Abstract

PURPOSE:To smoothly and efficiently execute a desired processing within a system by continuing the communication of the requirement and the result of the processing even when a fault is generated in a line connected to an external device or an exchange housing the line. CONSTITUTION:When a processing requirement addressed to another exchange incomes from the external device TM1, the system transfers it to another exchange EX3 by respectively adding identification information of a communication line connecting the external device TM1 of a requiment source and that of its own exchange. Another exchange EX3 executes a processing corresponding to the transferred processing requirement and then, recognizes the exchange EX 1 of the transfer source from identification information added to the processing requirement so as to send back the processing result to the exchange EX1 of the transfer source. Then, the exchange EX1 to which the processing result is sent back recognizes the external device TM1 of the processing requirement source from communication line identification information added to the processing result and outputs the processing result to the external device TM1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distributed exchange system in which a plurality of private branch exchanges are connected via a communication line.

[0002]

2. Description of the Related Art In a distributed switching system, for example, in a company having a plurality of branch offices or sales offices, a private branch exchange is installed in each of the above-mentioned branch offices or sales offices, and a communication line such as a dedicated line is provided between these private branch exchanges. It is connected through. In this type of system, it is possible not only to perform inter-extension communication and external call / outgoing for each private branch exchange, but also to perform extension communication between different private branch exchanges and external call / outgoing via different exchanges.

By the way, in this kind of distributed exchange system, an external device such as a call management device has recently been connected to an arbitrary private branch exchange, and the call charges are selectively aggregated from the external device to each private branch exchange in the system. It has been considered to have a function of sending a predetermined processing request such as a request, causing each private branch exchange to perform a predetermined processing, and returning the processing result data to the external device. In order to realize this kind of function, conventionally, for example, the address of the extension to which the external device is connected and the address of the private branch exchange that accommodates this extension are registered in advance in each private branch exchange, and the processing result data is sent to the request source. When returning to the external device, the exchange and extension to which the requesting external device is connected are recognized based on the registered address.

However, in the conventional system of this type, for example, when a fault occurs in an extension to which an external device is connected or a private branch exchange accommodating the extension, a processing request using the external device is taken until the fault is recovered. Cannot be sent and the processing result data cannot be received. Also, each time a system change such as a number plan change or an exchange addition is made, it is necessary to re-register the address setting in each private branch exchange, which requires a lot of time and labor for maintenance.

On the other hand, in a distributed exchange system, in general, each private branch exchange stores in advance operational data of the entire system together with operational data of the individual exchanges, and based on these operational data, the individual exchange operation and the operation of the entire system are performed. Is configured to run. Therefore, when adding an exchange or upgrading the version of a system, it is necessary to take over existing operation data and then make necessary corrections to the operation data.

Conventionally, the modification of the operation data is distributed in each exchange, for example, and the existing operation data is read, and a data setting request is created based on these operation data. Then, the operation data for all the systems is manually edited based on these data setting requests.

Therefore, it takes a lot of time and labor to correct the operation data, and most of the correction work is performed manually, so that a human error often occurs. This problem becomes more remarkable as the scale of the system becomes larger, which is extremely undesirable.

[0008]

As described above, according to the conventional system, when an external device is used to cause an arbitrary exchange in the system to perform desired processing, a line to which the external device is connected or this line is connected. When a failure occurs in the private branch exchange that accommodates the system, there is a problem that the processing request and processing result data cannot be collected by the external device at all until the failure is recovered, and it takes a lot of time and labor to change the system. Was.

Further, when the existing operation data is taken over and the operation data is corrected, there is a problem that the correction work requires a lot of time and labor and human error is likely to occur. .

Therefore, a first object of the present invention is to reconnect the external device to another line or switch even if a failure occurs in the line to which the external device is connected or the switch accommodating this line. It is an object of the present invention to provide a decentralized exchange system which enables transmission and reception of processing requests and processing results to be continuously performed, whereby desired processing in the system can be efficiently executed without delay.

