Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a communication system 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 appropriate. A call establishment system for establishing a call, which relates to a mobile communication system that prevents unauthorized use of the first communication device.

[0002]

[Prior art]

Conventional example 1. FIG. 7 is a block diagram showing a configuration of a conventional mobile communication system. In FIG. 7, reference numeral 1 denotes an operation unit represented by, for example, a keyboard for a user to operate the mobile unit 7 of the mobile communication system, 2 denotes a control unit that controls the entire mobile unit 7 of the mobile communication system, 3 Is a processing unit represented by an MCU that performs various control processes, 4 is a memory,
Denotes a high-frequency circuit unit, and 6 denotes 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 denotes a base station that communicates with the mobile device 7.

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

[0004] In order to prevent unauthorized use, the mobile station 7 of a general mobile communication system stores both the subscription information and the individual authentication information for each mobile station 7 in the memory 4 inside the mobile station 7. The same authentication information is stored on the control side. When a call is made, the processing unit 3 of the mobile station reads the information from the memory 4 during the period from the call to the start of the call, and transmits 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 registered properly. That is, a method has been adopted in which the authentication of the mobile device 7 is performed to prevent illegal use of the mobile device 7 on the system. However,
Since the authentication information stored in the memory 4 inside the mobile device 7 cannot be changed, if the same information as the storage information inside the mobile device 7 is copied to another mobile device 7 once, Just like that, it can be used in the system.
Therefore, such authentication for each mobile device 7 cannot necessarily exclude use of an unauthorized mobile device 7.

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

[0006] Such an authentication code for authenticating the user of the mobile station 7 is generally a Parsonal Identificati
It is called on Number (abbreviation is PIN). If this authentication method using a PIN is used together, for example, even when the above-mentioned individual authentication information for each of the subscription and the mobile device 7 is copied to another mobile device 7, the personal user of the mobile device 7 changes the PIN. By doing so, illegal use of the mobile device 7 can be easily eliminated.

[0007]

In the mobile communication system according to the prior art 1, since the authentication information stored in the memory 4 inside the mobile device 7 cannot be changed, the same information as the stored information inside the mobile device 7 is different. Once copied to the mobile device 7, the mobile device 7 can be used in the system just like the normal mobile device 7. Therefore, such authentication for each mobile device 7 has a problem that unauthorized use of the mobile device 7 cannot always be excluded. Further, in the mobile communication system according to the second conventional example, the user of the mobile device 7 needs to use the operation unit 1 to input a PIN every time a call is started. For this reason, the operation procedure up to the start of the call was complicated and very troublesome for the user. Further, erroneous input of a PIN occurs due to a complicated operation procedure, and in this case, a call cannot be started and a call fails.

The present invention has been made to solve such a problem, and has as its object to eliminate illegal use more effectively.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. Hereinafter, a communication system according to this embodiment will be described. FIG. 1 is a flowchart showing an operation procedure of the communication system according to this embodiment. The configuration of the communication system according to this embodiment is the same as the block diagram shown in FIG. In this specification, the base station 8 shown in FIG.
A control station (not shown) that controls the base station 8 is collectively referred to as a control side. However, the mobile device 7 according to the present embodiment operates the PI by the user operating the operation unit 1.
It has a function that the user can freely determine N and the determined PIN can be stored in the memory 4 in the mobile device 7.

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

Next, the operation at the time of an actual outgoing call will be described. It is assumed that the PIN is stored in the memory of the mobile device 7 by the user in advance 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 when the user presses the off-hook button and enters the telephone number of the other party. In FIG. 1, first, a process of starting to establish 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 device 7 determines the timing of sending the PIN, reads out the PIN stored in the memory 4, and
The read PIN is controlled to be automatically transmitted to the base station 8 via the high frequency circuit 5 (step S2).
Thereafter, the control side including the base station 8 determines whether the PIN transmitted from the mobile device 7 matches the PIN stored in advance by the control side (step S3). If the PIN transmitted from the mobile device 7 matches the PIN stored on the control side, a communication path for the mobile device 7 is secured (step S4). When a call path is established,
A call by the user of the mobile device 7 becomes possible (step S).
5). On the other hand, if the PIN transmitted from the mobile device 7 does not match the PIN stored on the control side, the base station 8 refuses to start the call (step S6).

