Abstract
A wireless communication terminal comprising a network communication unit, short distance wireless communication unit, an input unit and a control unit. The network communication unit transmits radio signals to communication network via a base station. The short distance wireless communication unit transmits radio signals to and from an external device. The short distance wireless communication unit establishes a voice link between the wireless communication terminal and the external device to transmit sound data. The input unit inputs a volume control instruction. The control unit controls the short distance wireless communication unit to send a signal based on the volume control instruction if the voice channel is established between the wireless communication terminal and the external device.
