FIG. 5 is a block diagram showing the internal configuration of the mobile phone according to the present invention. A QPSK-modulated radio frequency signal transmitted from a base station (not shown) via a digital communication channel is received by an antenna 101 and then received by a receiving circuit (R) via an antenna duplexer (DIU) 102.
X) 103 is input. This receiving circuit (RX) 103
Converts the radio frequency signal into a frequency synthesizer circuit (SY
N) The signal is mixed with the reception local oscillation signal generated from 104, frequency-converted to an intermediate frequency signal, and then amplified and quadrature demodulated. The frequency of the reception local oscillation signal generated from the frequency synthesizer circuit 104 is controlled by the control circuit 1
Instructed by a control signal CONT output from 23.

The received intermediate frequency signal is supplied to the A / D converter 1
After being converted into a digital signal by 06, it is input to a digital modulation / demodulation circuit (MODEM) 108. The digital modulation / demodulation circuit 108 performs delay detection of the received intermediate frequency signal, and further performs digital demodulation by establishing frame synchronization and detection of a color code signal to convert the signal into a digital baseband signal.

The digital baseband signal output from the digital modulation / demodulation circuit 108 includes a digital communication signal and a digital control signal. Among them, the digital control signal is taken into the control circuit 123 and identified.
On the other hand, the digital communication signal is transmitted to an error correction code decoding circuit (C
H-CODEC (channel codec) 109 is input. The error correction code decoding circuit 109 performs deinterleaving and error correction decoding processing on the digital communication signal supplied from the digital modulation / demodulation circuit 108. When the digital communication signal is inputted to a code decoding circuit (SP-CODEC: speech codec) 110 and the digital communication signal is character information or melody attached character information, the control circuit 123
Is input to

The speech codec 110 performs speech decoding on the digital speech signal. The speech signal output from the speech codec 110 is D
After being converted into an analog call signal by the / A converter 114,
The signal is amplified by the receiving amplifier 118 and output from the speaker 119.

On the other hand, the transmission signal of the speaker collected by the microphone 121 and subjected to sound-electric conversion is transmitted to the transmission amplifier 120.
After that, the signal is converted into a digital transmission signal by the A / D converter 115 and input to the speech codec 110. The voice codec 110 performs voice coding on the digital voice signal. The digital voice signal output from the voice codec 110 is a digital control signal output from the control circuit 123. The signal is input to the error correction decoding circuit 109 together with the signal. The error correction decoding circuit 109 converts the digital transmission signal and the digital control signal into a digital baseband signal by performing an error correction encoding process and an interleave process, and converts the digital baseband signal after the encoding. Is input to the digital modulation / demodulation circuit 108. When character information and melody attached character information are sent from the control circuit 123, they are processed as digital transmission signals.

The digital modulation / demodulation circuit 108 adds a frame signal and a color code signal to the digital baseband signal from the error correction code decoding circuit 109 and further performs signal mapping processing.
The output of the digital modulation / demodulation circuit 108 is converted into an analog signal by the D / A converter 107 and input to the transmission circuit (TX) 105. The transmitting circuit 105 quadrature-modulates the baseband signal converted to the analog signal, and further synthesizes the
The signal is mixed with the local oscillation signal generated in step 4, converted to a predetermined transmission frequency, and amplified. The transmission signal is sent to the antenna 101 via the antenna duplexer 102, and transmitted from the antenna 101 to the base station as a radio wave. Sent out.

The digital modulation / demodulation circuit 108, error correction code decoding circuit 109, and voice code decoding circuit 110 are connected to a control bus 111. The control bus 111 is a parallel bus signal line and controls interfaces of various circuit units. The control bus 111 further includes a control circuit 123, a CPU 129, a ROM 130, a RAM 13
1 is connected.

The control circuit 123 controls the circuits connected to the control bus 111 based on the clock signal from the oscillation circuit 128, controls the display of the liquid crystal display unit 2, and operates the key unit (KEY) 125. It performs input processing.

Here, the liquid crystal display unit 2 displays a telephone number and a content. The key unit 125 includes numeric keys and function keys including the above-described pair of keyboards 3A and 3B and the pair of side keyboards 6A and 6B. When the user performs an input operation of these keys, a telephone number, a call, an end Capture information such as talk, characters, codes, and function settings.

The control circuit 123 includes a tone generator for generating a ring tone and a melody tone. The tone output is amplified by the amplifier 126 and output from the speaker 127.

On the other hand, the ROM 130 is a flash ROM
Or, it is constituted by an EEPROM, and in addition to various programs of the portable radio telephone, fixed character information, fixed melody information, correspondence between fixed character information and fixed melody information, individual information, adjustment information of the wireless device, etc. are stored in advance. used. The CPU 129 fetches and executes a corresponding program from the ROM 130 according to an instruction from the control circuit 123. The RAM 131 is constituted by, for example, a flash memory, and retains stored information even when the power of the device is not turned on by a backup battery (not shown). While storing the converted recording signal,
It is used to store character information and melody information input by the user.

Each of the above circuit blocks has a battery 1
The output of 33 is stabilized by the stabilized power supply circuit 132 and supplied as power.

FIG. 7 is a diagram showing a processing flow of assigning browser operation keys by the control circuit 123 described above. When using the browser function on the Internet, first, in step S10, the content is downloaded from the Internet. Next, in step S11, the shape of the downloaded content is checked, and it is determined whether the display mode on the liquid crystal display unit 2 is a normal display mode or a display mode that is long in the left-right direction. If the display mode is long in the left-right direction, a pair of side keyboards 6 assigned as volume keys when the telephone function is used.
A function as a browser operation key is assigned to A and 6B (step S13). If it is determined in step S11 that the display is the normal display, a function as a browser operation key is assigned to the pair of keyboards 3A and 3B below the liquid crystal display unit 2 (step S12).

In the above example, the mobile phone body 1 automatically sets which key is to be assigned to the browser operation key according to the display mode of the content. A display asking "Do you want to assign the volume key to the browser operation key?" May be output to the liquid crystal display unit 2 to allow the user to make a determination.

Further, in the above description, the embodiment in which the content downloaded from the Internet is displayed by the browser function has been described. However, the present invention is not limited to the above example, and game software recorded on a recording medium or the like is read as content. The present invention can also be applied to a case where a display is made on the liquid crystal display unit 2.
