- This disclosure relates to a communication control system, a communication control device, and a communication control method.
- optical fibers are installed all over the country and are used as communication routes. In order to ensure stable communication without interruptions, it is important to select the optimal communication route to use for a given communication.
- Patent Document 1 describes a technique for selecting a communication path to be used for communication in which data is transmitted from a transmitting terminal to a receiving terminal via a plurality of repeaters. Specifically, according to the technology described in Patent Document 1, an abnormality in each repeater is predicted based on the transmission quality at each repeater, and a communication path is selected from multiple communication paths after excluding a communication path that includes a repeater for which an abnormality is predicted.
- the technology described in Patent Document 1 can predict that a communication path will be interrupted due to an abnormality caused by deterioration of transmission quality at each repeater.
- the technology described in Patent Document 1 cannot predict that a communication path will be interrupted due to an abnormality in the external environment around the optical fiber (e.g., landslides, earthquakes, etc.). Therefore, even if a communication path is selected using the technology described in Patent Document 1, there is a problem in that a communication interruption due to an abnormality in the external environment may occur on the selected communication path, making it impossible to continue communication.
- the objective of this disclosure is to provide a communication control system, a communication control device, and a communication control method that are capable of selecting a communication path while taking into account abnormalities in the external environment around the optical fiber.
- a communication control system includes: A plurality of optical fibers; a detection unit that detects an abnormality in an external environment around the plurality of optical fibers based on an optical signal received from each of the plurality of optical fibers; a prediction unit that predicts whether or not the abnormality has an effect on a communication path based on the detected abnormality; and a selection unit that selects, based on the presence or absence of the predicted effect of the abnormality on the communication path, a communication path that is not affected by the abnormality as the communication path to be used for a specified communication.
- a communication control device includes: a detection unit that detects an abnormality in an external environment around the plurality of optical fibers based on an optical signal received from each of the plurality of optical fibers; a prediction unit that predicts whether or not the abnormality has an effect on a communication path based on the detected abnormality; and a selection unit that selects, based on the presence or absence of the predicted effect of the abnormality on the communication path, a communication path that is not affected by the abnormality as the communication path to be used for a specified communication.
- a communication control method includes: A communication control method by a communication control device, a detection step of detecting an abnormality in an external environment around the plurality of optical fibers based on an optical signal received from each of the plurality of optical fibers; a prediction step of predicting whether or not the abnormality has an effect on a communication path based on the detected abnormality; and a selection step of selecting, based on the presence or absence of the predicted effect of the abnormality on the communication path, a communication path that is not affected by the abnormality as the communication path to be used for a predetermined communication.
- the above-mentioned aspects provide an advantage in that it is possible to provide a communication control system, a communication control device, and a communication control method that can select a communication path while taking into account abnormalities in the external environment around the optical fiber.

- the communication control system according to the first embodiment includes a plurality of optical fibers 10-1 to 10-n (n is an integer of 2 or more) and a communication control device 20.
- n is an integer of 2 or more
- the optical fiber 10 when it is not necessary to specify which of the optical fibers 10-1 to 10-n is being referred to, it will be simply referred to as the "optical fiber 10.”
- the optical fiber 10 is laid in a specified area. There are no particular limitations on the manner in which the optical fiber 10 is laid.
- the optical fiber 10 may be laid overhead on a pole such as a utility pole, or may be buried underground.
- the communication control device 20 is a device for selecting a communication path to be used for a specific communication, and is realized by, for example, a sensing device such as a Distributed Fiber Optic Sensing (DFOS) device.
- the specific communication is, for example, communication that transmits data from a transmitting device to a receiving device.
- DFOS Distributed Fiber Optic Sensing
- the communication path that can be selected for use in a given communication is any one of the multiple optical fibers 10, and a wireless line via a communication satellite, base station, etc.
- the communication control device 20 includes a detection unit 21, a prediction unit 22, and a selection unit 23.
- a plurality of optical fibers 10 are connected to the detection unit 21 .
- the detection unit 21 transmits pulsed light to each of the plurality of optical fibers 10.
- the detection unit 21 receives backscattered light generated as the pulsed light is transmitted through each of the plurality of optical fibers 10 as an optical signal from each of the plurality of optical fibers 10.
- the vibrations caused by the abnormality are transmitted to the optical fiber 10, and the characteristics (e.g., wavelength) of the optical signal transmitted through the optical fiber 10 change.
- the detection unit 21 can detect vibrations transmitted to the optical fiber 10 based on the optical signal received from the optical fiber 10, and can also detect abnormalities that are the cause of the vibrations.
- the detection unit 21 can identify the location where the optical signal was generated, i.e., the location where the abnormality detected based on the optical signal occurred (the distance of the optical fiber 10 from the communication control device 20).
- the detection unit 21 also holds in advance a correspondence table that indicates, for each of the multiple optical fibers 10, the distance from the communication control device 20 on that optical fiber 10 and the latitude/longitude at that distance.
