DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of a mobile communication terminal and a mobile communication terminal control method according to the invention will be described in detail with reference to the accompanying drawings. In addition, the same code | symbol shall be used for the same element and the overlapping description is abbreviate | omitted.
[0020]
[First Embodiment]
FIG. 1 is a schematic configuration diagram showing a mobile communication terminal 1 of the present embodiment, and FIG. 2 is a perspective view of the mobile communication terminal 1. The mobile communication terminal 1 transmits and receives communication signals to and from a base station (not shown), and is configured to be able to execute an application that handles an electronic value having a monetary / economic value.
[0021]
The mobile communication terminal 1 stores an OS (Operating System) for executing basic functions as a mobile phone and an OS for executing an application using electronic value information. An OS related to the former basic function is stored in the memory 11, and an OS related to the latter application is stored in the memory 21. The housing of the mobile communication terminal 1 includes two electrically connected IC chips, the memory 11 is mounted on the first IC chip 10, and the memory 21 is the second IC chip 20. It is mounted on. In addition to the memory 11, the first IC chip 10 includes a wireless unit 15 and an image processing unit 16. Further, the first IC chip 10 includes an input unit 30 for inputting various information such as a telephone number of a destination and a mail message, a speaker 40 for outputting the voice of the other party, and own voice. A microphone 50 or the like for inputting is electrically connected.
[0022]
The mobile communication terminal 1 incorporates a UIM (User Identification Module) 12 in which subscriber information is stored. The UIM 12 can be attached to and detached from the main body of the mobile communication terminal 1. In this embodiment, the UIM 12 can be inserted from a slot on the side of the main body. The UIM 12 attached to the mobile communication terminal 1 is connected to the first IC chip 10 so that information communication is possible.
[0023]
The UIM 12 includes a subscriber information memory 13 in which subscriber information such as a subscriber's telephone number and a password used for an authentication procedure, and availability information regarding availability of the application are stored, and control that controls the UIM 12. Part 14 is provided. The personal identification number used for the authentication procedure is generally called a PIN (Personal Identification Number). The UIM 12 is in a state where the information in the subscriber information memory 13 can be used when the user is authenticated by inputting the correct PIN.
[0024]
The radio unit 15 transmits / receives a signal to / from the antenna 70, and in order to establish a call, the radio unit 15 modulates / demodulates the signal, encodes the audio signal input from the microphone 50, and outputs the audio from the speaker 40. Various well-known functions such as composite reception signals are realized. The image processing unit 16 controls the display screen of the display 60 in accordance with an instruction from the OS in the memory 11.
[0025]
The memory 11 of the first IC chip 10 is provided with a second IC chip control unit 17. The second IC chip control unit 17 controls the operation of the second IC chip 20. On the other hand, an application management unit 24 is provided in the memory 21 of the second IC chip 20. The application management unit 24 stores one or a plurality of applications that use the electronic value information. Such an application may be installed before the mobile communication terminal 1 is delivered to the user, or may be installed by the user using the Internet or the like. In the present embodiment, it is assumed that three types of application 1 using a movie ticket, application 2 using a concert ticket, and application 3 using an electronic commuter pass are stored as electronic values.
[0026]
As already described above, the subscriber information memory 13 of the UIM 12 stores availability information indicating whether each application can be used. FIG. 3 is a data table showing the availability information stored in the subscriber information memory 13. The availability information of the applications 1 and 3 is “Active”, which indicates that these applications can be used. On the other hand, the availability information of the application 2 is “Non-Active”, which indicates that the application cannot be used. The mobile communication terminal 1 is configured such that an application whose availability information is “Non-Active” cannot be executed, and an application whose “Active” is “executable” can be executed.
[0027]
The availability information is, for example, from “Active” to “Non-Active” or from “Non-Active” to “Non-Active” by an instruction signal transmitted from the service provider that provides the application to the mobile communication terminal 1 through the base station. It is switched to “Active”. Specifically, for example, the instruction signal sent from the service provider to change from “Active” to “Non-Active” reaches the second IC chip control unit 17 via the antenna 70 and the radio unit 15. The second IC chip control unit 17 that has received the signal accesses the control unit 14 of the UIM 12 and changes the availability information stored in the subscriber information memory 13 from “Active” to “Non-Active”.
