Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile phone with an additional function.
[0002]
[Prior art]
In recent years, mobile phones having additional functions such as cameras and games have been developed. In addition, a mobile phone having a function capable of reliably restricting photographing in a specific photographing restriction region has been developed (see, for example, Patent Document 1). For these mobile phones, the introduction cycle of new models is short, and in order to promote subscription to mobile phones, old model mobile phones are sold at low prices ignoring cost costs. The mobile phone can communicate according to a contract with a telecommunications carrier. If this contract is canceled, communication cannot be performed.
By the way, in a mobile phone having an additional function, it is possible to use the additional function even if communication is not possible. In such a case, if you cancel the contract immediately after purchasing an old model mobile phone, you can obtain a unit that realizes the additional function at a lower price than purchasing the equivalent of the additional function alone. End up. For this reason, there was a problem that the manufacturer could not recover the capital invested in the technology development.

[0028]
Next, the operation of the mobile phone 300 when the communication contract is canceled will be described with reference to the flowchart of FIG.
The user who cancels the contract of the mobile phone 300 contacts the communication carrier T, and cancels the contract through a predetermined procedure. When the management server T2 confirms that the procedure for canceling the contract is completed (step S1), it is determined whether or not the user's mobile phone 300 is within the reach of radio waves (step S2). Here, when the management server T2 confirms that the mobile phone 300 is within the reach of radio waves, in other words, when the management server T2 is not out of service area (step S2; NO), the base station T1 provides communication restriction information for restricting communication. This is transmitted to the user's mobile phone 300 (step S3). On the other hand, when the management server T2 confirms that the mobile phone 300 is not within the reach of radio waves, in other words, when the management server T2 is out of the service area (step S2; YES), the management server T2 continues until the mobile phone 300 enters the service area. stand by. When the communication control unit 2 receives the communication restriction information (step S4), the control unit 1 stores, for example, an operation invalid flag as a restriction flag to that effect in the flag storage area 32 in the memory 3 (step S5).
As described above, in order to cancel the contract, in addition to the user applying for the contract cancellation to the telecommunications carrier T, it is necessary for the telecommunications carrier T to forcibly cancel the contract due to the delinquency of the user's communication charges or unauthorized use. If this happens, the communication control unit 2 may receive the forced use prohibition information transmitted by the communication carrier T by the same means. Further, the contract cancellation information by the user's intention and the forced contract cancellation information from the communication carrier T may be the same.
[0029]
Next, the operation when using the mobile phone 300 whose contract has been canceled will be described with reference to the flowchart of FIG.
First, the control unit 1 determines whether or not the user has pressed the input unit 5 of the mobile phone 300 (step S21). Here, when the control unit 1 determines that the user has pressed the input unit 5 of the mobile phone 300 (step S21; YES), the control unit 1 executes the determination program 36a to store the flag storage area 32. It is determined whether or not an operation invalidation flag is stored (step S22). On the other hand, if the operation invalid flag is not stored in the flag storage area 32 (step S21; NO), the control unit 1 repeats this process until the input unit 5 is pressed.
If the operation invalidation flag is stored in the flag storage area 32 (step S22; YES), the control unit 1 executes the use restriction program 36b to set the operation invalidation flag to ON and the camera unit of the input unit 5 200 is prohibited (step S23). Here, the use restriction program 36b prohibits input of a key switch for camera operation such as imaging and reproduction, prohibits transmission of a control signal to the control unit 8 of the camera unit 200, and transmits to the camera unit 200, for example. The operation of the camera unit 200 is restricted, for example, by prohibiting the power supply. In addition, the control unit 1 causes the display unit 6 to display the content of the use prohibition of the camera unit 200, for example, “cannot be used because the contract has been canceled” (step S24).
[0030]
Next, the operation when using only the camera unit 200 when the main unit 100 receives the communication restriction information and the use of the main unit 100 and the camera unit 200 is prohibited will be described with reference to the flowchart of FIG. To do.
A user who wishes to use the camera unit 200 inserts the memory card 19 storing the release program 20 for invalidating the operation invalidation flag into the reading unit 18 of the main body unit 100 and causes the control unit 1 to recognize the memory card 19 (step S31). When the control unit 1 recognizes the memory card 19 (step S32), the control unit 1 causes the release program 20 stored in the memory card 19 to be executed (step S33). When the control unit 1 executes the release program 20, the control unit 1 invalidates the operation invalid flag in the flag storage area 32 (step S34).
