The corresponding content name is deleted from. Further, as described above, the body data of the downloaded content is stored in the content storage area 409b of the mobile phone 40 to which the UIM 50 was attached at the time of download.

This U is stored in the subscriber information storage area 504c.
As the subscriber information of the owner of the IM 50, a subscriber ID, a credit card number, a bank account number, history information regarding outgoing and incoming calls, telephone directory information, and the like are stored. The UIM 50 is stored in the UIM ID storage area 504d.
The UIMID assigned to is stored. Note that the subscriber ID such as a telephone number is assigned to the owner of the UIM 50 by the telecommunications carrier according to the subscription contract for the communication service by the UIM 50, and the subscriber information storage area 504.
It is stored in c. The UIMID is, for example, UIM.
It is written in the UIMID storage area 504d at the time of factory shipment of 50 or at the time of contracting a communication service by the UIM 50.

The CPU 505 is a ROM 502 or an EEPR.
By executing various programs stored in the OM 504, each unit of the device connected via the bus 506 is controlled. The CPU 505 is, for example, the UI.
It controls communication with the mobile phone 40 to which the M50 is attached. Further, when the UIM 50 is attached to the mobile phone 40 and the main power of the mobile phone 40 is switched on, the CPU 505 causes the liquid crystal display screen of the mobile phone 40 to display a password input screen, and prompts the user to do so. Prompt for password. Then, the CPU 505 authenticates whether or not the user is the owner of the UIM 50 by comparing the password input by the user with the password registered in the EEPROM 504 in advance, and stores the subscriber information according to the authentication result. Access from the mobile phone 40 to the subscriber information and the like stored in the area 504c is restricted. The above is the configuration of the communication system 1 according to the present embodiment.

[A-2. Operation of First Embodiment] Next, the operation of the present embodiment will be described. In the following description of the operation, JavaAP is downloaded as content to the mobile phone 40 in which the UIM 50 is installed, and the JavaAP
The case where is executed according to the operation input will be described.

<1. Download Process> FIG. 7 is a sequence chart illustrating the operations of the content server 10, the mobile phone 40, and the UIM 50 when the mobile phone 40 downloads the JavaAP from the content server 10. First, the user attaches the UIM 50 to the mobile phone 40 and operates the operation input unit 402 of the mobile phone 40 to instruct the activation of the Web browser. As a result, in the mobile phone 40, the contents server 1
It is possible to display a WWW page provided from 0 on the display screen. Then, when the user gives an instruction to download the JavaAP by an operation input while browsing the WWW page provided from the content server 10, the download process shown in the figure is started.

First, the CPU 410 of the mobile phone 40
The download request is transmitted to the content server 10 via the wireless communication unit 401 (step S101). This download request includes a command for instructing the download and information for specifying the JavaAP to be downloaded. This download request is transmitted to the content server 10 via the mobile packet communication network 30 and the Internet 20. Upon receiving the download request from the mobile phone 40, the content server 10 reads the JavaAP designated by the download request from the memory (step S102) and transmits this JavaAP to the mobile phone 40 (step S103).

The JavaAP downloaded to the mobile phone 40 will be described in detail. First, the mobile phone 4
The ADF of JavaAP is transmitted from the content server 10 to 0. The CPU 410 of the mobile phone 40 confirms the contents of the received ADF and then, based on this ADF,
Send an AR file download request. In response to this, the content server 10 transfers to the mobile phone 40 Java A
P's JAR file is downloaded.

Next, the CPU 410 of the mobile phone 40
Is the UI stored in the UIMID storage area 409a.
MID, that is, the mobile phone 40 at the present time
The UIM ID of the UIM 50 attached to the is acquired (step S104). Incidentally, when the UIM 50 is mounted on the mobile phone 40, the UIMID of the mounted UIM 50 is stored in the UIM ID storage area 409a.
Is stored. And CPU410 is step S1.
UIMID acquired in 04 was downloaded
The content is stored in the content storage area 409b in association with the JavaAP (step S105).

