The present invention relates to a wireless telephone, and in particular, when a certain time has elapsed after detaching the portable device from the fixed device, or when any button switch is pressed while the portable device is detached from the fixed device, The present invention relates to a wireless telephone having an emergency telephone number dialing function for automatic dialing.

Conventional cordless telephones are more difficult to use because they are more complicated to operate than ordinary telephones. There was this.

The present invention has been made to solve the above-mentioned problems. When the mobile device is detached from the fixed device or the mobile device is stored in advance with a telephone number capable of emergency contact, the present invention is applied to the keypad. It is an object of the present invention to provide a wireless telephone having an emergency telephone number dialing function that automatically dials a telephone number memorized in advance when an arbitrary button switch is pressed.

In order to achieve the above object, the present invention provides a transmitter (3) for transmitting various signals to a fixing device, a receiver (4) for receiving various signals from the fixing device, and an operation of the transmitter (3). In a cordless telephone having a portable device including a central processing unit (2) for controlling, etc., the central processing unit (2) of the portable device is a case where the portable device is separated from the fixed device in a charged state and the portable device Checking whether an emergency dialing mode is set when any button switch is pressed in a state where the button is separated from the fixing device, and when the emergency dialing mode is not set, normal operation is performed and the emergency dialing is performed. If the mode is set, dialing an emergency telephone number stored in an off hook state beforehand; The present invention provides a wireless telephone having an emergency telephone number dialing function, the program comprising the step of dialing the emergency telephone number a predetermined number of times when a call is not made after dialing a call.

With this arrangement, the present invention memorizes the emergency phone number in advance and presses any button switch on the keypad when the portable device is detached from the fixed device or the portable device is detached from the fixed device. In this case, the memorized phone number is automatically dialed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a portable device of a wireless telephone according to the present invention, and FIG. 2 is a flowchart of an emergency telephone number dialing operation performed in the mobile device of FIG. As can be seen in FIG. 1, the portable device 1 of the radiotelephone includes a central processing unit 2, a transmitter 3, a receiver 4, a call progress decoder 5 and a keypad. (6), the emergency dialing mode setting switch (7), the speaker 8, the microphone 9 and the antenna 10 is configured to be connected. The central processing unit 2 controls the overall operation of the portable device 1, and the transmitting unit 3 modulates the voice signal and the dialing signal input from the microphone 9 and fixes the fixed device through the antenna 10 (Fig. (Not shown in the figure). The receiver 4 demodulates the call signal and the voice signal input through the antenna 10 from the fixing device and outputs the signal to the speaker 8, and some of the incoming signal and the busy signal to the speaker 8 side. A part is output to the call progress decoder 5 side. The call progress decoder 5 outputs information on the central processing unit 2 when the telephone line of the other party is busy or does not answer the call. The keypad 6 is provided with a button switch for dialing a telephone number to input a telephone number to the central processing unit 2, and the emergency dialing mode setting switch 7 switches the mode for dialing an emergency telephone number. It is for setting in (2). In order to perform emergency phone number dialing operation, first enter a phone number for urgent contact using the keypad 6 and store it in the central processing unit 2, and emergency dialing using the emergency dialing mode setting switch 7. The mode must be set in the central processing unit (2).

The portable device 1 performs the emergency telephone number dialing operation in the same order as in the flowchart of FIG. First, the central processing unit 2 checks whether the portable device 1 is being charged by receiving power from the fixed device (step 20), and if the portable device 1 is removed from the fixed device when charging, Step 21), confirms that the emergency dialing mode is set (step 23), performs normal operation if the emergency dialing mode is not set (step 24), and OFF HOOK if the emergency dialing mode is set. After making a state, dial the emergency telephone number memorized in advance (step 25). After dialing, check if the call was made (step 26), if the call was not made, put it in an on-hook state (step 27), and then check the number of times the emergency number was dialed (step 27). 28) If the number of dials is less than or equal to the predetermined number of times, go to Step 25 to perform the operation of the next step; if the number is dialed more than the predetermined number of times, the operation ends. In step 20, if the portable device 1 is being charged and it is not charging (if the mobile device is disconnected from the freezing device), pressing any button switch (step 22) Similarly, the operation after step 23 is performed. When the call is terminated after making a call by emergency phone number dialing operation, when the portable device 1 is attached to the fixed device and switched to the charging state, the central processing unit 2 makes the portable device 1 on hook. To end the call.
