TECHNICAL FIELD OF THE INVENTION
The present invention relates to a maintenance operation support device that is connected to a device to be monitored and controlled and a terminal provided for the monitoring and control, and that delivers commands and messages to be transmitted and received between the device and the terminal. .
[0002]
[Prior art]
2. Description of the Related Art In recent years, many exchanges and wireless stations have been installed and operated unattended by using switches, transmission devices, and wireless devices to which advanced information processing technology and digital transmission technology have been applied.
For these exchanges, transmission devices, and wireless devices, monitoring of operation status at a maintenance and operation center connected via a communication link and control adapted to the operation status are performed automatically or manually. It is performed appropriately.
[0003]
FIG. 9 is a diagram illustrating a configuration example of the maintenance operation support device.
In the figure, a maintenance operation support device 70 includes a processor 71, communication ports 72, 73-1 to 73-N connected to the processor 71, and an external storage device 74. The communication port 72 is connected to the communication ports of the exchanges 76-1 to 76-n to be monitored and controlled via the network 75, and the communication ports 73-1 to 73-N are connected to the communication links 77-1 respectively. To the communication ports of the terminals 78-1 to 78-N which are provided for the monitoring and control via .about.77-N.
[0004]
In the maintenance and operation support apparatus 70 having such a configuration, as shown in FIG. 10, the main memory of the processor 71 is activated under an operating system 71S having a queue 71Q and under task management performed by the operating system 71S. A communication control task 71T-1 (hereinafter, referred to as “CCT”) and a message / command processing task 71T-2 (hereinafter, referred to as “MCT”) are stored in advance as load modules.
[0005]
Note that solid and dotted arrows shown in FIG. 10 indicate “task activation” and “information flow”, respectively, and the operating system 71S described above has a communication port 72 according to a system call issued by the CCT. A communication driver that physically drives 73-1 to 73-N is included.
When there is no processing to be performed by activating the MCT as described below, the processor 71 performs the resource management as appropriate by executing the operating system 71S.
[0006]
However, some "command" (FIG. 10 (1)) is received via the communication ports 73-1 to 73-N, or a "response" to the "command" via the network 75 and the communication port 72, or an exchange. When a “message” (FIG. 10 (2)) indicating the operating status of any of the communication ports 73-1 to 73-n is received, the processor 71 (the operating system 71S) transmits these communication ports 73-1 to 73-n. The CCT is activated according to the interrupt factor given by N and 72 (FIG. 10 (3)).
[0007]
In the process of executing the CCT, the processor 71 selects one of the above-mentioned “command”, “response”, and “message” (hereinafter, simply referred to as “data”) received via the communication driver described above. Then, a system call (hereinafter, shown with an identifier "QSTT" attached) meaning "starting the MCT using the" data "as a starting factor" is issued (FIGS. 10 (4) and (5)).
[0008]
The processor 71 restarts the execution of the operating system 71S in response to the system call QSTT. In the course of the execution, the processor 71 connects the above-mentioned activation factor "data" to the queue 71Q (FIG. 10 (6)). If there is a task having a higher priority than the MCT at that time (hereinafter, referred to as “priority task”), “first processing” required to activate the priority task or to resume the execution is performed.
[0009]
However, when there is no such a priority task and there is an MCT whose execution has been interrupted by activating the CCT as described above, the processor 71 continues the processing of the MCT by referring to the “second processing”. "I do.
Furthermore, when there is no above-mentioned priority task and there is no MCT whose execution has been interrupted, the processor 71 determines whether or not any “data” is connected to the queue 71Q during the execution of the operating system 71S. Is determined, and if the result of the determination is true, a "third process" for starting the MCT with "data" connected first to the queue 71Q as a start factor is performed (FIG. 10 ( 7)).
[0010]
In addition, as a procedure of processing to be performed by the processor 71 in the process of executing the MCT, a system call (hereinafter, indicated by an identifier “END”) indicating that the processing is completed is defined.
