Description

無線端末Wireless terminal
　本発明は無線端末に関し、特に航空機内などで使用が制限される無線通信を行う無線端末に関する。 The present invention relates to a wireless terminal, and more particularly to a wireless terminal that performs wireless communication whose use is restricted in an airplane or the like.
　現在、個人用の情報通信機器として、携帯電話が広く普及している。携帯電話には、音声通話やメールといった通信機能の他に幅広い機能を備えている。例えば、インターネットのブラウジング機能、音楽／映像の再生用プレーヤとしての機能、ＴＶやラジオの視聴機能、さらには、各種の決済サービスなどがある。 Currently, mobile phones are widely used as personal information communication devices. Mobile phones have a wide range of functions in addition to communication functions such as voice calls and emails. For example, there are an Internet browsing function, a music / video playback function, a TV / radio viewing function, and various payment services.
　携帯電話は、情報通信端末として稼動する際、各種情報データを電磁波で送受信する。このため、電磁波の届かない圏外地域では、携帯電話の機能は、大きく制限される。
　また、携帯電話の発生する電磁波は、他の機器に対して誤動作等の影響を与える可能性があることから、安全上の理由により、航空機内や病院内で電源のオフが求められる場合がある。この場合、携帯電話は、全く使用することができなくなる。 When a mobile phone operates as an information communication terminal, it transmits and receives various information data using electromagnetic waves. For this reason, the function of a mobile phone is greatly restricted in an out-of-service area where electromagnetic waves do not reach.
In addition, because electromagnetic waves generated by mobile phones may affect other devices such as malfunctions, it may be required to turn off the power in airplanes or hospitals for safety reasons. . In this case, the mobile phone cannot be used at all.
　一般に、携帯電話の電源オフ操作を行い、電磁波の発生を停止させる行為は、使用禁止場所に立ち入る際の注意書きや客室乗務員による指示に従って実施される。しかし、携帯電話は、一般に個人所有の情報端末であり、電源オフを自分で実施するため、代替の通信設備が用意されない場合に、故意に電源オフを行わない場合が発生する。または、単なる過失による切り忘れが発生する。 In general, the act of turning off the power of a mobile phone and stopping the generation of electromagnetic waves is carried out in accordance with precautions when entering a prohibited place and instructions by flight attendants. However, a mobile phone is generally an information terminal that is personally owned, and since the power is turned off by itself, there is a case where the power is not intentionally turned off when an alternative communication facility is not prepared. Or forgetting to cut by simple mistakes occurs.
　なお、従来、携帯電話機において、空気を媒体として各種情報の配信を受けることができる情報提供システムが提供されている（例えば、特許文献１参照）。
特開２００７－１３９２５号公報 Conventionally, in a mobile phone, an information providing system that can receive distribution of various types of information using air as a medium has been provided (see, for example, Patent Document 1).
JP 2007-13925 A
　このように、電磁波が制限される場所では、無線端末を使用することができないという問題点があった。
　本発明はこのような点に鑑みてなされたものであり、電磁波が制限される場所でも無線端末を使用することができる無線端末を提供することを目的とする。 Thus, there is a problem that the wireless terminal cannot be used in a place where electromagnetic waves are restricted.
The present invention has been made in view of these points, and an object thereof is to provide a wireless terminal that can use the wireless terminal even in a place where electromagnetic waves are restricted.
　本発明では上記問題を解決するために、無線通信を行う無線端末が提供される。この無線端末は、外部からコマンドを受付けるコマンド受付け手段と、前記コマンドに応じて、電磁波を発生する無線回路部位の電源をオフする電源制御手段と、前記コマンドに応じて、音声帯域のアナログ信号を受信し、デジタル信号に変換する信号変換手段と、を有する。 In the present invention, in order to solve the above problem, a wireless terminal that performs wireless communication is provided. The wireless terminal includes command receiving means for receiving a command from the outside, power supply control means for turning off the power of a wireless circuit part that generates an electromagnetic wave according to the command, and an analog signal in a voice band according to the command. Signal converting means for receiving and converting into a digital signal.
　このような無線端末によれば、コマンドに応じて、電磁波を発生する無線回路部位の電源をオフする。また、音声帯域のアナログ信号を受信し、デジタル信号に変換する。 According to such a wireless terminal, the power of the wireless circuit part that generates the electromagnetic wave is turned off in response to the command. It also receives an analog signal in the voice band and converts it into a digital signal.
　開示の装置では、電磁波が制限される場所でも、無線端末を使用することができる。
　本発明の上記および他の目的、特徴および利点は本発明の例として好ましい実施の形態を表す添付の図面と関連した以下の説明により明らかになるであろう。 In the disclosed apparatus, a wireless terminal can be used even in a place where electromagnetic waves are restricted.
These and other objects, features and advantages of the present invention will become apparent from the following description taken in conjunction with the accompanying drawings which illustrate preferred embodiments by way of example of the present invention.

　以下、本発明の原理を図面を参照して詳細に説明する。
　図１は、無線端末の概要を示した図である。図には、航空機２と、航空機２に設置された映像／音楽配信装置２ａが示してある。また、航空機２の搭乗者が所有する、例えば、携帯電話である無線端末１が示してある。 Hereinafter, the principle of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram illustrating an outline of a wireless terminal. In the figure, an aircraft 2 and a video / music distribution device 2a installed on the aircraft 2 are shown. In addition, a wireless terminal 1 that is owned by a passenger of the aircraft 2 and that is a mobile phone, for example, is shown.
　映像／音楽配信装置２ａは、音声帯域のアナログ信号で、映像や音楽などの配信サービスを提供する。
　無線端末１は、コマンド受付け手段１ａ、電源制御手段１ｂ、および信号変換手段１ｃを有している。 The video / music distribution device 2a provides a distribution service such as video and music with an analog signal in the audio band.
The wireless terminal 1 includes command receiving means 1a, power supply control means 1b, and signal conversion means 1c.
　コマンド受付け手段１ａは、外部からコマンドを受付ける。このコマンドは、例えば、当該無線端末１の所有者は入力できず、所有者以外の第三者のみが入力できる。例えば、無線端末１の所有者が航空機２に搭乗する際に、航空機２の航空事業者のみがコマンドを入力できる。 The command receiving means 1a receives a command from the outside. For example, this command cannot be input by the owner of the wireless terminal 1 but can be input only by a third party other than the owner. For example, when the owner of the wireless terminal 1 gets on the aircraft 2, only the airline operator of the aircraft 2 can input a command.
　電源制御手段１ｂは、コマンド受付け手段１ａの受付けたコマンドに応じて、電磁波を発生する無線回路部位の電源をオフする。これにより、無線端末１は、電磁波を発することなく、無線通信以外の他の機能を使用することができ、例えば、映像／音楽配信装置２ａから配信される映像を、無線端末１の表示装置で視聴できる。また、コマンドは、航空事業者のみが入力できるので、無線端末１の所有者は、搭乗中に勝手に無線回路部位の電源をオンして無線通信することはできない。 The power control means 1b turns off the power of the radio circuit part that generates the electromagnetic wave in accordance with the command received by the command receiving means 1a. As a result, the wireless terminal 1 can use functions other than wireless communication without emitting electromagnetic waves. For example, an image distributed from the image / music distribution device 2a can be displayed on the display device of the wireless terminal 1. Can watch. Further, since the command can be input only by the air carrier, the owner of the wireless terminal 1 cannot wirelessly communicate by turning on the power of the wireless circuit part without permission during boarding.
　信号変換手段１ｃは、コマンド受付け手段１ａの受付けたコマンドに応じて、音声帯域のアナログ信号を受信し、デジタル信号に変換する。例えば、信号変換手段１ｃは、映像／音楽配信装置２ａから配信される映像や音楽などの音声帯域のアナログ信号を、デジタル信号に変換する。すなわち、無線端末１は、航空機２内で、映像や音楽などの配信サービスを受けることができる。 The signal conversion means 1c receives an analog signal in the voice band according to the command received by the command reception means 1a and converts it into a digital signal. For example, the signal converting means 1c converts an analog signal in an audio band such as video or music distributed from the video / music distribution device 2a into a digital signal. That is, the wireless terminal 1 can receive distribution services such as video and music in the aircraft 2.
　このように、無線端末１は、コマンドに応じて、電磁波を発生する無線回路部位の電源をオフするようにした。これにより、電磁波を発生することなく、音声帯域のアナログ信号を受信してデジタル信号に変換し、データ受信をすることが可能となり、電磁波が制限される場所でも、無線端末１を使用することができるようになる。 In this way, the wireless terminal 1 turns off the power of the wireless circuit part that generates the electromagnetic wave in accordance with the command. As a result, it is possible to receive an analog signal in a voice band and convert it into a digital signal without generating an electromagnetic wave, and to receive data. The wireless terminal 1 can be used even in a place where the electromagnetic wave is restricted. become able to.
