14) Thereafter, the control unit 31 controls the base station 20 and other base stations so that the mobile phone can be permitted to make and receive calls (step 115).

For reference, FIG. 5 shows a configuration example of the storage unit 32 of the database 30. As shown in FIG.
Stores a subscriber number, a manufacturing number, a control signal, and a determination signal in a table format in which they are associated with each other, and the control signal and the determination signal can be rewritten at any time. The base station 20 controls the outgoing / incoming permission / non-permission of the corresponding subscriber number by reading the production number, the control signal, and the determination signal associated with the subscriber number for which the connection is requested from the storage unit 32.

Next, a simple concrete example will be described with respect to the unique number in the judging section 33, the confirmation of the presence or absence of the control signal, and the judging method. For example, the calling terminal 10 (mobile phone owner) has 0910345678 (subscriber number), 000 [1] (unique number. The number in [] indicates the FLAG bit indicating whether a unique number is added), 0 [1 ] (Control signal. The number in [] is a FLAG bit indicating whether or not a control signal is added).

The transmitted information is sent to the database 30 via the base station 20 and analyzed by the judging section 33. First, the determination of the unique number will be described. The determination unit 33 checks whether the unique number is transmitted from the FLAG bit at the end of the transmitted unique number, and when the unique number is not transmitted,
It is determined that the unique number has not been transmitted because there is no FLAG bit. If the FLAG bit is present, it is determined that the unique number has been attached and transmitted. Then, it is determined from the storage unit 32 whether the transmitted unique number is the same as the stored unique number corresponding to the subscriber number and whether the unique number is valid.

Next, the determination of the control signal will be described. The determination unit 33 checks whether the control signal is transmitted from the FLAG bit at the end of the transmitted control signal, and when the control signal is not transmitted, determines that the control signal is not transmitted because there is no FLAG bit. , If the FLAG bit is present, it is determined that the control signal is attached and transmitted. Then, it is determined whether the transmitted control signal is 0 or 1 and the determination signal is 0 or 1.

Next, the operation in the case where the calling terminal (mobile phone owner) 10 sets the incoming / outgoing call of the own mobile phone to be impossible will be described in more detail with reference to the flowchart of FIG.

Information of the mobile phone owner TX0
After transmitting (subscriber number B + serial number C + control signal 0) (step S1), the base station 20 receives the information TX0 and transmits the information TX0 to the database 30 (step S2).

The database 30 is the subscriber number B of the information TX0.
(Step S3), and the determination unit 33 confirms whether the serial number is added to the received information TX0 (step S3).
Four). When the serial number is not added, the base station 20 checks the setting of the mobile phone corresponding to the subscriber number B from the storage unit 32 of the database 30 to check whether the call is permitted or not. The control unit 20 controls to connect the wireless line of the corresponding mobile phone (step S11), and the base station 20 controls not to connect the wireless line of the corresponding mobile phone (step S12) when outgoing / incoming call is not permitted.

On the contrary, when it is determined in step S4 that the manufacturing number is added, the determination unit 33 of the database 30 is used.
Determines whether the serial number C is unique to the subscriber number B (step S5), and if the serial number C is not the corresponding serial number, the base station 20 disconnects the communication with the mobile phone owner (step S1).
3) If it is confirmed that the production number C is unique to the subscriber number B, then it is confirmed whether or not a control signal is added (step S6).

When the control signal is not added, the base station 20 disconnects the communication with the owner of the mobile phone (step S1).
3) If the control signal is added, the determination unit 33 of the database 30 determines the control signal and writes the control signal 0 / corresponding determination signal 0 to the storage unit 32 (step S7).

When the control signal is the control signal 0, the base station 20 controls the terminal of the corresponding subscriber number from the database 30 so that it cannot make or receive a call (step S8). If the control signal is not control signal 0, the base station 20 controls the terminal of the corresponding subscriber number from the database 30 so that the terminal having the corresponding subscriber number can be transmitted and received (step S9). Here, since the transmitting terminal 10 has transmitted the information TX0, the control signal is the control signal 0. Therefore, the control signal / judgment signal corresponding to the subscriber number B in the information TX0 is stored in the storage unit 32 of the database 30. Since the control signal 0 and the judgment signal 0 are written, the system side controls so as not to perform the incoming / outgoing call connection of the corresponding mobile phone until the control signal / judgment signal is changed.

