　近年の通信トラヒックの増加は著しいものがあるが、それに対応して通信設備の容量を増加することは容易ではない。そのため、既存の設備を有効利用して通信の品質を担保するためのさまざまな手法が検討されている。 　There has been a significant increase in communication traffic in recent years, but it is not easy to increase the capacity of communication equipment accordingly. For this reason, various methods are being considered for making effective use of existing equipment and ensuring communication quality.
　例えば、特許文献１には、分散配置された複数の通信装置が形成する無線リンクの品質情報を他の通信装置に通知するリンク情報管理部と、品質情報に基づいて、各無線リンクの通信品質の変動を予測する回線品質予測部と、その予測結果に基づいて、発着通信装置間のトラヒックを伝送する経路を決定する経路制御部と、を備えるネットワーク制御装置が開示されている。この構成により、ネットワーク全体としての回線稼働率やスループットを向上させることができるとされている。 For example, Patent Document 1 discloses a network control device that includes a link information management unit that notifies other communication devices of quality information of wireless links formed by multiple distributed communication devices, a line quality prediction unit that predicts fluctuations in communication quality of each wireless link based on the quality information, and a route control unit that determines a route for transmitting traffic between originating and terminating communication devices based on the prediction results. This configuration is said to be capable of improving line availability and throughput for the entire network.
　また、特許文献２には、適応変調を用いた無線リンクについて、帯域の安定度を示す確率である帯域確率が所定の閾値よりも高い通信経路を優先的にネットワークに設定し、所定の閾値よりも帯域確率が低い通信経路に対して別の経路を準備する経路制御装置を有する経路制御システムが開示されている。これにより、高品質な通信を可能とすることができるとされている。 Patent Document 2 also discloses a route control system having a route control device that, for wireless links using adaptive modulation, preferentially sets in the network communication routes whose bandwidth probability, which is a probability indicating the stability of the bandwidth, is higher than a predetermined threshold, and prepares alternative routes for communication routes whose bandwidth probability is lower than the predetermined threshold. This is said to enable high-quality communications.

　〔例示的実施形態１〕
　本発明の第１の例示的実施形態について、図面を参照して詳細に説明する。本例示的実施形態は、後述する例示的実施形態の基本となる形態である。本例示的実施形態１に係る情報処理システム１は、送信装置が移動する場合でも、データを安定して送受信するための無線通信システムである。 [Example embodiment 1]
A first exemplary embodiment of the present invention will be described in detail with reference to the drawings. This exemplary embodiment is a basic form of the exemplary embodiments described later. An information processing system 1 according to the first exemplary embodiment is a wireless communication system for stably transmitting and receiving data even when a transmitting device moves.
　（情報処理システム１の構成）
　本例示的実施形態に係る情報処理システム１の構成について、図１を参照して説明する。図１は、情報処理システム１の構成を示すブロック図である。 (Configuration of Information Processing System 1)
The configuration of an information processing system 1 according to this exemplary embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing the configuration of the information processing system 1.
　情報処理システム１は、特定部１１と第１選択部１２とを備える。特定部１１は、複数の無線通信回線の各々において予測された経時的な帯域の変動範囲を示す予測帯域に応じて、移動体において取得されたデータを送信するための無線通信回線を選択する選択手法を特定する。データとは、一例として、静止画像及び／又は動画像を含む映像データ、又は音声データ等である。特定部１１は、請求の範囲に記載した特定手段の一形態である。 The information processing system 1 includes an identification unit 11 and a first selection unit 12. The identification unit 11 identifies a selection method for selecting a wireless communication line for transmitting data acquired by a mobile object according to a predicted bandwidth indicating a predicted range of bandwidth fluctuation over time in each of a plurality of wireless communication lines. The data is, for example, video data including still images and/or moving images, audio data, etc. The identification unit 11 is one form of the identification means described in the claims.
　本例示的実施形態において、無線通信回線とは、一例として、ＬＴＥ、４Ｇ、５Ｇ等のモバイル通信規格に基づき構成された回線（以下、代表して「ＬＴＥ回線」とも称する。）、Ｗｉ－Ｆｉ（登録商標）等の近距離無線通信規格に基づき構成された回線（以下、「Ｗｉ－Ｆｉ（登録商標）回線」とも称する。）、又は衛星通信回線等を含む任意の無線通信回線である。 In this exemplary embodiment, the wireless communication line may be, for example, a line configured based on a mobile communication standard such as LTE, 4G, or 5G (hereinafter also referred to as an "LTE line"), a line configured based on a short-range wireless communication standard such as Wi-Fi (registered trademark) (hereinafter also referred to as a "Wi-Fi (registered trademark) line"), or any wireless communication line including a satellite communication line, etc.
　また、帯域とは、無線通信回線の送信可能データ量であり、データのビットレート又はフレームレート等で表される。図示しない送信装置は移動するため、通信環境の経時的変化に伴い帯域が経時的に変動する。帯域がどのようにどの程度変動するかについては、公知の方法で予測することができる。予測された帯域の変動範囲を予測帯域と称する。選択手法の詳細については後述する。 The bandwidth is the amount of data that can be transmitted over a wireless communication line, and is expressed as the bit rate or frame rate of the data. Because a transmitting device (not shown) moves, the bandwidth fluctuates over time as the communication environment changes over time. How and to what extent the bandwidth will fluctuate can be predicted using known methods. The predicted range of bandwidth fluctuation is called the predicted bandwidth. The selection method will be described in detail later.
　第１選択部１２は、特定部１１によって特定された選択手法を参照して、複数の無線通信回線の中からデータを送信する１以上の無線通信回線を、データの送信中に選択する。データの送信中に無線通信回線を選択するとは、例えば具体的には、データを複数のパケットに分割し、最初のパケットを送信してから、最後のパケットを送信するまでの間に、複数の無線通信回線のうち送信に使用する無線通信回線を選択することである。送信装置１０は、第１選択部１２によって選択された無線通信回線を用いてデータを送信することができる。第１選択部１２は、請求の範囲に記載した第１選択手段の一形態である。 The first selection unit 12 refers to the selection method identified by the identification unit 11 and selects one or more wireless communication lines from among the multiple wireless communication lines to transmit data during data transmission. Selecting a wireless communication line during data transmission specifically means, for example, dividing data into multiple packets and selecting a wireless communication line to be used for transmission from among the multiple wireless communication lines during the period from when the first packet is transmitted to when the last packet is transmitted. The transmitting device 10 can transmit data using the wireless communication line selected by the first selection unit 12. The first selection unit 12 is one form of the first selection means described in the claims.
