Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for selecting and determining a function executing node associated with a communication network operating system.

[0002] Here, the communication network operation system is intended to provide a communication service to a communication service customer quickly and stably, and to a communication service provider, to efficiently operate and maintain the communication network. The research and development have been active in recent years.

The communication network operation business is complicated and diversified depending on the object and purpose, such as communication facility support, communication network support, and service support. As an example of such an operation business, the service order business, which is an operation business for newly providing a communication service to a customer, will be described with reference to the service order business. Business is started by applying for.

[0004] Then, the determination of the telephone number and the type of additional service, the selection of the terminal, the registration in the exchange, the determination of the communication route from the station to the customer's communication terminal and the laying of the communication line, the registration for charging, the failure history Data registration for management, confirmation test of various devices for service start, etc. (these are referred to as operation functions) are performed in a defined order, so that the final purpose of providing the service is Done. Here, the operation function is
An operation function executing entity (such as an operator) receives an operation function execution request source (such as a construction order), and can be arranged as an action to apply an operation to an operation target (such as a switch) using an operation means (such as OpS).

The operation work is composed of various forms of operation functions, and the operation work can be abstracted as a whole in which a set of operation functions has an order relation. Operation control system (PCS) prototyped by the inventors
Manages data related to operation work classified based on the above method of organizing operation work.

Operation control system (P
The concept of CS) will be briefly described. The integrated operation means (OpS) using the PCS is composed of a PCS main body for controlling the operation work and an operation function executing entity which is the main body for executing the operation function. The operation function executing entity is an operation means (OpS) for controlling the network element (NE), a work instruction terminal for instructing the operator to perform a work, a DBMS for managing data such as network configuration data, and the like.

In the present invention, a function execution command is issued to an operation system and a work instruction system for an operator (the operation system as a function execution node for executing a plurality of distributed and identical functions and a work instruction system for an operator). Regarding the function execution node selection determination method for allocating data, particularly when the commands for executing the same function are concentrated in a short period of time, from the transmission status of the function execution command data to the function execution node,
The present invention relates to a function execution node selection and determination method of selecting and determining a function execution node that minimizes the waiting time for function execution and transmitting function execution command data to the function execution node.

[0008]

2. Description of the Related Art Conventionally, in a system in which various functions for processing a work are distributed and arranged, as a method for controlling the execution of the work, the operation process control system described above (Oyamada, Takahashi, if details are required) "Business integrated control system for realizing flow-through operation-operation process control system-" NTT R & D Vol.41, No.6, (1992).) Has been proposed.

In the conventional operation process control system, the method of transmitting the function execution command data to the function execution node is as follows: the process execution control unit in the operation process control system instructs the function execution command to execute the function. This is a method of creating data and transmitting the function execution command data to the function execution node address (operation system, work instruction system, etc.) set in the function execution command data. Further, there is usually only one function execution node address that executes the same function.

The conventional operation process control method is described in detail in "Operation process control method" (Japanese Patent Laid-Open No. Hei 02-93972) and the above-mentioned references, so refer to it if necessary. .

[0011]

The above-mentioned conventional method has the following problems. That is, in the conventional method, there is only one node that sends specific function execution command data from the process execution control unit and executes it, and there is no choice. Therefore, when a plurality of function execution command data is sent, the function execution node to which the specific function execution command data is sent from the process execution control unit executes the function according to the received order.

For this reason, even if the operation target to be executed by the function execution node is free, the function execution node can execute the function only sequentially, so that the processing time at the function execution node is long. , Could be a bottleneck in the overall processing. Further, in the execution of functions, there are objects that do not have an operation target, and since such processing has also been executed sequentially in the past, there are meaningless and useless operations in the sequential execution, and However, there is a problem that the overall processing efficiency of is low.

An object of the present invention is to overcome the above-mentioned problems of the prior art and to shorten the processing time at the function executing node to eliminate the bottleneck of the entire processing and to improve the overall processing efficiency of the work. (EN) Provided is a method for selecting and determining a function execution node in an operation process control system.

