If the management request for the management object is the first management object creation request, the content of the management object to be created is converted to BER format, and then the management object is stored on disk using the DN value as a key through the database. In case of deletion request, the DN value of the management object to be deleted is converted to BER format, and if there is a management object to be deleted on disk using the DN value as a key through the database, the management object is deleted from the disk. If so, convert the DN value of the managed object to get to BER format, and then Through the DN value as a key, if there is a management object to get on the disk, the contents of the management object are read. Finally, if the management object value set request is made, the contents of the management object to be set are converted to BER format, and then the data is read. It is characterized by changing the management object contents of the disk through the base.In this way, as the TMN agent stores and manages the managed objects by using the disk, it stores and manages many managed objects efficiently without additional main memory. There is an effect that can be done.

Description

Managed object management method in the TMN agent

The present invention relates to all or a Managed Object (MO) in a TMN Agent serving as an interface between an exchange and a Telecommunication Management Network (hereinafter, referred to as 'TMN') Manager. The present invention relates to a method of managing a managed object in a TMN agent that enables a quick search for a managed object by storing a part of the file in a disk and managing the file.

In general, TMN is a standardized network recommended by ITU-T (International Telecommunication Union) M.3010, which centralizes mobile operators by implementing TMN agents in mobile communication exchanges. Enable efficient and efficient mobile network management.

The TMN agent 20 serves as an interface by using a workstation commercialized between the exchanger 10 and the TMN manager 30 as shown in FIG. 1.

The exchanger 10 and the TMN agent 20 communicate IPC (Inter Process Communication), which is a communication method between the internal processes of the exchanger 10, through RS-422, and between the TMN agent 20 and the TMN manager 30. Communicates with the Common Management Information Protocol (CMIP) via the Q3 interface recommended in ITU-T X.711, Q.811, and Q.812.

Meanwhile, in the conventional TMN agent 20, the management object to be managed is stored in the main memory of the TMN agent 20 and managed.

However, such a management object management method can be used without any problem when the number of management objects to be managed is not large, but it is difficult to use the management object due to the following problems.

First, all managed objects cannot be stored because of the limitation of main memory.

At this time, there may be a way to solve by installing additional main memory, but the price of the main memory is expensive, even if additional installation may not be able to store all the management objects.

Second, the initialization process of the TMN agent 20 cannot be performed because the generation speed of the management object is slow when the TMN agent 20 is initialized.

In this case, the size of the entire memory can be increased by using the virtual memory. However, in this case, due to the frequent swapping between the virtual memory and the main memory, the management object generation speed is significantly reduced, and the TMN agent initialization process takes a considerable time.

The present invention has been made to solve the above problems, the object of the TMN agent is to store the whole or part of the management object in a file on the disk to manage the TMN agent to enable a quick search for the management object To provide a way to manage managed objects in.

In the management object management method in the TMN agent of the present invention to achieve this object, if the management request for the management object input from the TMN manager is the first management object creation request, the content of the management object to be created is in BER format. After converting, the managed object is stored on disk with DN value as a key through the database.In case of request to delete the managed object, the DN value of the managed object to be deleted is converted to BER format, and then the DN value is converted to key using the database. If there is a management object to be deleted on the disk, delete the management object from the disk.If the third management object value request is required, convert the DN value of the management object to get to BER format, and then use the database as a key. If there is a management object to get on disk, the contents of the management object are read. If the value set requirements, characterized in that to change the managed object information of the disk through one converts the contents of the management object to set the BER format, then the database.

Hereinafter, a management object management method in a TMN agent according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 shows an example of a management object having a tree structure, in which a management object managed by a TMN agent has a tree structure, and each management object has a Distinguished Name (DN) that uniquely identifies itself. have.

The TMN agent according to the present invention can store and manage all or a part of the managed objects managed by itself, for example, all managed objects belonging to the managed object A and its subtrees as shown in FIG. That is, all managed objects from A to Q can be stored and managed on disk, and managed objects E, F, N, O belonging to managed object B and its subtrees, or managed objects belonging to managed object D and its subtrees. Like objects K, L, and M, some managed objects can be stored and managed on disk.

The disk used by the TMN agent for managing the management object of the present invention is much larger than the main memory, so it can store a large number of management objects, and even if a large number of management objects are created during initialization of the TMN agent, the creation speed does not slow down. Can be done quickly.

In the management object management method of the present invention, a database (ndbm) provided by Unix, which is a TMN agent operating system, is used for efficient and fast disk storage / retrieval of the management object.