　なお、特定部１１と第１選択部１２は、１つの筐体に配置されている必要はなく、異なる筐体に分散配置され、互いに情報通信可能に接続されていてもよい。また、特定部１１と第１選択部１２は、少なくともその一部がクラウド上に配置されていてもよい。このように、各部又は各装置の少なくとも一部が分散して配置されていてもよく、あるいはクラウド上に配置されていてもよい点は、以降の例示的実施形態においても同様である。 The identification unit 11 and the first selection unit 12 do not have to be arranged in a single housing, but may be distributed in different housings and connected to each other so that they can communicate information. Also, at least a part of the identification unit 11 and the first selection unit 12 may be arranged on the cloud. In this way, at least a part of each part or device may be distributed or arranged on the cloud, and this also applies to the following exemplary embodiments.
　以上のように、本例示的実施形態に係る情報処理システム１においては、複数の無線通信回線の各々において予測された経時的な帯域の変動範囲を示す予測帯域に応じて、移動体において取得されたデータを送信するための無線通信回線を選択する選択手法を特定する特定手段と、特定された選択手法を参照して、複数の無線通信回線の中からデータを送信する１以上の無線通信回線を送信中に選択する選択手段と、を備えるという構成が採用されている。このため、本例示的実施形態に係る情報処理システム１によれば、通信中に通信状況が変化した場合でも無線通信の安定性を保つことができる、という効果が得られる。つまり、通信中に通信状況が変化した場合でも、データが途切れたり劣化したりすることなく送信することができる。 As described above, the information processing system 1 according to this exemplary embodiment is configured to include a specification means for specifying a selection method for selecting a wireless communication line for transmitting data acquired in a mobile body according to a predicted bandwidth indicating the predicted range of bandwidth fluctuation over time for each of a plurality of wireless communication lines, and a selection means for selecting, during transmission, one or more wireless communication lines from the plurality of wireless communication lines for transmitting data by referring to the specified selection method. Therefore, the information processing system 1 according to this exemplary embodiment has the effect of being able to maintain the stability of wireless communication even if the communication conditions change during communication. In other words, even if the communication conditions change during communication, data can be transmitted without interruption or degradation.
　（情報処理装置２の構成）
　次に、本例示的実施形態に係る情報処理装置２の構成について、図２を参照して説明する。図２は、情報処理装置２の構成を示すブロック図である。図示するように、情報処理装置２は、特定部１１と第１選択部１２を備える。 (Configuration of information processing device 2)
Next, the configuration of the information processing device 2 according to this exemplary embodiment will be described with reference to Fig. 2. Fig. 2 is a block diagram showing the configuration of the information processing device 2. As shown in the figure, the information processing device 2 includes an identification unit 11 and a first selection unit 12.
　特定部１１は、複数の無線通信回線の各々において予測された経時的な帯域の変動範囲を示す予測帯域に応じて、移動体において取得されたデータを送信するための無線通信回線を選択する選択手法を特定する。帯域、データ、無線通信回線等については、情報処理システム１の構成で説明したとおりである。また、第１選択部１２は、特定された選択手法を参照して、複数の無線通信回線の中からデータを送信する１以上の無線通信回線を送信中に選択する。選択手法の詳細については後述する。 The identification unit 11 identifies a selection method for selecting a wireless communication line for transmitting data acquired by the mobile body according to a predicted bandwidth indicating the predicted range of bandwidth fluctuation over time for each of the multiple wireless communication lines. The bandwidth, data, wireless communication line, etc. are as explained in the configuration of the information processing system 1. The first selection unit 12 also refers to the identified selection method and selects one or more wireless communication lines from the multiple wireless communication lines for transmitting data during transmission. The selection method will be described in detail later.
　以上のように、本例示的実施形態に係る情報処理装置２においては、複数の無線通信回線の各々において予測された経時的な帯域の変動範囲を示す予測帯域に応じて、移動体において取得されたデータを送信するための無線通信回線を選択する選択手法を特定する特定手段と、特定された選択手法を参照して、複数の無線通信回線の中からデータを送信する１以上の無線通信回線を送信中に選択する選択手段と、を備えるという構成が採用されている。このため、本例示的実施形態に係る情報処理システム１によれば、通信中に通信状況が変化した場合でも無線通信の安定性を保つことができる、という効果が得られる。 As described above, the information processing device 2 according to this exemplary embodiment is configured to include a specification means for specifying a selection method for selecting a wireless communication line for transmitting data acquired by a mobile body according to a predicted bandwidth indicating the predicted range of bandwidth fluctuation over time for each of a plurality of wireless communication lines, and a selection means for selecting, during transmission, one or more wireless communication lines for transmitting data from among the plurality of wireless communication lines by referring to the specified selection method. Therefore, the information processing system 1 according to this exemplary embodiment has the effect of being able to maintain the stability of wireless communication even if the communication conditions change during communication.
　（情報処理方法Ｓ１の流れ）
　次に、本例示的実施形態に係る情報処理方法Ｓ１の流れについて、図３を参照して説明する。図３は、情報処理方法Ｓ１の流れを示すフロー図である。 (Flow of information processing method S1)
Next, the flow of the information processing method S1 according to this exemplary embodiment will be described with reference to Fig. 3. Fig. 3 is a flow diagram showing the flow of the information processing method S1.
