BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication between a first communication device and a second communication device when the identification information sent from the first communication device to the second communication device is proper. The present invention relates to a call establishment system that establishes a call, and relates to a mobile communication system that prevents unauthorized use of the first communication device.

[0002]

2. Description of the Related Art Conventional Example 1. FIG. 7 is a block diagram showing the configuration of a conventional mobile communication system. In FIG. 7, reference numeral 1 is an operating unit for a user to operate the mobile device 7 of the mobile communication system, for example a keyboard, and 2 is a mobile device 7 of the mobile communication system.
A control unit for controlling the whole and a MCU for performing various control processes
2 is a memory, 5 is a high-frequency circuit section, and 6 is an antenna. Reference numeral 7 denotes a mobile device including the operation unit 1, the control unit 2, the high frequency circuit unit 5, and the antenna 6. Reference numeral 8 is a base station that communicates with the mobile device 7.

Next, the operation will be described. When the mobile device 7 of the mobile communication system is in a callable state and the user performs a call operation through the operation unit 1, the processing unit 3 in the control unit 2 is connected via the high frequency circuit and the antenna 6. The processing necessary for establishing a call path for making a call is performed with the system via the base station 8 and the call is started.

In order to prevent unauthorized use, the mobile device 7 of a general mobile communication system stores both subscription and individual authentication information for each mobile device 7 in a memory 4 inside the mobile device 7. The control side also stores the same authentication information. When making an outgoing call, the processing unit 3 of the mobile station reads these pieces of information from the memory 4 between the calling and the start of the call, and sends the information to the control side through the base station 8. The control side determines whether or not these pieces of information from the mobile device 7 are properly registered. That is, a method of preventing illegal use of the mobile device 7 on the system by authenticating the mobile device 7 has been adopted. However,
Since the authentication information stored in the memory 4 inside the mobile device 7 cannot be changed, if the same information as the stored information inside the mobile device 7 is once copied to another mobile device 7, it will be regarded as a legitimate mobile device 7. It becomes usable in the system in exactly the same way.
Therefore, such authentication of each mobile device 7 cannot necessarily exclude the unauthorized use of the mobile device 7.

Conventional example 2. In addition, conventionally, there has been a mobile communication system shown in FIG. In this conventional mobile communication system, the user of the mobile device 7 can freely determine the authentication code, and the authentication code is stored in the control side. The user of the mobile device 7 inputs this authentication code using the operation unit 1 at the time of starting the outgoing call every time (step S61) (step S62), and the mobile device 7 side through the base station 8 The authentication code input to the control side is transmitted (step S63).
Unless the authentication code sent from the mobile device 7 matches the authentication code stored in the control side, the call cannot be started.

Such an authentication code for authenticating the user of the mobile device 7 is generally a Personal Identificati
It is called on Number (abbreviation PIN). If this authentication method using a PIN is used together, for example, even if the above-mentioned individual authentication information for each subscription and mobile device 7 is copied to another mobile device 7, the owner user of the mobile device 7 changes the PIN individually. By doing so, it is possible to easily eliminate the illegal use of the mobile device 7.

[0007]

In the mobile communication system according to the conventional example 1, since the authentication information stored in the memory 4 inside the mobile unit 7 cannot be changed, the same information as the stored information inside the mobile unit 7 is different. Once copied to the mobile device 7, the mobile device 7 can be used in the system just like the regular mobile device 7. Therefore, such authentication for each mobile device 7 has a problem that the unauthorized use of the mobile device 7 cannot always be excluded. In addition, in the mobile communication system in the conventional example 2, the user of the mobile device 7 needs to input the PIN using the operation unit 1 every time when the outgoing call is started. Therefore, the operation procedure up to the start of the call is complicated and very troublesome for the user. Further, since the operation procedure is complicated, an incorrect PIN is also input, and in this case, the call cannot be started and the call fails.

