  When the service provided from the service management server 10 is used in its own terminal, the process execution unit 213 executes a process for the service. For example, when the process execution unit 213 executes the mail application 251 and acquires service data from the service management server 10, the process execution unit 213 stores the acquired data in the storage unit 25. Further, the process execution unit 213 causes the display unit 24 to display a service use screen that is a display screen during use of the service, based on the service data 252. In addition, the process execution unit 213 transmits the service data 252 stored in the storage unit 25 to the service management server 10.

Next, the operation of the service management system 1 will be described.
FIG. 6 is a sequence diagram illustrating an operation example when the service usage status is presented based on usage status data in the service management system 1. Here, an operation example in the case where the user terminal 20a presents the service usage status in the service management system 1 will be described. Before the operation described below, it is assumed that the usage management table 131 is in the state shown in FIG.

  First, the service management server 10 determines whether or not to transmit service data based on the service data DB 132 to the user terminal 20a whose user ID is “UID001” (step S1). For example, the service management server 10 sends service data to the user terminal 20a when an e-mail to be transmitted to the user terminal 20a is generated or a data transmission request related to a mailbox is received from the user terminal 20a. Determine to send.

If the service management server 10 determines that the service data is transmitted to the user terminal 20a (step S1; YES), the service management server 10 refers to the usage management table 131, shares the user account with the user terminal 20a, and uses the mail service. The user terminal 20 in the middle is specified (step S2). Here, it is written in the usage management table 131 that the user terminals 20a, 20b, 20c and 20d share the user account. Further, it is written in the usage management table 131 that the user terminals 20a, 20b, 20c and 20d are using the mail service but the user terminal 20d is not using the mail service.
Therefore, in the process of step S2, the service management server 10 specifies the user terminals 20a, 20b, and 20c.

  Next, the service management server 10 transmits the service data stored in the service data DB 132 and the usage status data for the user terminal 20 identified in the process of step S2 to the user terminal 20a (step S3). The usage status data here includes information indicating that the three user terminals 20a, 20b, and 20c are using the mail service.

  When the user terminal 20 acquires service data and usage status data from the service management server 10 (step S4), the user terminal 20 updates the service data 252 based on the acquired service data (that is, performs a synchronization process), and the service is performed. The usage screen is displayed on the display unit 24. Also, the user terminal 20 presents the service usage status based on the usage status data acquired from the service management server 10 during the display of the service usage screen (step S5).

  FIG. 7 is a diagram illustrating a service use screen displayed by the process of step S5. As shown in FIG. 7A, on the service use screen SC <b> 1, the message “Mail service is currently in use: 3” is displayed in the upper part of the display area of the display unit 24. The three user terminals 20 here correspond to the user terminals 20a, 20b and 20c. The user who has seen the service use screen SC1 can grasp that there are a total of three user terminals 20 using the mail service while browsing the use screen of the mail service. On the other hand, the user terminal 20a does not display information on the user terminal 20 not using the mail service (in this case, information on the user terminal 20d).

  In the service management system 1, the above processing steps are repeatedly executed to update information presented on the user terminal 20. For example, when the user terminal 20c logs out from the mail service and ends use of the mail service, the service management server 10 updates the use management table 131 to the configuration shown in FIG. Specifically, the service management server 10 rewrites the presence / absence information field associated with the terminal ID “MID-c” from “◯” to “×”. Thereafter, the user terminal 20a that has acquired the usage status data causes the display unit 24 to display the service usage screen SC1 illustrated in FIG. 7B in the process of step S5 based on the acquired usage status data. As shown in FIG. 7B, on the service use screen SC1 here, a message “using mail service: 2” is displayed. The two user terminals 20 correspond to the user terminals 20a and 20b. Thereby, the user can grasp that his / her own user terminal 20 using the mail service has changed to a total of two while browsing the use screen of the mail service.

When the user terminal 20 is displaying the service use screen on the display unit 24, the user terminal 20 does not present the number of user terminals 20 using the mail service at the top of the display area of the display unit 24, but displays other displays. The number of user terminals 20 may be presented by the method.
FIG. 9 is a diagram illustrating another example of the service use screen displayed by the user terminal 20 by performing the process of step S5. As shown in FIG. 9A, first, the user terminal 20 displays the service usage screen SC2 without presenting the usage status of the mail service. Next, it is assumed that the user performs an operation to instruct the user terminal 20 to display a menu for instructing execution of a predetermined process. In response to this operation, the user terminal 20 changes the display to the service use screen SC2 shown in FIG. In this service use screen SC2, a message “using mail service: 3” is included in a menu (submenu) M including a plurality of items displayed on the service use screen. The meaning of this message is the same as in the display example shown in FIG.
Here, the menu M includes a plurality of items “option”, “setting change”, and “help”, but may be other items.