In addition, TMN agents store managed objects on disk in the Basic Encoding Rules (BER) format recommended by ITU-T X.209.

Next, the management object management method in the TMN agent according to the present invention will be described in detail.

3 is a flowchart illustrating a processing operation of a TMN agent when receiving a management object creation request from a TMN manager, and FIG. 4 is a flowchart illustrating a processing operation of a TMN agent when receiving a management object deletion request from a TMN manager. 5 is a flowchart illustrating a processing operation of a TMN agent when a management object Get request is received from a TMN manager, and FIG. 6 is a processing of a TMN agent when a management object Set request is received from a TMN manager. This is a flow chart.

First, the management object creation process in the TMN agent is described.

When the TMN agent receives the management object generation request from the TMN manager (S1), it is determined whether the management object is a management object stored in the disk or a management object stored in the memory (S2).

If the management object is stored on the disk in the step (S2), the DN value of the management object is converted into the BER format recommended in ITU-T X.209 (S3), and then the database provided by Unix is used as the DN value as a key. Search whether there is a corresponding management object on the disk (S4).

If there is no corresponding management object on the search result disk (S5), the contents of the management object are also converted to BER format (S6), and then the management object is stored on the disk with DN as a key through the database and the result is returned to the TMN manager. Send (S7).

If the management object stored in the memory in the step (S2) and whether there is a management object in the memory (S8), if there is no management object in the memory generates a management object in the memory and transmits the result to the TMN manager (S9).

If there is a corresponding management object in the disk or the memory in the steps S5 and S8, an error message is transmitted to the TMN manager (S10).

Second, the process of deleting managed objects in TMN agent is explained.

When the TMN agent receives the management object deletion request from the TMN manager (S11), it is determined whether the management object is a management object stored in the disk or a management object stored in the memory (S12).

If the management object is stored on the disk in step S12, the DN value of the management object is converted into the BER format (S13), and then, whether the management object exists on the disk through the database using the DN value as a key (S14). ).

If there is a corresponding management object on the search result disk (S15), the management object is deleted from the disk using a database and the result is transmitted to the TMN manager (S16).

In step S12, if the management object is stored in the memory, the management object is searched for in the memory (S17). If the management object exists in the memory, the management object is deleted from the memory and the result is transmitted to the TMN manager. (S18).

If there is no corresponding management object in the disk or memory in the above steps S15 and S17, an error message is transmitted to the TMN manager (S19).

Third, the management object get process in the TMN agent is described.

When the TMN agent receives the management object value request from the TMN manager (S21), it is determined whether the management object is a management object stored in a disk or a management object stored in a memory (S22).

If the management object is stored on the disk in step S22, the DN value of the management object is converted into the BER format (S23), and then, whether the corresponding management object exists on the disk through the database using the DN value as a key (S24). ).

If there is a corresponding management object in the search result disk (S25), the contents of the management object stored in the disk are read using a database and the result is transmitted to the TMN manager (S26).

In step S22, if the management object is stored in the memory, the management object is searched for in the memory (S27). If the management object is in the memory, the contents of the management object stored in the memory are read to the TMN manager. Transmit (S28).

If there is no corresponding management object in the disk or memory in the steps S25 and S27, an error message is transmitted to the TMN manager (S29).

Finally, the process of setting up managed objects in the TMN agent is described.

When the TMN agent receives the management object value set request from the TMN manager (S31), it is determined whether the management object is a management object stored in the disk or a management object stored in the memory (S32).

If the management object is stored on the disk in step S32, the DN value of the management object is converted into the BER format (S33), and then, whether the management object exists on the disk through the database using the DN value as a key (S34). ).

If there is a corresponding management object in the search result disk (S35), the content of the management object to be changed is converted into BER format (S36), and then the content of the management object stored in the disk is changed using a database and TMN The result is transmitted to the manager (S37).

In step S32, if the management object is stored in the memory, the management object is searched for in the memory (S38). If the management object exists in the memory, the contents of the management object stored in the memory are changed and the TMN manager is sent to the management object. The result is transmitted (S39).

If there is no corresponding management object in the disk or memory in the steps S35 and S38, an error message is transmitted to the TMN manager (S40).

As described above, according to the present invention, as the management object storage and management in the TMN agent is performed using a disk, the management object can be efficiently stored and managed without adding a main memory. There is an effect that it is possible to prevent the increase in the unit cost of the TMN agent.
