: A method is provided for transmitting data packets, which includes sending a data packet from a sender (S) to a recipient (E), and; sending a confirmation message from recipient (E) to sender (S) in order to confirm the receipt of the data packet. When sending the data packet, a timer for monitoring the receipt of the confirmation message is started. According to the present invention, no charges for the transmission of the data packet are assessed when no confirmation message from the recipient (E) arrives within a time frame initiated by the timer.
