  Hereinafter, a portable terminal synchronization system including two portable terminals and one synchronization execution server device will be described with reference to the drawings for an embodiment of the present invention. However, the number of mobile terminals constituting the mobile terminal synchronization system is not limited to two, and a plurality of mobile terminals may be used.

[overall structure]
FIG. 1 is a diagram showing the overall configuration of the mobile terminal synchronization system 1. The mobile terminal synchronization system 1 includes two mobile terminals 10 a and 10 b that perform synchronization and a synchronization execution server device 20. The outline of the synchronization process with the mobile terminals 10a and 10b will be described with reference to FIG.

  In response to the user of the mobile terminal 10a giving an instruction to start the synchronization process, the mobile terminal 10a starts the synchronization process (not shown). Similarly, the portable terminal 10b also starts the synchronization process (not shown) in response to the user of the portable terminal 10b giving an instruction to start the synchronization process.

  The portable terminal 10a acquires synchronous operation data based on the synchronous operation performed by the user on the mobile terminal 10a, and transmits it to the synchronization execution server device 20 (300). Similarly, the mobile terminal 10b acquires synchronous operation data based on the synchronous operation performed by the user on the mobile terminal 10b, and transmits it to the synchronization execution server device 20 (301).

  Here, the synchronization operation includes an operation for simultaneously causing the plurality of mobile terminals to be synchronized to perform the same movement, an operation for simultaneously setting the plurality of mobile terminals to be synchronized to the same place, and a plurality of mobile terminals to be synchronized. There are operations for simultaneously photographing a subject from the same position, and operations for simultaneously inputting sound to a plurality of portable terminals to be synchronized.

  The synchronous operation needs to be the same not only for the operation content but also for the operation. This is because only with the operation content, portable terminals that have been operated in the past are also targeted for synchronization. Even if a plurality of portable terminals to be synchronized perform the same movement or the like at the same time, an error occurs because the synchronization operation data is acquired by different portable terminals. Therefore, when the synchronization operation data is within a predetermined error, it is assumed that a plurality of portable terminals are simultaneously performing the same movement or the like.

  Further, the synchronization operation data based on the synchronization operation performed by the user on the mobile terminals 10a and 10b is data characterizing the synchronization operation, and the data and the synchronization operation obtained as a result of the user performing the synchronization operation on the mobile terminal. Date and time. The data obtained as a result of the synchronization operation is the acceleration that occurs when the mobile device is moved if the synchronization operation is an operation that causes a plurality of mobile devices to synchronize. If it is operation which makes the some portable terminal the same place, it is the position of a portable terminal. In addition, if the synchronization operation is an operation to shoot a subject from the same position on each of the plurality of mobile terminals that are to be synchronized, the synchronization operation is an image captured by the camera of the mobile terminal. If it is operation which outputs a sound simultaneously to a portable terminal, it is the voice etc. which were input into the portable terminal.

The synchronization execution server device 20 determines whether the synchronization operation data received from the mobile terminal 10a and the synchronization operation data received from the mobile terminal 10b are within a predetermined error. Specifically, it is determined whether or not the data obtained as a result of the synchronization operation and the date and time when the synchronization operation was performed are within a predetermined error. The predetermined error needs to be determined in advance by a system administrator or the like. For example, in the case of acceleration when the synchronization operation is an operation that causes a plurality of mobile terminals to be synchronized to move in the same manner, the difference between the acceleration of the mobile terminal 1a and the acceleration of the mobile terminal 10b is ± 5 mm / s ^2. It is determined that up to is the error.

  If the synchronization execution server device 20 determines that the synchronization operation data with the portable terminals 10a and 10b is within a predetermined error, the synchronization execution server device 20 activates the synchronization of the portable terminals 10a and 10b, and indicates the result that the synchronization has been activated. 10b (310, 311). Here, the activation of synchronization means that the mobile terminal recognizes the mobile terminal to be synchronized and becomes in a state where data can be synchronized with each other. When the mobile terminal 10a, 10b receives the result that the synchronization is activated from the synchronization execution server device 20, the mobile terminal 10a, 10b transmits / receives data to be synchronized via the synchronization execution server device 20 (320, 321). .

  On the other hand, if the synchronization execution server device 20 determines that the synchronization operation data with the portable terminals 10a and 10b is not within a predetermined error, the synchronization of the portable terminals 10a and 10b is not activated, and the synchronization is not activated. The result is transmitted to each of the mobile terminals 10a and 10b (310, 311). In this case, the mobile terminals 10 a and 10 b cannot transmit and receive data via the synchronization execution server device 20.