A second object of the present invention is to provide a distributed exchange system capable of easily and quickly modifying operation data and reducing human error as much as possible. Is.

[0012]

In order to achieve the first object, a first invention is to connect a plurality of exchanges via a first communication line and at least one of the exchanges. Is connected to an external device via the second communication line, the processing request input from the external device is transferred to the transfer destination exchange, and the processing according to the request content is performed, and the processing result is transferred to the exchange. In a distributed exchange system having a function of returning to the external device via an external device, in each of the exchanges, when a processing request is input from the external device via the second communication line, a first identification information giving unit. Thus, the first identification information for identifying the second communication line to which the external device is connected and the second identification information for identifying the own exchange are added to the processing request, respectively. 1 and The second identification information is given processing request, and transfers the processing request transmitter via the first communication line to the destination exchange. Further, when the processing request is transferred through the first communication line, the processing according to the processing request is executed by the processing execution means, and the processing result obtained by the processing execution means is added to the above processing. The first identification information given to the request is given by the second identification information giving means, and the processing result provided with the first identification information is given to the processing request by the processing result returning means. When the processing result output means returns the processing result to the transfer source exchange through the first communication line based on the received second identification information, and the processing result is returned through the first communication line. The processing result is output to the requesting external device through the second communication line based on the first identification information added to the processing result.

On the other hand, in order to achieve the above-mentioned second object, the second invention has a plurality of exchanges connected to each other through a communication line, and based on operation data stored in advance by these exchanges. A function to execute a predetermined exchange operation,
In a distributed switching system having a function of connecting a maintenance terminal device to each of the exchanges and performing a maintenance process of the operation data, the maintenance data of the operation data is distributed to the exchanges by the maintenance terminals. A distributed maintenance processing means, a centralized maintenance processing means for centrally performing maintenance processing of operational data on the respective exchanges by an arbitrary maintenance terminal among the maintenance terminals, and a maintenance processing selection means,
The distributed maintenance processing means and the centralized maintenance processing means are selectively selected and executed by the maintenance processing selection means. Based on the output request distribution transmitting means for transmitting the operation data output requests in accordance with the predetermined output request rules, and the operation data sent from the exchange in response to the operation data output request, the respective maintenance terminals have predetermined The setting request distribution generating means for generating and accumulating the operation data setting request corresponding to the function of the corresponding exchange according to the data conversion rule, and the operation data setting request generated and accumulated by the setting request distribution generating means Setting request decentralized input means for sending from the maintenance terminal to the corresponding exchanges respectively, and the exchanges in response to the operation data output request. The operation data collected by the operation data collection means for collecting the operation data sent from an arbitrary maintenance terminal, and the operation data of each exchange collected by this operation data collection means, together with the operation data common to each exchange according to a predetermined classification judgment rule. An operation data classifying unit for classifying into the operation data of each exchange, and an operation data editing unit for editing and storing the operation data for each of the common operation data and individual operation data classified by this operation data classifying unit are provided. And the centralized maintenance processing means is an output request centralized transmission means for transmitting an operation data output request from the arbitrary maintenance terminal to each exchange via the communication line in accordance with a predetermined output request rule. , Based on the operation data sent from each of the exchanges via the communication line in response to the operation data output request, In the maintenance terminal, the setting request centralized generating means for respectively generating and accumulating the operational data setting request corresponding to the function of each exchange according to the predetermined data conversion rule, and the operation generated and accumulated by the centralized setting request centralizing means It is characterized by further comprising setting request centralized input means for transmitting a data setting request to each of the exchanges via the communication line.

