JP2000151798A - Portable telephone provided with dial/data locking function - Google Patents

Abstract

PROBLEM TO BE SOLVED: To protect dialing or personal information without utilizing an exchange when a portable telephone is lost by locking the reading of those data when a caller's telephone number included in an incoming signal is matched with a previously stored locking telephone number. SOLUTION: The telephone number of a telephone set fixed in a home, e.g. is stored in lock processing No.411 stored in a 1st memory 41 as a locking telephone number. A caller's telephone number incoming through a base station is matched with the lock processing No.411, a control processing part 11 drives a timer 33 and starts calling tone processing to count time up to user's off hook. When the count value reaches previously determined off hook time, the processing part 11 executes the lock processing and ends the operation. When off hook is executed by a user, the processing part 11 displays a message for requesting the input of an identification(ID) number, and when an inputted ID number is matched with a previously stored ID number 413, unlocks the locked state. But when both the ID numbers is not matched with each other, the operation is ended.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone with a dial / data lock function, which recognizes a telephone number of a caller and, if the telephone number is a specific number, sets a dial lock or telephone of the telephone. The present invention relates to a telephone having a function of preventing leakage of personal data in the telephone.
It should be noted that the present invention is not limited to the generally referred to as “mobile phone”, and PHS is a matter of course, and communication means on a general public line such as a pager / mail phone / personal computer (information device) with a wireless communication modem. It can be used for all information terminals provided with.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. 6-1 discloses a conventional method for dial-locking a mobile phone by remote operation.
Japanese Patent No. 25305 (“mobile radio communication device”) can be exemplified. In the dial lock processing disclosed in this publication, the following procedure is performed. (1) If the on-hook state continues for a certain period of time after the call notification, the called mobile phone automatically forcibly performs off-hook processing and shifts to a signal receiving state. (2) A message for prompting a signal notification from the mobile phone to the other device (sender), for example, "This phone does not exist at the owner's current location. Please enter a message. " (3) Compare the PIN code signal (the most common dial tone) transmitted from the caller to the mobile phone after that and the PIN registered in the mobile phone, and if they match, dial lock status Move to

[0003]

However, the dial lock processing method disclosed in Japanese Patent Application Laid-Open No. 6-125305 described above has the following problems. (1) After the notification of the call, the state is temporarily set to the off-hook state. However, since this is not performed by selecting the caller, the same processing is performed for the call from the third party. The above-mentioned voice message that is meaningless to the user is sent, and this may cause unnecessary call charges to be charged.

(2) If the on-hook state continues for a certain period of time after the call notification, dial lock processing is performed.
The state of being unable to answer a call for a certain period of time is not necessarily the state of "lost phone". From the mobile phone to the other device (sender)
"This phone does not exist at the owner's hand now. Lock process will be performed, please enter your PIN code" to prompt signal notification (input and notification of PIN) to When listening to the nuance message, the third party may be willing to dial a mobile phone for some time, saying that it is better to confirm with the person. Also, this message can cause misunderstanding, and the misunderstanding caused by the message that "I cannot answer the phone for a certain period of time" as "Loss of phone" is a very troublesome problem for the person who wants to notify the urgent business. Can be As a countermeasure to this point, an appropriate value that does not easily cause misunderstanding can be set by selecting the “fixed time” setting until the dial lock is activated, but this method cannot completely solve this problem. It is possible.

(3) In order to perform dial lock, remote control of a mobile phone requires input of a password at the partner device, which is a burden on the user including the points described in (1) above. In addition to the problem described above, for example, assuming that the terminal is left behind in a train, it is difficult to communicate physically when entering a PIN (for example, the train enters a tunnel). It is necessary to develop products in consideration of operation and the like. Even in such processing, the error processing that occurs during a call is a very important problem from the viewpoint of reliability, and is one of the most important factors that makes product development difficult.

In recent telephones, PIM (Perso)
nal InformationManager) function or Manager
A phone book function is added even though it is not as sophisticated as the function. Then, as disclosed in Japanese Patent Application Laid-Open No. 6-125305 as a prior art, a lock mode,
Some telephones are provided with a "mode in which a password must be entered when the telephone is used when the power is turned on". When this mode is selected and executed, it can be considered that not only the dial lock but also other functions prepared in the telephone are locked and also play a role of preventing leakage of personal information. However, most users do not use this feature. The reason is that it is troublesome to simply enter a password every time the user uses it.

