[0006]

By the way, the wireless telephones used in these systems monitor the arrival of a wireless incoming signal from the base station or the connection device in the standby state, and receive the wireless incoming signal addressed to itself. When a signal is received, the user is informed that an incoming call has occurred by causing a sounding body such as a speaker provided in the wireless telephone to generate a sound. However,
Recently, this type of wireless telephone has become smaller and lighter due to the progress of integrated circuit technology and the like, and it has come to be easily accommodated in a pocket of a user's clothes or a bag. For this reason, when an incoming call occurs while the wireless telephone is stored in a pocket or bag of clothes, when the user is in a place with a lot of ambient noise, such as on a road with heavy traffic or at a construction site, a ringing sound is generated. It was extremely unfavorable because the user did not hear and did not notice the incoming call.

Further, the ringing volume is also set to be high so that the user can be notified of the arrival of an incoming call even in a place where the ambient noise is large. However, in such a case, a large current is consumed to generate a large ringing tone, and as a result, the power consumption of the wireless telephone increases and the battery life is shortened, which is extremely undesirable.

The present invention has been made in view of the above circumstances, and an object of the present invention is to constantly notify the occurrence of an incoming call clearly regardless of the use condition so as to improve the notification performance and to move. It is an object of the present invention to provide a portable mobile radio communication device capable of suppressing the increase in size of the radio communication device main body and an increase in power consumption and maintaining a long battery life, and an incoming call notification auxiliary device thereof.

[0009]

In order to achieve the above object, the present invention provides a portable mobile radio communication device or an incoming call notification auxiliary device which is separate from the communication device main body, and the portable mobile radio communication is provided. The device or its device body is provided with signal output means for generating an incoming call notification signal and outputting it to the outside when a wireless incoming signal addressed to the device itself is received, and the incoming call notification auxiliary device is A vibration for notifying an incoming call from the vibration generating means is provided according to the incoming call notification signal taken in by the signal input means, and a signal input means for taking in the incoming call notification signal outputted from the signal output means. And has its own battery power supply so that at least the vibration generating means can be operated by the operating voltage generated by this battery power supply. That.

[0010]

As a result, according to the present invention, when an incoming call occurs, an incoming call notification signal is supplied from the portable mobile communication device or its main body to the incoming call notification auxiliary device, and the incoming call notification auxiliary device generates a vibration for incoming call notification. Will occur. Therefore, for example, if the user wears the incoming call notification assisting device, even if an incoming call occurs in a situation where the ringing sound is hard to hear due to a large ambient noise, the incoming call assisting device vibrates to cause an incoming call. You can know the occurrence.

Further, it is not necessary for the portable mobile radio communication device or its device body to generate a ringing sound at a high volume, and the incoming call notification assisting device performs a vibration generating operation by its own battery power source. Therefore, the life of the battery power source of the portable mobile radio communication device or the main body of the device can be maintained for a long period of time, whereby a compact mobile radio communication device having a long continuous use time can be provided.

EXAMPLES The present invention will be described below based on examples. FIG. 1 shows the configuration of a portable wireless telephone device according to an embodiment of the present invention, where AS1 is a wireless telephone and BS1 is an incoming call notification auxiliary unit.

First, in the radio telephone AS1, a radio communication signal transmitted from a base station (not shown) in a predetermined time slot of a radio channel which is being selectively set is received via a receiving circuit (RX) via an antenna 1 and a duplexer (DUP) 2. ) 3, where it is combined with the local oscillation signal output from the frequency synthesizer (SYN) 4 and converted into an intermediate frequency signal. The received intermediate frequency signal is digitally demodulated after frame synchronization and bit synchronization are established by the digital modulation / demodulation circuit (MOD) 6. still,
The synchronization signal obtained by the frame synchronization and the bit synchronization is supplied to the control circuit (CONT) 11. The digital demodulated signal output from the digital modulation / demodulation circuit 6 is subjected to signal equalization of a demodulation waveform by an equalizer (not shown), and then error correction decoded by an error correction code decoding circuit (CH-COD) 7. . Here, the digital demodulated signal output from the error correction code decoding circuit 7 includes a digital speech signal and a digital control signal, of which the digital control signal is supplied to the control circuit 11 for identification. On the other hand, the digital speech signal is sent to the voice code decoding circuit (S
After being decoded by the P-COD) 8 and converted back into an analog speech signal, it is supplied to the handset 9 and outputted from the handset 9 in a loud voice.

On the other hand, the transmitted voice of the speaker is the transmitter 10.
After being collected by and converted into a transmission signal, it is first encoded in the voice code decoding circuit 8. Then, the digital transmission signal obtained by this encoding is subjected to error correction coding in the error correction code decoding circuit 7 together with the digital control signal output from the control circuit 11, and then input to the digital modulation / demodulation circuit 6. The digital modulation / demodulation circuit 6 generates a modulated signal of an intermediate frequency according to the digital transmission signal supplied from the error correction code decoding circuit 7 and inputs it to the transmission circuit (TX) 5. In the transmission circuit 5, the modulated signal is combined with the local oscillation signal output from the frequency synthesizer 4 and converted into a high frequency signal. This high frequency signal is high frequency amplified and then passed through the duplexer 2 to the antenna 1
Is transmitted from the base station to the base station.

