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.

Claims

1. A mobile station for use in a radio communication network including a base station, said mobile station including a receiver, a transmitter, monitoring means coupled to said receiver for monitoring a down-loop indicating signal directed from said base station to said mobile station to produce a down-loop check signal, and power supplying means responsive to said down-loop check signal for supplying electric power to said transmitter, said transmitter being for transmitting a specific up-loop signal to said base station when supplied with said electric power in response to said down-loop check signal, wherein the improvement comprises:

deenergizing means coupled to said transmitter and said power supplying means for deenergizing said power supplying means upon completion of transmission of said specific up-loop signal; and

reviving means coupled to said deenergizing means and said power supplying means for reviving said power supplying means to make said power supplying means continuously supply said electric power to said transmitter after deenergization of said power supplying means by said deenergizing means.

2. A mobile station as claimed in claim 1, further comprising off-hook signal producing means for producing an off-hook signal, wherein said mobile station further comprises actuating means coupled to said off-hook signal producing means and said reviving means and responsive to said off-hook signal for actuating said reviving means to revive said power supplying means.

3. A mobile station as claimed in claim 1, wherein said monitoring means is further coupled to said deenergizing means for further monitoring a command signal directed from said base station to said mobile station after deenergization of said power supplying means by deenergizing means to produce a starting signal;

said mobile station further comprising additional actuating means coupled to said monitoring means and said reviving means and responsive to said starting signal for actuating said reviving means to temporarily revive said reviving means before said reviving means makes said power supplying means continuously supply said electric power to said transmitter.

4. In a mobile radio communication network including a base station and a mobile station, said base station including down-loop indicating signal producing means for producing a down-loop indicating signal, call signal producing means for producing an intermittent succession of call signals succeeding said down-loop indicating signal, and transmission means coupled to said down-loop indicating signal producing means and said call signal producing means for transmitting said down-loop indicating signal and said call signal succession towards said mobile station, said mobile station including a receiver, a transmitter, monitoring means coupled to said receiver for monitoring the down-loop indicating signal directed to said mobile station to produce a down-loop check signal, and power supplying means responsive to said down-loop check signal for supplying electric power to said transmitter, said transmitter being for transmitting a specific up-loop signal to said base station when supplied with said electric power in response to said down-loop check signal, the improvement wherein:

said base station comprises command signal producing means coupled to said transmission means for producing said command signal to make said transmission means transmit a command signal succeeding each of said call signals to said mobile station;

said mobile station comprising;

deenergizing means coupled to said transmitter and said power supplying means for deenergizing said power supplying means upon completion of transmission of said specific up-loop signal;

reviving means coupled to said deenergizing means and said power supplying means for reviving said power supplying means to make said power supplying means continuously supply said electric power to said transmitter after deenergizing of said power supplying means by said deenergizing means;

actuating means coupled to said monitoring means and said reviving means and responsive to said starting signal for actuating said reviving means to temporarily revive said reviving means before said reviving means makes said power supplying means continuously supply said electric power to said transmitter; and

confirmation signal producing means responsive to the command signal directed to said mobile station for producing a confirmation signal;

said base station further comprising;

reception means for receiving a confirmation signal to produce a reception signal; and

control means coupled to said reception means and said transmission means and responsive to said reception signal for controlling transmission of said call signal succession from said transmission means.