The present invention has been made to solve the above problems, and an object thereof is to more effectively eliminate illegal use.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1. The communication system according to this embodiment will be described below. FIG. 1 is a flow chart showing the operation procedure of the communication system in this embodiment. The configuration of the communication system in this embodiment is similar to that of the block diagram shown in FIG. In this specification, the base station 8 shown in FIG.
The control stations (not shown) that control the above are collectively referred to as the control side. However, in the mobile device 7 in this embodiment, the user can freely determine the PIN by operating the operation unit 1, and the determined PIN is stored in the memory 4 in the mobile device 7. It has a function that can do.

Next, the operation will be described. In this embodiment, the processing unit 3 controls the mobile device 7 so that the PIN previously determined by the authorized user can be stored in the memory 4 in the mobile device 7. For example, when the user manually inputs the PIN from the operation unit 1 and executes the writing of the PIN, the PIN is written in the memory 4. In addition, you may make it use the input means other than this. However, the PIN input by the user is freely decided by the user himself, and this PIN is notified to the control side in advance. The control side stores the PIN determined by the user.

Next, the operation during an actual outgoing call will be described. It is assumed that the user has previously stored the PIN in the memory of the mobile device 7 by the above operation. Further, the subsequent processing is performed based on an instruction from the processing unit 3. The calling process is started when the user of the mobile device 7 performs a calling operation. For example, the calling process is started by the user pressing the off-hook button and inputting the telephone number of the other party. In FIG. 1, first, a process for starting the establishment of a communication path with the base station 8 is started (step S1).

When the establishment start process is started, the processing unit 3 in the mobile unit 7 judges the timing of sending the PIN, reads the PIN stored in the memory 4,
Control is performed so that the read PIN is automatically sent to the base station 8 via the high frequency circuit 5 (step S2).
After that, the control side including the base station 8 determines whether the PIN sent from the mobile device 7 and the PIN stored in advance by the control side match (step S3). Then, when the PIN sent from the mobile device 7 and the PIN stored on the control side match each other, the communication path to the mobile device 7 is secured (step S4). Once the call path is secured,
A call can be made by the user of the mobile device 7 (step S
5). On the other hand, if the PIN sent from the mobile device 7 and the PIN stored on the control side do not match, the base station 8 rejects the call start (step S6).

As described above, according to the above-described embodiment, the PIN freely decided by the user is stored in the memory 4, and the PIN is automatically transmitted when necessary.
Even in the mobile communication system that adopts the PIN authentication, it is effective in that the operation of the mobile device 7 is not complicated.

In addition, P stored in the memory 4 of the mobile unit 7
Since the IN can be changed by the user, if the mobile device 7 itself is stolen, or if it is determined that there is an unauthorized mobile device 7 that copies the above-mentioned various authentication codes, the mobile device 7 is moved. The user of the machine 7 can change the PIN stored in the memory 4 and can change the PIN on the control side to prevent the unauthorized use thereafter. The presence of an unauthorized mobile device 7 is recognized when the regular user is charged more than he actually used.

Although the PIN has been described as being freely decided by the user of the mobile device 7, if the restriction is imposed so that there are no two or more mobile devices 7 having the same PIN on the system, the PIN will be as follows. It is advantageous in that That is, the same P
When there are two or more mobile devices 7 having IN in the system, it can be recognized that any one of them is illegally used. Since this recognition can be performed by the control side, it is effective when the authorized user does not know the existence of the unauthorized user.

In this embodiment, the case of making a call from the mobile device 7 has been described, but the present invention can be applied to other cases. For example, if the PIN is transmitted when the mobile device 7 receives a call, it is possible to prevent the mobile device 7 of an unauthorized user from being called. Also, if the user forgets the PIN, the user can use the mobile device 7 by changing the PIN.

Further, in this embodiment, the case where the process for establishing the communication path is performed by software is described, but it is also possible to perform the same process by hardware. That is, it can be realized by providing means for executing the above steps. This point also applies to the following embodiments.

In this embodiment, the method and apparatus for establishing a call between the mobile station 7 and the base station 8 have been described, but the present invention can be applied to other communication modes. For example, it can be applied to a method of establishing a call between the mobile device 7 and the mobile device 7. The mobile device 7 and the base station 8 in this embodiment are examples of communication devices. In this respect, the same applies to the following embodiments.

