Description

Method for Analyzing Error Message in Mobile Telecommunication System {Method for Analyzing of Error Message in Mobile Telecommunication}

The present invention relates to a method for analyzing various failure messages occurring in a mobile communication system. More specifically, a mobile communication system that receives various failure messages generated by various devices installed on a mobile communication system in real time, analyzes the failure messages by time zone or location, and checks the equipment in which the failure occurs at a glance, and takes quick action. It relates to a method of analyzing fault messages occurring in.

Recently, with the rapid development of electronic and communication technology, mobile communication systems and services through wireless communication terminals are also evolved into various forms such as wireless access methods. The mobile communication system has time division multiple access (TDMA: TDMA), frequency division multiple access (FDMA) and code division according to a wireless access method. It is classified as multiple access (CDMA: Code Division Mutiple Access, hereinafter referred to as 'CDMA').

In particular, the CDMA method is a technology in which the development of technology has been made dramatically since the commercial service is performed in Korea for the first time in the world. Such a mobile communication system includes a mobile communication terminal, a base station (BS) and a mobile switching center (MSC). In addition, the wireless base station includes a base station controller (BSC), a base transceiver station (BTS), a repeater (Cell Enhancer), and the mobile switching center includes a home location register (HLR) and a visitor. It consists of a Visitor Location Register (VLR).

As various types of equipment are installed on the mobile communication system, a large amount of obstacles are constantly occurring in the equipment while the system is being operated. The failure of such a mobile communication system is very diverse, and the amount of failure messages generated by each device is also numerous. Therefore, a message monitoring device capable of monitoring various fault messages generated from equipment installed in the mobile communication system is installed on the mobile communication system.

However, currently operating fault message monitoring device provides only a function such as simply displaying randomly all fault messages generated by various equipment installed in a wireless base station or switching center, or generating an audible alarm when a specific fault message occurs. Doing.

1 is an exemplary screen illustrating a failure message provided by a current failure message monitoring apparatus.

The fault message monitoring apparatus collects fault messages generated from various devices installed on the mobile communication system and extracts constant information such as occurrence time, fault code, location, fault detail information, and the like as shown in the example screen of FIG. Display.

As can be seen from Figure 1, the failure message monitoring device is assigned a specific failure code (Code) for each type of failure, and sets and classifies and manages the importance of failure for each code. For example, fault messages such as some call processing failures due to a failure of a specific board of the base station equipment are of low importance, while all call processing failures within the wireless base station due to system down of the wireless base station may be reduced. The same fault message has a very high priority.

Therefore, the failure message monitoring device additionally provides a function that enables the administrator to immediately check the occurrence of a failure by sending an alarm sound, etc., from the administrator's computer when a critical failure message that is fatal to the mobile communication system occurs. have.

However, the alarm sound transmission function in case of an important fault message provided by the fault message monitoring device merely informs the fact of the fault and the location of the fault equipment, and when the fault occurred, and at what frequency (for example, how many times per hour). The disadvantage is that it does not provide information about what happens.

Therefore, the manager tends to spend time in order to determine whether a failure occurs temporarily when the failure message occurs, whether the failure has occurred continuously, when the failure occurred, or how frequently the failure occurs. As a result, even when a major failure occurs in the mobile communication system, a quick action is not taken, which may cause a very bad adverse effect on the communication system.

Meanwhile, referring to the example screen of FIG. 1, it can be seen that a failure message ('F9201' or 'F4100') having a low importance is less frequently affected than a failure message of high importance. Therefore, if left unattended equipment is left unattended, it will continue to adversely affect the communication quality will be a big factor to increase customer complaints.

However, as explained above, the current fault message monitoring device provides all fault messages in real time at random and provides little other functions, which makes it difficult for the administrator to immediately recognize the same fault message that is continuously occurring. have. That is, in the example screen of FIG. 1, even when a screen displaying duplicate fault codes such as 'F9201' is rapidly changed to the next screen, it is often difficult for an administrator to recognize the actual site. For example, if the administrator is not looking at the monitor screen of a computer with a keen attention, it becomes very difficult to recognize the failure message of the same equipment which is of low importance but continuously occurs.

