Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile phone and an emergency call transmission method used therefor, and more particularly, to an emergency call transmission for making a call to a police or a fire department in an emergency in a mobile phone.
[0002]
[Prior art]
Conventionally, some mobile phones automatically call a pre-registered public lifesaving / emergency organization when a special one-touch key is pressed to make a call to the police or fire department in an emergency. It is known (see, for example, Patent Document 1).
[0003]
However, in the above method, after being connected to the line between the lifesaving and emergency facilities, the voice must be uttered and the emergency situation must be transmitted to the lifesaving and emergency personnel. When the voice cannot be emitted, the emergency situation cannot be notified.
[0004]
Therefore, in a conventional mobile phone, by pressing a key switch for emergency communication, an emergency call is sent to an emergency contact stored in advance in memory, and an emergency signal and the telephone number of the terminal itself are emergency A method of notifying a contact as signal data has been proposed (for example, see Patent Document 2).

[Problems to be solved by the invention]
In recent years, the number of multifunctional models equipped with various functions such as e-mail, browsing, phonebook, scheduler, etc. in addition to the telephone function has been increasing in mobile phones, and one of those functions, for example, the e-mail creation function is in operation. The telephone function cannot be used.
[0007]
Since this mobile phone has been improved in functionality by incorporating a large number of functions as described above, it is becoming increasingly difficult to make it without problems when realizing it. That is, if the terminal itself falls into an abnormal state (runaway, hang-up, etc.) due to a software bug or the like, naturally an emergency call cannot be made. In Patent Documents 1 and 2 above, various methods have been proposed for making calls to the police and fire departments in an emergency, but even if this method is used, any key input occurs in this abnormal state. An emergency call cannot be made if it is not accepted.
[0008]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-described problems and provide a mobile phone capable of making an emergency call even in an abnormal state where no key input is accepted and an emergency call sending method used therefor. .

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a mobile phone according to an embodiment of the present invention. In FIG. 1, a mobile phone 1 includes an antenna 11, a radio unit 12, a CPU (central processing unit) 13, a memory 14, a display unit 15, and a voice control unit that handles voice signals such as a speaker and a microphone (not shown). 16, a key 17, key detection means (# 1, # 2) 18 and 19, an emergency call determination means 20, a timer 21, and a nonvolatile memory 22.
[0015]
In this embodiment, when the CPU is installed in the mobile phone 1 for communication control and application execution, the key detection means (# 2) 19, the timer 21, the emergency call determination means 20, and the nonvolatile memory 22 are The CPU for communication control included in the wireless unit 12 takes charge.
[0016]
The cellular phone 1 is provided with two redundant key detection means (# 1, # 2) 18, 19 for one key 17, and a specific key pressing order for an emergency call, for example, “1”, “ When the order of “1”, “0”, “call button” is detected by the emergency call determination means 20, the timer 21 is activated at the time of detection, and the dial contents of the call button are stored in the nonvolatile memory 22. .
[0017]
In the mobile phone 1, the timer 21 is normally stopped by the CPU 13 within a specific time and the dial contents of the nonvolatile memory 22 are cleared. However, if the timer 21 is not stopped due to an abnormal state or the like, the timer 21 times out. Then, the CPU 13 (or the communication control CPU) is reset.
[0018]
The CPU 13 (or the CPU for communication control) refers to the non-volatile memory 22 at the time of restart by reset, and when the emergency call number is stored in the non-volatile memory 22, it automatically dials based on the dial contents after the start-up. .
[0019]
As a result, even when the CPU 13 is not operating due to a software failure in the mobile phone 1, that is, even when the mobile phone 1 is in an abnormal state (runaway, hang-up, etc.) due to a software failure, an emergency call can be reliably transmitted. Become.