Embodiment 2. In the above-described embodiment, the user preliminarily sets the PIN on the mobile device 7.
Was stored and the PIN was automatically sent out when necessary, but it was stolen by controlling the lock function of the mobile device 7 itself and the automatic PIN sending operation in cooperation with each other. In this case, illegal use can be prevented more efficiently.

Here, the lock function is for preventing any function of the telephone even if the telephone is powered on. Therefore, in the locked state, all the functions of the mobile device 7 are stopped, and the call cannot be made and the call cannot be made. This function is a function for preventing an accidental use such as a case where the device is stolen, or an accidental accident in which a phone call is unnecessarily paid due to a child's mischief. In order to release the locked state, it is necessary to input the unlocking password previously stored in the memory 4.

Next, the operation of this embodiment will be described.
The configuration of the communication system in this embodiment is the same as that shown in FIG. 7, and the description thereof will be omitted. Figure 2
7 is a flowchart showing this embodiment, and corresponding portions are denoted by the same reference numerals as those in FIG. When the user of the mobile device 7 initiates a call process by performing a call operation, the processing unit 3 of the mobile device 7 first starts the current call after the mobile device 7 is powered on. By then, it is determined whether the correct lock personal identification number has been input (step S1).
1). Specifically, whether the personal identification number input by the user from when the mobile device 7 is powered on until the current call is started and the personal identification number for locking stored in the memory 4 in advance match. Determine whether or not. Then, depending on the determination result, it is selected whether to execute steps S12 to S13 or steps S14 to S16.

If the entered personal identification number is correct, the mobile unit 7 starts the communication path start establishing process (step S1).
2) The PIN stored in advance in the mobile device 7 is automatically transmitted (step S13). If the entered personal identification number is incorrect, the mobile device 7 starts the communication path establishing process (step S14), and thereafter requests the operation unit 1 to input the PIN. This request is made by displaying it on the display of the mobile device 7. When the user inputs a PIN with the operation unit 1 in response to the input request (step S15), the mobile device 7 sends out the input PIN (step S16).

Next, the control side determines whether or not the PIN transmitted from the mobile unit 7 matches the PIN registered on the network side (step S17). Then, the PIN transmitted from the mobile device 7 is the PIN registered on the control side.
If it matches with, a process for starting a call is performed between the mobile device 7 and the base station 8 (step S18), and the call is started (step S19). On the other hand, when the PIN transmitted from the mobile device 7 does not match the PIN registered on the control side, the base station 8 rejects the call start (step S110).

The above processing is executed each time the calling processing is started regardless of whether the mobile device 7 is in the locked state or not. Also, if the correct PIN code for lock is entered between the time the power is turned on and the call processing is performed, it is not necessary to enter the PIN code after the call starts, so you can make a quick call. Is possible. Furthermore, if the correct lock PIN is not entered between the time the power is turned on and the call processing is performed, the PIN is operated from the operation unit 1, so the correct lock PIN is entered. Correct PIN even if you did not enter it
If you know it, you can make a call.

As described above, when the calling process is performed, the result of determination as to whether or not the correct lock personal identification number has been input from when the power of the mobile device 7 is turned on to when the calling process is started is obtained. Accordingly, it is determined whether the PIN is taken out from the memory 4 or the PIN is input from the operation unit 1, so that it is possible to effectively prevent illegal use by an unauthorized user. That is, it is determined whether or not the user is a legitimate user by monitoring the past input situation, and if the legitimate user is suspected, the PIN is directly input to confirm the legitimacy. Confirm whether you are a user or not and prevent illegal use more effectively.