[0007] Looking at such conventional examples from the viewpoint that personal information is leaked to a third party when the telephone is lost, in the above-described example of the portable telephone, the dial lock or dialing when lost is lost. Since the suspension process is performed by stopping dialing from a lost mobile phone at the exchange, the dial lock does not take into account processing of personal information such as a telephone directory existing in the telephone. Therefore, leakage cannot be prevented. Also, in the example having the lock mode described later, since the mode is selected by the user, it cannot be said that it does not completely prevent the leakage of the personal information in the event of loss. .

[0008] The present invention has been made in view of the above-mentioned problems of the prior art, and performs dial lock in the event of loss by a more complete and more reliable method without the burden of a third party. It is another object of the present invention to provide a mobile phone which performs data lock to prevent leakage of personal information written in the mobile phone.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A mobile phone according to the present invention will now be described.
An embodiment will be described with reference to the accompanying drawings. FIG. 1 is a block diagram showing a main part of a configuration of an embodiment of a mobile phone according to the present invention. Also, FIG.
FIG. 1 shows an example of an apparatus in the case of embodying the present invention, and shows constituent elements of the apparatus in association with FIG. 1 and 2, reference numeral 1 denotes a mobile phone having a data / dial lock function, which is provided with a radio unit 21 and relays with a partner device 201.
The voice and communication control signal transmitted from the wireless communication unit 01 are processed by the control processing unit 11 that performs various controls in the mobile phone through the wireless unit 21.

The control processing unit 11 uses input controls, operation states, operation input states, operation and operation instructions, etc., performed by the user operating various buttons 51 to 53 such as a call button and a dial button. Display processing on display means to be performed by the user, ringing tone control for the speaker 31, control by the timer 33, read / write processing of the first memory 41 for control using a non-volatile memory, telephone directory used for managing personal information It performs various controls such as read / write processing of the second memory in which personal management information such as personal information is stored.
M), an I / O control / arithmetic processing unit (CPU). In FIG. 1 showing the present embodiment, the voice in the received signal is shown to be directly output from the wireless unit 21 to the speaker 31 in order to output the voice of the call content. In general, all processes for separating or combining signals / voice signals are once processed through the control processing unit 11. Here, in order to simplify the description of the main part of the present invention, "caller telephone number" And the like are shown in the normal processing path.

A lock control means as an element characterizing the present invention is provided in a part of the control processing unit 11 and mainly controls each device (button 51) based on various information contents stored in the first memory 41. ~ 53, speaker 31,
This is realized by I / O control for the wireless unit 21).
One of various information contents stored in the first memory 41
An example is shown in FIG. In FIG. 3, LockNo is a constant that can be registered by the user and has a meaning as a caller number for lock processing determination. The caller number received at the time of calling and the constant LockNo registered in this memory. Are compared with each other and lock control is performed. ScretNo is a constant that can be changed by the user and means a password for releasing the locked state. The input password and the SecretNo are compared to release the locked state.

Next, the operation of the portable telephone with a data / dial lock function shown in FIG. 1 will be described in more detail. A call notification is sent from the base station 101 to the radio unit 21 together with the caller telephone number, and the radio unit 21 receives the content,
Deliver to the control processing unit 11. FIGS. 4 and 5 show the contents of the control operation at the time of calling which is induced by the call notification in the control processing unit 11 and executed sequentially, according to the flow. The operation will be described.

First, variables for timer processing (TOut1, TOut
2) is initialized (step S1). In the present embodiment, the timer 33 transmits a time signal of a predetermined time to the control processing unit 11 based on the time management information stored in the first memory 41. Initialize variables. Variable TOut1
Is a variable TOut2
Is a variable used to determine whether or not to perform lock processing.
This variable is also one of the variables managed in the first memory 41 (see FIG. 3). In the initialization process, TOut1 = 0, TOut
2 = WAIT2 (WAIT2 is a constant indicating a wait time until normal processing, and is also managed by the first memory 41).

