Abstract

A mobile telephone device comprises a separate paging signal channel in addition to the conventional transceiver channels which process voice signals. The paging signal channel has a lower power consumption level than the transceiver channels. A power supply control device shuts off power to the conventional transceiver channels when in a standby mode, i.e. when waiting for an incoming call, and applies power to the paging signal channel instead. Therefore, power consumption is reduced in the standby mode and consequently, the operating time of the battery is extended. Power is applied to the transceiver channels during voice communication periods. A calling party's telephone number received in the paging signal channel is stored and displayed. A control unit has the capability of immediately returning the calling party's call from the telephone number so stored and displayed. <IMAGE>

An example of a mobile telephone device is "Personal Portable Cellular Telephone" Model 900, manufactured by Mitsubishi Electric Corporation.

Fig 3 is a perspective view showing the external appearance of a conventional type of paging receiving device, and Fig 4 is a block diagram for showing a circuit configuration of Fig 3 In the figures, 201 denotes an antenna, 203 a receiving part for demodulating a high frequency signal into a base band signal, 204 a data demodulation part for demodulating a base band signal into a digital signal, 205 a CPU for analyzing the received data of the digital signal, 207 a displaying part, 208 an operating part, 209 a buzzer for informing the presence of a call to an operator, 210 a battery acting as a power supply for each of the blocks, and 211 is a DC/DC converter for converting an output voltage of the battery 210.

An example of a paging device is an "RDS FM pager type FR-50 E (for Swedish System)" manufactured by Mitsubishi Electric Corporation, i - The operation of each of the circuits of Figs 2 and 4 will now be described First, an operation in which a portable telephone set is called up from a base station and the like will be described A signal containing a call signal transmitted from the base station is received by the antenna 101 A required frequency band is filtered out from this signal by the receiving filter 152 Then, the receiving part 154 may use a tuning frequency supplied from the frequency synthesizer 155 to demodulate the filtered signal into a base band signal and output it to the data modulaticn/demodulation part 157 The data modulation/demodulation part 157 may demodulate the base band signal into a digital signal and then output it to the CPU 105 The CPU 105 may ring the buzzer 109 to call up the operator upon sensing a call signal in the digital signals.

When the operator acknowledges the sound of buzzer and depresses a transmitting key to the operating part 108, the CPU 105 may acknowledge this depressing action and initiate a return call via the base station After this operation, the operator may use the microphone 160 and the ear piece 159 to communicate During this period, the voice signal processing part 158 may process the voice signal, a voice signal inputted frcm the microphone 160 is outputted as a base band signal and the base band signal input from the receiving part '54 becomes a voice signal and is outputted to the ear piece 159 The transmitting part 156 and the receiving part 154 may perform a modulation and a demodulation between the base band signal and the predetermined frequency signal The signal modulated at the transmitting part I 156 is transmitted from the antenna 101 and the signal received at the antenna 101 is inputted to the receiving part 154 Under a waiting (standby) condition for receiving a call signal, power must be supplied from battery 161 to the receiving part 154, frequency synthesizer 155, data modulation/demodulation part 157, CPU 105, memory 106, displaying part 107, operation part 108 and buzzer 109.

The operation of the paging receiving machine shown in Figs 3 and 4 will now be described With respect to the paging receiving machine, an example will be described in which the machine is operated by a voltage having an output voltage of battery 210 converted into a 5 V through DC/DC converter 211 In a similar manner as that of a portable telephone set, a signal sent from a base station, or the like, is passed through the antenna 201, receiving part 203 and data demodulation part 204 and then converted into a digital signal After receiving the digital signal, the CPU 205 detects a call signal from a calling party and stores a message contained in the call signal into the memory 206, and at the same time, displays it at the display part 207 It further rings the buzzer 209 to call up the operator.

The operator acknowledges the sound of the buzzer, looks at a message displayed at the displaying part, and can perform a corresponding countermeasure For example, in case the message is a telephone number of a calling party, the operator can communicate with the party through another totally separate communication means, such as a public telephone system.

Since the conventional type of portable telephone set is constructed as above in Fig 2, a power supply must always be supplied to the frequency synthesizer 155 in such a way that the operator can monitor the calling C 5 signal in a standby mode, resulting in substantial consumption of power during the waiting (standby) time, so the charge on battery 161 is depleted, shortening the operating time thereof.

