Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication telephone using radio or the like that can move while communicating.
[0002]
[Prior art]
When the current telephone system in Japan sends an emergency call to 110 (Police) and 119 (Fire and Ambulance), the caller's phone number and other information are notified to the police and fire by the other party. Is done. Even if the emergency call ends, the police and fire department can call back if necessary. The same applies to a mobile communication telephone using radio or the like.
A mobile communication telephone using radio or the like includes a power switch. It is necessary to maintain the power-on state not only when making a call but also when waiting for an incoming call. Conversely, when it is not necessary to wait for outgoing calls or incoming calls, the power may be turned off.
[0003]
Based on FIG. 4, the mobile communication telephone in the conventional example will be described in more detail. The figure shows the blocks of the control system. The telephone control unit 1 is composed of a microprocessor and controls the entire mobile communication telephone 10. The memory 2 is a storage device for storing information processed by the microprocessor of the telephone control unit 1. The dial key 3 includes a number key, a call key, a disconnect key, and the like, and transmits information on the key pressed by the user to the telephone control unit 1. The wireless unit 4 controls the wireless unit. A power source 5 made of a battery supplies power necessary for the operation of the mobile communication telephone 10. The power switch 6 is a switch for the user to turn on / off the power supply 5 of the mobile communication telephone 10. As is apparent from this block diagram, the power supply 5 of the mobile communication telephone 10 is turned on / off by the power switch 6, and the user operates this.
[0004]
[Problems to be solved by the invention]
However, mobile communication telephones that use radio or the like can move while communicating, but if the power is turned off after making an emergency call to 110 or 119, the police or fire department will The problem of not being able to respond to the call back. On the other hand, there is a problem that if this is made good, the person who makes an emergency call for mischief may be encouraged.
[0005]
The present invention has been made in view of the above points. When an emergency call is made, the user cannot turn off the power, and the police, firefighters can be surely excluded except for the battery running out or moving out of service area. An object of the present invention is to provide a mobile communication telephone capable of receiving a call back from the side.
[0006]
[Means for Solving the Problems]
Emergency call telephone numbers such as 110 and 119 are registered in the mobile communication telephone. When a user dials a telephone number for emergency call such as 110, 119, etc., the telephone control unit of the mobile communication telephone detects that an emergency call has been made. By this detection, the telephone control unit of the mobile communication telephone keeps the power supply connected so that the power supply is not turned off regardless of the user's operation.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The mobile communication telephone according to the present invention is a mobile communication telephone using radio or the like that can move while communicating.
Storage means for storing the telephone number of the emergency call destination, determination means for determining that the call has been made to the emergency call destination, and power-on means for setting the power supply to always on after making the emergency call It is characterized by the provision.
[0008]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a control system of a mobile communication telephone according to an embodiment of the present invention. In addition, what attached | subjected the same code | symbol as FIG. 4 has each shown the same element, and abbreviate | omits description. The difference from the conventional example shown in FIG. 4 is that a power switch 7 is provided in parallel with the power switch 6.
[0009]
The memory means for storing the telephone number of the emergency call destination is the memory 2, the determination means for determining that the call is sent to the emergency call destination is the telephone control unit 1, and the power source 5 is always turned on after the emergency call is made. The power-on means to be set to on is a power switch 7 that is controlled based on a control signal from the telephone controller 1. That is, the power switch 7 is configured to be controllable by the telephone control unit 1. When the telephone control unit 1 turns on the power switch 7, the power supply 5 of the mobile communication telephone 10 continues to be on even if the user sets the power switch 6 to off. Further, the telephone number for emergency call is stored in the memory 2 and can be referred to from the telephone control unit 1.
[0010]
Next, the operation will be described. The telephone number transmitted by the user is transmitted from the dial key 3 to the telephone control unit 1. The telephone control unit 1 determines whether or not the dialed telephone number matches the emergency call telephone number registered in the memory 2. Even if the power switch 6 is operated, the power supply 5 of the mobile communication telephone 10 is set to be kept on.
[0011]
As a condition for canceling the state in which the power supply 5 cannot be turned off, a case where a call back is made from an emergency call destination, a case where a certain time has passed after the emergency call is finished, and the like can be considered. When the telephone control unit 1 determines that these conditions are satisfied and the power switch 7 is turned off, the user's operation becomes effective.
[0012]
FIG. 2 is a flowchart showing a control flow of the telephone controller of the mobile communication telephone in the embodiment of the present invention. In the figure, the numerical value following the symbol S indicates a step number.
[S1] The telephone control unit 1 detects that the user has transmitted the telephone number of the other party by pressing the dial key 3.
[S2] The telephone control unit 1 checks whether or not the telephone number of the other party whose user has pressed the dial key 3 matches the telephone number of the emergency call destination. If they match, the process proceeds to S3, and if they do not match, the process proceeds to the next step of S3.
[S3] The telephone controller 1 sends a control signal to set the power switch 7 to the on state.
[0013]
FIG. 3 is a block diagram of a control system of a mobile communication telephone according to another embodiment of the present invention. The difference from the conventional example shown in FIG. 4 is that a switch 9 is provided separately from the power switch 6. In this example, the power switch 8 can be controlled from the telephone control unit 1. The user's power on / off operation is performed by a separately provided switch 9. The telephone control unit 1 monitors the on / off state of the switch 9 based on the monitoring signal and controls the power switch 8 to turn on / off the power source 5. The telephone control unit 1 reflects the state of the switch 9 as it is in the state of the power switch 8 when no emergency call is made.
[0014]
When an emergency call is made, the telephone control unit 1 turns on the power switch 8 regardless of the state of the switch 9, and when a call back from the emergency call destination is made, it is constant after the emergency call ends. When the release condition such as when the time has passed is satisfied, the state of the switch 9 is reflected on the power switch 8 again to enable the user's operation.
[0015]
【The invention's effect】
As described above, the mobile communication telephone of the present invention is a mobile communication telephone that uses radio or the like that can move while communicating.
Storage means for storing the telephone number of the emergency call destination, determination means for determining that the call has been made to the emergency call destination, and power-on means for setting the power supply to always on after making the emergency call Because it was provided
If an emergency call is made, the user will not be able to turn off the power, be sure to receive a call back from the police or fire department, except for running out of battery or moving out of service area. Emergency calls can be prevented.
