2. Description of the Related Art Radiotelephones that perform protocol control using digital data are widely used, for example, as analog portable telephones, digital portable telephones, PHS telephones, and digital cordless telephones. These wireless telephone devices are particularly important as portable telephone devices because they allow wireless communication. In portable telephone devices,
It is required to be small and lightweight as a whole and to have good operability.

Japanese Patent Application Laid-Open No. Hei 10-56503 discloses a portable telephone device which is reduced in size by removing a numeric keypad.
A numeric keypad used for inputting a telephone number or the like requires a certain size in terms of easiness of operation, which is a limitation in miniaturizing a mobile phone device. JP-A-10-5
In the prior art of 6503, the mobile phone body is used only for reception, and when transmitting, a separate DTMF (Dual
Tone MultiFrequency) The DTMF sound is input from the tone dialer to the transmitter of the mobile phone, and a transmission process is performed. DT
In the calling process using the MF tone dialer, it is necessary to first perform an operation of depressing an on-hook / off-hook key provided on the mobile phone body. After the off-hook operation is performed, control is performed to input the DTMF sound of the telephone number output from the DTMF tone dialer from the transmitter, and output the DTMF sound to the radio unit as it is to make a call.

The prior art relating to inputting DTMF sound from a DTMF tone dialer to a microphone is as follows:
It is also disclosed in JP-A-9-18953. In this prior art, a commercially available auto dialer can be effectively used to input a dial number by a push sound. Also, Japanese Utility Model 63-147052 and Japanese Utility Model 63
-147053 discloses a prior art in which a telephone device connected to a dial pulse line is provided with means for converting a DTMF signal from a commercially available DTMF dialer into a dial pulse signal.

JP-A-6-113376 discloses a prior art in which a tone signal is transmitted together with an audio signal by a wireless microphone, and the tone signal is detected to control various devices. Japanese Patent Application Laid-Open No. 6-224997 discloses a prior art in which a DTMF signal is used for controlling various devices.

[0006]

In a radio telephone apparatus which performs protocol control by digital data, an exchange for receiving a dial number is not connected at the time of off-hook. That is, a dial tone, which is an output sound indicating dial acceptance accompanying off-hook, is output inside the wireless telephone device. When the user performs a dial operation using a numeric keypad or the like in accordance with the dial tone, dial information corresponding to the dial operation is received, and this information is incorporated as part of a call setup message as digital data and transferred to the exchange. Therefore, even if the user simply performs an off-hook operation and confirms the occurrence of a dial tone and inputs a DTMF tone, the actual connection operation does not occur. This is because the calling operation is output to the exchange as a digital command and is handled as digital data in the exchange of the communication protocol. Therefore, in a wireless communication device using a connection protocol based on digital data, a beeper such as an auto dialer cannot be used for dial operation for starting a call.

Further, in the prior art of Japanese Patent Application Laid-Open No. H10-56503, a call operation is performed by an on-hook /
Operate off-hook key, dial operation is DTM
Since the operation is performed by operating the F-tone dialer, it is necessary to operate both devices. When a DTMF receiving function is provided in a telephone device so that a conventional DTMF tone dialer can be used, noise including DTMF sounds used in other telephones is filled around the telephone device. Occasionally, noise may cause malfunction.

Further, in a telephone device provided with a cover such as a flip, it is necessary to open the flip or the like so that the microphone can be used. In addition, if it is necessary to operate the on-hook / off-hook key in order to be able to receive the DTMF sound from the DTMF tone dialer, the operation becomes complicated in two steps. Also, if a DTMF sound is input during a call, the DTMF sound may be heard by the other party, which may cause discomfort. For this reason D
When a sound command such as a TMF sound is detected, mute may be applied. However, the first sound determined as a sound command is transmitted to the other party as a sound during a call. For this reason, the other party can determine that a sound command has been input, and the audible sound command signal may be eavesdropped by a third party. Further, if a sound signal input to the microphone is mixed into the sound command signal, the sound command signal becomes noise and may cause a malfunction.

The prior art disclosed in Japanese Patent Application Laid-Open No. 9-18953 is
It is not possible to input DTMF signals or tone signals due to the small size of the wireless telephone device, but it is possible to use a DTMF tone dialer to input telephone numbers, etc. Has become.

It is an object of the present invention to provide a wireless telephone device that can be downsized without impairing command input operability for performing control using sound that can be input together with an audio signal.

