And a prohibition means for performing the operation.
[0011]
That is, the mobile device to which the present invention is applied has a built-in memory for storing personal use information (for example, telephone directory information and received e-mail), and the user can store the personal use information stored in the memory in a predetermined manner. Display output can be performed by operation. In such a mobile device, when the position registration request unit requests the management device of the mobile communication network to perform position registration for the current position of the mobile device, the determination unit manages whether or not the requested position registration is successful. The determination is made based on the response from the device. Here, if it is determined that the location registration has not been successful, for example, if the mobile device is located outside the range of the management device, or the use of the mobile device has been stopped by a user request due to loss or the like, the management device has been stopped. When the user authentication cannot be performed normally, the prohibition unit prohibits the display output of the personal use information stored in the memory.
[0012]
As a result, when the location registration is not successful, the display output of the personal use information stored in the memory is automatically prohibited.

[0026]
FIG. 1 shows a configuration of a communication system 1 of the present embodiment. As shown in the figure, the communication system 1 of the present embodiment includes mobile devices 10 and 20 and a management device 30 connected to the mobile communication network N for performing location registration of each mobile device and managing location information. It is configured. The mobile device 10 is located within the area of the nearest base station 40, and the mobile device 20 is located outside the area of the nearest base station 40.
[0027]
Next, the hardware configuration of each mobile device will be described with reference to FIG. Since each mobile device has the same configuration, the mobile device 10 will be described as an example. As shown in FIG. 1, the mobile device 10 includes a CPU 10A, a memory 10B such as an EEPROM (Electrically Erasable and Programmable ROM), a wireless communication device 10C wirelessly connectable to the mobile communication network N, and an input device such as operation buttons. 10D, a display device 10E such as an LCD (Liquid Crystal Display) or EL (Electro Luminescence), and an audio processing device 10F such as a microphone and a speaker. These components are connected via a bus 10G and are mutually connected. Data can be transmitted and received.
[0028]
Next, a functional block configuration of the mobile device 10 and the management device 30 will be described with reference to FIG. As shown in FIG. 1, the mobile device 10 requests the management device 30 to perform a location registration for the current location of the mobile device 10 and a memory 14 storing personal use information (for example, telephone directory information and received e-mail). A location registration requesting unit 11 for determining whether the location registration requested by the location registration requesting unit 11 has succeeded based on a response from the management device 30; And prohibiting means 13 for prohibiting display output of the personal use information stored in the memory 14 when it is determined that there is no personal use information.
[0029]
It should be noted that the CPU 10A of FIG. 2 plays these roles for the position registration requesting unit 11, the determination unit 12, and the prohibiting unit 13, and the memory 10B of FIG. The mobile device 20 in FIG. 1 also has the same configuration as the mobile device 10 described above.
[0030]
On the other hand, the management device 30 includes a request receiving unit 31 that receives a position registration request from the mobile device 10, and a position registration management unit that attempts to register the position of the mobile device 10 when the position receiving request is received by the request receiving unit 31. 32, a response unit 33 for returning a response corresponding to the trial result to the mobile device 10, a location registration database 34 storing location registration information on the location-registered mobile device, and a regular service that can use the mobile communication service. And an authentication database 35 in which authentication information relating to the mobile device is stored.
[0031]
In the location registration database 34, while the user of the mobile device has stopped using the service due to the loss of the mobile device, etc., the location registration information relating to the mobile device is not newly registered (that is, registration is rejected). I do. Although the details will be described later, the location registration management unit 32 refers to the location registration database 34 to confirm that the mobile station 10 can perform location registration when trying to perform a new location registration of the mobile station 10. It is assumed that the mobile station 10 refers to the authentication database 35 to confirm that the mobile station 10 is a legitimate mobile station that can use the mobile communication service.
[0032]
Next, the operation according to the present invention will be described with reference to FIGS. FIG. 4 is a sequence diagram showing the operation when the location registration of the mobile device is successful, and FIG. 5 is a sequence diagram showing the operation when the new location registration of the mobile device is rejected.
[0033]
The operation when the location registration is successful as shown in FIG. 4 is as follows. First, the mobile device 10 transmits a location registration request to the management device 30 (S1). Thereby, the management device 30 receives the location registration request from the mobile device 10 via the mobile communication network N, and refers to the location registration database 34 so that the mobile device 10 can perform location registration (that is, use the service). Is not stopped) (T1).
[0034]
When the use of the service of the mobile device 10 is not stopped and the confirmation that the location registration of the mobile device 10 is possible is completed, the management device 30 transmits an authentication request to the mobile device 10 (T2). Upon receiving the authentication request from the management device 30, the mobile device 10 returns an authentication response including authentication information unique to the mobile device 10 (for example, identification information and a password of the mobile device 10) to the management device 30 ( S2).
