Description

  The present invention relates to a portable terminal, a server, a stored data management method, and a communication system, and more particularly to a portable terminal, a server, a stored data management method, and a communication system capable of transferring stored data.

  In recent years, an increasing number of scenes are used to transfer a large amount of data such as images, videos, music, etc. in a server (for example, a PC (Personal Computer) server) to a portable terminal and carry it around regardless of location or time. Yes.

  On the other hand, as an example of this type of invention, the client-side mobile terminal can virtually store the shared data of the server-side mobile terminal in a virtual folder so that it is virtually stored in the client-side mobile terminal. A virtual data sharing system to be handled is disclosed. The listing of the shared data to the virtual folder is common with the index data of the present invention (see, for example, Patent Document 1).

  As another example of this type of invention, data transfer is disclosed in which index information is generated and data is transferred between portable terminals and between server computers (see, for example, Patent Document 2).

  As another example of this type of invention, the portable terminal has a memory for temporarily storing still image information as digital data, and the server has a storage unit for storing the digital data acquired by the portable terminal. Thus, an information processing system is disclosed in which the amount of still image data handled by the mobile terminal does not depend on the memory capacity (see, for example, Patent Document 3). The present invention is common to the present invention in that data is transferred between the portable terminal and the server.

  As another example of this type of invention, an invention is disclosed in which only data designated by a filter in a server is synchronized with a portable terminal (see, for example, Patent Document 4). Further, an invention is disclosed in which, when data in a server and accompanying information are updated, update data that meets a specific condition set by a user is distributed to a mobile terminal (see, for example, Patent Document 5). In addition, an invention is disclosed in which an image captured by a mobile terminal is immediately stored in a server (see, for example, Patent Document 6).

JP-A-2005-284407 JP 2005-173667 A Japanese Patent Laid-Open No. 10-336238 JP 2005-038030 A Japanese Patent Laid-Open No. 2005-191912 Japanese Patent Laid-Open No. 2003-078905

  A portable terminal related to the present invention, that is, a portable terminal capable of data synchronization with a server has the following problems.

  The first problem is that, as a premise, since the capacity of the storage device of the mobile terminal is smaller than that of the PC server, all data such as images, videos and music stored in the PC server are transferred to the mobile terminal. This is difficult, and only a part of the data stored in the PC server is stored in the portable terminal.

  Therefore, the data that the user carries in advance with the portable terminal is selected and downloaded from the PC server within the capacity of the storage device of the portable terminal, or the data is deleted from the portable terminal depending on the remaining capacity of the storage device It is necessary to carry out the replacement work, and it takes time and effort.

  The second problem is the result of repeated data transfer between the mobile terminal and the PC server. As a result, "Which data exists in the PC server now exists in the mobile terminal", "Newly created in the mobile terminal The user cannot know immediately which one of the data is stored in the PC server unless he / she takes time and effort using several procedures and methods.

  On the other hand, in the present invention, status information such as a holding state or a discarding state indicating whether the data is held by both the portable terminal and the server or only by the server is managed by the index data. On the other hand, the invention disclosed in Patent Document 1 has no description of managing such state information, and therefore, the invention disclosed in Patent Document 1 is completely different from the object of the present invention, and the configuration for achieving the object is completely different. It is a different invention.

  Further, the index information of the invention disclosed in Patent Document 2 does not include state information such as the above-mentioned holding state or discarding state. The invention disclosed in Patent Document 3 also has no description of the configuration corresponding to the index data or the index information. Therefore, the invention disclosed in Patent Document 3 is another invention whose purpose and structure are completely different from those of the present invention. Further, the invention disclosed in Patent Document 4 has a drawback that the user must specify a filter in advance.

  Further, the invention disclosed in Patent Document 5 has no description about discarding data distributed to the mobile terminal. In addition, the invention disclosed in Patent Document 6 does not describe data acquisition from a server. Therefore, since the inventions disclosed in Patent Documents 5 and 6 are not inventions relating to data destruction or data acquisition, there is a drawback that the user has to take care of himself and select discard data or acquisition data. . Therefore, no means for solving the problems of the present invention is disclosed in the inventions disclosed in Patent Documents 1-6.