FIG. 5 shows the telephone 2b of the embodiment of FIG.
The operation when applied to a PDC telephone, which is a domestic digital portable car telephone system, will be described. At time t1, first, the user sets the telephone 2b so that the DTMF sound input becomes valid.
Flip 9 is opened. The opening of the flip 9 is detected by the CPU 34, for example, when a projection on the flip 9 releases a switch provided on the main body of the telephone 2b. After the detection, the CPU 34 sets the DTMF receiver 3
1 is enabled, and an input to the microphone 30 is awaited. The user then outputs the destination telephone number from the command generator 1 after time t2. Command generator 1
Selects, for example, one of the telephone numbers stored in advance in the memory 22 in accordance with the operation of the user interface 20, generates the DTMF in the DTMF generator 21, and outputs
Output as TMF sound. The generation of the DTMF sound is to apply a DTMF sound to a conventional analog telephone line through a microphone of a telephone and to transmit a dial signal to an exchange. Done to meet. For example, the signal transmission time is 50 milliseconds or more, the minimum pause, which is the silence time between DTMF sounds of each digit, is 30 milliseconds or more, and the total cycle of these is 120 milliseconds or more. In the case of the present embodiment, the telephone set 2b which has received the sequence of each digit of the telephone number by the DTMF sound transmits the sequence to the DTMF receiver 3.
The data is converted into number data by 1 and temporarily stored in the memory 42.

The telephone 2b receiving the number inputs the DTMF when the number of received digits reaches the specified number of digits or when a call is issued.
The transmission operation at time t3 is performed when receiving a sound, when instructing with a transmission button or the like, or when there is no input of the next telephone number for a predetermined time, for example, 20 seconds or more. As the specified number of digits, reception of 10 digits including the area code, “10
Receiving three digits of special numbers such as "4", 10 for mobile phones
Alternatively, reception of 11 digits may be considered.

In the transmitting operation, first, random access transmission is performed on a predetermined channel, and a message including a transmitting radio state report and a call setting is transmitted. The call setting message includes information obtained by performing predetermined processing on the telephone number information received from the command generator 1. Table 1 below shows the structure of a call setup message.

[0046]

[Table 1]

This message includes a called number information element as shown in the following Table 2 in order to transfer called number information from the user who is the user to the telephone network.

[0048]

[Table 2]

In Table 2, the i-th numeral indicates the telephone number represented by the number digit shown in Table 3 below. Note that the number digit bit position includes two upper bits of bit positions 8 to 5 and four lower bits of bit positions 4 to 1 in one octet of 8 bits.

[0050]

[Table 3]

The telephone network that has received the call setting message returns a call setting acceptance message to the telephone 2b at time t4. On the other hand, the telephone network extracts the telephone number from the called number information element in the call setup message and starts the network connection, which is a telephone connection operation. Time t6 for the authentication request at time t5
Is confirmed that the telephone 2b is an authorized user. After time t7, SB1 is repeatedly transmitted from the telephone network through the communication channel, and the wireless channel used for the communication is specified on the control channel. Phone 2 at time t8
When b transmits SB2, SB3 and SB4 are exchanged, and synchronization is established. As a result of the routing performed in parallel with this, when a call of the other party is made at time t9, the telephone network sends a call message to the telephone set 2b, and the telephone set 2b generates a ringing tone to call the user. Tell that. When the other party answers, a response message is sent from the telephone network to the telephone 2b at time t10, and the telephone 2b
Returns a response confirmation message, connects the voice for the first time, and shifts to the call state. As described above, when the digital connection protocol is used, an audio signal from the telephone set 2b serving as a terminal is often not transmitted to the telephone network until the communication state starts.
Transmission control using the TMF sound is possible as described above.

In the embodiment shown in FIG. 1, since the telephone network is connected by using the DTMF sound, a conventionally used DTMF generator such as a DTMF tone dialer can be effectively used as it is. However, DTMF sounds composed of audible sounds may be quite widespread, and human beings can understand the contents of the DTMF sounds. Therefore, a low-speed modem signal or the like can be used as the command sound without using the DTMF sound. Even if the DTMF sound is used, if the correspondence between the standard correspondence and data different from the standard correspondence is set in both the command generator 1 and the telephone 2, the contents can be easily understood only by listening to the sound. And cannot be eavesdropped. In this case, since the mobile phone always dials from the area code, if the sound of "0" indicating the head of the area code is not pronounced first,
It is easy to notice that the correspondence between sounds has changed.
Therefore, if the DTMF sound of “0” is set to the standard correspondence and another correspondence is changed, it is possible to prevent the user from easily noticing that the correspondence has been changed.

For example, if the correspondence shown in Table 5 is used for the standard correspondence between two frequency combinations and data shown in Table 4 below, data "0" is shared and Other data can be exchanged.

[0054]

[Table 4]

[0055]

[Table 5]

When a call is held during communication, a third communication partner is called, and a three-party call is performed, control can be performed by inputting a DTMF sound from the command generator 1. In this case, since a DTMF sound is input during a call, it is preferable to perform mute control to cut off or greatly attenuate the audio system.