  When there is another mobile terminal in the mobile terminal synchronization system 1, the synchronization execution server device 20 receives the synchronization operation data from the other mobile terminal as well as the mobile terminals 10a and 10b. Then, the synchronization execution server device 20 determines whether each of the synchronization operation data received from the received mobile terminals 10a and 10b and the other mobile terminal is within a predetermined error. The synchronization execution server device 20 activates synchronization between portable terminals whose synchronization operation data is within a predetermined error, and the synchronization operation data indicates a result of synchronization activation for portable terminals having the same synchronization operation data. A result indicating that the synchronization has not started is transmitted to the mobile terminal that is not within the predetermined error.

  By identifying the mobile terminal that performs synchronization based on whether or not the synchronization operation data of the mobile terminal is within a predetermined error, there is no need to obtain information for identifying the mobile terminal that performs synchronization in advance, and there is a trouble in synchronization. It does not take. Further, since the synchronization operation data is data characterizing the synchronization operation, the synchronization can be activated by performing the same synchronization operation on the mobile terminal to be synchronized. As a result, the synchronization operation is intuitive and simple for the user of the mobile terminal.

[Example]
FIG. 2 is a diagram illustrating an example of a synchronization operation according to each embodiment of the present invention. Hereinafter, the mobile terminal is assumed to be a mobile phone. FIG. 2A shows that the cellular phone 11a and the cellular phone 11b are shaken in an overlapping manner. Since the mobile phone 11a and the mobile phone 11b are overlapped, both of them move almost at the same time. Therefore, the acceleration of the synchronization operation data, which is a condition for starting the synchronization, and the time when the synchronization operation is performed are within a predetermined error between the mobile phone 11a and the mobile phone 11b, and the synchronization of both can be started. As described above, since the synchronization can be started simply by overlapping and shaking the mobile phones to be synchronized, the synchronization operation can be made intuitive and simple for the user. The first embodiment will be described later using the example of the synchronous operation shown in FIG.

  FIG. 2B shows that the mobile phone 12a and the mobile phone 12b are in contact with each other. Since the mobile phone 12a and the mobile phone 12b are in contact with each other, they are present at substantially the same position at the same time. Therefore, the position of the mobile phone of the synchronization operation data, which is a condition for starting the synchronization, and the date and time when the synchronization operation was performed are within a predetermined error between the mobile phone 12a and the mobile phone 12b, and the synchronization of both is started. Can do. As described above, since the synchronization can be started only by bringing the mobile phones to be synchronized with each other, the synchronization operation can be made intuitive and simple for the user. The second embodiment will be described later using the example of the synchronization operation shown in FIG.

  FIG. 2C is a diagram showing images taken by the mobile phone 13a and the mobile phone 13b in a state where they are overlapped. Since the cellular phone 13a and the cellular phone 13b are overlapped and photographed simultaneously by the respective cameras, the photographed images are substantially the same. Therefore, the image taken by the mobile phone camera of the synchronization operation data, which is the condition for starting the synchronization, and the date and time when the image was taken are within a predetermined error between the mobile phone 13a and the mobile phone 13b. Both synchronizations can be activated. As described above, since the synchronization can be started simply by overlapping the mobile phones to be synchronized and photographing the subject, the synchronization operation can be made intuitive and simple for the user. The third embodiment will be described later using the example of the synchronization operation shown in FIG.

  FIG. 2D is a diagram showing that the user is inputting voice toward both the mobile phone 14a and the mobile phone 14b. Since the user inputs voice toward both the mobile phone 14a and the mobile phone 14b, the voices input to both are the same. Therefore, the voice input to the mobile phone, which is the synchronization operation data under which the synchronization is activated, and the time when the voice is input are within a predetermined error between the mobile phone 14a and the mobile phone 14b. Synchronization can be activated. As described above, since the user can activate the synchronization only by inputting voices to a plurality of mobile phones to be synchronized, the synchronization operation can be made intuitive and simple for the user. . The fourth embodiment will be described later using the example of the synchronous operation shown in FIG.

(First embodiment)
In the first embodiment, when the synchronization operation is an operation for causing a plurality of mobile terminals to synchronize to move in the same manner, for example, an operation of shaking the two mobile phones shown in FIG. The case where it is is demonstrated.

