Abstract

PURPOSE: A method for controlling an operation parameter of a mobile communication switching system is provided to prevent an abnormal operation by automatically verifying and reporting important operation parameters to a PLD(Process Load Data). CONSTITUTION: As a verification process of a PLD starts a verifying operation, the verification processes collects verification-subject parameter information(S101) and checks a target parameter(S102). The verification process checks whether the target parameter has an error(S103). If there is no error in the target parameter, the verification process drives a timer to periodically check another target parameter(S104). If there is an error in the target parameter, the verification process reports the error to a failure/configuration process(S105). Upon receiving the error message of the specific target parameter, the failure/configuration process outputs a failure message together with the problematic parameter information(S106) and checks whether a parameter is to be automatically changed by the configuration process automatically changes a parameter(S107). If the configuration parameter is set for an automatic change, the specific target parameter is forcefully changed(S108).

Description

Control method for operation parameter of mobile communication exchange system

The present invention provides a mobile communication switching system, in particular, to automatically verify and report operational parameters important to operational parameters in the PLD, to prevent abnormal operation that may be caused by incorrectly specified parameters, or to move quickly. The present invention relates to a method of controlling operating parameters of a communication switching system.

In general, a mobile communication system is a system that allows a mobile station (mobile terminal) to move while receiving a communication service.

1 is a block diagram illustrating such a general mobile communication system.

As shown here, an exchange station 1 which transmits a call processing request of the mobile station 5 to another communication network such as a public switched telephone network through a public network or a dedicated network so that a mobile communication service can be made; A base station manager (BSM) 2 which generally controls the control station 3 and the base station 4; A control station (3) under the control of the BSM (2) and transmitting / receiving messages with the switching center (1); A base station (4) which transmits a call transfer request of the control station (3) to the mobile station (5) and receives a call processing request of the mobile station (5); It consists of a mobile station 5 which is operated while moving or stops at a point which is not specified, and receives mobile communication service in the coverage area of the base station 4.

In the general mobile communication system configured as described above, when the subscriber intends to use the mobile communication service while having the mobile station 5 within the coverage area of the base station 4, the control station 3 controls the base station 4 to determine. The subscriber's mobile station 5 information (ESN, Electronic Serial Number, terminal unique number) is transmitted to the switching center 1. Therefore, in the mobile communication system, the mobile communication system operates to perform the voice information service or to connect with another communication network according to the request of the mobile station 5 to perform the mobile communication service. And the operator performs the control and maintenance function of the control station 3 via the BSM (2).

Here, in a mobile communication system such as PCS (Personal Communication System) Code Division Multiple Access (CDMA), there is a need to increase cells in a base station as the terrain of a specific region changes during system operation.

As described above, in order to expand a cell in the base station 4, the base station 4 currently in use is down and the call service is stopped. In addition, hardware installation is performed according to cell extension using the necessary hardware method, and cell management is performed according to cell extension by deleting / adding the base station 4 currently used or changing the shape of the entire system.

At this time, the BSM 2 stores processor load data (PLD) including various executable files of the control station 3 and the base station 4 and downloads them when the control station 3 requests loading. The control station 3 stores a file and a PLD to be executed in the base station 4 which has been loaded, and then downloads it when the loading request is received from the base station 4. Then, the base station 4 reads the contents of the PLD and activates hardware related to the corresponding cell to perform call service.

However, the current subscribers have a problem in that the call service is interrupted as long as the system configuration is changed to receive the mobile communication service.

In addition, since the configuration of the system needs to be changed, parameters and variables of the base stations must be reset, and if a mistake of the operator occurs in this process, there is a problem that a long time should be input to tune the output of the base station.

As such, many operating parameters are stored in the PLD configured for controlling various systems in the mobile communication switching system, and operators can change / specify the operating parameters stored in the PLD. If incorrect values are specified due to such changes or assignments to operational parameters or manufacturing mistakes in the PLD, normal operation may be impeded.

At this time, in order to determine whether an operation parameter value is wrong, it is necessary to display and compare parameter information with a command one by one. In comparison, it is inconvenient to check and measure what parameter is wrong.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a method for operating operating parameters of a mobile communication switching system that automatically detects and reports operational critical parameters in a PLD of a mobile communication switching system. have.

Another feature is that when an operator sets / changes an operational parameter or specifies an incorrect value due to a manufacturing mistake in the PLD, the operator can detect the parameter error and force the operator to change the parameter value automatically. The purpose of the present invention is to provide a method of operating operating parameters of a mobile communication switching system.

In order to achieve the above object, the operating parameters of the mobile communication switching system according to the present invention,

Collecting verification parameter information when the verification process of the PLD starts;

Checking the target parameter and confirming an error if the verification target parameter is collected;

Reporting a failure / configuration process when a specific target parameter is an error as a result of the determination and outputting a failure message in the failure process;

And automatically changing in the configuration process when the failure message is output by the failure process and forcibly changing parameters in the configuration process.

Referring to the accompanying drawings, the operation parameter operating method of the mobile communication switching system according to the present invention as described above is as follows.

First, a permanent processor for verifying the PLD value is placed in a base station manager (BSM), and a parameter is periodically checked using a timer to detect a parameter that may interfere with normal operation. ) Generates a fault message with the information of the parameter in question and takes action.

To this end, the PLD verification processor collects parameter information for verification, and the collected information can be changed by the operator. The PLD's verification processor resides in the base station manager and periodically checks the verification target parameters. If there is a problem, the PLD's verification processor delivers the problem to the failure process or configuration process and outputs it to the base station administrator's console. To force the parameter to be changed, thus preventing abnormal operation due to incorrect parameter values.

3 is a flowchart illustrating a method of operating operating parameters of a mobile communication switching system according to an exemplary embodiment of the present invention.

When the verification process of the PLD starts a verification operation, the verification target parameter information is collected (S101), and the target parameter is checked among the collected verification target parameter information (S102).

At this time, by checking whether the target parameter is an error (S103), if an error does not occur, proceeds to step S102 to periodically check another target parameter by driving a timer (S104), and when an error occurs, a verification process. Is reported to the fault / configuration process (S105).

In this case, when the error / configuration process reports an error message of a specific target parameter, the error / configuration process outputs a failure message together with problematic parameter information (S106), and checks whether the parameter is automatically changed by the configuration process (S107). In this case, if the configuration process is set to automatic change, a specific target parameter is forcibly changed (S108).

Meanwhile, when reporting an error parameter to the fault / configuration process, a timer can be driven to continuously detect an error for other parameters.

As described above, according to the operating parameter operating method of the mobile communication switching system according to the present invention, collecting information on the operation parameters important to the operation in the PLD and periodically checks whether there is an error, report to the operator when a failure occurs and By making a forced change, there is an effect that can prevent and quickly handle the abnormal operation of the system.

In addition, there is an effect that it is possible to automatically detect the human error that can occur when entrusting the verification of the operating parameters to the operator to quickly act.
