Description

Alarm processing device and method in base station controller {APPARATUS AND METHOD FOR PROCESSING ALARM IN BSC}

The present invention relates to an apparatus and method for processing an alarm in a base station controller, and more particularly, to an apparatus and method for processing an alarm of a control unit of a base station controller.

In general, a mobile communication system includes a base station for performing data communication using a wireless channel with a mobile communication terminal in a predetermined unit of area in order to provide activity of the mobile communication terminal. In addition, a plurality of base stations are wired to the base station controller to perform a call connection for providing to the mobile communication terminal or receive state information of the base station and control information required by the base station. The base station controller transfers the incoming call to the base station or receives the call information of the mobile communication terminal from the base station and delivers it to the mobile communication switching system. Through this process, the base station controller controls the base station. Next, an internal block configuration of the base station controller will be described with reference to FIG. 1.

1 is an internal block diagram divided by functions of a base station controller. Each board and functional block of the base station controller is redundant for fault handling. However, this is not specified or illustrated in FIG. 1, and in the following description, no special explanation will be made except when a description of the duplication is required.

The switch 11 performs a switching operation for connection between each multiplexer or manager connection of the base station controller. Through this switching operation, the call request signal received from the base station can be delivered to the mobile communication switching system. In addition, it transmits various information received from the base station and the status information of the base station controller to the host system. The first multiplexer 12 performs a connection between the switch 11 and the plurality of TCLA boards, and the data transmitted to each board is multiplexed and transmitted when the connection is made. The plurality of TCLA boards are connected to a mobile communication system as a board for processing several calls. Accordingly, the number of TCLA boards varies according to the degree of an acceptable call, and the number of the first multiplexer 12 also varies accordingly. The second multiplexer 13 is connected to a plurality of AETA boards, and the AETA boards are connected to respective base stations to perform call processing or failure and transmission and reception of various data. In addition, the second multiplexer 13 multiplexes and transmits a signal to be transmitted and received. The second multiplexer 13 is also configured differently according to the number of base stations connected to the lower part and the number connected to the AETA board.

The third multiplexer 14 is configured to connect between the switch 11 and the controller 15, and multiplexes a signal received from the switch 11 and transmits the signal to the controller 15 or from the controller 15. The signal output to the switch 11 is multiplexed and transmitted. The fourth multiplexer 16 is connected to a plurality of BHPA boards, and the BHPA boards are boards for controlling a predetermined operation, respectively. The fourth multiplexer 16 also multiplexes and transmits signals transmitted and received between the boards and the switch like the first and second multiplexers 12 and 13. The manager connection unit 17 is wired to the system for managing the base station controllers, and receives information such as an alarm from each board in the base station controller and transmits the information to the management system. In this case, generally, the connection between the management system and the manager connection unit 17 is connected to the STM-1 class using an optical line. Since this is a design matter, it may be changed to STM-4 to STM16 or the like, or may be connected using another method such as a LAN.

In addition, each of the multiplexers 12, 13, 14, and 16 detects an alarm of boards connected to the lower side and informs the controller 15 of the alarm. In other words, there are tasks for performing this. Therefore, each of the tasks checks the status of each board below, and transfers it to the controller 15 when a failure or alarm occurs in the board. This will be described below with reference to the configuration of Figure 1 for example.

When a failure occurs in a predetermined board among the TCLA boards, the first multiplexer 12 detects this and transfers information of the TCLA board in which the alarm occurs to the third multiplexer 14 through a switch 11. . Then, the third multiplexer 14 receives the received signal and multiplexes the received signal to the controller 15. Then, the controller 15 converts the alarm occurrence information into a form for notifying the management system, and then transfers the generated alarm information to the third multiplexer 14. Then, the third multiplexer 14 transfers the data received from the controller 15 to the manager connection unit 17 through the switch 11. Accordingly, the manager connection 17 transfers it to the management system 17.

Through the above process, the failure state of the base station controller can be confirmed in the management system. However, if a failure occurs in the fraud control unit 15 may occur. In other words, when a failure occurs in the control unit 15, not only the failure information can be received from the lower level and transmitted to the management system, but also a problem in which the failure of the control unit 15 cannot be notified to the management system occurs. In more detail, the third multiplexer 14 connected to the controller 15 may detect a failure of the controller 15. However, when a failure of the controller 15 is detected, the controller 15 is notified again. As a result, the controller 15 may not receive and process the failure because it is in a failure state. This may be the case where both boards have failed even when the controller 15 is redundant, or a failure may occur in the mounted board in a state where one board is dismounted. Therefore, even if the board is doubled, if both boards fail or if another board that is doubled in the state where one board is detached fails, this is not known to the management system.

Accordingly, an object of the present invention is to provide an apparatus and method for identifying a failure occurring in a control unit of a base station controller in a management system.

Another object of the present invention is to provide an apparatus and method for more accurately identifying a failure state of a base station controller.