Next, the operation in the case where the calling terminal (mobile phone owner) 10 sets to allow the incoming / outgoing of the owned mobile phone will be described in more detail with reference to the flowchart of FIG. In the figure, the same reference numerals are given to the same processing steps as in FIG. In this case, the transmitting terminal 10 transmits the information TX1 (subscriber number B + manufacturing number C + control signal 1) that enables the call originating / receiving (step S16 in FIG. 4). Then, the base station 20 receives the information TX1 and transmits the information TX1 to the database 30 (step S17 in FIG. 4).

After that, the same operation as in FIG. 3 is performed. That is, the database 30 searches the subscriber number B of the information TX1 (step S3 in FIG. 4), and the determination unit 33 confirms whether the manufacturing number is added (step S4 in FIG. 4). When the manufacturing number is not added, the base station 20 uses the database 3
The calling terminal 1 corresponding to the subscriber number B from the storage unit 32 of 0
For the setting of 0, it is checked whether the incoming / outgoing call is permitted or not, and if the outgoing / incoming call is permitted, the base station 20 determines that
0) Control the connection of the wireless line (step of FIG. 4)
S11), when the call origination / termination is not permitted, the base station 20 controls not to connect the wireless line of the corresponding mobile phone (calling terminal 10) (step S12 in FIG. 4).

On the contrary, when the manufacturing number is added, the determination unit 33 of the database 30 determines that the manufacturing number C is the subscriber number B.
It is judged whether it is unique (step S5 in Fig. 4) and the serial number
When C is not the corresponding serial number, the base station 20 disconnects the communication with the calling terminal (mobile phone owner) 10 (step S13 in FIG. 4), and the serial number C is unique to the subscriber number B. If it is confirmed, it is confirmed whether the control signal is added (step S6 in FIG. 4).

When the control signal is not added, the base station 20 disconnects the communication with the calling terminal (mobile phone owner) 10 (step S13 in FIG. 4), and when the control signal is added, the database 30 is sent. The determination unit 33 determines the control signal and writes the control signal 1 and the corresponding determination signal 1 to the storage unit 32 (step S18 in FIG. 4). here,
Since the control signal is the control signal 1, the base station 20 controls the mobile phone of the corresponding subscriber number B from the database 30 so that it can make and receive a call (step S9 in FIG. 4).

Thereafter, the control signal / judgment signal corresponding to the subscriber number B is written in the storage section 32 of the database 30 as control signal 1 and judgment signal 1, respectively, until the control signal / judgment signal is changed. The system side controls so that it is possible to connect and receive the relevant mobile phone.

As described above, according to the present embodiment, the information TX0 transmitted from the transmitting terminal 10 can be set to disable the incoming / outgoing call of the mobile phone indicated by the information TX0. Unauthorized use can be prevented. That is, in this embodiment, the mobile phone owner loses the mobile phone.
In order to make it impossible to make and receive calls to mobile phones because of being stolen, etc., the subscriber number of a lost or stolen mobile phone + unique number (manufacturing number) + control signal Information TX0 consisting of (enable) is transmitted from the transmitting terminal 10 to the wireless telephone connection network side, the database 30 authenticates the subscriber number / specific number for the transmitted signal, and the database 30 determines the control signal after confirmation. Since the corresponding judgment signal is determined and the control signal / judgment signal is written in the storage unit 32, the base station 20 thereafter controls so as to prohibit the incoming and outgoing calls of the corresponding mobile phone. is there.