The processor 71 recognizes that the processing of the MCT has been completed in the execution process of the operating system 71S started by issuing such a system call END, and performs the “first processing” based on the above-described procedure. Or “task management” for performing any of the “third processing”.
[0011]
By the way, in the process of the MCT which is activated as described above and in which the processing can be continued, the processor 71 performs an analysis based on a predetermined model for the "data" given as the activation factor. Determines the destination.
Further, the processor 71 “requests transmission of subsidiary data such as a form generated by performing predetermined processing on the“ data ”described above or the“ data ”for the destination” and completing the processing. (Hereinafter, shown with an identifier "SND") (FIG. 10 (8)).
[0012]
In the following, it is assumed that such a system call SND also serves as the above-described system call END for simplicity.
The processor 71 resumes the execution of the operating system 71S in response to the system call SND. In the course of the execution, the processor 71 is provided as an argument of the system call SND among the communication ports 72, 73-1 to 73-N. The corresponding "data" or subsidiary data is transmitted to one of the exchanges 76-1 to 76-n and the terminals 78-1 to 78-N via the communication port corresponding to the destination and the communication driver described above. (FIGS. 10 (9) and (10)).
[0013]
In the external storage device 74, a combination of items assigned in advance to the terminals 78-1 to 78-N among the items of monitoring and control to be performed for the exchanges 76-1 to 76-n are registered in advance as a database. Is done.
[0014]
The processor 71 appropriately refers to the database in order to determine a destination based on the result of the above-described analysis.
Therefore, with regard to the exchanges 76-1 to 76-n, the above-described series of processing is performed in the maintenance operation support device 70 which is opposed via the network 75, so that the monitoring control relating to the desired item is performed by the terminals 78-1 to Of the 78-N, the item is appropriately performed in the course of operation via a terminal assigned in advance.
[0015]
The communication control adapted to the network 75 and the communication links 77-1 to 77-N, and the communication between the maintenance operation support device 70, the exchanges 76-1 to 76-n, and the terminals 78-1 to 78-N at the time of starting and the like. The call setting and connection establishment to be performed between them are performed under the cooperation of the communication driver and the operating system 71S described above. However, as for the procedure of the process performed in the process of the call setting and the connection establishment, various known techniques can be applied and are not related to the present invention, so the description thereof is omitted here.
[0016]
In addition, the contents of the above-described database are appropriately updated by the processor 71 in accordance with the “command” given by the terminals 78-1 to 78-N and the parameters attached to the “command”. However, the procedure of the processing related to such updating is not related to the present invention, and thus the description thereof is omitted here.
[0017]
[Problems to be solved by the invention]
By the way, in such a conventional example, all "commands", "messages" and "responses" are connected to a single queue 71Q as described above, and first-in first-out is performed via the queue 71Q. It is processed sequentially in a manner.
[0018]
Therefore, for example, when a large amount of “message” generated due to the occurrence of a failure or the like is given via the network 75, the processing of the “command” given by the terminals 78-1 to 78-N is: There is a possibility that the processing is started with a considerable delay until the processing relating to these “messages” is completed.
[0019]
However, in such a state, most of the “commands” should be given immediately to the exchanges 76-1 to 76-n in response to the above-mentioned troubles and the like, so that smooth maintenance and operation are hindered. However, there is a possibility that unnecessary time and man-hours are required for the recovery process.
Further, of the “message” and the “response” given via the network 75, for the “message” or the “response” to which only one of the terminals 78-1 to 78-N is allocated, the communication port If a failure occurs in the communication port or communication link corresponding to one of the terminals 73-1 to 73-N and the communication links 77-1 to 77-N, no notification is sent to the person in charge of maintenance and operation. Could be missing without having to do so.
[0020]
When any of the communication ports 73-1 to 73-N or the communication links 77-1 to 77-N is restored to a normal state, the corresponding one of the terminals 78-1 to 78-N is used. For a process in which the terminal is effectively incorporated into a part of the system configuration again, a predetermined operation must be performed on any of these terminals 78-1 to 78-N.
