The present invention relates to a mobile communication system, and more particularly, to an apparatus and method for monitoring an abnormal long time call in a mobile communication system.

In general, a Moblie Switching Center (MSC) of a mobile communication system detects call information for a long time and outputs the detected call information to an operator terminal so that the operator can conveniently perform the system.

For long time call information as described above, the CDMA 2000 1x system monitors and controls long time calls by monitoring the long time calls for more than 1 hour once per hour and outputting the results. In the 1x exchange, abnormal long time calls frequently occur due to the lack of the monitoring function for the long time call, causing customer complaints.

Therefore, if the exchange analyzes the long time call at the desired interval by the operator and analyzes the long time call at the desired interval and checks or analyzes the long time call in the periodic monitoring mode through the operator terminal with audible or audible error, It is anticipated that prompt dissipation will greatly reduce customer complaints.

Accordingly, an object of the present invention is to provide an apparatus and method for monitoring an abnormal long time call in a mobile communication system.

The present invention for achieving the above object is a long time call monitoring device in a mobile communication system, the MSC responsible for mobility management, location registration / management, authentication, handover, roaming of mobile terminals in the mobile communication system, and a base station controller The BSM performs the state and configuration management of the hardware and software of the BSM, collects the base station information, monitors the operation of the base station, and the resources of the BSCs connected to the MSC and the BSM for the long-term billing call in the mobile communication system. It analyzes the status and examines the abnormal long time call, and for the abnormal long time call, the LCA performs a visible and audible alarm on the abnormal long time call to the operator PC in connection with the IODPS.

In addition, the present invention is a method for monitoring a long time call in a long time call monitoring device including a MSC, BSM, IODPS, LCA in a mobile communication system, (a) accessing the MSC and whether or not to occupy each resource of the MSC and mutual resources (B) remote access to the BSM to check whether the resources are occupied and mutual resources match; and (c) check the status of each resource of the MSC and the BSC. And checking whether there is an abnormal long time call, and (d) performing a visual and audible alarm on the operator PC in connection with the IODPS for the abnormal long time call.

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

1 illustrates a network configuration of a mobile communication system to which an embodiment of the present invention is applied. Referring to FIG. 1, a mobile communication system generally includes a plurality of mobile stations 100, a base station transceiver (BTS) 102, a base station controller 104, and a base station. It is composed of a control station (Base Station Manager: BSM) 106, MSC (Mobile Switching Center) (112).

The base station 102 serves to connect the exchange and the terminal of the mobile communication network, and performs functions such as terminal maintenance and call channel allocation / release. The base station controller 104 is located between the exchange and the base station to manage base station operations, to manage hardware and software in the base station 102, to allocate and configure resources for call traffic, to collect information on base station operations, and to detect detected failures. Performs functions such as monitoring of the lower device. The MSC 112 is responsible for mobility management, location registration / management, authentication, handover, roaming, etc. of the MS 100.

The base station controller management system 106 monitors the status of hardware and software of several base station controllers, configuration management, base station information collection, monitoring base station operations, and monitors underlying devices related to detected failures and performs command data collection. .

LCA (114) is as a device for analyzing and monitoring a long time, abnormal call generated in a mobile communication system according to the present invention, the programming in Visual C ^++, and the operator searches for a long period of time analyzing call and call abnormally long time period desired, and The result of analyzing the long time call in the inspection or the periodic monitoring mode is notified to the operator PC 110 by an audible and visual alarm in association with the IODPS 108.

That is, the LCA 114 connects to the MSC 112 and automatically executes DIS-LC-INF, DIS-MS-INF, DIS-CALL-INF, and DIS-T-INF to occupy resources for a long time call. Check whether or not the mutual resources match, and also remote access to the BSM 106 to execute the DIS-MLNK-STS automatically to check whether the resources are occupied and whether the mutual resources match. Subsequently, an abnormal long time call is searched from the above analysis result, and the operator PC 110 performs a visible and audible alarm on the abnormal long time call through the In-Out Display Process System (IODPS) 108. Accordingly, when the operator confirms an abnormal long time call that is visually and audible through the IODPS 108, by releasing the resource for the long time call with a RESET-TRK command, the confirmation time for the abnormal long time call is shortened and Recovery processing is also performed quickly.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, a newly provided LCA 114 for monitoring an abnormal long time call in a mobile communication system is connected to the MSC 112 of the CDMA 2000 1x system at step S200, and then the DIS-LC-INF, DIS-MS-INF, DIS-CALL-INF and DIS-T automatically executes -INF to collect status information of each resource of the MSC 112. Subsequently, in step S202, the LCA executes DIS-LC-INF, DIS-MS-INF, DIS-CALL-INF, and DIS-T with the MS-112 for a long time of each resource of the MSC 112. Verify that resources are occupied for the occupied call and that mutual resources match

In addition, the LCA 114 remotely accesses the BSM 106 at step S204 and automatically executes DIS-MLNK-STS to collect status information of each resource of the BSC 104 connected to the BSM 106, and S 206. In step), it is checked whether the resource occupies and mutual resources match for the long occupied call according to the status information of each resource of the BSC 104 collected through the DIS-MLNK-STS execution with the BSM 106. do.

Subsequently, the LCA 114 checks the abnormal long time call from the analysis result of the long time call through the connection between the MSC 112 and the BSM 106 in step S208, and when the abnormal long time call is checked in step S210. In the IODPS 108 through the operator PC 110 performs a visible, audible alarm for abnormal long time call.
