Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiments described below are merely examples, and the embodiments to which the present invention is applied are not limited to the following embodiments.

Hereinafter, Examples 1 and 2 will be described as examples of technologies that enable the efficient construction of equipment for providing communication services. In addition, Example 1 and Example 2 can be carried out in combination.

In the following example, transmission of media such as video and audio is given as an example of communication service, but the present invention is applicable to equipment construction of various communication services not limited to media transmission.

(Example 1)
First, Example 1 will be described. Since there are Example 1-1 and Example 1-2 in Example 1, each of them will be described.

<Example 1-1>
<System configuration of Example 1-1>
FIG. 1 is a system configuration diagram of Example 1-1. As shown in FIG. 1, this system has a communication device 100, a DHCP server 40, and a file server 20, and has a configuration in which these are connected to a network 30. The communication device 100 is, for example, a communication device newly installed at a certain base for transmitting media, and is a communication device to which setting information is input.

The DHCP server 40 is a server that receives a request and returns an IP address or the like. The file server 20 is a server that holds setting information to be input to the communication device 100.

In the first embodiment, the setting information is downloaded from the file server 20 to the communication device 100 by the worker (construction person) simply pressing a button provided on the communication device 100, and the setting information is displayed on the communication device 100. Set. Although this method uses a technique called ZTP (Zero Touch Provisioning), the conventional ZTP does not have a mechanism for downloading setting information simply by pressing a button.

FIG. 2 is a configuration diagram of the communication device 100. As shown in FIG. 2, the communication device 100 includes a monitoring control unit 110, a signal processing unit 120, an NW processing unit 130, and a power supply unit 140. The monitoring control unit 110 includes a button 111, a button press detection unit 112, and a setting processing unit 113.

The monitoring control unit 110 monitors each part of the communication device 100 and downloads setting information based on the button press. More specifically, when the operator presses the button 111, the button press detection unit 112 detects the button press and instructs the setting processing unit 113 to start the process for downloading the setting information. Based on the instruction, the setting processing unit 113 performs a process for downloading the setting information, and executes the setting process based on the downloaded setting information.

The signal processing unit 120 executes signal processing such as packetization of a media signal. The NW processing unit 130 executes processing related to connection with the NW. The NW processing unit 130 may be referred to as a NW interface. The power supply unit 140 performs a process for supplying power.

FIG. 3 is a diagram showing an image when the communication device 100 is viewed from the front. As shown in FIG. 3, the monitoring control unit 110 is provided with a button 111. Further, as shown in FIG. 3, each part is housed in a housing as a package. However, such a configuration of the communication device 100 is only an example.

<Operation example of Example 1-1>
An example of the operation sequence in the first embodiment will be described with reference to FIG.

In S101, the operator turns on the power of the communication device 100, and in S102, presses the button 111.

After that, the DHCP sequence (S103 to S106) is executed, so that the communication device 100 acquires the information of the access destination (file server 20). In S107, the communication device 100 transmits a request for acquiring the setting information to the file server 20, and in S108, the communication device 100 acquires the setting information.

<Example 1-2>
Example 1-2 is premised on Example 1-1. That is, the communication device 100 of Example 1-2 has a function described in Example 1-2 in addition to the function described in Example 1-1. However, Example 1-2 may not be premised on Example 1-1.

In Example 1-1 described above, it is necessary to manually create the setting information to be downloaded from the file server 20 in advance. In order to create the setting information, it is usually necessary to grasp the mounting state of the package of the communication device 100, which requires a great deal of time and effort.

Therefore, in the first and second embodiment, when the communication device 100 is started, the monitoring control unit 110 grasps the mounting state of the processing unit (that is, the package) in the communication device 100, and sets the grasped contents in advance. It is reflected in the information (downloaded setting information assuming Example 1-1). This makes it possible to reduce the amount of setting information created in advance.

“Reflect” means, for example, when the setting information requires information on the mounting position of the package A, the information is left blank in the setting information prepared in advance, and the monitoring control unit 110 is in the mounting state. After confirming, enter the relevant information in the blank.

As shown in FIG. 5, the monitoring control unit 110 includes a mounting state acquisition unit 115 and an automatic setting unit 116 as functional units related to reducing the amount of setting information created in advance.

When the communication device 100 is started, the mounting state acquisition unit 115 grasps (acquires) the package mounted on the communication device 100 and the state (insertion position, type, port information, etc.) of the package. For example, in the example of FIG. 5, it is grasped that two packages A, one package B, and one package C are mounted, and the state such as the position of each package is grasped.