　また、第三者によって入力されるコマンドによって、無線回路部位の電源をオン・オフすることにより、無線端末の電源オフを求められる航空機内でも、故意や過失による電磁波の発生を防止することができる。 In addition, by turning on / off the power of the radio circuit portion by a command input by a third party, it is possible to prevent the generation of electromagnetic waves due to intentional or negligence even in an aircraft that requires the radio terminal to be powered off. .
　次に、本発明の第１の実施の形態を図面を参照して詳細に説明する。
　図２は、第１の実施の形態に係る携帯電話を適用したシステム構成例を示した図である。図に示すように、航空機２０は、映像／音楽配信装置２１、選択スイッチ２２、およびジャック２３を有している。 Next, a first embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 2 is a diagram illustrating a system configuration example to which the mobile phone according to the first embodiment is applied. As shown in the figure, the aircraft 20 has a video / music distribution device 21, a selection switch 22, and a jack 23.
　航空機２０に搭乗する利用者は、自分の携帯電話１０を持って、航空機２０に搭乗している。航空機２０に搭乗している利用者は、ジャック２３に、携帯電話１０に接続されたプラグを接続することにより、映像／音楽配信サービスを携帯電話１０で受けることができる。 A user boarding the aircraft 20 is carrying the aircraft 20 with his / her mobile phone 10. A user on board the aircraft 20 can receive a video / music distribution service with the mobile phone 10 by connecting a plug connected to the mobile phone 10 to the jack 23.
　携帯電話１０は、電源をオンしても、無線通信を行うための無線回路部分のみをオフする機能を有している。この無線回路部分のオフ／オフは、航空事業者のみが行えるようになっており、携帯電話１０の利用者（所有者）は、自由に無線回路部分をオン／オフできないようになっている。 The cellular phone 10 has a function of turning off only a wireless circuit portion for performing wireless communication even when the power is turned on. This wireless circuit portion can be turned off / off only by an airline operator, and the user (owner) of the mobile phone 10 cannot freely turn on / off the wireless circuit portion.
　映像／音楽配信サービスは、音声帯域の信号により配信される。携帯電話１０は、無線回路部分をオフした場合に、映像／音楽配信サービスの音声帯域の信号を受信できるようになっている。従って、携帯電話１０の所有者は、航空機２０内で映像／音楽配信サービスを受けるには、航空機２０の搭乗前に、航空事業者により、携帯電話１０の無線回路部分をオフしてもらう必要がある。 The video / music distribution service is distributed using audio band signals. The cellular phone 10 can receive a signal in the audio band of the video / music distribution service when the wireless circuit portion is turned off. Therefore, in order to receive the video / music distribution service in the aircraft 20, the owner of the mobile phone 10 needs to have the wireless circuit portion of the mobile phone 10 turned off by the airline operator before boarding the aircraft 20. is there.
　映像／音楽配信装置２１は、利用者に映像／音楽配信サービスを提供する装置である。映像／音楽配信装置２１は、例えば、映画、観光情報、ＴＶゲームなどの映像サービスおよび音楽やニュースなどの音声のみのオーディオサービスを提供する。映像／音楽配信装置２１は、音声帯域の信号で映像／音楽配信サービスを提供する。 The video / music distribution device 21 is a device that provides a video / music distribution service to the user. The video / music distribution device 21 provides, for example, video services such as movies, sightseeing information, TV games, and audio-only audio services such as music and news. The video / music distribution device 21 provides a video / music distribution service using an audio band signal.
　選択スイッチ２２は、複数ある映像サービスや音楽サービスを選択するためのスイッチである。利用者は、選択スイッチ２２のチャンネル操作によって、自分の望む映像／音楽配信サービスを受けることができる。 The selection switch 22 is a switch for selecting a plurality of video services and music services. The user can receive the desired video / music distribution service by operating the channel of the selection switch 22.
　ジャック２３は、各座席に設けられたヘッドホン端子であり、携帯電話１０やヘッドホンが接続される。例えば、乗客は、映像サービスを受けたい場合、携帯電話１０と接続されたプラグをジャック２３に接続する。これにより、携帯電話１０のディスプレイには、映像が映し出され、乗客は、映像サービスを受けることができる。また、乗客は、オーディオサービスを受けたい場合、ヘッドホンのプラグをジャック２３に接続する。これにより、乗客は、ヘッドホンからオーディオサービスを受けることができる。 Jack 23 is a headphone terminal provided in each seat, to which the mobile phone 10 or headphones are connected. For example, when a passenger wants to receive a video service, he / she connects a plug connected to the mobile phone 10 to the jack 23. Thereby, an image is displayed on the display of the mobile phone 10, and the passenger can receive an image service. The passenger connects the plug of the headphone to the jack 23 when receiving the audio service. Thereby, the passenger can receive the audio service from the headphones.
　なお、選択スイッチ２２およびジャック２３は、１つしか示してないが、航空機２０内の各座席に設けられている。また、選択スイッチ２２およびジャック２３は、従来から航空機２０に設置されているものを利用する。 Note that only one selection switch 22 and one jack 23 are shown, but they are provided in each seat in the aircraft 20. As the selection switch 22 and the jack 23, those conventionally installed in the aircraft 20 are used.
　このように、携帯電話１０は、電磁波を発生する無線回路部分をオン／オフする機能を有し、音声帯域の信号によって、映像／音楽配信サービスを航空機２０内で受けることができるようにした。これにより、電磁波が制限される航空機２０内でも、携帯電話１０を使用することができる。 As described above, the mobile phone 10 has a function of turning on / off a radio circuit portion that generates electromagnetic waves, and can receive a video / music distribution service in the aircraft 20 by a signal in a voice band. Accordingly, the mobile phone 10 can be used even in the aircraft 20 where electromagnetic waves are restricted.
　また、携帯電話１０の無線回路部分のオン／オフは、携帯電話１０の所有者が自由に設定することができないため、故意や過失により、電磁波が発生することがなく、航空機２０の安全性を保つことができる。 In addition, since the owner of the mobile phone 10 cannot set the wireless circuit portion of the mobile phone 10 on and off, electromagnetic waves are not generated due to intentional or negligence, and the safety of the aircraft 20 can be improved. Can keep.
　また、従来から航空機２０に設置されている選択スイッチ２２やジャック２３の設備を利用することにより、低コストで乗客に対し映像サービスを提供することができる。
　図３は、携帯電話のブロック図である。図の制御部３０は、携帯電話１０の全体を制御する。例えば、無線通話やデータの送受信を制御する。 In addition, by using the equipment of the selection switch 22 and the jack 23 that are conventionally installed in the aircraft 20, video services can be provided to passengers at low cost.
FIG. 3 is a block diagram of a mobile phone. The control unit 30 in the figure controls the entire mobile phone 10. For example, it controls wireless communication and data transmission / reception.
　制御部３０は、第三者制御部３０ａを有している。第三者制御部３０ａは、携帯電話１０の所有者以外の第三者からのコマンドを受付け、受付けたコマンドに基づいて、携帯電話１０を制御する。例えば、第三者制御部３０ａは、第三者から受付けたコマンドに基づいて、ＲＦ（Radio Frequency）停止制御部３４に、ＲＦ部４３をオン／オフするように指示する。また、第三者制御部３０ａは、航空事業者から受付けたコマンド内容を第三者設定情報メモリ３６に書き込む。なお、第三者は、例えば、航空事業者である（以下、第三者は航空事業者とする）。 The control unit 30 has a third party control unit 30a. The third party control unit 30a receives a command from a third party other than the owner of the mobile phone 10, and controls the mobile phone 10 based on the received command. For example, the third party control unit 30a instructs an RF (Radio Frequency) stop control unit 34 to turn on / off the RF unit 43 based on a command received from a third party. In addition, the third party control unit 30 a writes the command content received from the airline operator in the third party setting information memory 36. The third party is, for example, an air carrier (hereinafter, the third party is an air carrier).
　第三者制御部３０ａは、第三者認証登録部３０ａａを有している。第三者認証登録部３０ａａは、フィルタ条件に適合したコマンドのみ受付ける。すなわち、第三者制御部３０ａは、フィルタ条件に適合しないコマンドは、受付けないようにする。 The third party control unit 30a has a third party authentication registration unit 30aa. The third-party authentication registration unit 30aa accepts only commands that meet the filter conditions. That is, the third party control unit 30a does not accept commands that do not meet the filter conditions.
　なお、制御部３０は、例えば、ＣＰＵ（Central Processing Unit）である。第三者制御部３０ａおよび第三者認証登録部３０ａａは、ＣＰＵがプログラムを実行することにより、実現される機能である。 The control unit 30 is, for example, a CPU (Central Processing Unit). The third party control unit 30a and the third party authentication registration unit 30aa are functions realized by the CPU executing a program.