Therefore, when there are many tasks to be performed in parallel for maintenance operation, or when the staff operating the terminals 78-1 to 78-N is insufficient or absent, messages and "responses" are unnecessary. Could be missing.
[0021]

[0034]
The difference between the present embodiment and the conventional example is2As shown as a comparison between FIG. 10 and FIG. 10, the following software configuration is incorporated in the processor 71.
In the main memory of the processor 71, an operating system 51S having two queues 51Q-1 and 51Q-2, and a communication control task 51T-1 (hereinafter simply referred to as a task) started under task management performed by the operating system 51S. "CCT-R"), a command response processing task 51T-2 (hereinafter simply referred to as "CRPT"), and a message processing task 51T-3 (hereinafter simply referred to as "MPT") are loaded in advance. Stored as a module.
[0035]
The figure2Arrows indicated by solid lines and dotted lines respectively indicate "start of task" and "flow of information", and the operating system 51S has a communication port in response to a system call issued by the CRPT and MPT as described later. 72, 73-1 to 73-N.
Also, regarding the correspondence between this embodiment and the block diagram shown in FIG. 1, the exchanges 76-1 to 76-n correspond to the devices 11-1 to 11-n, and the queue 51Q-1 is the first queue. Corresponding to queue 12 and third queue 21, terminals 78-1 to 78-N correspond to terminals 13-1 to 13-N, queue 51Q-2 corresponds to second queue 14, The network 75 corresponds to the transmission path 15, the CCT-R corresponds to the sorting means 16 and 22, the CRPT corresponds to the command processing means 17 and 23 and the response processing means 25, and the MPT corresponds to the message processing means 18 and 24. I do.
[0036]
Below2The operation of the present embodiment corresponding to the first to third aspects of the present invention will be described with reference to FIG.
When there is no target to be processed by activating the CRPT and the MPT, the processor 71 performs the resource management as appropriate by executing the operating system 51S.
[0037]
However, some “command” (see FIG.2(1)) is received or a "response" to the "command" via the network 75 and the communication port 72, or a "message" indicating the operating status of any of the exchanges 76-1 to 76-n (FIG.2When (2)) is received, the processor 71 activates the CCT-R via the operating 51S according to the interrupt factor given by these communication ports 73-1 to 73-N, 72 (FIG.2(3)).
[0038]
In the process of executing the CCT-R, the processor 71 fetches any of the above-mentioned “command” and “response” received through the above-described communication driver (hereinafter, simply referred to as “data CR”). Issue a system call (hereinafter, shown with an identifier "QSTT" attached) which means "to activate CRPT using the" data CR "as an activation factor" (FIG.2(4), Figure3(1)).
[0039]
Further, in the process of executing the CCT-R, the processor 71 takes in any one of the above-mentioned “messages” (hereinafter simply referred to as “data M”) received via the communication driver described above, and “ Activate the MPT using the "data M" as an activation factor "(hereinafter, denoted by the identifier" QSTT ").2(5), Figure3(2)).
[0040]
The processor 71 resumes the execution of the operating system 51S in response to the system call QSTT. In the course of the execution, the processor 71 connects the above-mentioned activation factor "data CR" to the queue 51Q-1 (see FIG.2(6)) and "Data M" is connected to the queue 51Q-2 (see FIG.2In addition to (7)), if there is a task with a higher priority than CRPT and MPT at that time (hereinafter referred to as “priority task”), the first processing required to activate or resume execution of the priority task I do.
[0041]
However, if there is no such priority task and there is a CRPT or MPT whose execution has been interrupted by the activation of the CCT-R as described above, the processor 71 continues the processing of the CRPT or MPT. Perform "second processing".