[0035]
Upon receiving the authentication response, the management device 30 matches the authentication information included in the authentication response with the authentication database 35 in FIG. 3 to confirm that the mobile device 10 is a valid mobile device that can use the mobile communication service. Confirm (T3). Here, when it is confirmed that the mobile device 10 is a legitimate mobile device that can use the mobile communication service, the management device 30 performs location registration indicating that the location registration for the mobile device 10 has been completed normally. A response is returned (T4). Thus, the location registration of the mobile device 10 ends normally.
[0036]
On the other hand, as shown in FIG. 5, the operation when the new location registration is rejected is as follows. It is assumed that the user of the mobile device 10 has stopped using the service of the mobile device 10 due to loss or the like, and the location registration database 34 stores information indicating that location registration of the mobile device 10 is not possible.
[0037]
First, the mobile device 10 transmits a location registration request to the management device 30 (S11). Thereby, the management device 30 receives the location registration request from the mobile device 10 via the mobile communication network N, and refers to the location registration database 34 so that the mobile device 10 can perform location registration (that is, use the service). Is not stopped) (T11).
[0038]
However, since a new location cannot be registered for the mobile device 10 in the location registration database 34, the management device 30 cannot confirm that the mobile device 10 can perform the location registration. Therefore, the management device 30 returns a location registration rejection response to the mobile device 10 (T12).
[0039]
Then, upon receiving the rejection response from the management device 30, the mobile device 10 automatically prohibits the display output of the personal use information in the memory 14 of FIG. 3 (S12). Specifically, the display output of the personal use information can be prohibited by a method of locking reading of the personal use information from the memory 14 or a method of deleting the personal use information from the memory 14.
[0040]
In FIG. 5, as a case where the location registration is rejected, a case where the user of the mobile device 10 has stopped using the service due to loss or the like and a new location registration of the mobile device 10 cannot be performed in the location registration database 34 will be described. However, the same operation as in FIG. 5 is performed in the following cases. That is, (1) the case where the mobile device 20 located outside the area of the nearest base station 40 shown in FIG. 1 requests the location registration, and (2) the case where the authentication cannot be confirmed by the management device 30, similarly to FIG. The display output of the personal use information in the memory can be prohibited, and the same effect can be obtained.
[0041]
By the way, if the location of the mobile device 10 has already been registered when the user of the mobile device 10 stops using the service, the location registration database 34 stores the location registration information of the mobile device 10. Confirmation of the location registration database 34 by the management device 30 in response to the location registration request from the mobile device 10 is a normal confirmation completion result. That is, the position registration process itself is normally performed.
[0042]
However, when the user of the mobile device 10 stops using the service due to loss or the like, a call rejection response is returned to the call request from the mobile device 10 by a service management device (not shown) in the network N. . Therefore, in addition to the case where the location registration is not successful, the mobile device 10 receives the call rejection response from the network N in response to the call request from the mobile device 10 and receives the personal use information in the memory 14. It is desirable to prohibit display output.
[0043]
That is, as shown in FIG. 6, if the location of the mobile device 10 has already been registered before the user who has lost the mobile device 10 notifies the communication company of the suspension of the service, the management device 30 of T4 sends The process proceeds in the same manner as in FIG. 4 until the location registration response. However, when the mobile device 10 makes a call request (S3), a call rejection response is returned from the network N to the mobile device 10 to stop using the service. (R1). Here, the mobile device 10 can automatically prohibit the display output of the personal use information in the memory 14 in conjunction with the reception of the call rejection response (S4).
[0044]
As described above, in the present embodiment, when the location registration of the mobile device is not successful (for example, when the mobile device is located outside the service area and there is no need to see the telephone directory information, In the case where the use has been stopped by the user request and the user authentication cannot be performed normally by the management device, and the location of the mobile device has already been registered before the user notifies the communication company of the suspension of the use of the service. However, the display output of the personal use information stored in the memory is automatically prohibited, so that there is no need for the mobile device user to input a specific destination number or the like from another terminal. The confidentiality of the contents of the memory of the mobile device can be improved without increasing the complexity of the operation.
[0045]
Lastly, a mobile device control program according to the embodiment of the present invention will be described. The mobile device control program is recorded on, for example, a computer-readable storage medium. Here, the recording medium causes a change state of energy such as magnetism, light, electricity, or the like to occur in a reading device provided in a hardware resource of a computer in accordance with a description content of a program, and the recording medium corresponds to the change state. It is capable of transmitting the description content of the program to the reading device in the form of a signal. As such a recording medium, for example, an IC (Integrated Circuit) card, a magnetic disk, an optical disk, a CD-ROM, etc., which are detachably mounted on a computer (including a mobile device), and fixedly attached to the computer A non-volatile semiconductor memory such as a built-in HD (Hard Disk) or integrally fixed firmware corresponds to this.
[0046]
Further, the program may be configured such that part or all of the program is received and stored by a mobile device according to the present invention from another device via a transmission medium such as a communication line. Further, the program may be transmitted from the mobile device according to the present invention to another mobile device via a transmission medium and installed.
[0047]