　図示するように、情報処理方法Ｓ１は、ステップＳ１１とステップＳ１２を含む。ステップＳ１１は、少なくとも１つのプロセッサ（例えば、特定部１１）が、複数の無線通信回線の各々において予測された経時的な帯域の変動範囲を示す予測帯域に応じて、移動体において取得されたデータを送信するための無線通信回線を選択する選択手法を特定するステップである。 As shown in the figure, information processing method S1 includes steps S11 and S12. Step S11 is a step in which at least one processor (e.g., identification unit 11) identifies a selection method for selecting a wireless communication line for transmitting data acquired in a mobile body according to a predicted bandwidth indicating a predicted range of bandwidth fluctuation over time in each of a plurality of wireless communication lines.
　ステップＳ１２は、少なくとも１つのプロセッサ（例えば、第１選択部１２）が、特定された選択手法を参照して、複数の無線通信回線の中からデータを送信する１以上の無線通信回線を送信中に選択するステップである。 Step S12 is a step in which at least one processor (e.g., the first selection unit 12) selects, during transmission, one or more wireless communication lines through which data is to be transmitted from among the multiple wireless communication lines, by referring to the identified selection method.
　以上の情報処理方法Ｓ１によれば、予測帯域に応じた無線通信回線を選択し、その回線を用いてデータを送信する。そのため、通信中に通信状況が変化した場合でも無線通信の安定性を保つことができる、という効果が得られる。 According to the information processing method S1 described above, a wireless communication line is selected according to the predicted band, and data is transmitted using that line. This has the effect of maintaining the stability of wireless communication even if the communication conditions change during communication.
　以上のように、本例示的実施形態に係る情報処理方法Ｓ１においては、少なくとも１つのプロセッサが、複数の無線通信回線の各々において予測された経時的な帯域の変動範囲を示す予測帯域に応じて、移動体において取得されたデータを送信するための無線通信回線を選択する選択手法を特定し、特定された選択手法を参照して、複数の無線通信回線の中からデータを送信する１以上の無線通信回線を送信中に選択する、という構成が採用されている。このため、本例示的実施形態に係る情報処理方法Ｓ１によれば、通信中に通信状況が変化した場合でも無線通信の安定性を保つことができる、という効果が得られる。 As described above, the information processing method S1 according to this exemplary embodiment is configured such that at least one processor identifies a selection method for selecting a wireless communication line for transmitting data acquired in a mobile body according to a predicted bandwidth indicating a predicted range of bandwidth fluctuation over time for each of a plurality of wireless communication lines, and selects, during transmission, one or more wireless communication lines for transmitting data from among the plurality of wireless communication lines by referring to the identified selection method. Therefore, the information processing method S1 according to this exemplary embodiment has the effect of maintaining the stability of wireless communication even if the communication conditions change during communication.
　〔例示的実施形態２〕
　本発明の第２の例示的実施形態について、図面を参照して詳細に説明する。なお、例示的実施形態１にて説明した構成要素と同じ機能を有する構成要素については、同じ符号を付し、その説明を適宜省略する。 Exemplary embodiment 2
A second exemplary embodiment of the present invention will be described in detail with reference to the drawings. Note that components having the same functions as those described in the first exemplary embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.
　（情報処理システム１Ａの構成）
　図４は、例示的実施形態２に係る情報処理システム１Ａの構成を示すブロック図である。図示するように、情報処理システム１Ａは、送信装置１０，受信装置２０，帯域調整装置３０及び制御装置４０を備える。一例として、情報処理システム１Ａは、移動体に搭載されたカメラからの映像を送受信し、異常がないか監視を行うための監視システムに用いることができる。なお、前述のように送信装置１０，受信装置２０，帯域調整装置３０及び制御装置４０は、異なる場所に配置されていてもよい。例えば、撮像装置と送信装置１０は移動体としての車に配置されており、受信装置２０は監視センター等に配置されていてもよい。また、帯域調整装置３０と制御装置４０は、そのいずれか、又は両方がクラウド上に、あるいは監視センターに配置されていてもよい。以下の例示的実施形態においては、データが撮像手段により撮像された映像データである場合を例にとって説明する。 (Configuration of Information Processing System 1A)
FIG. 4 is a block diagram showing a configuration of an information processing system 1A according to an exemplary embodiment 2. As shown in the figure, the information processing system 1A includes a transmitting device 10, a receiving device 20, a band adjustment device 30, and a control device 40. As an example, the information processing system 1A can be used as a monitoring system for transmitting and receiving images from a camera mounted on a moving body and monitoring whether there are any abnormalities. As described above, the transmitting device 10, the receiving device 20, the band adjustment device 30, and the control device 40 may be located in different locations. For example, the imaging device and the transmitting device 10 may be located in a car as a moving body, and the receiving device 20 may be located in a monitoring center or the like. In addition, either or both of the band adjustment device 30 and the control device 40 may be located on the cloud or in a monitoring center. In the following exemplary embodiment, a case in which the data is video data captured by an imaging means will be described as an example.
　送信装置１０は、特定部１１、第１選択部１２及びデータ送信部１３を備える。特定部１１と第１選択部１２の機能は、例示的実施形態１で説明した特定部１１と第１選択部１２の機能と同様である。データ送信部１３は、選択された無線通信回線１５を用いて映像データを送信する。送信装置１０は、一例として、移動体において撮像された映像データを取得し、無線通信により送信する装置である。移動体において撮像された映像データとは、例えば、車、電車、航空機、船舶等の移動体に搭載された、カメラ等の撮像装置（撮像手段）で撮像された映像データである。あるいは人が携帯可能な撮像装置により撮像した画像であってもよい。このような映像データは、経時的に撮影位置が変化する可能性がある映像データである。撮影位置は、連続的に変化してもよく、断続的に変化してもよい。映像データは、送信装置１０が撮像装置からリアルタイムで取得する。即ち、送信装置１０は、映像データを撮像した撮像装置と共に移動する。送信装置１０は、撮像装置と一体的に構成されていてもよい。 The transmitting device 10 includes an identifying unit 11, a first selecting unit 12, and a data transmitting unit 13. The functions of the identifying unit 11 and the first selecting unit 12 are the same as those of the identifying unit 11 and the first selecting unit 12 described in the exemplary embodiment 1. The data transmitting unit 13 transmits the video data using the selected wireless communication line 15. As an example, the transmitting device 10 is a device that acquires video data captured in a moving body and transmits it by wireless communication. The video data captured in a moving body is, for example, video data captured by an imaging device (imaging means) such as a camera mounted on a moving body such as a car, train, airplane, or ship. Alternatively, it may be an image captured by an imaging device that is portable by a person. Such video data is video data whose shooting position may change over time. The shooting position may change continuously or intermittently. The transmitting device 10 acquires the video data from the imaging device in real time. That is, the transmitting device 10 moves together with the imaging device that captured the video data. The transmitting device 10 may be configured integrally with the imaging device.
