Description

携帯電話端末を利用した地域情報システムRegional information system using mobile phone terminals
　本発明は、電気通信事業者が提供する公衆通信回線網（電話網、データ網）に無線接続可能な携帯電話端末を利用して、特定の地域内において情報を受発信する地域情報システムに関する。 The present invention relates to a regional information system that receives and transmits information in a specific region using a mobile phone terminal that can be wirelessly connected to a public communication line network (telephone network, data network) provided by a telecommunications carrier.
　地震や洪水等の大規模な災害が発生した場合において、地域住民に対して緊急情報（災害情報や避難指示等）を報知するためのシステムとして、地域住民への緊急情報を防災無線基地局から屋外子機や各民家に設置した戸別受信機を通して文字表示又は音声で通知する地域防災無線システムが知られている。 As a system for notifying local residents of emergency information (disaster information, evacuation instructions, etc.) in the event of a large-scale disaster such as an earthquake or flood, emergency information for local residents is sent from the disaster prevention radio base station. 2. Description of the Related Art A local disaster prevention wireless system is known in which characters are displayed or voiced through an outdoor cordless handset or a door-to-door receiver installed in each private house.
　この地域防災無線システムでは、放送された音声が届かない又は届きにくい場所にいる人、また、地域防災無線システムの受信機のない場所にいる人には、緊急情報を伝達することが困難である等、緊急情報を通知する地域内であっても地域住民の所在位置や、周囲の環境条件によって情報伝達が妨げられてしまう場合がある。この問題の解決を試みる技術として、防災無線システムによる報知に加えて、緊急情報を公衆通信回線網（携帯電話網）を介して地域内の携帯電話端末にも送るようにして、情報伝達の確実性を高めるようにしたものが提案されている（特許文献１を参照）。 In this regional disaster prevention radio system, it is difficult to transmit emergency information to people who are in a place where the broadcast sound does not reach or is difficult to reach, or to people who are not in a location where there is no receiver of the regional disaster prevention radio system. Even in the area where emergency information is notified, information transmission may be hindered by the location of local residents and the surrounding environmental conditions. As a technology to try to solve this problem, in addition to notification by the disaster prevention radio system, emergency information is also sent to mobile phone terminals in the area via the public communication network (mobile phone network) to ensure information transmission. The thing which improved the property is proposed (refer patent document 1).

That is, when a signal (drive signal) transmitted from the regional wireless transmission center is received in the regional wireless operating layer, a program (forced control program) forcibly controlling the wireless control program in the operating system layer is executed, and WiFi is executed. The local wireless network connection registered in the settings (connection to the local wireless LAN access point 15) is prioritized. This forced control program is stored in the memory (FRAM) of the IC chip 21b.
　次に、この地域防災無線システム１の動作について、説明する。図６は本発明の実施形態の初期設定時の動作及び手続を示すフローチャートである。まず、この地域防災無線システム１の管轄地域内において、本システム１に利用すべき一般の携帯電話端末（スマートフォン）２の電池パック収容部３５から標準電池パックを取り出し、これに代えて、特殊電池パック２１を電池パック収容部３５に装着する（ステップＳ１１）。 Next, the operation of the regional disaster prevention radio system 1 will be described. FIG. 6 is a flowchart showing operations and procedures at the time of initial setting according to the embodiment of the present invention. First, in the jurisdiction area of the regional disaster prevention radio system 1, a standard battery pack is taken out from the battery pack housing portion 35 of a general mobile phone terminal (smart phone) 2 to be used for the system 1, and a special battery is used instead. The pack 21 is attached to the battery pack housing part 35 (step S11).
　次いで、携帯電話端末２の電源をオンにし（ステップＳ１２）、携帯電話端末２の標準オペレーティングシステムによって提供されるＷｉＦｉ設定（アプリケーション）を起動して、これに伴い表示されるＷｉＦｉ画面において、ＷｉＦｉ接続をオンにすると（ステップＳ１３）、通信可能な無線ＬＡＮアクセスポイント（標準無線ＬＡＮアクセスポイント４ａ、地域無線ＬＡＮアクセスポイント１５を含む）のアドレス設定が自動取得される（ステップＳ１４）。次いで、ＷｉＦｉ接続可能なアクセスポイントの識別情報が表示されるので、その中から地域無線ＬＡＮアクセスポイント１５を示す識別情報を選択する（ステップＳ１５）。次いで、これに続いて表示されるＰＷ（パスワード）入力欄に事前に付与されているパスワード入力する。 Next, the mobile phone terminal 2 is turned on (step S12), the WiFi setting (application) provided by the standard operating system of the mobile phone terminal 2 is activated, and the WiFi connection is displayed on the WiFi screen displayed accordingly. When is turned on (step S13), the address settings of communicable wireless LAN access points (including the standard wireless LAN access point 4a and the regional wireless LAN access point 15) are automatically acquired (step S14). Next, since the identification information of the access point capable of WiFi connection is displayed, the identification information indicating the regional wireless LAN access point 15 is selected from the identification information (step S15). Next, a password assigned in advance is entered in a PW (password) input field that is displayed subsequently.