Although the conventional type of paging receivine machine of Fig 4 has a lower power consumption level and a longer operating time of the battery 210, as cc pared with that of the portable telephone set of Fig 2, it has other disadvantages For example, in the case where communication is required after being called up, a telephone number of called party displayed at the displaying part 207 of the paging receiving machine be manually input into a separate telephone systen to perform a communication, resulting in an inconvenience and so a long time passes before the communication is started.

SU FiARY OF THE INVENTION The present invention eliminates the above-described problems and its object is to provide a mobile telephone device in which operating time for a given battery can be extended, initial communication can be carried out with a paging device which receives a call and a call can be transmitted to a calling party at once after the call signal is received by the paging device.

The objects of the present invention are fulfilled by providing a mobile telephone device comprising:

an antenna for receiving and transmitting high frequency communication signals; operator input/output means for enabling an operator to input data or voice communications into said telephone device or receive data or voice communications from the device, said input/output means including, means for generating a standby signal for initiating a call waiting period (standby time) in which the telephone device can receive incoming calls, and means for generating a transmit (talk) _si,cal for initiating a voice transmission period (talk time) in which the telephone device can transmit and receive voice and data communications; control means connected to said operator input/output means for receiving said standby and transmit signals to place said telephone device in either standby or voice transmission (talk) modes, respectively; first signal processor means for receiving and transmitting voice and data communication signals from and to the antennae, and transporting said voice and data communication signals between the antennae and ithe control means, said first signal processor means having a first power consumption level when energized by electrical power; second signal processor means for receiving data communication signals of incoming calls from the antennae and transporting the data communication signals from the antennae to the control means, said second signal processor means having a second power consumption level when energized by electrical power which is lower than the first power consumption level of the first processor means; power supply means for energizing the telephone device with electrical power; and power supply control means, responsive to the control means placing the telephone device in the standby mode, for selectively supplying said electrical power only to said operator input/output means, control means and second signal processor means, and responsive to the control means placing the telephone device in a voice I transmission mode, for also supplying said electrical power to said first signal processor means.

The high frequency communication signals received or transmitted by the antenna include first high frequency signals and second high frequency signals of different respective frequencies.

The first processor means is a conventional mobile telephone transceiver and it processes only the first high frequency signals, i e the carrier frequency and information modulated thereon of conventional cellular telephone systems.

The second processor means can be a conventional receiver nortion of an FM paging device and it processes only the second high frequency signals (paging signals), i e the carrier frequency of the FM pager.

The system of the present invention prolongs the operating time of a battery used in a mobile telephone device The operating time includes the sum of "standby" time and "talk' time "Standby" time is the time that a mobile telephone device has the power turned on while waiting for an incoming call from a calling party.

"Talk" time is the cellular air time, or the time that voice communications are conducted between the mobile device and the calling or called party's telephone By removing power from a majority of the components of the mobile telephone device, especially the frequency synthesizer, during "standby" time, the operating time of the battery can be extended The second signal processor means (the FM pager) subsystem makes this possible, since it consumes far less power than the first signal processor means (the telephone transceiver); and, therefore, the FM pager can be used to receive paging signals, including a calling party's telephone number.

For purposes of the following description, the mobile telephone device of the present invention may be considered to be in a "standby mode" during 'ls 4 anby" time, and in a "talk mode" during "talk" time.

Fig 5 B is a detailed circuit diagram of the power control part 162 in Fig 5 A Reference numeral 401 depicts a main power switch which is directly controlled by means of a power supply key on the key pad of the operating part 108 and turns on and off the power of the battery 161 The output of the main power switch 401 is connected to an automatic voltage regulator (AVR) of 5 V and a power switch 402 for the automqbile telephone transceiver portions of Fig 5 A including parts 154, 155, 156, 157 The AVR 403 generates an output of 5 V D C and applies power to paging portions 103, 104 and control part 115, 116 Switch 402 is turned on and off by a power supply control line from CPU 115 The output of switch 402 is directly transmitted and supplies the power to the radio transceiver portions 154, 155, 156, 157 of the automobile telephone, and to the voice signal processing part 158 via AVR 404 Switches 401 and 402 may be any suitable type of semiconductor switches known in the art.