Embodiment 3. In the above-described embodiment, the user has previously set the PIN on the mobile device 7.
Was stored, and the PIN was automatically sent out when necessary, but it was stolen by controlling the security function of the mobile device 7 itself and the automatic sending operation of the PIN number in cooperation with each other. It is possible to effectively prevent illegal use in the case of

Here, the security function is to prevent a specific function of the mobile device 7 from operating unless the user inputs the correct security personal identification number. By using this security function, for example, incoming calls can be made, but transmissions cannot be made, setting of various personal identification numbers cannot be changed, and private information stored in the mobile device 7 can be accessed. It is possible to prevent such access. By using this security function, it is possible to more effectively prevent unauthorized use by a third party.

As in the case of the lock, the personal identification number for the security function is written in the memory 4 of the mobile unit 7,
This can be realized by comparing the number input from the operation unit 1 and the personal identification number written in the memory 4 in the processing unit 3. The purpose is to prevent anyone other than the original user from accidentally or illegally using the specific function of the mobile device 7.

Next, the operation of this embodiment will be described.
The configuration of the communication system in this embodiment is the same as that shown in FIG. 7, and the description thereof will be omitted. Figure 3
It is a flow chart showing this embodiment, and corresponding portions are denoted by the same reference numerals and the description thereof is omitted. When the calling process is started by the user of the mobile device 7 performing a call operation, the processing unit 3 of the mobile device 7 first starts the call this time after the mobile device 7 is powered on. It is determined whether the correct security code has been input at least once before (step S21). Specifically, the personal identification number input by the user from when the mobile device 7 is turned on until the current call is started and the personal identification number for releasing the security stored in the memory 4 in advance match. Determine whether to do. Then, depending on the determination result, steps S22 to S23 are executed or steps S24 to S are performed.
26 is selected.

If the entered personal identification number is correct, the mobile unit 7 starts the communication path establishing process (step S22),
The PIN previously stored in the memory 4 of the mobile device 7 is automatically transmitted (step S23). If the entered personal identification number is incorrect, the mobile device 7 starts the communication path establishing process (step S24), and then the PIN is input from the operation unit 1.
Make a request to enter. This request is made by displaying it on the display of the mobile device 7. When the user inputs the PIN with the operation unit 1 in response to the input request (step S25), the mobile device 7 sends out the input PIN (step S26).

Next, the control side determines whether or not the PIN transmitted from the mobile device 7 matches the PIN registered on the network side (step S27). Then, when the PIN transmitted from the mobile device 7 matches the PIN registered on the network side, a process for starting a call between the mobile device 7 and the base station 8 is performed (step S2
8) The call is started (step S29). On the other hand, if the PIN transmitted from the mobile device 7 does not match the PIN registered on the network side, the base station 8 rejects the call start (step S210).

The above processing is executed every time the calling processing is started regardless of whether the mobile device 7 is in the security state or not. Also, if the correct security code is entered between the time the power is turned on and the call processing is performed, it is not necessary to enter the code after the call starts, so you can make a call quickly. Is possible.
Further, if the correct security code is not entered from the time the power is turned on until the call processing is performed, the PIN is operated from the operation unit 1, so the security code is entered. Even if you have not done so, you can make a call if you know the correct PIN.

As described above, when the calling process is performed, the result of determination as to whether or not the correct security password has been input from the time when the power of the mobile unit 7 is turned on to the time when the calling process is started. Depending on whether the PIN is taken out from the memory 4 or P
Since it is determined whether IN is to be input from the operation unit 1, it is possible to effectively prevent illegal use by an unauthorized user. Further, the time and effort required for the PIN input by the authorized user can be saved. That is, it is determined whether or not the user is a legitimate user by monitoring the past input status, and if the legitimate user is suspected, the PIN is directly input, so that the legitimate user can Check if there is.

Fourth Embodiment In the first embodiment, the P stored in the mobile device 7 in advance is stored.
Although the IN number was only sent automatically, the mobile unit 7
When the power is turned on, the user inputs the PIN, and only when the input result matches the PIN stored in the predetermined mobile unit 7, the subsequent automatic PIN sending operation may be performed, and the PIN is stolen. In this case, illegal use can be effectively prevented.