In addition, the address setting of the regional wireless LAN access point 15 is different when moving to a region where the same system as the regional disaster prevention radio system 1 is installed outside the area controlled by the regional disaster prevention radio system 1 Therefore, the initial setting is similarly performed in the destination area (steps S12 to S16 in FIG. 6). The initial setting may be performed once in each area. That is, if the user enters again after going out of the area where the initial setting has been performed, the address setting is retained, so there is no need to perform the initial setting.
　図７は本地域防災無線システム１の災害発生時（緊急時）の動作を示すフローチャートである。災害が発生し、地域情報発信センター１１において、地域住民に災害状況や避難指示等の緊急度の高い緊急情報を報知する必要がある場合には、地域無線送信センター１１から、強制切替制御を開始すべきことを示す制御信号として緊急駆動信号（情報発信駆動信号）が送信される。この緊急駆動信号は地域無線ＢＡＳ基地局１２及び地域無線ＢＡＳ中継局１３を介して、固定側制御信号送受信手段１４に送られ、該固定側制御信号送受信手段１４から無線送信される。 FIG. 7 is a flowchart showing the operation of the local disaster prevention radio system 1 when a disaster occurs (emergency). When a disaster occurs and the local information transmission center 11 needs to notify the local residents of emergency information with a high degree of urgency, such as a disaster situation or an evacuation instruction, the local wireless transmission center 11 starts forced switching control.

Even if the forced switching signal is transmitted (step S22) and the determination of whether the switching process is correct (step S23) is repeated a predetermined number of times (here, 10 times as an example), it is determined as failure (NG). If it is (NO), the process proceeds to step S27, where the mobile phone state is maintained, that is, the control based on the standard operating system by the standard control means 31 is continued.
　ステップＳ２３において、切替処理が成功（ＯＫ）したと判断された場合（Ｙｅｓの場合）には、標準オペレーティングシステムが提供するＷｉＦｉ設定における接続先アクセスポイントを初期設定で登録した地域無線ＬＡＮアクセスポイント１５に強制的に変更する。これにより、携帯電話端末２は無線ＬＡＮ手段３４、地域無線ＬＡＮアクセスポイント１５、地域無線中継局１３及び地域無線ＢＡＳ基地局１２を介して、地域無線送信センター１１と通信可能（地域情報開通）となり、このリンク（接続経路）を介して、地域無線送信センター１１から緊急情報が携帯電話端末２に送られ、ＬＣＤ画面３２に表示される（ステップＳ２４）。 If it is determined in step S23 that the switching process has succeeded (OK) (in the case of Yes), the local wireless LAN access point 15 in which the connection destination access point in the WiFi setting provided by the standard operating system is registered as the initial setting.

The emergency information is sent from the regional radio transmission center 11 to the mobile phone terminal 2 via this link (connection route) and displayed on the LCD screen 32 (step S24).
　次いで、強制制御手段２２は、緊急駆動信号の解除信号を受信した否かを判断しており（ステップＳ２５）、該解除信号を受信したと判断した場合（Ｙｅｓの場合）には、強制制御手段２２は標準制御手段３１に地域無線送信センター１１からの情報発信が終了したことをＬＣＤ画面３２に表示させて（ステップＳ２６）、携帯電話状態、即ち標準制御手段３１による標準オペレーティングシステムに基づく制御に戻る（ステップＳ２７）。 Next, the forcible control means 22 determines whether or not an emergency drive signal cancel signal has been received (step S25). If it is determined that the cancel signal has been received (in the case of Yes), the forcible control means 22 22 causes the standard control means 31 to display on the LCD screen 32 that the information transmission from the regional radio transmission center 11 has been completed (step S26), so that the mobile phone status, that is, control based on the standard operating system by the standard control means 31 is performed.

