Description

Fault management method of digital frequency common communication system

The present invention relates to fault management in a digital trunked radio system (hereinafter, abbreviated to D-TRS) system. In particular, a personal message capable of graphic processing of a fault message generated during operation of the D-TRS system in a window environment is possible. The present invention relates to a fault management method of a digital frequency common communication system that allows a user to manage the computer (PC) for convenience and to manage faults remotely through a modem.

In general, frequency common communication (TRS) is a system in which a plurality of channels are shared by a plurality of users so that the user automatically selects and uses an empty channel among the plurality of channels. Therefore, the use of frequency is high, the call quality is improved, data communication and fax (FAX) communication is possible, and the frequency uses 800 [Mhz] band.

This TRS system can give individual call to mobile station (mobile phone) to make individual call, and can make all call with the whole group at command center. The communication function and simultaneous notification service in case of emergency can be used for security, transportation, construction and port fields.

The characteristic of D-TRS system in TRS system that performs this function is that frequency hopping (FH) per channel is used, so the frequency hopping rate is lower than 200 [hops / sec] and is generally 40 at 10 frequencies. It provides a voice channel of the channel and vocodes a voice of 4.8 [Kbps] using a voice encoder.

The configuration of the switching center controller in the D-TRS system performing this function is as shown in FIG.

As shown here, the central control unit 1 for controlling the operation of the frequency common communication system through the Ethernet (Ethernet) network; A database server (2) for providing a database of a frequency common communication system through the Ethernet network; An operation control unit (3) for controlling an operation of the frequency common communication system through the Ethernet network; A data control unit (4) for controlling data operated in a frequency common communication system through the Ethernet network; A base station controller (5) for controlling a base station of a frequency common communication system through the Ethernet network; A system performance monitoring unit (6) for monitoring the performance of the frequency common communication system and performing statistical processing through the Ethernet network; It consists of a local controller (7) for changing the parameters of the operating system through the Ethernet network.

The switching center controller of the conventional frequency common communication system configured as described above performs initialization of each control unit (1 to 5) by using a monitor and a keyboard installed for each of the five control units (1 to 5) connected through an Ethernet network, and performs frequency sharing. The communication system was activated.

On the other hand, the switching center controller as described above manages the failure details that occur during system operation through the local controller.

However, the function provided by the local controller was only a screen output of the fault message, and it did not provide a function for later fault history management (file saving and printing, statistical function, etc.). Therefore, the operator had to record the contents printed on the screen by hand, and there was an inconvenience to check each occurrence of the failure, which lowered the work efficiency.

In addition, since the local controller performs additional functions (configuration management, system parameter setting, initialization result output, etc.) in addition to failure history management, independence of the failure management system is required for the rapid stabilization of the system in the event of a failure.

Accordingly, the present invention has been proposed to solve various problems occurring in the conventional switching center controller as described above.

An object of the present invention is to manage the error message generated during the operation of the D-TRS system from a personal computer (PC) capable of graphic processing in a Windows environment, to facilitate the operator and to manage the problem remotely through a modem. To provide a failure management method of a digital frequency common communication system.

7: Local controller 8: Personal computer

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention according to the technical spirit as described above in detail.

2 is a configuration diagram of an exchange station controller of a digital frequency common communication system to which a personal computer is applied in the present invention.

Here, reference numeral 1 denotes a central control unit, 2 a database server, 3 an operation control unit, 4 a data control unit, 5 a base station control unit, 6 a system performance monitoring unit, and 7 a local controller. It is the same as that of the conventional switching center controller.

The present invention is implemented by further including a personal computer (8), which is a failure management system for managing a failure message generated in the switching center controller, in the configuration of the conventional switching center controller configured as described above.

The switching center controller according to the present invention having such a configuration stores and stores in a database a failure related message generated during the operation of the switching center controller in the database server 2.

In this state, in order to manage this through the personal computer 8, the personal computer 8 and the database server 2 should be connected in the concept of a client and a server as shown in FIG.

For this purpose, the database server 2 in the switching center controller assigns one of the IP addresses already defined for the D-TRS system for the personal computer 8 for TCP / IP communication, and the personal computer 8 has a LAN cable. To the Ethernet Switching Hub (HUB).