　入力装置３１は、カメラ３１ａ、非接触ＩＣチップ３１ｂ、およびキーパッド３１ｃを有している。入力装置３１は、これらの入力装置によって、外部からのデータを入力する。 The input device 31 includes a camera 31a, a non-contact IC chip 31b, and a keypad 31c. The input device 31 inputs data from the outside using these input devices.
　利用者認証部３２は、携帯電話１０の所有者の認証を行う。利用者認証部３２は、入力装置３１から入力されるデータに基づいて、利用者が適正な利用者（携帯電話１０の所有者）であるか否か判断する。 The user authentication unit 32 authenticates the owner of the mobile phone 10. The user authentication unit 32 determines whether the user is an appropriate user (owner of the mobile phone 10) based on data input from the input device 31.
　制御切替え部３３は、利用者の要求に応じて、入力装置３１から入力されるデータを第三者認証登録部３０ａａに出力するか、制御部３０に出力するか切替える。制御部切替え部３３は、通常、入力装置３１からのデータを制御部３０に出力するようにしているが、利用者からデータ出力の切替え要求があり、その要求を行った利用者が利用者認証部３２で適正な利用者と判断された場合に、入力装置３１のデータを第三者認証登録部３０ａａに出力するようにする。 The control switching unit 33 switches whether data input from the input device 31 is output to the third-party authentication registration unit 30aa or to the control unit 30 in response to a user request. The control unit switching unit 33 normally outputs the data from the input device 31 to the control unit 30, but there is a data output switching request from the user, and the user who made the request is authenticated by the user. When the unit 32 determines that the user is an appropriate user, the data of the input device 31 is output to the third party authentication registration unit 30aa.
　例えば、上述したように、第三者制御部３０ａにコマンドを送ることができるのは、航空事業者である。航空事業者は、利用者が利用者認証部３２で認証を行った場合のみ、第三者制御部３０ａにコマンドを送ることができる。すなわち、携帯電話１０の所有者が許可（認証手続）しない限り、航空事業者は、勝手に第三者制御部３０ａにコマンドを送ることができないようになっている。また、携帯電話１０の所有者は、第三者認証登録部３０ａａのフィルタ条件によって、勝手に第三者制御部３０ａにコマンドを送ることができないようになっている。 For example, as described above, it is an airline operator that can send a command to the third party control unit 30a. The airliner can send a command to the third party control unit 30a only when the user authenticates with the user authentication unit 32. That is, unless the owner of the mobile phone 10 permits (authentication procedure), the airline operator cannot send a command to the third party control unit 30a without permission. Further, the owner of the mobile phone 10 cannot send a command to the third party control unit 30a without permission according to the filter condition of the third party authentication registration unit 30aa.
　ＲＦ停止制御部３４は、第三者制御部３０ａの制御に応じて、ＲＦ部４３の電源をオン／オフする。これにより、携帯電話１０は、他の部位がオンしていても、電磁波を発するＲＦ部４３のみ電源をオフすることができる。 The RF stop control unit 34 turns on / off the power of the RF unit 43 according to the control of the third party control unit 30a. As a result, the mobile phone 10 can turn off the power of only the RF unit 43 that emits electromagnetic waves, even if other parts are turned on.
　ＲＦ停止表示部３５は、ＲＦ部４３のオン／オフ状態を表示する。これにより、航空機２０の乗務員は、乗客から携帯電話１０の提示してもらうことにより、一目で携帯電話１０の無線回路部分がオンしているかオフしているか知ることができる。なお、ＲＦ部４３のオン／オフ状態は、ＬＣＤ（Liquid Crystal Display）４６に表示するようにしてもよい。 The RF stop display unit 35 displays the on / off state of the RF unit 43. Thereby, the crew member of the aircraft 20 can know at a glance whether the wireless circuit portion of the mobile phone 10 is turned on or off by having the passenger present the mobile phone 10. The on / off state of the RF unit 43 may be displayed on an LCD (Liquid Crystal Display) 46.
　第三者設定情報メモリ３６には、航空事業者が送信したコマンドに含まれる情報が設定される。例えば、モデム３８の通信速度や圧縮方法などが設定される。第三者設定情報メモリ３６は、例えば、フラッシュメモリなどで構成される。 In the third party setting information memory 36, information included in the command transmitted by the airline operator is set. For example, the communication speed and compression method of the modem 38 are set. The third party setting information memory 36 is composed of, for example, a flash memory.
　モデム制御部３７は、第三者設定情報メモリ３６のデータに基づいて、モデム３８の制御を行う。例えば、モデム３８の通信速度や圧縮方法などを制御する。
　モデム３８は、外部から入力される音声帯域の信号をデジタル信号に変換し、制御部３０に出力する。また、制御部３０から出力されるデジタル信号を音声帯域のアナログ信号に変換して切替え回路４０に出力する。モデム３８は、例えば、ＩＴＵ－ＴのＶシリーズの勧告に基づいて、データをアナログ－デジタル変換する。 The modem control unit 37 controls the modem 38 based on the data in the third party setting information memory 36. For example, the communication speed and compression method of the modem 38 are controlled.
The modem 38 converts an audio band signal input from the outside into a digital signal and outputs the digital signal to the control unit 30. In addition, the digital signal output from the control unit 30 is converted into an analog signal in the voice band and output to the switching circuit 40. The modem 38 performs analog-to-digital conversion of data based on, for example, the ITU-T V series recommendation.
　音声信号入出力装置３９は、スピーカ３９ａ、マイク３９ｂ、接続端子３９ｃ、および有線電話で使用されるモジュラジャック３９ｄを有している。接続端子３９ｃは、航空機２０のジャック２３に接続され、映像／音楽配信装置２１から配信される音声帯域の信号を受信できるようになっている。 The audio signal input / output device 39 has a speaker 39a, a microphone 39b, a connection terminal 39c, and a modular jack 39d used in a wired telephone. The connection terminal 39 c is connected to the jack 23 of the aircraft 20 and can receive a signal in an audio band distributed from the video / music distribution device 21.
　切替え回路４０は、第三者制御部３０ａの制御に応じて、音声信号入出力装置３９から入力される信号を音声インターフェース部４１に出力するか、モデム３８に出力するか切替える。切替え回路４０は、通常、音声信号入出力装置３９から入力される信号を音声インターフェース部４１に出力するようにしているが、第三者制御部３０ａからの要求により、モデム３８に出力するようにする。 The switching circuit 40 switches whether to output a signal input from the audio signal input / output device 39 to the audio interface unit 41 or to the modem 38 under the control of the third party control unit 30a. The switching circuit 40 normally outputs a signal input from the audio signal input / output device 39 to the audio interface unit 41, but outputs it to the modem 38 in response to a request from the third party control unit 30a. To do.
　ベースバンド信号処理部４２は、アンテナへ出力する信号のベースバンド処理を行い、また、アンテナから受信された信号のベースバンド処理を行う。
　ＲＦ部４３は、ベースバンド帯の周波数の信号を無線信号の周波数に変換してアンテナへ出力する。また、ＲＦ部４３は、アンテナによって受信された無線信号をベースバンド帯の周波数に変換する。なお、ＲＦ部４３が上述した無線通信を行うための無線回路部分に対応する。従って、ＲＦ停止制御部３４がＲＦ部４３をオフすると（ＲＦ部４３に電源を供給しないようにすると）、携帯電話１０は、電磁波を発することはない。 The baseband signal processing unit 42 performs baseband processing of a signal output to the antenna, and performs baseband processing of a signal received from the antenna.
The RF unit 43 converts a baseband frequency signal into a radio signal frequency and outputs the radio signal to the antenna. Further, the RF unit 43 converts the radio signal received by the antenna into a baseband frequency. The RF unit 43 corresponds to a wireless circuit portion for performing the above-described wireless communication. Accordingly, when the RF stop control unit 34 turns off the RF unit 43 (when power is not supplied to the RF unit 43), the mobile phone 10 does not emit electromagnetic waves.
　メモリ４４には、携帯電話１０の機能を発揮するためのプログラムが格納されている。例えば、無線通信、データの送受信を行うためのプログラムが格納されている。また、メモリ４４には、映像／音楽配信装置２１から配信される映像および音声を再生するためのプログラムが格納されている。 The memory 44 stores a program for demonstrating the functions of the mobile phone 10. For example, a program for wireless communication and data transmission / reception is stored. Further, the memory 44 stores a program for reproducing video and audio distributed from the video / music distribution device 21.
　電源制御部４５は、携帯電話１０の電源を制御する。例えば、携帯電話１０の電源がオンされると、各部に電源が供給されるようにする。
　ＬＣＤ４６は、制御部３０の制御によって、所定の映像を表示する。例えば、携帯電話１０のメニュー画面、映像／音楽配信装置２１から配信される映像などを表示する。 The power supply control unit 45 controls the power supply of the mobile phone 10. For example, when the mobile phone 10 is turned on, power is supplied to each unit.