In step S105, the CPU 41
The process executed by 0 will be described in detail. First, the CPU 4
10 is a content storage area 409b according to JAM.
The storage area for the Java AP downloaded this time is allocated to each of the JAR storage and the scratch pad in the above. Then, the CPU 410, according to JAM,
The downloaded JAR file of JavaAP is installed in the JAR storage, and the ADF and UIMID of this JavaAP are stored in the content storage area 409b in association with the JAR file.

Thereafter, the CPU 410 of the mobile phone 40
Identifies the downloaded Java AP, eg J
Get the file name (content name) of the AR file,
This content name is transmitted to the UIM 50 via the UIM interface 404 (step S106). UIM
When the CPU 505 of 50 receives the content name from the mobile phone 40 via the external interface 501,
This content name is added to the content list 504b in the EEPROM 504 to add the content list 504b.
Is updated (step S107). And the CPU 50
5 transmits an update completion notification indicating that the content list 504b has been updated to the mobile phone 40 (step S108).

<2. JavaAP Execution Process> Next, JavaAP executed by CPU 410 in mobile phone 40
The execution process 1 will be described with reference to the flowchart shown in FIG. The JavaAP execution process 1 is executed by the CPU 410 as a function of JAM when an operation command instructing execution of JavaAP is input.

First, the CPU 410 executes the Ja specified for execution.
The UIM ID associated with the vaAP is acquired from the content storage area 409b (step S201). As described above, the UIMID acquired in step S201 is the UI attached to the mobile phone 40 when the execution-designated JavaAP is downloaded.
This is the UIM ID of M50. Then, the CPU 410
UIMI stored in the UIMID storage area 409a
D, that is, the UIMID of the UIM 50 currently attached to the mobile phone 40 is acquired (step S202).

The CPU 410 then executes the above step S
201 and two UIMIs acquired in S202
D is collated (step S203), and it is determined whether or not the two UIMIDs match (step S204). That is, the CPU 410 compares the UIMID of the UIM 50 currently mounted on the mobile phone 40 with the UIMID of the UIM 50 currently mounted on the mobile phone 40 at the time of downloading the execution-designated JavaAP. Java using mobile phone 40
It is determined whether or not the user who gives an instruction to execute the AP is the user who downloaded this Java AP from the content server 10.

As a result, the CPU 410 has two UIMs.
If it is determined that the IDs do not match (step S2
04: No), the execution of JavaAP is canceled (step S205). Next, the CPU 410
Canceled execution of P and its reason, this Java A
If P is desired to be used, the content server 10 is officially downloaded, and guidance information therefor is displayed on the display screen (step S206).
The JavaAP execution process 1 ends.

On the other hand, the CPU 410 has two UIMIDs.
When it is determined that the two match (step S204: Ye
s), that is, it is determined that the user who has instructed to execute the JavaAP is a user who has downloaded this JavaAP from the content server 10 and who is officially authorized to provide and use the content by the content provider. In this case, execution of JavaAP is permitted (step S207). Then, the CPU 410 activates the JavaAP designated for execution (step S208), and starts processing based on this program.

As described above, according to this embodiment,
The mobile phone 40 uses the JavaAP downloaded from the content server 10 as a UIM50 attached to the mobile phone 40 at the time of downloading the JavaAP.
Can be restricted to the owners of.

[B. Second Embodiment] In the first embodiment, the use of the Java AP downloaded to the mobile phone 40 is changed to the use of the mobile phone 4 when the Java AP is downloaded.
The case has been described in which only the owner of the UIM 50 attached to 0 is restricted. In the present embodiment, a configuration will be described in which the content provider can specify whether or not to limit the users of Java AP. In addition, in this embodiment, the same reference numerals are used for the same parts as those in the first embodiment. The description of the parts common to the first embodiment will be omitted.

FIG. 9 shows Ja used in this embodiment.
It is a figure which illustrates the data structure of ADF of vaAP. AD
F is a text file in which various control information for controlling installation and activation of the JAR file, network access, etc. is described. In the figure,
The "item name" column describes the name of the control information, and the "mandatory / optional" column indicates whether the corresponding control information is essential control information for the ADF or a control that is not essential but is included in the ADF as an option. It is shown whether it is information.