Further, in this embodiment, since the owner himself / herself can set the calling / receiving of the corresponding mobile phone after the mobile phone is lost / stolen, the owner can make an unauthorized use when the mobile phone is lost. It is effective as a prevention method. For example, by registering a personal identification number on a mobile phone to be used in advance, it becomes possible to make a call only when the personal identification number is entered and the corresponding personal identification number is confirmed. In the traditional fraud prevention method to
Unauthorized use cannot be prevented if the mobile phone is lost and the corresponding mobile phone is handed over to a third party if the security code is entered in advance and the call is not set so that the call can be made. In the embodiment, even after the mobile phone is lost, it is possible to prevent the unauthorized use by transmitting the information TX0 indicating that the outgoing / incoming call is impossible from the calling terminal 10 as described above, which is an effective measure for preventing the unauthorized use.

Next, another embodiment of the present invention will be described. FIG. 6 is a block diagram of another embodiment of the wireless communication system according to the present invention, and FIG. 7 is a sequence diagram of the transmission / reception control method of FIG. 6, those parts that are the same as those corresponding parts in FIG. 1 are designated by the same reference numerals, and a description thereof will be omitted. Although the embodiment of FIG. 1 can prevent unauthorized use, it does not help the owner in finding the mobile phone. In this embodiment, a means for helping the discovery of a mobile phone is added to the previous embodiment.

In the present embodiment, as shown in FIG. 6, the mobile phone A responds to the trigger signal transmitted from the base station 20 when calling the mobile phone A, and outputs a voice that helps the mobile phone A to discover. The storage unit 42 that stores the voice, the voice circuit 43 that generates a voice, and the presence or absence of the trigger signal described above are determined, and if there is a trigger signal, a voice that helps the mobile phone discovery is automatically voiced from the storage unit 42. It has a control unit 41 which is operated to function as the circuit 43 emits.

First, the control operation for making the mobile phone owner's lost or stolen mobile phone A unable to make or receive calls will be described with reference to the sequence diagram of FIG. 7A. The mobile phone owner, like the previous embodiment,
First, from the transmitting terminal 10, information TX0 (subscriber number B + serial number
When C [unique number] + control signal 0) is transmitted to the base station 20 (step 201), the base station 20 transmits the information TX0 to the base station 20 shown in FIG.
After it is received by the internal wireless unit 21 shown in (1), it is sent from the internal control unit 22 to the database 30.

When the control unit 31 receives the information TX0 output from the base station 20, the database 30 searches for the subscriber number B in the information TX0 (step 202), and the determination unit 33.
It is checked whether or not the serial number C of the corresponding subscriber number B is added to the information TX0 received in (step 203). Judgment unit 3
In the case where the manufacturing number C is added in 3, it is confirmed that the manufacturing number C is the unique one attached to the corresponding subscriber number B by collating with the information read from the storage unit 32. The determination unit 33 receives the received information tx
The presence or absence of the control signal in 0 is confirmed, and when the control signal is added, the control signal 0 is judged.

The control signal is changed to the control signal 0 by the judging section 33.
When it is determined that the incoming / outgoing call of the corresponding mobile phone is disabled, the database 30 writes the control signal 0 and the corresponding determination signal 0 to the storage unit 32 (step 20).
4) Thereafter, the control unit 31 controls the base station 20 and other base stations so that the mobile phone A is not permitted to make or receive calls (step 205).

The above sequence is the same as in the previous embodiment, but in this embodiment, the database 30 is further added.
When the call control is performed on the mobile phone A by the control unit 31 to the base station 20 and other base stations,
The mobile phone A is controlled to attach and transmit a trigger signal for performing a control to assist the mobile phone discovery (step 206).

Then, the mobile phone A determines whether the above-mentioned trigger signal is attached at the time of calling its own station, and if there is the trigger signal, the control unit 41 of the mobile phone A stores in the storage unit 42.
The voice circuit 43 automatically outputs the voice for mobile phone discovery stored in advance from the voice circuit 43 (step 207). This helps to discover the mobile phone and prevents unauthorized use by a third party.