Subsequently, the caller number passed from the radio unit 21 is stored in the first memory 41 as CallNo (caller number saving variable) (step S2). Although omitted in the flow, when there is no caller (that is, in a non-notification state), this variable is set to a NULL (none) state. Then, the notified caller number CallNo is compared with the caller number LockNo for lock processing determination registered in advance by the user (step S3). If the comparison results match, it is determined whether the current state is the locked state (step S6:
The variable LockMode = 1 representing the current lock state of the lock means stored and managed in the first memory 41 is determined). If the lock state is established, the lock is released (Step S7: LockMode = 0), but the lock state is changed. If not, the timer (1) (timer for counting the time from the calling to the call) is started (step S8).

Although the details of the timer process will be described later, in the present embodiment, the timer 33 notifies the timer processing unit of the control processing unit 11 of the time information in a fixed time unit. In the processing operation executed and executed (see the flow of FIG. 8), each of the timer variables (TOut1, TOut
Since the flag processing is performed to determine whether or not the 2) is to be incremented, the management contents of the first memory 41 (FIG.
Although it is not specified, the flag for starting the timer exists in the first memory 41, setting the flag instructs the start of the timer operation, and resetting the flag indicates the start of the timer operation. The end will be instructed.

Returning to the flow of FIG. 4, if the comparison result of the caller numbers does not match (CallNo @ LockNo) in step S3, it is checked whether or not the current state is the locked state (step S4: the first memory 41 (The variable LockMode = 1 representing the current lock state of the lock means stored and managed is determined.) If the lock state, the process proceeds to step S9. If not, the caller number is indicated to the user. (Step S5).

FIG. 4 shows a flow under the condition that some data is stored as the constant LockNo. In this flow, the constant LockNo is NULL, that is, the user of the caller number for determining the lock process. If the registration has not been made and the variable CallNo is NULL, that is, if a call is received in the non-notification mode, the lock processing is performed. In order to eliminate such a situation, it is actually necessary to check whether the constant LockNo is NULL or not, so a step for that is prepared.
In the present embodiment, the determination of the locked state and the setting / release to the locked state are all performed by controlling the variable LockMode stored as one of the variables managed in the first memory 41. It is done by. That is, various control units not specified in the present embodiment, for example, a processing unit that refers to contents in a second memory provided as a memory in which personal management information such as a telephone directory is stored, This variable
It is possible to check the LockMode state, and to suppress the display if it is in the locked state.

After the above-described preprocessing, the ringing tone processing is started (step S9), and the time count variable TOut1 from the time of calling to the time of calling until the user performs off-hook processing is set to the lock start wait time WAIT1. It will wait until it reaches (steps S10 and S24).
It should be noted that a call may be canceled at the other party (calling side) during this waiting time, and it is necessary to control the notification indicating “call stop” from the base station 101 via the radio unit 21. Is omitted here. Further, the determination in step S24 is that the variable TOut1 controlled (increment processing at a constant timing) by the timer (1) started only when CallNo = LockNo and not in the locked state at this point in time sets the upper limit WAIT1 of the wait time. Is checked to see if it exceeds.

If the variable TOut1 exceeds WAIT1 in step S24, a lock process is performed (step S2).
5) After that, the termination processing of the timer (1) is performed (step S26), and various termination processing such as execution of the termination processing of the ring tone (step S27) is performed, and the control processing by the main call is terminated. If the start processing of the timer (1) (setting of the flag) is not performed, the timer (1)
Is not executed (details will be described with reference to the flow chart of FIG. 7), so that the determination does not proceed to the YES side.

On the other hand, if it is determined in step S10 that the off-hook process has been performed by the user, the flag is reset in the timer (1) and the ending process is performed (step S11). After performing various termination processes such as step S12), the notified caller number CallNo is compared again with the caller number LockNo for lock processing determination registered in advance by the user (step S13). If the comparison results match, the call is turned on to perform a timer check from the time of the call state (that is, at the start of a call by off-hook) to the time of disconnection processing (at the end of the call by the mobile phone owner on-hook). -Set the time variable TOut2 between the call OFF to 0 (step S1).
4) The timer (2) for lock control is operated (step S15). Thereafter, an off-hook process is performed (step S16), and a transition is made to a call state.

