Description

  The present invention relates to a mobile communication terminal such as a mobile phone that can execute an application program.

  Conventionally, as this type of mobile communication terminal, a mobile phone capable of executing an application program written in an object-oriented programming language independent of a platform is known. For example, JAVA (registered trademark of Sun Microsystems, Inc., the same applies hereinafter) is known which has a virtual machine function and can execute an application program described in JAVA (Patent Document 1). reference). In such a mobile phone, by executing an application program, a standby screen composed of a three-dimensional video is displayed on the display of the mobile phone, a game or fortune-telling is performed on the mobile phone, and music is played back. be able to.

  A program execution environment (such as a JAVA virtual machine) for executing an application program reads data from a platform storage area (first storage means) managed by a mobile phone phone platform via the phone platform. It has a function for performing update processing such as processing or deletion, change, and addition. Therefore, some application programs are executed using data stored in the platform storage area using this function. For example, there is an application program that reproduces an incoming melody using incoming melody data downloaded by a user via a communication network and stored in a platform storage area.

  A program execution environment for executing such an application program needs to grasp in advance the storage contents of the platform storage area in order to perform read processing and update processing via the telephone platform. Therefore, the program execution environment performs processing for acquiring specific data for specifying data stored in the platform storage area at the start of execution of the application program. Specifically, taking the above-described application program for playing ringtones as an example, name data (specific data) of all ringtones stored in the platform storage area is acquired at the start of execution. Then, the program execution environment performs a storage process of storing the acquired name data in an application storage area (second storage unit) where the name data can be deleted, changed, and added. Thereafter, when the user selects a specific ringing melody by the user, the name is stored in the platform storage area via the telephone platform based on the name data related to the selection stored in the application storage area. A process for reproducing the incoming melody data corresponding to the data is performed.

JP 2000-347867 A

However, when the application program is executed using the data stored in the storage area for the platform based on the specific data after performing the storage process as described above, the following problem occurs.
That is, in general, the application program is automatically paused during execution, for example, when an incoming call is received or when another process such as mail transmission is performed. During the suspension, the stored data may be updated by the user when the data stored in the platform storage means is changed, deleted, or new data is added. If such an update is performed during a pause, the correspondence between the specific data in the application storage area and the data in the platform storage means will not match. As a result, there is a problem that the resumed application program may not operate properly. For example, in the case of the application program for playing the above-mentioned ringing melody, when the ringing melody data in the platform storage area is deleted during the pause, the name data corresponding to the deleted data is Exists in the storage area without being deleted. For this reason, the resumed application program may operate to reproduce ringtone melody data that has already been deleted and does not exist based on the name data. When new incoming melody data is added during the pause, name data corresponding to the added data does not exist in the application storage area. Therefore, the incoming melody data added during the pause cannot be played by the resumed application program.

Further, in the mobile phone described above, when the storage area for the platform is a storage means such as a memory card that can be attached to and detached from the mobile phone body, the storage means may be removed or a new storage means during the temporary suspension of the application program. Even when the device is mounted, there arises a problem that the application program cannot operate properly.
That is, for example, in the case of the application program for reproducing the above-mentioned ringing melody, when the user removes the storage means from the mobile phone body during the pause, the name data is not deleted in the application storage area. . For this reason, the resumed application program may operate to reproduce the incoming melody data in the storage means that has been removed based on the name data. In addition, when a new storage means is attached during the pause, there is no name data corresponding to the incoming melody data in the new storage means in the application storage area. Therefore, the incoming melody data in the new storage means replaced during the pause cannot be reproduced by the resumed application program.

In addition to the above ringtone melody data, data entered by the user (phone number data, e-mail address data, etc.), data obtained via a communication network (image data, ringtone melody data, etc.), etc. for platforms Some have been developed to execute application programs using data stored in a storage area. For example, an e-mail application program for transmitting an e-mail using e-mail address data stored in a platform storage area has been developed. When this application program is executed to send an e-mail, the above-described mobile phone performs a process of acquiring destination address data via the phone platform each time the e-mail is sent. This leads to processing delay. Therefore, when the data used by the application program is relatively small data such as destination address data, the data stored in the platform storage area is copied at the start of execution of the application program, and this is stored in the application storage area. It is desirable to perform storage processing stored in
However, when the data stored in the platform storage means is changed or new data is added during the suspension, duplicate data of the changed or added data does not exist in the application storage area. Therefore, the resumed application program cannot use the changed or added data, and there is a problem that the application program may not operate properly.