[0014]

In order to achieve the above object, according to the present invention, a plurality of function execution nodes such as an operation system that divides a communication network operation task into individual execution functions and executes the respective execution functions, In an information processing system including a process control system including an execution control unit for sending an execution command of an execution function to the function execution node,

The process control system is provided with a selection determining unit for a function execution node to which the execution command is to be sent, and an execution status management table for managing the function execution status in each of the plurality of function execution nodes. It was

[0016]

[Operation] The execution control unit that created the function execution command data
When the execution instruction data is passed to the selection determination unit, the selection determination unit should refer to the execution status management table and select the function execution node whose execution status is relatively empty and send the execution instruction data. It decides the other party and sends the execution command data, and at the same time, writes that fact in the column of the function execution node of the management table, and the function execution node receives the execution command, executes it, and returns a message to that effect. Then, the selection determining unit receives it and cancels the contents previously written in the column of the function executing node of the management table.

By doing so, it is possible to select a function execution node in a relatively free situation from a plurality of function execution nodes provided and send out the execution command data to be executed. The efficiency of business processing can be improved.

[0018]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an information processing system to which a function execution node selection determining method according to an embodiment of the present invention is applied.

In the figure, 1 is a process control system for controlling the execution of processes when executing operation tasks, 2 is a process execution control unit for controlling the operation processes, and 3 is a function of the operation system. The function execution node selection control unit 10 for transmitting the function execution command data to the node to be operated is a data transfer network.

Reference numerals 11, 12A, 12B, 12C and 12D denote communication data transmission / reception control units, 20A, 20B and 2 respectively.
0C and 20D are operating system, 21
Reference numerals A, 21B, 21C and 21D are operation function execution control units, and 22A and 22C are network elements.

FIG. 2 is a block diagram showing details of the function execution node selection control unit 3 in FIG. In FIG. 2, 31 is an execution node address determination unit, and 32 is a node address selection information database as an execution status management table.

The outline of the operation in FIG. 1 is as follows. When the process execution control unit 2 in the process control system 1 passes (transmits) the function execution command data to the function execution node selection control unit 3, the function execution node selection control unit 3 causes the execution node address determination unit 31 in FIG. Will receive this.

Now, it is assumed that the operation system for executing the received function execution command may be either 20A or 20B. The node address selection information database 32 of FIG.
The execution status of B (the status of empty blockage and the degree of blockage) is managed. That is, the node address selection information database 32 can be called an execution status management table.

Therefore, the execution node address determining unit 31
Referring to the node address selection information database 32,
Select an operating system that is in a relatively leisure situation, and access the operating system (for example, 20A) via the communication data transmission / reception control unit 11, the data transfer network 10, and the communication data transmission / reception control unit 12A. The function execution command data is transmitted.

At the same time, the execution node address determination unit 3
1 writes in the node address selection information database 32 that the operation system 20A has been selected (closed) in this way. On the other hand, the operation system 20A executes the transmitted function execution command, and returns the execution result data to the execution node address determination unit 31 through the same route.

Then, the execution node address determination unit 31 erases the contents (that the operation system 20A has been selected and blocked) previously written in the node address selection information database 32 by receiving this, and The execution result data received with is transmitted to the process execution control unit 2 in FIG. The above is the outline of the operation.

FIG. 3 is a flow chart summarizing the processing flow of each unit in FIG. 1 outlined above. Further, FIGS. 4 to 6 are explanatory diagrams particularly showing the state of changes over time in the processing flow (in particular, changes in the contents of the node address selection information database 32). Hereinafter, the function executing node selection determining method according to the present invention will be described in detail with reference to FIGS. 1 to 6 again.

First, in the operation process control system 1 of FIG. 1, it is assumed that the execution of the same function is concentrated when a plurality of operation jobs are controlled in parallel. It is assumed that the function execution command data is passed from the process execution control unit 2 to the function execution node selection control unit 3 in order to execute the function in a certain work (step 201 in FIG. 3).

An image at that time is shown at 301 in FIG. An arrow 307 represents the function execution command data 307, which is passed from the process execution control unit 2 to the function execution node selection control unit 3. 303 (Op
1-A), 304 (Op1-B), etc. correspond to the operation systems 20A, 20B, etc. in FIG.
302 Op1 is 303 (Op1-A) to 306 (Op
1-D) belong to the same group, and belong to the same group 303 (Op 1-A) to 306 (Op).
FIG. 4 shows that the execution status of 1-D) (the status of the degree of air blockage or the degree of blockage) is managed by 32 on the right side.