In order to solve the above problems, the present invention receives various failure messages generated by various equipment installed on the mobile communication system in real time and analyzes the failure messages by time zone or location to identify the equipment in which the failure occurs at a glance and quickly. An object of the present invention is to propose a method for analyzing fault messages occurring in a mobile communication system.

To this end, the present invention, a wireless communication terminal for performing a call diagram, a mobile communication network processing the call diagram, a failure message monitoring device for collecting and storing a failure message generated in the mobile communication network and a monitoring computer are connected through a network A method of analyzing a fault message occurring in a mobile communication system, wherein the fault message generated by at least one device installed in the mobile communication network is transmitted to the fault message monitoring device in real time while the fault message is being processed. Storing the data in real time; setting a mode for classifying the fault message by operating a message analyzing module built in the monitoring computer; and displaying the fault message corresponding to the set condition in the fault message database. from And classifying and displaying the extracted fault message according to the extracted and configured mode.

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

2 is a block diagram schematically illustrating a system for monitoring a failure message in a mobile communication according to an exemplary embodiment of the present invention.

Failure message monitoring system according to an embodiment of the present invention is a failure message monitoring device 230 including a wireless communication terminal 200, wireless base station 210, mobile communication switching center 220, failure message database 232 and It comprises a monitoring computer 240.

The wireless communication terminal 200 is a terminal that performs a call attempt for moving and using a voice or packet data service through a mobile communication network, and includes a wireless transceiver, an antenna, and a control device.

The wireless base station 210 refers to a base station having a wireless transceiver connected wirelessly to the wireless communication terminal 200 and transmitting a call request generated from the wireless communication terminal 200 to the mobile communication switching center 220.

The mobile switching center 220 has a control function that allows the wireless base station 210 to operate efficiently. In addition, the mobile communication switching center 220 is connected to a public switched telephone network (PSTN) / public switched data network (PSDN) to provide voice communication and data communication to the wireless communication terminal 200. Function.

The failure message monitoring device 230 collects a failure message generated by various equipment installed in a plurality of wireless base stations 210 or mobile communication switching centers 220 constituting the mobile communication system and stores the failure message in the failure message database 232. That is, the failure message monitoring device 230 may include information on the time (year, month, day, hour, minute, second) in which a failure occurred, information on a failure code, location information on a device in which a failure occurs, among information included in collected failure messages. Extract detailed information and the like and store the fault message in the database 232.

The monitoring computer 240 is a manager computer for identifying and supervising a failure occurring in each device installed on the mobile communication system. The monitoring computer 240 is connected to the failure message monitoring device 230 through a network to provide a real-time error message database 232. You can check the fault message that is saved. Of course, the monitoring computer 240 is always connected to the failure message monitoring device 230 through the network.

In addition, the monitoring computer 240 is provided with a message analysis module 242 for classifying and displaying various failure messages stored in the failure message database 232. The message analysis module 242 is a predetermined program that analyzes a failure message stored in the failure message database 232 by a failure code, a location of occurrence, a time of occurrence, a date of occurrence, and the like. In addition, the message analysis module 242 transmits an alarm sound through a speaker of the monitoring computer 240 or displays an alarm message on a monitor screen when a failure message having a high importance is set in advance.

Meanwhile, the message analysis module 242 may be applicable to not only CDMA described in the embodiment of the present invention but also a TDMA and FDMA mobile communication system.

3 is an exemplary screen of analyzing a failure message using the message analysis module 242 according to an embodiment of the present invention.

Referring to FIG. 3, it can be seen that a failure message received from the failure message database 232 is analyzed by time zone. The search period is April 29, 2002, one day, and the search time is set from 07:00 to 23:00. In addition, the sorting of fault messages is arranged by fault codes, and only a specific fault code may be searched through a 'code search' item. Therefore, the administrator can check whether there is a failure message that is overlooked without knowing it by inputting the failure code set for the important failure.