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

The P stored in the memory 4 of the mobile unit 7
Since IN can be changed by the user, if the mobile device 7 itself has been stolen, or if it is determined that there is an unauthorized mobile device 7 to which the above-described various authentication codes have been copied, the mobile device 7 is moved. The user of the device 7 changes the PIN stored in the memory 4 and performs the process of changing the PIN on the control side, thereby preventing subsequent unauthorized use. The presence of the fraudulent mobile device 7 is recognized when a fee is charged higher than the legitimate user actually uses.

The PIN has been described as being freely determined by the user of the mobile station 7. However, if a restriction is made so that no two or more mobile stations 7 having the same PIN exist in the system, the following is possible. This is advantageous. That is, the same P
If there are two or more mobile devices 7 having IN in the system, it can be recognized that one of them has been used illegally. Since this recognition can be performed on the control side, it is effective when the authorized user does not know the existence of the unauthorized user.

In this embodiment, the case where a call is made from the mobile device 7 has been described, but the present invention can be applied to other cases. For example, if a PIN is transmitted when there is an incoming call to the mobile device 7, it is possible to prevent an unauthorized user from receiving a call to the mobile device 7. If the user forgets the PIN, the user can use the mobile device 7 by changing the PIN.

Further, in this embodiment, a case has been described in which the processing for establishing the communication path is performed by software, but the same processing may be performed by hardware. That is, it can be realized by providing a means for executing the above steps. This is the same in 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. However, the present invention can be applied to other communication modes. For example, the present invention can be applied to a method of establishing a call between the mobile devices 7. The mobile device 7 and the base station 8 in this embodiment are examples of a communication device. In this regard, the same applies to the following embodiments.

Embodiment 2 In the above-described embodiment, the user has previously stored the PIN in the mobile device 7 and automatically transmitted the PIN when necessary. However, the lock function of the mobile device 7 itself and the PIN By automatically controlling the automatic transmission operation, unauthorized use in the case of theft can be more efficiently prevented.

Here, the lock function is for preventing the telephone from functioning at all even if the power of the telephone is turned on. Therefore, in the locked state, all functions of the mobile device 7 are stopped, so that a call cannot be made and a call cannot be made. This function is a function for preventing an accidental use such as improper use in the case of a theft or an unnecessary accident such as unnecessarily paying a telephone charge due to a child's mischief. In order to release the locked state, it is necessary to input a password for unlocking which is stored in the memory 4 in advance.

Next, the operation of this embodiment will be described.
The configuration of the communication system according to this embodiment is the same as that shown in FIG. FIG.
7 is a flowchart showing this embodiment, in which the same parts as those in FIG. 7 are denoted by the same reference numerals. When the calling process is started by the user of the mobile device 7 performing the calling operation, the processing unit 3 of the mobile device 7 first starts the current call after the power of the mobile device 7 is turned on. By this time, it is determined whether or not the correct lock password has been input (step S1).
1). Specifically, whether the password input by the user from the time when the power of the mobile device 7 is turned on until the start of the current call matches the password for locking stored in the memory 4 in advance. Determine whether or not. Then, it selects whether to execute steps S12 to S13 or to execute steps S14 to S16 according to the determination result.

If the input password is correct, the mobile station 7 starts a communication path start establishment process (step S1).
2) Automatically send out the PIN stored in advance in the mobile device 7 (step S13). If the entered personal identification number is incorrect, the mobile device 7 starts a communication path establishment process (step S14), and then issues a request from the operation unit 1 to input a PIN. This request is made by displaying the request on the display of the mobile device 7. When the user inputs a PIN using 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 device 7 matches a 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 they match, processing for starting a call between the mobile device 7 and the base station 8 is performed (step S18), and the call is started (step S19). On the other hand, if the PIN transmitted from the mobile device 7 does not match the PIN registered on the control side, the base station 8 refuses to start the call (step S110).