The operation of the mobile telephone set of Figs.

A and SB will now be described in reference to the flow chart shown in Fig 6 After a power supply switch on keyboard 108 is turned on, that is, during a waiting (standby) period, power is supplied from the battery 161 via switch 401 and AVR 403 to portions 103, 104, 115, 116 but not to the portions 154, 155, 156, 157 enclosed by the doted line in Fig 5 (step ST 100) The high frequency signal received at the antenna 111 passes through the paging filter 102 and then is inputted into the paging receiving part 103 The CPU 115 detects a call signal in the digital signal demodulated by the paging receiving part 103 and the paging data demodulation part 104, and stores a message (received data) contained in the call signal in the memory 116.

In case that the received data is not a telephone number of a party to be called up, the received data is displayed at the display part 107 (step ST 104), rings the buzzer 109 for a specified period of time to inform the operator (step S Tl O 5).

In case that the data is a telephone number of a party to be called up in step ST 103, the received data is transferred to and registered in a region spetlfied for telephone numbers to be called from the memory 116 (step ST 106) When a telephone number is inputted independently of a received call from the operating part 108 (the keyboard) of the mobile telephone set, it is displayed on the display part 107 Likewise, when the telephone number of a party to be called up, received through the paging portions of Fig 5 A is received, it is displayed in the displaying part 107 in a similar fashion (step ST 107) In addition, an instruction is applied tc the power supply control part 162 and switch 402 therein in such a way that the buzzer 109 may be rung via part 158 (step ST 10 i) and both the transmitting and receiving of voice communications can be performed.

Also, the power supply control part 162 via switch 402 connects each of the non-energized blocks 154, 155, 156, 157 with the battery 161 (step ST 109).

Under this condition, if the transmitting key ("SENUD" key on keyboard 108) is depressed, the CPU 115 will acknowledge this depressing operation and stop the ringing of the buzzer 109 The CPU 115 may then execute an instantaneous calling program, retrieve a telephone number of a party to be called from memory 116 as a digital control signal from the telephone number region thereof and then output it as a digital control signal to the data modulation/demodulation part 157 The telephone number of the party to be called up becomes a base band signal at the data modulation/demodulation part 157 Further, the telephone number of the party to be called up is modulated at the transmitting part 156 as a control signal and then transmitted to the base station of a cellular system from the antenna 111 through a transmitting filter 153 (step ST 112) Thereafter, a conversation may be carried out in the cam manner as would be done with a conventional type of mobile telephone set (step ST 113), and, thereafter, an "end of conversation" signal is received from the base station, or from depression of an end of conversation key on keyboard 108, and the conversation is terminated (step ST 114) Then the CPU 115 may execute an instruction program and give an instruction to the power supply control part 162 and once again shut off the battery 161 from each of the blocks enclosed by the dotted line in Fig 5 A That is, the system returns to its waitina (standby) condition (step ST 116) In case that the transmitting (SEND) key is not depressed at the step ST 1 l O within a specified period of time, CPU 115 may execute the program of storing the telephone number of a party to be called up, display the fact that the call was received at the display part 107, stop the ringing of the buzzer 109, and return to the waiting (standby) condition (step S Till).

Fig 7 illustrates a mobile telephone device according to a second preferred embodiment in which in addition to the circuit configuration shown in Fig 5 A and 5 B, a voice responding part 120 is added and voice responding means is added to the CPU 125 The voice responding part 120 is comprised of ROM in which a predetermined message is coded and a decoding circuit for use in converting the coded data within the ROM into a voice signal For example, a coding system can be realized through ADPCM (Adaptive Differential Pulse Code Modulation) and a decoding circuit can be realized with a ADPCM decoding LSI, such as a type MSM 6258, ADPCM production/reproduction IC manufactured by Oki Electric Industry Co, Ltd With this arrangement, a more effective processing can be realized in the event that the transmitting (SEND) key is not depressed within a specified period of time at step ST 110 in Fig 6.