Here, each control information will be briefly described. "AppName" is the name of JavaAP and "AppVer" is Jav.
The version of the aAP, "PackageURL" is a URL (Uniform Resource Loc) indicating the download source of the JAR file.
ator). Further, "AppSize" is the size (data amount) of the JAR file, and "Spsize" is the size of the scratch pad used by JavaAP.

Then, the "AppUser" indicates that the use of JavaAP should be ignored when the JavaAP is downloaded.
This is control information that specifies whether or not to limit only the owner of the UIM 50 that has been attached to the UIM 50, and “1” or “0” is stored as data. In this specification, AppUser
Setting the value of to "1" indicates the use of JavaAP
This indicates that only the owner of the UIM 50 attached to the mobile phone 40 at the time of downloading the JavaAP is restricted. Also, setting the value of AppUser to "0" does not limit the use of JavaAP to only the owner of the UIM 50 attached to the mobile phone 40 at the time of downloading this JavaAP, that is, for any user. It indicates that the use of this Java AP is permitted.

The value of this AppUser is set by the content provider that provides the JavaAP. That is, the content provider can set the use restriction of the JavaAP provided by itself by the AppUser in the ADF. For example, a content provider may want to use JavaAP that a wide variety of people want to use for free.
The AppUser of the ADF may be set to "0", while the AppUser of the ADF may be set to "1" for the Java AP or the like that wants to collect the usage fee from each user.

As described above, in the present embodiment, the ADF includes the AppUser designating whether or not to restrict the users of the JavaAP, and the JavUser according to the AppUser and the UIMID.
It is different from the above-described first embodiment in that the availability of execution of aAP is determined.

FIG. 10 shows the mobile phone 4 according to this embodiment.
6 is a flowchart illustrating an operation of JavaAP execution processing 2 executed by a CPU 410 at 0. This Ja
The vaAP execution processing 2 is Ja in the above-described first embodiment.
Similar to the vaAP execution process 1, when an operation command instructing the execution of JavaAP is input, CP is provided as a function of JAM.
It is executed by U410.

First, as shown in FIG.
0 reads the ADF of the Java AP specified to be executed from the content storage area 409b, and reads Ap from the ADF.
The value of pUser is acquired (step S301). Then
The CPU 410 determines whether the value of AppUser is “1”,
That is, it is determined whether or not to limit the users of the Java AP whose execution is designated (step S302).

As a result, the CPU 410 determines that the value of AppUser is "1" and the execution-designated JavaAP is used.
When it is specified to limit to only the owner of the UIM 50 attached to the mobile phone 40 at the time of downloading the JavaAP (step S302: Yes), the processes shown in steps S303 to S310 are executed.
The processes of steps S303 to S310 are the same as the processes of steps S201 to S208 of the JavaAP execution process 1 (see FIG. 8) in the above-described first embodiment, and thus detailed description thereof will be omitted, but the outline thereof is as follows. On the street.

That is, the CPU 410 associates with the Java AP designated for execution, and stores it in the content storage area 409.
By collating the UIMID stored in b with the UIMID stored in the UIMID storage area 409a, the user who is currently instructing to execute the JavaAP using the mobile phone 40 uses this JavaAP as the content. It is determined whether or not the user is the user downloaded from the server 10, and whether or not the JavaAP can be executed is determined according to the determination result.

On the other hand, the CPU 410 executes the above step S3.
02, when the value of AppUser is “0” and it is specified that the use of the execution-designated Java AP is not limited to only the owner of the UIM 50 attached to the mobile phone 40 at the time of downloading this Java AP. (Step S302: No), this Ja
Since the use of vaAP may be permitted, the UIMID collation is not performed, and the process proceeds to step S309. And
The CPU 410 permits execution of JavaAP (step S
309), start this Java AP (step S31
0), start processing based on this program.

As shown in FIG. 9, since AppUser is an option in the ADF, the above step S3
In 01, when the CPU 410 acquires the value of AppUser from the ADF, it is possible that there is no AppUser in the ADF. In addition, if the content is an existing content (JavaAP), the Ap file in the ADF is rewritten unless the ADF is rewritten.
pUser does not exist. When it is detected that AppUser is not included in the ADF, the CPU 410 determines that Ja
From the perspective of protecting the license rights of vaAP, Ap
Assuming that the value of pUser is "1", step S303
Perform the following processing. That is, when there is no AppUser in the ADF, the user of the JavaAP is the UIM attached to the mobile phone 40 when the JavaAP is downloaded.
It works by limiting it to only 50 owners and protecting the right to license this Java AP.