The automatic setting unit 116 reflects the grasped physical information about each package (where in the communication device 100 it is mounted, etc.) in the setting information. Further, the automatic setting unit 116 automatically generates a part that can be inferred from the package state (type and usage port information) for the logical setting and usage setting (service-like usage of physical port and specification of logical connection). It can be reflected in the setting information. FIG. 6 shows a conventional design range for setting information and a design range for the communication device 100 of Example 1-2.

If the function of the first or second embodiment is not provided, the worker of the setting information needs to check the mounting state of the package in the communication device 100 and manually reflect the mounting state information in the setting information in advance. On the other hand, by providing the functions of the first and second embodiments, the setting information can be created without including the information based on the mounting state of the package, so that the amount of the setting information can be reduced and the setting information can be created. The effort is also reduced.

(Example 2)
Next, Example 2 will be described. Example 2 is premised on Example 1. That is, the communication device of the second embodiment has the functions described in the second embodiment in addition to the functions of the communication device of the first embodiment. However, Example 2 may not be premised on Example 1.

The second embodiment is related to, for example, a test at the time of opening a line, which is carried out after the setting of the setting information using the technique of the first embodiment is completed.

FIG. 7 is an overall configuration diagram of the system according to the second embodiment. FIG. 7 is common to Examples 2-1 and 2-2, which will be described later. However, the internal configuration of each device may be different between Example 2-1 and Example 2-2.

As shown in FIG. 7, in this system, a plurality of communication devices 200 for transmitting and receiving media are connected by a line (network). Each communication device 200 is connected to the monitoring device 300 via the network 500. Further, a terminal 400 for an operator (NW administrator or the like) to perform an operation is connected to the monitoring device 300.

<Outline of Example 2>
When the line is opened, it is necessary to confirm at least the following (A) and (B).

(A) Media can be transmitted without error.

(B) Being able to confirm the contents of the media.

"Being able to confirm the contents of the media" in (B) means that if the media is an image, a person can see the image and confirm that the image has been transmitted without any problem (the image is not disturbed, etc.). If is a sound, it means that a person can listen to the sound and confirm that the sound has been transmitted without any problem (the sound is not interrupted, etc.). Note that (A) may be referred to as a media continuity test, and (B) may be referred to as a media monitor test.

In the second embodiment, both (A) and (B) can be confirmed remotely from the terminal 400 shown in FIG. Regarding (A), a signal generation / error check mechanism is provided in the communication device 200 to enable remote error check. Regarding (B), the media signal immediately before the input / output is compressed and transmitted to a remote location, for example, so that the remote operator can watch the signal and check the status. In addition, "viewing" in this specification means only watching a video, listening to a sound, or watching a video and listening to a sound.

Hereinafter, the technique for realizing (A) will be described as Example 2-1 and the technique for realizing (B) will be described as Example 2-2. Example 2-1 and Example 2-2 are carried out in combination. However, the combination is not limited, and only Example 2-1 may be carried out, or only Example 2-2 may be carried out.

In any of Examples 2-1 and 2-2, the media signal may be an audio signal, a video signal, or both an audio signal and a video signal. Good.

<Example 2-1>
First, the method (A) described above will be described as Example 2-1. In the method (A), a media signal / test signal input function or a measurement function is provided at a point close to the input / output of the communication device 200 so that a transmission error can be confirmed from a remote terminal 400. There is.

FIG. 8 is a diagram showing a configuration of a communication device 200S on the signal transmitting side and a communication device 200R on the signal receiving side in the second embodiment. FIG. 8 has a configuration in which the communication device 200S on the transmitting side and the communication device 200 (referred to as 200R) on the receiving side are connected by a network 600. Normally, the functional unit in the communication device has an active system and a backup system, but FIG. 8 shows one system in order to show the configuration related to the continuity test in an easy-to-understand manner. The same applies to FIG. 12 of Example 2-2.

Further, in FIG. 8, the communication device 200S on the signal transmitting side and the communication device 200R on the signal receiving side have different configurations, but in reality, the communication device 200S also includes the function of the communication device 200R, and the communication device 200R is included. Also includes the function of the communication device 200S.

As shown in FIG. 8, the transmission side communication device 200S includes an input / output unit 201S, a test signal input unit 210, a packetization unit 202S, and a transmission unit 203S. The functions of each part are as follows.

The input / output unit 201S receives a media signal transmitted from an external user facility or the like, or a test signal transmitted from the test signal input unit 210 (the test signal is a type of media signal), and receives the media signal or the media signal. The test signal (denoted as “media signal / test signal”) is output to the packetizing unit 202S. The test signal input unit 210 generates a test signal based on the instruction from the monitoring device 300, and inputs the test signal to the input / output unit 201S. The generation and input of the test signal do not have to be based on the instruction from the monitoring device 300.

