The invention relates to a method and a communication system for improving the playback quality of audio signals which have been transmitted by radio, in particular by an aircraft (10), as a radiotelephony message (11), wherein k) at least one unchanged audio signal (1) is received by a communication system (12), the unchanged audio signal comprising a useful signal and an interfering signal, and the interfering signal being composed of a plurality of interfering signal components, l) the interfering signal components are removed from the audio signal, and an air traffic controller workstation (13) connected to the communication system plays said audio signal back to an air traffic controller (14) in real time as an audio signal which has been filtered by a filter, m) a differential signal between the unchanged audio signal and the filtered audio signal is formed in parallel with the playback at the air traffic controller workstation, n) a device for quality inspection checks the differential signal for any voice components of the radiotelephony message which may be present, and o) if a predetermined quality threshold value is not reached, an action at the air traffic controller workstation is triggered.

A system for locating a mobile communication terminal, the system having an interrogation device, which is configured to solicit a mobile communication terminal of a wireless communication network to establish temporary communication with the interrogation device in an original bandwidth employed for communication between the interrogation device and the mobile communication terminal. Processors configured to isolate the uplink bandwidth of the mobile communication terminal by: configuring the interrogation device to remove a downlink bandwidth, to the wireless communication terminal, from an end of the original bandwidth to create a new downlink bandwidth; calculating an uplink bandwidth at the end of the original bandwidth to be less than the bandwidth removed from the downlink bandwidth; and reconfigure the mobile communication terminal to uplink to the interrogation device on the calculated uplink bandwidth at the end of the original bandwidth. The system further comprising a power detection device (PDD) configured to measure a power of a radio frequency (RF) signal emitted by the mobile communication terminal and having bandwidth filter configured to measure less than a calculated uplink bandwidth and locate the mobile communication terminal.