  On the other hand, when the application program is resumed, synchronization is performed so that the storage contents of the application storage area correspond to the storage contents of the platform storage area, and the attachment / detachment state of the storage means that can be attached to and detached from the mobile phone body is confirmed By doing so, the application program can be appropriately operated. However, in this case, every time the application program is restarted, the program execution environment needs to perform the synchronization process and the attachment / detachment state confirmation process. This results in a delay in the operation of the application program.

  The above-mentioned problem is not limited to the case where the update of the storage contents of the platform storage area or the attachment / detachment of the storage means that can be attached to and detached from the mobile phone body is performed during the suspension of the application program, but the case where the storage means is executed Can also occur in the same way. Moreover, although the above-described problem has been described by taking a mobile phone as an example, the same problem may occur in other mobile communication terminals.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a mobile communication terminal capable of appropriately operating an application program while minimizing a delay in the operation of the application program. Is to provide.

In order to achieve the above object, the invention of claim 1 includes a first storage means and a second storage means for storing data, and changing or deleting the data stored in the first storage means, Alternatively, update processing means for performing update processing for adding new data to the first storage means, and at least a part of the data stored in the first storage means are duplicated and stored in the second storage means Or the storage process for storing the specific data for specifying the data stored in the first storage means in the second storage means, and then using the copied data or A mobile communication terminal comprising program execution means for executing an application program using data stored in the first storage means specified by specific data, wherein the update processing means includes the storage processing Did If the program execution unit has performed the update process until the completion of the execution of the application program, it is characterized in sending a notification to that effect to said program execution means.
In this mobile communication terminal, the program execution means can recognize that the data stored in the first storage means has been updated by the notification sent from the update processing means. Therefore, the program execution means synchronizes the storage process, that is, the storage contents in the second storage means so as to correspond to the updated storage contents of the first storage means only when receiving this notification. Processing can be performed. Therefore, it is possible to minimize the number of times of the synchronization processing, and it is possible to minimize the delay of the operation of the application program. By performing such a synchronization process, the application program can be appropriately operated even when the storage content of the first storage unit is updated during the suspension of the application program. Whether or not to perform the synchronization process when receiving the notification depends on the contents of the application program executed by the program execution means.

The invention of claim 2 is the mobile communication terminal of claim 1, wherein the program execution means is specified before using the duplicated data or by the specific data when receiving the notification. The storage process is performed again before using the data stored in the first storage means.

At that time, the storage contents in the second storage means and the storage contents in the first storage means are always synchronized. Therefore, the application program can be appropriately operated.

According to a third aspect of the present invention, in the mobile communication terminal of the second aspect, the notification includes update data information for specifying data updated by the update process, and the program execution means Is characterized in that the storage process is performed only for data specified by the update data information.
In this mobile communication terminal, since only the updated data in the first storage means is synchronized with the storage contents in the second storage means, all the storage contents in the second storage means are synchronized. Compared with the case where it takes, the synchronization processing can be speeded up.

According to a fourth aspect of the present invention, there is provided a first storage means for storing data and detachably attached to the mobile communication terminal body; a second storage means for storing data; and the first storage means for storing the data. A recognizing means for recognizing the attachment / detachment state of one storage means and a storage process for copying at least a part of the data stored in the first storage means and storing it in the second storage means, or the first After performing the storing process for storing the specific data for specifying the data stored in the storage means in the second storage means, the first specified by using the duplicated data or by the specific data A mobile communication terminal comprising a program execution means for executing an application program using data stored in the storage means, wherein the recognition means performs the storage processing and then the program execution means The first storage means is removed from the mobile communication terminal main body or the first storage means is attached to the mobile communication terminal main body until the execution of the execution program is terminated. In this case, a notification indicating that is sent to the program execution means.
In this mobile communication terminal, the program execution means detects that the first storage means has been removed from the main body of the mobile communication terminal or that the first storage means has newly been moved by the notification sent from the recognition means. It can be recognized that it is attached to the communication terminal body. Therefore, the program execution means is, for example, when the first storage means is removed from the mobile communication terminal body only when the first storage means is notified that it has been removed from the mobile communication terminal body. For example, it is possible to perform processing such as issuing a warning to the user or temporarily stopping execution of the application program. Therefore, it is possible to minimize the number of times of this process, and it is possible to minimize the delay of the operation of the application program. Further, the program execution means, for example, stores the content stored in the second storage means only when it receives a notification that the first storage means is newly attached to the mobile communication terminal body. It is possible to perform a process of synchronizing so as to correspond to the stored contents of the means. Therefore, it is possible to minimize the number of times of the synchronization processing, and it is possible to minimize the delay of the operation of the application program. Since the storage contents of the second storage means can be always synchronized with the first storage means, the application program can be appropriately executed even when a new first storage means is mounted during temporary suspension of the application program. Can be operated.