Referring now to the flow charts of L Figs 6 and 8 (A), the operation of the circuit of Fig 7 will be described CPU 125 may detect a telephone number of a party to be called and perform each of the functions in steps ST 106 to ST 109 Thereafter, if the transmitting (SEND) key is not depressed within a spec: ied period of time (step ST 110), the circuit of Fig 7 may perform the processing of Fig 8 A subsequent to the step ST 200 At first, CPU 125 may execute the instantaneous call program, retrieve the telephone number of a party tc be called out of the region of the telephone numbers in memory 126 to be used for calling, and then output the telephone number of the party to be called up to the transmitting part 156 through the data modulation/demodulation part 157 so as to call the number (step ST 200) If the party to be called up responds to the call, CPU 125 may execute the voice responding program therein and output a coded message indicating the absence of a party at the mobile telephone, said message being stored in the ROM of the voice responding part 5 z 6 including the ADPC:4 decoding LSI The ADPC'I decoding:Si converts the coded message into a synthetic voice -message and then outputs it to the voice signal processing part 158 In this way, a synthetic voice message indicat ng the absence of a party at the mobile telephone is sent out to the calling party (step ST 201) Upon completion of the sending of the synthetic voice message, it causes the communication to be automatically terminated (step ST 203) and the mobile telephone is returned back to its waiting (standby) condition (step ST 204) At this time, the fact that the call was received may be displayed on display 107.

In the above-described preferred embodiment, a system having a voice responding means added within CPU 125 has been described However, a means for transferring a message to a remote location may also be added to CPU 125 (a third preferred embodiment) That is, as shown in Fig 9, a ROM at the voice responding part has stored voice messages corresponding to " 1 " to " O " (that is, "ichi" to "zero" in Japanese phonetics) and voices of proper messages (" ni denwa o shite kudasai" in Japanese phonetics in Fig 9) which are coded as data in advance Further, a transfer telephone number (the number of a remote telephone device to which the message shall be forwarded) inputted from the keyboard 108 is stored in advance in a transfer telephone number region in the memory 126 (step ST 210) Under this condition, in the event that a depression of the transmitting (SEND) key could not be detected in step ST 110 in Fig 6 within a specified period of time, CPU 125 may perform operations subsequent to step ST 211 indicated in Fig.

8 B At first, CPU 125 may execute the transferring program and output a telephone number to which the message is to be forwarded stored in the transfer telephone number region to the data modulation/demodulation part 157 Then a call is placed in the same manner as that of the first preferred embodiment (step ST 211) Then CPU 125 executes the voice responding program and outputs the coded data corresponding to each of the digits of the calling telephone number stored in the calling party's telephone number region in the memory 126 in sequence to the LSI for the decoding ADPCM Then, it may output a message within the ROM upon completion of the output of the coded data corresponding to all digits (step ST 212) As described above, in this way, it is possible to deliver a voice message of ( ni denwa o shite kudas-ai in Japanese phonetics)) in addition to the calling party's telephone number to be called up to an operator who is present at the remote location to which the message is forwarded Operations after completion of delivering of the voice message (steps ST 213 and ST 214) are similar to that of the above-described preferred embodiments.

Fig 10 is a block diagram showing a circuit configuration of a mobile telephone device according to a fourth preferred embodiment of the present invention.

This preferred embodiment is an ex 3 mple in which the mobile telephone device is comprised of a main body 390 of a wireless device and a handset 391 and in particular, it is an example of a mobile telephone device to be installed in a vehicle In the figure, 301 denotes a common antenna for use both in paging and mobile telephone functions, 302 a receiving filter for the paging function, 303 a receiving part for the paging function, 304 a data demodulation part for the paging function, 305 a a CPU (a control part) at a main body for controlling the main body 390 of a wireless device, 306 a memory which CPU 305 a at the main body uses, 352 and 353 a receiving filter and a transmitting filter, respectively, 354 a receiving part, 355 a frequency synthesizer, 356 a transmitting part, 357 a data modulation/demodulation part, 358 a a voice signal processing part at the main body 390 of the wireless device, 362 a power supply control part (similar to part 162 of Fig 5 B) at the main body 390 of the wireless device and 320 a voice responding part 305 b denotes a CPU at the handset for controlling the handset 391 (a control part at the handset), 307 a display part, 308 an operation part, 358 b a voice signal processing part at the handset 391, 359 an ear piece, 360 a microphone, 363 a speaker, and 362 b a power supply contebl part-athe handset The operation of each of the blocks described above is similar to that corresponding to each of the blocks shown in Fig 7 In Fig 10, a speaker 363 is arranged as a ringing element in place of the buzzer 109.