　受信装置２０は、第２選択部２１とデータ受信部２２を備える。受信装置２０は、送信装置１０から送信された映像データを受信する。データ受信部２２は、送信装置１０から送信された映像データを受信する。第２選択部２１は、送信装置１０の第１選択部１２によって映像データを送信する無線通信回線１５が複数選択された場合に、受信した複数の映像データの中から１つを選択する。つまり、第１選択部１２によって、映像データを送信する無線通信回線１５が複数選択された場合は、同じ映像データがその複数の無線通信回線ごとに送信される。そのため、第２選択部２１は、受信した複数の映像データのうち、映像の質が良い映像データを選択する。選択された映像データは図示しない表示装置に表示されてもよく、保存されてもよい。選択されなかった映像データは表示されず、保存されなくてもよい。 The receiving device 20 includes a second selection unit 21 and a data receiving unit 22. The receiving device 20 receives the video data transmitted from the transmitting device 10. The data receiving unit 22 receives the video data transmitted from the transmitting device 10. When the first selection unit 12 of the transmitting device 10 selects multiple wireless communication lines 15 for transmitting video data, the second selection unit 21 selects one of the multiple received video data. In other words, when the first selection unit 12 selects multiple wireless communication lines 15 for transmitting video data, the same video data is transmitted for each of the multiple wireless communication lines. Therefore, the second selection unit 21 selects the video data with the best video quality from the multiple received video data. The selected video data may be displayed on a display device (not shown) or may be saved. The unselected video data may not be displayed or saved.
　映像データは、一例として、図４に示すようにインターネットＮを介して送受信される。より具体的には、映像データは、送信装置１０から複数の無線通信回線１５のうち少なくとも１つを用いてインターネットＮの最寄りの接続点まで送信される。また、映像データは、受信装置２０の最寄りのインターネットＮの接続点から有線通信回路２５、又は無線通信回線２５を介して受信装置２０により受信される。受信装置２０は、請求の範囲に記載した受信手段の一形態である。第２選択部２１は、請求の範囲に記載した第２選択手段の一形態である。 As an example, the video data is transmitted and received via the Internet N as shown in FIG. 4. More specifically, the video data is transmitted from the transmitting device 10 to the nearest connection point of the Internet N using at least one of a plurality of wireless communication lines 15. The video data is received by the receiving device 20 from the nearest connection point of the Internet N to the receiving device 20 via a wired communication circuit 25 or a wireless communication line 25. The receiving device 20 is one form of the receiving means described in the claims. The second selection unit 21 is one form of the second selection means described in the claims.
　インターネットＮから受信装置２０までの回線２５は、通常は１つの回線を使用する。その理由は、例えば監視センターに設置される受信装置２０は移動せず、決まった場所に存在するため、安定している有線通信回線を用いてもよく、あるいはその場所において最も品質の良い無線通信回線を用いればよいからである。 Normally, one line is used as the line 25 from the Internet N to the receiving device 20. The reason for this is that, for example, the receiving device 20 installed in a monitoring center does not move and is located in a fixed place, so a stable wired communication line may be used, or the wireless communication line with the best quality at that location may be used.
　帯域調整装置３０は、予測帯域を参照して、複数の無線通信回線１５の各々において映像データを送信する帯域を調整する。帯域調整装置３０は、帯域変動予測部３１と、送信帯域調整部３２を備える。帯域変動予測部３１は、無線通信回線１５の各々において、近い将来の帯域がどの程度になるかを示す予測帯域を予測する。帯域変動予測部３１は、例えば、経時的な帯域の変動情報を取得し、その変動の傾向から近い将来の帯域の変動の傾向を予測してもよい。あるいは、帯域変動予測部３１は、帯域の過去の変動から近い将来の変動を予測する帯域予測モデルを用いて帯域変動を予測してもよい。予測された経時的な帯域の変動範囲を予測帯域という。近い将来とは数分先まで、数十分先まで、あるいは数時間先までであってもよい。予測は帯域変動予測部３１によって適宜実行され、予測帯域が更新される。 The bandwidth adjustment device 30 adjusts the bandwidth for transmitting video data in each of the multiple wireless communication lines 15 by referring to the predicted bandwidth. The bandwidth adjustment device 30 includes a bandwidth fluctuation prediction unit 31 and a transmission bandwidth adjustment unit 32. The bandwidth fluctuation prediction unit 31 predicts a predicted bandwidth indicating the extent of the bandwidth in the near future in each of the wireless communication lines 15. The bandwidth fluctuation prediction unit 31 may, for example, acquire information on fluctuations in the bandwidth over time and predict the trend of the near future fluctuations in the bandwidth from the trend of the fluctuations. Alternatively, the bandwidth fluctuation prediction unit 31 may predict the bandwidth fluctuation using a bandwidth prediction model that predicts the near future fluctuations from past fluctuations in the bandwidth. The predicted range of fluctuations in the bandwidth over time is called the predicted bandwidth. The near future may be up to a few minutes ahead, up to a few tens of minutes ahead, or up to a few hours ahead. The prediction is performed as appropriate by the bandwidth fluctuation prediction unit 31, and the predicted bandwidth is updated.