Here, the database server 2 performs a database (including configuration information, failure information, system parameters, subscriber information, etc.) of the SYBASE SQL server system 11 and the application of the D-TRS system itself. Consists of database operations (DBM) blocks.

The personal computer 8, which is a failure management system, maintains a client-server relationship with the database server 2 having the above functions, and provides functions such as output, storage, printing, and statistics of failure information.

That is, in order to perform a desired function in the personal computer 8, a connection for network TCP / IP communication with the database server 2 should be made. In other words, an IP address (for example, 172.20.44.100) of the personal computer 8 should be assigned, and the database server 2 installs a SYBASE client program to the personal computer 8 to provide the corresponding interface. Do it.

Here, the SYBASE client program includes SQL edit and SYBASE ping, and the database server name (Geonet46) to connect using SQL edit, port number and IP address (M_DBS IP address) for TCP / IP communication. : 172.16.0.106), Net-Library Driver, etc., and check the connection (communication possibility) with the selected server using the SYBASE ping. At this time, if the ping is successful, the connection with the server is successful.

After the connection with the server is completed, the personal computer 8 operates the failure management system using Power Builer 5.0.

The failure information table in the required database system is as follows.

db_current_indication, db_history_indication, enm_msg_type, enm_rack_msg_type.

The personal computer 8 receives the above-described failure history related table from the server and performs failure management as shown in FIG.

4 is a flowchart illustrating a failure management method according to the present invention.

As shown therein, a first step (ST1 to ST2) of selecting a fault message on a main window of a window in a state where a personal computer and a database server of a D-TRS system are connected for network TCP / IP communication; A second step (ST3 to ST5) of classifying a type and a grade of the received failure message after receiving the selected failure message from the database server; A third step (ST6) of statistically processing the failure message after classifying the type and grade of the failure message; A fourth step ST7 is performed to process the statistically processed fault message in the selected form according to the operator's selection of result processing.

In the problem management method, the operator first completes a login (processing procedures such as user confirmation, registration management, and exchange of network information between the user and the system), and then displays a desired error message by viewing the main menu displayed on the screen. (ST1 to ST2).

Here, the failure message displayed in the main menu includes a history failure message which is a previously generated failure message and a current failure message which is a currently generated failure message.

If the user selects a history failure message, which is a previous failure message, the database server 2 transmits the previously stored history failure message to the personal computer 8 (ST3).

The personal computer 8 which received this classifies the type and grade of the received history failure message (ST5).

That is, the failure message is first classified into a status and an event type, and the status message is classified into a second type by failure and recovery, and then the type is classified. Each fault message is classified into high and low signals.

Next, the fault message that classifies the type and the grade is statistically processed by type (ST6).

Then, the result of the fault is processed according to the operator's selection of result processing of the statistically processed fault message (ST7).

That is, when the operator selects the save function, the output failure message is saved as a file. The file format saved at this time is Excel & Text and can be selected when saving.

In addition, when the operator selects the output, the failure message generated during operation of the D-TRS system is classified into contents such as occurrence location, occurrence grade, status, occurrence time, and the like and displayed on the screen. Here, the fault messages displayed on the screen can be sorted by the time in which they occurred.

In addition, when the operator selects printing, the printed error message is transmitted to the printer to print.

In addition, even when the operator selects the currently generated failure message in the failure message selection step ST2, the database server 2 delivers the currently generated failure message to the personal computer 8 (ST3).

Hereinafter, the process of classifying and classifying the current fault message, the process of statistics of the fault message, the process of storing and printing the fault message, and the process of storing and printing the fault message are the same as the process of handling the history fault message described above. Detailed description will be omitted.

The present invention described above has described a method for managing a D-TRS failure in a personal computer using a LAN cable, but the present invention is not limited thereto, and remote failure management can be performed through a modem.

That is, the modem is installed in the personal computer, and the corresponding failure message is interfaced to the remote terminal through the modem. The receiving remote terminal processes the received failure message in the same manner as the above-described failure message management method. The fault management of the D-TRS system is possible.

As described above, the present invention can be easily operated by anyone without additional learning, since it is possible to perform a problem management task on a graphic screen using a personal computer and a problem management program. There is an advantage to reduce effort and effort.

In addition, the modem has the advantage of remotely managing each local operator's failure history from the central center, which has the advantage that can support each local operator's stabilization of D-TRS system faster and more efficiently.
