DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone, and more particularly, to a mobile phone that prevents information leakage due to reception when the owner is absent.

[0002]

2. Description of the Related Art In a conventional portable telephone, if a response start button is pressed at the time of an incoming call, a telephone call can be made by anyone other than the owner. Therefore, if an incoming call is received when the owner is absent, the privacy of the owner cannot be protected. For this reason,
In some mobile phones up to now, the owner himself / herself can switch between enabling / disabling calls by pressing a password release number for unlocking the operation or inserting / removing a password release key. Things range from being proposed.

For example, Japanese Patent Application Laid-Open No. Hei 4-302245 discloses a technique that enables the operation of a mobile phone by determining the presence or absence of an ID card. This is because information necessary for the operation of the wireless telephone device as a mobile phone is stored in an ID card detachable from the wireless telephone device,
Only when this ID card is attached to the wireless telephone device and connected to the wireless telephone control circuit, the wireless telephone device can be operated and an incoming call can be made by the owner himself.

[0004]

However, in such a conventional portable telephone, if the ID card is removed from the portable telephone as a wireless telephone device, all incoming calls are stopped. Therefore, there is an urgent matter, and even when a call is made, it will not be possible to contact at all, and as a result, the inherent portability and convenience of the mobile phone will be impaired was there.

[0005] In addition, although the ID card and the password release key used in the portable telephone are originally functions for restricting outgoing / incoming calls by persons other than the owner, the operation of the portable telephone is stopped. As a result, it is impossible to read out information such as telephone numbers and names stored in the mobile phone, so that even a third party cannot completely view information that does not cause any problem. there were.

Further, since the above-mentioned IC card can be easily taken out of the portable telephone, there is a high possibility that the IC card is lost or stolen. If it is a telephone, this IC
There has been a problem that the use of the card not only allows the user to see the mobile phone information (ID, fee, etc.) but also causes abuse.

[0007] The present invention is to solve the above-mentioned conventional problems. By prohibiting a call other than the owner at the time of an incoming call, it is possible to prevent information leakage and prevent the original normal call from being interrupted. It is an object of the present invention to obtain a mobile phone that can be realized at a high speed.

[0008]

In order to achieve the above object, a portable telephone according to the present invention has an incoming call procedure registering section for registering an incoming call procedure inputted by a key from a key operation section, and a call is received. When there is no registration of the incoming call procedure,
The control unit is caused to immediately enter the call mode. On the other hand, when the incoming call procedure is registered, the call mode is set on condition that the incoming call procedure matches the incoming call procedure keyed in from the key operation unit. It is intended to be.

[0009]

In the portable telephone according to the first aspect of the present invention, the control unit causes the control unit to shift to a response holding mode when the registered incoming call procedure and the keyed-in incoming call procedure do not match. When a certain period of time has elapsed, the wireless unit is notified of the absence message.

In the portable telephone according to the second aspect of the present invention, when the registered incoming call procedure does not match the incoming key-in procedure, the control unit causes the control unit to shift to a response hold mode. Until a certain time has elapsed, when it is confirmed that the incoming call procedure matches based on the same key input as described above, the communication mode is set.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a portable telephone according to the present invention. In FIG. 1, reference numeral 11 denotes a key operation unit for registering an incoming call procedure at the time of incoming call, answering incoming calls, selecting various functions, determining, and the like; Provided within
Incoming call procedure registration unit for storing incoming call operation procedures, 1
Reference numeral 3 denotes an incoming procedure storage determining unit provided in the storage device 14 for determining whether an incoming procedure is stored.
A set time storage unit 8 is provided in the storage device 14 and sets and stores the response hold mode time T. Also, 15
Is a timer circuit for measuring the elapsed time t when shifting to the response hold mode, 16 is a control unit for performing various controls and data operations of the mobile phone, and 17 is a wireless unit for transmitting and receiving various data.

Next, the operation will be described in detail with reference to the flowchart of FIG. First, when in a call waiting state (step S21), the mobile phone is switched to the incoming call procedure registration mode by a key operation on the key operation unit 11 (step S22). By switching to the incoming call procedure registration mode, the control section 16 determines whether or not the incoming call procedure has been input by keying from the key operation section 11 and whether or not the incoming call procedure has been registered. The information is stored in the discriminating unit 13 (step S23), the incoming call procedure flag and the incoming call procedure storage discrimination flag are set, and the apparatus enters the incoming call waiting state (step S24).

