  The user IF unit 110 provides, for example, a Web screen to a user (user terminal) so that the user can input information. The application processing unit 120 acquires migration application information from the user via the user IF unit 110 and stores the information in the data storage unit 150. The application information includes, for example, the identification information of the user and the scheduled switching date and time.

  The connection determination unit 130 receives information (may be called trap information) transmitted from each device, and determines a connection state based on the trap information.

  The operation control unit 140 controls a switching operation described later. The data storage unit 150 stores various information such as the above-described application information and setting information necessary for operation (eg, optical characteristic information for each device type at the user's home).

  The control device 100 can be realized by executing a program corresponding to a process performed by the control device 100 using hardware resources such as a CPU and a memory built in the computer. The above-mentioned program can be recorded on a computer-readable recording medium (a portable memory or the like) and can be stored or distributed. Further, the above program can be provided through a network such as the Internet or electronic mail.

(Example of connection determination logic)
In the switching operation in the communication system according to the present embodiment, the connection determination unit 130 of the control device 100 determines the connection state of the device at the user's home side. Here, an example of the connection determination logic will be described. .

  As described above, the light visualization PP 310 can detect an optical signal transmitted from the user's home side and notify the control device 100 of the optical signal as an electric signal. The notification of the optical signal as an electric signal is an example, and the optical signal may be notified as it is. An electric signal or an optical signal notified from the light visualization PP 310 to the control device 100 will be referred to as a notification signal.

  The light visualization PP 310 that has received the optical signal transmitted from a certain user home device transmits a notification signal about the user home device, and the connection determination unit 130 of the control device 100 receives the notification signal.

  The connection determination unit 130 identifies the optical characteristics (eg, frequency, blinking period) of the optical signal transmitted from the user home-side device from the notification signal, and based on the optical characteristics, determines the user who transmitted the optical signal. It is possible to identify whether the home device is an existing device or a new device. For this identification, for example, by storing the optical characteristics of the optical signal received from the existing device in the past in the data storage unit 150, and comparing the optical characteristics with the optical characteristics of the optical signal to be determined, realizable. In addition, the optical characteristics are stored in advance in the data storage unit 150 for each maker, each device type, each device version, and the like, and the optical characteristics of the optical signal to be determined are compared with the stored optical characteristics. May be used for identification.

  In addition, the connection determination unit 130 of the control device 100 determines that the central office apparatus has detected trapping light from the user home side apparatus, and that the central office apparatus can communicate with the user home side apparatus. Is received from the station apparatus.

  Based on these pieces of information, the connection determination unit 130 can perform the connection determination using, for example, the logic illustrated in FIG. Note that the logic illustrated in FIG. 5 is merely an example. In addition to the logic illustrated in FIG. 5, for example, the connection determination may be performed only from the light visualization PP 310 using the notification signal. Hereinafter, the example of FIG. 5 will be described.

  As illustrated in FIG. 5, the connection determination unit 130 determines that the existing device 210 is connected on the user home side based on, for example, a notification signal from the light visualization PP 310, and Based on the trap information, the station-side existing device 330 detects the received light from the user home-side existing device 210 and determines that communication with the user home-side existing device 210 is possible. It is determined that the existing device 210 is connected to the station-side existing device 330.

  Further, for example, based on the notification signal from the light visualization PP 310, the connection determination unit 130 determines that the existing device 210 is connected on the user home side, and uses the trap information from the office side existing device 330 as the trap information. If the station-side existing device 330 detects the received light from the user-home-side existing device 210 but determines that communication is not possible based on this, the pattern is not applicable in the normal system, so N / A (Not applicable). In this case, since it is assumed that a failure or a failure has occurred, the failure may be determined.

  Further, for example, based on the notification signal from the light visualization PP 310, the connection determination unit 130 determines that the existing device 210 is connected on the user home side, and uses the trap information from the office side existing device 330 as the trap information. When it is determined that the existing office device 330 on the premises side does not detect the received light from the existing device 210 on the user's home based on the base device, the existing device 210 on the user home side is not connected to the existing device 330 on the premises side. (That is, a state where the connection in the Robo PP 320 is not established).

  Further, for example, based on the notification signal from the light visualization PP 310, the connection determination unit 130 determines that the new device 220 is connected on the user home side, and uses the trap information from the station building existing device 330 as the trap information. On the basis of this, when the station-side existing device 330 detects the received light from the user house-side existing device 210 but determines that communication is not possible, the new user house-side device 220 connects to the station-side existing device 330. Judge that you are.

  Here, it is assumed that the office-side existing device 330 can detect the optical signal from the user home-side new device 220, but cannot communicate with the user home-side new device 220 due to a difference in optical characteristics or the like. ing. However, the connection determination unit 130 determines that the new device 220 is connected on the user home side based on the notification signal from the light visualization PP 310, and based on the trap information from the station-side existing device 330. Even when the office-side existing device 330 detects the received light from the user home-side new device 220 and determines that communication is possible, the user-home-side new device 220 is connected to the office-side existing device 330. May be determined.