  Therefore, an object of the present invention is to allow the user to use all data in the server from the portable terminal without the user performing data exchange between the portable terminal and the server in advance, and from the portable terminal to the portable terminal and the server. It is an object of the present invention to provide a portable terminal, a server, a stored data management method, and a communication system capable of grasping at a glance the holding state and the discarding state of all of the data.

  In order to solve the above problems, a portable terminal according to the present invention includes a storage device, index data for displaying data stored in the storage device and items corresponding to the data as a pair, and the data and the index data on a server. When the data to be temporarily discarded from the storage device and the communication device to be transmitted, the item corresponding to the data is not deleted from the index data, the status information in the temporary discard state is added to the index data, and the changed data When index data is transmitted to the server via the communication unit and new data is added to the storage device, the data and items corresponding to the data are added to the index data, and the added new data and after the change A data updating unit for transmitting the index data to the server via the communication unit; Characterized in that it contains.

  The server according to the present invention receives the index data and data from a mobile terminal, and stores at least the received data in a storage device in the server.

  Further, the stored data management method according to the present invention includes a storage device, index data for displaying data stored in the storage device and an item corresponding to the data as a pair, and communication for transmitting the data and the index data to a server. A stored data management method in a portable terminal including a data update unit and a data update unit, wherein the data update unit deletes an item corresponding to the data from the index data when the data is temporarily discarded from the storage device. Without adding the status information in the temporary discard state to the index data, transmitting the changed index data to the server via the communication unit, and adding the new data to the storage device and the data Items corresponding to data are added to the index data, and new data and changes added Characterized by the index data transmitted to the server via the communication unit.

  The communication system according to the present invention includes a portable terminal and a server, and a communication network connected between the portable terminal and the server.

  Further, the program according to the present invention includes a storage device, index data that displays data stored in the storage device and an item corresponding to the data as a pair, a communication unit that transmits the data and the index data to a server, A stored data management method program in a portable terminal including a data update unit, and when the data update unit temporarily discards data from the storage device, the item corresponding to the data is not deleted from the index data In the case of adding the status information in the temporary discard state to the index data, transmitting the changed index data to the server via the communication unit, and adding new data to the storage device, the data and the data Is added to the index data, and the added new data and The index data Sarago via the communication unit transmits to said server, characterized in that it is a program for executing the process.

  According to the present invention, all data in the server can be used from the mobile terminal without the user performing data exchange between the mobile terminal and the server in advance, and the user can access the mobile terminal and the server from the mobile terminal. It is possible to grasp at a glance the holding state and the discarding state of all data.

  First, the operating principle of the present invention will be described prior to describing the embodiment of the present invention. FIG. 1 is a block diagram showing an example of the operating principle of a mobile terminal according to the present invention. Referring to the figure, a portable terminal 1 according to the present invention includes a storage device 11, index data 13 that displays data 12 stored in the storage device 11 and items corresponding to the data as a pair, data 12 and an index. And a communication unit 14 that transmits the data 13 to the server.

  Furthermore, when the mobile terminal 1 according to the present invention temporarily discards the data 12 from the storage device 11, the item corresponding to the data 12 is not deleted from the index data 13, and the status information in the temporary discard state is transferred to the index data 13. The index data 13 after the change is transmitted to the server via the communication unit 14, and when adding new data to the storage device 11, the data and items corresponding to the data are added to the index data 13, A data update unit 15 that transmits the added new data and the changed index data 13 to the server via the communication unit 14 is included.

  Next, an example of the operation of the mobile terminal 1 will be described. 2 and 3 are schematic diagrams illustrating an example of the operation of the mobile terminal 1. First, the operation shown in FIG. 2 will be described. FIG. 2A shows a state in which a part of the data stored in the mobile terminal 1 is temporarily discarded. In this state, a part of the data 101 is deleted from the storage device 11 of the mobile terminal 1.

  “Temporary discard” refers to data that is once deleted from the storage device 11 but can be rewritten to the storage device 11. In such a temporary discard, the item of the index data 102 in the portable terminal 1 Items relating to the data 101 are not deleted. Instead, the temporary discard status information is added to the index data 102.

