JP 2001-274841 A

  In recent years, a system has been considered in which a plurality of communication terminals have the same mail account using cloud technology, and the communication terminals transmit and receive electronic mail related to the same mail account. In this system, e-mail data (including header information and bibliographic information, as well as e-mail text and attached files) is stored on the cloud server. (Title, destination, etc.) and bibliographic information (various statuses for e-mail data, etc.) only. And when a user browses each electronic mail data, a communication terminal can display a mail text and an attached file by acquiring a mail text and an attached file from a cloud server.

  In a mail system using such cloud technology, a user can operate e-mail data held in a communication terminal without connecting to a mail server. For example, by operating a communication terminal, a user creates a new folder in a mailbox held in the communication terminal, deletes e-mail data from the mailbox, or renames a folder or the like be able to. In this case, since only the e-mail data and folder held in the communication terminal are changed, the server and the communication terminal are not changed unless the same change is made to the e-mail data and folder held in the mail server. Inconsistency occurs in the stored e-mail data and folders.

  In order to eliminate the inconsistency described above, it is conceivable that information changed from the communication terminal to the server is transmitted to the server as synchronization information, and the server performs synchronization processing using the synchronization information. If it transmits to a server every time, since the frequency | count of communication will increase, the communication load between a communication terminal and a server will be applied.

  Accordingly, in order to solve the above-described problems, the present invention has an object to provide a communication terminal device and a synchronization information output method that reduce the communication load during synchronization processing of information related to mail between the communication terminal and the server. And

  The communication terminal device according to the present invention includes a mail server that distinguishes and holds mail data of the communication terminal device for each folder, and a communication terminal device that is communicably connectable, and mail data that distinguishes and holds mail data for each folder Holding means, management processing means for performing management processing of mail data and folders, identification information of mail data or folders to be managed, information indicating management processing contents, status information after management processing or user information Management processing information generation means for generating management processing information including the changed status that is the operation content, management processing information holding means for holding management processing information, and management processing information held by the management processing information holding means Based on the status after the change of multiple management process information that has the same management process identification information or management process content Management processing information aggregating means for performing aggregation processing, and e-mail synchronization information that is information for synchronizing mail data held by the mail server and mail data held by the communication terminal device based on the result of the aggregation processing Synchronizing means for outputting to a server.

  In addition, the synchronization information output method according to the present invention is connectable to a mail server that distinguishes and holds mail data of a communication terminal device for each folder, and is in a communication terminal device that distinguishes and holds mail data for each folder. There is an information output method for synchronization, a management processing step for performing management processing of mail data and folders, identification information of the mail data or folder to be managed, information indicating management processing contents, and a state after the management processing Management processing information generation step for generating management processing information including information or the changed status that is the operation content of the user, management processing information holding step for holding management processing information, and management processing held in the management processing information holding step Among the information, changes to multiple management process information that have the same management process identification information or management process content Management processing information aggregation processing for performing aggregation processing to be aggregated based on the post status, and mail data held by the mail server and mail data held by the communication terminal device are synchronized based on the result of the aggregation processing A synchronization step of outputting information for synchronization, which is information for the purpose, to the mail server.

  According to such a communication terminal device and the synchronization information output method, a plurality of management processes having the same identification information or management process contents among the management process information held by the management process information holding unit. Since information is aggregated based on the status after the change and the synchronization information based on the aggregated result is output to the mail server, it is compared with the case where the synchronization information is notified to the mail server each time management processing is performed. Thus, the communication load between the communication terminal device and the mail server can be reduced.

  In the communication terminal device according to the present invention, the management processing information associates the status information before the management processing with the changed status, and the management processing information aggregation means uses the status information before the management processing and the changed status. To perform aggregation processing. In this case, since the communication terminal device also has information before the change, it is possible to determine whether the information is changed by comparing the information before the change with the latest state, and a plurality of management processes are performed. As a result, the processing that does not change from the initial state is not notified to the mail server, and the communication load at the time of synchronization processing of information about mail between the communication terminal device and the mail server can be reduced.

  In the communication terminal apparatus according to the present invention, the aggregation processing is performed by changing a plurality of management processing information having the same identification information or management processing content among the management processing information held by the management processing information holding means. This is a process of referring to the post status and specifying the state after the latest management process for the management process target. In this case, the communication terminal device refers to the status information after the management processing of the plurality of management processing information and identifies the status after the latest management processing for the target of the management processing. Compared with the case of notifying the mail server one by one, the communication load between the communication terminal device and the mail server can be reduced.