In FIG. 3, the failure codes 'A1680', 'A1781', and 'A2900' may be found to have a low frequency of failures, about 1 to 10 times, as can be seen from the 'SUM' item in the middle of the screen. However, the failure codes 'F1110', 'F1111', 'F1112' and the like occurs about 1000 times, it can be seen that the frequency of failure is very high.

That is, it is possible to immediately follow up by identifying a failure message with a high importance that is not recognized among failure messages with a low occurrence frequency of failures. In addition, the failure message of low importance, which is a low frequency of occurrence of a failure, is often a phenomenon that occurs momentarily rather than a failure caused by a failure of the component itself.

However, even a failure message of low importance has a very bad effect on the communication quality when the occurrence frequency of the failure is more than 1,000 times as in the example screen. Therefore, the administrator can identify the location of the equipment with the failure through the failure message with a very high frequency in the example screen and take immediate action. For example, in the case of a failure message having a failure code of 'F1110' and '1007' occurrences, the location of the failed component is 'BSC05 / BTS09 / BSDC00 / SHELF00 / DCP00'.

Here, the user can select a device to check the occurrence of the failure message through the 'system' item. That is, the equipment constituting the mobile switching center or the equipment constituting the radio base station can be selected. Since the 'system' item of the example screen is set to 'BSC43', it can be seen that all the base station controllers managed by the mobile switching center managed by the manager are selected for confirmation. Therefore, a failure message occurring in all the sub-equipment or parts constituting the base station controller is displayed on the screen of the monitoring computer.

In addition, when looking at the 'Location' item of the example screen, the location of the failed component is displayed sequentially. That is, BSC05 is the base station controller 5 in the corresponding switching station managed by the administrator, BTS09 is the base station transmitter 9 in the base station controller, BSDC (Base Station Digital Cabinet) 00 is the base station digital cabinet 0 in the base station transmitter, SHELF00 / DCP00 is a failure in component 0 DCP on board 0 of the base station digital cabinet.

In this way, the time zone view allows the administrator to identify at a glance information such as what fault code has occurred on which equipment, how long, how much time has occurred, and when. .

4 is another exemplary screen of analyzing a failure message using the message analysis module 242 according to an embodiment of the present invention.

Referring to Figure 4, it can be seen that the failure message received from the failure message database 232 is analyzed by date. The search period is from April 25, 2002 to April 29, 2002, and the search time for each day is set from 07:00 to 23:00. In addition, the alignment of the failure message is set to SUM, and as in the example screen of FIG. 3, only a specific failure code may be searched through a 'code search' item.

In the example screen of FIG. 4, the number of failure messages generated by each search date and the sum SUM are displayed in the order of the failure messages with the most occurrence occurrences and the number of failure messages during the set search period. Looking at the example screen, it can be seen that there are a number of failure messages that reach nearly 10,000 occurrences. If an administrator attempts to check such a fault message through a simple list screen provided by a conventional fault message monitoring device, it will be a heavy labor that must check a huge fault message of tens of thousands of lines.

However, according to an embodiment of the present invention, the administrator can check the occurrence of the failure message for each device by date, and easily check the bad or malfunctioning equipment and the corresponding parts having a large number of occurrences of the failure message, and immediately follow the recovery and the like. You can take action.

Meanwhile, the item 'alignment ranking' in the example screens of FIGS. 3 and 4 may be 'Location' indicating a location of the equipment in which a failure occurs in addition to 'CODE' or 'SUM'.

It will be appreciated by those skilled in the art that the present invention is not limited to the above embodiments, and that various modifications and changes can be made without departing from the spirit of the present invention.

As described above, according to the present invention, the administrator can analyze the fault message generated in the mobile communication system more efficiently by providing a simple list of fault message screens provided by the fault message monitoring device by time zone, date, and the like. It becomes possible.

In addition, the error messages can be sorted by fault code, by total number of faults, by faulty equipment, or by searching for faults by entering a specific fault code within each time zone or date. Analyze disorders that have occurred in a regular and obvious manner.
