Even if it exists, data can be received reliably.

  The teachings of the present invention can be readily understood by considering the following detailed description with reference to the accompanying drawings shown for illustration only. Subsequently, embodiments of the present invention will be described with reference to the accompanying drawings. Where possible, the same parts are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 shows a configuration of an information storage system 1 including a mobile phone 10 (mobile communication terminal) and a mobile phone 10 according to the present embodiment. The cellular phone 10 can transmit / receive data to / from the information board 20 (storage device) by short-range wireless communication. In addition, the cellular phone 10 can transmit and receive data with the data transmission server 30 by mobile communication. Specifically, the mobile phone 10 includes a CPU and a memory. Each function of the mobile phone 10 will be described later.

  The information board 20 is a device that can store electronic data and can display the contents (text, images, etc.) of the electronic data on a display device such as a monitor provided in the information board 20. The user can know the contents of the electronic data by looking at the displayed contents. The information board 20 is normally fixedly installed at the home of the user of the mobile phone 10. The short-range wireless communication between the information board 20 and the mobile phone 10 is specifically based on infrared rays (specific standards include IrDA (Infrared Data Association) and IrMC (IrDA Infrared Mobile Communication)). And those using radio waves (specific standards include Bluetooth) are preferably used.

  The data transmission server 30 is a server that transmits various data to the mobile phone 10 by mobile communication. Information to be transmitted includes, for example, information on various services corresponding to the user of the mobile phone 10. Specifically, health management information related to the user of the mobile phone 10, information related to refrigerator inventory management and cooking instruction, news information specialized for the user of the mobile phone 10, and the like correspond to this.

  Subsequently, each function of the mobile phone 10 will be described. As shown in FIG. 1, the mobile phone 10 includes a transmission / reception unit 101, a data storage unit 102, a data amount determination unit 103 (data amount determination unit), a reception cancellation control unit 104 (reception cancellation control unit), a position Information acquisition unit 105 (position information acquisition unit), connection unit 106 (connection unit), request transmission unit 107 (request transmission unit), data transfer unit 108 (data transfer unit), summary reception unit 109 (summary reception) Means).

  The transmission / reception unit 101 is a part that performs transmission / reception of data by mobile communication. The data received by the transmission / reception unit 101 is transmitted to the data storage unit 102.

  The data storage unit 102 is a part that stores data received by the transmission / reception unit 101. The data storage unit 102 has a certain capacity, and cannot store data with a data amount exceeding the capacity.

  The data amount determination unit 103 is a part that acquires information on the data amount of data received by the transmission / reception unit 101 and determines whether or not the data amount exceeds a predetermined value. Specifically, only information relating to the amount of data in the transmitted data is received, and a determination is made by referring to the information. The information related to the amount of data to be acquired is preferably numerical information in units of bytes, for example. Here, the predetermined value is preferably a threshold value for determining whether or not the transmitted data can be received. For example, a specific area having a size of, for example, 1 KB may be provided in the data storage unit 102, and the 1 KB may be set to a predetermined value. Further, the free area of the data storage unit 102 may be set to a predetermined value. When the data amount determination unit 103 determines that the data amount exceeds a predetermined value, information indicating that is transmitted to the reception stop control unit 104.

  The reception stop control unit 104 is a part that controls the transmission / reception unit 101 to stop receiving data when a certain condition is satisfied. The certain conditions will be described later. When reception of data is interrupted, it is preferable to transmit information to that effect to the position information acquisition unit 105 and use it as a trigger for position acquisition by the position information acquisition unit 105.

  The position information acquisition unit 105 is a part that acquires position information of the terminal itself. The acquisition is preferably performed by, for example, acquiring GPS information from a GPS satellite and determining the latitude and longitude of the terminal based on the GPS information. Also, in a mobile communication network, information on a base station that communicates with its own terminal, for example, an ID that identifies the base station is acquired, and the information is used as position information (information about which base station is near). Is preferred. Both of the above two methods are preferably used simultaneously. In that case, latitude, longitude, and information on each base station are used as position information of the terminal itself. Further, even with a method other than the above, for example, when the mobile phone 10 is provided with an RFID (Radio Frequency Identification) tag reader, position information with higher accuracy may be acquired by a system using the RFID tag.