[0014]

As a result, according to the first aspect of the invention, the exchange to which the processing request is transferred can recognize the exchange to which the processing result is to be returned from the identification information given to the processing request. Therefore, it is not necessary to register in advance the identification information of the exchanges to which the external devices are connected and the lines of the exchanges in each exchange. Therefore, even if a failure such as disconnection occurs in the communication line to which the external device is connected, or even if the private branch exchange main unit to which the external device is connected cannot be used due to a runaway, etc. Alternatively, by reconnecting to the exchange, it becomes possible to continuously send the processing request and receive the processing result.
Further, even if the numbering plan is changed or the system is changed such as the addition of an exchange, it is not necessary to re-register the address settings in each exchange, which simplifies the maintenance work of the system. .

On the other hand, according to the second aspect of the present invention, the distributed maintenance processing and the centralized maintenance processing are selectively selected by the maintenance processing selecting means and executed. Here, in the above distributed maintenance processing, although it is necessary to collect and edit the operation data read from each exchange, it is relatively short because the generation processing of the operation data setting request is performed in parallel in each exchange. Processing can be completed in time. On the other hand, in the centralized maintenance process, the process of generating the operation data setting request is sequentially performed in a time-divisional manner for each exchange, so the processing time is relatively long, but it is not necessary to edit the operation data. Therefore, it is possible to efficiently generate data by selectively using the distributed maintenance process and the centralized maintenance process according to the amount of data to be generated.

Further, in the distributed maintenance processing in which the maintenance data is distributed from the respective maintenance terminals to the respective exchanges, the maintenance data can be concentrated on the respective exchanges from any maintenance terminal among the maintenance terminals. Even in the centralized maintenance process for performing the maintenance process of the operation data, all the series of processes are automatically performed without human intervention. Therefore, the maintenance process of the operation data can be performed without much time and labor, and the occurrence of human error is significantly reduced.

In the processing request analysis device 12, as shown in step 1a, it is determined whether the processing request is to be processed by the own exchange or transferred to another exchange. Now, it is assumed that the processing request should be processed by the own exchange EX1. Then, according to the instruction from the process request control device 13, the process request processing device 15 performs a predetermined process according to the content of the process request (step 1c). Then, the processing result is transferred from the processing request control device 13 to the external input / output device 11, is sent from the external input / output device 11 to the external device TM1 which is the call request source, and is displayed on the display (step 1d). ).

On the other hand, it is assumed that the processing request is addressed to another exchange. In this case, the processing request control device 13 sends the processing request to the external device T that is the transmission source of the processing request.

Processing request control device 33
Then, the transferred processing request information is separated into processing request and identification information, and the processing request is notified to the processing request processing device 35 (step 3a). The processing request processing device 35 executes a predetermined processing according to the processing request (step 3b).

When the processing result is obtained by this execution, in the processing request control device 33, one of the two pieces of identification information included in the identification information separated from the processing request information, that is, the communication line to which the external device TM1 is connected. Identification information is added to the processing result. Then, the private branch exchange EX1 of the transfer source is recognized from the other information of the two pieces of identification information included in the identification information separated from the processing request information, that is, the exchange identification information (step 3c).
The processing result data is returned from the other exchange communication device 34 to the communication line WL toward X1 (step 3d). FIG. 5 shows an example of the structure of this processing result data, in which communication line identification information is added to the head of the processing result.

When the processing result data arrives, in the private branch exchange EX1, the processing result control device 13 separates the processing result data into the processing result and the identification information, and the external device TM1 as the request source is recognized from the identification information. (Step 1g). Then, according to this recognition result, the above-mentioned processing result is sent from the external input / output device 11 to the external device TM1 which is the processing request source, and is displayed on the display (step 1h).

As described above, in this embodiment, the external device TM1 is used.
When a processing request addressed to another exchange is received from the other exchange, the identification information of the communication line to which the requesting external device TM1 is connected and the identification information of the own exchange are added to the processing request and the other exchange EX3 is added. After the transfer, the other exchange EX3 executes the process according to the transferred process request, and then the exchange EX of the transfer source uses the identification information added to the process request.
1 is recognized and the processing result is returned to the exchange EX1 of the transfer source, and the exchange EX1 which has returned the processing result recognizes the external device TM1 of the processing request source from the communication line identification information added to the processing result. Then, the processing result is output to the external device TM1.