[0028]
For example, when the mobile communication terminal is lost or stolen, the user notifies the service provider of the application of the change in the availability information from “Active” to “Non-Active”. It is carried out by doing. Or, when a service provider has made it clear that a user who has once granted permission to use the application is an unauthorized user, such as having caused some problem (for example, financial trouble), the application cannot be used. Also implemented.
[0029]
On the other hand, the change in the availability information from “Non-Active” to “Active” occurs when a lost mobile communication terminal is discovered and returned to the user's hand, or when the service provider has been regarded as an unauthorized user. This is implemented when the application can be used for some reason (for example, when a usage fee for an application that has been delinquent is paid).
[0030]
In addition, the change of the availability information may not be performed by a radio signal, but a person in charge such as a service provider may switch the availability information by operating the input unit 30. In this case, in order to prevent an operation by a person who is not authorized to switch the availability information, it is preferable that a person in charge, such as a service provider, inputs a password when switching the availability information.
[0031]
In addition, the second IC chip 20 is provided with an external interface 22 that transmits and receives electronic value information to and from an external reader / writer in addition to the above-described memory 21 in which a dedicated OS is stored. The external interface 22 can correspond to IrDA, Bluetooth, or the like.
[0032]
The above is the configuration of the mobile communication terminal 1 of the present embodiment. Next, a method for controlling the mobile communication terminal 1 will be described with reference to the flowchart of FIG.
[0033]
Here, a case where a movie ticket is used as an electronic value will be described. The applications stored in the mobile communication terminal 1 and the availability information are as shown in FIG. The movie ticket availability information is set to Active when the mobile communication terminal 1 purchases a movie ticket on the Internet, for example. When one movie ticket is purchased, the electronic value information stored in the mobile communication terminal 1 is information indicating the value of one movie ticket, and when two movie tickets are purchased, the value of two tickets is given. It becomes information to show.
[0034]
First, when a user who visits a movie theater directs the external interface 22 of the mobile communication terminal 1 to a reader / writer installed at an entrance gate, the external interface 22 sends a request for reading electronic value information transmitted from the reader / writer. Receive (S101).
[0035]
In the mobile communication terminal 1 that has received the request, the application management unit 24 of the second IC chip 20 transmits the application 1 of the application 1 to the UIM 12 through the first IC chip 10 before starting the application 1 related to the movie ticket. Inquires about availability information (S102).
[0036]
In the UIM 12 inquired in this way, the control unit 14 accesses the subscriber information memory 13 and confirms whether the availability information of the application 1 is “Active” or “Non-Active”. Then, as shown in FIG. 3, since the availability information of the application 1 regarding the movie ticket is “Active”, the process proceeds to S104.
[0037]
In S104, the control unit 14 of the UIM 12 transmits information indicating that the application 1 is available to the second IC chip control unit 17, and the second IC chip control unit 17 that has received the information receives the second IC chip. The application 1 stored in the application management unit 24 of the chip 20 is activated. Then, in response to the request in S101, the activated application 1 transmits electronic value information, that is, information having a movie ticket value to the entrance gate reader / writer (S105). Upon receiving this electronic value information, the reader / writer multiplexes and verifies the information, and if it is determined that it corresponds to a genuine movie ticket, the entrance gate opens and the user can enter the movie theater.
[0038]
Here, the application 1 whose availability information is “Active” has been described as an example. However, when the availability information is “Non-Active”, the following processing is executed. Hereinafter, application 2 related to the concert ticket shown in FIG. 3 is taken as an example.
[0039]
For example, when the user visits a concert venue and points the external interface 22 of the mobile communication terminal 1 to a reader / writer installed at the entrance gate, the same processing as in S101 and S102 described above is performed. That is, the application management unit 24 of the second IC chip 20 inquires the UIM 12 through the first IC chip 10 about availability information of the application 2 regarding the concert ticket.
[0040]
Then, in S103, since the availability information of the application 2 is determined as “Non-Active”, the process proceeds to S106, and the display 60 displays that the application cannot be executed. Specifically, the image processing unit 16 operates to display, for example, “The concert ticket application cannot be executed” on the display 60. In this case, the application 2 is not executed, and the user cannot enter the concert hall.