The above process is executed every time the calling process is started, regardless of whether the mobile device 7 is locked or not. Also, if the correct lock PIN has been entered between the time the power is turned on and the call processing is performed, there is no need to enter the PIN after the start of the call. Becomes possible. Further, if the correct lock PIN has not been input after the power is turned on and the call processing is performed, the operation is performed so as to input the PIN from the operation unit 1, so that the correct lock PIN is input. Correct PIN even if you did not enter
You can talk if you know it.

As described above, when performing the calling process, the result of the determination as to whether or not the correct lock PIN has been input after the power of the mobile device 7 is turned on until the calling process is started. Accordingly, whether to retrieve the PIN from the memory 4 or to input the PIN from the operation unit 1 is determined, so that unauthorized use by an unauthorized user can be effectively prevented. That is, by monitoring the past input status, it is determined whether or not the user is a legitimate user. Confirm whether the user is a user and prevent unauthorized use more effectively.

Embodiment 3 In the above-described embodiment, the user has previously stored the PIN in the mobile device 7 and automatically transmitted the PIN when necessary. However, the security function of the mobile device 7 itself, By controlling the automatic transmission operation of the numbers in cooperation with each other, it is possible to effectively prevent unauthorized use in the case of theft.

Here, the security function prevents a specific function of the mobile device 7 from operating unless the user inputs a correct security password. By using this security function, for example, it is possible to receive an incoming call but not to transmit, to prevent a setting change of various passwords, to access private information stored in the mobile device 7. Can be prevented. By using this security function, unauthorized use by a third party can be more effectively prevented.

As in the case of the lock, the personal identification number for the security function is written in the memory 4 of the mobile device 7,
This can be realized by comparing the number input from the operation unit 1 and the password written in the memory 4 with the processing unit 3. The purpose of this is to prevent a user 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 according to this embodiment is the same as that shown in FIG. FIG.
5 is a flowchart showing this embodiment, in which the same parts are denoted by the same reference numerals and description thereof will be 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 current call after the power of the mobile device 7 is turned on. It is determined whether or not a correct security password has been input at least once before (step S21). More specifically, the security code input by the user from the time when the power of the mobile device 7 is turned on until the current call is started matches the security release code stored in the memory 4 in advance. It is determined whether or not to do. Then, steps S22 to S23 are executed according to the determination result, or steps S24 to S23 are executed.
26 is selected.

If the input password is correct, the mobile station 7 starts a communication path establishing process (step S22).
The PIN automatically stored in the memory 4 of the mobile device 7 is automatically transmitted (step S23). If the entered password is not correct, the mobile device 7 starts a communication path establishment process (step S24), and then the PIN is transmitted from the operation unit 1.
Make a request to enter This request is made by displaying the request on the display of the mobile device 7. When the user inputs a PIN using 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). If 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), a 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 refuses to start the call (step S210).

The above process is executed every time the calling process is started regardless of whether the mobile device 7 is in the security state or not. Also, if the correct security PIN has been entered between the time the power is turned on and the call processing is performed, there is no need to enter the PIN after the start of the call, so prompt calls can be made. Becomes possible.
Further, if the correct security PIN has not been input after the power is turned on and the call processing is performed, the operation is performed so as to input the PIN from the operation unit 1, so that the security PIN is input. If you do not, you can make a call if you know only the correct PIN.

As described above, when performing the calling process, it is determined whether or not the correct security PIN has been input from the time the power of the mobile device 7 is turned on until the calling process is started. Depending on whether the PIN is taken out of the memory 4 or
Since it is determined whether IN is to be input from the operation unit 1, unauthorized use by an unauthorized user can be effectively prevented. Further, the trouble of PIN input by the authorized user is also omitted. That is, by monitoring the past input status, it is determined whether or not the user is a legitimate user. Check if there is.