By the way, the control circuit 11 is provided with, for example, a microcomputer as a main control unit, and has an incoming call notification control means in addition to a function of performing various controls related to selection and setting of a wireless channel. . The incoming call notification control means generates the incoming call notification signal OS when it determines that the received digital control signal is the incoming call signal and that the incoming call signal is addressed to itself. The incoming call notification signal OS is supplied to the ringing drive circuit 12.
The ringing drive circuit 12 generates a ringing drive signal according to the incoming call notification signal OS and supplies the ringing drive signal to the sounder 13, thereby causing the sounder 13 to generate a ringing tone.

Reference numeral 14 is a console unit (CU)
Therefore, switches such as a transmission switch and a dial switch, and indicators such as a light emitting diode and a liquid crystal display are provided. Reference numeral 15 is a power supply circuit, which generates a predetermined operating voltage Vcc based on the output voltage of the battery 16 and supplies it to the above circuits.

On the other hand, the incoming call notification signal OS output from the control circuit 1 is input to the incoming call notification auxiliary unit BS1 via the connector terminal 17 and the connection cable 30 connected to the connector terminal 17, respectively. The incoming call notification auxiliary unit BS1 is formed in a pen shape so that it can be inserted into, for example, a chest pocket of a user's clothing, and includes a vibrator 21, a vibration drive circuit 22 for driving the vibrator 21, and a connector terminal 23. ing. The incoming call notification signal OS is fetched via the connector terminal 23. The vibration driving circuit 22 vibrates the vibrator 21 in accordance with the incoming call notification signal OS received via the connector terminal 23.

The incoming call notification auxiliary unit BS1 has its own power supply circuit 24 and battery 25. The power supply circuit 24 generates a predetermined operating voltage VDD based on the output of the battery 25, and supplies the operating voltage VDD to the vibrator 21 and the drive circuit 22.

Next, the operation of the apparatus configured as described above will be described.

In the standby state, the wireless telephone AS1 monitors whether or not a wireless incoming signal addressed to itself has arrived from the base station. In this state, when a wireless incoming signal addressed to the own device is detected, the control circuit 11 of the wireless telephone AS1
The incoming call notification signal OS is generated from
S is input to the ring drive circuit 12. Therefore, a ringing drive signal is generated from the ringing drive circuit 12, and the sounder 13
As a result, the sounder 13 outputs a ringing sound in a loud voice.

On the other hand, suppose that the incoming call notification auxiliary unit BS is temporarily connected to the wireless telephone AS1 via the connection cable 30.

Then, the incoming call notification signal OS is transmitted from the connector terminal 17 of the wireless telephone AS1 to the connection cable 30 and the connector terminal 23.
Is input to the vibration drive circuit 22 of the incoming call notification auxiliary unit BS1. Therefore, the vibration drive circuit 22
Generates a vibration drive signal and supplies it to the vibrator 21. As a result, the vibrator 21 vibrates.

Therefore, at this time, the user is notified of the occurrence of the incoming call by the ringing sound generated from the wireless telephone AS1 and the vibration of the incoming call notification auxiliary unit BS1. For this reason, even if the user does not hear the ringing sound because the user is in a place with high ambient noise, such as a construction site, and the wireless telephone is housed in the back of a pocket of clothes, the incoming call notification is given. The vibration of the auxiliary unit BS1 makes it possible to reliably know the occurrence of an incoming call.

The incoming call notification auxiliary unit BS1 has its own battery 25 and power supply circuit 24, and the vibrator 2 is driven by the operating voltage VDD generated by these.
1 is driven, there is no concern that the power consumption of the battery 16 of the wireless telephone AS1 will increase due to the occurrence of the vibration. Therefore, the battery life of the wireless telephone AS1 can be maintained for a long period of time, and a long continuous use time can be secured by using a small battery.

In the transmission circuit 18, the carrier wave is the incoming call notification signal OS.
Is modulated by AM or FM and wirelessly transmitted from the antenna 19. At this time, as the frequency of the carrier wave, a frequency different from the frequency used for wireless communication between a base station (not shown) and the wireless telephone AS3 is used.
And the transmission level is set weak. A reception circuit (RRX) 26 having an antenna 27 is provided in the incoming call notification auxiliary unit BS3. The reception circuit 26 receives the modulated wave transmitted from the transmission circuit 18 of the radio telephone AS3 and demodulates the incoming call notification signal. Then, the demodulated incoming call notification signal is transmitted to the vibration drive circuit 22.
And the vibrator 21 is vibrated. With such a configuration, the connection cable 30 for connecting the wireless telephone AS3 and the incoming call notification auxiliary unit BS3 can be eliminated, so that the connection cable 30 can be omitted.
Thus, it is possible to prevent the action of the user from being restricted, and to prevent the malfunction of the incoming call notification auxiliary unit BS1 due to the disconnection of the connection cable 30 or the poor contact between the connector terminals 17 and 23. That is, handling and reliability can be improved.

Further, in the above embodiment, when an incoming call occurs, the wireless telephone AS1 produces a ringing sound, and at the same time, the incoming call notification auxiliary unit BS1 produces a vibration. In the state where the unit BS1 is connected, the generation of the ringing sound may be stopped. For example, by providing a detector for detecting the presence or absence of the connection of the connection cable 30 in the wireless telephone AS1 and turning on / off the supply of the incoming call notification signal from the control circuit 11 to the ring drive circuit 12 according to the detection output of the detector. realizable.