  FIG. 3 is a diagram showing a functional configuration of the synchronization execution server device 20 and the two mobile phones 15 constituting the mobile phone synchronization system 2 according to the first embodiment of the present invention. First, the functional configuration of the mobile phone 15 will be described. When two mobile phones 15 are distinguished, one mobile phone 15 is called a mobile phone 15a, and the other mobile phone 15 is called a mobile phone 15b. However, the mobile phone 15a and the mobile phone 15b have the same functional configuration.

[Functional Configuration of Mobile Phone in First Embodiment]
The mobile phone 15 includes a synchronization activation unit 101, an acceleration sensor unit (synchronization operation data acquisition unit) 102, an acceleration data transmission unit (synchronization operation data transmission unit) 103, a result reception unit 104, a data transmission / reception unit 105, And a data storage unit 106.

  The synchronization activation unit 101 receives a user's instruction to start the synchronization process and starts the synchronization process. The user's instruction to start the synchronization process includes, for example, pressing a button of the mobile phone to which the function for starting the synchronization process is assigned, opening a folding mobile phone, and the like. Further, the synchronization activation unit 101 may automatically start the synchronization process when a predetermined condition is satisfied instead of the user's instruction to start the synchronization process. Here, the predetermined condition is, for example, that the mobile phone exists in a specific place.

  When the user gives an instruction to start the synchronization process, it can be instructed whether to transmit data stored in the mobile phone or receive data stored in another mobile phone. When instructing whether to transmit or receive data in accordance with the instruction to start the synchronization process, after the synchronization is activated, the mobile phone can only perform either instructed transmission or reception.

  The acceleration sensor unit 102 measures the acceleration when the mobile phone 15 is shaken. There are three types of acceleration sensors, mechanical, optical, and semiconductor, and any of them may be used. An acceleration sensor provided in the mobile phone 15 is used as the acceleration sensor unit 102 in order to detect the tilt and movement of the mobile phone.

  The acceleration sensor unit 102 measures the acceleration when the mobile phone is shaken after the synchronization processing is started by the synchronization activation unit 101. This is to exclude the case where the mobile phone is shaken except for the synchronization operation.

  The acceleration data transmission unit 103 transmits the acceleration measured by the acceleration sensor unit 102 and the measurement date and time when the acceleration is measured by the acceleration sensor unit 102 to the synchronization execution server device 20 as acceleration data (synchronization operation data). In the case of instructing the start of the synchronization process, if the mobile phone to be transmitted or received is designated, the information is also included in the acceleration data. Further, identification information for specifying the mobile phone 15 may be transmitted together with the acceleration data, and a mobile phone (synchronous mobile terminal) that performs synchronization may be stored in the synchronization execution server device 20.

  As a result of determining whether or not there is a mobile phone 15 that performs synchronization in the synchronization execution server device 20 based on the acceleration data received from the acceleration data transmission unit 103, the result receiving unit 104 determines whether or not synchronization is activated. Receive the result. When the result receiving unit 104 receives a result indicating that the synchronization is started from the synchronization execution server device 20, the process proceeds to the data transmitting / receiving unit 105. On the other hand, when the result receiving unit 104 receives a result indicating that the synchronization has not started from the synchronization execution server device 20, the synchronization processing is terminated. At this time, a message indicating that synchronization cannot be performed may be displayed on the display of the mobile phone 15.

  The data transmission / reception unit 105 transmits the data stored in the data storage unit 106 to the synchronization execution server device 20. The synchronization execution server device 20 that has received the data compares the data received from the mobile phone that has started synchronization, and extracts difference data as a comparison result. Here, the difference data refers to different data among the data stored in the data storage unit 106 of one mobile phone 15a that has been activated and the data storage unit 106 of the other mobile phone 15b. is there. In addition, the data transmitting / receiving unit 105 of one mobile phone 15a receives the difference data extracted by the synchronization execution server device 20, and the same data storage unit 106 is synchronized with the other mobile phone 15b that has started synchronization. It becomes a thing.

  The difference data when there are three or more data storage units will be described. The data storage units are A, B, and C, respectively. The difference data of the data storage unit A, the data storage unit B, and the data storage unit C are (1) difference data compared in the data storage unit A and the data storage unit B, and (2) data storage unit B and the data storage unit C. (3) The difference data compared in the data storage unit A and the data storage unit C are extracted. Each extracted difference data is synchronized by transmitting and receiving via the data synchronization unit 204 in order, and becomes the same. However, after the difference data of (1) and (2) are synchronized in this order, the difference data of (3) disappears, so that the difference data of (3) is not transmitted / received.

