FIG. 1 is a diagram showing an application example of the wireless communication device 10 according to the present embodiment. The wireless communication device 10 is used in the wireless communication system 1. The wireless communication system 1 includes a ground base station BS, a network N, a push server PS, a terminal information database DB, a communication satellite CS, an aircraft FV, and a wireless terminal device T. Examples of the terminal information database DB include HLR (Home Location Register) and HSS (Home Subscriber Server).

The terrestrial base station BS performs wireless communication with a wireless terminal device T such as a mobile phone or a smartphone. Further, the ground base station BS is connected to the push server PS via the network N.
The terminal information database DB stores information that is referred to when the push server PS pushes and transmits information to the wireless terminal device T.
The push server PS push-transmits information to the wireless terminal device T via the network N or the communication satellite CS based on the information stored in the terminal information database DB. In this example, the push server PS transmits the ground station transmission wave WT1 to the communication satellite CS.
Further, the push server PS receives the ground station reception wave WR3 from the communication satellite CS.
The communication satellite CS transfers the communication wave transmitted by the push server PS. Further, the communication satellite CS transfers the received communication wave to the push server PS. In this example, the communication satellite CS receives the ground station transmission wave WT1 and transfers it to the aircraft FV as the ground station transmission wave WT2. Further, the communication satellite CS receives the ground station received wave WR2 from the aircraft FV and transfers it to the push server PS as the ground station received wave WR3.
The aircraft FV transfers the communication wave transmitted by the push server PS via the communication satellite CS. Further, the aircraft FV transfers the received communication wave to the communication satellite CS. The aircraft FV stays above the destination DST, covers the destination DST, and communicates with the wireless terminal device T in the destination DST. In this example, the aircraft FV receives the ground station transmission wave WT2 from the communication satellite CS and transfers it to the wireless terminal device T as the ground station transmission wave WT3. Further, the aircraft FV receives the ground station reception wave WR1 from the wireless terminal device T and transfers it to the communication satellite CS as the ground station reception wave WR2.

If communication between the aircraft FV and the ground base station BS is possible, the aircraft FV may communicate with the ground base station BS instead of the communication satellite CS. In this case, the aircraft FV receives the ground station transmission wave WT4 and transfers it to the wireless terminal device T as the ground station transmission wave WT3. Further, the aircraft FV receives the ground station reception wave WR1 from the wireless terminal device T and transfers it to the ground base station BS as the ground station reception wave WR4.

An example of a destination DST is an isolated area where wireless communication services are not provided. An isolated area is an area in which a wireless communication service cannot be used due to a failure of a wireless base station on the ground due to, for example, a disaster. In such an area, communication for confirming the safety and grasping the location becomes impossible, and the convenience of the user of the wireless communication service is reduced. Aircraft FVs stay over such isolated areas to provide wireless communications services.

The destination DST is not limited to the isolated area created by the disaster. The destination DST may be, for example, an event venue in the mountains where wireless communication services are not provided.

By the way, the number of aircraft FVs that can be dispatched to the destination DST may be limited. Moreover, even if the aircraft FV can be dispatched to the destination DST, the flight time may be limited. In such a case, it is difficult to continue to provide the wireless communication service to the destination DST. For example, when the fuel of the aircraft FV is low, it must be returned from the destination DST to the flight base FB. Then, at the destination DST, the user cannot use the wireless communication service.

In such a case, the user in the destination DST must communicate while the aircraft FV is staying above the destination DST. In this case, if the user can know the staying time of the aircraft FV, he / she can communicate with a margin. Further, if the user can know the next visit schedule of the aircraft FV, it is possible to reduce the occurrence of unnecessary and unurgent communication and prevent the communication line from being congested.

The registration request RR may be automatically transmitted regardless of the user's operation when the power of the wireless terminal device T is turned on or when a handover occurs.

Returning to FIG. 5, the registration request acquisition unit 150 of the wireless communication device 10 receives the registration request RR from the wireless terminal device T (step S10).
The registration request transfer unit 160 transfers the registration request RR received by the registration request acquisition unit 150 to the communication satellite CS (step S20). At this time, the registration request transfer unit 160 attaches the area information indicating the position of the area where the own aircraft FV stays to the registration request RR and transmits it to the communication satellite CS.
When the communication satellite CS receives the registration request RR from the wireless communication device 10, the communication satellite CS transfers the received registration request RR to the push server PS. The push server PS stores the received registration request RR in the terminal information database DB as wireless terminal information TI. Specifically, when the push server PS receives the registration request RR from the wireless terminal device T1 of the wireless terminal device T, the push server PS associates the terminal ID included in the registration request RR with the area information and terminals the terminal. Stored as wireless terminal information TI in the information database DB.

[Modification 1]
Although the case where the wireless communication device 10 is provided in the aircraft FV in the wireless communication system 1 has been described so far, the present invention is not limited to this.
FIG. 9 is a diagram showing a first modification of the wireless communication system 1 of the present embodiment.

For example, when the destination DST in the coastal area becomes a communication isolated area due to a tsunami disaster or the like, the ship SP may provide a wireless communication service instead of the aircraft FV or together with the aircraft FV. If it is a ship SP, the staying time in the vicinity of the destination DST can be extended as compared with the aircraft FV.

