FIG. 1 is a block diagram showing a configuration of an embodiment of a detour information collection system in a PBX network management system according to the present invention. In the example of FIG. 1, a manager (data network management system) 10 that performs network management control, an agent (data relay station) 20 that executes instructions from the manager 10 and controls a PBX 30, and is accommodated in the agent 20. The PBX 30 is roughly configured.

The manager 10 has a user interface (I / F) unit 11 for performing interface processing with an administrator.
And a compiler unit 12 for compiling a management operation program, and a manager I / F unit 13 for controlling communication between the manager 10 and the agent 20. The compiler section 12 compiles the source code and the parameters of the management operation, and thereby executes a script 25 between the manager 10 and the agent 20.
(Shown in the agent 20) is used to reduce the amount of data to be transmitted.

The agent 20 includes a manager / agent I / F unit 21 for receiving a script 25 from the manager 10 and an agent I / F unit 23 for transmitting an instruction converted into data receivable by the PBX 30.
And a management operation unit 24 for storing classes defining operations, and a management operation unit 24
And an interpreter 22 for dynamically linking the script 25 and realizing the actual management operation.

The PBX 30 is connected to the agent 20 and the PBX.
A PBXI I / F unit 31 for performing signal control between the PBX I / F 30 and
A data memory 32 for storing or reading data through the PBXI I / F unit 31 is provided.

Next, the operation of this embodiment will be described. FIG. 2 is a flowchart showing a processing procedure of the operation of this embodiment, and FIG. 3 is a diagram showing an outline of a script in the PBX network management system.

The manager 10 fetches source code and parameter management operation information input from the management operator through the user I / F unit 11 (step S1). Management operation information (source code, parameters) from the user I / F unit 11 is input to the compiler unit 12, where it is compiled and compiled into an intermediate language script (script) 1.
Is created (step S2).

Next, the script (script) 1 from the compiler unit 12 is sent from the manager I / F unit 13 to the agent 20 (step S3). As shown in FIG. 3A, this script (script) 1 has a function name indicating collection of detour information and the like, and PBs of a calling station and a called station.
A parameter indicating X, an operation content indicating a detour to the called station, and a next station (PBX) designation as a variable are stored.

In the agent 20, for the script 1 received from the manager 10 by the manager / agent I / F unit 21, a class defining the management operation requested by the management operation is extracted from the management operation unit 24. The link is dynamically linked by the interpreter 22 and the processing is executed.

In this case, if data in the PBX 30 is required, the data is collected by accessing the data memory 32 of the PBX 30. This access is performed through an interface process between the agent I / F unit 23 of the agent 20 and the PBX I / F unit 31 in the PBX 30 (step S4).

If it is determined from the analysis result in the agent 20 that the management operation is necessary for another agent (step S5: Yes), a new script (sc) in which the management operation and the analysis result are written is written.
generate) / manager / agent I /
The data is transmitted to the next agent (not shown) through the F unit 21 and the process returns to step S4.
Then, an access is made to the device 2 and its data is collected (step S6).

The script (script) 2 in this case
As shown in FIG. 3B, a function name indicating detour information collection and the like, a parameter indicating a PBX of a calling station and a called station, an operation content indicating a detour of a called station, and designation of a next station (PBX) The next station designation as a variable and the output result 1 of the bypassing PBX are stored.

When all necessary operations between agents have been completed, that is, when it is determined that the management operation is not necessary for another agent (step S5: N)
o), the final agent sends the script (script) 3 in which the final result is written to the manager (step S7). The script in this case (script
t) 3 includes a function name indicating detour information collection, a parameter indicating a PBX of a calling station and a called station, an operation content indicating a detour of a called station, and a next station specification as a variable for specifying a next station (PBX). , And the detour PBX output result 1... Result N are stored.

Then, only the result is notified to the management operator (step S8). For this reason, the irrelevant agent does not perform any operation.
Since only the result is notified without performing the analysis processing, efficient network management in the PBX network management system becomes possible without increasing the processing load on the manager 10.

Next, a detailed operation of collecting detour information according to this embodiment will be described. FIG. 4 is a diagram illustrating a network configuration in collecting detour information, and FIG. 5 is a diagram illustrating script contents in collecting detour information.

The network configuration shown in FIG. 5 is obtained by networking the manager 10, the agent 20, and the PBX 30 shown in FIG. 1. Agents 20a, 20b, 20c, 20d are connected to the manager 10 respectively. This agent 20a-20d
The PBXs 30a, 30b, 30c, 30d are respectively connected by communication lines.