The LCD 46 displays a predetermined video under the control of the control unit 30. For example, a menu screen of the mobile phone 10, a video distributed from the video / music distribution device 21, and the like are displayed.
　図４は、操作コマンドの一例を示した図である。航空事業者は、例えば、入力装置３１の非接触ＩＣチップ３１ｂから、図に示すようなコマンドを携帯電話１０に入力する。コマンドは、図に示すような各種情報を有している。なお、図のコマンドの上部に示す数字は、コマンドのビット数を示している。 FIG. 4 is a diagram showing an example of the operation command. For example, the airliner inputs a command as shown in the figure to the mobile phone 10 from the non-contact IC chip 31b of the input device 31. The command has various information as shown in the figure. The numbers shown at the top of the command in the figure indicate the number of bits of the command.
　コマンドのフィルタ情報５１，５２には、航空事業者が携帯電話１０にコマンドを入力するためのフィルタ情報が格納される。例えば、図３で説明した第三者設定情報メモリ３６には、予め３６ビットのフィルタ情報が記憶されており、第三者認証登録部３０ａａは、第三者設定情報メモリ３６に記憶されているフィルタ情報と、航空事業者が入力したコマンドのフィルタ情報５１，５２とを比較し、一致した場合のみ、そのコマンドを受付ける。 In the command filter information 51 and 52, filter information for the airliner to input a command to the mobile phone 10 is stored. For example, the third-party setting information memory 36 described in FIG. 3 stores 36-bit filter information in advance, and the third-party authentication registration unit 30aa is stored in the third-party setting information memory 36. The filter information is compared with the filter information 51 and 52 of the command input by the airline operator, and the command is accepted only when they match.
　切替え回路制御情報５３には、携帯電話１０をモデム通信にするか否かを指定する情報が格納される。例えば、航空事業者は、切替え回路制御情報５３を‘０’にすることにより、切替え回路４０のデータの入出力先を音声インターフェース部４１にすることができ、音声通話を可能にすることができる。また、航空事業者は、切替え回路制御情報５３を‘１’にすることにより、切替え回路４０のデータの入出力先をモデム３８にすることができ、モデム通信を可能にすることができる。 In the switching circuit control information 53, information specifying whether or not the mobile phone 10 is set to modem communication is stored. For example, by setting the switching circuit control information 53 to “0”, the airliner can set the data input / output destination of the switching circuit 40 to the voice interface unit 41 and can make a voice call. . In addition, the airliner can set the switching circuit control information 53 to “1” so that the data input / output destination of the switching circuit 40 can be the modem 38 and the modem communication can be performed.
　ＲＦ状態制御情報５４には、ＲＦ部４３をオン／オフする情報が格納される。例えば、航空事業者は、ＲＦ状態制御情報５４を‘０’にすることにより、ＲＦ部４３のみの機能をオンすることができ、電磁波の発生を停止することができる。また、航空事業者は、ＲＦ状態制御情報５４を‘１’にすることにより、ＲＦ部４３の機能をオフすることができ、無線通信を可能にすることができる。 In the RF state control information 54, information for turning on / off the RF unit 43 is stored. For example, the airliner can turn on the function of only the RF unit 43 by setting the RF state control information 54 to “0”, and can stop the generation of electromagnetic waves. Further, the airliner can set the RF state control information 54 to “1” to turn off the function of the RF unit 43 and enable wireless communication.
　第三者設定情報メモリ制御情報５５，５６には、制御部３０がアクセスできるメモリのアドレスが格納される。例えば、航空事業者は、制御部３０が第三者設定情報メモリ３６にアクセスできる先頭アドレスと最終アドレスを指示することができる。 In the third party setting information memory control information 55 and 56, a memory address accessible by the control unit 30 is stored. For example, the airline operator can instruct the start address and the final address at which the control unit 30 can access the third party setting information memory 36.
　設定情報５７には、モデム３８の通信速度が格納される。例えば、航空事業者は、設定情報５７によって、モデム３８の通信速度を指定することができる。
　設定情報５８には、モデム３８の圧縮方法が格納される。例えば、航空事業者は、設定情報５８によって、モデム３８の圧縮方法を指定することができる。 The setting information 57 stores the communication speed of the modem 38. For example, the airliner can specify the communication speed of the modem 38 by the setting information 57.
The setting information 58 stores the compression method of the modem 38. For example, the airliner can specify the compression method of the modem 38 by the setting information 58.
　設定情報５９には、モデム３８の誤り訂正方法が格納される。例えば、航空事業者は、設定情報５９によって、モデム３８の誤り訂正方法を指定することができる。
　なお、図のコマンドの設定情報５７～５９は、第三者設定情報メモリ３６に記憶される。モデム制御部３７は、第三者設定情報メモリ３６に記憶された通信速度などに基づいて、モデム３８を制御する。また、第三者制御部３０ａは、入力されたコマンドの切替え回路制御情報５３およびＲＦ状態制御情報５４に基づいて、切替え回路４０およびＲＦ停止制御部３４を制御する。 The setting information 59 stores an error correction method for the modem 38. For example, the airline operator can specify the error correction method of the modem 38 by the setting information 59.
The command setting information 57 to 59 shown in the figure is stored in the third party setting information memory 36. The modem control unit 37 controls the modem 38 based on the communication speed stored in the third party setting information memory 36. Further, the third party control unit 30a controls the switching circuit 40 and the RF stop control unit 34 based on the switching circuit control information 53 and the RF state control information 54 of the input command.
　図５は、携帯電話を用いた航空機内での映像／音楽配信サービスの提供手順を説明する図である。図には、図２で示した携帯電話１０および航空機２０が示してある。また、携帯電話１０の所有者である利用者７１および航空事業者窓口７２が示してある。 FIG. 5 is a diagram for explaining a procedure for providing a video / music distribution service in an aircraft using a mobile phone. In the figure, the mobile phone 10 and the aircraft 20 shown in FIG. 2 are shown. In addition, a user 71 who is the owner of the mobile phone 10 and an airline operator window 72 are shown.
　ステップＳ１に示すように、利用者７１は、航空事業者窓口７２にて搭乗手続きを行う。利用者７１は、航空機２０内で映像／音楽配信サービスの提供を受ける場合、航空事業者窓口７２でその旨を通知する。 As shown in step S <b> 1, the user 71 performs boarding procedures at the airline business counter 72. When the user 71 is provided with the video / music distribution service in the aircraft 20, the user 71 notifies the air carrier window 72 to that effect.
　ステップＳ２に示すように、航空事業者窓口７２は、携帯電話１０にコマンドを送信し、携帯電話１０の端末設定を行う。例えば、航空事業者窓口７２は、利用者７１が映像／音楽配信サービスを航空機２０内で受けることができるように切替え回路４０を設定し、また、モデム３８のモデム設定を行う。また、航空機２０内で携帯電話１０から電磁波が発生しないように、ＲＦ部４３をオフするように設定する。 As shown in step S2, the airline provider window 72 transmits a command to the mobile phone 10 to set the terminal of the mobile phone 10. For example, the airline provider window 72 sets the switching circuit 40 so that the user 71 can receive the video / music distribution service in the aircraft 20 and sets the modem 38 for the modem 38. Further, the RF unit 43 is set to be turned off so that the mobile phone 10 does not generate electromagnetic waves in the aircraft 20.
　なお、航空事業者窓口７２は、携帯電話１０にコマンドを送信する際、携帯電話１０がコマンドを受付けるように、利用者７１に認証処理を行ってもらう必要がある。
　また、携帯電話１０は、コマンドに含まれるフィルタ情報と、第三者設定情報メモリ３６に予め記憶されているフィルタ情報とが一致する場合にのみ、コマンドを受付ける。フィルタ情報は、航空事業者窓口７２のみが知っており、利用者７１は自由にコマンドを入力できないようになっている。 Note that when the airline provider window 72 transmits a command to the mobile phone 10, the user 71 needs to perform an authentication process so that the mobile phone 10 receives the command.
Further, the mobile phone 10 accepts a command only when the filter information included in the command matches the filter information stored in advance in the third party setting information memory 36. The filter information is known only by the airline operator window 72, so that the user 71 cannot freely enter commands.
　また、コマンド入力は、航空事業者窓口７２が携帯電話１０のキーパッド３１ｃから直接行うようにしてもよく、また、航空事業者窓口７２のＩＣチップ読み取り装置に、携帯電話１０をかざして、非接触ＩＣチップ３１ｂから入力するようにしてもよい。また、ＱＲ（Quick Response code）コードなどによって、カメラ３１ａを介して入力するようにしてもよい。 Also, the command input may be performed directly by the airline operator window 72 from the keypad 31c of the mobile phone 10, or the mobile phone 10 is held over the IC chip reading device of the airline operator window 72, and the command input is not performed. Input may be made from the contact IC chip 31b. Further, it may be input via the camera 31a by a QR (Quick Response Code) code or the like.
