Abstract

PROBLEM TO BE SOLVED: To disable outgoing and incoming calls by manually and surely setting a mobile communication terminal to a power supply stop lock state and to prevent radio wave interference from occurring when a user thinks that he should restrain himself from making outgoing and incoming calls. SOLUTION: A lock switch 27 is set to a terminal a side at the time of entering a hospital, etc. Thereby, because a control terminal 231 of a power supply switch 23 is cut off from a power key switch 25, and also because the terminal 231 becomes open, the switch 23 is set to an off state, power is not supplied to a radio transmitting and receiving part 50 from a direct current power source 26 through regulators 20 and 21, the part 50 does not operate and outgoing and incoming calls are disabled. Furthermore, even if the switch 25 is turned on with this state, the terminal 231 of the switch 23 does not reach a ground level, the switch 23 is kept to the off state, and the power supply stop state to the part 50 is locked.

, And is input to the channel codec unit 4. A signal of a required time slot is extracted from the demodulated compressed audio signal by the channel codec unit 4, and ADPCM conversion and PCM conversion are further performed by the speech codec unit 5 to be converted into an analog audio signal. This analog audio signal is amplified by the amplifier 6 and output from the speaker 7.

[0003] The analog audio signal input from the microphone 8 is converted into a digital signal by PCM conversion in the speech codec unit 5, and further converted by ADPCM conversion.
The data is compression-converted and input to the channel codec unit 4. The channel codec section 4 inserts the input ADPCM voice signal into the assigned predetermined time slot, and modulates the signal by the modem 3. The transmitting and receiving unit 2 transmits the modulated signal input from the modem 3 from the antenna 1.

The RF control unit 9 controls the modulation and demodulation of the modem 3 and the transmission and reception frequency of the transmission and reception unit 2. The control control unit 10 performs comprehensive control during transmission and reception. Is performed using programs and data stored in the ROM 13 and the RAM 12. The sub CPU 16 is a key unit 1

FIG. 3 is a diagram showing a connection relationship between the mobile communication terminal shown in FIG. An external antenna 47 is provided outside the building 48 (eg, on the roof).
Is erected. External antenna 47 is coaxial cable 4
It is connected to a connection box 49 provided on the inner wall surface of the building 48 by 71 or the like. Therefore, the mobile communication terminal 80 is detachably connected to the connection box 49 via the cable 34 described above, so that the mobile communication terminal 80
And the external antenna 47 are electrically connected. However, the cable 34 and the connection box 49 are connected by a standardized general-purpose connector or the like.

Next, the operation of this embodiment will be described. When the user sets the lock switch 27 to the terminal b side,
Since the control terminal 231 of the power supply switch 23 is opened, the power supply switch 23 is turned off, so that power is not supplied from the DC power supply 26 to each part of the mobile communication terminal, and the mobile communication terminal performs an outgoing / incoming operation. Stops completely. Hereinafter, a method for making and receiving a call from the mobile communication terminal in a state where the mobile communication terminal according to the present embodiment is locked in the power-off state and does not cause radio interference to surrounding devices will be described. In this case, when the pins of the cable 34 for connecting the external antenna are inserted into the antenna connector 33 as shown in FIG. 2, the switch SW is turned off and the connection between the transmitting / receiving section 2 and the internal antenna 1 is cut off. The external antenna 47 installed outside the building 48 as shown in FIG. At the same time, the antenna contact switch 28 is closed and turned on, so that the power key switch 25 and the control terminal 231 of the power supply switch 23 are connected, and the lock switch 27 is turned to the terminal a to release the lock.

In addition, at this time, since the outgoing / incoming call is made by the external antenna 47, the radio wave does not leak into the building 48, and there is no possibility of causing the radio wave interference to other devices. The box 49 is connected by a standardized general-purpose connector or the like.

FIG. 6 is a block diagram showing the configuration of the third embodiment of the mobile communication terminal according to the present invention. In this example, a part of the power supply unit 60 and the control unit 70 is shown, and the other parts are the same as those in the first embodiment. Power supply unit 6 of this example
0 is a switch circuit 64 controlled by the sub CPU 16 between the control terminal 231 of the power supply switch 23 (first switch circuit of claim 3) and the power key switch 25.
(Third switch circuit of claim 3) is inserted.
The sub CPU 16 is connected to a lock key 61 and an unlock key 62 for turning off the power to the wireless transmission / reception unit 50 regardless of the power key switch 25, and further determines whether or not there is a connection to an external antenna (not shown). The antenna connection / separation detection unit 63 to be detected is connected.

Here, the sub CPU 16 constitutes control means, and the lock key 61 and the lock release key 62 constitute a third manual switch.

Next, the operation of this embodiment will be described. In the normal state where the lock key 61 is released, the sub C
The PU 16 turns on the switch circuit 64. Therefore, the power supply key switch 25 is connected to the control terminal 231 of the power supply switch 23. Therefore, the user can supply or stop the power from the power supply unit 60 to the wireless transmission / reception unit 50 by pressing the power key switch 25, and can use the simplified mobile phone function as usual.