<Presentation results>
The user terminal 20 does not present the number of user terminals 20 sharing the user account and using the mail service, but may present information on the past use of the mail service at the user terminal 20. Good. In this case, the service management server 10 transmits usage status data including usage records based on the usage management table 131 in the process of step S3. And the user terminal 20 should just acquire the utilization condition data containing a utilization track record by the process of step S4, and should show the utilization condition of a service by the process of step S5.

When the service management server 10 changes to information written in the usage management table 131, the service management server 10 may transmit usage status data for notifying the change. FIG. 14A is a sequence diagram showing a procedure for providing a mail service in the service management system 1.
The service management server 10 first determines whether there is a user terminal 20 that has changed in the information written in the usage management table 131 (step S1a). If the service management server 10 determines that no change has occurred in the information written in the usage management table 131 (step S1a; NO), the service management server 10 stands by without transmitting usage status data. On the other hand, if the service management server 10 determines that there is a user terminal 20 in which the information written in the usage management table 131 has changed (step S1a), the process proceeds to the process of step S2. In step S2, the service management server 10 shares the user account with the user terminal 20 and specifies the user terminal 20 that is using the mail service. Then, the service management server 10 transmits usage status data to the identified user terminal 20 (step S3a). Here, the service management server 10 transmits usage status data without transmitting service data. Since the presentation of the service usage status at the user terminal 20 may be the same as in the above operation example, the description thereof is omitted here. According to this transmission example, the user terminal 20 can easily present the service usage status based on the latest usage status data.

(Transmission example 2: Every predetermined period)
The service management server 10 may transmit usage status data each time a predetermined period elapses. FIG. 14B is a sequence diagram showing a procedure for providing a mail service in the service management system 1.
First, the service management server 10 determines whether or not a predetermined period has elapsed since the last usage status data was transmitted (step S1b). The length of the predetermined period may be any length, for example, 5 minutes. If the service management server 10 determines that the predetermined period or more has not elapsed since the last use status data was transmitted (step S1b; NO), the service management server 10 stands by without transmitting the use status data. If the service management server 10 determines that a predetermined period or more has elapsed since the last use status data was transmitted (step S1b), the service management server 10 proceeds to the process of step S2. In step S2, the service management server 10 shares the user account with the user terminal 20 and specifies the user terminal 20 that is using the mail service. Then, the service management server 10 transmits usage status data to the identified user terminal 20 (step S3b). Again, the service management server 10 transmits the usage status data without transmitting the service data. The presentation of the service usage status at the user terminal 20 may be the same as in the above operation example, and the description thereof is omitted here.
In addition, the user terminal 20 may transmit a usage status data transmission request to the service management server 10, and the service management server 10 may transmit the usage status data when the transmission request is accepted. .

  According to the embodiment described above, when one or more other user terminals 20 sharing the user account used for the service are registered in the service management server 10, the registered other Information for notifying the user of the user terminal 20 that is using the service. Here, in addition to the number of user terminals 20 that are using the service, the user terminal 20 starts using the service, the elapsed time from the start, the time of the last synchronization, or the time of the last synchronization It is also possible to present past usage record information such as the elapsed time from the terminal, the terminal type, and whether or not the latest synchronization processing has been completed. On the other hand, since the user terminal 20 does not present the information of the user terminal 20 that is not using the service, the amount of other information presented based on the usage status data does not increase. As a result, even when the user terminal 20 presents the service usage status based on the usage status data while the service usage screen is being displayed, it is difficult for the user to visually recognize each information displayed on the display unit 24. Can be suppressed. In addition, when the number of terminals being used is different from the number of user terminals 20 at hand, the user is likely to notice that his user terminal 20 is not at hand (for example, lost). The possibility that the user terminal 20 is misused by a third party can also be suppressed.

[Modification]
The present invention can be implemented in a form different from the above-described embodiment. The present invention can also be implemented in the following forms, for example. Further, the following modifications may be combined as appropriate.
(Modification 1)
In the service management system 1 of the above-described embodiment, as the past usage record of the mail service, when the use start date or the synchronization process of the mail service is performed, the elapsed time from the use start date or the date and time when the synchronization process is performed, etc. Based on the usage record regarding time, the usage status of the mail service was presented. Instead, the service management system 1 may present the usage status of the mail service based on the usage record regarding the position of the user terminal 20.

