摘要： A signal processing device for configurable voice activity detection. A plurality of inputs receive respective microphone signals. A microphone signal router configurably routes the microphone signals. At least one voice activity detection module receives a pair of microphone signals from the router, and produces a respective output indicating whether speech or noise has been detected by the voice activity detection module in the respective pair of microphone signals. A voice activity decision module receives the output of the voice activity detection module(s) and determines whether voice activity exists in the microphone signals. A spatial noise reduction module receives microphone signals from the microphone signal router, and performs adaptive beamforming based in part upon the output of the voice activity decision module, and outputs a spatial noise reduced output. The device permits simple configurability to deliver spatial noise reduction for one of a wide variety of headset form factors.

摘要： An interworking system, for example for use in an access point, has a first air interface, for establishing a connection with a UE in accordance with a 3GPP air interface standard; and a second air interface, for establishing a connection with said UE in accordance with a WLAN standard. The interworking system is able to establish a connection with a 3GPP core network for carrying traffic for the first air interface, and is also able to establish a connection with the 3GPP core network for carrying traffic for the second air interface. The connection with the 3GPP core network for carrying traffic for the first air interface may comprise a PDP context, and the connection with the 3GPP core network for carrying traffic for the second air interface may comprise the same PDP context or may comprise a separate PDP context.

摘要： A method of setting a maximum uplink power for user equipment devices in a coverage area of a first basestation located in a coverage area of one or more second basestations in a cellular communications network is provided. The maximum uplink power is set for user equipment devices based on a measure of the pathlosses between the one or more second basestations and user equipment devices in the coverage area of the first basestation. The measure of the pathlosses between the one or more second basestations and the user equipment devices is formed from a measure of the pathloss between the one or more second basestations and the first basestation and an estimate of the excess of the pathlosses between the one or more second basestations and the user equipment devices over the pathloss between the one or more second basestations and the first basestation.

摘要： An electronic device has two oscillators, for example a first highly accurate crystal oscillator and a second less accurate low power oscillator. In a normal mode of operation, time is counted based on an output from the crystal oscillator, but in a low power mode of operation, time is counted based on an output from the less accurate oscillator. During the low power mode of operation, a calibration process is performed repeatedly. During a first calibration time period the second oscillator is calibrated against the first oscillator to obtain a first calibration result, and a recalibration is performed during a second calibration time period to obtain a second calibration result. A correction factor is determined from the first and second calibration results, and the correction factor is applied when subsequently counting time based on the output from the second oscillator.

摘要： A wireless access device is operable in a mode in which its maximum transmit power is set to a value that means that the device has a range of less than 1 metre. This allows the device to operate as a basestation in a cellular communications network, even in locations in which it is not specifically licensed, because the power level is so low that it will not cause interference on the licensed frequencies. The wireless access device is designed such that a handheld portable device can be maintained in a close spatial relationship to it.

摘要： A neighbour cell list is formed, for use in a basestation of a cellular communications network. For each of a plurality of neighbour cells, a value of a first component is assigned, depending on whether or not the basestation can detect signals transmitted from said neighbour cell. A value of a second component is assigned, depending on a history of successful or unsuccessful handover attempts to said neighbour cell. The values of the first and second components are combined to form a weighting parameter, for use in determining a handover priority to be given to said neighbour cell in the neighbour cell list.

摘要： A noise cancellation signal is generated based on detected ambient noise, such that the noise cancellation signal and a wanted sound signal can be applied to a speaker. Gain control is applied to the wanted sound signal based on a comparison between the detected ambient noise level and the wanted sound signal level, for example such that the level of the wanted sound signal after the gain has been applied exceeds the level of a detected ambient noise signal by a certain threshold. Steps may also be taken such that the total level of the wanted sound signal after the gain has been applied and of the detected ambient noise signal do not exceed a second threshold, to avoid saturating the speaker to which they are applied.

摘要： A basestation, for a cellular communication network, is described. The basestation is adapted to store a list of user equipments that are authorized to access the network by means of the basestation. In the event that the basestation receives a location update request from an unauthorized user equipment, the basestation is adapted to send a reject message to the unauthorized user equipment. The reject message specifically identifies the basestation, such that the unauthorized user equipment does not attempt to send any further location update request to the basestation.
