Description

Translated fromJapanese

本発明は、複数の携帯端末と、電波の合理的利用から設定された地理的エリア内の携帯電話制御局または携帯電話交換機と、携帯電話制御局または携帯電話交換機に接続された緊急警報を発する緊急警報発信源により構成される携帯電話システムであって、複数の携帯端末に対して緊急警報を一斉即時送信できる携帯電話システムに関する。  The present invention issues a plurality of mobile terminals, a mobile phone control station or mobile phone switch in a geographical area set based on rational use of radio waves, and an emergency alert connected to the mobile phone control station or mobile phone switch. The present invention relates to a mobile phone system configured by an emergency alert transmission source and capable of transmitting emergency alerts simultaneously to a plurality of mobile terminals simultaneously.

携帯端末に対する緊急性の高い情報の伝達手段として、情報提供者が予め登録された携帯端末の利用者に対して、登録された電話番号を個々に呼び出して電子メールなどの形で情報を送信する方法があるが、この方法では、複数の携帯端末利用者に対して情報を順次送信しなければならず、相手先がN人であれば一人に送信する時間のN倍の時間を、通信事業者が持っている割り当てられた周波数に由来する固有のトラヒック量で除した時間を要する。したがって、この方法は、緊急を要する伝達情報、例えば地震の到来を数秒〜数十秒前に予測可能なP波を検出して警報を発する緊急地震速報など即時的に受信できなければその価値が失われてしまうような用途には使用できない。  As a means of transmitting highly urgent information to a mobile terminal, an information provider individually calls a registered telephone number and transmits the information in the form of an e-mail or the like to a mobile terminal user registered in advance. There is a method, but in this method, information must be sequentially transmitted to a plurality of mobile terminal users, and if the other party is N people, N times as long as the time to transmit to one person It takes time divided by the specific traffic volume derived from the assigned frequency that the person has. Therefore, this method is valuable if it cannot be received immediately such as emergency information such as emergency information that detects warnings by detecting P-waves that can predict the arrival of an earthquake several seconds to several tens of seconds before the arrival of an earthquake. It cannot be used for purposes that would be lost.

このような問題を解決する従来移動通信における複数のエリア内に存在する複数の携帯端末に対する同報通信システムとして、複数の移動通信端末と、各エリア毎に存在しそのエリア内に在圏する移動通信端末と通信する無線基地局と、該無線基地局に接続され一般公衆通信網等からの移動通信呼の交換を行う移動通信交換機と、移動通信端末の情報を用い移動通信交換機に接続される端末情報データベースとから構成される移動通信システムにおいて、前記端末情報データベースに各移動通信端末の同報グループ識別情報、位置情報、接続優先順位を記憶し、前記移動通信交換機は、マルチミキシングする手段を有し、前記端末情報データベースに問い合わせて得た情報を用いて各エリア毎に在圏する同報グループの優先順位の高い移動通信端末を代表端末として呼び出し、各エリアの接続した代表端末をマルチミキシング接続することが提案されている(例えば、特許文献1参照)。  As a broadcast communication system for a plurality of mobile terminals existing in a plurality of areas in conventional mobile communication that solves such a problem, a plurality of mobile communication terminals and a movement that exists in each area and exists in that area A radio base station that communicates with a communication terminal, a mobile communication exchange that is connected to the radio base station and exchanges a mobile communication call from a general public communication network, and the like, and is connected to the mobile communication exchange using information on the mobile communication terminal In the mobile communication system composed of a terminal information database, broadcast terminal group identification information, location information, and connection priority of each mobile communication terminal are stored in the terminal information database, and the mobile communication switch includes means for multi-mixing And using the information obtained by making an inquiry to the terminal information database, the high-priority mobile network of each broadcast group located in each area. Call the terminal as a representative terminal, the representative terminal connected for each area to be multi-mixing connected has been proposed (e.g., see Patent Document 1).

