Abstract: A method for operating a wireless communication device in a cellular network comprising a plurality of base nodes, the wireless communication device is operating in enhanced coverage mode with a first base node of the plurality of base nodes. The method comprises:—measuring signaling from at least one second base node,—determining an indication relating to the camping priority of said second base node,—in case the second base node has a higher camping priority than the first base node, but the second base node does not support enhanced coverage mode and said measured signaling indicates insufficient suitability of the second base node to serve the wireless communication device in normal coverage mode:—suspending measurement of signaling of the second base node,—measuring signaling from at least a third base node providing the same camping priority as the first base node.

Abstract: A method for a wireless device of providing a voice service via packet switched communication with an operating cellular network, the wireless device is-being physically connected to an identification unit comprising a first memory block for storing at least one set of configuration parameters for voice service within a first cellular network. Prior to setting up a voice call, the device checks with the identification unit if configuration parameters applicable to the operating cellular network are available. If not, configuration parameters are requested from a parameter server accessible for the operating cellular network. The device receives said configuration parameters from said parameter server, and stores at least a portion of received configuration parameters in said first memory block of the identification unit. If the configuration parameters are available, the device applies said configuration parameters, and sets up a voice call using said configuration parameters.

Abstract: A method for detecting a jamming transmitter affecting a communication user equipment, operating in a cellular network supporting communication in a time-division manner, including at least one active base station, on which the user equipment is camping. In the method, the user equipment detects that at least one downlink radio channel from the active base station is not decodable, measures signal levels received on said downlink radio channel for a plurality of time units, analyzes said signal level measurements, and in case at least one time unit is detected with a signal level exceeding a predefined threshold, detects a jamming transmitter by verifying that, in a predefined amount of successive time units, the pattern of a first time unit with signal level exceeding the predefined threshold, directly followed by a second time unit with a signal level below the predefined threshold, is not detected.

Abstract: A method for operating a wireless communication device comprising a communication unit comprising a radio mode decision unit and a transceiver unit, the radio mode decision unit further maintaining a set of network operation modes, the wireless communication device further comprising a controlling appliance, interconnected with the communication unit by means of a command interface. The communication unit ascertains at least one communication behavior parameterization conforming to a preconfigured communication behavior demand of a cellular network1 The controlling appliance submits a transport template dataset comprising a data element relating to an envisaged communication behavior to the communication unit by means of the command interface. The radio mode decision unit determines, for an imminent data exchange session of the wireless communication device with the cellular network by means of the transceiver unit, one of said network operation modes by taking into account said communication behavior parameterization and said transport template dataset.

Abstract: A method for operating a low-mobility wireless device in a cellular network, wherein the low-mobility wireless device operates with an active base node, and the low-mobility wireless device operates in a first mode, in which measurements of transmissions of base nodes are diminished. When the cellular network is enhanced by a new base node, the active base node transmits a first indication at least to the low-mobility wireless device. The low-mobility wireless device, in response to the reception of the first indication, switches to a second mode of operation, comprising execution of at least one measurement of transmissions of base nodes, and transmits at least one measurement report to the then-active base node. The active base node, upon reception of a measurement report, updates neighbour relation data relating to the base node identified by a base node reference with information obtained from the received measurement report.