FIG. 15 is a diagram showing the configuration of the usage management table 131 of this modification. As illustrated in FIG. 15, the usage management table 131 includes “user ID”, “terminal ID”, “terminal type”, “use start date”, “last synchronization date”, and “presence information”. , A data table in which pieces of information called “service start location” and “final synchronization location” are associated with each other.
About presentation of each information of "user ID", "terminal ID", "terminal type", "use start date", and "last synchronization date", and the use status of the mail service using them, the above-described embodiment Since they may be the same, the description thereof is omitted here. In the “service start location” field of the usage management table 131, the location where the use of the mail service is started at the user terminal 20 indicated by the terminal ID associated with this field is written as the service start location. In the field of “last synchronization location” of the usage management table 131, the latest location where the service data in the own terminal is synchronized with the data in the service data DB 132 in the user terminal 20 indicated by the terminal ID associated with this field. Is written as the final synchronization location. Here, the service start location and the final synchronization location represent the name of the location, but may be any information that can identify the terminal location, such as latitude / longitude information and base station positioning results.

  In the service management system 1, the operation for presenting information about the service start location and the last synchronization location is realized by including the service start location and the last synchronization location information in the usage status data of the above-described embodiment. be able to. In addition, each information of the service start location and the final synchronization location is appropriately rewritten by the service management server 10 according to the service usage status in the user terminal 20.

(Display Example 1) Service Start Location When presenting the service start location, the user terminal 20 presents the service usage status as shown in FIG. The service use screen SC7 shown in FIG. 16A includes a character string indicating the service start location. The user terminal 20 displays the service start location based on the “service start location” information stored in the usage management table 131. The user who has seen this service start location can grasp at which location the use of the mail service is started for each user terminal 20.
Note that the meanings of the type image and the additional image are the same as those in the above-described embodiment, and thus description thereof is omitted here.

(Display Example 2) Final Synchronization Location FIG. 16B is a diagram showing a service use screen SC8 of display example 2. In display example 2, instead of the service start location in display example 1, the final synchronization location is included in service use screen SC8. The user terminal 20 displays the final synchronization location based on the “last synchronization location” information stored in the usage management table 131. The user who has seen this final synchronization location can grasp the location where the last synchronization processing has been performed in each user terminal 20. Thereby, for example, when the user loses the user terminal 20, the information on the final synchronization location can be used for finding the user terminal 20.

  As described above, the user terminal 20 can present various information as past usage records of the service. The usage record may be information other than the above as long as it is a past use record of the service. For example, the information represented by the date and time in the above-described embodiment may be represented by only the date, or the information represented by the date in the above-described embodiment may be represented by the date and time. In short, the user terminal 20 may present information indicating an elapsed period from the time when a specific process for the service is performed or the time when the process is performed. This specific process is not limited to the synchronous process, and may be any process related to the mail service, such as when the latest mail is received, transmitted, or when the setting is changed.

(Modification 2)
In the embodiment described above, the user terminal 20 presents the usage status of the mail service based on the usage status data for the own terminal and other terminals sharing the user account. Instead, the user terminal 20 presents the usage status of the mail service based on usage status data of other terminals sharing the user account with the own terminal, and does not present the usage status of the mail service for the own terminal. It may be.

(Modification 3)
When presenting the usage status of the mail service for two or more user terminals 20, the user terminal 20 may have a display mode according to the attributes or usage results of the two or more user terminals 20. As shown in the service usage screen SC9 shown in FIG. 17A, when the user terminal 20 presents it in a display mode corresponding to the type of the user terminal 20, the user terminal 20 can make other users so that the release times are in the newest order or the oldest order. The type images of the terminal 20 may be arranged. Here, the user terminal 20 may adopt another time such as the time when the user purchased, instead of the release time. Further, the user terminal 20 may refer to the model number or the like for the model, or may refer to the model name. Further, the user terminal 20 may replace the model with the release date and version of the installed OS in the order of newest or oldest. Thus, the user terminal 20 can present the usage status of the mail service in a display mode according to the attribute of the user terminal 20.

  Moreover, time is shown when the user terminal 20 presents the usage status of the mail service in a display mode corresponding to the past usage history of the mail service, as in the service usage screen SC10 shown in FIG. When presenting information, the usage status of the mail service is presented by arranging the type images of the user terminals 20 so that the times are in the newest order or the oldest order. In addition, when presenting a period, the user terminal 20 may present the usage status of the mail service by arranging the type images of the user terminals 20 so that the periods are in the order of long or short. If the location is presented as in the first modification, the user terminal 20 may present the usage status of the mail service by arranging the type images of the user terminals 20 in the order closer to or farther from the reference position such as home. Good.