  On the other hand, the index data 103 on the server side is always synchronized with the index data 102 on the mobile terminal 1 side, and the contents are always matched. Therefore, when the data 101 is temporarily discarded from the mobile terminal 1, the data update unit 15 of the mobile terminal 1 transmits the updated index data 102 to the server.

  On the server side, the index data 103 is synchronized with the index data 102. That is, the index data 103 on the server side is updated with the index data 102 on the mobile terminal 1 side, and the contents of the index data 103 and the contents of the index data 102 match. In the case of temporary destruction, the server-side data 104 corresponding to the temporary destruction data 101 is not deleted from the storage device on the server side.

  That is, referring to the index data 102 on the mobile terminal 1 side, it can be seen that the data 101 is currently in a temporarily discarded state, and referring to the server side index data 103, the data 101 on the mobile terminal 1 side corresponding to the data 104 is obtained. It can be seen that it is currently temporarily destroyed.

  Next, an operation of rewriting the temporarily discarded data 101 in the storage device 11 of the mobile terminal 1 will be described. FIG. 2B shows a state in which data temporarily discarded by the mobile terminal 1 is rewritten from the server.

  It can be seen from the index data 102 on the mobile terminal 1 side that the data 101 is in a temporarily discarded state. Therefore, when the data 101 is accessed in the mobile terminal 1, the data update unit 15 refers to the index data 102 and acquires the data 104 corresponding to the data 101 from the storage device on the server side. Then, the data updating unit 15 changes the state information in the data 101 to the holding state, and transmits the changed index data 102 to the server.

  On the server side, the index data 103 is synchronized with the index data 102. That is, the index data 103 on the server side is updated with the index data 102 on the mobile terminal 1 side, and the contents of the index data 103 and the contents of the index data 102 match.

  That is, referring to the index data 102 on the mobile terminal 1 side and the index data 103 on the server side, the data 101 on the mobile terminal 1 side is in a temporarily discarded state, and the corresponding data 104 of the data 101 is on the server side. It can be seen that it exists in the storage device. Therefore, when the data 101 is accessed on the portable terminal 1 side, the data can be immediately acquired from the server side.

  Next, the operation shown in FIG. 3 will be described. FIG. 3A shows a state in which new data 111 is added to the mobile terminal 1. In this case, the data update unit 15 adds the new data 111 and items corresponding to the data to the index data to obtain the index data 112. On the other hand, in this state, the index data 113 on the server side shows the state before the addition of the new data 111, and therefore the contents are different from the index data 112.

  Therefore, the data update unit 15 of the mobile terminal 1 transmits the updated index data 112 and the added new data 111 to the server. FIG. 3B shows a state in which the updated index data 112 and the added new data 111 are transmitted from the mobile terminal 1 to the server side.

  On the server side, the index data 113 and the updated index data 112 are synchronized. That is, the index data 113 on the server side is updated with the index data 112 on the mobile terminal 1 side, and the contents of the index data 113 and the contents of the index data 112 match.

  Thus, by referring to the index data 112 on the mobile terminal 1 side and the index data 113 on the server side, it is possible to grasp at a glance which data currently exists in the mobile terminal 1 and which data exists in the server. Is possible.

  Hereinafter, embodiments of the present invention will be described. FIG. 4 is a configuration diagram of an example of a communication system according to the present invention. Referring to the figure, an example of a communication system according to the present invention includes a mobile terminal 10, a PC server 50, and a communication network 40. The mobile terminal 10 and the PC server 50 are connected via the communication network 40. Connected.

  The mobile terminal 10 includes an information processing device 20 and a storage device 30. The information processing apparatus 20 includes a timer notification unit 201, a data update unit 202, a communication unit 203, a data selection / update UI (User Interface) 204, and a program storage unit 205. In the information processing apparatus 20, software such as an operating system and applications is operating.

  For each data, the timer notification unit 201 notifies the data update unit 202 when the specified time has elapsed since the data was used. The data update unit 202 updates data in the storage device 30 based on input information from other modules. In addition, the data update unit 202 transmits the updated data from the communication unit 203 to the PC server 50 via the communication network 40. In addition, when the data update unit 202 receives a notification that the specified time has elapsed from the timer notification unit 201, the data update unit 202 temporarily discards the corresponding data.