Next, the operation in the case of canceling the call origination / termination of the portable telephone to enable the call origination / termination will be described with reference to the sequence diagram of FIG. 7B. The owner of the mobile phone transmits the information TX1 (subscriber number B + manufacturing number C [specific number] + control signal 1) from the transmitting terminal 10 to the base station 20 (step 211). The base station 20 sends the information TX1 from the control unit 22 to the database 30. Database 30 has information TX1
After receiving, the subscriber number B is searched (step 212),
The determination unit 33 checks whether or not the serial number C of the corresponding subscriber number is added to the information TX1 received.

When it is confirmed by the judging section 33 that the serial number C is added (step 213), the serial number is added.
After confirming whether C is unique to the corresponding subscriber number B, the determination unit 33 confirms the presence or absence of the control signal in the received information TX1, and when the control signal is added, the control signal 1 Judge about. When the determination unit 33 determines that the determination signal is the determination signal 1 (allows the corresponding mobile phone to make and receive calls), the database 30 writes the control signal 1 and the corresponding determination signal 1 to the storage unit 32 (step 21
4) Thereafter, the control unit 31 controls the base station 20 and other base stations so that the mobile phone A can be called and received (step 215).

Then, the database 30 controls the mobile phone A to assist the mobile phone discovery when the control unit 31 controls the base station 20 and other base stations to call the mobile phone A. The control is performed so that the trigger signal for transmission is sent without being attached. In other words, control is performed so that the call is made to a normal mobile phone (step 21).

For reference, FIG. 10 shows a configuration example of the storage unit 32 of the database 30. As shown in FIG.
2 stores a subscriber number, a manufacturing number, a control signal, a judgment signal, and a necessity / unnecessity of transmission of a trigger signal in a table format in which correspondence of necessity / unnecessity of transmission of a control signal, a judgment signal, and a trigger signal is stored. It can be rewritten at any time. The base station 20 controls the outgoing / incoming permission / non-permission of the corresponding subscriber number by reading the production number, the control signal, and the determination signal associated with the subscriber number for which the connection is requested from the storage unit 32.

Next, the present embodiment will be further described with reference to a simple concrete example. Now, the mobile phone A is controlled so that it cannot be used. Similar to the previous embodiment, for example, the owner of the mobile phone has 09010345678 (subscriber number) and 000 [1] (unique number. The number in [] is a FLAG bit indicating whether or not a unique number is added). 0 [1] (control signal. The number in [] is a FLAG bit indicating whether or not a control signal is added) is transmitted. The transmitted information is sent to the database 30 via the base station 20 and analyzed by the determination unit 33.

First, the determination of the unique number will be described. The determination unit 33 checks whether or not the unique number is transmitted from the FLAG bit at the end of the transmitted unique number, and when the unique number is not transmitted, determines that the unique number is not transmitted because there is no FLAG bit, and the FLAG bit is not transmitted. If there is a bit, it is determined that the unique number is attached and transmitted. Then, it is determined from the storage unit 32 whether the transmitted unique number is the same as the stored unique number corresponding to the subscriber number and whether the unique number is valid.

Next, the determination of the control signal will be described. The determination unit 33 checks whether the control signal is transmitted from the FLAG bit at the end of the transmitted control signal, and when the control signal is not transmitted, determines that the control signal is not transmitted because there is no FLAG bit, If the FLAG bit is present, it is determined that the control signal is attached and transmitted.

At this time, since the control signal is 0, the determination signal is determined to be 0, and the database 30 performs control to help the mobile phone A find its own number and the mobile phone A when performing the call control of the mobile phone A. Trigger signal 1 [1] (the number in [] is a FLAG bit indicating whether or not the trigger signal is added) is transmitted. Then, when the mobile phone A receives its own station number + trigger signal, the control unit 41 stores voice data (eg.
"This mobile phone is owned by Ichiro Yamada. Excuse me *
Please contact us at ***. "etc. ) Is read from the storage unit 42 and the voice circuit 43
The audio signal is automatically converted into an audio signal and the speaker in the audio circuit 43 is caused to sound.