  The connection unit 106 determines whether or not the position of the own terminal specified by the acquired position information satisfies a preset condition, and is connected to the information board 20 by short-range wireless communication based on the determination result. It is the part that controls to establish. Here, it is assumed that the above-described conditions are such that the mobile phone 10 can perform short-range wireless communication with the information board 20. For example, the position information in a state where the connection by the short-range wireless communication is established is acquired in advance, and the condition that the position information acquired by the position information acquisition unit 105 matches the position information acquired in advance is used. It is preferable. In short-distance wireless communication between the mobile phone 10 and the information board 20, a recognition code is registered in advance in each device, and each device is recognized by the recognition code at the time of connection. preferable.

  When the connection unit 106 establishes a connection by short-distance wireless communication, the request transmission unit 107 is a data transmission source, which is a data transmission request that is controlled by the reception cancellation control unit 104 to cancel reception. This is a part to be transmitted to the data transmission server 30. The data to be requested is preferably specified by acquiring information for specifying data when reception is stopped by the reception stop control unit 104, for example.

  The data transfer unit 108 is a part that transfers the data transmitted from the data transmission server 30 in response to the request to the information board 20 through the connection established by the connection unit 106.

  The summary receiving unit 109 is a part that receives summary information of the data included in the transmitted data when the reception stop control unit 104 stops receiving data.

  Note that these functions of the mobile phone 10 are preferably executed by an application program executed by the mobile phone 10. When there are a plurality of data transmission servers 30 that transmit data larger than the storage capacity of the mobile phone 10, the present invention corresponding to the data transmission server 30 is prepared by preparing an application program corresponding to the data transmission server 30. Can be processed.

  Hereinafter, processing executed by the mobile phone 10 according to the present embodiment will be described with reference to the flowchart of FIG. This process is performed when data is transmitted from the data transmission server 30 to the mobile phone 10. For example, in the data providing service as described above, this data transmission is performed as needed according to the service.

  First, the data amount determination unit 103 acquires information regarding the data amount of the transmitted data (S01). Subsequently, the data amount determination unit 103 determines whether or not the data amount exceeds a predetermined value (S02). When it is determined that the data amount does not exceed the predetermined value, the data is received by the transmission / reception unit 101 (S03). The received data is stored in the data storage unit 102.

  When it is determined that the amount of data exceeds a predetermined value, the processing is divided as follows depending on whether or not a connection is established between the mobile phone 10 and the information board 20 (S04). When the connection is established, the data is received and the data is transferred to the information board 20 (S10). When the connection has not been established, the reception cancellation control unit 104 performs control for canceling the reception of data to the transmission / reception unit 101 (S05). When the reception of data is stopped, it is preferable that the summary receiving unit 109 receives summary information of the data included in the transmitted data. By displaying the summary information on the display device of the mobile phone 10, the user can know the outline of the data.

  Subsequently, the position information acquisition unit 105 acquires the position information of the terminal itself (S06). Subsequently, the connection unit 106 determines whether or not the position of the own terminal specified by the acquired position information satisfies the above-described condition (S07). If it is determined that the condition is not satisfied, the position information is acquired again (S06). The acquisition of the position information is preferably performed at a timing such as every 30 minutes or a preset time.

  If it is determined that the condition is satisfied, the connection unit 106 controls to establish a connection with the information board 20 by short-range wireless communication (S08). In order for the user to recognize that the connection has been established, it is preferable to transmit information displayed on the display device of the mobile phone 10 from the information board 20 (for example, contents such as “Return”). When the connection is established by the control, the request transmission unit 107 transmits a request to the data transmission server 30 so that the request transmission unit 107 transmits the data whose reception is stopped in S05 (S09). Subsequently, the data transmitted from the data transmission server 30 in response to the request is received by the transmission / reception unit 101, and the data transfer unit 108 transfers the data to the information board 20 (S10).

  As described above, according to the mobile phone 10 according to the present embodiment, data can be reliably received even when the free capacity of the storage device of the terminal itself is insufficient with respect to the transmitted data. In addition, as in the present embodiment, the position information for establishing the GPS information and the information on the base station can be used to reliably acquire the position information for establishing the short-range wireless communication, and the data can be more reliably obtained. Can be received.