  The communication unit 203 communicates with a communication unit described later in the PC server 50 via the communication network 40. The data selection / update UI 204 is an interface for the user to select or update data. The program storage unit 205 stores a program for a stored data management method to be described later. The data update unit 202 reads this program from the program storage unit 205 and controls each of the parts 201, 203, 204 and 30 according to the program.

  The storage device 30 is configured as a non-volatile storage device as an example, and includes index data 301 and individual data 302. The index data 301 can also be stored in a storage device that is separate from the storage device 30.

  The index data 301 includes a list of individual data 302 including those temporarily discarded. The index data 301 also describes information on the temporary discard state and the holding state. Further, the index data 301 is synchronized with index data to be described later in the PC server 50, and both have the same contents. The individual data 302 is not necessarily the same as the individual data in the PC server 50 because some data is temporarily discarded.

  The communication network 40 is a wired or wireless communication network. The PC server 50 includes an information processing device 60 and a storage device 70. The information processing apparatus 60 includes a communication unit 601, a data update unit 602, and a data update UI 603.

  The communication unit 601 communicates with the communication unit 203 in the mobile terminal 10 via the communication network 40. The data update unit 602 updates data in the storage device 70 based on input information from other modules. Further, the data update unit 602 transmits the updated data from the communication unit 601 to the mobile terminal 10 via the communication network 40. The data update UI 603 is an interface for the user to update data.

  The storage device 70 is configured as a non-volatile storage device as an example, and includes index data 701 and individual data 702. The index data 701 can also be stored in a storage device that is separate from the storage device 70.

  The index data 701 describes a list of individual data 702. Unlike the individual data 302 in the mobile terminal 10, the individual data 702 does not have a temporary discard state.

  Instead of the timer notification unit 201 in the mobile terminal 10, it is possible to provide a module that senses the occurrence of another discard condition and outputs a discard request to the data update unit 202. As an example, a module that outputs a discard request to the data update unit 202 when the remaining capacity of the storage device 30 in the mobile terminal 10 falls below a predetermined percentage may be provided.

  Next, an example of index data will be described. FIG. 5 is a configuration diagram of an example of index data in the communication system according to the present invention. FIG. 2A shows an example of index data held by the mobile terminal 10, and FIG. 2B shows an example of index data held by the PC server 50. FIG. The figure shows, as an example, the contents of index data of the mobile terminal 10 and the PC server 50 when the data A is temporarily discarded from the storage device 30 of the mobile terminal 10.

  First, an example of index data held by the mobile terminal 10 will be described with reference to FIG. The mobile terminal 10 side index data includes an item field, a status field of mobile terminal data, and a data field. Further, the status column of the mobile terminal data includes a temporary discard column and a holding column.

  “Item” is, for example, a serial number starting from 1, and corresponds to a “data” name. “The state of the mobile terminal data” indicates the current state of the data in the mobile terminal 10. When a check mark (“O” as an example) is added to “Temporary Discard”, this indicates that the data of the item is currently in a temporary discard state and has been deleted from the storage device 30. On the other hand, when a check mark (“O” as an example) is added to “Hold”, it indicates that the data of the item is held in the storage device 30. “Data” indicates the name of the data (for example, “A”, “B”, “C”, “D”, etc.).

  Currently, since data A is temporarily discarded from the storage device 30 of the mobile terminal 10, the data A is actually deleted from the storage device 30 of the mobile terminal 10. Therefore, the row of “item 1” to which the data A corresponds should be deleted, but is not deleted in the present invention. This means that the user can select “item 1” at a later date, and when the user wants to use the discarded data, the user can select the data from the index data and download it from the PC server 50. Because. Therefore, a check mark (“O”) is added to the temporary discard column in the status column of the mobile terminal data of item 1 corresponding to data A. On the other hand, since the other data B, C, D, etc. are not temporarily discarded, a check mark (“O”) is added to the holding column.