Next, the function execution node selection control unit 3 which has received the function execution command data 307 (step 20 in FIG. 3).
2) is a node address group name which is a group name of a function executing node having a function to be executed which is set in the function executing instruction data 307, and a node address group name 311 which is stored in the node address selection information database 32. Of the node groups with the same (Fig. 4), the node with the lowest load (the number of executions is the smallest) (Op
1-A to Op1-D, etc.) to determine the function execution node to be transmitted (step 203 in FIG. 3).

Subsequently, the node address name 312 of the selected function execution node is set in the destination address information part of the function execution command data 337 and transmitted (step 20).
4). The image at this time is shown in FIG. After transmitting the function execution command data, the data of the number of executions 343 of the corresponding record 354 (FIG. 5) in the node address selection information database 32 is updated (in the example, 1 is added) (step 205).

On the other hand, the operation system which has received the function execution command data 337 (step 206) executes the relevant function based on the data set in the function execution command data 337 (step 207). The operation system is Op1-C in the image of FIG.
Has become. When the execution of the function is completed, the function execution result data 367 is transmitted to the process control system 1 (step 208). The image at this time is shown in FIG.

The process control system 1 that has received the function execution result data (step 209) sends the corresponding record 38 in the node address selection information database 32.
4 (FIG. 6) update the data of the number of executions 373 (1 in the example)
Subtraction) (step 210). Then, the function execution result data is transmitted to the process execution control unit 2 (step 21
1), the process execution control unit 2 receives the function execution result data, and then the function to be executed next is selected (step 212).

Through the above procedure, a series of processing from the execution of the function execution instruction to the arrival of the end notification is completed.

7 to 10 are diagrams for explaining that the function executing node selection determining method according to the present invention is effective in reducing the overall processing time. First, FIG. 7 shows that there are a plurality of function execution nodes when the function execution node selection determination method according to the present invention is implemented. And 44 in FIG.
1, the function execution nodes (401, 402, 4
There are three cases in which the processing can be completed in a shorter time than the case where the function is executed sequentially by one function execution node (421 in FIG. 9).

In 411 of FIG. 8, a function execution node processing time 412 indicates a time zone in which processing is occupied by the function execution node, and operation target access times 413, 414 indicate time periods in which processing is occupied by the operation target. . Here, as shown by 421 in FIG. 9, when the number of function execution nodes is one, the function execution node processing times 422, 423, 424
Cannot overlap because there is only one function execution node.

On the other hand, as shown by 441 in FIG. 10, when there are three function execution nodes, the function execution nodes that process the functions perform processing independently, so that the function execution node processing times 442, 443, and 444 are There is no problem even if they overlap. As a result, in the case where there are three function execution nodes,
The overall processing efficiency is improved.

FIG. 11 is an explanatory diagram for explaining that the function executing node selection determining method according to the present invention is effective in smoothing the load of function processing. Reference numeral 511 in FIG. 11 is an image when the function execution command data is distributed to the function execution nodes in the conventional fixed manner. That is, with the conventional method, even if the function execution command data 504 is deviated to a specific function execution node, the transmission destination of the function execution command data 504 cannot be changed.

On the other hand, reference numeral 521 in FIG. 11 is an image of distribution of function execution instruction data when the present invention is applied. According to the method of the present invention, the function execution command data 504 is distributed according to the number of transmissions of the function execution command data managed by the process control system 1.
The processing load of all function execution nodes is smoothed, and as a result, the processing performance is improved.

In this embodiment, the data is managed by the database, but the entity for managing the data in the present invention is not limited to the database management system.

[0041]

As described above, according to the present invention, when a plurality of function execution nodes for executing the same function are arranged, the processing is executed in the shortest time when the commands for the processing for executing the same function are concentrated. By doing so, it is possible to prevent the relevant function from becoming a bottleneck for the entire business.

Further, since the state of the entire function executing node that executes the same function is managed, it becomes possible to evenly distribute the processing load as a whole, and as a result, the processing efficiency is improved.
