Abstract: A network comprising a base station, a downlink base station and an out station. The base station is configured to transmit a first downlink signal including downlink data intended for the out station. The first downlink signal is not received and processed by the out station. The downlink base station is configured to receive the downlink data intended for the out station and transmit a second downlink signal including the downlink data intended for the out station. The second downlink signal may be received and processed by the out station and not by the base station. The out station is configured to receive and process the second downlink signal and transmit an uplink signal including uplink data. The uplink signal may be received and processed by the base station and not by the downlink base station. The base station is configured to receive and process the uplink signal.

Abstract: The audio input system (6) of a terminal, such as a mobile telephone, is powered up during the standby mode, either with the paging channel or any other short duration channel such as a monitoring channel, and is then used to recognise narrow bandwidth sounds such as a whistle, to activate the telephone. Once activated, the telephone may then be responsive to voice commands and may then support a speaker phone mode of application.