Embodiment 4 FIG. In the first embodiment, the mobile device 7 only automatically sends out the previously stored PIN number.
IN, and only when the input result matches the PIN stored in the predetermined mobile device 7, the subsequent P
An automatic transmission operation of IN may be performed, and illegal use in the event of wiretapping can be effectively prevented.

Next, the operation at the time of 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 the memory 4 in the mobile device 7 in advance. 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 inputs the PIN from the operation unit 1 to the user of the mobile device 7. Request (step S3
1). This is, for example, in the case of the mobile device 7 having a display,
It is conceivable to use a message display or the like on a display.

Thereafter, the processing unit 3 compares whether the PIN input by the user from the operation unit 1 and the content of the PIN written in the memory 4 match (step S32). For example, in the calling operation after that, for example, during the period until the power of the mobile device 7 is turned off, the PIN automatic transmission operation (step S33) as in the first embodiment
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 the 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 a PIN from the operation unit 1 by displaying a message on a display, and this request is issued. And sends the PIN input by the user to the base station 8.

With such a control method, the correct PI
Since a user who does not know N cannot make a call, unauthorized use by an unauthorized user can be prevented more effectively.

Embodiment 5 In the fourth embodiment, the user is required to input a PIN when the power of the mobile device 7 is turned on. Only when the input result matches the correct PIN stored in the mobile device 7 in advance, the subsequent PIN is changed. Although the automatic transmission operation was performed, as shown in FIG. 5, when the power of the mobile device 7 is turned on, the user may be required to input a password for locking, and the same effect is obtained.

Next, the operation at the time of 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 password has been stored in the memory 4 in the mobile device 7 in advance. 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 inputs the lock password from the operation unit 1 to the user of the mobile device 7. A request is made to input (S41). this is,
For example, in the case of the mobile device 7 equipped with a display, it is conceivable to perform the display using a message display or the like on the display.

Thereafter, the processing unit 3 compares whether or not the lock password input by the user from the operation unit 1 matches the contents of the lock password written in the memory 4 (step S42). Only when they match, in the subsequent calling operation during the period until, for example, the power of the mobile device 7 is turned off, the automatic PIN transmission operation (step S43) is performed as in the first embodiment, and the telephone conversation is started. If they do not match in step S42, the user of the mobile device 7 manually sets and transmits the PIN (step S44). Specifically, the processing unit 3 of the mobile device 7
First, the user of the mobile device 7 receives a PIN
Is displayed by displaying a message on a display to manually input the PIN, and the PIN input by the user is transmitted to the base station 8 in response to the request.

With such a control method, the correct PI
Since a user who does not know N cannot make a call, unauthorized use by an unauthorized user can be prevented more effectively.

Embodiment 6 FIG. In the fourth embodiment, the user inputs a PIN when the power of the mobile device 7 is turned on. Only when the input result matches the correct PIN stored in the mobile device 7 in advance, the subsequent PIN is changed. Although the automatic transmission operation has been performed, as shown in FIG. 6, the security password may be input by the user when the power of the mobile device 7 is turned on, and the same effect is obtained. The contents of the processing in this embodiment request the input of a security password when the power of the mobile device 7 is turned on (step S51), and are written in the memory 4 and the security password input from the operation unit 1. The processing unit 3 differs from the previous embodiment in that the processing unit 3 compares whether or not the contents of the security password number are the same (step S52). Other processes are the same as those in the above-described embodiment, and a description thereof will not be repeated.

As described above, even in the second to sixth embodiments, it is determined that the mobile device 7 itself has been stolen, or that there is an unauthorized mobile device 7 to which the various authentication codes described above have been copied. In this case, the unauthorized use can be prevented by changing the PIN on the control side, so that it goes without saying that the authentication function on the system is maintained.
