Abstract

PURPOSE:To transmit a dial number even when a lock function is being operated when an inputted dial number is an emergency dial number in that area. CONSTITUTION:Table-arranged area code and emergency dial number of each country and the area code of its own station to be changed or updated by transmission from a base station are memorized in data memory 30. When the lock function is being operated and the dial number and a send key are inputted by a CPU circuit 34, the same area code as that of its own station is detected from a table memorized in the data memory 30 by a CPU 28. When coincidence between the inputted dial number and the emergency dial number in accordance with a detected area code is obtained, the dial number is transmitted in spite of the operation of the lock function.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone device,
In particular, for example, the present invention relates to a mobile phone device having a lock function for restricting outgoing calls by a personal identification number or the like.

[0002]

2. Description of the Related Art Conventionally, there is a mobile phone device having a so-called lock function that can be called only by inputting a personal identification number in order to prevent unauthorized use of the mobile phone device by persons other than the owner of the mobile phone device. When it is desired to send an emergency dial number such as 119 or 110 when the lock function is operated in such a mobile phone device, the holder of the mobile phone device may set the emergency dial number in advance. That is, in the conventional mobile phone device, when a call is made during the lock function operation, the entered dial number is compared with a preset emergency dial number, and if the two match, the call operation to the emergency dial number is performed. Is acceptable.

[0003]

However, in the conventional portable telephone device, the emergency dial number cannot be transmitted when the lock function is activated unless the holder sets the emergency dial number in advance. Further, since the emergency dial number differs depending on the country, there is also a problem that the emergency dial number for each country must be set in advance in order to be able to deal with each country.

Therefore, a main object of the present invention is to provide a portable telephone device capable of transmitting an emergency dial number when the lock function is activated, without the holder having to preset the emergency dial number.

[0005]

According to the present invention, in a portable telephone device having a lock function for limiting outgoing calls, a region code, an emergency dial number corresponding to the region code, and a region code of the own station are written, If it is judged that the dialed number matches the emergency dial number in the same area code as the own area code by referring to the memory, the call to the dialed number is permitted even when the lock function is operating. The mobile phone device is characterized in that

[0006]

When the dial number is input while the lock function is operating, the microcomputer searches the memory, for example, to determine whether there is the same area code as the area code of the own station. When there is the same area code, the emergency dial number corresponding to this code is searched in the memory. Then, when the searched emergency dial number includes the same number as the input dial number, transmission of the dialed number is permitted.

[0007]

According to the present invention, since the area code and the emergency dial number of each country are stored in memory, the emergency dial signal can be sent when the lock function is operating even if the holder does not set the emergency dial number. You can make a call. The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. 1, a mobile phone device 10 of this embodiment includes an antenna 12, a high frequency signal received by the antenna 12 is processed by a radio section 14, and a voice is filtered by a filter 16.
And is output from the speaker 20 via the amplifier 18. In addition, the sound input from the microphone 22 is transmitted to the amplifier 18
Then, the signal is input to the wireless unit 14 via the filter 16 and converted into a high frequency signal and transmitted from the antenna 12.

The filter 16 has an I / O interface 2
4, a CPU 28, a data memory 30 and a program memory 32 are further connected to the I / O interface 24 via a bus 26. In the data memory 30, the area codes and emergency dial numbers of each country arranged in a table as shown in FIG. 2 are stored in the first area, and the area code sent from the base station (not shown) is the second area.
It is stored in the area. The area code sent from the base station is stored in memory because the area where the mobile phone device 10 is used may change. For example, when the area code is used in the area “441” in Japan, the area code sent from the base station is stored. "4
The area code "41" is stored in the memory. After that, when the mobile phone device 10 moves to the area of the area code "440", the area code of "440" is sent from the base station in this area, so "441" is erased and "440" is stored in the memory. To do. A RAM having a backup power source, an EEROM, or the like can be applied as the data memory 30. A program for controlling the CPU 28 is stored in the program memory 32.

The I / O interface 24 also includes a key circuit 34 including a numeric keypad, a dial key, a clear key, a send key, an end key, a down key and an up key.
And the display 36 and the bell 38 are connected. The dial number or the like input by the key circuit 34 is displayed on the display unit 3.
6 is displayed and the bell 38 operates when a signal from the other party is received.

Referring to FIG. 3, the key circuit 3 is used for transmission.
The processing operation of the CPU 28 when 4 is operated will be described. First, when the dial number is input in step S1 and the send key is input in step S3, it is determined in step S5 whether the lock function is in operation. If the lock function is not in operation, transmission processing is performed in step S7. If the lock function is in operation, the data memory 3 is operated in step S9.
The area code of the own station is read from 0, and the table shown in FIG. 2 is searched in step S11. Then, in step S13, it is determined whether or not the same area code exists. If "NO", the process returns to step S11, but "Y"
If "ES", it is determined in step S15 whether or not there is the same dial number. If there is no same dial number, the process returns to step S1, but if there is the same dial number, a calling process is performed in step S7.

In this way, when the dial number and the send key are input from the key circuit 34 while the lock function is released, the number is passed through the filter 16 and the radio section 14 regardless of the contents of the dial number. Although the call is sent from the antenna 12, if the dial number and the send key are entered while the lock function is operating, the call processing will be performed only if the entered dial number is the emergency dial number of the local code of the own station. Be seen.