The operation of the device will now be described in reference to the flow chart shown in Fig 11 After turning on the power supply switch (not shown) only the portion outside of the dotted line in Fig 10 is supplied with electrical power from an external battery (power supply means) through power supply control portions 362 a and 362 b (step ST 300) Then the CPU 305 a at the main body detects a calling signal in a digital signal decoded by the paging receiving part 303 and the paging data decoding part 304 (step ST 301) and stores the message data (received data) contained in the calling signal in the memory 306 (step ST 302) In case that the received data is not a calling party's telephone number (step ST 303), the received data is transferred to the handset side CPU 305 b The CPU 305 b at the handset displays the received data to the display part 307 (step ST 304), rings the speaker 363 for a specified period of time and informs an operator of the calling (step ST 305).

In case that at the step ST 303, the number is a calling party's telephone number, the received data is transferred to the region specified as a calling telephone number area within the memory 306 (step ST 306).

Then, the received data is transferred to the CPU 305 b at the handset side In addition, an instruction is applied to the power supply control part 362 a and then a power is supplied to each of the blocks within the dotted line-of Fig 10 not yet energized (step ST 309).

CPU 305 b at the handset may display on part 307 a calling party's telephone number under the same condition as if it was inputted from the keyboard 309 (step ST 307).

Then, the speaker 363 is rung (step ST 308).

Under this condition, as the transmitting (SEND) key at the operation part 308 is depressed, CPU 305 b at the handset acknowledges the depressed condition and stops the ringing of the speaker 363 In addition, an instruction is given to the power supply control part 363 b to cause the non-energized blocks within the dotted line at the handset 391 to be connected to the external battery so as to supply power thereto (step ST 309) In this way, preparation for calling operation is completed for the calling party's telephone number Thereafter, in the same manner as that of the first preferred embodiment of Fig SA, the calling party's telephone number is used to place a call to that party (steps ST 310 and ST 312), and the operator conducts a conversation (step ST 313) After completion of conversation (step ST 314), CPU 305 a at the main body and CPU 305 b at the handset give an instruction to each of the power supply control parts 362 a and 362 b, respectively, so as to shut off power to the portion of the telephone enclosed by the dotted line in Fig 10 from the externalbattery (step ST 316).

With the constitution shown in Fig 10, one having a voice responding part 320 similar to part 120 in Fig.

7 is illustrated Even if this is not present, it may provide a similar effect.

If the configuration shown in Fig 10 is used, in the same manner as those of the second and third preferred embodiments, if the transmitting (SEND) key is not depressed at the step ST 310 within a specified period of time, more effective processing can be attained That is to say, in the same manner as that of the second preferred embodiment, CPU 305 a at the main body may execute the instantaneous calling program after an-elapse of the specified period of time, the calling party's telephone number is used to call it and then the voice responding program is executed to output a message within the ROM of the voice responding party 320 to the voice signal processing part 358 In addition, in the same manner as that of the third preferred embodiment, transferring means may also be applied to the CPU 305 at the handset and Cp U 305 a at the main body In this case, CPU 305 b at the handset takes the transferring telephone number from the operation part 308 in advance and transfers it to CPU 305 a at the main body Then, CPU 305 a at the main body stores the transferring telephone number in a predetermined region in the memory 306 At the step ST 310 in Fig 11, after a specified period of time elapses, CPU 305 a at the main body may execute the transferring program to call up the transferring party and execute a voice responding program, resulting in the calling party's telephone number being sent as a voice message.

Since the mobile telephone device to be installed in a vehicle is operated as described above, even if a period during which the battery is not charged with electrical power is extended for a long period of time, it is possible to minimize consumption of the battery mounted in the vehicle If either the instantaneous calling means or transferring means is provided, transmitting and receiving of a message can be performed even if an operator is not present.