As described above, according to this embodiment,
Based on the value of AppUser in the ADF, the mobile phone 40 determines whether or not the use of the JavaAP downloaded from the content server 10 is restricted only to the owner of the UIM 50 attached to the mobile phone 40 at the time of downloading the JavaAP. To decide. Therefore, the content provider can easily set the usage restriction of the JavaAP provided by the content provider.

[C. Third Embodiment] In the first and second embodiments described above, the UIM 50 is mounted and the mobile phone 4 is mounted.
The user using 0 cannot know which Java AP can be used for each Java AP downloaded to the mobile phone 40 by instructing execution by operation input. Therefore, in the present embodiment, a mobile phone 40 will be described in which the user can recognize the Java AP that the user can use even when the execution is not instructed. The hardware configurations of the mobile phone 40 and the UIM 50 according to the present embodiment are the same as those of the mobile phone 40 and the UIM 50 according to the above-described first embodiment, and thus the description thereof will be omitted.

When the user wants to use any Java AP downloaded to the mobile phone 40, the user displays the Java AP selection screen on the display screen by operating input. In response to the input of the command instructing the display of the JavaAP selection screen, the CPU 410 of the mobile phone 40 executes the selection screen display process 1 shown in FIG. As shown in the figure, first, the CPU 410 of the mobile phone 40.
Is each Ja stored in the content storage area 409b.
The vaAP is specified (step S401), and the content name (for example, JAR
Get the file name of the file). Then CPU4
10 acquires the UIMID stored in the UIMID storage area 409a, that is, the UIMID of the UIM 50 currently mounted on the mobile phone 40 (step S402).

Then, the CPU 410 executes the above step S
For each Java AP specified in 401, the Java A
The UIMID stored in the content storage area 409b in association with P is collated with the UIMID acquired in step S402 (step S40).
3). Based on this collation result, the CPU 410 causes each Java A
For each P, it is possible to determine whether the user who is currently using the mobile phone 40 is the user who has downloaded this Java AP from the content server 10.

Next, the CPU 410 causes the above step S
For each Java AP specified in 401, the Java A
The value of AppUser in the ADF of P is acquired (step S404). Depending on the value of this AppUser, CPU410
For each Java AP, the use of the Java AP is
It is possible to determine whether or not the PIM is limited to only the owner of the UIM 50 attached to the mobile phone 40 when the P is downloaded.

After that, the CPU 410 causes the above step S
Based on the UIMID matching result in 403 and the value of AppUser acquired in step S404,
Each Java A for users using the mobile phone 40
Whether or not P can be used is determined (step S405). Specifically, the CPU 410 sets the JavaAP whose UIMID associated with the JavaAP matches the UIMID acquired in step S402 among the JavaAPs identified in step S401, and sets the value of AppUser to "0". The set Java AP and mobile phone 40
A Java AP that may be permitted to be used by a user who is using, and other Java APs are not permitted to be used.

In this way, the CPU 410 allows the user using the mobile phone 40 to use each JavaAP stored in the content storage area 409b Ja.
After selecting vaAP and J avaAP that does not permit the use, the use is permitted, for example, as shown in FIG.
JavaAP content name and JavaAP that is not allowed to be used
The content name is displayed on the display screen in a display mode different from that of the content name (step S406).

Here, in the screen display example shown in FIG. 12, the content name (program name) of the Java AP which is permitted to be used is shown in a larger and bold font than the content name of the Java AP which is not permitted to be used. However, in practice, it is preferable to display the content name of the Java AP that is allowed to be used and the content name of the Java AP that is not allowed to be used, for example, with different display colors of the content name and its background color. Further, the method of changing the display form may be, for example, a form in which a mark indicating that the content can be used is displayed beside the content name for which the use is permitted. Further, only the content name of the JavaAP that is permitted to be used may be displayed, or further, only the content name of the JavaAP that is permitted to be used may be notified to the user by a voice message.