- An example of the correspondence table is shown in FIG. 2. Therefore, by using a correspondence table such as that shown in FIG. 2, the detection unit 21 can identify the latitude/longitude of the location where an abnormality has occurred. For example, in the example of FIG. 2, if an abnormality has occurred at a position on the optical fiber 10-1 that is a distance 1a from the communication control device 20, the detection unit 21 identifies the location where the abnormality has occurred as being at latitude/longitude X1a/Y1a.
- the correspondence table is not limited to being held by the detection unit 21.
- any component inside or outside the communication control device 20 may hold the correspondence table, and the detection unit 21 may read and use the correspondence table.
- the vibrations transmitted to the optical fiber 10 have unique vibration patterns that vary in strength, vibration position, and frequency fluctuation depending on the type of abnormality.
- the detection unit 21 may therefore estimate the type of abnormality in the external environment around the optical fiber 10 based on the vibration pattern of the vibration detected based on the optical signal.
- the types of abnormality in the external environment include, for example, landslides, earthquakes, traffic accidents, floods, tsunamis, and fires.
- the detection unit 21 may also use pattern matching or a learning model when estimating the type of abnormality in the external environment around the optical fiber 10.
- the learning model may also be a model that includes a CNN (Convolutional Neural Network).
- the detection unit 21 stores in advance, for each type of abnormality in the external environment, the vibration pattern that occurs when that type of abnormality occurs as a matching pattern. The detection unit 21 then compares the vibration pattern of the vibration detected based on the optical signal with the matching pattern. If there is a matching pattern among the matching patterns whose compatibility with the vibration pattern is equal to or exceeds a threshold value, the detection unit 21 determines that the type of abnormality in the external environment corresponds to that matching pattern.
- the detection unit 21 uses a learning model
- the detection unit 21 inputs multiple pairs of teacher data indicating the type of abnormality in the external environment and the vibration pattern when that type of abnormality occurs, and constructs and stores the learning model in advance.
- the detection unit 21 then inputs the vibration pattern of the vibration detected based on the optical signal to the learning model.
- the detection unit 21 obtains the type of abnormality in the external environment as the output result of the learning model.
- the matching patterns and learning models are not limited to being stored by the detection unit 21.
- any component inside or outside the communication control device 20 may store the matching patterns and learning models, and the detection unit 21 may read and use the matching patterns and learning models.
- the detection unit 21 may further estimate the scale of the abnormality in the external environment based on the estimated type of abnormality in the external environment.
- the prediction unit 22 predicts whether or not the communication path will be affected by the abnormality in the external environment, based on the abnormality in the external environment detected by the detection unit 21. For example, the prediction unit 22 may predict that a communication path that includes a location where a communication interruption may occur due to the abnormality in the external environment will be affected by the abnormality in the external environment.
- the prediction unit 22 may identify an area in which communication interruption may occur based on the estimated type and scale of the abnormality in the external environment, and when all or part of the communication path is included in the identified area, predict that the communication path will be affected by the abnormality in the external environment.
- the selection unit 23 selects a communication path that is not affected by an abnormality in the external environment as the communication path to be used for a specified communication, based on whether or not the communication path predicted by the prediction unit 22 is affected by an abnormality in the external environment.
- a specific example of a communication path selected by the selection unit 23 will be described.
- a communication path to be used for communication to transmit data from the transmitting device 30 to the receiving device 40 is selected. It is also assumed that two optical fibers 10-1 and 10-2 are laid between the transmitting device 30 and the receiving device 40.
- the prediction unit 22 predicts that only the optical fiber 10-1 will be affected by the abnormality in the external environment because the scale of the abnormality in the external environment is small. Therefore, the selector 23 selects the optical fiber 10-2, which is not affected by abnormalities in the external environment, as the communication path to be used for communication.
- the prediction unit 22 predicts that both of the two optical fibers 10-1 and 10-2 will be affected by the abnormality in the external environment because the abnormality in the external environment is large in scale. Therefore, the selection unit 23 selects, as the communication path to be used for communication, a wireless link via the communication satellite 50, which is not affected by abnormalities in the external environment.
- the selection unit 23 is not limited to selecting a wireless link via the communication satellite 50, and may select a wireless link via a base station (not shown) that is not affected by abnormalities in the external environment.
- the detection unit 21 transmits pulsed light to each of the multiple optical fibers 10 and receives optical signals from each of the multiple optical fibers 10. Then, the detection unit 21 detects an abnormality in the external environment around the multiple optical fibers 10 based on the optical signals received from each of the multiple optical fibers 10 (step S11).
- the prediction unit 22 predicts whether or not the abnormality in the external environment will have an effect on the communication path, based on the abnormality in the external environment detected by the detection unit 21 (step S12). Then, the selection unit 23 selects a communication path that is not affected by the abnormality in the external environment as the communication path to be used for the specified communication, based on whether or not the communication path predicted by the prediction unit 22 is affected by the abnormality in the external environment (step S13).