That is, in each private branch exchange, when returning the processing result, the exchange and the external device of the return destination can be recognized from the identification information added to the processing request, so that the external device TM1 is connected. It is not necessary to register the identification information of the existing communication line and private branch exchange in advance.

Therefore, even if a failure such as a disconnection occurs in the communication line to which the external device TM1 is connected, the external device TM1 is connected to another idle communication line of the same exchange EX1 to continue processing request. It is possible to send and receive processing results. Even if the private branch exchange body to which the external device is connected becomes unusable due to a runaway or the like, the external device TM1 is connected to another private branch exchange EX3 as shown in FIG. It is possible to send and receive processing results. Further, even if the numbering plan is changed or the system is changed such as the addition of exchanges, it is not necessary to re-register the address settings in each private branch exchange, which simplifies the maintenance work of the system. it can.

Next, the operation data correction operation in the system configured as described above will be described. (1) When creating operation data setting requests by distributing to each private branch exchange PBX1 to PBXn In the operation data setting devices HM1 to HMn connected to the private branch exchanges PBX1 to PBXn, maintenance personnel specify the distributed processing mode. After that, it is assumed that an operation data setting request generation start instruction is input. Then, in the operation data setting devices HM1 to HMn, the operation control devices MC1 to M
First, the operation data read control is executed by Cn. In this operation data read control, there are cases where one read procedure is defined for one operation data and cases where a plurality of read procedures are defined for one operation data. In the following description, the operation data setting device HM1
A case will be described as an example where the operation data of the private branch exchange PBX1 is read.

First, when one reading procedure is defined for one operation data, the operation control device MC1
10 shows the operation data read procedure 1 corresponding to the operation data 1 to be read as the second operation data management table M.
An operation data output request for reading from the G12 and reading the operation data 1 is generated in accordance with the rule shown in the operation data reading procedure 1. Then, this operation data output request is sent to the corresponding private branch exchange PBX1.

On the other hand, in the private branch exchange PBX1, when an operation data output request comes from the operation data setting device HM1, the central controller XC1 follows the operation data output request and the mounting memory XN1 or the external storage device XM1.
Operation data 1 is read from. Then, it is judged whether or not the operation data 1 is normally read out, and if it is normally read out, the operation data 1 is sent to the operation data setting device HM1 as a request source in accordance with a predetermined format. It should be noted that if an error occurs in the reading, an error notification is sent to the operation data setting device HM1.

In the operation data setting device HM1, when the operation data 1 is sent from the private branch exchange PBX1, the operation control device MC1 judges whether or not this operation data 1 is normal, and if normal, the second operation data management According to the operation data setting procedure 1 stored in the display MG12, the operation data setting request for the other private branch exchanges PBX2 to PBXn having different functions is generated from the operation data 1 setting information 1 included in the operation data 1. .

On the other hand, when a plurality of reading procedures are defined for one operation data, the operation control device MC1
Is the second operation data management table MG1 as shown in FIG.
The operation data read procedure 1 corresponding to the operation data 2 to be read is first read from 2 and an operation data output request for reading the operation data 2 is generated in accordance with the rule shown in the operation data read procedure 1. Then, this operation data output request is sent to the corresponding private branch exchange PBX1.

On the other hand, in the private branch exchange PBX1, when an operation data output request comes from the operation data setting device HM1, the central controller XC1 follows the operation data output request and the mounted memory XN1 or the external storage device XM1.
Operation data 2 is read from. Then, it is judged whether or not the operation data 2 is normally read out, and if it is normally read out, the operation data 2 is sent to the operation data setting device HM1 of the request source according to a predetermined format. It should be noted that if an error occurs in the reading, an error notification is sent to the operation data setting device HM1.

