<Operation example of embodiment>
Next, an example of the operation of this embodiment will be described. First, the administrator of the digital photo frame 10A operates the terminal device 50A to send an e-mail attached with image data with the e-mail address of the digital photo frame 10A as a destination (FIG. 10: step S1). The communication unit 405 of the photo server 40 receives the transmitted electronic mail. When the photo server 40 receives the e-mail, the photo server 40 executes processing for transferring image data and text information extracted from the received e-mail.

  Specifically, the control unit 401 of the photo server 40 executes the process shown in FIG. The control unit 401 searches the “administrator address” field and the “participant address” field of the user database DB1 for the e-mail address of the sender of the received e-mail. Here, for example, when the sender's email address is “ccc@xxx.com”, because the sender's email address is in the “manager address” field (YES in step SA1), FIG. The record in the first line is searched. If the sender's e-mail address is not found in the “administrator address” field and the “participant address” field (NO in step SA1), the control unit 401 ends the transfer processing of the image data and text information. .

  If the determination is YES in step SA1, the control unit 401 determines whether there is an e-mail address that is the destination of the received e-mail in the “photo frame address” field of the retrieved record. Here, for example, when the e-mail address of the received e-mail is “aaa@xxx.com”, in the retrieved record on the first line in FIG. Since “aaa@xxx.com” is stored, the control unit 401 determines that the e-mail address that is the destination of the received e-mail is in the “photo frame address” field of the retrieved record. Judgment is made (YES in step SA2). If there is no e-mail address that is the destination of the received e-mail in the “photo frame address” field of the retrieved record (NO in step SA2), the control unit 401 stores the image data and text information. End the transfer process.

  If YES in step SA2, the control unit 401 transfers the image data and text information extracted from the received e-mail to the digital photo frame 10A specified by the e-mail address that is the destination of the e-mail. (Step SA3, Step S2). The communication unit 105 of the digital photo frame 10A receives image data and text information transmitted from the photo server 40.

Next, when an emergency earthquake bulletin, which is an example of emergency information, is distributed from the Japan Meteorological Agency, the communication unit 305 of the emergency information server 30 receives the distributed emergency earthquake bulletin (step S4). The earthquake early warning includes an earthquake occurrence time, an epicenter, an area name having a predicted seismic intensity of 4 or more, and the like. In this operation example, the operation will be described by taking the case where the emergency information is an emergency earthquake bulletin as an example. However, the emergency information is not limited to the emergency earthquake bulletin, but can be a tsunami warning or disaster / evacuation information. There may be.
The control unit 301 of the emergency information server 30 generates a message to be displayed on the digital photo frame 10 and the terminal device 50 based on the received emergency information. Moreover, the control part 301 determines the delivery area which delivers emergency information based on the area name contained in emergency information. The control unit 301 transmits the generated message to the wireless network control device that covers the determined distribution area among the wireless network control devices included in the communication network 20. The radio network controller that has received the message sends the received message to the radio base station. The wireless base station distributes the message sent from the wireless network control device (step S5). For example, when the digital photo frame 10B and the terminal device 50A are in the area of the area name included in the earthquake early warning, the message generated from the earthquake early warning is delivered to these devices. When the digital photo frame 10A and the terminal device 50B are not located in the area of the area name included in the earthquake early warning, the message generated from the earthquake early warning is sent to the digital photo frame 10A and the terminal device 50B. Will not be delivered.

  When the terminal device 50A and the digital photo frame 10B are not communicating via the communication network 20, the terminal device 50A and the digital photo frame 10B receive the message distributed from the radio base station (steps S6 and S7). The terminal device 50A and the digital photo frame 10B display the received message (steps S8 and S9). In the digital photo frame 10B, the emergency information acquisition unit 152 acquires a message and generates an image of the message, and the display control unit 153 controls the display unit 104 so that the image of the message is displayed. An example of the displayed message is shown in FIG.

On the other hand, after transmitting the message generated from the emergency information, the emergency information server 30 communicates the position information of the terminal device 50 located in the distribution area where the emergency information is distributed and the terminal identification information of the terminal device 50. Obtained from the location register of the network 20 (step S10).
Specifically, the emergency information server 30 transmits distribution area information representing the determined distribution area to the location register. The location register receives the distribution area information transmitted from the emergency information server 30. The location register specifies a radio base station that covers the area represented by the distribution area information. For each identified radio base station, the location register sets the location information of the radio base station and the terminal identification information of the terminal device 50 located in the area covered by the radio base station to the emergency information server 30. Send. In the present embodiment, the electronic mail address of the user of the terminal device 50 is used as the terminal identification information.