  In the communication terminal device according to the present invention, the management processing information aggregating means manages the management information when the status information before the management processing of the oldest management processing information among the management processing information to be aggregated is the same as the aggregated information. The synchronization unit determines that the processing target has not been changed, and the synchronization unit excludes the aggregation result determined to have not been changed by the management processing information aggregation unit from the synchronization information. In this case, if the result of aggregation is the same as the status information before management processing in the oldest management processing information among the management processing information to be aggregated, the communication terminal apparatus determines that the information has not been changed, Since the aggregation result is not output to the mail server as synchronization information, the management process is performed a plurality of times, and as a result, the processing result that does not change from the original state is not notified to the mail server. It is possible to reduce the communication load during synchronization processing between the two.

  In the communication terminal device according to the present invention, the synchronization unit aggregates the result of aggregation with the identification information of the management processing target or the information of the management processing content with the identification information of the management processing target or other information of the management processing content. Output synchronization information. In this case, since the synchronization information is collectively output based on the identification information of the management processing target or the management processing content, the number of communication is reduced as compared with the case of outputting to the mail server every time the management processing occurs. Thus, the communication load can be reduced.

  According to the present invention, it is possible to reduce the communication load between the communication terminal device and the mail server as compared with the case where the synchronization information is notified to the mail server every time the management process is performed.

  Here, FIG. 5 shows the data structure of the management processing information. As shown in FIG. 5, the management processing information indicates a “mail ID or folder ID” that functions as management processing target mail or folder identification information and an identifier of management processing contents (folder movement, mail status change, etc.). “Processing result ID”, “Type” which is information for discriminating between folder processing and mail processing, “Pre-change status” which is information indicating a state before change by management processing, and after change by management processing Information indicating the status of the user or “post-change status” which is the operation content of the user. The pre-change status and post-change status describe the status information and whether or not the various data related to the mail and folder shown in FIG. For example, when the status indicates the protection status of the mail, any numerical information of unprotected: 0, protected: 1, no change: 2 is expressed as the status. That is, the change is expressed as 1 for protection, the change is expressed as 0 for unprotection, and the change operation of the mail protection state is expressed as 2. In addition, there is information (for example, processing order ID and processing time information) that can determine the time series, and a plurality of management processing information that is the same processing result ID for the same mail ID or folder ID. In some cases, it is defined so that it is possible to determine which management processing information has been generated first.

  The management processing information aggregating unit 307 is based on status information after management processing of a plurality of management processing information having the same identification information as management processing information among the management processing information held by the management processing information holding unit 309. Perform aggregation processing to be consolidated. Here, the aggregation processing refers to the status after management of a plurality of management processing information having the same identification information of the management processing target among the management processing information held by the management processing information holding unit 309, and This is processing for specifying the state after the latest management processing for the target. In the aggregation process, not only the state after the latest management process but also the state information before the oldest management process is managed for the management process target. That is, the management processing information subjected to the aggregation processing has the data structure shown in FIG. 5 structurally, holds the latest status information after the management processing as the status after the change, The state information before the old management process is retained. By having state information before management processing and state information after management processing, when a plurality of management processing information is consolidated into one management processing information, the management processing that has not been changed in any of the plurality of management processing It is possible to prevent the state change from being missed.

  The synchronization information output unit 308 is information for synchronizing the mail data held by the mail server 100 and the mail data held by the communication terminal device 300 based on the result of the aggregation processing by the management processing information aggregation unit 307. The synchronization information is output to the mail server 100. The management processing information holding unit 309 is a database that holds management processing information.

(Configuration of mail server 100)
Next, the mail server 100 will be described in detail. FIG. 6 is a block diagram showing functions of the mail server 100. The mail server 100 includes a communication unit 101, a mail reception unit 102, a mail transmission unit 103, a synchronization processing information acquisition unit 104, a synchronization processing unit 105, and a mail related information holding unit 106.

  The communication unit 101 communicates with the communication terminal device 300 and an external server. Specifically, the communication unit 101 receives a new mail from an external server or transmits a mail requested to be transmitted from the communication terminal device 300 to the external server. In addition, the communication unit 101 receives synchronization information from the communication terminal device 300.

  The mail receiving unit 102 receives a new mail from the external server via the communication unit 101.

  The mail transmission unit 103 transmits the mail received from the communication terminal device 300 to the external server via the communication unit 101. In addition, the mail transmission unit 103 registers the mail received from the communication terminal device 300 in the mail related information holding unit 106.

  The synchronization processing information acquisition unit 104 acquires synchronization information from the communication terminal device 300 via the communication unit 101.