(Modification 4)
The user terminal 20 may present that the use of the mail service is stopped for the user terminal 20 for which the past use record of the mail service satisfies a specific condition. FIG. 18 is a sequence diagram showing a procedure for providing a mail service in the service management system 1.
Since the user terminal 20 can specify the usage record of the other user terminals 20, for example, it is also possible to specify the user terminals 20 that have not been used much recently. Therefore, the user terminal 20 determines whether or not there is another user terminal 20 that does not use the mail service so much after the processes of steps S1 to S5 are performed (step S6). Here, when there is a user terminal 20 whose elapsed time from the time when the last synchronization is performed becomes equal to or greater than the threshold, the user terminal 20 determines that the user terminal 20 has not been used much recently. If the user terminal 20 determines in the process of step S6 that there is a user terminal 20 that does not use the mail service much (step S6; YES), the user terminal 20 indicates on the service use screen that the use of the mail service is stopped. Present (step S7). Here, as in the service use screen SC11 shown in FIG. 19A, a message “Time has passed since the last synchronization. How about stopping the service?” Is displayed. The user who sees this can log out the user terminal 20 that has been left for a long time from the mail service and prevent the unauthorized use due to the loss of the terminal.

In this modification, instead of presenting that the use of the mail service is stopped, the user terminal 20 immediately performs the synchronization process as in the service use screen SC12 shown in FIG. 19B. A message prompting the user may be presented. The user terminal 20 can display the service usage screen SC12 by changing the message displayed in the process of step S7.
In the service management system 1, the configuration of this modified example can also be applied when usage status data is transmitted according to the transmission examples 1 and 2 described above.

(Modification 5)
The service provided by the service management server 10 to the user terminal 20 is not limited to the mail service. The service provided by the service management server 10 to the user terminal 20 may be a cloud storage service (for example, a telephone book service) that provides a storage area for data other than electronic mail. The phone book service is a service involving processing using phone book data. The phone book service, for example, allows a plurality of user terminals 20 owned by the same user to refer to the contents of the phone book data or contact information included in the phone book data in response to a request from the user terminal 20 Includes services that allow users to create emails and make phone calls. In this case, as shown in FIG. 20, when the user terminal 20 displays the service usage screen for the telephone directory service, the information on the user terminal 20 that is using the service or the past usage record of the service on the user terminal 20 is displayed. It is sufficient to present information based on. That is, even when the user terminal 20 uses two or more services, it is desirable to classify each service type and present the usage status. At that time, according to the user switching operation, it may be determined which type of service usage status is presented. In addition, the service management server 10 may present information on the fact and the usage record if any service is used by another user terminal 20 without classifying the service management server 10 for each type of service.

  In addition, the service management server 10 may provide other services that share user accounts among a plurality of user terminals 20 such as services that distribute content such as music, video, and advertisements, rather than services related to cloud storage. Good. Further, the service management server 10 may provide other services that are not services that share information among the plurality of user terminals 20. The service management server 10 provides a service for sharing a user account to a plurality of user terminals 20 owned by the same user using communication, and transmits data about the service to each user terminal 20, Or received from each user terminal 20. Further, the service of the present invention is not limited to that which can be used by executing an application.

(Modification 6)
The plurality of user terminals 20 registered in the service management server 10 may not be owned by the same user. For example, in the service management system 1, attribute information indicating user attributes may be used instead of a user ID having a user identification function. This user attribute is defined by using, for example, information representing a human relationship between users (for example, the same subscriber, a family member, a student at the same school, a company colleague, etc.).
As described above, the service management server 10 may provide services by sharing user accounts between different users when handling service data that may be shared by others.

(Modification 7)
In the above-described embodiment, the configuration in which the usage situation is presented using an image may be replaced with a configuration using characters (character strings) or may be replaced with a configuration that outputs audio.
Further, the service management system 1 may not present information on past usage records of services.

(Modification 8)
In the embodiment described above, the service management server 10 performs both management of the usage management table 131 and service management based on the service data DB 132. However, these server management may be performed by separate server devices. Good. In this case, the service server may inquire the management apparatus and perform processing for presenting the service usage status based on the usage management table 131.
In the embodiment described above, each function realized by the control unit 11 of the service management server 10 and the control unit 21 of the user terminal 20 is realized by a combination of a plurality of programs, or by a combination of a plurality of hardware resources. sell.