[Modification 2]
In the wireless communication system 1, the case where communication is relayed by one aircraft FV has been described so far, but the present invention is not limited to this.
FIG. 10 is a diagram showing a second modification of the wireless communication system 1 of the present embodiment. As shown in the figure, the wireless communication system 1 may provide a wireless communication service to the destination DST by sequentially relaying communication by a plurality of aircraft FVs. According to the wireless communication system 1 configured in this way, the wireless communication service can be provided to the destination DST without going through the communication satellite CS. Communication via the communication satellite CS may have a small communication capacity or a high communication cost. By linking a plurality of aircraft FVs, it is possible to provide a large-capacity communication line and reduce communication costs as compared with the case of passing through the communication satellite CS.

[Modification 3]
In the wireless communication system 1, the case where the wireless terminal device T and the network N are connected in real time by communication between the aircraft FV and the communication satellite CS has been described, but the present invention is not limited to this. Here, for text information such as e-mail, it may not always be required to make a line connection between the wireless terminal device T and the network N in real time. For example, even if several hours have elapsed from the transmission of text information such as e-mail from the wireless terminal device T to the transmission to the network N, it may be acceptable. In such a case, the wireless communication system 1 can be configured as follows.

That is, as shown in FIG. 2, the aircraft FV may pass through an area (communicable area CA) capable of communicating with the ground base station BS depending on its flight route. In this case, the wireless communication device 10 of the aircraft FV stores the communication content with the wireless terminal device T in the communication content storage unit 170. When the aircraft FV passes through the communicable area CA, the wireless communication device 10 transfers the information stored in the communication content storage unit 170 to the ground base station BS. Further, the wireless communication device 10 may transmit the information stored in the communication content storage unit 170 to the wireless terminal device T in the destination DST when staying at the destination DST. According to the wireless communication system 1 configured in this way, the wireless communication service can be provided to the destination DST without going through the communication satellite CS.
Further, when the wireless communication device 10 cannot communicate with the communication satellite CS or the ground base station BS, the wireless communication device 10 may control whether or not communication is possible according to the type of communication means. The types of communication means include those that require real-time communication (for example, telephone) and those that do not require real-time communication (for example, e-mail). Specifically, the wireless communication device 10 may prohibit the use of the telephone when communication with the communication satellite CS or the ground base station BS is not possible. Further, the wireless communication device 10 is configured to allow the use of e-mail and store the e-mail information in the communication content storage unit 170 when communication with the communication satellite CS or the ground base station BS is not possible. You may.
Further, the communication means referred to here includes various applications operating in the wireless terminal device T. Types of this application include those that send and receive large amounts of information and those that send and receive relatively small amounts of information. The wireless communication device 10 may control whether or not communication is possible based on the amount of information. For example, the wireless communication device 10 may prohibit the use of an application that transmits and receives a large amount of information. In this case, the wireless communication device 10 may control the availability of the application by transmitting information for controlling the use of the specific application to the wireless terminal device T.

[Modification example 4]
In the wireless communication system 1, the case where the wireless communication device 10 communicates with each wireless terminal device T in the destination DST has been described so far, but the present invention is not limited to this. The wireless communication device 10 may divide a plurality of wireless terminal devices T in the destination DST into groups and perform communication. For example, when the staying time of the aircraft FV at the destination DST is 60 minutes, the wireless communication device 10 has a first group in which the own station number (for example, a telephone number) of the wireless terminal device T is an odd number and an even number. Communication may be performed by dividing into two groups. In this case, the wireless communication device 10 may allocate the first 30 minutes of the 60 minutes to the communication with the first group and the remaining 30 minutes to the communication with the second group. According to the wireless communication system 1 configured in this way, wireless communication is performed while avoiding line congestion even when the number of lines that can be provided is relatively small with respect to the number of wireless terminal devices T in the destination DST. Can provide services.

[Modification 5]
For example, a close relative of the missing person reports the missing person to the police, and the police inquires of the telecommunications carrier to identify the subscriber ID of the missing person. The subscriber ID may be specified based on the subscriber information obtained from the publicly available DB of the missing person.
Further, in the server of network N (not shown), a wearable terminal such as a wristwatch with a wireless function linked to the current time and the subscriber ID is used as a base station from the database (HLR / HSS) based on the subscriber ID. The connection time, the position information of the terminal, and the biometric information (pulse, surface skin temperature, etc.) of the subscriber are acquired. If the location information is not updated even after the lapse of a predetermined time, it is determined that the subscriber cannot connect to the base station. The biometric information of the subscriber may be detected by a sensor provided in the terminal.
Further, when the number of subscribers counted by the server of network N exceeds a predetermined number and the latest position information of a plurality of subscribers acquired by the server is within a predetermined range, the predetermined number is specified. Determine that the area is an isolated area. If there are multiple isolated areas, the server may prioritize (for rescue) based on the number of subscribers, biometric information, etc. included in the isolated areas. According to the wireless communication system 1 configured in this way, it is possible to search for a missing person even in an isolated area.