　また、航空事業者窓口７２は、映像や音楽を再生するためのアプリケーションを携帯電話１０にダウンロードし、または配布するようにしてもよい。
　ステップＳ３に示すように、利用者７１は、航空機２０に搭乗する。利用者７１は、図に示すように、携帯電話１０を座席に設けられているジャック２３に接続する。例えば、音声信号入出力装置３９をジャック２３に接続する。 Further, the airline provider window 72 may download or distribute an application for playing back video and music to the mobile phone 10.
As shown in step S <b> 3, the user 71 gets on the aircraft 20. As shown in the figure, the user 71 connects the mobile phone 10 to the jack 23 provided in the seat. For example, the audio signal input / output device 39 is connected to the jack 23.
　ステップＳ４に示すように、利用者７１は、選択スイッチ２２のチャンネル操作によって、見たい映像を選択する。なお、音楽サービスを選択したい場合には、従来どおり、ジャック２３にヘッドホンのプラグを接続し、希望する音楽サービスを選択すればよい。 As shown in step S4, the user 71 selects a desired video by operating the channel of the selection switch 22. In order to select a music service, a headphone plug may be connected to the jack 23 and a desired music service may be selected as before.
　ステップＳ５に示すように、映像／音楽配信装置２１は、携帯電話１０に対し、選択された映像データのデータ配信を行う。映像／音楽配信装置２１は、データ配信を音声帯域の信号で行う。 As shown in step S5, the video / music distribution device 21 distributes the selected video data to the mobile phone 10. The video / music distribution device 21 performs data distribution using signals in the audio band.
　ステップＳ６に示すように、携帯電話１０は、配信されたデータのデコードを行う。携帯電話１０は、音声帯域の信号をデジタル信号に変換する。
　ステップＳ７に示すように、利用者７１は、デコードされた配信データを視聴する。なお、配信データが映画のデータであった場合、その映画は、携帯電話１０のＬＣＤ４６に表示される。 As shown in step S6, the mobile phone 10 decodes the distributed data. The mobile phone 10 converts a voice band signal into a digital signal.
As shown in step S7, the user 71 views the decoded distribution data. If the distribution data is movie data, the movie is displayed on the LCD 46 of the mobile phone 10.
　ステップＳ８に示すように、利用者７１は、目的地に到着したとする。
　ステップＳ９に示すように、利用者７１は、航空事業者窓口７２にて、携帯電話１０の無線機能を使えるように、設定解除をしてもらう。例えば、航空事業者窓口７２は、コマンドで、音声通話が可能となるように切替え回路４０を設定し、無線通信が可能となるようにＲＦ部４３をオン設定する。 As shown in step S8, it is assumed that the user 71 has arrived at the destination.
As shown in step S <b> 9, the user 71 cancels the setting so that the wireless function of the mobile phone 10 can be used at the airline provider window 72. For example, the airline operator window 72 sets the switching circuit 40 so that voice communication is possible and turns on the RF unit 43 so that wireless communication is possible.
　図６、図７、および図８は、映像／音楽配信サービスの提供手順を示したシーケンス図である。図には、利用者７１と、携帯電話１０の利用者認証部３２、第三者制御部３０ａ、第三者設定情報メモリ３６、およびモデム制御部３７と、航空事業者窓口７２の搭乗手続き装置および搭乗者管理部と、航空機２０内の映像／音楽配信装置２１（配信装置）とのシーケンスが示してある。 FIG. 6, FIG. 7, and FIG. 8 are sequence diagrams showing procedures for providing a video / music distribution service. The figure shows a user 71, a user authentication unit 32 of the mobile phone 10, a third party control unit 30 a, a third party setting information memory 36, a modem control unit 37, and a boarding procedure apparatus for an airline operator window 72. The sequence of the passenger management unit and the video / music distribution device 21 (distribution device) in the aircraft 20 is shown.
　ステップＳ２１において、利用者７１は、航空事業者窓口７２にて、搭乗手続きを行い、航空機２０内での映像／音楽配信サービスの利用依頼を行う。
　ステップＳ２２において、航空事業者窓口７２は、搭乗手続き装置にて、搭乗者の情報を管理する搭乗者管理部に対し、利用者７１の利用登録を行う。 In step S <b> 21, the user 71 performs a boarding procedure at the airline provider window 72 and requests use of the video / music distribution service in the aircraft 20.
In step S22, the airline operator window 72 registers the use of the user 71 with the passenger management unit that manages the information of the passenger at the boarding procedure apparatus.
　ステップＳ２３において、搭乗者管理部は、搭乗手続き装置に対し、登録応答を返す。
　ステップＳ２４において、航空事業者窓口７２は、携帯電話１０が航空事業者窓口７２のコマンドを受付けるように、利用者７１に対し、認証要求を行う。 In step S23, the passenger management unit returns a registration response to the boarding procedure apparatus.
In step S <b> 24, the airline operator window 72 makes an authentication request to the user 71 so that the mobile phone 10 receives the command from the airline company window 72.
　ステップＳ２５において、利用者７１は、航空事業者窓口７２からの認証要求を受けて、携帯電話１０の利用者認証部３２に対し、認証を行う。例えば、利用者７１は、所定のパスワードを携帯電話１０に入力する。 In step S <b> 25, the user 71 authenticates the user authentication unit 32 of the mobile phone 10 in response to an authentication request from the airline business counter 72. For example, the user 71 inputs a predetermined password into the mobile phone 10.
　ステップＳ２６において、携帯電話１０の利用者認証部３２は、利用者７１が適正な利用者であると判断した場合、入力装置３１から、航空事業者窓口７２のコマンドを受付けるように、制御切替え部３３を制御する。すなわち、利用者認証部３２は、入力装置３１から入力されるコマンドが、第三者認証登録部３０ａａに出力されるように、制御切替え部３３を制御する。 In step S26, when the user authentication unit 32 of the mobile phone 10 determines that the user 71 is an appropriate user, the control switching unit is configured to receive the command of the airline operator window 72 from the input device 31. 33 is controlled. That is, the user authentication unit 32 controls the control switching unit 33 so that a command input from the input device 31 is output to the third party authentication registration unit 30aa.
　ステップＳ２７において、利用者７１は、携帯電話１０にコマンドを入力するよう、航空事業者窓口７２に要求する。例えば、ＩＣチップ読み取り装置に携帯電話１０をかざして、コマンド入力するように要求する。なお、携帯電話１０をＩＣチップ読み取り装置にかざすのは、利用者７１が行ってもよいし、航空事業者窓口７２が行ってもよい。 In step S27, the user 71 requests the airline operator window 72 to input a command to the mobile phone 10. For example, the mobile phone 10 is held over the IC chip reader and a command is input. Note that the user 71 or the airline operator window 72 may hold the mobile phone 10 over the IC chip reader.
　ステップＳ２８において、携帯電話１０の第三者制御部３０ａは、ＩＣチップ読み取り装置を介して、航空事業者窓口７２の搭乗手続き装置に対し、コマンド送信要求を行う。
　ステップＳ２９において、搭乗手続き装置は、コマンド送信要求してきた利用者７１が、搭乗手続きを行い、映像／音楽配信サービスの提供を受ける手続きを行った者か、搭乗者管理部に対し、認証依頼を行う。 In step S28, the third party control unit 30a of the mobile phone 10 issues a command transmission request to the boarding procedure device at the airline business counter 72 via the IC chip reader.
In step S29, the boarding procedure apparatus sends an authentication request to the passenger management section, whether the user 71 who has requested the command transmission has performed the boarding procedure and received the provision of the video / music distribution service. Do.
　ステップＳ３０において、搭乗者管理部は、利用者７１の認証処理を行う。なお、利用者７１は、ステップＳ２１，Ｓ２２で、搭乗手続きおよび映像／音楽配信サービスの利用手続を行っており、認証は認められる。 In step S30, the passenger management unit performs an authentication process for the user 71. Note that the user 71 has performed the boarding procedure and the video / music distribution service usage procedure in steps S21 and S22, and authentication is permitted.
　ステップＳ３１において、搭乗手続き装置は、ＩＣチップ読み取り装置を介して、携帯電話１０にコマンドを送信する。コマンドには、図４で説明した情報が含まれている。
　ステップＳ３２において、第三者制御部３０ａの第三者認証登録部３０ａａは、コマンドに含まれるフィルタ情報に基づいて、コマンドが適正なコマンドであるか否か判断する。第三者認証登録部３０ａａは、フィルタ情報が適正であると判断した場合、入力されたコマンドを受付ける。第三者制御部３０ａは、受付けられたコマンドのＲＦ状態制御情報５４に基づいて、ＲＦ部４３に電源が供給されないよう、ＲＦ停止制御部３４を制御する。また、第三者制御部３０ａは、受付けられたコマンドの切替え回路制御情報５３に基づいて、音声信号入出力装置３９から入力される音声帯域の信号の出力先を、モデム３８に切替えるように、切替え回路４０を制御する。 In step S31, the boarding procedure device transmits a command to the mobile phone 10 via the IC chip reader. The command includes the information described with reference to FIG.