In the operation data setting device HM1, when the operation data is sent from the private branch exchange PBX1, the operation control device MC1 judges whether this operation data 2 is normal, and if it is normal, it is included in the above operation data 2. The operating data 2 setting information 1 is stored in the memory in the control device or the external storage device MM.

Thus, each operation data setting device HM1 to HM1
Private branch exchanges PBX1 to PBX by HMn dispersion processing
An operation data setting request for n is generated.

By the way, in the case of the distributed processing mode, it is necessary to edit the operational data common to all the systems. That is, each of the operation data setting devices HM1 to HM
The operation data collected in n is stored in the external storage device MM.
After being read from 1 to MMn, the second communication line WL
2 to the operation data setting device HMm for editing processing. In the operation data setting device HMm, when the operation data comes from each of the operation data setting devices HM1 to HMn, the control device MCm temporarily stores the operation data in the external storage device MMm. Then, according to the determination rule stored in the first operation data management table MGm1,
The operation data collected from each of the operation data setting devices HM1 to HMn is classified into operation data common to all private branch exchanges and operation data individual to each private branch exchange, and operation data common to all private branch exchanges for each of these classifications. Edit the operation data for each private branch exchange.

(2) In the case where an arbitrary private branch exchange centrally generates operation data setting requests for all private branch exchanges PBX1 to PBXn In this case, for example, as shown in FIG. 12, an arbitrary private branch exchange PBX1 is connected. The operation data setting device HM1 is used as a device for data collection.

That is, it is assumed that, in the operation data setting device HM1, the maintenance staff designates the centralized processing mode and then inputs an operation data setting request generation start instruction. Then, in the operation data setting device HM1, the operation control device MC
First, 1 executes the transmission process of the operation data output request. In the operation data output request transmission procedure, the operation data output request is transmitted to the private branch exchanges PBX1 to PBXn for each operation data setting procedure, and the operation data output request is transmitted to each of the private branch exchanges PBX.
In some cases, an operation data output request for each operation data setting procedure from operation data 1 to operation data n is sent for each 1 to PBXn.

First, when the operation data output request is sent to the private branch exchanges PBX1 to PBXn for each operation data setting procedure, the operation control device MC1 corresponds to the operation data 1 to be read as shown in FIG. The operation data read procedure 1 is read from the second operation data management table MG12, and an operation data output request for reading the operation data 1 is generated according to the rule shown in the operation data read procedure 1. Then, the operation data output request is sequentially sent to each of the private branch exchanges PBX1 to PBXn via the first communication line WL1.

On the other hand, each private branch exchange PBX1 to PBX
In n, when an operation data output request from the operation data setting device HM1 arrives, the central control devices XC1 to XCn follow the operation data output request and mount memories XN1 to XN.
The operation data is read from Nn or the external storage devices XM1 to XMn. Then, it is determined whether or not the operation data has been normally read, and if normally read, the operation data is sent to the requesting operation data setting device HM1 according to a predetermined format. It should be noted that if an error occurs in the reading, an error notification is sent to the operation data setting device HM1.

That is, the operation data output request from the operation data setting device HM1 to the private branch exchanges PBX1 to PBXn and the operation data transmission from the private branch exchanges PBX1 to PBXn to the operation data setting device HM1 are performed by the first operation. The time division multiplexing is performed on the communication line WL1.

In the operation data setting device HM1, when operation data is sent from each of the private branch exchanges PBX1 to PBXn,
The operation control device MC1 determines whether or not these operation data are normal, and if normal, the second operation data management display MG
According to the operation data setting procedure 1 stored in 12,
An operation data setting request is generated from the operation data setting information 1 included in the operation data. Then, the above processing is repeated from the operation data 1 to the operation data n.

On the other hand, when the operation data output request for all the operation data setting procedures from operation data 1 to operation data n is sent for each private branch exchange PBX1 to PBXn,
The operation control device MC1 uses the operation data read procedure 1 corresponding to the operation data 1 to be read as the second operation data management table M.
An operation data output request for reading from the G12 and reading the operation data 1 is generated in accordance with the rule shown in the operation data reading procedure 1. Then, this operation data output request is sent to the private branch exchange PBX1.

