TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mobile phone and an emergency call transmission method used for the same, and more particularly to transmission of an emergency call for making a call to the police or fire department in an emergency in the mobile phone.
[0002]
[Prior art]
Conventionally, in the case of a mobile phone, when a dedicated one-touch key is pressed to make a call to the police or fire department in an emergency, a call is automatically made to a pre-registered public lifesaving / emergency agency. It is known (for example, see Patent Document 1).
[0003]
However, in the above-mentioned method, after being connected to the line to the lifesaving / emergency agency, it is necessary to utter its own voice and communicate the emergency situation to the staff of the lifesaving / emergency agency. If the voice cannot be emitted, the emergency situation cannot be notified.
[0004]
Therefore, in a conventional mobile phone, an emergency call is sent to an emergency contact previously stored in a memory by pressing a key switch for emergency communication, and an emergency signal and a telephone number of the terminal itself are sent to the emergency. A method of notifying a contact as signal data has been proposed (for example, see Patent Document 2).

The mobile phone 1 is provided with two redundant key detecting means (# 1, # 2) 18 and 19 for one key 17, and the pressing order of specific keys for emergency calls, for example, "1", "1" When the order of "1", "0", and "call button" is detected by the emergency call judging means 20, the timer 21 is started upon the 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 of the CPU 13 or the like, the timer 21 times out. Then, the CPU 13 (or the CPU for communication control) 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 if the number of the emergency call is stored in the non-volatile memory 22, automatically dials based on the dial contents after the start. .
[0019]
As a result, the mobile phone 1 can reliably send an emergency call even when the CPU 13 is not operating due to a software failure, that is, even in an abnormal state (runaway, hang-up, etc.) due to a software failure. Become.

The emergency call detecting means 20 activates the timer 21 when the dial contents match the emergency call number registered in advance (see a7 in FIG. 2), and writes the dial contents 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 where the CPU 13 is in an abnormal state such as a runaway and cannot react. In this case, the key 17 is pressed by the CPU 13 and the contents of the dial are transmitted via the key detecting means (# 1) 18 (see b2, b4, b6 in FIG. 3). The contents are transmitted via key detecting means (# 2) 19 (see b1, b3, b5 in FIG. 3).