In step S32, the third party authentication registration unit 30aa of the third party control unit 30a determines whether or not the command is an appropriate command based on the filter information included in the command. If the third party authentication registration unit 30aa determines that the filter information is appropriate, the third party authentication registration unit 30aa accepts the input command. The third party control unit 30 a controls the RF stop control unit 34 so that power is not supplied to the RF unit 43 based on the RF state control information 54 of the accepted command. Further, the third party control unit 30 a switches the output destination of the audio band signal input from the audio signal input / output device 39 to the modem 38 based on the received command switching circuit control information 53. The switching circuit 40 is controlled.
　ステップＳ３３において、第三者制御部３０ａは、コマンドに含まれている設定情報５７～５９を第三者設定情報メモリ３６に格納する。例えば、コマンドに含まれているモデムの通信速度、圧縮方法、誤り訂正方法などを格納する。 In step S33, the third party control unit 30a stores the setting information 57 to 59 included in the command in the third party setting information memory 36. For example, the modem communication speed, compression method, error correction method, and the like included in the command are stored.
　ステップＳ３４において、モデム制御部３７は、第三者設定情報メモリ３６に格納されている設定情報を読み出し、モデム３８の制御を行う。
　ステップＳ３５において、第三者制御部３０ａは、ＩＣチップ読み取り装置を介して、航空事業者窓口７２の搭乗手続き装置に対し、設定完了通知を行う。 In step S <b> 34, the modem control unit 37 reads the setting information stored in the third party setting information memory 36 and controls the modem 38.
In step S35, the third party control unit 30a sends a setting completion notification to the boarding procedure device of the airline business counter 72 via the IC chip reader.
　ステップＳ３６において、搭乗手続き装置は、ＩＣチップ読み取り装置を介して、第三者制御部３０ａに対し、設定完了通知を受信した旨の応答を送信する。
　ステップＳ３７において、搭乗手続き装置は、搭乗者管理部に携帯電話１０に設定した登録情報を送信する。 In step S36, the boarding procedure device transmits a response indicating that the setting completion notification has been received to the third party control unit 30a via the IC chip reading device.
In step S37, the boarding procedure apparatus transmits the registration information set in the mobile phone 10 to the passenger management unit.
　ステップＳ３８において、航空事業者窓口７２は、利用者７１に対し、設定完了通知を行う。なお、ここで、利用者７１は、航空機２０に搭乗したとする。
　ステップＳ３９において、利用者７１は、携帯電話１０を、航空機２０内の映像／音楽配信装置２１に接続する。 In step S <b> 38, the airline operator window 72 sends a setting completion notification to the user 71. Here, it is assumed that the user 71 has boarded the aircraft 20.
In step S <b> 39, the user 71 connects the mobile phone 10 to the video / music distribution device 21 in the aircraft 20.
　ステップＳ４０において、利用者７１は、映像／音楽配信装置２１に対して選択スイッチ２２の操作により所望のチャンネルを選択する。
　ステップＳ４１において、映像／音楽配信装置２１は、音声帯域の信号により、映像データまたは音楽データを携帯電話１０に配信する。 In step S <b> 40, the user 71 selects a desired channel for the video / music distribution apparatus 21 by operating the selection switch 22.
In step S <b> 41, the video / music distribution device 21 distributes video data or music data to the mobile phone 10 by an audio band signal.
　ステップＳ４２において、モデム３８は、受信した音声帯域の信号をデジタル信号に変換する。第三者制御部３０ａは、モデム３８でデジタル信号に変換されたデータのデコード処理を行い、ＬＣＤ４６に表示する。また、音声をスピーカ３９ａから出力する。 In step S42, the modem 38 converts the received voice band signal into a digital signal. The third party control unit 30 a decodes the data converted into a digital signal by the modem 38 and displays it on the LCD 46. Also, sound is output from the speaker 39a.
　ステップＳ４３において、利用者７１は、ＬＣＤ４６を介し、映像サービスを受ける。また、スピーカ３９ａから音楽サービスを受ける。
　ステップＳ４４において、利用者７１は、ＲＦ部４３をオンするために、例えば、キーパッド３１ｃから、コマンドを入力したとする。 In step S <b> 43, the user 71 receives a video service via the LCD 46. In addition, a music service is received from the speaker 39a.
In step S44, it is assumed that the user 71 inputs a command from, for example, the keypad 31c to turn on the RF unit 43.
　ステップＳ４５において、第三者制御部３０ａの第三者認証登録部３０ａａは、コマンドのフィルタ情報が不適切であると判断する。利用者７１は、コマンドのフィルタ情報を知らず、航空事業者窓口７２しか知らないからである。これにより、利用者７１は、航空機２０内で勝手にＲＦ部４３をオンして無線通信を行うことができない。 In step S45, the third party authentication registration unit 30aa of the third party control unit 30a determines that the filter information of the command is inappropriate. This is because the user 71 does not know the filter information of the command, but only the airline business counter 72. Accordingly, the user 71 cannot turn on the RF unit 43 without permission in the aircraft 20 to perform wireless communication.
　ステップＳ４６において、第三者認証登録部３０ａａは、例えば、ＬＣＤ４６において、コマンドを受付けることができない旨を表示し、利用者７１に通知する。
　ステップＳ４７において、航空機２０は、目的地に到着し、利用者７１は、携帯電話１０を映像／音楽配信装置２１から取り外したとする。 In step S46, the third-party authentication registration unit 30aa displays, for example, on the LCD 46 that the command cannot be accepted and notifies the user 71.
In step S <b> 47, it is assumed that the aircraft 20 has arrived at the destination and the user 71 has detached the mobile phone 10 from the video / music distribution device 21.
　ステップＳ４８において、利用者７１は、航空事業者窓口７２にて、サービス解除の要求を行う。すなわち、利用者７１は、携帯電話１０の無線通信を行えるように要求する。
　ステップＳ４９において、搭乗手続き装置は、映像／音楽配信サービスの提供を受ける手続きを行った者か、搭乗者管理部に対し、認証依頼を行う。 In step S <b> 48, the user 71 issues a service cancellation request at the airline operator window 72. That is, the user 71 requests that the mobile phone 10 perform wireless communication.
In step S49, the boarding procedure apparatus issues an authentication request to the person who has performed the procedure for receiving provision of the video / music distribution service or to the passenger management unit.
　ステップＳ５０において、搭乗者管理部は、利用者７１の認証処理を行う。なお、利用者７１は、ステップＳ２１，Ｓ２２で、搭乗手続きおよび映像／音楽配信サービスの利用手続きを行っており、認証は認められる。 In step S50, the passenger management unit performs an authentication process for the user 71. Note that the user 71 has performed the boarding procedure and the use procedure of the video / music distribution service in steps S21 and S22, and authentication is permitted.
　ステップＳ５１において、航空事業者窓口７２は、利用者７１の携帯電話１０に対し、設定解除を行うためのコマンドを送信する。
　ステップＳ５２において、第三者制御部３０ａは、コマンドに基づいて、切替え回路４０およびＲＦ停止制御部３４の制御を行う。例えば、第三者制御部３０ａは、音声信号入出力装置３９から出力される信号が音声インターフェース部４１に出力されるように、切替え回路４０を制御する。また、ＲＦ部４３に電源が供給されるように、ＲＦ停止制御部３４を制御する。 In step S <b> 51, the airline provider window 72 transmits a command for canceling the setting to the mobile phone 10 of the user 71.
In step S52, the third party control unit 30a controls the switching circuit 40 and the RF stop control unit 34 based on the command. For example, the third party control unit 30 a controls the switching circuit 40 so that a signal output from the audio signal input / output device 39 is output to the audio interface unit 41. In addition, the RF stop control unit 34 is controlled so that power is supplied to the RF unit 43.
　ステップＳ５３において、第三者制御部３０ａは、第三者設定情報メモリ３６に格納されている設定情報をクリアする。
　このように、携帯電話１０は、電磁波を発生するＲＦ部４３をオン／オフする機能を有し、音声帯域の信号によって、映像／音楽配信サービスを航空機２０内で受けることができるようにした。これにより、電磁波が制限される航空機２０内でも、携帯電話１０を使用することができる。 In step S53, the third party control unit 30a clears the setting information stored in the third party setting information memory 36.
As described above, the mobile phone 10 has a function of turning on / off the RF unit 43 that generates electromagnetic waves, and can receive the video / music distribution service in the aircraft 20 by a signal in the audio band. Accordingly, the mobile phone 10 can be used even in the aircraft 20 where electromagnetic waves are restricted.