- the detection unit 21 detects an abnormality in the external environment surrounding the multiple optical fibers 10 based on the optical signals received from each of the multiple optical fibers 10.
- the prediction unit 22 predicts whether or not the communication path will be affected by the abnormality in the external environment based on the abnormality in the external environment detected by the detection unit 21.
- the selection unit 23 selects a communication path that is not affected by the abnormality in the external environment as the communication path to be used for the specified communication based on the presence or absence of the influence of the abnormality in the external environment on the communication path predicted by the prediction unit 22.
- the communication path to be used for the specified communication can be selected taking into consideration abnormalities in the external environment around the optical fiber 10. This allows the communication path to be selected while avoiding locations or areas where communication interruptions may occur due to abnormalities in the external environment. As a result, the specified communication can be continued without communication interruptions due to abnormalities in the external environment, and the specified communication can be realized stably.
- the optical fiber 10 which is also used as a communication path, is used. Therefore, there is no need to prepare a dedicated sensor for detecting abnormalities in the external environment, which can reduce costs.
- ⁇ Other embodiments> In the above-described first embodiment, only one detector 21 is provided, but the present invention is not limited to this.
- a plurality of detectors 21 may be provided corresponding to a plurality of optical fibers 10, respectively.
- the detector 21 may be connected only to the corresponding optical fiber 10, transmit pulsed light to the corresponding optical fiber 10, and receive an optical signal from the corresponding optical fiber 10.
- the detector 21 may detect only an abnormality in the external environment around the corresponding optical fiber 10, based on the optical signal received from the corresponding optical fiber 10.
- the selection unit 23 selects a communication path based on whether or not an abnormality in the external environment affects the communication path predicted by the prediction unit 22, but this is not limited to this.
- the selection unit 23 may determine the communication capacity during a given communication when the detection unit 21 detects an abnormality in the external environment. The selection unit 23 may then select a communication path based on the presence or absence of an effect of the abnormality in the external environment on the communication path predicted by the prediction unit 22 and the communication capacity determined above. For example, if the communication capacity exceeds the communication capacity of a single optical fiber 10, the selection unit 23 may select multiple optical fibers 10 that are not affected by the abnormality in the external environment as the communication path, or may select a wireless line.
- the selection unit 23 may determine the communication capacity of future communication in a given communication. The selection unit 23 may then select a communication path based on the presence or absence of an influence of an abnormality in the external environment on the communication path predicted by the prediction unit 22 and the communication capacity determined above.
- the selection unit 23 may determine the priority of a predetermined communication when the detection unit 21 detects an abnormality in the external environment. The selection unit 23 may then select a communication path based on the presence or absence of an influence of an abnormality in the external environment on the communication path predicted by the prediction unit 22 and the priority determined above. For example, a high priority may be set for a communication that requires real-time transmission, and a low priority may be set for a communication that does not require real-time transmission. Furthermore, when the priority of a predetermined communication is high, the selection unit 23 may select an optical fiber 10 that is not affected by an abnormality in the external environment as the communication path, in order to select an optical fiber 10 with a high communication speed. Furthermore, when the priority of a predetermined communication is low, the selection unit 23 may select a wireless line via a communication satellite with a low communication speed as the communication path.

前記予測された通信経路への前記異常の影響の有無に基づいて、所定の通信に用いる通信経路として、前記異常の影響を受けない通信経路を選択する選択ステップと、を含む。
まず、図1を参照して、本実施の形態1に係る通信制御システムの構成例について説明する。
図1に示されるように、本実施の形態1に係る通信制御システムは、複数本の光ファイバ10-1~10-n(nは2以上の整数)及び通信制御装置20を備えている。以下、どの光ファイバ10-1~10-nであるかを特定しない場合は、単に「光ファイバ10」と適宜称する。
検知部21には、複数本の光ファイバ10が接続される。
検知部21は、複数本の光ファイバ10の各々にパルス光を送信する。また、検知部21は、複数本の光ファイバ10の各々をパルス光が伝送されることに伴い発生した後方散乱光を、複数本の光ファイバ10の各々から、光信号として受信する。
そのため、選択部23は、通信に用いる通信経路として、外部環境の異常の影響を受けない光ファイバ10-2を選択する。

その後、選択部23は、予測部22により予測された通信経路への外部環境の異常の影響の有無に基づいて、所定の通信に用いる通信経路として、外部環境の異常の影響を受けない通信経路を選択する(ステップS13)。
上述した実施の形態1では、検知部21を1つのみ設けているが、これには限定されない。例えば、複数本の光ファイバ10にそれぞれ対応して、複数の検知部21を設けても良い。この場合、検知部21は、対応する光ファイバ10にのみ接続され、対応する光ファイバ10にパルス光を送信し、対応する光ファイバ10から光信号を受信しても良い。また、検知部21は、対応する光ファイバ10から受信された光信号に基づいて、対応する光ファイバ10の周囲の外部環境の異常のみを検知しても良い。