According to a fifth aspect of the present invention, in the mobile communication terminal of the fourth aspect, the program execution means receives the notification indicating that the first storage means is attached to the main body of the mobile communication terminal. In this case, the storage process is performed again.
In this mobile communication terminal, the program execution means uses the replicated data in the second storage means or the data stored in the first storage means specified by the specific data in the second storage means. At that time, the storage contents in the second storage means and the storage contents in the first storage means are always synchronized. Therefore, the application program can be appropriately operated.

FIG. 8 is a flowchart showing a flow of processing for executing the application program in the first embodiment.
First, the user 1 downloads and acquires the music data used by the application program of the music player in advance by using a known method using the mobile phone 20 via a communication network, and registers this in the storage area for the platform. (S11). Specifically, for example, the user 1 operates a key on the operation unit 213 to access a server on a communication network that provides music data. As a result, a music data selection screen for selecting downloadable music data is displayed on the liquid crystal display 27. Then, on the music data selection screen, when the user selects music data desired by the scroll key 24 and presses the multi-function key 25, the main control unit 215 controls the data communication unit 212, and the music data Download. The music data downloaded in this way is stored in the platform storage area of the RAM 202 by the main control unit 215.

  Next, the user 1 downloads and acquires the application program of the music player from the download server 11, and registers it (S12). Specifically, the user 1 accesses the download server 11 by operating a key of the operation unit 213. As a result, a download selection screen for selecting a downloadable application program is displayed on the liquid crystal display 27. Then, on the download selection screen, when the application program of the music player to be executed is selected using the scroll key 24 and the multi-function key 25 is pressed, the main control unit 215 controls the data communication unit 212, and An application program is downloaded from the download server 11.

  Here, the application program in the first embodiment includes a JAD file (text data) that is property information and a JAR file (binary data) that is a program body. The JAD file includes application data, application version, application vendor name, basic data such as URL data where the JAR file is stored, and whether the application program has already been authenticated, or the application program is connected to the network. This includes setting data such as whether the application program is used in a state in which the application program is used or whether the application program is resident. When the application program of the music player to be executed is selected on the download selection screen, the main control unit 215 controls the data communication unit 212 and first downloads only the JAD file of the application program. Thereafter, the main control unit 215 reads URL data in which the JAR file is stored from the JAD file, accesses the URL, and downloads the JAR file. The application program composed of the JAD file and the JAR file downloaded in this way is stored in the RAM 102 by the main control unit 215.

  When executing the application program downloaded in this manner, the user 1 operates the keys of the operation unit 213 to display an application selection screen for selecting an application program to be executed on the liquid crystal display 27. When the application program of the music player to be executed is selected on the application selection screen using the scroll key 24 and the multi-function key 25 is pressed, the telephone platform shown in FIG. 7, that is, the main control shown in FIG. The application program execution instruction is input to the unit 215 (S13). As a result, the main control unit 215 activates the program execution environment shown in FIG. 7, that is, the application program execution management unit 214 shown in FIG. 6 (S14). Then, the application program execution management unit 214 reads the JAR file, refers to it, and sets an execution environment suitable for the application program (S15). When an appropriate environment is set for each application program in this way, the application program execution management unit 214 reads the JAR file and activates the application program (S16).

  When the application program of the music player is activated in this way, first, a list of name data (hereinafter referred to as “song name list”) which is specific data of all music data stored in the platform storage area of the RAM 202 is acquired. (S17). Specifically, as shown in FIG. 9, first, in the program execution environment, the activated application program sends a song name list acquisition request to the application program execution management unit 214. Receiving this, the application program execution management unit 214 sends an acquisition request for the song name list to the main control unit 215 of the telephone platform. Receiving this, the main control unit 215 sends the song name list of the music data stored in the RAM 202 to the application program execution management unit 214, and this song name list is passed to the application program.

Thereafter, when a song name desired by the user is selected from the song name list displayed on the liquid crystal display 27, music data corresponding to the song name is reproduced (S18). Specifically, as shown in FIG. 9, when a specific song name is selected by the user, a reproduction request for music data corresponding to the song name is sent from the application program to the application program execution management unit 214. In response to this, the application program execution management unit 214 reads name data corresponding to the song name from the application storage area of the RAM 202, and sends a music data reproduction request corresponding to the name data to the main control unit 215 of the telephone platform. put out. As a result, the main control unit 215 reads the music data according to the request from the platform storage area of the RAM 202 and reproduces it.
In this way, by executing the application program of the music player, the user can reproduce and listen to the music data stored in the platform storage area of the RAM 202.