  For example, as shown in FIG. 11, when the terminal device 50A is located in a communication area covered by the radio base station 21A and the terminal device 50B is located in a communication area covered by the radio base station 21B, the radio base station A set of 21A position information (for example, latitude and longitude information) and terminal identification information of the terminal device 50A is transmitted from the location register to the emergency information server 30, and the position information of the radio base station 21B and the terminal identification of the terminal device 50B are transmitted. A set of information is transmitted from the location register to the emergency information server 30. Since the terminal device 50 is within a predetermined range from the radio base station when located in the communication area of the radio base station, the location information of the radio base station and the location information of the terminal device 50 are used. Can be considered.

  The emergency information server 30 transmits the set of terminal identification information and position information transmitted from the location register and the emergency information received in step S4 to the photo server 40 (step S11). The photo server 40 receives the transmitted set of terminal identification information and position information and emergency information (step S12). When receiving various information, the control unit 401 executes processing for generating image data to be transmitted to the digital photo frame 10 (step S13).

  Specifically, the control unit 401 executes the process shown in FIG. First, the control unit 401 searches the “manager address” field and the “participant address” field of the user database DB1 for the received terminal identification information. Here, when the received terminal identification information is stored in the “administrator address” field or “participant address” field of the user database DB1 (YES in step SB1), the control unit 401 searches the terminal identification information retrieved. The information of the evacuation site associated with the position information received in pairs is acquired from the evacuation site database DB2 (step SB2). Based on the acquired evacuation site, the control unit 401 generates an image of the evacuation site and a map around the evacuation site from the map data stored in the storage unit 402 (step SB3). In addition, the control unit 401 generates a text to be displayed on the digital photo frame 10 using the received emergency information, the acquired evacuation place, the acquired position information, and the like (step SB4).

  The control unit 401 generates image data representing the text generated in step SB4 and the map generated in step SB3 (step SB5). In addition, the control unit 401 extracts the email address stored in the “photo frame address” field of the record in which the searched terminal identification information is stored, and extracts the destination of the image data generated in step SB5. The digital photo frame 10 specified by the e-mail address is transmitted (step SB6, step S14).

  For example, as described above, when the terminal device 50A is located in the area of the area name included in the earthquake early warning, the emergency information server 30 sends the email address “ccc @ of the user of the terminal device 50A. XX.com "and the location information of the radio base station 21A covering the area where the terminal device 50A is located are transmitted. When the control unit 401 searches for “ccc@xxx.com” in the user database DB1, one line of “ccc@xxx.com” of the received terminal identification information is stored in the user database DB1 of FIG. Since it is in the “manager address” field of the first record, the record in the first line is searched.

  Next, the control unit 401 acquires, from the evacuation site database DB2, information on the evacuation site associated with the position information received in combination with “ccc@xxx.com” of the searched terminal identification information. Here, for example, when the received position information is “N: ΔΔ.xxx, E: ○○○. □ Δx”, this position information is one line in the evacuation site database DB2 of FIG. Stored in the eye record. The control unit 401 acquires the information “◯ × Gymnasium” stored in the record in the first row from the evacuation site database DB2. When the control unit 401 acquires the evacuation site information, the control unit 401 generates an image of the acquired “◯ × Gymnasium” and a map of the vicinity of “○ × Gymnasium” from the map data stored in the storage unit 402.

  In addition, the control unit 401 generates text to be displayed on the digital photo frame 10 using the received emergency information, position information, acquired evacuation site, and the like. Here, since the emergency information transmitted from the emergency information server 30 is an earthquake early warning, this sentence includes the date and time of occurrence of the earthquake, the location of the earthquake, the received location information, and the user of the received terminal identification information. Includes text to inform you of the location of the earthquake and evacuation site. The control unit 401 generates image data of an image including the generated text image and map image. The control unit 401 stores the generated image data in the “photo frame address” field of the record storing the terminal identification information “ccc@xxx.com” retrieved in step SB1. It is transmitted to the digital photo frame 10 specified by the electronic mail address “aaa@xxx.com”.
