Abstract
Abstract For a transmitter of a mobile station of a radio communication network which is typically a mobile radio telephone network, a power supplying arrangement is intermittently energized before being continually energized to allow the transmitter deliver a speech signal to another mobile station through a base station of the network. More particularly, the power supplying arrangement is temporarily energized in response to a down-loop indicating signal, and transmits a specific up-loop signal after which it is deenergized immediately subsequent to transmission from the transmitter of a known pre-call response signal. After this operation, it is preferable that the power supplying arrangement is intermittently energized upon reception of an intermittent succession of call signals and then continuously energized after the mobile station is put into an off-hook state for transmission of the speech signal.