このシステムでは、予め同報の対象となる複数の移動通信端末をグループとして登録するとともに、そのグループのそれぞれの端末がどのエリアにいるかを判別してそれぞれのエリアに在圏する移動体通信端末の代表端末に対して通信し、この通信を他の移動通信端末が傍受するという構成をとっており、グループに登録された停滞通信端末に対してのみ同報することが可能となる。  In this system, a plurality of mobile communication terminals to be broadcasted are registered as a group in advance, and the area of each group of mobile communication terminals is determined by determining which area each terminal of the group is in. The communication is made with the representative terminal, and this communication is intercepted by other mobile communication terminals, and it is possible to broadcast only to the stagnant communication terminals registered in the group.

また、特定の利用者グループに対し予め設定された周波数を用い同時送信用の無線端末を使用して音声も含めた情報を同時に送信する方法、すなわち、複数の携帯電話と、携帯電話の携帯用交換局と、携帯用交換局と接続された各種情報プロバイダとにより構成され、前記複数の携帯電話と前記携帯用交換局とに同時送信用の送信先情報を登録しておき、携帯電話事業者により割り当てられた携帯電話利用帯域内の一般交信用の周波数とは別に1つの特定周波数を同時送信用に割り当てておき、前記携帯用交換局が、各種情報プロバイダから送られてきた情報を前記同時送信用の送信先情報に基づいて、各基地局より前記1つの特定周波数で同時送信を行うことを特徴とする同時送信機能付き携帯電話システムが提案されている(例えば、特許文献2参照)。  In addition, a method of simultaneously transmitting information including voice using a wireless terminal for simultaneous transmission using a preset frequency for a specific user group, that is, a plurality of mobile phones and mobile phones A mobile phone operator that includes a switching center and various information providers connected to the mobile switching center, and registers destination information for simultaneous transmission in the plurality of mobile phones and the mobile switching center. A specific frequency is assigned for simultaneous transmission separately from the frequency of general communication in the mobile phone usage band assigned by the mobile phone, and the mobile switching center sends information sent from various information providers to the simultaneous transmission frequency. There has been proposed a cellular phone system with a simultaneous transmission function that performs simultaneous transmission at the one specific frequency from each base station based on transmission destination information for transmission (for example, References 2).

この特定のグループが利用する移動無線端末は、新たに特定周波数に対応する専用の送受信機能を設備しなければならず、利用者に経済的負担を強い、大衆性を損ない特定の利用者のみが利益を得るシステムである。  The mobile radio terminal used by this specific group must be newly equipped with a dedicated transmission / reception function corresponding to the specific frequency. This is a profitable system.

携帯電話を介して非常事態や災害時に強制的に通報を行い、多くの人に危険を通知できる通信システムとして、基地局に指示を出力するメインホスト局と、メインホスト局からの指示に従って特定のデータを送信する基地局と、基地局から伝送される前記特定のデータを受信した場合に、待ち受け中から通話中か判断し、待ち受け中であれば前記特定のデータに対応する情報をディスプレイに表示する移動局とを備え、移動局に、緊急データとそれに対応する緊急メッセージとを対応させて記憶する緊急データテーブルを備え、緊急時には、基地局がメインホスト局からの指示に従って、特定のデータを入れて送信し、移動局が特定のデータを受信すると、緊急データテーブルを参照して、対応する緊急メッセージをディスプレイに出力する携帯電話システムが提案されている(例えば、特許文献3参照)。  As a communication system that can forcibly report emergency situations and disasters via mobile phones and notify the danger to many people, a main host station that outputs instructions to the base station, and specific instructions according to instructions from the main host station When a base station that transmits data and the specific data transmitted from the base station are received, it is determined whether the call is in a standby state, and if it is in a standby state, information corresponding to the specific data is displayed on the display. The mobile station has an emergency data table for storing the emergency data and the corresponding emergency message in correspondence with each other, and in the event of an emergency, the base station sends specific data according to the instruction from the main host station. When the mobile station receives specific data, it refers to the emergency data table and outputs the corresponding emergency message to the display. Band telephone system has been proposed (e.g., see Patent Document 3).

このシステムは、制御チャネル上の基地局からの下り制御コマンドに特定のデータを入れて送信しており、受信局は制御チャネル上の下りコマンドの特定データを常に監視している。  In this system, specific data is transmitted in the downlink control command from the base station on the control channel, and the receiving station constantly monitors the specific data of the downlink command on the control channel.