  The synchronization processing unit 105 updates the information held in the mail related information holding unit 106 by using the synchronization information acquired by the synchronization processing information acquisition unit 104. Thereby, the mail server 100 can synchronize with the information which the communication terminal device 300 hold | maintains.

  The mail related information holding unit 106 holds mail data and folder data. The mail data and folder data held by the mail related information holding unit 106 include data in which information for identifying the user is added to each data held by the mail related information holding unit 303 of the communication terminal device 300. Associated data.

  Next, a method of performing aggregation processing based on management processing information according to mail operation by a user of the communication terminal device 300 and outputting synchronization information based on the aggregation processing result will be described with reference to FIG. Note that mail status changes, folder movements, and mail deletion operations are aggregated. The mail statuses here are read status, protected status, reply status, forwarding status, and reply required status. A general term.

  It is assumed that an operation as shown in FIG. 7 is performed based on an operation request from the user of the communication terminal device 300. Specifically, the folder belonging to mail A is moved to Folder 1, the status of mail B is changed from unread to read, the folder belonging to mail C is moved to Folder 2, and the folder belonging to mail D is moved to Folder 1. Change the status of mail A from unread to read, change the status of mail A from read to unread, move the folder of mail A to Folder2, and change the status of mail E from unprotected to protected , Delete mail B. Based on the above operation, the management processing unit 304 updates the mail data. For example, if the folder belonging to the mail A is moved to Folder 1 by the above operation, the management processing unit 304 updates the mail belonging folder ID of the mail data corresponding to the mail A to the folder ID corresponding to Folder 1.

  The management processing information generation unit 306 generates management processing information according to the processing of the management processing unit 304. For example, when the folder to which mail A belongs is moved from Folder 1 to Folder 2, the management processing information generation unit 306 describes the mail ID of mail A in the management processing information and moves the processing result ID of management processing information to the folder. ID corresponding to the processing of the above, the type as type information corresponding to the mail processing, the status before change is information indicating Folder1 which is the folder before change (for example, Folder ID of Folder1), and the status after change is changed to Management processing information is generated as information indicating Folder2 as a folder (for example, Folder ID of Folder2).

  Then, when a predetermined server transmission condition (when the management processing information reaches a predetermined number, an explicit operation, a mail transmission / reception request, a system event, etc. after a predetermined time elapses), the management processing information aggregating unit 307 Among the management processing information held by the management processing information holding unit 309, aggregation is performed based on the status information after the management processing of a plurality of management processing information having the same identification information.

  Specifically, the management processing information aggregating unit 307 acquires a plurality of management processing information for each mail ID of the management processing information, and among the management processing information that is the same processing result ID among the acquired management processing information. The latest status of each management processing content in each mail is specified by referring to the status after the change of the latest management processing information.

  Then, the management processing information aggregating unit 307 refers to the status before change of the oldest management processing information among the management processing information having the same processing result ID, and the latest status for each management processing content in each mail. In comparison, if the latest status of each management processing content in each mail and the status before change of the oldest management processing information are the same, it is determined that the status has not been changed as a result. It is determined that the state has been changed to the latest state for each management processing content.

  In the case of the example shown in FIG. 7, the status change of the mail A has been changed from unread to read once and then changed from read to unread. The aggregation unit 307 determines that there is no change. Regarding the folder movement of the mail A, since it has moved to Folder 1 after having moved to Folder 1 first, the management processing information aggregating unit 307 finally determines that the movement is to Folder 2. Since there is no management processing information regarding deletion of mail A, the management processing information aggregating unit 307 determines that there is no deletion. Regarding the status change of the mail B, since there is only a change from unread to read, the management processing information aggregation unit 307 determines that the change is to read. Regarding the folder movement of the mail B, since there is no management process information regarding the folder movement, the management process information aggregating unit 307 determines that there is no change. Further, regarding the deletion of the mail B, since there is management processing information about the deletion, the management processing information aggregating unit 307 determines that the mail B has been deleted.

  Regarding the status change of the mail C, since there is no status change management processing information, the management processing information aggregating unit 307 determines that there is no change. Regarding the folder movement of the mail C, since there is only movement to Folder2, the management processing information aggregating unit 307 determines that the movement is to Folder2. Regarding deletion of the mail C, since there is no management processing information regarding deletion, the management processing information aggregating unit 307 determines that it has not been deleted. Regarding the status change of the mail D, since there is no management processing information regarding the status change, the management processing information aggregating unit 307 determines that there is no change. Regarding the folder movement of the mail D, since there is only movement to Folder1, the management processing information aggregating unit 307 determines that the movement is to Folder1. Regarding the deletion of the mail D, since there is no management processing information regarding the deletion, the management processing information aggregating unit 307 determines that it has not been deleted.