  Next, the processing operation when the application program is resumed after the user closes the clamshell and the application program is temporarily stopped, which is a characteristic part of the present invention, will be described. Here, the case where the clamshell is closed and paused will be described as an example. However, the same applies to the case where the incoming call is received or the user does not perform any operation for a certain period of time.

FIG. 1 is a flowchart showing the flow of processing when the application program is restarted in the first embodiment.
When the user closes the clamshell while the application program execution management unit 214 is executing the application program, the shell open / close detection unit 217 shown in FIG. 6 detects this and detects that the clamshell is closed. A signal is input to the main control unit 215. As a result, the main control unit 215 recognizes that the clamshell is closed, and outputs an event indicating that the shell is closed to the application program execution management unit 214. Then, the application program execution management unit 214 executes processing for temporarily stopping the application program being executed. The application program paused in this way can be resumed by the user performing a predetermined resumption operation.

  Specifically, when the user performs a predetermined resumption operation (S1), the operation content is sent from the operation unit 213 to the main control unit 215, and the main control unit 215 sends a resumption instruction to the application program execution management unit 214. send. Here, while the application program is paused, the user can delete or change the music data stored in the platform storage area of the RAM 202, or add new music data to the storage area. When the storage contents of the storage area are updated, the correspondence between the music data stored in the platform storage area and the song name list stored in the application storage area does not match, and the restarted application program is properly May not work.

  Therefore, in the first embodiment, when the storage contents of the platform storage area are updated during the suspension of the application program, the main control unit 215 sends an update notification indicating that the music data has been updated to the application program. The data is sent to the execution management unit 214 (S2). Receiving this, the application program execution management unit 214 performs the song name list acquisition process again in the same manner as the process of S17 described above (S3). Thereafter, the application program execution management unit 214 restarts the application program (S4). Thus, when the music data reproduction process (S18) is performed by the resumed application program, the correspondence between the music data stored in the platform storage area and the song name list stored in the application storage area The relationship is in agreement.

  On the other hand, when the storage contents of the platform storage area are not updated during the suspension of the application program, the main control unit 215 does not send the update notification to the application program execution management unit 214. In this case, since the correspondence relationship between the music data stored in the platform storage area and the song name list stored in the application storage area is in agreement, the application program execution management unit 214 obtains the song name list. The application program is resumed as it is (S4).

  As described above, according to the first embodiment, the correspondence relationship between the music data stored in the platform storage area and the song name list stored in the application storage area can be always matched. When the program tries to reproduce the music data in the platform storage area, the music data is deleted and cannot be reproduced. Further, for example, even when new music data is added during the pause, the music data can be reproduced by the resumed application program. Moreover, according to the first embodiment, the application program execution management unit 214 determines whether the storage contents of the platform storage area have been updated during the suspension of the application program based on the presence or absence of an update notification sent from the main control unit 215. Can be recognized. Therefore, the operation delay of the application program can be suppressed as compared with the case where the process of acquiring the song name list is performed every time the program is restarted.

  In the first embodiment, the notification sent from the main control unit 215 to the application program execution management unit 214 simply indicates that it has been updated. Therefore, the application program execution management unit 214 cannot recognize the contents of the data update. In other words, the application program execution management unit 214 cannot recognize whether the music data has been deleted, changed, or added, and recognizes which music data has been updated. I can't do that either. Therefore, in the first embodiment, when an update notification is received, a process for acquiring a song name list for all music data is performed in the same manner as the process for acquiring a song name list (S17) when the application program is activated. When the number of music data in the platform storage area is small, the data volume of the song name list is relatively small. Therefore, even if processing such as obtaining a song name list for all music data is performed, the operation delay is delayed. Has little effect. However, when the number of music data in the platform storage area is large, the data amount of the song name list becomes large, which may cause a delay in operation.

  Therefore, for example, when new music data is added during a pause, address data indicating the storage location of the music data (update data information) may be included in the update notification. In this case, the application program execution management unit 214 issues an acquisition request to the main control unit 215 only for the name data of the music data related to the address data, and acquires only the name data. As a result, even when the number of music data is large, there is no possibility of causing an operation delay. Such an operation is generally effective when the amount of data acquired from the main control unit 215 and stored in the application storage area is large.