近年、一般公衆放送を受信できる機能を付加した携帯端末も商業化され、放送局が商用放送の送信中でも緊急性の高い緊急放送を送信し視聴者が受信できる様な広域なシステムなども提供されている。  In recent years, mobile terminals with the function of receiving general public broadcasts have also been commercialized, and a wide-area system that allows viewers to receive emergency broadcasts and receive viewers even while commercial broadcasts are being transmitted is also provided. ing.

この商用放送時の緊急放送を移動無線端末で受信すれば視聴者には一定の効果が期待できるが、その放送を視聴していなければ視聴者に警報を伝達されないため、効果は限定的であり、放送波はその目的から広い範囲をカバーする使命を有していることから、当該地域以外の地域では緊急警報の報知は無用の混乱を与えるおそれがある。  If an emergency broadcast at the time of commercial broadcasting is received by a mobile wireless terminal, a certain effect can be expected for the viewer. However, if the broadcast is not viewed, an alarm is not transmitted to the viewer, so the effect is limited. Since broadcast waves have a mission to cover a wide range for that purpose, emergency alerts may cause unnecessary confusion in regions other than the region concerned.

また、近年、携帯端末にも緊急警報放送EWS(Emergency Warning System)を受信する移動無線端末も考えられているが、EWSを受信するために専用の受信機能が必要で、その機能を集約した集積回路の開発も行われているが、携帯端末としての機能以外に専用回路が電力を消費し、携帯端末の構造が複雑になるなど現実的でない。
特許第3050393号公報特許第3504584号公報特開2005−204326号公報
In recent years, mobile wireless terminals that receive emergency warning broadcast EWS (Emergency Warning System) are also considered for mobile terminals, but a dedicated reception function is required to receive EWS, and this function is integrated. Although a circuit has been developed, it is not practical because the dedicated circuit consumes power in addition to the function as a portable terminal and the structure of the portable terminal becomes complicated.

The mobile communication control station 3 is installed for each location registration area, and the mobile terminal 1 may move even if it moves. In the location registration area 6, a control signal for controlling the signal strength and the channel is transmitted so that a communication line with the portable terminal 1 can be established at any time by a technique called hand-order or communication is maintained. 2 is always transmitted.

緊急情報発信源7は、気象庁から発信される緊急地震情報などの緊急警報を緊急警報の内容に対応したエリアの無線基地局へ通知する機能を有している。  The emergencyinformation transmission source 7 has a function of notifying an emergency alert such as emergency earthquake information transmitted from the Japan Meteorological Agency to a radio base station in an area corresponding to the content of the emergency alert.

PDCシステム(Personal Digital Cellular)では、通話以外に制御チャネルがあり、無線基地局は在圏する全ての携帯端末に対する制御信号として図5に示すCAC(Common Access Channel)フレーム構造を有する携帯端末に対する1対多または1対1の制御信号の交信が行われている。CACフレームには、端末呼出スロット(ページングと言う、Paging Channel.PCHスロット)、端末の送信電力設定スロット(Signaling Control Channel.PCCHスロット)、とまり木チャネル情報スロット(Broadcasting Channel.BCCHスロット)などが、同一チャネルで無線基地局2から携帯端末1への下り通信または双方向通信で定期的に送信されており、在圏する携帯端末との回線の確立を即時確保できる様なシステム構造を取っている。  In the PDC system (Personal Digital Cellular), there is a control channel in addition to a telephone call, and the wireless base station is 1 for a mobile terminal having a CAC (Common Access Channel) frame structure shown in FIG. 5 as a control signal for all mobile terminals in the area. Communication of one-to-many or one-to-one control signals is performed. The CAC frame has the same terminal call slot (called paging, Paging Channel.PCH slot), terminal transmission power setting slot (Signaling Control Channel.PCCH slot), perch channel information slot (Broadcasting Channel.BCCH slot), etc. It is regularly transmitted by downlink communication or two-way communication from the radio base station 2 to the mobile terminal 1 through the channel, and has a system structure that can immediately secure establishment of a line with the mobile terminal in the area.