When a call is made in such an incoming call waiting state, when the user of the portable telephone presses a key of the key operation unit 11 (step S25), the control unit 1 is activated.
6 first checks the state of the incoming call procedure storage discriminating section 13 (step S26), and if the incoming call procedure discriminating flag is set, matches the incoming call procedure with reference to the registered contents of the incoming call procedure registering section 12 (step S26). Step S27). If the incoming procedure discriminating flag is set at the time of checking the state of the incoming procedure storing and discriminating section 13, the mode is shifted to the talking mode, and the talking state is set (step S28).

On the other hand, in the matching of the incoming call procedure in step S27, the control unit 16 compares the contents stored in the incoming call procedure registration unit 12 in the storage device 14 with the incoming call procedure by the key operation input from the key operation unit 11. However, if the result of the comparison indicates that there is a match, the mode is switched to the call mode and the call state is established (step S28). On the other hand, if the respective incoming procedures do not match in step S27, the mode shifts to the answer hold mode (step S29).

With the transition to the response hold mode, the elapsed time t is measured by the timer circuit 15 after the transition, and the elapsed time t reaches the set time T set in the set time storage unit 18 in the storage device. The measurement of the time t is continued (step S30). At this time, the control unit 16 observes the key operation on the key operation unit 11, and when the key operation is performed (step S31), the incoming call procedure is again matched (step S32), that is, the incoming call procedure by the key operation is stored. If there is consistency with the incoming call procedure stored in the incoming call procedure registration unit 12 in the device 14, the mode shifts to the call mode,
A call state is set (step S28).

However, if there is no match, the measurement of the elapsed time t is continued again, and when the set time T is reached, a notification of the absence message is transmitted from the radio unit (step S3).
3), the mobile phone returns to the state of waiting for an incoming call (step S21), and thereafter executes the processing of step S22 and subsequent steps again.

In the embodiment, the set time T can be arbitrarily changed by a key input on the key operation unit 11. For this reason, the storage device 14
The set time storage unit 18 in the same manner as the reception procedure registration unit 12 and the reception procedure storage measurement unit 13 can be configured by a readable / writable RAM, a rewritable EEPROM, or a flash memory.

Further, in order to determine whether or not the incoming procedure has been registered, the incoming procedure registering section 12 has a writing pattern of the incoming procedure without providing the incoming procedure storage determining section 13 as described above. By determining whether or not the incoming call procedure is stored, it can be determined that the incoming call procedure is stored or not stored (for example, if all the bits are all 1, it is determined that the incoming procedure is not stored). 14 can be simplified and the cost can be reduced. The key operation in the response hold mode may not be always observed, but only the elapsed time t may be measured, and another process may be performed by interruption from the key operation unit 11.

[0020]

As described above, according to the present invention, there is provided an incoming call procedure registering section for registering an incoming call procedure keyed in from the key operation section, and when there is an incoming call, the incoming call procedure is not registered. In such a case, the control unit is caused to immediately enter the call mode. On the other hand, if the incoming call procedure is registered, the incoming call procedure must match the incoming call procedure keyed in from the key operation unit. Is set to be in the call mode, so that it is possible to make a call only when the incoming call procedure matches the registered incoming call procedure, thus preventing leakage of information due to a call other than the owner and privacy. The effect that can contribute to protection of this is obtained.

[0021]

According to the first aspect of the present invention, when the registered incoming procedure and the key-input incoming procedure do not match, the control unit causes the control unit to shift to a response hold mode, and for a predetermined time after the shift, When the time has elapsed, the wireless unit is notified of the absence message. In the response hold mode, the third party performs a receiving operation, so that the receiving procedure does not match, or the owner himself or herself operates the key. If the operation is put on hold by mistake, the call state will not be immediately cut off, and after a certain period of time,
By outputting the absence message, it is possible to prevent the calling side from continuing to wait for an incoming call and avoiding the caller from repeatedly calling back.

Further, according to the second aspect of the invention, the control unit, the to shift the response hold mode when the registered call procedure and the key input incoming steps do not match, a predetermined time after the transition Until elapse, when it is confirmed that the incoming procedure based on the same key input as described above matches, the call mode is set, so even if the owner himself makes a wrong key operation, correct key operation can be performed. By doing so, it is possible to obtain the effect that the call state can be reliably started and the call can be started without the call state being immediately cut off.