As a result, a third party cannot be used illegally, and can be used for finding a lost or stolen mobile phone. At this time, the storage unit 32 of the database 30 is once set to disable the use of the mobile phone A (that is, the determination of the mobile phone A of the storage unit 32 is made by the control signal 0 [1] sent by the mobile phone owner). By setting the signal to 0, that is, to disable the use of the mobile phone A), when the call control of the mobile phone A is performed unless this setting is canceled, the control that automatically assists the mobile phone discovery is always performed. Since a trigger signal for transmitting is sent to the mobile phone A, it is effective in preventing unauthorized use and finding the mobile phone.

Next, the operation in the case where the owner of the portable telephone sets the incoming / outgoing call of the possessed portable telephone to be impossible will be described in more detail with reference to the flowchart of FIG. After the mobile phone owner transmits the information TX0 (subscriber number B + manufacturing number C + control signal 0) using the transmitting terminal 10 (step S21), the base station 20 receives the information TX0 and sends the information TX0 to the database 30.
Is transmitted (step S22). Database 30 is information T
The subscriber number B of X0 is searched (step S23), and the determination unit 33
Check if the serial number is added in step (step S2
Four).

When the manufacturing number is not added, the base station 20 stores the subscriber number from the storage unit 32 of the database 30.
The setting of the mobile phone corresponding to B is checked whether the incoming / outgoing call is permitted or not (step S33), and when the outgoing / incoming call is permitted, the base station 20 controls to connect the wireless line of the corresponding mobile phone (step S34). When the outgoing / incoming call is not permitted, the base station 20 controls not to connect the wireless line of the corresponding mobile phone (step S35).

On the contrary, when the serial number is added,
The determination unit 33 of the database 30 determines whether the manufacturing number C is unique to the subscriber number B (step S25), and the manufacturing number C
If is not the corresponding manufacturing number, the base station 20 disconnects the communication with the mobile phone owner (step S36). Meanwhile, the serial number
When it is confirmed that C is unique to the subscriber number B, it is confirmed whether the control signal is added to the information TX0 (step S26).

When the control signal is not added, the base station 20 disconnects the communication with the owner of the mobile phone (step S3).
6), database 3 if a control signal is added
The 0 determination unit 33 determines the control signal and writes the control signal 0 and the corresponding determination signal 0 to the storage unit 32 (step S27). Here, since the control signal is the control signal 0, when the base station 20 calls from the database 30 to the terminal of the corresponding subscriber number, the base station 20 transmits the trigger signal by attaching it (step S28) and receives it. The control unit 41 of the mobile phone A determines whether or not the trigger signal is attached (step S30).

In this case, since the trigger signal is attached, the control unit 41 automatically reads the voice data from the storage unit 42 and automatically outputs the voice to the voice circuit 43 (step S31). After that, the storage unit 3 of the database 30
Since the control signal / judgment signal corresponding to the subscriber number B is written in 2 as control signal 0 and judgment signal 0, respectively,
Until the control signal / judgment signal is changed, the system side sends a trigger signal when calling the corresponding mobile phone, and the mobile phone A that receives the signal sends the trigger signal to carry out the above operation. A voice that helps to find the telephone is automatically transmitted, and it can be prevented from being illegally used, which is useful for finding the mobile telephone A.

Next, the same procedure in the case where the owner of the portable telephone sets the incoming / outgoing of the possessed portable telephone is described in more detail with reference to the flowchart of FIG. In the figure, the same reference numerals are given to the same processing steps as in FIG. Mobile phone owner has information TX1 (subscriber number B + serial number C + control signal 1)
After transmitting (step S41 in FIG. 9), the base station 20 transmits the information TX1.
Is received and the information TX1 is transmitted to the database 30 (step S42 in FIG. 9). The database 30 searches the subscriber number B of the information TX1 (step S23 in FIG. 9), and the determination unit 33 confirms whether the manufacturing number is added (step in FIG. 9).
S24).

When the manufacturing number is not added, the base station 20 stores the subscriber number in the storage unit 32 of the database 30.
The setting of the mobile phone corresponding to B is checked whether the incoming / outgoing call is permitted or not (step 33 in FIG. 9), and if the outgoing / incoming call is permitted, the base station 20 controls to connect the wireless line of the corresponding mobile phone ( In step S34) of FIG. 9, if the outgoing / incoming call is not permitted, the base station 20 controls not to connect the wireless line of the corresponding mobile phone (step S35 of FIG. 9).