On the other hand, when the operation data 1 is sent from the private branch exchange PBX1, the operation control device MC1 judges whether this operation data 1 is normal, and if normal, it is stored in the second operation data management display MG12. An operation data setting request is generated from the operation data 1 according to the operation data setting procedure 1 and is stored in the external recording device.

The operation data setting device HM1 repeatedly executes the above procedure for the operation data 1 to the operation data n by the operation control device MC1, whereby the private branch exchange P
When all the operation data from the BX1 are collected, all the above-mentioned procedures for the operation data 1 to the operation data n are executed for the next private branch exchange PBX2. Thereafter, the same procedure is repeatedly executed for the remaining private branch exchanges PBX3 to PBXn each time a series of operation data collection procedures for the above-mentioned operational data 1 to operational data n is completed for one private branch exchange.

Thus, the operation data setting device HM1 collects the operation data of all the private branch exchanges PBX1 to PBXn, and generates the operation data setting request based on the collected operation data.

The operation data setting request generated as described above or the operation data setting request accumulated in the external storage device is transmitted to each of the private branch exchanges PBX1 to PBX1 to PBX1 having a different function.
The procedure for loading into PBXn is as follows:
There are two types, one is distributed among X1 to PBXn, and the other is concentrated from any private branch exchange to each private branch exchange PBX1 to PBXn.

In the case of distributed input, the operation data setting devices HM1 to HMn respectively correspond to the private branch exchanges PB.
An operation data setting request is sent to X1 to PBXn, and each private branch exchange PBX1 to PBXn sets new operation data in response to the sent operation data setting request.

On the other hand, in the case of centralized input, from the operation data setting device HM1 to the private branch exchanges PBX1 to PBXn.
To each of the private branch exchanges PBX1 to PBX, the operational data setting request is sent via the first communication line WL1.
In n, new operational data is set in response to the sent operational data setting request.

As described above, in the system according to the present embodiment, the operation data setting devices HM1 to HMn distribute the operation data to the private branch exchanges PBX1 to PBXn and set the operation data. A centralized maintenance processing procedure for centrally performing operation data setting processing on each of the private branch exchanges PBX1 to PBXn by any one of the operation data setting apparatuses HM1 to HMn, and selecting these procedures according to mode designation. I'm trying to run it. Therefore, depending on the amount of data you generate,
Data can be efficiently generated by selectively using the distributed maintenance processing and the centralized maintenance processing.

Further, according to this embodiment, the operation data setting devices HM1 to HMn are used to output the private branch exchanges PBX1 to PBX.
Also in the distributed processing in which the operation data setting processing is distributed to BXn, the operation data setting devices HM are also used.
1 to HMn, a series of processes are automatically performed without any human intervention even in the centralized processing in which the operation data setting device HM1 concentrates the operation data setting process on each of the private branch exchanges PBX1 to PBXn. Will be done. Therefore, the maintenance process of the operation data can be performed without much time and labor, and the occurrence of human error can be significantly reduced.

The present invention is not limited to the above embodiments. For example, in the second embodiment, both the distributed maintenance processing function and the centralized maintenance processing function are provided and these functions are selectively executed. However, when the system is constructed, either one of the functions, for example, the centralized maintenance function, is executed. It is also possible to provide only the processing function and to add the other function, for example, the distributed maintenance processing function, when an exchange or the like is added later. By doing so, it is possible to reduce the financial burden on the user when the system is constructed, and it is possible to improve the efficiency of maintenance processing of the operation data after the system is added.

In addition, the configuration of external devices and maintenance terminals,
The types and configurations of the exchanges, the transfer procedure of the processing request and the processing result, the generation procedure of the operation data output request and the operation data setting request, and the like can be variously modified and implemented without departing from the scope of the present invention.