After shifting to the call state, the user performs on-hook processing (call button ON or disconnection button O again).
N) (Step S1)
7, S18), it is checked whether the timer (2) (variable TOut2) is a disconnection process for less than a certain time (WAIT2) (step S19), and if it is less than a certain time, a lock process (LockMode = 1) Is set) (step S2).
0). Here, the notified caller number CallNo and the caller number for lock processing determination registered in advance by the user
LockNo is compared with the LockNo (step S21). If the comparison results match, and the call is disconnected on the other side or the normal user is disconnected, the timer (2) is terminated (reset flag). Is performed (step S22), the state is set to the on-hook state (step S23), and the control process is terminated.

FIG. 6 shows a situation where a call is not being made or a call is being made.
When the "call button" is pressed, the content of the control operation induced and executed by the control processing unit 11 is shown in accordance with the flow, and the password is a password in a locked state and a dial input in an unlocked state. It is shown that. The operation will be described below according to the flow shown in FIG.

First, when the call button is pressed, it is checked whether or not the telephone is locked (step S61). As a result, if it is not in the locked state, an on-hook process is performed (step S62).
A general dialing process of notifying the base station 101 of the content input in step S1 through the radio unit 21 is performed (step S63), and the process ends.

On the other hand, when the locked state is established in step S61, a message as shown in FIG. 2 is displayed on the display device 34 (step S64), and thereafter, the input contents of the dial button 52 operated by the user are stored. (Step S65), the input content is compared with a pre-stored password (variable ScretNo) (Step S6).
6). Here, if the entered information matches the password,
The lock is released (step S67), and this processing is ended. If they do not match, processing for displaying a message prompting re-input, such as "Incorrect. Please re-enter." Is performed (step S68). If the disconnect button is pressed during this process (in many cases,
Since the call button is functioning as a call start / disconnect button, in this case, the call button is actually re-input), and the control operation ends with the lock state (step S69).

FIG. 7 shows the contents of the control operation performed not only for the display suppression / dialing suppression but also for the saving and deletion of the personal information in accordance with the flow. In the case of performing lock control including the save / delete processing of the personal information, step S in FIG.
20 and step S25 in FIG. 4 can be considered to be replaced by the flow illustrated in FIG. The operation will be described below according to the flow shown in FIG.

First, a lock process is executed (LockMode = 1 is set) in order to suppress a data display / dialing process as a process that can be performed thereafter (step S71). Next, off-hook processing is performed (step S7).
2) After this, the other party who performs the data transfer (actually,
An ID signal indicating that the data is to be transmitted is transmitted to the device that can transfer the extracted data (step S73). Waiting is made for an OK signal to allow reception of the data transmitted from the partner device (step S74). When the OK signal is received, a transmission code including packetization of the data contents in the second memory 42 is received. Then, it is transmitted (step S75). Upon completion of the transmission, the contents of the personal information such as the telephone directory in the second memory 42 are deleted (cleared) by initializing (step S7).
6) After performing on-hook processing (step S77),
This processing ends.

In order to realize the control contents of the flow of the lock control with automatic deletion shown in FIG. 7, the personal information receiving side is not a person (not a person, but a means capable of accepting and storing data, for example, at home). It is necessary to prepare a device such as a PC connected to a telephone line). It is inefficient to perform data transfer / memory erasure every time the lock process is performed. Therefore, when performing steps S20 and S25 in FIGS. Data transfer and memory erasure processing will always be performed at the time of the call from the caller's telephone number.In practice, however, it is limited to the case where it is locked for a certain number of times, or Considering a method such as starting a data transfer process or a memory erase process when a specific signal is transmitted through a device capable of receiving data on the partner device side in the technology, there may be a great advantage depending on use conditions. .

Finally, the flow of the timer processing section will be described. FIG. 8 shows that the control processing unit 1 is notified by the timer 33 every fixed time unit (for example, 10 ms).
1 shows the contents of the control operation induced and executed according to the flow. First, it is checked whether or not the timer (1) (timer for counting the time from calling to communication) is on (step S81). If the result is on, the corresponding timer variable TOut1 is incremented. (Step S82). Similarly, timer (2)
It is also checked whether or not (timer counting the time from call ON to call OFF) is ON (step S83), and if the result is ON, the corresponding timer variable TOut2 is incremented (step S83). Step S
84). Although the physical form for determining whether the timer (1) / timer (2) is in the ON state is not shown, the flag managed by the first memory 41 is the simplest embodiment. is there.