[0020]
2 and 3 are sequence charts showing the operation of the mobile phone 1 according to one embodiment of the present invention, and FIG. 4 is a flowchart showing the operation at the time of restart by resetting the mobile phone 1 according to one embodiment of the present invention. is there. The operation of the mobile phone 1 according to one embodiment of the present invention will be described with reference to FIGS. In the following description, a case will be described in which an emergency call is made to No. 110. 4 is realized by the CPU 13 executing a program in the memory 14 (a program that can be executed by a computer).
[0021]
When the key 17 is pressed to the CPU 13, the dial content is transmitted through the key detecting means (# 1) 18 (see a2, a4, a6 in FIG. 2), and the dial content is also transmitted to the emergency call detecting means 20. Is transmitted through the key detection means (# 2) 19 (see a1, a3, a5 in FIG. 2).
[0022]
The emergency call detecting means 20 activates the timer 21 when the dial content matches the emergency call number registered in advance (see a7 in FIG. 2), and writes the dial content in the nonvolatile memory 22 (a8 in FIG. 2). reference).
[0023]
When the CPU 13 is operating normally, a stop instruction is sent to the timer 21 (see a9 in FIG. 2), and a clear instruction is sent to the nonvolatile memory 22 (see a10 in FIG. 2), so nothing is executed.
[0024]
FIG. 3 shows a state in which the CPU 13 is in an abnormal state such as runaway and cannot react. In this case, the key 13 is pressed to the CPU 13, and the dial content is transmitted via the key detecting means (# 1) 18 (see b2, b4, b6 in FIG. 3), and the dial is also sent to the emergency call detecting means 20. The contents are transmitted through the key detection means (# 2) 19 (see b1, b3, b5 in FIG. 3).
[0025]
The emergency call detection means 20 activates the timer 21 when the dial content matches the emergency call number registered in advance (see b7 in FIG. 3), and writes the dial content in the nonvolatile memory 22 (b8 in FIG. 3). reference).
[0026]
However, in this case, since the CPU 13 is in an abnormal state such as runaway, the timer 21 does not stop, so that the timer 21 resets the CPU 13 when a predetermined time has elapsed (timeout) (b9 in FIG. 3). reference).
[0027]
The CPU 13 that has been reset performs the operation shown in FIG. 4 after restart by reset. That is, after restarting by reset, the CPU 13 checks the nonvolatile memory 22 (step S1 in FIG. 4), and checks whether the dial number is stored in the nonvolatile memory 22 (step S2 in FIG. 4).
[0028]
If the dial number is stored in the nonvolatile memory 22, the CPU 13 makes an emergency call using the dial number stored in the nonvolatile memory 22 (step S4 in FIG. 4). On the other hand, as shown in FIG. 2, if the CPU 13 is operating normally, the dial number is not stored in the non-volatile memory 22, so that nothing is done and normal operation is performed (step S3 in FIG. 4). ).
[0029]
As described above, in this embodiment, an emergency call can be transmitted even if an abnormal state occurs in which the mobile phone 1 does not accept any key input by inputting an emergency call destination in advance. Can do.
[0030]
FIG. 5 is a diagram showing a configuration example of the memory 14 according to another embodiment of the present invention. The other embodiment of the present invention has the same configuration and operation as the embodiment of the present invention shown in FIG. 1 except that the emergency call transmission sequence is stored in the memory 14.
[0031]
In FIG. 5, in the case of the police, the order of “disconnect 5 times or more”, “1”, “1”, “0”, “call button” is stored in the memory 14 as an emergency call transmission sequence. In this case, the order of “cutting 5 times or more”, “1”, “1”, “9”, “call button” is stored.
[0032]
In the order of “1”, “1”, “0”, and “send button” as described above for sending an emergency call, there is a possibility that the same key as that order may be pressed during character input. Therefore, in another embodiment of the present invention, as shown in FIG. 5, it can be replaced so that it can be activated when a specific settable key sequence is inputted.
[0033]
【The invention's effect】
As described above, according to the present invention, in a mobile phone, a timer is started when a predetermined key pressing order is detected, and the contents of the pressing order are written to the memory. By reading and dialing the contents, an emergency call can be made even in an abnormal state where no key input is accepted.