　送信帯域調整部３２は、複数の無線通信回線１５の各々において予測された予測帯域を参照して、映像データを送信する帯域である送信帯域を調整する。つまり、帯域調整装置３０は、ある無線通信回線１５の帯域が減少すると予測された場合は、その無線通信回線１５を用いて送信する場合の映像データの送信帯域を小さく設定する。逆に、ある無線通信回線１５の帯域が増加すると予測された場合は、その無線通信回線１５を用いて送信する場合の映像データの送信帯域を大きく設定する。送信帯域調整部３２は、複数の無線通信回線１５の各々において映像データの送信帯域を調整してもよい。帯域調整装置３０は、請求の範囲に記載した帯域調整手段の一形態である。 The transmission bandwidth adjustment unit 32 adjusts the transmission bandwidth, which is the bandwidth for transmitting video data, by referring to the predicted bandwidth predicted for each of the multiple wireless communication lines 15. In other words, if the bandwidth of a certain wireless communication line 15 is predicted to decrease, the bandwidth adjustment device 30 sets the transmission bandwidth of the video data to be transmitted using that wireless communication line 15 to be small. Conversely, if the bandwidth of a certain wireless communication line 15 is predicted to increase, the transmission bandwidth of the video data to be transmitted using that wireless communication line 15 is set to be large. The transmission bandwidth adjustment unit 32 may adjust the transmission bandwidth of the video data for each of the multiple wireless communication lines 15. The bandwidth adjustment device 30 is one form of the bandwidth adjustment means described in the claims.
　制御装置４０は、情報処理システム１Ａの全体を統括制御する。制御装置４０は、少なくとも１つのプロセッサ４１と、少なくとも１つのメモリ４２を備える。プロセッサ４１は、例えば、少なくとも１つのＭＰＵ（Micro Processing Unit）、ＣＰＵ（Central Processing Unit）等の汎用プロセッサを用いて構成することができる。メモリ４２は、ＲＯＭ（Read Only Memory）、ＲＡＭ（Random Access Memory）等の複数種類のメモリを備えていてもよい。一例として、プロセッサ４１は、メモリ４２のＲＯＭに記録された各種の制御プログラムをＲＡＭに展開して実行することにより、送信装置１０，受信装置２０，帯域調整装置３０としての機能を実現する。なお、制御装置４０は、その制御対象に応じて複数設けられていてもよい。また、複数の制御装置は離間して配置されていてもよい。また、プロセッサ４１は、ＡＳＩＣ（Application Specific Integrated Circuit）、ＦＰＧＡ（Field Programmable Gate Array）又はＰＬＤ（Programmable Logic Device）等で構成されるプロセッサを含んでいてもよい。 The control device 40 controls the entire information processing system 1A. The control device 40 has at least one processor 41 and at least one memory 42. The processor 41 can be configured using, for example, at least one general-purpose processor such as an MPU (Micro Processing Unit) or a CPU (Central Processing Unit). The memory 42 may have multiple types of memory such as a ROM (Read Only Memory) and a RAM (Random Access Memory). As an example, the processor 41 realizes the functions of the transmitting device 10, the receiving device 20, and the bandwidth adjustment device 30 by expanding various control programs recorded in the ROM of the memory 42 into the RAM and executing them. Note that multiple control devices 40 may be provided depending on the objects to be controlled. Furthermore, the multiple control devices may be arranged at a distance from each other. The processor 41 may also include a processor configured as an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a PLD (Programmable Logic Device), etc.
　次に、送信装置１０の第１選択部１２が無線通信回線１５を選択する選択手法について説明する。一例として、特定部１１が特定する選択手法は、予測帯域を参照して、複数の無線通信回線１５の中から優先的に映像データを送信する優先回線を決定し、送信帯域を割り当て可能な回線を予備回線とする手法であってもよい。 Next, a selection method by which the first selection unit 12 of the transmitting device 10 selects the wireless communication line 15 will be described. As an example, the selection method identified by the identification unit 11 may be a method in which a predicted bandwidth is referenced to determine a priority line from among the multiple wireless communication lines 15 for preferentially transmitting video data, and a line to which a transmission bandwidth can be allocated is designated as a backup line.
　また、特定部１１が特定する選択手法は、送信装置１０が位置する通信エリアを参照して、割当帯域マップを決定する手法であってもよい。例えば、図５の５１０に示すように、送信装置１０が車に搭載されているとする。その場合、第１選択部１２は、Ｗｉ－Ｆｉ（登録商標）１が利用可能な店舗近傍エリア５１１、Ｗｉ－Ｆｉ（登録商標）２を利用可能な自宅近傍エリア５１２のように、Ｗｉ－Ｆｉ（登録商標）接続ポイントに近いエリアでは、Ｗｉ－Ｆｉ（登録商標）回線を優先回線と決定してもよい。Ｗｉ－Ｆｉ（登録商標）回線を使用する場合は、基本的に費用が発生しないためである。あるいは、コスト以外にも、使用する回線を通信速度、安全性等を考慮して予め決めていてもよい。また、第１選択部１２は、エリア５１３のように、Ｗｉ－Ｆｉ（登録商標）の帯域が小さい場合、又は接続ポイントに接続できない場合などに、ＬＴＥ１回線を代替回線としてもよい。また、第１選択部１２は、衛星通信回線を、Ｗｉ－Ｆｉ（登録商標）回線とＬＴＥ回線の両方が使えない場合の予備回線としてもよい。 The selection method specified by the identification unit 11 may be a method of determining an allocation band map by referring to the communication area in which the transmitting device 10 is located. For example, as shown in 510 in FIG. 5, the transmitting device 10 is mounted on a car. In that case, the first selection unit 12 may determine the Wi-Fi (registered trademark) line as the priority line in areas close to the Wi-Fi (registered trademark) connection point, such as the store vicinity area 511 where Wi-Fi (registered trademark) 1 is available and the home vicinity area 512 where Wi-Fi (registered trademark) 2 is available. This is because there is basically no cost when using the Wi-Fi (registered trademark) line. Alternatively, the line to be used may be determined in advance taking into consideration communication speed, safety, and the like in addition to cost. The first selection unit 12 may also set the LTE1 line as the alternative line when the band of Wi-Fi (registered trademark) is small, such as in area 513, or when it is not possible to connect to the connection point. The first selection unit 12 may also use the satellite communication line as a backup line when both the Wi-Fi (registered trademark) line and the LTE line are unavailable.