If it is determined to be unsuccessful (NG) (NO), the process returns to step S32, and the forced switching signal is transmitted again. To do. Even if the forced switching signal is transmitted (step S32) and the determination of whether the switching process is correct (step S33) is repeated a predetermined number of times (here, 10 times as an example), it is determined as failure (NG). If YES (NO), the process proceeds to step S39, where the mobile phone state is maintained, that is, the control based on the standard operating system by the standard control means 31 is continued.
　ステップＳ３３において、切替処理が成功（ＯＫ）したと判断された場合（Ｙｅｓの場合）には、強制制御手段２２は標準制御手段３１を制御して、地域情報が着信したことを示す表示（着信表示）及び該地域情報の表示を許可するか否かを選択するための画面表示をＬＣＤ画面３２に表示する（ステップＳ３４）。 In step S33, when it is determined that the switching process is successful (OK) (in the case of Yes), the forced control unit 22 controls the standard control unit 31 to display that the area information has been received (incoming call). Display) and a screen display for selecting whether or not to permit display of the area information is displayed on the LCD screen 32 (step S34).

Even if the forced switching signal is transmitted (step S42) and the determination of whether the switching process is correct (step S43) is repeated a predetermined number of times (here, 10 times as an example), a failure (NG) is determined. If YES (NO), the process proceeds to step S48, and the mobile phone state is maintained, that is, the control based on the standard operating system by the standard control means 31 is continued.
　ステップＳ４３において、切替処理が成功（ＯＫ）したと判断された場合（Ｙｅｓの場合）には、強制制御手段２２は標準制御手段３１を制御して、地域情報が着信したことを示す表示（着信表示）及び該地域情報の表示を許可するか否かを選択する画面表示をＬＣＤ画面３２に行う（ステップＳ４４）。 In step S43, when it is determined that the switching process is successful (OK) (in the case of Yes), the forced control unit 22 controls the standard control unit 31 to display that the area information has been received (incoming call). Display) and a screen display for selecting whether or not to permit display of the area information is displayed on the LCD screen 32 (step S44).
　次いで、ユーザーによりタッチパネル３３を介して入力された選択内容が許可であるか、不可であるかを判断し（ステップＳ４５）、許可であると判断した場合（Ｙｅｓの場合）には、標準オペレーティングシステムが提供するＷｉＦｉ設定における接続先アクセスポイントを初期設定で登録した地域無線ＬＡＮアクセスポイント１５に強制的に変更する。これにより、携帯電話端末２は無線ＬＡＮ手段３４、地域無線ＬＡＮアクセスポイント１５、地域無線ＢＡＳ中継局１３及び地域無線ＢＡＳ基地局１２を介して、地域無線送信センター１１と通信可能（地域情報開通）となり、このリンク（接続経路）を介して、地域無線送信センター１１から通常情報が携帯電話端末２に送られ、ＬＣＤ画面３２に表示される（ステップＳ４６）。ステップＳ４５において、不可が選択されたと判断した場合（ＮＯの場合）には、携帯電話状態、即ち標準制御手段３１による標準オペレーティングシステムに基づく制御に戻る（ステップＳ４８）。 Next, it is determined whether the selection content input by the user via the touch panel 33 is permitted or not (step S45). If it is determined that the selection is permitted (Yes), the standard operating system is selected. The connection destination access point in the WiFi setting provided by is forcibly changed to the local wireless LAN access point 15 registered in the initial setting. Thereby, the cellular phone terminal 2 can communicate with the regional wireless transmission center 11 via the wireless LAN means 34, the regional wireless LAN access point 15, the regional wireless BAS relay station 13, and the regional wireless BAS base station 12 (regional information opening). Through this link (connection route), normal information is sent from the regional wireless transmission center 11 to the mobile phone terminal 2 and displayed on the LCD screen 32 (step S46). If it is determined in step S45 that disabling has been selected (in the case of NO), the mobile phone state, that is, control based on the standard operating system by the standard control means 31 is returned (step S48).
