Abstract

PURPOSE: A BSM(Base Station Manager) failure message analyzing method is provided to extract a failure message outputted from a BSM in an operator's desired format and quickly and easily analyze it. CONSTITUTION: A failure occurs due to some reason while a mobile communication system is being operated(S202). A BSM outputs a failure message(source data) by hexadecimal(S204). Process(analysis) data in an operator's desired format is extracted from the source data by inputting a command language in a shell script sentence(S206). Several process data are extracted from the source data and common points and relationship among the several extracted process data are searched to find out a cause of a failure(S208). A suitable measure is taken according to the cause of the failure to thereby remove the cause of the failure(S210).

Description

Analysis method of BSM fault message {Analysis method of BSM fault message}

The present invention relates to a method for analyzing a BSM fault message, and more particularly, to a method for quickly and easily analyzing a fault message output in hexadecimal from a base station manager (BSM) of a mobile communication system in a desired form. It is about.

A central control and switching center of a general mobile communication system is connected to a base station manager (BSM), a plurality of base station controllers (BSC) and a base station (BTS), and the base station manager A plurality of BSCs are connected to the BSM, and a plurality of base stations (12 or 16 base stations) are connected to one base station controller BSC. (BTS) is connected.

Hereinafter, a mobile communication system will be described with reference to the accompanying drawings.

1 is a functional block diagram of a general mobile communication system.

As shown, the central control and switching center 10, the base station manager 20, the base station controller 30, the base station 40 is composed of.

The central control and switching center 10 controls and monitors the entire system and connects the communication path of the caller and the called party.

The base station manager 20 is connected to the central control and switching center 10 under control and transmits data in both directions, and is made of a work station class computer, and stores a program for controlling and managing the entire base station. At the same time, the program and base station operating parameters are changed.

A plurality of base station controllers 30 are connected to the base station manager 20, and are operated by downloading a program from the base station manager 20.

The base station 40 is connected to the base station control unit 30, a plurality of download the program from the base station control unit 30, downloads and receives the required operating parameters from the base station management unit 20.

Specifically, the base station controller 30 controls and monitors the entire base station controller, processes a call, which is a communication path connection process, and converts a voice signal into a digital signal (Vocoding).

The base station 40 controls and monitors the entire base station, and controls and manages a clock signal, a time and a frequency operated by the base station.

In addition, it controls and monitors digital channels transmitted and received from the base station, and controls and manages a high frequency generator for each channel assigned to the base station.

When a fault occurs during operation in the mobile communication system having the above configuration, the fault output from the BSM 20 is output in the F3000 format.

The following shows only the user data (USRDATA) as an example of the error message output in F3000 format.

As described above, in order to find the cause of the failure message displayed in hexadecimal, it is very cumbersome and time consuming because each number displayed in hexadecimal in F3000 and F3000 map (MAP) must be analyzed in turn. .

In addition, in order to grasp the association of the failure message, it is necessary to analyze the dozens of failure messages as described above to find a common point, which is more difficult in that regard.

In other words, in order to determine the cause of the failure, dozens of failure messages output in the F3000 format must be analyzed to find common ground, which has a very difficult problem of finding the common ground.

An object of the present invention devised to solve the above-described problems, BSM that can extract the failure message output in the F3000 format from the BSM in the form desired by the operator, easy to analyze the message and shorten the time required for analysis It is to provide a method of analyzing fault messages.

In order to achieve the above object, the present invention provides a first step of generating a failure message (raw data) in hexadecimal by the base station management unit (BSM), in which a failure occurs during operation of the mobile communication system, and the shell in the raw data. (SHELL) Inputting a command with a script statement to extract processing data in the form desired by the operator, and extracting several processing data from the raw data by repetition of the above-mentioned first and second steps and having commonalities in the processing data. And a fourth step of finding out the cause of the failure, and a fourth step of removing the cause of the failure by taking appropriate measures according to the cause of the failure. do.

COMPLETED

In the raw data, a command is input to a shell script statement in the same order as in the following embodiment to extract processed (analyzed) data in a form desired by an operator (S206).

1. Copy sgrep.awk under the ~ / tool directory.

2. Open vi .cshrc in your home directory and type:

alias samdol 'awk -f / home1 / cdmaone / tool / sgrep.awk'

Go to the f3000 directory and use:

1) tail -f 15.F3000HD (f3000 file by time zone) │mgrep BSC_00 / BTS_00 (desired base station address│SHELL SCRIPT

2) mgrep BSC_00 / BTS_00 (desired base station address) -i 15.F3000HD (time f3000 file) │ SHELL SCRIPT> (file name)

The following is an example extracted in the form desired by the operator.

[18:00:02] BSC_00 / 03 / S1 / F04..ABN_SCCP_RE_IN_SETUP [RFC_17] _ [DISC_80] *-* ATPff_SO03_TC09_CN011237788400000_B0_CP0_CE00

The extracted example is a base station (BSC_00 / 03 /), sector (S1), frequency allocation (F04), F3000 cause (ABN_SCCP_RE_IN_SETUP [RFC_17] _ [DISC_80]), BSC processor (ATPff) number, service option (SO03), BSC vocoder number (TC09), caller number (CN011237788400000), base station relay line number (B0), base station main vocoder number (CP0), and base station sub vocoder number (CE00).

Looking at the configuration of the analysis (processing) data, each information is composed of a combination of the English letters representing the title and the number representing the actual data, each of the above configured information is arranged in the order desired by the operator, the detailed information I can identify it quickly.

Next, a plurality of processing data is extracted from the raw data by repetition of the above steps, and the cause of the failure is found by finding commonalities and associations in the extracted various analysis (processing) data (S208).

Appropriate measures are taken according to the cause of the failure to remove the cause of the failure (S210).

As described above, according to the present invention, an error message output in the F3000 format from the BSM can be extracted by the operator in a desired form, the message can be easily analyzed, and the time required for analysis can be shortened.

In addition, the cause of the failure can be analyzed and appropriate action can be taken promptly according to the cause of the failure, thereby saving manpower and time.