An apparatus according to the present invention for achieving the above objects is an apparatus for processing an alarm in a base station controller of a mobile communication system, a plurality of base station connection boards capable of transmitting and receiving data with the boards connected to the base station, and A plurality of mobile communication system connection boards connected to a communication exchange system capable of transmitting and receiving data, a control unit for controlling overall operations of the base station controller, and an interface for transmitting an alarm state of the base station controller to a management system. Provides a manager connection unit, the control unit, the base station connection boards and the mobile communication system connection boards are multiplexed the signals transmitted and received, and checks the alarm of each board and transmits to the control unit, when connected to the control unit The alarm of the control unit to the management system when an alarm is detected And multiplexers and a switch forming a path for data transmission and reception between the multiplexers and the manager connection unit.

In addition, the multiplexer may be configured to directly transfer an alarm signal from another multiplexer to the management system when an alarm occurs in the controller.

A method according to the present invention for achieving the above objects is a method for processing an alarm in the alarm processing board provided in the base station controller of the mobile communication system, the controller by reading the type information of the other boards connected to the alarm processing board Checking whether the controller is connected to the controller, checking the alarm information of the boards connected at predetermined intervals when the controller is connected to the control unit, checking whether the generated alarm is a control unit alarm, and generating the alarm. In case of the control unit alarm, a process of transmitting the alarm information of the control unit directly to the management system of the base station controller.

The method may further include storing the generated alarm information in an alarm management table when detecting the occurrence of the alarm. Further, when the generated alarm is not an alarm of the controller, transferring the generated alarm information to the controller. When the alarm signal is received from another alarm detection board after the alarm of the controller occurs, it may further include a process of directly transmitting it to the management system.

1 is a block diagram illustrating the interior of a base station controller to which the prior art and the present invention are applied, divided by functional blocks;

2 is a control flowchart when an alarm is processed in a multiplexer according to an exemplary embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an internal block diagram divided by functions of a base station controller to which the present invention is applied.

Most of the blocks of FIG. 1 perform the same operation as in the prior art description. Therefore, the detailed description will not be made for the part performing the same operation. However, according to the present invention, the operation of the multiplexer may be divided into a case where the operation of the multiplexer is connected to a case where the operation of the multiplexer is not. In detail, when the multiplexer connected to the controller 15 among the multiplexers, that is, the third multiplexer 14, detects a failure of the controller 15 when it is connected to the controller 15 according to the present invention. This informs the alarm status of the controller 15 to the manager connection 17 directly via the switch 11. Accordingly, the manager connection unit 17 notifies the management system of the failure state of the control unit 15.

2 is a control flowchart when an alarm is processed in a multiplexer according to an exemplary embodiment of the present invention. Hereinafter, the operation of the multiplexer according to the present invention will be described in detail with reference to FIGS. 1 to 2. In the following description, since the multiplexer may be any multiplexer among the multiplexers shown in FIG. 1, the multiplexer will be described without using a special reference numeral.

When the multiplexer is connected to the base station controller and is mounted, the process proceeds to step 100 to read type information of all boards connected to the multiplexer, that is, loaded boards. Type information is to read information about the types of boards mounted in the base station controller from each board. The multiplexer reads the information of the boards and proceeds to step 102 to check whether the controller of the currently connected boards is connected. If the control result is connected to the control unit proceeds to step 106, otherwise proceeds to step 104. When the multiplexer proceeds to step 104, the operation as described in the related art is performed.

In contrast, when the control unit is connected to the multiplexer and proceeds to step 106, the task of processing the alarm of the multiplexer checks the alarms of the boards connected at predetermined intervals. The inspection of the alarm may directly check the alarm status of each board through the transmission and reception of a signal, or alternatively, the information stored in the register may be read and used using a register that records the alarm information. In the present invention, any method can be used. The multiplexer reads the alarm information in predetermined cycles and proceeds to step 108 to check whether there is a board in which an alarm has occurred. If there is a board with the alarm result, the process proceeds to step 110; otherwise, the process proceeds to step 106.

In step 110, the multiplexer records information on an alarm generated in an alarm management table provided in the multiplexer. In operation 112, it is checked whether the generated alarm is an alarm of the controller. In the case of the alarm of the test result controller, the process proceeds to step 114; When the alarm occurs in the control unit and proceeds to step 114, the alarm information is transmitted to the management system. Proceed to step 106. The transmission of such alarm information will be described with reference to FIG. 2.

When the alarm of the controller 15 is detected, the third multiplexer 14 generates a destination address in order to deliver the generated alarm information to the management system, and transmits the destination address to the manager connection unit 17 through the switch 11. The manager connection 17 then transfers this to the management system. Usually, since the IPC communication is performed between the multiplexer connected to the inside of the base station controller and the manager connection, the alarm information is converted into IPC data format and transmitted.

On the contrary, if the alarm is not the controller, that is, the alarm of another board, the controller proceeds to step 116 to notify the controller of the generated alarm of the other board to the controller 116. Then go back to step 106.

In addition, when an alarm occurs in the controller, the multiplexer connected to the controller may be configured to directly transfer the alarm information of the boards connected to the lower part from other multiplexer boards to the management system. Unlike this, the alarm information received from the other boards may be configured to be transferred to the controller in the same manner as in the prior art, or may be configured to ignore the received information. This is a system design that needs to consider the load of the system and the load of the multiplexer.

As described above, it is possible to more accurately grasp the processing of the alarm generated in the base station controller, and there is an advantage that the maintenance is convenient by accurately grasping the state of the base station controller.