The cancellation program 20 may be an algorithm that stops execution when the number of times of imaging by the camera unit 200 reaches a predetermined number of times and prohibits the use of the camera unit 200 again. An algorithm may be used in which the execution is stopped when the period reaches a predetermined period, and the use of the camera unit 200 is prohibited again. In addition, the memory card 19 can be distributed for a fee by the communication carrier T, or in the case of a card that restricts the number of use and the period of use. Can be reflected.
[0031]
Thus, according to the mobile phone 300 of the present embodiment, when the use of the main body unit 100 is restricted by the control unit 1 executing the use restriction program 36b, by executing the release program 20, The use restriction of the camera unit 200 is released. In other words, the use restriction program 36b and the cancellation program 20 allow the use of the main unit 100 to cancel or default on the contract (for example, a communication contract from the telecommunications carrier T side for reasons such as non-payment of communication charges or unauthorized use). In addition to being able to restrict the use of the camera unit 200 in the case of being restricted by (forcibly released), the camera unit 200 can be removed by inserting the memory card 19 into the reading unit 18 and releasing the use restriction. Can be used. Therefore, when the user who cancels the communication contract wants to use only the camera unit 200, the manufacturer can respond to the user's needs by providing the memory card 19 in which the cancellation program 20 is stored. Of course, when the memory card 19 is provided, by charging the user, it is possible to reflect the cost of product development without detriment to the manufacturer.
Further, when the memory card 19 is attached to the reading unit 18 and the release program 20 stored in the memory card 19 is read by the reading unit 18, the use of the camera unit 200 is based on the release program 20 read by the reading unit 18. The restriction is lifted. Therefore, the release program 20 itself can be used as release information, and unauthorized use release of the camera unit 200 can be prevented.
[0032]
[Second Embodiment]
Next, a second embodiment of the mobile phone with an additional function according to the present invention will be described in detail. Note that the second embodiment will be described only for parts different from the first embodiment, and the other parts will be denoted by the same reference numerals and description thereof will be omitted.
[0033]
As shown in FIG. 6, a camera-equipped cellular phone (hereinafter referred to as a cellular phone) 400 can communicate by using radio waves having a predetermined frequency transmitted from a base station T1 of a communication carrier T. ing. The communication carrier T includes a management server T2 that stores personal information and telephone numbers of users who have signed a communication contract, and manages the cancellation of the contract with the user. The management server T2 includes a network T3. Via the communication terminal P of the agency D. Here, the agency D is a place entrusted to the communication carrier T to perform a procedure for concluding a contract related to communication or canceling the contract. The communication terminal P is a terminal that is provided in the agency D and performs rewriting of settings when the model of the mobile phone 400 is changed between the management server T2 and the mobile phone 400.
[0034]
Note that the management server T2 and the communication terminal P of the agency D may be connected by wire or may be connected wirelessly via the base station T1 used during communication.
In the program area 36 of the cellular phone 400, as shown in FIG. 7, in addition to the programs of the first embodiment, a release program for releasing the use restriction when the use of the camera unit 200 is restricted. 36e is stored. The unlocking program 36e is locked so that, for example, the control unit 1 cannot be executed unless a password is input from the input unit 5, and the lock is released by inputting a predetermined password. It is configured.
In addition, the mobile phone 400 is provided with a connection portion 17 for connecting to the main body portion 1 with the communication terminal P and the cable C. The connection unit 17 is connected to the cable C using, for example, an external device connection terminal used for charging, but any method can be used as long as it can communicate with the communication terminal P.
[0035]
Next, the operation of the mobile phone 400 when the communication contract is canceled will be described with reference to the flowchart of FIG.
The user who cancels the contract of the mobile phone 400 goes to the agency D, plugs the cable C into the connection unit 17, and connects the mobile phone 400 to the communication terminal P (step S41). Next, by operating the communication terminal P, the communication terminal P transmits communication restriction information to the mobile phone 400 via the cable C (step S42). When the communication control unit 2 of the mobile phone 400 receives the communication restriction information (step S43), the control unit 1 stores this in the flag storage area 32 in the memory 3 as an operation invalid flag as a restriction flag (step S44). ).
[0036]
Next, the operation when using the mobile phone 400 whose contract has been canceled will be described with reference to the flowchart of FIG.