　通常情報をＬＣＤ画面３２に表示した後、強制制御手段２２は、通常駆動信号の解除信号の受信を待つことなく、強制制御手段２２は標準制御手段３１に地域防災無線システム１からの情報発信が終了したことをＬＣＤ画面３２に表示させて（ステップＳ４７）、携帯電話状態、即ち標準制御手段３１による標準オペレーティングシステムに基づく制御に戻る（ステップＳ４８）。 After the normal information is displayed on the LCD screen 32, the forcible control unit 22 does not wait for the reception of the release signal of the normal drive signal, and the forcible control unit 22 sends the information from the regional disaster prevention radio system 1 to the standard control unit 31. The completion is displayed on the LCD screen 32 (step S47), and the mobile phone status, that is, the control based on the standard operating system by the standard control means 31 is returned (step S48).
　図７及び図８に示したフローチャートでは、地域無線送信センター１１から緊急駆動信号又は通常駆動信号（継続接続）が発信され、携帯電話端末２において、強制切替制御が行われて、地域無線ＬＡＮアクセスポイント１５を介したリンクが確立されている場合には、地域無線送信センター１１から解除信号が発信されて、強制切替制御が終了するまでは、原則として、その状態が維持される。即ち、携帯電話端末２は、地域無線送信センター１１による管理下（制御下）に置かれることになり、この状態では、携帯電話端末２の通常の通話機能やアプリケーションを含むサービスの一部又は全部の利用が制限されることになる。しかし、地域防災無線システム１の管理下に置かれている場合であっても、これを解除して、これらのサービスを利用したい場合もある。そこで、本実施形態では、強制制御手段２２により強制切替制御が実行されている場合であっても、携帯電話端末２において無線ＬＡＮ手段３４による無線ＬＡＮ接続をオフにするための操作（ＷｉＦｉ設定をオフにする操作）が行われた場合には、強制制御手段２２は強制切替制御を終了するようにしている。 In the flowcharts shown in FIGS. 7 and 8, an emergency drive signal or a normal drive signal (continuous connection) is transmitted from the regional wireless transmission center 11, and forced switching control is performed in the mobile phone terminal 2 to access the local wireless LAN. When the link via the point 15 is established, the state is maintained in principle until a release signal is transmitted from the regional radio transmission center 11 and the forced switching control is terminated. That is, the mobile phone terminal 2 is placed under the control (control) of the regional wireless transmission center 11, and in this state, part or all of the services including the normal call function and application of the mobile phone terminal 2 Will be restricted. However, even if it is under the control of the regional disaster prevention radio system 1, it may be desired to cancel this and use these services. Therefore, in the present embodiment, even when the forced switching control is being executed by the forced control means 22, an operation (WiFi setting is performed for turning off the wireless LAN connection by the wireless LAN means 34 in the mobile phone terminal 2. When the operation to turn off is performed, the forcible control means 22 ends the forcible switching control.
　上述した実施形態によると、既存の携帯電話端末（スマートフォン）２の電池パック（標準電池パック）を特殊電池パック２１と交換して装着するだけで、本防災無線システムを導入している地域の何処にいても、地域無線送信センター１１からの緊急情報等を受け取ることができる。携帯電話会社としての通信事業者が提供する携帯電話端末２は、高い水準で普及しており、近時では誰でも所持しているものであるから、地域防災無線システムを利用するために、専用の端末を個別に配布する場合と比較して、全体のコストを低減することができる。 According to the above-described embodiment, by replacing the battery pack (standard battery pack) of the existing mobile phone terminal (smart phone) 2 with the special battery pack 21 and installing the disaster prevention radio system, Even in this case, it is possible to receive emergency information from the regional radio transmission center 11. The mobile phone terminal 2 provided by a telecommunications carrier as a mobile phone company is prevailing at a high level and is owned by anyone recently, so it is dedicated to use the regional disaster prevention radio system. Compared with the case where each terminal is distributed individually, the overall cost can be reduced.
