Device and Method for Controlling Management and Maintenance of Hardware In Exchanger System

The present invention relates to a hardware management and maintenance apparatus and method in an exchange system, and in particular, hardware management and maintenance such as hardware replacement due to a change and failure, such as addition and deletion of hardware, which may occur during system operation, and a memory database. It relates to a hardware management and maintenance method in the exchange system to be performed based on.

In general, in a mobile switching system, a block for performing a hardware management function exists, and the block holds information for hardware management.

In this case, the hardware management information includes a hardware identifier, a hardware name, a module identifier to which the hardware belongs, a hardware slot number, a hardware state, and the like.

In addition, if changes such as hardware addition, deletion, replacement, etc. occur during the operation of the system, the hardware management block must apply the changes newly.

Hardware management is performed in real time using a command or system library provided by the operating system. Whenever a hardware state change occurs while performing a hardware function, the hardware management block uses a message queue. Send the fact to the system operator terminal.

The hardware maintenance function is performed by a corresponding system operator terminal. The hardware maintenance function includes hardware state management, hardware addition, hardware deletion, and the like.

Then, the configuration of the apparatus for hardware management and maintenance in the conventional mobile switching system is composed of a system main unit 10, a system operator terminal 20, as shown in Figure 1, the system main control unit 10 It includes a hardware 11 to be managed, a system operating system 12, a hardware management block 13, and a queue 14, and a system main controller 10 in the system operator terminal 20. The system operator hardware management block 21, which is a block for processing a state related function of the hardware, and a queue 22.

The state of the managed hardware 11 is checked in real time through a command or a system library provided by the system operating system 12.

The system operating system 12 is an interface between the managed hardware 11 and the hardware management block 13. The system operating system 12 provides a command or a system library to obtain information on the status of the managed hardware 11 and failure information generated during system operation. Stored in the hardware management block 13.

The hardware management block 13 receives a message from the system operator hardware management block 21 through the queue 14 requesting the status of the hardware to be managed 11 in the current system main controller 10, and thereby the system operating system. The system operator hardware management block 21 checks the state of the hardware using the 12 and stores the result as a file, and then, in real time, the processing result message for the state request message through the queue 22. To send. In addition, the failure information of the management target hardware 11 obtained from the system operating system 12 is received, and the failure information of the hardware is transmitted to the system operator hardware management block 21 through the queue 22.

The system operator hardware management block 21 is a block for processing hardware state related functions in the system main controller 10 in the system operator terminal 20. The system operator hardware management block 21 generates a message requesting hardware state information to generate the queue 14. To the hardware management block 13 through.

The queue 14 receives hardware management information and changed hardware information required from the system operator hardware management block 21, which is a block for processing hardware state related functions in the system main controller 10, and receives the changed hardware information to the hardware management block 13. to provide.

The queue 22 receives the status check result of the management target hardware 11 transmitted from the hardware management block 13 and failure information generated during system operation, and provides the received information to the system operator hardware management block 21.

The operation of the configuration as described above is as follows.

First, referring to the hardware management operation, the hardware management block 13 registers state information of hardware newly installed or changed in the system operating system 12 to acquire the state and failure information of the hardware during system operation.

As described above, if the hardware management block 13 detects a status request message from the system operator hardware management block 21 while the system is operating while the state information of the hardware is registered in the operating system 12, the management target hardware ( After checking the state of the 11) and storing it as a file using a command or system library provided by the system operating system 12, the response message for the corresponding state through the queue 22 to the system of the system operator terminal 20 Send to operator hardware management block 21.

In addition, when a hardware failure occurs during system operation, the failure information is recognized and stored in the hardware management block 13 through the operating system, and the hardware failure information stored in the hardware management block 13 is stored in the system operator through the queue 22. Send to hardware management block 21.

In addition, referring to the hardware maintenance operation, the operation of replacing, deleting, or adding a hardware device during system operation is performed by the operator, and the hardware management block 13 is a system operator hardware management block in the system operator terminal 20. After compiling by applying change operation information such as hardware replacement, deletion, and addition provided in (21), the current state of the management target hardware 11 is monitored in real time and transmitted to the system operator terminal 20.

As such, in the conventional switching system, the hardware management and maintenance method includes changing the hardware management check method, adding new hardware, deleting new hardware, or replacing existing hardware. It must be applied newly.

In addition, in order to manage the status of all hardware of the system in the system operator terminal, the hardware management block needs to send a status request message and a response message. Therefore, the use of the message queue increases the load on the system and requires the use of system resources. There was a problem.

In order to solve the problems described above, the present invention is to build a hardware management and maintenance information in a real-time memory database in the exchange system to perform a hardware management and maintenance function based on the real-time memory database, It improves the flexibility of system operation by minimizing the cost and effort caused by changes in hardware addition, deletion, and replacement that can occur during system operation, and also uses the message queue for the interface between the hardware management block and the operator terminal. Its purpose is to save system resources and reduce the load on the system.