[0041]
As described above, in the present embodiment, the availability information indicating whether or not the application relating to the electronic value information can be used is stored in the UIM 12, and this availability information is set to indicate that the application cannot be used ( In the present embodiment, “Non-Active”) prevents unauthorized use of the electronic value information. Accordingly, it is possible to prevent the abuse of electronic value information due to theft of the mobile communication terminal and the use of the electronic value information by an unauthorized user who does not want the service provider to use the electronic value information for some reason.
[0042]
Further, according to the present embodiment, the following effects can also be obtained. That is, some users wish to change the housing of the mobile communication terminal in a relatively short period of time when they are tired of the design of the mobile communication terminal. Furthermore, when changing the housing, the user tends to change only the design while retaining basic information such as his / her telephone number and mail address. In addition, even when a mobile communication terminal having a new function appears, there are users who want to change the mobile communication terminal to use the function. In the mobile communication terminal 1 of the present embodiment, the UIM 12 in which subscriber information including basic information is stored is used. By setting this UIM 12 in another mobile communication terminal, the user can make a previous subscription. A new mobile communication terminal can be used while continuing to use the user information.
[0043]
For this reason, the user installs the UIM 12 that has been used so far on a new mobile communication terminal in order to continue using the subscriber information. Since the information is stored, even if a user who is set in a state where the application cannot be executed attaches the UIM to another mobile communication terminal, the application still cannot be executed. That is, even if the mobile communication terminal is replaced, as long as the user continues to use the same UIM 12, an application whose availability information is “Non-Active” cannot be executed. Thereby, use of the electronic value information by an unauthorized user can be suppressed.
[0044]
In the present embodiment, the availability information of each of the plurality of applications is managed by the UIM 12. As a result, the service provider of the application can manage whether or not the user is allowed to use the plurality of applications separately at the mobile communication terminal 1. Of course, when a plurality of applications are stored in the application management unit 24, the availability information may be created for a batch of these applications. That is, when the availability information is “Active”, all applications can be executed. On the other hand, when the availability information is “Non-Active”, all applications cannot be executed.
[0045]
[Second Embodiment]
Next, a second embodiment of the mobile communication terminal and the mobile communication terminal control method according to the present invention will be described with reference to the flowchart shown in FIG. In addition, the component of the mobile communication terminal 1 of this embodiment is the same as that of 1st Embodiment.
[0046]
This embodiment differs from the first embodiment in that when an electronic value information request is received from a reader / writer such as a movie theater (S101), the application is executed without checking the availability information stored in the UIM 12 This is the point (S102). However, the application is only executed at this stage, and the electronic value information is not transmitted to the requesting read / write.
[0047]
Next, the application management unit 24 of the second IC chip 20 inquires of the UIM 12 through the first IC chip 10 about the availability information of the application for which the electronic value information acquisition request is made (S103). If the availability information stored in the UIM 12 is determined to be “Active” in S104, the process proceeds to S105, and the electronic value information of the application is transmitted to the read / write.
[0048]
On the other hand, if it is determined in S104 that the availability information of the application requested to acquire electronic value information is “Non-Active”, the process proceeds to S106, and the display 60 displays that the application cannot be executed.
[0049]
As described above, in the present embodiment, when an electronic value information acquisition request is received from the outside, the application is once started regardless of the contents of the availability information in the UIM 12, and the availability information is “Active”. The electronic value information is transmitted only to the request destination, and in the case of “Non-Active”, the information is not transmitted to the request destination.
[0050]
According to this embodiment, similarly to the first embodiment, unauthorized use of electronic value information can be prevented. Furthermore, even when a user who does not want to use the electronic value information changes the housing of the mobile communication terminal, when the user attaches the UIM 12 to a new mobile communication terminal, the user continues to use the electronic value information. Can be deterred.
[0051]
As mentioned above, although the invention made by the present inventors has been specifically described based on the embodiments, the present invention is not limited to the above embodiments. For example, the number of applications stored in the application management unit may be only one instead of a plurality.
[0052]
【The invention's effect】
As described above, according to the mobile communication terminal and the mobile communication terminal control method according to the present invention, unauthorized use of electronic value information can be prevented, and a user who does not want to use electronic value information changes the terminal. Even in this case, use by the user can be suppressed.