On the other hand, when the manufacturing number is added,
The determination unit 33 of the database 30 determines whether the manufacturing number C is unique to the subscriber number B (step S25 in FIG. 9), and if the manufacturing number C is not the corresponding manufacturing number, the base station 20 determines that it is the owner of the mobile phone. The communication is disconnected (step S36 in FIG. 9), and when it is confirmed that the manufacturing number C is unique to the subscriber number B, it is confirmed whether or not the control signal is added (step S36 in FIG. 9).

When the control signal is not added, the base station 20 disconnects the communication with the owner of the mobile phone (step S36 in FIG. 9), and when the control signal is added, the judging section of the database 30 is disconnected. 33 determines the control signal,
The determined control signal 1 and the corresponding determination signal 1 are stored in the storage unit 3.
Write to 2 (step S37 in FIG. 9).

Since the control signal is control signal 1, the base station 20 performs a normal calling operation from the database 30 to the terminal of the corresponding subscriber number (transmits the signal without attaching the trigger signal) (step S29 in FIG. 9). ), The control unit 41 of the mobile phone A that has received it determines whether or not a trigger signal is attached (step S30 in FIG. 9). In this case, since the trigger signal is not attached, the control unit 41 controls to perform the normal operation (step S32 in FIG. 9).

Thereafter, since the control signal / determination signal corresponding to the subscriber number B is written in the storage section 32 of the database 30 as the control signal 1 and the determination signal 1, respectively, the control signal / determination signal is changed. Until then, the system side carries out the calling work of the corresponding mobile phone in the normal operation (the calling work is carried out without attaching the flag signal), and the mobile phone can be connected to the normal outgoing and incoming calls.

The present invention is not limited to the above embodiment, and can be applied to, for example, a mobile information wireless terminal other than a mobile phone.

[0067]

As described above, according to the present invention,
It has the following various effects. (1) The reliability of preventing unauthorized use of a mobile terminal by a third party can be improved. The mobile terminal owner number + unique number (manufacturing number) + control signal (corresponding mobile terminal in order to set the mobile terminal to be unable to make or receive calls due to loss or theft of the mobile terminal To the network side, the database authenticates the subscriber number / unique number for the transmitted signal, and after confirmation, the database judges the control signal and makes the transmission / reception prohibited. signal·
This is because by writing the determination signal in the storage unit in the database, the base station controls so as to disallow the incoming and outgoing calls of the corresponding mobile terminal.

(2) It is effective as a method for preventing unauthorized use when a mobile terminal is lost. The reason is that after the mobile terminal owner loses or steals the mobile terminal, the owner himself / herself can set the incoming / outgoing call of the corresponding mobile terminal. For example, by registering a personal identification number in a mobile terminal to be used in advance, it is possible to make a call only when the personal identification number is entered and it is confirmed that it is the corresponding personal identification number. Under the conventional method of preventing unauthorized use of mobile terminals, the mobile terminal corresponding to a third party is lost if the mobile terminal is lost and the setting is made so that the password can be confirmed and the call can be sent in advance. If the mobile terminal is passed over, illegal use cannot be prevented. However, in the present invention, even after the mobile terminal is lost, the mobile terminal cannot be called or called. Therefore, the subscriber number of the mobile terminal + unique number (manufacturing number) + This is because a control signal (which makes the corresponding mobile terminal unable to make and receive calls) is sent to the network side, and based on the signal sent, the base station can be controlled so as to prohibit the call from and to the corresponding mobile terminal. is there.

(3) There is a high probability that the owner can find the mobile terminal even after the mobile terminal is lost or stolen. The database controls the base station to send a trigger signal attached to a mobile terminal that has been lost or stolen when performing call control. This is because it is determined whether or not it is attached, and when the trigger signal is present, a prestored voice for finding the mobile terminal is automatically emitted.
This not only prevents the mobile terminal from being used illegally, but also increases the probability that the mobile terminal will return to the owner.