  The data storage unit 106 is a data storage unit provided in the mobile phone 15 and stores addresses, music, images, and the like.

  The one mobile phone 15a and the other mobile phone 15b end the synchronization process when the difference data has been transmitted or when the difference data has been received.

[Functional configuration of synchronous execution server]
Next, the functional configuration of the synchronization execution server device 20 will be described. The synchronization execution server device 20 includes an acceleration data reception unit (synchronization operation data reception unit) 201, an acceleration data determination unit (determination unit) 202, a result transmission unit 203, and a data synchronization unit 204.

  The acceleration data receiving unit 201 receives acceleration data from the acceleration data transmitting unit 103 of the mobile phone 15.

  The acceleration data determination unit 202 determines whether the acceleration data received by the acceleration data reception unit 201 is within a predetermined error. Specifically, each of the data included in the acceleration data, for example, whether or not the acceleration and the measurement date / time are within a predetermined error is determined, and if the acceleration and the measurement date / time are within a predetermined error, the acceleration data Is determined to be within a predetermined error. By providing the acceleration data determination unit 202, it is possible to specify a mobile phone to be synchronized with the mobile phone 15 using the acceleration data without specifying a plurality of mobile phones to be synchronized in advance. The mobile phone to be performed can be identified and synchronized.

  Then, the acceleration data determination unit 202 specifies a plurality of mobile phones 15 that have been determined that the acceleration data is within a predetermined error. Synchronization is activated between the plurality of mobile phones 15 in which the acceleration data determination unit 202 determines that the acceleration data is within a predetermined error.

  When the acceleration data includes data indicating whether the mobile phone 15 that transmitted the acceleration data is a mobile phone that performs transmission or reception, the acceleration data that is transmitted is used as a reference, The mobile phone 15 in which this data is the received acceleration data and the data other than this data is the same is specified. Conversely, acceleration data from which this data is received may be used as a reference.

  The result transmission unit 203 transmits the determination result of the acceleration data determination unit 202 to the mobile phone 15. Specifically, a result indicating that the synchronization is activated is transmitted to the mobile phone 15 in which the acceleration data determination unit 202 determines that the acceleration data is within a predetermined error. The result transmitting unit 203 may transmit a result indicating that the synchronization has not been activated to the mobile phone 15 in which the acceleration data determining unit 202 has not determined that the acceleration data is within a predetermined error. When the acceleration data includes data indicating whether the mobile phone 15 that transmitted the acceleration data is a mobile phone that performs transmission or reception, the data may be included in the result.

  The data synchronization unit 204 compares the data storage units of the cellular phones that have started synchronization, and extracts difference data as the comparison result. Specifically, data in the data storage unit 106 is received from the data transmitting / receiving unit 105 of each of the one mobile phone 15a and the other mobile phone 15b, and the received data is compared. Further, the data synchronization unit 204 transmits difference data as a comparison result to one mobile phone 15a and the other mobile phone 15b.

[Synchronous processing flow]
FIG. 4 is a flowchart of the synchronization process according to the first embodiment of the present invention.

S18: If the acceleration data determination unit 202 determines in step S16 that the two acceleration data are within a predetermined error, the acceleration data determination unit 202 identifies the two mobile phones 15 that transmitted the acceleration data as mobile phones that perform synchronization. .

  S20: When it is determined in step S16 that the two acceleration data are within a predetermined error, the result transmission unit 203 activates synchronization in the mobile phone 15 specified as the mobile phone that performs synchronization in step S18. Send the result to the effect. If the acceleration data determination unit 202 determines in step S16 that the two acceleration data are not within a predetermined error, the fact that synchronization has not been activated in the two mobile phones 12 that transmitted the acceleration data is indicated. Send the result.

S22: The result receiving unit 104 receives the result transmitted from the result transmitting unit 203 of the synchronization execution server device 20 in step S20.
S24: The result receiving unit 104 determines whether or not synchronization is activated based on the result received in step S22. If the determination result is YES, the process proceeds to step S26, and if the determination result is NO, the process ends.
S26: The data transmitting / receiving unit 105 performs a synchronization process in which the data storage unit 106 and the data storage unit 106 of the other mobile phone identified in step S18 are the same. Details will be described using a flow shown in FIG.
