BACKGROUND OF THE INVENTION

This invention relates to a portable telephone which transmits data having at least one of a voice signal and an image datum which are radio signals to a communicating device through a base station, and which receives the data having at least one of the voice signal and the image datum from the communicating device through the base station.

Recently, image transmission becomes important in accordance with development of communication technology. Therefore, various terminal devices which can execute image transmission are provided. In addition, a conventional portable telephone of the type comprises a body, an antenna, an operation device, a speaker, a display device, a microphone, a camera, a transmitting and receiving device, a controlling device, and amplifiers. The antenna is attached to the body. The operation device, the speaker, the display device, the microphone, and the camera are mounted on the body.

Also, according to development of communication technology, facsimile service that where a facsimile device requests and receives a necessary datum is executed. Also, push-phone service such as preengagement pre-engagement of an airline ticket and remainder inquiry of a bank deposit is are executed. In these services, a user transmits, by operating ten keys of a telephone, datum of a predetermined telephone number to one of these service systems to connect the telephone to the one of these service systems. Thereafter, the user operates the ten keys of the telephone, in response to a guidance message, to transmit data of such as a number (BOX number) representing a datum which is needs needed for a DTMF signal, an account number, and a preengagement time. Thereby, the user can obtain data.

However, in the portable telephone, there is a problem that facility of operation is wrong. This is because, since the handset of the portable telephone is integrated with ten keys, the user cups the portable telephone to the user's ear when the user hear hears the guidance messages and the user disconnect removes the portable telephone from the user's ear when the user operates the ten keys. Also, in the portable telephone, there is another problem that the user is hardly able to hear a voice from the speaker when the user disconnect removes the portable telephone from the user's ear to operate the ten keys. In addition, in the portable telephone, there is still another problem that it is needs to set, by such as by a switching circuit, a hands free mode in case that the user executes conservation while the user see sees image data which is displayed.

Referring to FIG. 3, the controlling device 9 comprises a main controlling section 12, a substitute controlling section 13, and a baseband section 14. The substitute controlling section 13 chiefly executes monitor of a power supply voltage, monitor of installation of a battery charger, monitor of keyed input and reset control of a power supply of the main controlling section 12. The substitute controlling section 13 is implemented by a substitute microcomputer which has ROMs and RAMs. The substitute microcomputer is operated by a main system clock signal having 2.45 MHz and a substitute system clock signal having 32.0 KHz. Initially, the substitute microcomputer is operated by the main system clock signal having 2.45 MHz. After the substitute system clock signal has the stable 32.0 KHz, the substitute microcomputer is operated by the substitute system clock signal instead of the main system clock signal and the substitute microcomputer stops to produce the main system clock signal. Thereby, it is possible to decrease consumption electric power.

The main controlling section 12 is implemented by a main microcomputer 14, a flash ROM 15 16, a SRAM 16 15, a an EEPROM 17, and these peripheral circuits. The main microcomputer executes such as , for example, control of the transmitting and receiving device 8, control of the speaker 4, control of the amplifier 10, control of the microphone 6, control of the amplifier 11, control of the display device 5, and monitor of keyed input through the substitute controlling section 13. The main microcomputer 14 has such as , for example, input and output terminals, serial interfaces, a timer, and an interrupt controller. The main computer 14 is operated by a clock signal having 16 MHz. The main microcomputer 14 controls parts of the portable telephone. A program of the flash ROM 15 16 is able to be rewritten by an outside device through an outside interface connector.

The baseband section 15 18 is implemented by such as , for example, a modulating and demodulating section, a channel codec section, a radio controlling section, and a voice processing section. The baseband section 15 18 receives the amplified transmitting voice signal from the microphone 6 through the amplifier 11 and encodes, the PCM and ADPCM, the amplified transmitting voice signal to produce a an encoded voice signal. The channel codec section decodes the encoded voice signal to produce and supply the transmitting voice signal to the transmitting and receiving device 8.

Also, the baseband section 15 18 receives the receiving data having at least one of the an image datum and the a voice signal. When the baseband section 15 18 receives the voice signal, the baseband section 14 18 demodulates the voice signal to produce a demodulated voice signal and encodes decodes, by ADPCM and PCM, the demodulated voice signal to produce an encoded a decoded voice signal. The baseband section 15 18 supplies the encoded decoded voice signal, as a voice signal, to the speaker 4 through the amplifier 10. At this time, the controlling device 9 controls the amplifier 10 so that the user can hear, at the first state that the ear is not near to the speaker 4, the voice from the speaker 4 when the data call setting signal from the base station includes the discrimination datum which represents the image datum, namely, in the hands free mode or in the voice enlarging mode. Also, the controlling device 9 controls the amplifier 10 so that the user can hear, at the second state that where the ear is near to the speaker 4, the voice from the speaker 4 when the data signal from the base station does not include the discrimination datum which represents the image datum, in the voice normal mode.