  Next, an example of index data held by the PC server 50 will be described with reference to FIG. As shown in FIG. 5B, the contents of the index data on the PC server 50 side are the same as the contents of the index data on the mobile terminal 10 side. This is because each time the content of the storage device 30 of the mobile terminal 10 is updated, the index data is also updated in the mobile terminal 10, the updated index data is transmitted to the PC server 50, and the index data on the PC server 50 side. This is because the mobile terminal 10 side index data is synchronized.

  On the other hand, even if the data A is deleted from the storage device 30 of the mobile terminal 10, if it is temporarily discarded, the data A is not deleted from the storage device 70 of the PC server 50. In order to clearly display the “temporary discard status”, for example, the display color of the item column or the entire row of data in the “temporary discard status” in the index data is changed to a different color from the other parts. Is possible.

  Therefore, referring to the index data shown in FIGS. 4A and 4B, the data A is temporarily discarded from the storage device 30 of the mobile terminal 10 both from the mobile terminal 10 side and from the PC server 50 side. I understand that. Thereby, it becomes possible to grasp what data is currently stored in the mobile terminal 10 and the PC server 50 without taking time and effort.

  Next, an example of the operation of the mobile terminal 10 will be described. First, an operation for temporarily discarding data from the storage device 30 of the mobile terminal 10 will be described. FIG. 6 is a flowchart showing an example of data temporary discard processing in the mobile terminal according to the present invention. This process is executed by the data updating unit 202 in the information processing apparatus 20 controlling the parts 201, 203 and 204.

  First, the data update unit 202 reads predetermined data from the storage device 30 based on an instruction from the user via the data selection / update UI 204 (step S1). When the reading is completed (in the case of “Yes” in step S2), the data update unit 202 activates the timer notification unit 201 (step S3).

  When the specified time set in the timer notification unit 201 has elapsed (in the case of “Yes” in step S4), the timer notification unit 201 notifies the data update unit 202 of a request for temporary destruction of predetermined data (step S5). Upon receiving this notification, the data updating unit 202 deletes predetermined data from the storage device 30 (step S6).

  Then, the data update unit 202 does not delete the temporarily discarded data item from the data list of the index data 301, and changes the “mobile terminal data state” from “held” to “temporarily discarded” (step S7). Next, the data update unit 202 transmits the updated index data 301 to the PC server 50 (step S8). This is the end of this process.

  As described above, the predetermined data is deleted from the storage device 30 of the mobile terminal 10, the deletion is “temporarily discarded”, is displayed in the index data 301, and the updated index data 301 is transmitted to the PC server 50. Is done.

  In step S2, if the reading is not completed (“No” in step S2), the data updating unit 202 waits until the reading is completed. In step S4, when the designated time does not elapse (in the case of “No” in step S4), the timer notification unit 201 waits until the designated time elapses.

  Thereafter, the index data 701 and the index data 301 in the portable terminal 10 are synchronized in the PC server 50, and the contents of the index data 701 are changed to match the contents of the index data 301. In this case, since the notification of deletion of the predetermined data is not made from the mobile terminal 10, the predetermined data in the storage device 70 of the PC server 50 is not deleted.

  Next, processing such as new creation, update, and acquisition of data in the mobile terminal 10 will be described. FIG. 7 is a flowchart showing an example of processing such as new creation, update, and acquisition of data in the mobile terminal according to the present invention.

  First, when data in the mobile terminal 10 is accessed from the user via the data selection / update UI 204, the data update unit 202 determines whether the data accessed by the user is newly created data that does not exist in the index data 301. It is checked whether the data is in a certain holding state or is temporarily discarded (step S11).

  When the data accessed by the user is newly created data that does not exist in the index data 301, the data update unit 202 adds an item for the newly created data to the index data 301, adds a check mark to the “hold” column, The name of the newly created data (for example, “E”) is added to the “data” column (step S12).

  Next, the data updating unit 202 transmits the updated index data 301 to the PC server 50 (step S13). Next, the data update unit 202 transmits newly created data to the PC server 50 (step S14). When the newly created data is received by the PC server 50, a reception completion notification is transmitted from the PC server 50 to the portable terminal 10 (step S14). This is the end of this process.