Next, the operation of collecting detour information in this network will be described. The manager 10 sends the detour information acquisition request information from the management operator to the user
The source code and parameters are fetched through the unit 11 and sent to the compiler unit 12. This compiler part 1
In FIG. 5A, the source code and parameters are compiled to reduce the amount of data between the manager 10 and the agent, and the source code and parameters are set to an intermediate code (intermediate language).
A script (script) A shown in FIG.

In this script (script) A, the function name is detour information collection, and the parameter is the originating station PBX-
a (30a) and the receiving station PBX-c (30c) are stored. If the operation content is PBX-c (3
0c) indicates a detour when the call arrives, and stores that the next station designation as a variable is PBX-a (30a).

As shown in FIG. 4, the script A is transmitted from the manager I / F unit 13 of the manager 10 to the agent 20a of the transmitting station through the route 1. The agent 20a receives the script (script) A from the manager 10 at the manager / agent I / F unit 21 and manages the received script (script) A with the management operation unit 24.
Class that defines the operation for actually obtaining the detour information from is dynamically linked and processed.

Further, the data is converted into data that can be processed by the PBX 30a by the agent I / F unit 23 in the agent 20a. After that, the agent I / F unit 23 in the agent 20a requests the PBX 30a to acquire the detour information. In the PBX 30a, the PBX I / F unit 31
Receives the request for the detour information, reads the detour data for the PBX 30c of the called station from the data memory 32, and stores the detour data in the PBX I / F in the PBX 30a.
It is returned to the agent 20a through the unit 31.

The agent I / F unit 23 in the agent 20a having received the response from the PBX 30a
PBX which is the next detour destination data read from 30a
30b is a new script (scri) shown in FIG.
pt) Write as a variable of B and as information passed through the PBX 30a.

In this script (script) B, the function name is detour information collection, and the parameter is the originating station PBX.
-A (30a) and the receiving station PBX-c (30c) are stored. Also, if the operation content is PBX-c
(30c) indicates a detour when a call arrives, and stores that the next station designation as a variable is PBX-b (30b). Further, when the output is the first detour, PBX-a
(30a) is stored.

This script (script) B is the manager / agent I / F unit 2 in the agent 20.
Passed to 1. Manager / agent I / F unit 21
Transmits a script (script) B to the next agent 20b via the path 2. The same operation processing as before is repeated up to the PBX 30c of the receiving station. In this operation processing, the agent I / F unit 23 of the agent 20c determines that the PBX 30c is the receiving station.

Agent I of this agent 20c
The result information of the detour determined by the / F unit 23 is the PBX 30
The agent D / F unit 23 of the agent 20c notifies the manager / agent I / F unit 21 of a script D that stores a → PBX 30b → PBX 30c.

The script D has a function name of detour information collection and a parameter of originating station PBX-a.
(30a) and the destination station PBX-c (30c) are stored. The operation content is PBX-c (30
c) indicates a detour for an incoming call, and stores that the next station designation as a variable is PBX-c (30c). Further, the output is PBX-a (3
0a), the PBX-b (30b) as the second station is stored, and the PBX-c (30c) as the last station is stored.

The manager / agent I / F unit 21 of the agent 20c transmits a script D in which the result information of the detour is stored to the manager 10 through the route 4. In this case, the agent 20d
Instead, the detour information is sent to the manager 10 without passing through, and the collection of the detour information is terminated.

That is, the manager 10 has not collected management information from all the agents 20a to 20d.
That is, the irrelevant agent 20d does not operate, and the manager 10 does not perform the unnecessary analysis processing. As a result, efficient network management such as changing relay information and closing an agent route for a congestion state and a signal loop abnormality can be performed without increasing the communication processing load on the manager 10.

[0043]

As is apparent from the above description, according to the detour information collection method in the PBX network management system of the present invention, the script information created by the manager for the management operation is transmitted between the manager and the agent. Further, the information is transmitted and received between agents, and the manager collects the detour information based on the management information.

Therefore, when the manager collects the detour information from the management information including the congestion state and the loop abnormality obtained from the agent accommodating the exchange, the manager does not need to collect the management information from all the agents and has no relation. Agents do not need to take any action.

As a result, since the manager collects the detour information only based on the notification result without performing unnecessary analysis processing, the communication processing load on the manager does not increase, and the congestion state and the signal loop are reduced. Efficient network management such as change of relay information for abnormalities and closing of agent routes becomes possible.