　また、例えば、図５の５２０に示すように、送信装置１０が船舶に搭載されているとする。その場合、選択手法は、国内の都市圏５２２，５２３，５２４又は外国の都市圏５２６ではＷｉ－Ｆｉ（登録商標）３回線又はＷｉ－Ｆｉ（登録商標）４回線を、近海エリア５２１，５２５ではＬＴＥ２回線又はＬＴＥ３回線を使用し、それ以外の海洋エリア５２８では衛星通信回線を選択する手法であってもよい。また、選択手法は、優先回線を決定する手法と、通信エリアを参照して無線通信回線を決定する手法を組み合わせた手法でもよい。 Also, for example, assume that the transmitting device 10 is mounted on a ship, as shown in 520 in FIG. 5. In this case, the selection method may be a method of using Wi-Fi (registered trademark) 3 lines or Wi-Fi (registered trademark) 4 lines in domestic metropolitan areas 522, 523, 524 or foreign metropolitan area 526, using LTE 2 lines or LTE 3 lines in near- shore areas 521, 525, and selecting a satellite communication line in other marine areas 528. The selection method may also be a combination of a method of determining a priority line and a method of determining a wireless communication line by referring to the communication area.
　また、特定部１１が特定する選択手法は、複数の無線通信回線ごとに割り当てられた送信帯域を示す、予め作成された複数の割当帯域マップの中から１つを選択する手法であってもよい。割当帯域マップは、複数の無線通信回線の送信可能な帯域（送信帯域）を相互に参照して、各回線の使用帯域を決める手法をマップで表したものである。この方法について、図面を参照して具体的に説明する。図６から図９は、第１選択部１２が選択する割当帯域マップの例を示す模式図である。 The selection method identified by the identification unit 11 may be a method of selecting one from a plurality of pre-created allocation band maps that indicate the transmission bands allocated to each of a plurality of wireless communication lines. The allocation band map is a map that represents a method of determining the bandwidth to be used for each line by mutually referring to the transmittable bands (transmission bands) of a plurality of wireless communication lines. This method will be specifically described with reference to the drawings. Figures 6 to 9 are schematic diagrams showing examples of allocation band maps selected by the first selection unit 12.
　図６を用いて、割当帯域マップを用いて回線と帯域を選択する基本的な考え方を説明する。図６の横軸はＷｉ－Ｆｉ（登録商標）回線の帯域（ｂｐｓ）値、縦軸はＬＴＥ回線の帯域（ｂｐｓ）値を示す。また、実線で囲んだ領域６０１は、Ｗｉ－Ｆｉ（登録商標）回線の送信帯域であり、最小値がＹ、最大値が送信maxで示す値であるとする。送信maxは、回線のmax値よりも小さい。割当帯域マップの送信帯域とは、無線通信回線ごとに設定された、良好な映像データを送信するのに十分な帯域の範囲である。１点鎖線で囲んだ領域６０２は、ＬＴＥ回線の送信帯域で、最小値がＺ、最大値が送信maxで示す値であるとする。送信maxは、回線のmax値よりも小さい。２点鎖線で囲んだ領域６０３は、衛星回線の送信帯域であり、Ｗｉ－Ｆｉ（登録商標）回線とＬＴＥ回線のいずれもがカバーできない領域をカバーしている。なお、以降の図７－９においても、横軸と縦軸は同様であり、送信帯域の表示態様も同様である。 The basic idea of selecting a line and a band using the allocation band map will be explained using Figure 6. The horizontal axis of Figure 6 indicates the band (bps) value of the Wi-Fi (registered trademark) line, and the vertical axis indicates the band (bps) value of the LTE line. The area 601 surrounded by a solid line is the transmission band of the Wi-Fi (registered trademark) line, with the minimum value being Y and the maximum value being the value indicated by transmission max. Transmission max is smaller than the max value of the line. The transmission band of the allocation band map is a range of bands set for each wireless communication line that is sufficient for transmitting good quality video data. The area 602 surrounded by a dashed line is the transmission band of the LTE line, with the minimum value being Z and the maximum value being the value indicated by transmission max. Transmission max is smaller than the max value of the line. The area 603 surrounded by a dashed line is the transmission band of the satellite line, and covers an area that cannot be covered by either the Wi-Fi (registered trademark) line or the LTE line. In the following Figures 7-9, the horizontal and vertical axes are the same, and the transmission bandwidth is displayed in the same way.
　ある回線の予測帯域がその送信帯域内にない場合は、その回線は無条件に使用しない。例えば、ある時点での予測帯域が、Ｗｉ－Ｆｉ（登録商標）回線がＶ、ＬＴＥ回線がＺ’であったとする。Ｖは、Ｗｉ－Ｆｉ（登録商標）回線の送信帯域６０１の外にある。その場合、第１選択部１２は無条件でＬＴＥ回線を選択する。送信部１０は、予測帯域に応じて調整された帯域で映像データを送信する。複数の回線が使用可能な場合（送信帯域がオーバーラップする範囲）は、送信部１０は、複数の回線を使用して送信してもよい。その場合、受信側で品質が良い映像データを選択する。品質が良い映像データとは、例えば平均ビットレートが最も大きい映像データである。 If the predicted bandwidth of a line is not within the transmission bandwidth, that line will not be used unconditionally. For example, assume that the predicted bandwidth at a certain point in time is V for the Wi-Fi (registered trademark) line and Z' for the LTE line. V is outside the transmission bandwidth 601 of the Wi-Fi (registered trademark) line. In that case, the first selection unit 12 unconditionally selects the LTE line. The transmission unit 10 transmits video data in a bandwidth adjusted according to the predicted bandwidth. If multiple lines are available (a range in which the transmission bandwidths overlap), the transmission unit 10 may transmit using multiple lines. In that case, the receiving side selects video data with good quality. Video data with good quality is, for example, video data with the highest average bit rate.