FIG. 6 shows a time division multiplot (TDMA).
The timing of mute control when the telephone 2b is used as a PDC mobile phone adopting “le Access: time division multiple access” is shown. In the PDC system, 40 milliseconds is a unit time for performing audio processing, and is equal to the TDMA frame time. When the sound is input to the microphone 30, the sound is sampled by the audio encoder 32, converted from analog to digital, and stored in a buffer memory in the audio encoder 32 during a processing unit of 40 milliseconds per frame. DTM
The F sound is input from the microphone 30 asynchronously with the processing unit. The presence or absence of the DTMF sound is determined by the DTMF receiver 31.

When the DTMF sound is input in the frame numbers 2 to 4, the DTMF receiver 3
From 1, a sound presence determination is generated. At frame number 4, a sound absence determination is generated. The audio processing is started after the sound is sampled for one frame, and is performed intermittently over a period indicated as 0, 1,... The data after the audio processing is interleaved by half. For example, half of frame number 0 and half of frame number 1 are transmitted as one TDMA frame indicated as “0, 1 transmission”. At the time of frame number 3 where it is determined that there is sound, the data of frame number 2 has not been transmitted yet, and remains in the buffer memory.
Therefore, by performing mute processing on this data, the sound from frame number 2 can be muted, and the mixed DTMF sound can be suppressed. Further, the mute process is continued until the frame number 4 where the sound absence determination is performed, and the voice transmission is performed from the next frame number 5 without performing the mute process. The mute process can be performed by setting a parameter indicating the sound intensity smaller than the actual value or replacing the parameter with mute data prepared separately. An error can be intentionally mixed into the data, and the receiving party can determine that there is an error in the audio data, and can shift to the mute state.

In the embodiment of FIG. 2, the microphone 15 is integrated with the command generator 11, and both the voice and the command sound are sent to the telephone set 12 as a sound signal. Therefore, the mute method for the input to the microphone 15 is different from the embodiment of FIG. Are different. User interface from user is user interface 2
Since it is known in advance that the DTMF sound is output from the DTMF generation unit 21 when the DTMF sound is output to 0, the mute of the system of the microphone 15 can be performed by disconnecting the switch 46 from the microphone 15 when the DTMF sound is generated. Change switch 46 from microphone 15 to DTM
Connected to the F generator 21 to output DTMF sound to the telephone 12 and, after the end, switch the changeover switch 46 again to the microphone 15.
Side, the sound input to the microphone 15 can be sent to the telephone 12. By this operation, DTM
Since the voice is not transmitted to the telephone when the F sound is generated, DT
Noise (voice) other than the DTMF sound is not transmitted to the MF receiver 31, and the DTMF determination can be performed well.

[0060]

As described above, according to the present invention, it is possible to control by a sound command in a wireless telephone device which performs protocol control by digital data and connects to an exchange or the like. By reducing the number of operation keys and the like, the size can be reduced.

According to the present invention, since the DTMF signal is used as the sound command signal, the widely used DTMF signal is used.
An F-tone dialer or the like can be used effectively.

Further, according to the present invention, since the control unit is provided with the permissible operation means for permitting the control based on the sound command signal, the control based on the sound command signal can be performed in an environment where the surrounding noise is small.

According to the present invention, since the prohibition operation means for prohibiting the control according to the sound command signal is provided, it is possible to prohibit the control according to the sound command signal in an environment where ambient noise is large.

Further, according to the present invention, by opening and closing the flip provided in the telephone body, the permission and the inhibition according to the sound command signal can be controlled respectively. When the flip is opened, control in accordance with the sound command can be performed, so that a sound command signal can be input from the sound command generator to an input unit such as a microphone of the telephone body to perform various controls.

Further, according to the present invention, since the sound command generator and the telephone body can change and input a sound corresponding to the information represented by the sound command to be generated, the sound command signal is transmitted to the other party or to the other party. Even if heard by three parties, the contents of the control can be kept secret.

Further, according to the present invention, since the sound corresponding to the predetermined information is not changed, a sound such as "0" which is easy to understand is not changed as a whole, and is not changed as a whole. Such an impression can be given.

Further, according to the present invention, since the sound command generator is provided with the microphone, it is possible to make a call using the sound command generator. Since the sound command generator is provided separately from the telephone main body, if the telephone main body performs an electrical process necessary for wireless communication, it can be operated with a small battery. As a result, the sound command generator can be formed in a shape that does not make the user feel uncomfortable even when worn on the head, and various voice inputs such as a hat type, an eyeglass type, a goggle type, and a hearing aid type can be performed.

Further, according to the present invention, the sound signal can be muted when the sound command signal is generated, so that the sound command signal can be input to the telephone body without the signal input to the microphone becoming noise. it can.

According to the present invention, when a sound command signal is detected during a call, the transmission voice signal is muted.