ここで、携帯端末識別番号は、図2に示す構造を有している。先頭の“0”はNTT回線網からみて市外を、“A,B”の2桁は携帯電話網を、“C,D,E”は携帯電話事業者番号を、“F〜J”までの5桁が携帯端末番号を表す番号が割り当てられている。  Here, the mobile terminal identification number has the structure shown in FIG. “0” at the head is out of the city as seen from the NTT network, “A, B” is the mobile phone network, “C, D, E” is the mobile phone operator number, and “F to J” Are assigned numbers that represent mobile terminal numbers.

That is, as the common emergency alert number, for example, when a user who is said to be a bad number is assigned a number that is not actually sold, and when an earthquake alert is issued, “090 999 99999” is set as the earthquake alert, “090 444 44444” is assigned to the tsunami warning.

無線基地局2は、可変長CACフレーム呼出す携帯端末番号をセットして送信する。携帯端末1は、無線基地局2から受信したCACフレーム内のPCHスロットに自端末番号を検出した時には、無線基地局2に受信信号強度などを送信する。さらに、無線基地局2は認証番号などを送り、端末が認証応答して回線が確立される。携帯端末1は、上記機能に加えて、緊急警報用番号があるか否かを判断し、緊急警報用番号を検出したときに、テーブルを参照して、当該緊急警報用番号に対応する、着信音を選択して発音したり、表示内容を表示画面に表示する機能をも有している、  The radio base station 2 sets and transmits the mobile terminal number for calling the variable length CAC frame. When the mobile terminal 1 detects its own terminal number in the PCH slot in the CAC frame received from the radio base station 2, the mobile terminal 1 transmits received signal strength and the like to the radio base station 2. Further, the wireless base station 2 sends an authentication number and the like, and the terminal responds with an authentication response to establish a line. In addition to the above functions, the mobile terminal 1 determines whether or not there is an emergency alert number, and when detecting the emergency alert number, the mobile terminal 1 refers to the table and corresponds to the emergency alert number. It also has a function to select and pronounce a sound, and to display the display contents on the display screen.

CACフレームのPCHスロットは、無線基地局2から見て1対多の呼出であり、携帯端末1は、受信したCACフレーム内のPCHスロットを見て、自端末宛のPHCスロットがあるか否かを定期的に監視している。  The PCH slot of the CAC frame is a one-to-many call as viewed from the radio base station 2, and the mobile terminal 1 looks at the PCH slot in the received CAC frame and determines whether there is a PHC slot addressed to itself. Are regularly monitored.

本発明における緊急を要する警報としては、地震動の本震動が伝わる前の初期微動が上げられる。地震動はまず伝搬速度が早く振幅の小さいP波が到達し、震源からの距離にもよるが数秒〜数十秒後に大きな揺れを伴うS波が伝わる。つまり、本震動S波はP波より伝わる早さが遅いため、この伝達時間差を利用し、一定の大きさのP波を検知後に当該箇所では大きな揺れを伴う本震動が到達することが予測可能である。緊急情報発信源7は、気象庁からの緊急地震速報を受信すると、緊急地震情報に搭載されている地震の発生地域に関する情報を解析して、必要とする移動通信制御局3または移動通信交換機4へ、緊急警報信号を送信する。  As an alarm that requires urgency in the present invention, the initial tremor before the main ground motion of the ground motion is transmitted is raised. First, P waves with a small propagation velocity reach the ground motion, and S waves with large shaking are transmitted after several seconds to several tens of seconds depending on the distance from the epicenter. In other words, since the speed of the main shock S wave is slower than that of the P wave, it is possible to predict that a main vibration with a large tremor will arrive at the location after detecting a P wave of a certain magnitude using this transmission time difference. It is. When the emergencyinformation transmission source 7 receives the earthquake early warning from the Japan Meteorological Agency, it analyzes the information about the earthquake occurrence area loaded in the emergency earthquake information and sends it to the required mobile communication control station 3 or mobile communication switch 4 Send an emergency alert signal.