(Example of switching operation)
In the case where the existing user apparatus 210 on the user home side is switched to the new apparatus 220 on the user home side by migration, and the apparatus on the office side communicating with the apparatus on the user home side is switched from the existing apparatus 330 on the office side to the new apparatus 340 on the office side An operation example will be described along the procedure shown in FIGS.

<Step 1: FIG. 6>
In step 1, as shown in FIG. 6, the user applies for device migration from a portal screen or the like displayed by the user IF unit 110 of the control device 100. The application information includes the identification information of the user and the scheduled switching date and time, and these are stored in the data storage unit 150. The operation control unit 140 determines that the existing device 210 on the user home side of the user is switched to the new device 220 on the user home side based on the identification information of the user, performs NW design based on the determination, and as a result, Is stored in the data storage unit 150. The result of the NW design includes, for example, connection switching information in the Robo PP 320. The connection switching information is, for example, information indicating that the existing connection “user-side port A-station device-side port X” is switched to connection “user-side port A-station device-side port Y”.

  Further, the operation control unit 140 transitions to a migration waiting state. The migration waiting state is to wait until the current time of the user becomes “scheduled switching date and time”. As shown in FIG. 6, until the switching operation is started, the main signal flows between the existing user apparatus 210 and the existing station apparatus 330.

  When the current time reaches the “scheduled switching date and time”, the processing after step 2 is performed.

<Step 2: FIG. 7>
In step 2, as shown in FIG. 7, the user removes the existing device 210 on the user home side. That is, the existing device 210 on the user home side is removed from the line (optical fiber) extending from the office building.

  As a result, the light visualization PP 310 does not detect the light signal from the existing device 210 on the user home side, and issues a notification signal (alarm) indicating that. In addition, since the office-side existing device 330 also does not detect the optical signal from the user-home-side existing device 210, it issues trap information (alarm) indicating the fact. The connection determination unit 140 of the control device 100 receives these warnings, determines that the existing user device 210 has been disconnected, and notifies the operation control unit 140 of the determination result.

<Step 3: FIG. 8>
In Step 3, as shown in FIG. 8, the user attaches the new user home-side device 220. That is, the new user home-side device 220 is connected to a line (optical fiber) extending from the office building. Thereby, the optical visualization PP 310 receives the optical signal from the new user home-side device 220 and transmits a notification signal indicating that the optical signal has been received to the control device 100. Further, the station-side existing device 330 detects trapping light from the new user-home-side device 220, but transmits trap information indicating that communication is not possible to the control device 100.

  The connection determination unit 130 of the control device 100 determines that the new device 220 is connected on the user home side based on the notification signal from the light visualization PP 310, and uses the trap information from the station building existing device 330 Based on the base station existing device 330 detects the received light from the user home side new device 220 but determines that communication is not possible, the user home side new device 220 connects to the Can be determined to be. The result of the determination is notified to the operation control unit 140.

<Step 4: FIG. 9>
In step 4, the operation control unit 140 that has detected that the new user home-side device 220 has been connected performs switching of the connection to the Robo PP 320 so that the new user home-side device 220 and the measuring device 350 are connected. Instruct.

  As shown in FIG. 9, the Robo PP 320 performs connection switching according to the instruction, and the new user home-side device 220 and the measuring device 350 are connected. Further, the operation control unit 140 instructs the measuring device 350 to execute the opening test, and the measuring device 350 executes the opening test. Here, the light visualization PP 310 detects a light signal flowing along with the opening test, and issues a notification signal to the control device 100. The operation control unit 140 can recognize that the opening test is being performed based on the notification signal.

  Here, the opening test by the measuring device 350 is successful, and information indicating the success is sent to the operation control unit 140 of the control device 100. Accordingly, the operation control unit 140 recognizes that the transmission path between the new user home-side device 220 and the station building has been opened. When the opening is grasped, the process proceeds to step 5.

<Step 5: FIG. 10>
In step 5, the operation control unit 140 that has detected that the opening test for the new user home device 220 is successful connects the new user home device 220 and the new office building device 340 to the Robo PP 320. To switch connection.

  As shown in FIG. 10, the Robo PP 320 performs connection switching according to the instruction, and the new user home device 220 and the new office building device 340 are connected. In addition, the operation control unit 140 inputs, to the station building-side new device 340, settings necessary for communication with the user home-side new device 220. If settings have already been entered or new settings need not be entered, the settings may not be entered here.

  The light visualization PP 310 receives an optical signal flowing between the new user home-side device 220 and the new office side device 340, and transmits a notification signal indicating that the optical signal has been received to the control device 100. In addition, the office-side new device 340 detects the light received from the user-home-side new device 220 and transmits to the control device 100 trap information indicating that communication is possible. From these pieces of information, the operation control unit 140 of the control device 100 can grasp that the switching has been completed and the service provision by the device after the migration has started.