In addition, if there is no CRPT or MPT whose execution has been interrupted in addition to the priority task described above, the processor 71 connects some “data” to the queue 51Q-1 during the execution of the operating system 51S. If the result of the determination is true, the CRPT is activated using the “data CR” connected first to this queue 51Q-1 as the activation factor. Process ”(Figure2(8)).
[0042]
In addition, when there is no CRPT or MPT whose execution has been interrupted and no “data CR” is connected to the queue 51Q-1, the processor 71 sets the operating system 51S In the process of execution, it is determined whether or not any “data M” is connected to the queue 51Q-2. If the result of the determination is true, the connection to the queue 51Q-1 is made first. A “fourth process” for starting the MPT using the obtained “data M” as a start factor is performed (FIG.2(9)).
[0043]
By the way, as a procedure of processing to be performed by the processor 71 in the process of executing the CRPT and the MPT, a system call (hereinafter, denoted by an identifier “END”) indicating that the processing is completed is defined.
The processor 71 recognizes that the processing of the CRPT or MPT has been completed in the execution process of the operating system 51S started by issuing such a system call END, and based on the above-described procedure, Perform “task management” that performs any of the four processes.
[0044]
By the way, in the process of the CRPT process which is activated as described above or in which the process can be continued, the processor 71 analyzes the “data CR” given as the activation factor based on a predetermined model. By doing so, the destination is determined.
Further, the processor 71 requests “the above-mentioned“ data CR ”for the destination or the transmission of subsidiary data such as a form generated by performing a predetermined process on the“ data CR ”, and completes the process. Issue a system call SND indicating that2(10), Figure4(1), (2)).
[0045]
The processor 71 resumes the execution of the operating system 51S in response to the system call SND. In the course of the execution, the processor 71 is provided as an argument of the system call SND among the communication ports 72, 73-1 to 73-N. Via the communication port corresponding to the destination and the communication driver described above, the corresponding “data CR” or subsidiary data is transmitted to any of the exchanges 76-1 to 76-n and the terminals 78-1 to 78-N. Send (Figure2(11)).
[0046]
The processor 71 is activated as described above, or in the course of the MPT processing in which the processing can be continued, performs an analysis based on a predetermined model for the “data M” given as the activation factor. This determines the destination.
Further, the processor 71 requests “the above-described“ data M ”for the destination or transmission of subsidiary data such as a form generated by performing a predetermined process on the“ data M ”, and completes the process. Issue a system call SND indicating that2(12), Figure5(1)).
[0047]
The processor 71 resumes the execution of the operating system 51S in response to the system call SND. In the course of the execution, the processor 71 sends the communication port 73-1 to 73-N to a destination given as an argument of the system call SND. The corresponding “data M” or subsidiary data is transmitted to any of the terminals 78-1 to 78-N via the corresponding communication port and the communication driver described above (FIG.2(13)).
[0048]
That is, "commands" to be transmitted from the terminals 78-1 to 78-N to the exchanges 76-1 to 76-n, and processing performed by these exchanges 76-1 to 76-n in accordance with the "commands" The "response" to be given to the terminals 78-1 to 78-N as a result of the above is similarly processed by the CRPT in preference to the "message" sent voluntarily by the exchanges 76-1 to 76-n. .
[0049]
Therefore, according to the present embodiment, even when the exchanges 76-1 to 76-n generate a large number of "messages" due to the occurrence of a failure or the like, the failure is dealt with as compared with the conventional example. Therefore, an effective "command" is immediately transmitted to the corresponding exchange.
In the present embodiment, the database registered in the external storage device 74 is appropriately referred to by the processor 71 when determining a destination based on the result of the analysis described above, as in the conventional example. The detailed procedure of the process related to the reference is not relevant to the present invention, and the description thereof is omitted here.

Regarding the magnitude relation of these priorities, both the “command” and “response” described above or When either one should be processed with priority, it may be appropriately updated.