In the first embodiment, the case where the music data stored in the platform storage area of the RAM 202 is used has been described. However, the case where the music data stored in the memory card 32 as the first storage unit is used is described. The same is true.
In the first embodiment, the music data list of music data stored in the platform storage area of the RAM 202 is stored in the application storage area, and the music data in the platform storage area specified by the music name list is reproduced. Although the case has been described, the same applies to the case where the music data stored in the platform storage area is copied and stored in the application storage area and the copy data is reproduced.

[Embodiment 2]
Next, another embodiment of the present invention (hereinafter, this embodiment is referred to as “Embodiment 2”) will be described.
In the second embodiment, a song name list of music data stored in the memory card 32 as the first storage means is stored in the application storage area, and the music data in the memory card 32 specified by this song name list is stored. A case of reproduction will be described. In the following description, the description of the same parts as those in the first embodiment will be omitted.

FIG. 10 is a flowchart showing the flow of processing when the application program is restarted in the second embodiment.
As in the first embodiment, the application program execution management unit 214 that has executed the application program temporarily stops the execution of the clamshell when the user closes the clamshell during execution of the application program. When the user performs a predetermined resumption operation (S1), the main control unit 215 sends a resumption instruction to the application program execution management unit 214. Here, if the user removes the memory card 32 from the main body of the mobile phone 20 while the application program is paused, and the memory card 32 is not attached at the time of the restart, even if the restarted application program tries to play music, There is no memory card 32 that stores the music data. Therefore, the resumed application program may not operate properly.

  Therefore, in the second embodiment, after a predetermined resumption operation is performed by the user (S1), the main control unit 215 detects from the detection sensor that detects the attachment / detachment state of the memory card 32 provided in the memory card attachment unit 218. A detection result is acquired and the attachment / detachment state of the memory card 32 is confirmed (S21). If the memory card 32 has been removed, the main control unit 215 sends a card no-notification indicating that the memory card 32 has been removed to the application program execution management unit 214 (S22). Receiving this, the application program execution management unit 214 performs a process of displaying a warning screen indicating that the memory card 32 is removed on the liquid crystal display 27 of the output unit 216 via the main control unit 215 (S23). In this case, the application program is not resumed until the memory card 32 is inserted.

When the user removes the memory card 32 from the main body of the mobile phone 20 and inserts a new memory card 32 while the application program is paused, the music data stored in the new memory card 32 and the application storage area The correspondence relationship with the song name list stored in is not consistent. That is, there is no song name list corresponding to the music data stored in the new memory card 32 in the application storage area. Therefore, the music data stored in the new memory card 32 cannot be reproduced by the resumed application program, and the resumed application program may not operate properly.
Therefore, in the second embodiment, when the memory card 32 is replaced while the application program is paused, the main control unit 215 notifies the card replacement notification indicating that a new memory card has been installed. The data is sent to the unit 214 (S24). Receiving this, the application program execution management unit 214 performs the song name list acquisition process again as in the case where the music data is updated in the first embodiment (S3). Thereafter, the application program execution management unit 214 restarts the application program (S4). Thereby, when the music data reproduction process (S18) described above is performed by the resumed application program, the correspondence between the music data stored in the memory card 32 and the song name list stored in the application storage area Are matched.

  On the other hand, if the memory card 32 is not replaced while the application program is paused, the main control unit 215 does not send the card replacement notification to the application program execution management unit 214. In this case, since the correspondence between the music data stored in the attached memory card 32 and the song name list stored in the application storage area is in agreement, the application program execution management unit 214 uses the song name list. Is not performed, and the application program is resumed as it is (S4).

  As described above, according to the second embodiment, an operation such as trying to reproduce music data stored in the memory card 32 that has been removed and does not exist is not performed, so that the resumed application program can operate appropriately. In addition, in this embodiment, the application program execution management unit 214 determines whether the memory card 32 has been removed or a new memory card 32 has been installed depending on whether there is a card-notification notification or a card replacement notification sent from the main control unit 215. Can be recognized. Accordingly, it is possible to suppress the delay of the operation of the application program, as compared with the case where it is checked every time whether the memory card is inserted each time the process is restarted or the process of reacquiring the song name list is performed every time.

In the first and second embodiments described above, a mobile phone that can execute an application program developed by object-oriented programming that does not depend on a platform using a program language such as JAVA has been described. However, the present invention is not limited to this. .
Further, the present invention can be applied not only to mobile phones, but also to portable PDAs in addition to phones such as PHS and automobile phones, and similar effects can be obtained.