　また、携帯電話１０の無線回路部分のオン／オフは、携帯電話１０の所有者が自由に設定することができないため、故意や過失により、電磁波が発生することがなく、航空機２０の安全性を保つことができる。 In addition, since the owner of the mobile phone 10 cannot set the wireless circuit portion of the mobile phone 10 on and off, electromagnetic waves are not generated due to intentional or negligence, and the safety of the aircraft 20 can be improved. Can keep.
　なお、携帯電話１０の接続端子３９ｃは、ステレオ放送の音声帯域の信号を送受信するように構成してもよい。そして、モデム３８は、２つの音声帯域の信号をアナログ－デジタル変換およびデジタル－アナログ変換するようにする。これにより、送受信するデータの帯域を２倍にすることができる。 Note that the connection terminal 39c of the mobile phone 10 may be configured to transmit and receive signals in the audio band of stereo broadcasting. The modem 38 performs analog-to-digital conversion and digital-to-analog conversion on the signals of the two voice bands. As a result, the bandwidth of data to be transmitted / received can be doubled.
　また、携帯電話１０にモデム３８を複数個搭載し、それぞれにおいて、データの送受信を行うようにしてもよい。これによっても、送受信するデータの帯域を広げることができる。 Alternatively, a plurality of modems 38 may be mounted on the mobile phone 10 and each may transmit and receive data. This can also widen the bandwidth of data to be transmitted / received.
　また、第三者設定情報メモリ３６に記憶されているフィルタ情報は、設定、変更、および消去することができるようにしてもよい。フィルタ情報の設定、変更、および消去は、パスワードによって行うことができ、パスワードは、例えば、予めメモリ４４に記憶しておく。なお、パスワードは、携帯電話１０の利用者以外である航空事業者のみが知っているものとし、航空事業者のみが設定できるものとする。 Further, the filter information stored in the third party setting information memory 36 may be set, changed, and deleted. Setting, changing, and erasing of filter information can be performed with a password, and the password is stored in the memory 44 in advance, for example. It is assumed that the password is known only to the airliner other than the user of the mobile phone 10 and can be set only by the airliner.
　第三者制御部３０ａは、フィルタ情報の設定、変更、および消去の要求があった場合、入力装置３１から入力されるパスワードと、メモリ４４に記憶されているパスワードとを比較し、一致した場合のみ、第三者設定情報メモリ３６のフィルタ情報の設定、変更、および消去を受付ける。 When there is a request for setting, changing, and deleting the filter information, the third party control unit 30a compares the password input from the input device 31 with the password stored in the memory 44. Only the setting, change and deletion of the filter information in the third party setting information memory 36 are accepted.
　フィルタ情報を消去した状態は、例えば、フィルタ情報が全て‘０’である場合とする。すなわち、第三者設定情報メモリ３６のフィルタ情報が全て‘０’の場合、フィルタ情報は、消去されている状態となる。この場合、携帯電話１０の利用者でも、コマンド入力することができる。すなわち、コマンドのフィルタ情報を‘０’にすれば、誰でも、携帯電話１０のＲＦ４３の設定やモデム設定を自由に行うことができる。 The state in which the filter information is deleted is, for example, a case where all the filter information is “0”. That is, when all the filter information in the third party setting information memory 36 is “0”, the filter information is in an erased state. In this case, even the user of the mobile phone 10 can input a command. In other words, if the filter information of the command is set to “0”, anyone can freely set the RF 43 and the modem of the mobile phone 10.
　また、利用者が航空機２０に搭乗する際、航空事業者は、フィルタ情報とパスワードとを携帯電話１０に設定して、コマンド設定を行うようにし、利用者が目的地に着いた場合、航空事業者は、利用者にパスワードのみを通知することもできる。この場合、利用者は、通知されたパスワードでフィルタ情報を消去すれば、携帯電話１０の無線機能を解除することができる。もちろん、携帯電話１０の利用者が再度航空機２０に搭乗するときは、航空事業者は、別のフィルタ情報とパスワードとを携帯電話１０に設定し、コマンド設定することになる。 Further, when the user boardes the aircraft 20, the airline operator sets the filter information and the password in the mobile phone 10 to perform command setting. When the user arrives at the destination, the airline operator The user can also notify the user only of the password. In this case, the user can cancel the wireless function of the mobile phone 10 by deleting the filter information with the notified password. Of course, when the user of the mobile phone 10 gets on the aircraft 20 again, the airliner sets another filter information and password in the mobile phone 10 and sets a command.
　次に、本発明の第２の実施の形態を図面を参照して詳細に説明する。第２の実施の形態では、携帯電話は、航空機から緊急信号を受信することができる。
　図９は、第２の実施の形態に係る操作コマンドの一例を示した図である。図の操作コマンドは、図４の操作コマンドに対し、設定情報８１，８２が追加されているところが異なる。図４と同じものには同じ符号を付し、その説明を省略する。 Next, a second embodiment of the present invention will be described in detail with reference to the drawings. In the second embodiment, the mobile phone can receive an emergency signal from the aircraft.
FIG. 9 is a diagram illustrating an example of an operation command according to the second embodiment. The operation command in the figure is different from the operation command in FIG. 4 in that setting information 81 and 82 is added. The same components as those in FIG. 4 are denoted by the same reference numerals and description thereof is omitted.
　コマンドの設定情報８１には、どのような信号が緊急信号１であるかを示す情報が格納される。コマンドの設定情報８２には、どのような信号が緊急信号２であるかを示す情報が格納される。 The command setting information 81 stores information indicating what signal is the emergency signal 1. Information indicating what signal is the emergency signal 2 is stored in the command setting information 82.
　Ｖシリーズ勧告モデムの搬送周波数は、２ｋＨｚ以下である。そこで、例えば、４ｋＨｚと６ｋＨｚの正弦信号が２秒以上継続して検出した場合を緊急信号１とし、５ｋＨｚと７ｋＨｚの正弦信号が２秒以上継続した場合を緊急信号２とする。コマンドの設定情報８１，８２には、緊急信号１，２を示す前述の情報が格納される。 The carrier frequency of the V series recommended modem is 2 kHz or less. Thus, for example, an emergency signal 1 is a case where sine signals of 4 kHz and 6 kHz are continuously detected for 2 seconds or more, and an emergency signal 2 is a case where sine signals of 5 kHz and 7 kHz are continuously detected for 2 seconds or more. The command setting information 81 and 82 stores the above-described information indicating the emergency signals 1 and 2.
　なお、設定情報８１，８２は、図３で説明した第三者設定情報メモリ３６に記憶される。モデム制御部３７は、第三者設定情報メモリ３６に記憶された緊急信号１，２の情報をモデム３８に通知する。 The setting information 81 and 82 is stored in the third party setting information memory 36 described with reference to FIG. The modem control unit 37 notifies the modem 38 of information on the emergency signals 1 and 2 stored in the third party setting information memory 36.
　モデム３８は、第２の実施の形態では、緊急信号抽出部を有する。モデム３８の緊急信号抽出部は、モデム制御部３７から通知される緊急信号１，２の情報に基づき、音声信号入出力装置３９から出力される信号の緊急信号を抽出する。モデム３８は、緊急信号１，２を抽出すると、その旨を制御部３０に通知する。 The modem 38 has an emergency signal extraction unit in the second embodiment. The emergency signal extraction unit of the modem 38 extracts the emergency signal of the signal output from the audio signal input / output device 39 based on the information of the emergency signals 1 and 2 notified from the modem control unit 37. When the modem 38 extracts the emergency signals 1 and 2, the modem 38 notifies the control unit 30 to that effect.
　例えば、音声信号入出力装置３９から出力される信号が４ｋＨｚと６ｋＨｚの正弦信号であり、２秒以上継続した場合には、モデム３８は、緊急信号１を抽出する。また、音声信号入出力装置３９から出力される信号が５ｋＨｚと７ｋＨｚの正弦信号であり、２秒以上継続した場合には、モデム３８は、緊急信号２を抽出する。モデム３８は、緊急信号１，２を抽出すると、その旨を制御部３０に通知する。 For example, when the signal output from the audio signal input / output device 39 is a sine signal of 4 kHz and 6 kHz and continues for 2 seconds or more, the modem 38 extracts the emergency signal 1. When the signal output from the audio signal input / output device 39 is a sine signal of 5 kHz and 7 kHz and continues for 2 seconds or longer, the modem 38 extracts the emergency signal 2. When the modem 38 extracts the emergency signals 1 and 2, the modem 38 notifies the control unit 30 to that effect.
　制御部３０は、モデム３８から緊急信号１，２を受信した旨を通知すると、所定の制御を行う。
　例えば、航空機２０は、乗客の携帯電話１０の電源をオフしてもらいたい場合、映像／音楽配信装置２１から緊急信号１を流す。制御部３０は、モデム３８から緊急信号１を受信した旨の通知を受けると、ＬＣＤ４６に携帯電話１０の電源をオフするように促す画面を表示する。 When notifying that the emergency signals 1 and 2 have been received from the modem 38, the control unit 30 performs predetermined control.