Further, in the present embodiment, the processing of the “command” and the “response” described above are performed in parallel by the CRPT. For example, for the “command” and the “response”, the waiting corresponding to each individually is performed. A queue may be formed by the operating system 51S, and the processing procedure may be defined as different tasks individually corresponding to these queues.
[0052]
Further, in the present embodiment, the operating system 51S that supports the above-described system calls QSTT, SND, and END is applied to the application system. However, equivalent functions are provided for such operating systems and system calls. Any type may be used as long as it is provided and a desired responsiveness is ensured.

FIG.Another form of the inventionFIG. 3 is a diagram showing an embodiment corresponding to FIG.
In the figure, components having the same functions and configurations as those shown in FIG. 9 are denoted by the same reference numerals, and description thereof is omitted here.
[0062]
The difference of the hardware configuration between the present embodiment and the conventional example shown in FIG. 9 is that the maintenance operation support device 62 having the communication port 61 in addition to the communication ports 72, 73-1 to 73-N is different from the maintenance operation support device. 70, and terminals 78a-1 to 78a-N instead of terminals 78-1 to 78-N. These terminals 78a-1 to 78a-N have communication links 77A-1 to 77A, respectively. -N, and the configuration is the same as that of the maintenance and operation support device 62, and is connected via the bidirectional interlink 63 between the communication port 61 and the network 75. The point is that a connected maintenance operation support device 62A is provided.
[0063]
Note that, for simplicity, the components of the maintenance and operation support device 62A are indicated by adding a suffix “A” to the end of the reference numerals of the corresponding components of the maintenance and operation support device 62. It is omitted.
In addition, this embodiment and FIG.6The exchanges 76-1 to 76-n correspond to the devices 31-1 to 31-n, the network 75 corresponds to the transmission line 32, and the terminals 78a-1 to 78a-n Correspond to the terminals 33-1 to 33-N, the communication links 77-1 to 77-N and 77A-1 to 77A-N correspond to the communication link 34, and the communication ports 73-1 to 73-N and 73A- 1 to 73A-N and the processors 71 and 71A correspond to the communication link monitoring means 35, the interlink 63 corresponds to the confounding communication link 36, the communication ports 61 and 61A correspond to the confounding interface means 37, and the processors 71 and 71A. Are detour means 38, transfer means 39, self-system restoration notifying means 41,ReturnCorresponds to the old request means 42.
[0064]
First, it is assumed that the communication links 77-1 to 77-N and 77A-1 to 77A-N are adapted to the RS-232C system for simplicity.
In the maintenance operation support device 62, the processor 71 performs handshaking with the terminals 78a-1 to 78a-1 at predetermined frequencies via the communication ports 73-1 to 73-N and the communication links 77-1 to 77-N. By doing so, it is determined whether or not these communication ports 73-1 to 73-N and communication links 77-1 to 77-N are operating normally (see FIG.5(a)).
[0065]
In addition, about such a handshake, for example,
(1) a process of monitoring a logical value of the “data channel reception carrier detection signal CD”;
(2) Along with the process of setting or updating the "data terminal ready signal ER" based on a predetermined procedure, and synchronizing with the process, the logical value of the "data set ready signal DR" is changed. Process to monitor
However, as long as the above-described determination is made with a desired accuracy, the present invention may be applied to any transmission method and communication procedure.
[0066]
Further, the processor 71 sends the result of the determination individually obtained for the communication links 77-1 to 77-N in the process of the handshake to the maintenance operation support device 62A via the communication port 61 and the interlink 63. .
In the maintenance operation support device 62A, since a series of processes performed in the maintenance operation support device 62 as described above are performed in parallel, the details of the processes are omitted.
[0067]
In the maintenance operation support devices 62 and 62A, the processors 71 and 71A perform the same handshake with each other via the communication ports 61 and 61A and the interlink 63, respectively, so that the communication link is established via the interlink 63. It is determined whether or not it is formed normally (Fig.5(b)).