  The reason why the reception completion notification needs to be transmitted is that, in the present invention, only data that has been saved in the PC server 50 is temporarily discarded. On the PC server 50 side, the newly created data received is stored in the storage device 70, and the index data 701 and the received index data 301 are synchronized.

  Returning to step S11, when the data accessed by the user is in the hold state and the operation performed on the accessed data is deletion of data (step S15), the data update unit 202 stores the data in the index data 301. The entire row in which the corresponding data item exists is deleted (step S12), and the updated index data 301 is transmitted to the PC server 50 (step S13). Next, the data updating unit 202 transmits an instruction to delete the corresponding data to the PC server 50 (step S14).

  The PC server 50 that has received this data deletion command transmits a reception completion notification to the portable terminal 10 (step S14). This is the end of this process. On the PC server 50 side, the index data 701 and the received index data 301 are synchronized, and the corresponding data is deleted from the storage device 70.

  Returning to step S11, when the data accessed by the user is in the hold state and the operation performed on the accessed data is a data name change (step S15), the data updating unit 202 stores the index data 301 in the index data 301. The name of the corresponding data is changed (step S12), and the updated index data 301 is transmitted to the PC server 50 (step S13).

  Next, the data update unit 202 transmits the data whose name has been changed to the PC server 50 (step S14). The PC server 50 that has received the data whose name has been changed transmits a reception completion notification to the portable terminal 10 (step S14). This is the end of this process. On the PC server 50 side, the index data 701 and the received index data 301 are synchronized, and the name of the corresponding data in the storage device 70 is changed.

  Returning to step S11, when the data accessed by the user is in the hold state and the operation performed on the accessed data is "update and save data" (step S15), the data update unit 202 The corresponding data is updated and stored in the storage device 30. Then, the data update unit 202 transmits the updated data to the PC server 50 (step S14). The PC server 50 that has received the updated data transmits a reception completion notification to the mobile terminal 10 (step S14).

  This is the end of this process. On the PC server 50 side, the corresponding data in the storage device 70 is overwritten with the data transmitted from the mobile terminal 10. In this case, the index data 301 is not updated and is not transmitted to the PC server 50.

  Returning to step S11, when the data accessed by the user is in a holding state and the operation performed on the accessed data is “viewing only” (step S15), updating of the individual data is also performed on the index data. Since no update is performed, nothing is transmitted from the mobile terminal 10 to the PC server 50. This is the end of this process.

  Returning to step S11, if the data accessed by the user is in a temporarily discarded state, the data update unit 202 acquires the corresponding data from the PC server 50 (step S16), and the corresponding data item in the index data 301 in the mobile terminal 10 Is changed from “temporary discard” to “hold” (step S17), and the updated index data 301 is transmitted to the PC server 50 (step S18). This is the end of this process. On the PC server 50 side, the index data 701 and the received index data 301 are synchronized.

  Finally, a stored data management method program in the mobile terminal will be described. As described above, in the description of an example of the communication system according to the present invention (see FIG. 4), it has been described that the information processing apparatus 20 in the mobile terminal 10 includes the program storage unit 205. The program storage unit 205 stores a program for a stored data management method in the portable terminal shown in the flowcharts of FIGS. 6 and 7.

  The data update unit 202 in the information processing apparatus 20 reads the program from the program storage unit 205 and controls the timer notification unit 201, the communication unit 203, the data selection / update UI 204, and the storage device 30 according to the program. Since the contents of the control have already been described, the description thereof is omitted here.

  In the above-described embodiment, the PC server is described as an example of the server. However, the present invention is not limited to this, and can be configured by other servers (for example, a communication device including a data storage device). .

  As described above, according to the embodiment of the present invention, the user can use all data of the PC server from the mobile terminal without exchanging data between the mobile terminal and the PC server in advance. The reason is that data synchronized between the mobile terminal and the PC server is temporarily discarded from the mobile terminal according to specific conditions, and the temporary discard is not reflected in the data in the PC server. This is because an item of the data is not deleted from the index data that is a list, and the user selects the data from the index data and obtains it from the server when the user wants to use it on the mobile terminal.