  Regarding the status change of the mail E, since there is a change operation to mail protection, the management processing information aggregating unit 307 determines that the change is to mail protection. Regarding the folder movement of the mail E, since there is no management processing information regarding the folder movement, the management processing information aggregation unit 307 determines that there is no change. Regarding the deletion of the mail E, since there is no management processing information about the deletion, the management processing information aggregating unit 307 determines that it has not been deleted.

  Then, the synchronization information output unit 308 outputs the synchronization information for each command that is a processing content command based on the aggregation result. In the example of FIG. 7, the command information for deletion, the command information for folder movement, and the command information for status change are divided.

  Since it is the mail B that has been deleted, the synchronization information output unit 308 outputs information in the form of a command for deleting the mail B to the mail server 100.

  Since the folder movement is performed for mail A, mail C, and mail D, the synchronization information output unit 308 receives information on the command format including the identifier of each mail and the information of the destination folder. It transmits to the mail server 30. Specifically, the mail A and the mail C perform the folder movement to Folder2, and the mail D performs the folder movement to Folder1, so that the command indicating that the mail A and the mail C move to Folder2, and the mail D Is output to the mail server 100 as information for synchronization indicating that the command is moved to Folder1.

  The mail statuses are changed in the mail B and the mail E, but since the mail B is deleted, the synchronization information output unit 308 determines the synchronization information for the status change of the mail B. The command format information indicating the status change of the mail E is output to the mail server 100 as synchronization information. As described above, the synchronization information output unit 308 excludes synchronization information for processing other than mail deletion related to mail that has been deleted from the output target, so that substantially unnecessary synchronization information is sent to the mail server 100. Notification can be prevented.

(Management processing of communication terminal device 300 and synchronization information output processing)
Next, a procedure for outputting the contents operated by mail by the user of the communication terminal device 300 as synchronization information will be described with reference to the flowchart shown in FIG. FIG. 8 is a flowchart showing a management process and a synchronization information output process executed by the communication terminal apparatus 300 of the information processing system 10 according to the present embodiment. Here, the synchronization information output process refers to a process of outputting the synchronization information based on the result of the aggregation process. Hereinafter, each step will be described.

  First, the mail display control unit 301 displays a mail list screen based on the user's request (step S1). When there is an operation request for mail data or a folder, the management processing unit 304 accepts the operation request. (Step S2), a management process corresponding to the operation request is executed (Step S3).

  The management process information generation unit 306 generates management process information including identification information (mail ID), a process result ID, a pre-change status, and a post-change status that are targets of the mail management process (step S4). .

  When the predetermined server transmission condition is met (step S5; Yes), the management process information aggregation unit 307 executes the aggregation process using the management process information held by the management process information holding unit 309 (step S6). The synchronization information output unit 308 divides the synchronization information for each management processing content (step S7), and outputs the divided synchronization information to the mail server 100 (step S8).

  If the mail server 100 executes the synchronization process using the synchronization information, as a result of the synchronization process failing (step S9; No), an error process is executed (step S10). As the error processing, the synchronization information output unit 308 transmits the synchronization information to the mail server 100 again.

  When the mail server 100 succeeds in the synchronization process using the synchronization information (step S9; Yes), the management process information corresponding to the synchronization information is deleted.

  If there is management process information not reflected in the mail server 100 (step S12; Yes), the process moves to step S6, and if there is no management process information not reflected in the mail server (step S12; No), the process is terminated. To do.

  Next, the effect of the communication terminal device 300 according to the present embodiment will be described. According to the communication terminal device 300, communication connection is possible with the mail server 100 that distinguishes and holds the mail data of the communication terminal device 300 for each folder, and the mail related information holding unit 303 distinguishes the mail data for each folder. The management processing unit 304 performs management processing of mail data and folder data, and the management processing information generation unit 306 includes identification information (mail ID or folder ID) of mail data or a folder to be managed. Management processing information including the processing result ID and the changed status (status information after management processing or user operation content) is generated, and the management processing information holding unit 309 holds the management processing information and collects the management processing information. The unit 307 sets the same identification information for management processing among the management processing information held by the management processing information holding unit 309. Aggregation processing is performed for aggregation based on the changed status of a plurality of management processing information, and the synchronization information output unit 308 retains the mail data held by the mail server 100 and the communication terminal device 300 based on the result of the aggregation processing. Information for synchronizing with the mail data to be synchronized is output to the mail server 100.

