  • Patent number: 8411652
    Abstract: A method of operating a mobile radio network for adjusting the counter states of the packet data units to be transmitted in the convergence protocol layer protocol units of network entities of the mobile radio network. User data is transmitted from a first network entity of the mobile radio network, in particular a mobile station, to a second network entity of the mobile radio network, in particular a higher-level network unit, the user data is combined prior to transmission into at least one packet data unit in a first convergence protocol layer protocol unit of the first network entity; and the at least one packet data unit is transmitted from a first radio link control layer protocol unit of the first network entity to a second radio link control layer protocol unit of the second network entity.

  • Publication number: 20130072159
    Abstract: A method for confirming identity of a physical unit (M) in an open, wireless telecommunications network, having the following steps: storing a secret identity (SIMEI) and an open identity (IMEI) in memory in the physical unit (M); receiving an identity request (IR) with a first parameter (CHv) from the testing device (P) at the physical unit (M); generating an electronic signature (SIGt) by means of a first cryptographic function (F3) from the secret identity (SIMEI) and at least the first parameter (CHv) in the physical unit (M), and sending the generated electronic signature (SIGt) and the open identity (IMEI) to a testing device (P); wherein the identity of the physical unit (M) is confirmed if the electronic signature (SIGt) matches a corresponding electronic signature (SIGv) generated by the testing device by application of a first cryptographic function to the secret identity (SIMEI).

  • Publication number: 20130035106
    Abstract: A method of operating a mobile wireless network ensures proper function of protocol entities during the transmission of data units between two wireless stations. 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.

  • Patent number: 8078213
    Abstract: A slave station and a method of regulating the transmission power a master station are described, which permit an estimate of the signal/interference ratio in a transmission system without sending a pilot sequence, the transmission power being regulated as a function of an estimate of the signal/interference ratio. In a transmission system, in particular a CDMA transmission system, useful signals assigned to different communicating subscribers are separated by orthogonal codes. A useful signal assigned to one communicating subscriber is derived by using one of the codes from a signal received at least in the slave station from the master station and is compared as a reference signal with the received signal to estimate the signal/interference ratio.

  • Patent number: 8036712
    Abstract: A radio apparatus embodied in a radio telephone has a display device and at least one control element for selecting and/or activating functions of the radio apparatus that are displayed on the display device. The control element is disposed neighboring the display device so that a local association exists between the control element and the displaying of functions of the radio apparatus on the display device. The apparatus further includes means for providing at least one first operating mode in which information about the first operating mode is associated in the display device with the control element. Information in a second operating mode associated with the first operating mode is converted into a function for activating the first operating mode, which function is activateable by the control element.

  • Patent number: 8031659
    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.

  • Patent number: 7991438
    Abstract: A mobile telecommunications terminal is provided, which makes possible, so as to use the least possible amount of power, a query of messages present for the mobile telecommunications terminal in a telecommunications network. The mobile telecommunications terminal includes a receiving device for receiving messages from the telecommunications network in a receive mode. At the mobile telecommunications terminal, a query mode can be established, in which a control unit, in the event that the receive mode is switched off, activates the receive mode at at least one first predetermined time. The control unit checks whether, within a second predetermined time period after the activation of the receive mode, information was received in the receiving device regarding at least one message present in the telecommunications network (10) for the mobile telecommunications terminal.

  • Patent number: 7904098
    Abstract: A method of assigning transmission channels in a telecommunications network and a user station are provided, which facilitate an increase in the capacity of a telecommunications network. The telecommunications network may include multiple base stations and mobile stations, the transmission channels being provided for transmitting signals between the base stations and the mobile stations. In uncoordinated operation of the base stations, at least one of the transmission channels is assigned for transmitting signals between one of the base stations and one of the mobile stations as a function of a channel measurement, in which the transmission power on all possible transmission channels is measured, if the previously measured transmission power on this transmission channel is minimal.