Further, in the maintenance operation support device 62, the maintenance operation support device 62 operates as the active system, and the maintenance operation support device 62A operates as the standby system, so that the duplex system based on the standby redundancy system is normally configured. During this period, the processor 71 determines, for example, that some kind of failure has occurred in the communication link 77-K (K = 1 to N) among the communication links 77-1 to 77-N in the above-described processing procedure. If the terminal 78a-K is identified on the basis of the message 78a-K, the identification information of the terminal 78a-K is added to the "message" and "response" to be sent to the terminal 78a-K via the communication link 77-K. By performing the respective processes, a “transfer message” and a “transfer response” are generated.
[0068]
Further, the processor 71 sequentially sends out these “transfer message” and “transfer response” to the interlink 63 via the communication port 61 (FIG.5(c)).
On the other hand, in the maintenance operation support device 62A, the processor 71A sequentially takes in the above-mentioned “transfer message” and “transfer response” from the interlink 63 via the communication port 61A, and converts the “transfer message” and “transfer response” By performing processing opposite to the above-described conversion processing, the identification information of the terminal 78a-K is restored together with the corresponding “message” and “response”.
[0069]
Further, the processor 71A communicates with the terminal 78a via the communication port and the communication link corresponding to the identification information thus restored among the communication ports 73A-1 to 73A-N and the communication links 77A-1 to 77A-N. Send the restored "message" or "response" to -K together with the identification information.
In addition, the terminal 78a-K also operates as a target of the process related to the monitoring control regarding the “message” and the “response” given via any of the communication links 77-K and 77A-K.
[0070]
That is, of the working communication links 77-1 to 77-N (77A-1 to 77A-N), the failed communication link 77-K (77A-K) is formed under the common use of the interlink 63. Communication route 77A-K (62A) formed between the terminal 78a-K connected to the communication link 77-K (77A-K) and the standby operation and maintenance support device 62A (62). 77-K).

In the maintenance and operation support device 62, for example, after a certain failure occurs in the communication link 77-K, the processor 71 has already exchanged with the terminal 78a-K facing the communication link 77-K at a predetermined frequency. By performing the above-described handshake, it is determined whether or not these communication ports 73-1 to 73-N and communication links 77-1 to 77-N have been restored to a normal state (FIG. 8A).
[0073]
Further, the processor 71 sends the result of the determination to the maintenance operation support device 62A via the communication port 61 and the interlink 63 (FIG. 8 (2)).
On the other hand, in the maintenance and operation support device 62A, the processor 71A performs the reverse conversion process of the “transfer message” and the “transfer response” during the period when the maintenance and operation support device 62A is operating as the standby system, thereby obtaining the “message”. And the response are restored (FIG. 8 (3)), and among the communication links 77A-1 to 77A-N, the communication links 77A-K to which these "messages" and "responses" are sent are sent. Is identified (FIG. 8 (4)).
[0074]
Further, the processor 71A determines that among the determination results given via the interlink 63, the determination result corresponding to the communication link 77-K paired with the communication link 77A-K has been changed from false to true. If it is recognized, it generates a "recovery notification" to that effect and sends this "recovery notification" to the terminal 78a-K via the communication link 77A-K (FIG. 8 (5)).
[0075]
Further, when the terminal 78a-K recognizes such a "recovery notification", the terminal 78a-K mutually communicates with the maintenance and operation support device 62 via the communication link 77-K based on the same procedure as at the time of start-up. Perform establishment.
That is, the communication link 77-K in which the failure has occurred is replaced via the previously described detour, but is promptly put into service without manual intervention when the communication link 77-K is restored.
[0076]
Therefore, according to the present embodiment, the efficiency and accuracy of maintenance and operation are lower than that of the conventional example, in which the operator of the terminal 78a-K or another person who is involved in maintenance and operation is required for such recovery. Enhanced.

When the software is tightly coupled to the hardware forming the call, these call setting and connection setting need not be performed again.
[0079]