Referring to FIG. 4, an operation of the portable telephone will be described in detail. The portable telephone transmits, at an establishment time of a data link between the base station, the data having at least one of both of the voice signal and the image datum and the discrimination datum which is defined by transmission capacity. The transmission capacity is included in a call setting datum. The transmission capacity represents the data transfer capacity and the data transfer velocity.

The portable telephone transmits, as the octet 3 of the call setting datum, the data transfer capacity. Also, the portable telephone transmits, as the octet 4 of the call setting datum, the data transfer velocity. For example, in the data transfer capacity which is transferred by the octet 3, bit “00000” represents voice, bit “01000” represents data of 32K, bit “01001” represents data of 64K, bit “10000” represents audio of 3.1K, and other bits represent data transfer capacities which are predetermined. For example, in the data transfer velocity which is transferred by the octet 4, but “00111” represents transfer velocity of 8 kbit/s, bit “01010” represents transfer velocity of 16 kbit/s, bit “01100” represents transfer velocity of 32 kbit/s, bit “10000” represents transfer velocity of 64 kbit/s, and other bits represent data transfer velocities which are predetermined.

As shown in FIG. 4, when the portable telephone receives a call from the base station, the portable telephone transmits a demand of establishment of link channel to the base station. When the base station receives the demand of establishment of link channel, the base station allocates a channel, as an allocated channel. The base station transmits datum of the allocated channel to the portable telephone. The portable telephone transmits a synchronous bust signal to the base station. The base station transmits another synchronous bust signal to the portable telephone. Next, the portable telephone transmits command of SABM (Set Asynchronous Balanced Mode) to the base station. When the base station receives the command of SABM, the base station transmits response of UA (Unnumbered Acknowledge) to the portable telephone.

When the portable telephone receives the response of UA, the portable telephone transmits a call-accepted signal to the base station. When the base station receives the call-accepted signal, the base station transmits a call setting signal, which includes the transmission capacity, to the portable telephone. When the portable telephone receives call setting signal, the portable telephone transmits a call setting-accepted signal to the base station. Also, the portable telephone transmits the call setting datum which includes the transmission capacity to the base station. When the base station receives the call setting datum, the base station transmits a call setting-accepted signal to the portable telephone.

Referring to FIG. 5, a receiving operation of the portable telephone will be described in detail. At a step S1, the portable telephone judges whether or not the portable telephone receives the data from the base station. When the portable telephone receives the data, at a step S2, the portable telephone judges whether or not the data call setting signal includes the discrimination datum which represents the image datum. When the data signal includes the discrimination datum which represents the image datum, at a step S3, the portable telephone sets the voice enlarging mode, namely, the hands free mode. The voice enlarging mode represents a mode that the controlling device 9 controls the amplifier 10 so that the user can hear, at the first state that where the ear is not near to the speaker 4, voice from the speaker 4.

At the step S2, when the data signal does not include the discrimination datum which represents the image datum, at a step S4, the portable telephone sets the voice normal mode. The voice normal mode represents a mode that he the controlling device 9 controls the amplifier 10 so that the user can hear, at the second state that where the ear is near to the speaker 4, the voice from the speaker 4. A step S5 follows the steps S3 and S4 to judge, by the portable telephone, whether or not a receiving operation is ended. When the receiving operation is not ended, the step S5 returns to the step S2.

Referring to FIGS. 6 and 7, the description will proceed to a portable telephone according to a second embodiment of this invention. Similar parts are designated by like reference numerals.

The portable telephone comprises the body 1, the antenna 2, the operation device 3, the speaker 4, the display device 5, the microphone 6, the camera 7, the transmitting and receiving device 8, the controlling device 9, the amplifiers 10 and 11, a switching circuit 19, and another speaker 20. The switching circuit 19 is connected to the controlling device 9 and to the speakers 4 and 20.

The speaker 4 outputs a first voice when the speaker 4 is supplied with the amplified voice signal from the amplifier 10 so that the user can hear, at the first state that where the ear is not near to the speaker 4, the first voice from the speaker 4 when the data call setting signal from the base station includes the discrimination datum which represents the image datum, namely, in the voice enlarging mode. The speaker 20 outputs a second voice when the speaker 20 is supplied with the voice signal form from the controlling device 9 so that the user can hear, at the second state that where the ear is near to the speaker 20, the second voice from the speaker 20 when the data signal from the base station does not include the discrimination datum which represents the image datum, namely, in the voice normal mode.

The switching circuit 19 selectively supplies, in response to a first control signal and a second control signal, the voice signal to the amplifier 10 (the speaker 4) and the speaker 20. The controlling device produces and supplies the first control signal to the switching circuit 19 when the data signal from the base station includes the discrimination datum which represents the image datum. Also, the controlling device 9 produces and supplies the second control signal to the switching circuit 19 when the data signal from the base station does not include the discrimination datum which represents the image datum.