The packetization unit 202S converts the input media signal / test signal into a packet and outputs the packet. The transmission unit 203S outputs the packet to the network 600.

The communication device 200R on the receiving side includes an input / output unit 201R, a measurement function unit 211, a packetization unit 202R, and a transmission unit 203R. The functions of each part are as follows.

The transmission unit 203R receives a packet from the network 600 and outputs the packet to the packetization unit 202R. The packetization unit 202R converts the packet into a media signal / test signal and outputs the packet. The input / output unit 201R outputs the media signal transmitted from the user equipment to the outside, and outputs the test signal to the measurement function unit 211. Further, the input / output unit 201R can output the media signal transmitted from the user equipment to the outside and also output it to the measurement function unit 211.

The measurement function unit 211 transmits the measurement result (example: error rate, delay) of the received media signal / test signal to the monitoring device 300.

In Example 2-1 the media signal / test signal is the object of measurement. As an example, when an audio signal is targeted, the signal flows, for example, as shown in FIG. In this case, in the configuration of FIG. 8, the voice signal (AES frame) is input to the input / output unit 201S, converted into an RTP packet by the packetization unit 202S, and the RTP packet is transmitted from the transmission unit 203S via the network 600. Then, it reaches the transmission unit 203R on the receiving side. The RTP packet is converted into an audio signal (AES frame) by the packetization unit 202R and output from the input / output unit 201R. The output audio signal is input to, for example, the measurement function unit 211, and measurement is performed.

Next, when the media signal is not received from the user equipment as in the opening test, the operation when the test is performed using the test signal will be described with reference to FIG. In addition, this test may be called an OUS (Out of service) test.

For example, an operator operating the terminal 400 inputs information to the terminal 400 to perform a test using a test signal for a section between the communication device 200S and the communication device 200R. The terminal 400 instructs the monitoring device 300 to perform a test using the test signal for the section between the communication device 200S and the communication device 200R.

The monitoring device 300 instructs the test signal input unit 210 of the communication device 200S to generate a test signal and input it to the input / output unit 201S. Further, the monitoring device 300 instructs the measurement function unit 211 of the communication device 200R to measure the test signal sent from the communication device 200S and report the measurement result to the monitoring device 300.

Then, the test signal input unit 210 generates a test signal and inputs it to the input / output unit 201S. The test signal is not limited to a specific signal. As an example, in the case of voice, a pseudo-random pattern (PN pattern) can be used as a test signal.

The test signal reaches the measurement function unit 211 of the communication device 200R on the receiving side. The communication device 200R measures the test signal and notifies the monitoring device 300 of the measurement result. The monitoring device 300 transmits the measurement result to the terminal 400. The measurement result is displayed on the terminal 400, and the operator can confirm whether or not an error has occurred.

Regarding the delay, for example, by adding a time stamp to the test signal on the test signal transmitting side (test signal input unit 210), the receiving side (measurement function unit 211) is delayed due to the difference between the current time and the time stamp. Can be measured.

Next, the operation during the test using the media signal transmitted from the user equipment during the service will be described with reference to FIG. This test is supposed to be done without stopping the service. In addition, this test may be called an INS (In-service) test.

For example, the operator operating the terminal 400 inputs to the terminal 400 information that the section between the communication device 200S and the communication device 200R is to be tested using the media signal transmitted from the user equipment. The terminal 400 instructs the monitoring device 300 to perform a test using the media signal transmitted from the user equipment for the section between the communication device 200S and the communication device 200R.

The monitoring device 300 instructs the input / output unit 201R of the communication device 200R to output the received media signal to the outside and also to the measurement function unit 211. In addition, the measurement function unit 211 of the communication device 200R is instructed to report the measurement result of the media signal to the monitoring device 300.

According to the above instruction, the measurement function unit 211 measures the received media signal and notifies the monitoring device 300 of the measurement result. The monitoring device 300 transmits the measurement result to the terminal 400. The measurement result is displayed on the terminal 400, and the operator can confirm whether or not an error has occurred.

In FIG. 8, a portion for inputting a test signal (eg, a portion of the input / output unit 201S for receiving a signal from the test signal input unit 210) may be referred to as an Insert point. Further, the measurement function unit 211 of the communication device 200R may be called a Monitor point (when measuring a media signal / test signal and passing it through) or a Drop point (when measuring a media signal / test signal and terminating it). Good.

The configuration shown in FIG. 8 is an example, and for example, a test configuration as shown in FIGS. 10 and 11 is also possible. In these figures, I indicates an Insert point (I point), M indicates a Monitor point (M point), and D indicates a Drop point (D point).