When the user selects the content name of the Java AP which is permitted to be used on the selection screen shown in FIG. 12 by the operation input, the CPU 410 activates the selected Java AP and executes the processing based on this program. To start. On the other hand, in the selection screen shown in FIG. 12, when the content name of JavaAP which is not allowed to be used is selected by the operation input, the CPU 410 selects it.
A message indicating that the use of this Java AP is not permitted and that this Java AP is to be officially downloaded from the content server 10 is displayed on the display screen without executing the Java AP. In addition, Ja that the user is not allowed to use
Regarding the vaAP, of course, the user cannot instruct the execution of this Java AP, but the owner of the mobile phone 40 is designed so as to instruct to delete (uninstall) the Java AP from the content storage area 409b. ing.

As described above, according to this embodiment,
The user can know the Java AP that can be used by the user for each Java AP that the UIM 50 is downloaded to the detachable mobile phone 40 at a stage where the execution is not instructed.

In the selection screen display process 1 shown in FIG. 11, U is used to determine the availability of JavaAP.
It was configured to use IMID and AppUser, but UIMID
Alternatively, the content list 504b stored in the UIM 50 may be used. Below,
3, using the content list 504b, Java
The operation when determining whether or not the AP can be used will be described. Note that the description of the part that performs the same processing as the selection screen display processing 1 shown in FIG. 11 will be simplified.

First, the CPU 410 of the mobile phone 40
Each Java A stored in the content storage area 409b
While specifying P (step S501), a content name is acquired for each specified Java AP. Then
The CPU 410 communicates with the UIM 50 via the UIM interface 404 and acquires the content list 504b from the UIM 50 (step S50).
2). The contents list 504b is the first list described above.
As described in the embodiment, it is a list showing a list of contents downloaded by the owner of the UIM 50 using the mobile phone 40 wearing the UIM 50.

Next, the CPU 410 causes the above step S
The content name of each Java AP identified in 501 is compared with each content name in the content list 504b acquired in step S502 (step S503). As a result, the CPU 410 causes each Java
For each AP, the user using the mobile phone 40
It is possible to determine whether or not the user has downloaded the JavaAP from the content server 10.

Next, the CPU 410 causes the above step S
For each Java va specified in 501, the Java
The value of AppUser in the ADF of the AP is acquired (step S504). After that, the CPU 410 compares the collation result with the content list 504b in step S503 and the AppUse acquired in step S504.
Based on the value of r, the availability of each JavaAP for the user who is using the mobile phone 40 is determined (step S505). Specifically, the CPU 410 selects Ja from among the JavaAPs identified in step S501.
The JavaAP whose content name of vaAP matches any one of the content names in the content list 504b acquired in step S502, and the value of AppUser is "0".
The Java AP set to 1 is a Java AP that may be permitted to be used by the user who is using the mobile phone 40, and the other Java APs are Java APs that are not permitted to be used.

In this way, the CPU 410 permits the user using the mobile phone 40 to use each Java AP stored in the content storage area 409b Ja.
After selecting between vaAP and JavaAP that is not allowed to be used,
As shown in FIG. 12, the content name of the Java AP that is permitted to be used and the content name of the Java AP that is not permitted to be used are displayed on the display screen in different display modes (step S
506). As described above, the content list 50 stored in the UIM 50 is used instead of the UIM ID.
4b may be used to determine the availability of JavaAP.

[D. Fourth Embodiment] The above-described first to third
In the embodiment, Ja downloaded to the mobile phone 40 is used.
The UIMID is used to limit the users of the vaAP. In this case, for example, if the UIM 50 of the user is replaced with a new UIM 50 due to malfunction or replacement, it becomes impossible to properly limit the users of the JavaAP (contents). Therefore, in the present embodiment, a mobile phone 40 will be described in which the user of the content can be appropriately restricted even when the user replaces the UIM 50. The hardware configurations of the mobile phone 40 and the UIM 50 according to the present embodiment are the same as those of the mobile phone 40 according to the first embodiment described above.
Since it is the same as the UIM 50, the description thereof will be omitted.