When entering a hospital or the like, the user
When 1 is pressed, a current flows from the DC power supply 26 through the diode D1 and the lock key 61, and this becomes a lock signal which is input to the sub CPU 16. Sub C receiving this
The PU 16 turns off the switch circuit 64 and sends the power key switch 2 from the control terminal 231 of the power supply switch 23.
Cut off 5. Thus, regardless of whether the power supply switch 23 is pressed, the control terminal 23 of the power supply switch 23 is
1 is in the open state, and the power supply switch 23 maintains the off state. For this reason, power is not supplied from the power supply unit 60 to the wireless transmission / reception unit 50, and outgoing / incoming / outgoing calls from the portable telephone are impossible. At this time, the sub CPU
Reference numeral 16 indicates on the display unit 19 that the apparatus is in the power-stop lock state and outgoing / incoming is impossible.

Thereafter, when the user leaves the hospital or the like, when the user presses the unlock key 62, a current flows from the DC power supply 26 through the diode D2 and the unlock key 62, and this becomes an unlock signal, which is input to the sub CPU 16. Is done. Upon receiving this, the sub CPU 16 sets the switch circuit 64
Is turned on, and the control terminal 231 of the power supply switch 23 is turned on.
Since the power key switch 25 is connected to the mobile communication terminal to return to the normal state, it is possible to make and receive calls from the mobile communication terminal. At this time, the sub CPU 16 may display on the display unit 19 that the main unit has returned to the normal state.

When it is desired to communicate with the outside in the locked state as described above, communication with the outside can be made by connecting the portable antenna to the external antenna as shown in FIG. In this case, the antenna connection separation detection unit 63
Detects this and notifies the sub CPU 16. Upon receiving this, the sub CPU 16 turns on the switch circuit 64, so that the above-mentioned locked state is released. This allows
When the power key switch 25 is depressed, the power supply switch 23 can be turned on, and a normal incoming / outgoing call can be made. Thereafter, when the communication is terminated and the connection to the external antenna (not shown) is disconnected, the antenna connection separation detecting unit 63 detects this and notifies the sub CPU 16. Upon receiving this, the sub CPU 16 switches the switch circuit 64.
Is turned off, the mobile communication terminal is again in the locked state, and outgoing / incoming is disabled.

This embodiment has the same effects as the second embodiment. In addition, by displaying on the display unit 19 that the apparatus is in the power stop lock state, the user can see this display to confirm that the apparatus is in an outgoing / incoming / outgoing state. You can enter the hospital with confidence. In addition, even when leaving the hospital or the like, since the state of the mobile communication terminal can be confirmed by the above display, the power-stop lock state is surely released to make the mobile communication terminal communicable, thereby improving its convenience. It can be used for

It should be noted that if a configuration for removing the incoming and outgoing calls in the locked state, such as the antenna connection / separation detecting unit 63, is removed, the convenience is slightly reduced. However, similar to the first embodiment of FIG. This has the effect of preventing inadvertent outgoing / incoming calls in places where incoming / outgoing calls are refrained and not causing radio interference to surroundings.

FIG. 7 is a block diagram showing the configuration of the fourth embodiment of the mobile communication terminal of the present invention. In this example, a card interface 35 is connected to the sub CPU 16, and the other configuration is the same as that of the third embodiment shown in FIG. When entering a hospital or the like, the user inserts a power stop lock card into the card interface 35. When the sub CPU 16 detects that the power stop lock card 300 has been inserted via the card interface 35, the sub CPU 16 turns off the switch circuit 64 and sends the power key switch 2 from the control terminal 231 of the power supply switch 23.
5 and the control terminal 231 is opened to stop the power supply to the wireless transmitting / receiving unit 50.

That is, in such a case, by inserting the pager setting card into the card interface 35, the sub CPU 16 can be set to the pager mode in the same manner as described above, and by pulling out the pager setting card, the sub CPU 16 can be set. The original mobile communication terminal mode can be set.

Next, when the above-mentioned received data detection signal is detected again by the data discriminating section 43 and the received data detection signal is inputted again to the power supply control section 131, the high level is applied to the base of the transistor T2 via the diode D8. Is applied for a predetermined period. Thereby, the transistor T2
Is turned on, a gate current flows through the gate of the FET, the FET is turned on, and the power of the DC power supply 26 is supplied from the regulator 21 to the wireless transmission / reception unit 50. This allows
The sub CPU 16 operates to return the main unit to the mobile phone mode, set the base of the transistor T3 to low level, and turn off the transistor T3, thereby restoring the function of the power key switch 25. Also, sub CP
U16 is a diode D when the power key switch 25 is pressed once to turn on the transistor T2.
9, the base of the transistor T2 is maintained at a high level, and the ON state of the FET is maintained. As a result, the function of the mobile phone is restored, and it is possible to make and receive calls at any time.