  As described above, the communication terminal device 300 aggregates the management processing information held by the management processing information holding unit 309 based on the changed status of a plurality of management processing information having the same identification information as the management processing target. Since the synchronization information based on the aggregated result is output to the mail server 100, when the management process is performed a plurality of times, only the synchronization information regarding the latest state is output, and the management process is performed. The communication load between the communication terminal device and the mail server can be reduced compared with the case where the synchronization information is notified to the mail server one by one.

  In addition, the aggregation process refers to the changed status of a plurality of management process information having the same identification information of the management process target among the management process information held by the management process information holding unit 309, This is processing for specifying the state after the latest management processing. In this case, the communication terminal device 300 refers to the status after the change of the plurality of management processing information and identifies the state after the latest management processing for the management processing target, so that each time the management processing is performed, the mail server The communication load between the communication terminal device 300 and the mail server 100 can be reduced as compared with the case of notifying the server.

  The management process information further includes a pre-change status, and executes an aggregation process using the pre-change status and the post-change status. In this case, since the management processing information also has a status before change that is information before the change, the communication terminal apparatus 300 compares the information before the change with the latest state to determine whether or not the information has been changed. It is possible to make a determination, and the management process is performed a plurality of times. As a result, the mail server 100 and the mail server 100 are not informed about the process that does not change from the original state, and information about the mail between the communication terminal apparatus 300 and the mail server 100 The communication load during the synchronization process can be reduced.

  Also, the management processing information aggregating unit 307 determines that the management processing target has not been changed when the status before aggregation of the oldest management processing information among the management processing information to be aggregated is the same as the aggregated information. Then, the synchronization information output unit 308 excludes the aggregation result determined not to be changed by the management processing information aggregation unit 307 from the synchronization information.

  In this way, the communication terminal device 300 identifies the latest change state by the management process, and if the state after the latest management process by the management process is the same as the pre-change status of the oldest management process information, Since it is determined that the processing has not been performed, and the synchronization information corresponding to the state after the latest management processing by the management processing is not output to the mail server 100, the management processing is performed a plurality of times. The processing that does not change is not notified to the mail server 100, and the communication load at the time of synchronization processing of information about the mail between the communication terminal device 300 and the mail server 100 can be reduced.

  Further, the synchronization information output unit 308 outputs the synchronization information in which the results aggregated with the management processing target identification information are aggregated for each command corresponding to the management processing content. In this case, since the communication terminal device 300 transmits in units of management processing, the number of communication is reduced and the communication load can be reduced as compared with the case where transmission is performed every time management processing occurs. it can. Moreover, since the communication terminal apparatus 300 transmits for each command, the mail server 100 can output the synchronization information in a format that facilitates the synchronization process.

(Other embodiments)
In addition to the above-described embodiment, the synchronization information output unit 308 may first output synchronization information corresponding to a management process with a high priority. For example, when a mail is deleted after a folder belonging to a certain mail is changed, the deletion may be synchronized first, and the subsequent folder movement may not be synchronized. In this case, the synchronization process can be efficiently performed by performing the synchronization process for deletion first. Therefore, the deletion process has a higher priority. As described above, the synchronization information output unit 308 outputs the synchronization information according to the priority, so that the mail server 100 can efficiently execute the synchronization process. In addition, it is good also as a structure which can restore | restore the state before deletion about the mail data which moved to the trash folder (folder which stores the mail designated deletion) temporarily, without applying the above-mentioned mounting.

  In addition to the above-described embodiment, the synchronization information output unit 308 may determine the number of pieces of mail synchronization information to be transmitted at a time based on the number that the mail server 100 can execute each process together. . For example, when the mail server 100 can process 1000 deletion processes with a single execution command, the synchronization information output unit 308 outputs the synchronization information related to the deletion process in units of 1000 or less. . In this case, since the communication terminal device 300 outputs in units that can be processed at one time by the mail server 100, it is not necessary to distribute the synchronization information acquired by the mail server 100, so that the synchronization processing can be performed efficiently.

  In the above-described embodiment, a case has been described in which management processing information for management processing for mail data is generated. However, it may be applied to management processing for folder data.

  In the above-described embodiment, the case where the management processing information aggregating unit 307 first aggregates for each mail has been described. However, the management process information aggregation unit 307 may first aggregate for each command.

  In the above-described embodiment, the case has been described in which the synchronization information output unit 308 outputs the synchronization information in a state of being aggregated for each command after being aggregated for each mail. However, the synchronization information is not aggregated for each command. You may make it output.