　それ以外の考え方は、例えば次のとおりである。まず、Ｗｉ－Ｆｉ（登録商標）回線を優先する。また、Ｗｉ－Ｆｉ（登録商標）の予測帯域がＸよりも大きければ、ＬＴＥ回線での送信をオフにする（Ｗｉ－Ｆｉ（登録商標）のみ用いる）。Ｘの値は、ある程度任意でもよい。例えば、Ｘは３Ｍｂｐｓとすることができる。また、Ｗｉ－Ｆｉ（登録商標）の予測帯域がＸ以下であれば、ＬＴＥ回線での送信をオンにする。Ｗｉ－Ｆｉ（登録商標）の予測帯域がＹより小さい場合は、Ｗｉ－Ｆｉ（登録商標）回線での送信をオフにする。Ｙは、例えば数百ｋｂｐｓとすることができる。 Other ways of thinking are, for example, as follows. First, give priority to the Wi-Fi (registered trademark) line. Also, if the predicted bandwidth of Wi-Fi (registered trademark) is greater than X, transmission on the LTE line is turned off (only Wi-Fi (registered trademark) is used). The value of X can be somewhat arbitrary. For example, X can be 3 Mbps. Also, if the predicted bandwidth of Wi-Fi (registered trademark) is equal to or less than X, transmission on the LTE line is turned on. If the predicted bandwidth of Wi-Fi (registered trademark) is smaller than Y, transmission on the Wi-Fi (registered trademark) line is turned off. Y can be, for example, several hundred kbps.
　図７は、比較的シンプルな選択方法を用いる場合の割当帯域マップの一例である。図７の例では、Ｗｉ－Ｆｉ（登録商標）回線の送信帯域とＬＴＥ回線の送信帯域だけが指定されている。それぞれ、送信minから送信maxまでで示された範囲である。この場合は、各回線の予測帯域がそれぞれの送信帯域に含まれる場合は、それぞれの回線で独立して調整された帯域で映像データを送信する。その場合、受信側で品質が良い映像データを選択する。図７のような割当帯域マップを用いる場合は、可能な限り複数の回線でそれぞれ送信するため、送信時点で最大限の品質の映像データを送信することができる。 Figure 7 is an example of an allocation bandwidth map when a relatively simple selection method is used. In the example of Figure 7, only the transmission bandwidth of the Wi-Fi (registered trademark) line and the transmission bandwidth of the LTE line are specified. Each is in the range indicated by transmission min to transmission max. In this case, if the predicted bandwidth of each line is included in the respective transmission bandwidth, video data is transmitted at a bandwidth adjusted independently for each line. In that case, the receiving side selects video data with good quality. When an allocation bandwidth map like that of Figure 7 is used, transmission is performed using as many lines as possible, so video data of the highest quality can be transmitted at the time of transmission.
　図８は、ＬＴＥ回線が使える範囲では、Ｗｉ－Ｆｉ（登録商標）回線の送信帯域の最大値をＬＴＥ回線の送信帯域の最大値に合わせる手法の割当帯域マップの一例である。図８に示す例では、ＬＴＥ回線が使える範囲では、Ｗｉ－Ｆｉ（登録商標）回線の送信帯域の最大値をＬＴＥmax（ＬＴＥ回線の送信帯域の最大値）に制限している。ＬＴＥ回線とＷｉ－Ｆｉ（登録商標）回線の両方が使える範囲では、それぞれ独立して調整された帯域で映像データを送信し、受信側で品質が良い映像データを選択する。このような選択手法により、ＬＴＥ回線による映像とＷｉ－Ｆｉ（登録商標）回線による映像を切り替える際に、映像の品質の差が出にくくなる。つまり、回線を切り替えた際の映像の品質の変化を小さくし、回線切り替え時の違和感を低減することができる。 FIG. 8 is an example of an allocation bandwidth map for a method of matching the maximum transmission bandwidth of a Wi-Fi (registered trademark) line to the maximum transmission bandwidth of an LTE line when an LTE line is available. In the example shown in FIG. 8, when an LTE line is available, the maximum transmission bandwidth of a Wi-Fi (registered trademark) line is limited to LTEmax (the maximum transmission bandwidth of an LTE line). When both an LTE line and a Wi-Fi (registered trademark) line are available, video data is transmitted at independently adjusted bandwidths, and the receiving side selects the video data with the best quality. This selection method reduces the difference in video quality when switching between video via an LTE line and video via a Wi-Fi (registered trademark). In other words, it is possible to reduce the change in video quality when switching lines, and reduce the sense of discomfort when switching lines.
　図９は、Ｗｉ－Ｆｉ（登録商標）回線は独立して帯域を調整し、Ｗｉ－Ｆｉ（登録商標）回線が使用可能な帯域では、ＬＴＥ回線は送信帯域を割り当てない（送信しない）ようにする割当帯域マップの一例である。具体的には、ＬＴＥ回線の送信帯域の下限値である送信minと、Ｗｉ－Ｆｉ（登録商標）回線の送信帯域の上限値である送信maxとの交点から傾きがマイナス１の線を引き（横軸と縦軸の目盛間隔は同じ）、その線より右側のＬＴＥ回線の送信帯域は割り当てない。ＬＴＥ回線とＷｉ－Ｆｉ（登録商標）回線の両方が使える範囲では、それぞれ独立して調整された帯域で映像データを送信し、受信側で品質が良い映像データを選択する。このような選択手法により、Ｗｉ－Ｆｉ（登録商標）回線を優先しつつ、映像の品質もできるだけ保つように送信を最適化することができる。 Figure 9 shows an example of an allocation bandwidth map in which the bandwidth of the Wi-Fi (registered trademark) line is adjusted independently, and the LTE line is not assigned (does not transmit) a transmission bandwidth in a bandwidth that the Wi-Fi (registered trademark) line can use. Specifically, a line with a slope of minus 1 is drawn from the intersection of the transmission min, which is the lower limit of the transmission bandwidth of the LTE line, and the transmission max, which is the upper limit of the transmission bandwidth of the Wi-Fi (registered trademark) line (the scale intervals on the horizontal and vertical axes are the same), and the transmission bandwidth of the LTE line to the right of the line is not assigned. In the range where both the LTE line and the Wi-Fi (registered trademark) line can be used, video data is transmitted in independently adjusted bandwidths, and the receiving side selects the video data with the best quality. This selection method makes it possible to optimize transmission so as to maintain as much video quality as possible while giving priority to the Wi-Fi (registered trademark) line.