Next, the operation during an actual outgoing call will be described. FIG. 4 is a flowchart showing an operation procedure of the mobile device 7 in this embodiment. As in the first embodiment, it is assumed that the correct PIN is stored in advance in the memory 4 in the mobile device 7. When the user of the mobile device 7 turns on the power to use the mobile device 7, the processing unit 3 of the mobile device 7 first inputs the PIN manually from the operation unit 1 to the user of the mobile device 7. Request (step S3)
1). For example, in the case of a mobile device 7 equipped with an indicator,
It is conceivable to use a message display or the like on the display.

Thereafter, the processing unit 3 compares whether the PIN input by the user from the operation unit 1 and the contents of the PIN written in the memory 4 match (step S32). In the calling operation during the period after that, for example, until the power of the mobile device 7 is turned off, the automatic PIN sending operation is performed as in the first embodiment (step S33).
And the call starts.

If they do not match in step S32, the user of the mobile device 7 manually sets a PIN and sends this PIN to the base station 8 (step S3).
4). Specifically, the processing unit 3 of the mobile device 7 first requests the user of the mobile device 7 to manually input the PIN from the operation unit 1 by displaying a message on the display unit. The PIN input by the user is sent to the base station 8.

With such a control method, the correct PI
Since a user who does not know N cannot make outgoing call, it is possible to more effectively prevent unauthorized use by an unauthorized user.

Embodiment 5. In the fourth embodiment, when the power of the mobile device 7 is turned on, the user is prompted to input the PIN, and only when the input result matches the correct PIN stored in advance in the mobile device 7,
Although the subsequent automatic PIN sending operation was performed, the user may be allowed to input the lock secret code when the mobile device 7 is powered on, as shown in FIG. 5, and the same effect is obtained.

Next, the operation during an actual outgoing call will be described. FIG. 5 is a flowchart showing an operation procedure of the mobile device 7 in this embodiment. It is assumed that the correct lock personal identification number is previously stored in the memory 4 in the mobile device 7. When the user of the mobile device 7 turns on the power to use the mobile device 7, the processing unit 3 of the mobile device 7 first manually gives the lock personal identification number to the user of the mobile device 7 from the operation unit 1. Request to input (S41). this is,
For example, in the case of the mobile device 7 equipped with a display device, it is possible to use a message display or the like on the display device.

Thereafter, the processing unit 3 compares whether or not the content of the lock personal identification number input by the user from the operation unit 1 and the memory 4 is matched (step S42). ), In the subsequent calling operation in the period until the power supply of the mobile device 7 is turned off only when they match, the PIN automatic sending operation (step S43) is performed as in the first embodiment, and the call is started. If they do not match in step S42, the user of the mobile device 7 manually sets the PIN and sends the PIN (step S44). Specifically, the processing unit 3 of the mobile device 7
First, the PIN from the operation unit 1
Is requested by manually displaying a message on the display, and the PIN input by the user in response to the request is sent to the base station 8.

With such a control method, the correct PI
Since a user who does not know N cannot make outgoing call, it is possible to more effectively prevent unauthorized use by an unauthorized user.

Sixth Embodiment In the fourth embodiment, when the power of the mobile device 7 is turned on, the user is prompted to input the PIN, and only when the input result matches the correct PIN stored in advance in the mobile device 7,
Although the subsequent automatic PIN sending operation was performed, the security PIN may be input by the user when the power of the mobile device 7 is turned on, as shown in FIG. 6, and the same effect is obtained.
The content of the processing in this embodiment is written in the security code input from the operation unit 1 and the memory 4 by requesting the security code input when the mobile device 7 is powered on (step S51). This is different from the previous embodiment in that the processing unit 3 compares whether or not the content of the security code number is matched (step S52). The other processing is the same as that of the previous embodiment, and thus the description thereof is omitted.

As described above, even in the case of the second to sixth embodiments, it is determined that the mobile device 7 itself is stolen or that there is an unauthorized mobile device 7 in which the above-mentioned various authentication codes are copied. In this case, it is needless to say that the authentication function on the system can be maintained because unauthorized use can be prevented by changing the PIN on the control side.
