摘要
A TETRA system comprises a monitoring communication unit (107) performing an ambience listening service for a monitored communication unit (101). The monitored communication unit (101) comprises a transmitter (109) for transmitting the ambience listening mode transmissions to the monitoring communication unit (107) which comprises a receiver (117) for receiving these. In addition, the monitoring communication unit (107) comprises a command controller (119, 121) which determines and transmits transmission parameter commands to the monitored communication unit (101) where they are received by a receiver (113). The monitored communication unit (101) comprises a transmission controller (115) which sets at least one transmission parameter of the ambience listening mode transmissions in response to the transmission parameter commands. The monitoring communication unit (107) may accordingly control aspects of the transmission from the monitored communication unit (101) and may in particular reduce the transmit power or the transmit time thereby reducing power consumption, heating and interference.