In FIG. 10, a test signal is input in the communication device 200-1, and the test signal is measured at points M and D shown in the figure. In the example of FIG. 10, the test signal is folded back in the communication device 200-3. As a result, the round-trip delay can be measured in addition to the error rate and the like.

FIG. 11 shows an example in which the media signal input from the user equipment 250 to the communication device 200-4 is measured at each M point.

<Example 2-2>
Next, the method (B) described above will be described as Example 2-2. In the method (B), the media signal immediately before the input / output is transmitted to the remote monitoring device 300 so that the operator can check the status by viewing the media data.

FIG. 12 is a diagram showing a configuration of a communication device 200S on the signal transmitting side, a communication device 200R on the signal receiving side, and a monitoring device 300 in the second embodiment. FIG. 12 has a configuration in which the communication device 200S on the transmitting side and the communication device 200R on the receiving side are connected by a network 600.

In FIG. 12, the communication device 200S on the signal transmitting side and the communication device 200R on the signal receiving side have different configurations, but in reality, the communication device 200S also includes the function of the communication device 200R, and the communication device 200R is included. Also includes the function of the communication device 200S.

As shown in FIG. 12, the transmission side communication device 200S includes an input / output unit 201S, a packetization unit 202S, a transmission unit 203S, a monitor compression processing unit 220S, and a monitor signal packetization unit 230S. The input / output unit 201S, the packetization unit 202S, and the transmission unit 203S are the same as in the second embodiment.

The communication device 200S on the transmitting side has a branch function (which may be called a branching unit) that transmits the media signal input from the user equipment or the like to the input / output unit 201S and also transmits the media signal to the monitor compression processing unit 220S.

The monitor compression processing unit 220S compresses the received media signal and outputs the compressed signal to the monitor signal packetization unit 230S. It should be noted that compression is not essential, and compression may not be performed.

The monitor signal packetizing unit 230S packets the compressed media signal and inputs it to the transmission unit 203S.

The transmission unit 203S transmits the packet received from the monitor signal packetization unit 230S to the monitoring device 300. In the monitoring device 300, the media data storage unit 310 stores the data of the packet as media data.

The communication device 200R on the receiving side includes an input / output unit 201R, a packetization unit 202R, a transmission unit 203R, a monitor compression processing unit 220R, and a monitor signal packetization unit 230R. The input / output unit 201R, the packetization unit 202R, and the transmission unit 203R are the same as those in the second embodiment.

The communication device 200R transmits the media signal output from the input / output unit 201R (the media signal output from the user equipment and passing through the communication device 200S and the network 600) to the outside, and also transmits the media signal to the monitor compression processing unit 220R. It has a branching function (may be called a branching part).

The monitor compression processing unit 220R compresses the received media signal and outputs the compressed signal to the monitor signal packetization unit 230R. It should be noted that compression is not essential, and compression may not be performed.

The monitor signal packetizing unit 230R packets the compressed media signal and inputs it to the transmission unit 203R.

The transmission unit 203R transmits the packet received from the monitor signal packetization unit 230R to the monitoring device 300. In the monitoring device 300, the media data storage unit 310 stores the packet as media data. That is, the media data storage unit 310 includes media data corresponding to the media signal immediately before being input to the input / output unit 201S on the transmitting side and media corresponding to the media signal immediately after being output from the input / output unit 201R on the receiving side. Stores data.

The control unit 320 of the monitoring device 300 operates according to the operator's instruction sent from the terminal 400.

An example of the operation related to the measurement of the second embodiment will be described with reference to FIG. An operator operating the terminal 400 transmits from the user equipment 250 to the communication device 200S and the communication device 200R on the terminal 400 in order to confirm the state of the line between the communication device 200S and the communication device 200R. Instruct to perform monitoring of media signals.

In S201, the terminal 400 transmits a monitor start instruction to the communication device 200S and the communication device 200R to the monitoring device 300. In S202, the control unit 320 of the monitoring device 300 transmits a monitor start instruction to each of the communication device 200S and the communication device 200R.

The communication device 200S and the communication device 200R each compress and packetize the media signal by the method as described above, and transmit the packet as media data to the monitoring device 300 (S203). The media data is stored in the media data storage unit 310.

After that, for example, when the operator instructs the terminal 400 to view the media on the input side and the media on the output side, the instruction is sent to the monitoring device 300 as a media data acquisition instruction.

The control unit 320 of the monitoring device 300 acquires the media data on the transmitting side and the media data on the receiving side from the media data storage unit 310 and transmits the media data to the terminal 400. The operator can check, for example, whether or not the line has been normally opened by viewing the media data on the transmitting side and the media data on the receiving side, respectively.