First, the control unit 1 determines whether or not the user has pressed the input unit 5 of the mobile phone 300 (step S51). Here, when the control unit 1 determines that the user has pressed the input unit 5 of the mobile phone 300 (step S51; YES), the control unit 1 executes the determination program 36a to store the flag storage area 32. It is determined whether or not an operation invalid flag is stored (step S52). On the other hand, if the operation invalid flag is not stored in the flag storage area 32 (step S51; NO), the control unit 1 repeats this process until the input unit 5 is pressed.
If an operation invalidation flag is stored in the flag storage area 32 (step S52; YES), the control unit 1 executes the use restriction program 36b to turn on the operation invalidation flag, and the camera unit of the input unit 5 The use of 200 is prohibited (step S53). Moreover, the control part 1 displays the use prohibition content of the camera part 200 on the display part 6 (step S54).
[0037]
Next, an operation when only the camera unit 200 is used when communication restriction information is received and use of the main body unit 100 and the camera unit 200 is prohibited will be described with reference to the flowchart of FIG. In the second embodiment, a method for canceling the use restriction of the camera unit 200 by inputting release information from the input unit 5 will be described as an example.
A user who desires to use the camera unit 200 inputs a personal identification number as release information described in the prepaid card 29 obtained in advance from the input unit 5 (step S61). The control unit 1 transmits and authenticates the input personal identification number to the base station T1 (step S62). If the personal identification number is correct (step S62; YES), the controller 1 locks the release program 36e in the program area 36. Unlocking is performed (step S63), and the release program 36e is executed (step S64). On the other hand, if the code number is incorrect (step S62; NO), the control unit 1 displays on the display unit 6 that the code number is incorrect (step S65), and returns to step S61 again.
When the control unit 1 executes the release program 36e, the control unit 1 invalidates the operation invalidation flag in the flag storage area 32 (step S66).
[0038]
As described above, according to the mobile phone 400 of the present embodiment, when the use of the main unit 100 is restricted by the control unit 1 executing the use restriction program 36b, the release program 36e uses the camera unit 200. Remove the restriction. That is, the use restriction program 36b and the release program 36e are provided so that the use of the camera part 200 can be restricted when the use of the main body part 100 is restricted due to the cancellation or non-performance of the contract. The camera unit 200 can be used by inputting and canceling the use restriction. Therefore, when the user who cancels the communication contract wants to use only the camera unit 200, the manufacturer can respond to the user's needs by providing the prepaid card 29 in which the personal identification number is described. Note that the password may be acquired from a site such as the communication carrier T. The personal identification number may be acquired directly from the host computer of the communication carrier T connected to the connection unit 17 via the network. Of course, when the password is obtained, the user is charged so that it can be reflected in the product development cost recovery without penalizing the manufacturer.
Further, when a password is input from the input unit 5, this password cancels the use restriction of the camera unit 200. Therefore, the use restriction of the camera unit 200 can be released by a very simple method, and a mobile phone with an additional function that can be easily used by the user can be provided.
[0039]
The present invention is not limited to the above embodiment. For example, a time measuring unit for measuring time is provided in the main body 100, and when the unused time of the main body 100 has elapsed for a predetermined time, a restriction flag is stored in the flag storage area 32, and the user performs communication to perform restriction. It is good also as a structure which cancels | releases a flag. In this case, since the communication cannot be performed if the communication contract remains released, the restriction flag cannot be released, and the camera unit 200 cannot be used unless re-contracted. Further, if the communication contract is not cancelled, the restriction flag is canceled by performing communication, so that the camera unit 200 can be used again.
With this configuration, it is not necessary to receive communication restriction information about whether or not the user's contract is valid from the telecommunications carrier T, so the telecommunications carrier T can change the system such as the management server T2. Mobile phone 300, 400 can be made simpler.
[0040]
Further, when the use of the communication function is restricted, it may be not only when the contract is canceled but also when the memory 3 is rewritten when the model is changed. Further, in the above embodiment, the imaging function by the camera unit 200 is prohibited, but music playback or game playback may be prohibited. Further, the memory 3 may be built in the mobile phones 300 and 400, or may be constituted by a memory card that can be attached to and detached from the mobile phones 300 and 400.
Further, by selling the storage medium such as the memory card 19 in which the cancellation program 20 is stored and the mobile phone 300 as a set or separately sold, the use of the camera unit 200 after the cancellation of the communication contract can be prevented.
In the above embodiment, image data, music data, and game data are collectively managed. However, they can be managed individually, and any function may be used arbitrarily.
In addition, the present invention can be freely changed and improved without departing from the gist of the invention.