For example, the aircraft 20 sends the emergency signal 1 from the video / music distribution device 21 when the passenger's mobile phone 10 is desired to be turned off. When the control unit 30 receives a notification that the emergency signal 1 has been received from the modem 38, the control unit 30 displays a screen for prompting the mobile phone 10 to be turned off on the LCD 46.
　また、航空機２０は、携帯電話１０の電源を強制的にオフしたい場合、映像／音楽配信装置２１から緊急信号２を流す。制御部３０は、モデム３８から緊急信号２を受信した旨の通知を受けると、電源制御部４５を制御して、携帯電話１０の全体の電源を強制的にオフする。 In addition, the aircraft 20 sends the emergency signal 2 from the video / music distribution device 21 when the mobile phone 10 is forced to be turned off. Upon receiving notification that the emergency signal 2 has been received from the modem 38, the control unit 30 controls the power supply control unit 45 to forcibly turn off the power supply of the mobile phone 10.
　図１０は、映像／音楽配信サービスの提供手順を示したシーケンス図である。図１０のシーケンス図には、図６、図７、および図８のシーケンス図と同様に、利用者７１と、携帯電話１０の利用者認証部３２、第三者制御部３０ａ、第三者設定情報メモリ３６、およびモデム制御部３７と、航空事業者窓口７２の搭乗手続き装置および搭乗者管理部と、航空機２０内の映像／音楽配信装置２１（配信装置）とのシーケンスが示してある。 FIG. 10 is a sequence diagram showing a procedure for providing a video / music distribution service. In the sequence diagram of FIG. 10, as in the sequence diagrams of FIGS. 6, 7, and 8, the user 71, the user authentication unit 32 of the mobile phone 10, the third party control unit 30 a, third party setting The sequence of the information memory 36, the modem control unit 37, the boarding procedure device and passenger management unit of the airline operator window 72, and the video / music distribution device 21 (distribution device) in the aircraft 20 is shown.
　なお、図１０のシーケンスでは、第三者制御部３０ａは、航空事業者窓口７２から緊急信号の情報を有するコマンドを受信し、第三者設定情報メモリ３６に格納しているとする。例えば、図６で説明したステップＳ３１のコマンド送信で、緊急信号の情報を有するコマンドを受信する。 In the sequence of FIG. 10, it is assumed that the third party control unit 30 a receives a command having emergency signal information from the airline operator window 72 and stores it in the third party setting information memory 36. For example, the command having the emergency signal information is received by the command transmission in step S31 described in FIG.
　また、図１０のシーケンスでは、図６、図７、および図８のシーケンスに対し、映像／音楽配信装置２１からサービス配信を受けているときに、緊急信号を受信するところが異なる。従って、図１０のシーケンスでは、利用者７１は、航空機２０に搭乗し、映像／音楽配信装置２１から映像／音楽の配信サービスを受けているとする。その他のシーケンスは、図６、図７、および図８と同様である。 Further, the sequence of FIG. 10 differs from the sequence of FIGS. 6, 7, and 8 in that an emergency signal is received when receiving service delivery from the video / music delivery device 21. Therefore, in the sequence of FIG. 10, it is assumed that the user 71 is on the aircraft 20 and receives a video / music distribution service from the video / music distribution device 21. Other sequences are the same as those in FIGS. 6, 7, and 8.
　ステップＳ６１において、映像／音楽配信装置２１は、緊急信号を配信する。映像／音楽配信装置２１は、例えば、航空機２０の離着陸時に緊急信号を配信する。航空機２０の離着陸時は、計器類に影響をおよぼさないように電子機器の電源をオフする必要があるからである。 In step S61, the video / music distribution device 21 distributes an emergency signal. The video / music distribution device 21 distributes an emergency signal when the aircraft 20 takes off and landing, for example. This is because when the aircraft 20 takes off and landing, it is necessary to turn off the power of the electronic device so as not to affect the instruments.
　ステップＳ６２において、モデム３８は、緊急信号を抽出し、その旨を制御部３０に通知する。制御部３０は、モデム３８からの緊急信号の受信通知を受けて、緊急信号の受信処理を行う。例えば、緊急信号の種類に応じて、ＬＣＤ４６に携帯電話１０の電源をオフするように表示し、または、電源制御部４５を制御して、携帯電話１０の電源を強制的にオフするようにする。 In step S62, the modem 38 extracts an emergency signal and notifies the control unit 30 accordingly. Upon receiving the emergency signal reception notification from the modem 38, the control unit 30 performs emergency signal reception processing. For example, according to the type of emergency signal, the LCD 46 is displayed to turn off the power of the mobile phone 10 or the power control unit 45 is controlled to forcibly turn off the power of the mobile phone 10. .
　ステップＳ６３において、利用者７１は、例えば、ＬＣＤ４６の表示などによって、緊急信号が発信されたことを認識する。
　このように、携帯電話１０は、緊急信号を受信することができるようにした。これにより、携帯電話１０は、受信した緊急信号の種類に応じて、動作モードを切替えることができ、例えば、利用者７１に電源オフの通知をしたり、強制的に電源をオフしたりすることができる。 In step S63, the user 71 recognizes that an emergency signal has been transmitted, for example, by displaying on the LCD 46.
As described above, the mobile phone 10 can receive the emergency signal. Thereby, the mobile phone 10 can switch the operation mode according to the type of the received emergency signal. For example, the mobile phone 10 notifies the user 71 of power off or forcibly turns off the power. Can do.
　次に、本発明の第３の実施の形態を図面を参照して詳細に説明する。第１の実施の形態および第２の実施の形態では、携帯電話は、航空機に用意されているオーディオサービス用の設備を利用し、映像／音楽配信サービスおよび緊急信号を受信していたが、第３の実施の形態では、双方向のネットワーク接続サービスで映像／音楽および緊急信号を受信する。 Next, a third embodiment of the present invention will be described in detail with reference to the drawings. In the first embodiment and the second embodiment, the mobile phone uses the audio service equipment prepared in the aircraft to receive the video / music distribution service and the emergency signal. In the third embodiment, video / music and an emergency signal are received by a bidirectional network connection service.
　図１１は、第３の実施の形態に係る携帯電話を適用したシステム構成例を示した図である。図には、携帯電話１０，１０ａ，１０ｂ、航空機１００、地上局１１０、およびネットワーク１２０が示してある。また、利用者７１，７１ａ，７１ｂおよび航空事業者窓口７２が示してある。 FIG. 11 is a diagram illustrating an example of a system configuration to which the mobile phone according to the third embodiment is applied. In the figure, mobile phones 10, 10a, 10b, aircraft 100, ground station 110, and network 120 are shown. In addition, users 71, 71 a, 71 b and an air carrier window 72 are shown.
　図において、利用者７１は、携帯電話１０の所有者とする。利用者７１ａは、携帯電話１０ａの所有者とする。利用者７１ｂは、携帯電話１０ｂの所有者とする。
　航空機１００は、無線通信装置１０１およびＬＡＮ設備１０２を有している。無線通信装置１０１は、地上局１１０と無線通信を行う。 In the figure, a user 71 is assumed to be an owner of the mobile phone 10. The user 71a is assumed to be the owner of the mobile phone 10a. The user 71b is assumed to be the owner of the mobile phone 10b.
The aircraft 100 includes a wireless communication device 101 and a LAN facility 102. The wireless communication device 101 performs wireless communication with the ground station 110.
　ＬＡＮ設備１０２は、モデム接続が可能なＬＡＮ設備である。すなわち、携帯電話１０，１０ａ，１０ｂは、ＬＡＮ設備１０２にモデム接続することにより、航空機１００内でＬＡＮサービスを受けることができる。 The LAN facility 102 is a LAN facility that can be connected to a modem. That is, the cellular phones 10, 10 a, and 10 b can receive a LAN service in the aircraft 100 by connecting to the LAN facility 102 through a modem.
　また、ＬＡＮ設備１０２は、無線通信装置１０１と接続されており、例えば、インターネットであるネットワーク１２０と接続された地上局１１０と無線通信することができる。すなわち、携帯電話１０，１０ａ，１０ｂは、地上のネットワーク１２０にアクセスすることができる。 Further, the LAN facility 102 is connected to the wireless communication apparatus 101, and can wirelessly communicate with the ground station 110 connected to the network 120, which is the Internet, for example. That is, the mobile phones 10, 10 a, 10 b can access the ground network 120.
　ＬＡＮ設備１０２は、図示していないが、例えば、機内サービス用サーバ、ＲＡＳ（Remote Access Server）、ＰＢＸ（Private Branch eXchange）、およびルータを有している。 Although not shown, the LAN facility 102 includes, for example, an in-flight service server, a RAS (Remote Access Server), a PBX (Private Branch echange), and a router.