When the user who is using the UIM 50 replaces the owned UIM 50 with a new UIM 50 due to malfunction or replacement, the user first goes to a service shop and offers the clerk to replace the UIM 50.
The store clerk prepares the replacement UIM 50 after concluding a contract regarding the replacement of the UIM 50 with the user. In addition, the user can use the mobile phone 40 and the UI that he or she is using.
Give the M50 to the clerk. In the description below, the UIM 50 before the replacement is the “old UIM 50” and the UIM 5 after the replacement is the same.
0 is described as "new UIM50".

Upon receipt of the mobile phone 40 and the old UIM 50 from the user, the store clerk first mounts the old UIM 50 on the mobile phone 40. Next, the store clerk operates the mobile phone 40 to shift to the maintenance mode, and the UIM5
Instruct execution of UIM exchange processing for performing processing relating to 0 exchange.

FIG. 14 shows the mobile phone 4 according to this embodiment.
10 is a flowchart illustrating an operation of UIM exchange processing executed by the CPU 410 at 0. As shown in the figure, first, the CPU 410 causes the UIMID stored in the UIMID storage area 409a, that is,
The UIMID of the old UIM 50 currently attached to the mobile phone 40 is acquired, and this UIMID is stored in the non-volatile memory 409 (step S601). Also, CPU
410 is the content list 504b from the old UIM50.
And the subscriber information stored in the subscriber information area 504c are acquired and stored in the non-volatile memory 409 (step S602).

Next, the CPU 410 causes the mobile telephone 40
Power off once and replace old UIM50 with new UIM50
Then, a message prompting the user to turn on the power again is displayed on the display screen (step S603). According to this message, the clerk turns on the power of the mobile phone 40.
After FF and replacing the old UIM50 with the new UIM50,
When the power is turned on again, the CPU 410 displays the UIMID
The UIMID stored in the storage area 409a, that is, the UIMID of the replaced new UIM50 is acquired (step S604).

Thereafter, the CPU 410 causes the above step S
Old UI stored in non-volatile memory 409 at 501
The UIMID of M50 is read (step S605).
Then, the CPU 410 sets the UIMID of the old UIM 50 to the new UI out of the UIMIDs stored in the content storage area 409b in association with the content, for example.
Rewrite to the UIM ID of M50 (step S60

After storing in M504, the storage completion notification is sent to the mobile phone 40.
Send to. After completing the UIM exchange process described above,
The store clerk returns the mobile phone 40 and the new UIM 50 to the user.

As described above, according to this embodiment,
The mobile phone 40 has a UIMID associated with the content downloaded from the content server 10.
The UIMI of the old UIM50 according to the replacement of the UIM50.
Rewrite from D to UIMID of new UIM50. Therefore, if the user operates UIM5
Even if 0 is exchanged, the content downloaded to the own mobile phone 40 using the old UIM 50 can be continuously used in the new UIM 50. In addition,
In the present embodiment, for example, a malicious user may be the U of another person.
From the viewpoint of preventing fraudulent activities such as copying the content list 504b and subscriber information stored in the IM 50 to another UIM 50, the UIM exchange process is performed by the clerk of the service shop, not by the user. However, by incorporating a personal authentication function or the like, the user may be allowed to perform work related to UIM exchange processing.

Further, the UIM exchange process may be activated as described below. First,
At the service shop, the clerk signs a UIM50 replacement contract with the user and then replaces the UIM50.
Prepare 50. In addition, the user hands the mobile phone 40 and the UIM 50 used by the user to the clerk. After this, the store clerk has a UIMID of the old UIM 50 and a new UIM
The contract information relating to the exchange of the UIM 50 including the 50 UIM IDs is transmitted from the communication terminal installed in the service shop to the service management center (not shown) of the telecommunications carrier operating the mobile packet communication network 40. Further, the clerk wears the old UIM 50 on the mobile phone 40.

After confirming the contract contents sent from the service shop, the service management center issues a start command for instructing the start of the UIM exchange process via the mobile packet communication network 40 to the mobile phone 4 to which the old UIM 50 is attached.