移動通信交換機4または移動通信制御局3に接続される緊急警報信号源7から、当該位置登録エリアに対して緊急警報信号を発信したとき、当該位置登録エリア6に位置している全ての無線基地局2からCACフレームのPCHスロットに緊急警報用番号を、SCCHスロットにそれに関連する情報(地震警報であれば震度階、震源など、津波警報であれば津波の高さ、到達時間)をセットして在圏する全ての携帯端末1に対して送信する。  When an emergency alert signal is transmitted from the emergencyalert signal source 7 connected to the mobile communication switch 4 or the mobile communication control station 3 to the location registration area, all the radio bases located in the location registration area 6 Station 2 sets the emergency warning number in the PCH slot of the CAC frame, and information related to it in the SCCH slot (intensity level, epicenter, etc. for earthquake warnings, tsunami height, arrival time for tsunami warnings) To all mobile terminals 1 that are in the area.

このとき、緊急警報を発信する無線基地局2は、前記PCHスロットを含めたCACフレームを送信するのみで、通常の回線を確立するための回線確立シーケンスは実行しないでCACフレーム送信に関する処理を終了する。  At this time, the radio base station 2 that issues an emergency alert only transmits the CAC frame including the PCH slot, and does not execute the line establishment sequence for establishing a normal line, and ends the process related to CAC frame transmission. To do.

携帯端末1は、緊急警報用番号を受信すると予めその番号に対応する緊急警報報知プログラムを実行し、無線基地局との回線を確立するための通常の回線確立シーケンスは、実行しない。  When receiving the emergency alert number, the mobile terminal 1 executes an emergency alert notification program corresponding to the number in advance, and does not execute a normal line establishment sequence for establishing a line with the radio base station.

PDCでは受信強度をチェックしたり無線基地局のハンドオーバをする必要から通話以外に制御チャネルが設定されているので、本発明は通話中であっても、携帯端末1はCACフレームを受信しPCHスロットをチェックするプログラムを動作させることができるので、緊急警報用番号を検出した場合、前記緊急警報報知プログラムを起動させることができる。  In the PDC, since the control channel is set in addition to the call because it is necessary to check the reception strength or perform handover of the radio base station, the mobile terminal 1 receives the CAC frame and receives the PCH slot even during a call. Since the emergency warning number is detected, the emergency warning notification program can be started.

携帯端末1に設定される緊急警報表示プログラムは、通常の電話着信音やメールなどの着信音と明瞭に識別できるサイン音を用い、利用者が着信音のみで緊急警報と識別できるものであることが望ましい。  The emergency alert display program set in the mobile terminal 1 uses a signature sound that can be clearly distinguished from a ringtone such as a normal telephone ringtone or mail, and allows the user to identify an emergency alert only by the ringtone. Is desirable.

また、携帯端末1が震動して着信を知らせるマナーモードなどの設定時でも前記サイン音で利用者に緊急警報で有ることを知らせることが望ましい。携帯端末1は、埋め込まれたキーを用いて当該緊急警報用番号を受信時に予めプログラムされた緊急警報メッセージを発する。  In addition, it is desirable to notify the user that there is an emergency alert with the above-mentioned sign sound even when setting the manner mode in which the mobile terminal 1 is shaken to notify an incoming call. The portable terminal 1 issues a pre-programmed emergency alert message when receiving the emergency alert number using the embedded key.

図3を用いて、緊急警報が携帯端末利用者に伝わるまでの一連の動作を説明する。緊急警報発信源7は、概要とし次のプログラムが組み込まれたシステムで、気象庁が運営する緊急地震速報を受信し、当該エリアでの震度予測、到達時間などを解析し、災害が予測されると判断されるとき、または海岸付近では該情報を解析し津波の到来を予測されるとき、該蔵する位置登録エリア6内の移動通信制御局3に対して専用通信回線を通じて緊急警報信号として情報を出力する。または、緊急警報発信源7は、移動通信交換機4に対して発信エリアを指定して緊急警報信号として情報を出力する。    A series of operations until the emergency alert is transmitted to the mobile terminal user will be described with reference to FIG. Theemergency alert source 7 is a system that incorporates the following program as an overview, receives earthquake early warnings operated by the Japan Meteorological Agency, analyzes seismic intensity predictions, arrival times, etc. in the area, and predicts disasters When it is judged, or when the information is analyzed near the coast and the arrival of a tsunami is predicted, the mobile communication control station 3 in the location registration area 6 is provided with information as an emergency warning signal through a dedicated communication line.