　図１０は、図６から図９に例示した割当帯域マップを、複数の回線の予測帯域の変化に応じて特定する模式図である。例えば、特定部１１は、複数の回線の予測帯域の結果を相互に参照して、割当帯域マップを特定してもよい。例えば、図の左下のマップでは、回線１の送信帯域１００１と回線２の送信帯域１００２が一部重なっている。一方、右上のマップでは、回線１の送信帯域１００３と回線２の送信帯域１００４とは重なっていない。このように、ユーザのポリシ（例えば、コスト、通信速度、安全性など、どの条件を優先するか等の方針）に応じて、使用する割当帯域マップを特定することができる。あるいは、特定部１１は、送信装置が位置する通信エリアにより、割当帯域マップを特定してもよい。 10 is a schematic diagram of the allocation bandwidth map illustrated in FIG. 6 to FIG. 9 being identified according to changes in the predicted bandwidth of multiple lines. For example, the identification unit 11 may identify the allocation bandwidth map by mutually referring to the results of the predicted bandwidth of multiple lines. For example, in the map in the lower left of the figure, the transmission bandwidth 1001 of line 1 and the transmission bandwidth 1002 of line 2 partially overlap. On the other hand, in the map in the upper right, the transmission bandwidth 1003 of line 1 and the transmission bandwidth 1004 of line 2 do not overlap. In this way, the allocation bandwidth map to be used can be identified according to the user's policy (for example, a policy on which conditions are to be prioritized, such as cost, communication speed, or safety). Alternatively, the identification unit 11 may identify the allocation bandwidth map according to the communication area in which the transmitting device is located.
　以上のように、本例示的実施形態に係る情報処理システム１Ａにおいては、第１選択部１２は、予測帯域を参照して、複数の無線通信回線の中から優先的に前記データを送信する優先回線を決定し、送信帯域を割り当て可能な回線を予備回線とする手法で、映像を送信する無線通信回線を特定する、という構成が採用されている。このため、本例示的実施形態に係る情報処理システム１Ａによれば、例示的実施形態１に係る情報処理システム１の奏する効果に加えて、Ｗｉ－Ｆｉ（登録商標）回線を優先的に選択することにより、通信コストを低減することができるという効果が得られる。 As described above, in the information processing system 1A according to this exemplary embodiment, the first selection unit 12 refers to the predicted bandwidth, determines a priority line from among multiple wireless communication lines to transmit the data preferentially, and identifies the wireless communication line to transmit the video by using a method in which a line to which a transmission bandwidth can be allocated is designated as a backup line. Therefore, according to the information processing system 1A according to this exemplary embodiment, in addition to the effects of the information processing system 1 according to the exemplary embodiment 1, the effect of reducing communication costs can be obtained by preferentially selecting a Wi-Fi (registered trademark) line.
　また、本例示的実施形態に係る情報処理システム１Ａにおいては、第１選択部１２は、複数の無線通信回線ごとに割り当てられた送信帯域を示す、予め作成された複数の割当帯域マップの中から１つを選択する手法で、映像を送信する無線通信回線を特定する、という構成が採用されている。このため、本例示的実施形態に係る情報処理システム１Ａによれば、例示的実施形態１に係る情報処理システム１の奏する効果に加えて、予め作成された複数の割当帯域マップの中から１つを選択することにより、効率的に回線を選択することができるという効果が得られる。 Furthermore, in the information processing system 1A according to this exemplary embodiment, the first selection unit 12 is configured to identify the wireless communication line for transmitting the video by selecting one from a plurality of pre-created allocation bandwidth maps that indicate the transmission bandwidth allocated to each of a plurality of wireless communication lines. Therefore, according to the information processing system 1A according to this exemplary embodiment, in addition to the effect of the information processing system 1 according to the exemplary embodiment 1, the effect of being able to efficiently select a line by selecting one from a plurality of pre-created allocation bandwidth maps is obtained.

Alternatively, the first selection unit 12 employs a selection method in which it identifies the wireless communication line to transmit video by selecting one from multiple pre-created allocation bandwidth maps that indicate the transmission bandwidth allocated to each of the multiple wireless communication lines. Therefore, according to the information processing device 2A according to this exemplary embodiment, it is possible to obtain effects similar to those obtained by the information processing system 1A.
　（情報処理方法Ｓ２の流れ）
　次に、本例示的実施形態に係る情報処理方法Ｓ２の流れについて、図１２を参照して説明する。図１２は、情報処理方法Ｓ２の流れを示すフロー図である。 (Flow of information processing method S2)
Next, the flow of the information processing method S2 according to this exemplary embodiment will be described with reference to Fig. 12. Fig. 12 is a flow diagram showing the flow of the information processing method S2.

　ステップＳ２６は、少なくとも１つのプロセッサ（例えば、制御部４０）が、送信が終了したか否かを判定するステップである。ステップＳ２６において、送信が終了したと判定された場合（ステップＳ２６：ＹＥＳ）は、情報処理を終了する。ステップＳ２６において、送信が終了していないと判定された場合（ステップＳ２６：ＮＯ）は、ステップＳ２１に戻る。 Step S26 is a step in which at least one processor (e.g., control unit 40) determines whether or not the transmission has ended. If it is determined in step S26 that the transmission has ended (step S26: YES), the information processing ends. If it is determined in step S26 that the transmission has not ended (step S26: NO), the process returns to step S21.
　なお、図１２には示していないが、情報処理方法Ｓ２は、送信された映像データを受信すること、受信した映像データが複数ある場合は、受信した複数の映像データの中から１つを選択することをさらに含んでもよい。 Note that, although not shown in FIG. 12, information processing method S2 may further include receiving the transmitted video data, and, if there are multiple pieces of video data received, selecting one of the multiple pieces of video data received.
