Abstract

PURPOSE: A trunk line auditing function performing method of an exchanger is provided to easily, quickly and accurately recognize a spot problem and obtain operator's reliability to a system by periodically performing a trunk line auditing function to restore a trunk line and reporting an auditing state report message to an operator terminal. CONSTITUTION: An operator using an operator terminal registers a trunk line audit function for inspecting trunk line data, a CR, a trunk line channel in an MMC instruction word in an CRH(201). The CRH receives a trunk line auditing function performing from an operator terminal, registers the auditing performing function in an auditing registration table, and drives an audit function for every 20ms as registered(202). The CRH calls a library of an SSC to request an audit function for the corresponding resources(203). The SSC checks a range and a state of the corresponding resources for performing the trunk line audit function according to the audit function performing request from the CRH and calls the library of a TCC(204). The TCC determines whether a requested trunk line according to the audit function performing from the SSC is in an idle state or in a busy state(205). If the trunk line is in a busy state, the TCC checks a range of the CR assigned to the trunk line(209). If the range of the CR is normal, it is checked whether an equip number value of the audit-subject trunk line is normal(213). If the EN value of the trunk link of the CR is normal, it is checked whether the current call state registered in the corresponding CR is a defined value(215). If the call state registered in the CR of the corresponding trunk line is a defined value, it is checked whether an initiating time has been registered on the corresponding CR(217). If the initiating time exists in the CR, it is checked whether there exists an ending time(219).

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the present invention.

1 is a block diagram for performing a relay line monitoring function of a switch according to the present invention, an operator terminal 10, a main processor (hereinafter referred to as MP) 20 and a line processor (Line) Processor (hereinafter referred to as LP) 30.

The operator terminal 10 is a terminal that performs a function of outputting the information and monitoring details of a relay line in which a problem occurs as a result of performing relay line monitoring. The terminal line is referred to as a man machine communication command (hereinafter referred to as MMC). A relay line audit function for examining data, a call register (hereinafter referred to as CR), a trunk line channel, and the like is registered in the MP 20.

The MP 20 is an upper processor that performs subscriber and relay call processing, and performs maintenance functions for system state management, and includes a call information management and processing unit (hereinafter referred to as CRH) 21. And a special service control (hereinafter referred to as SSC) 23 and a trunk call control (hereinafter referred to as TCC).

The CRH 21 is responsible for the operation of the CR that manages call resources and status during call processing, and manages on-demand surveillance requirements in the monitoring management table in connection with performing relay line monitoring. As a block for performing the operation, after receiving the relay line monitoring function from the operator terminal 10, the monitoring function is periodically registered in the monitoring registration table for performing the monitoring function periodically, for example, every 200 ms, and the monitoring function every 200 ms. Drive. After that, the CRH 21 registers the monitoring performance function in the monitoring registration table, and then calls the library in the SSC 23 to perform the monitoring function for the corresponding resources (relay line data, CR, and relay line channels). It requests the SSC 23 and releases the CR in response to the CR release request received from the TCC 25.

SSC (23) is in charge of the subscriber special service processing, a block for performing the status check function of various types of subscriber system linked to the relay line monitoring-related relay line, performing the relay line monitoring function according to the monitoring function execution request from the CRH (21) For each range of the corresponding resource (relay line data and CR, trunk line channel), for example MP 20, LP 30, E1 trunk line, channel, etc. 25) Call my library

The TCC 25 is a block that performs relay signal processing, such as R1 signaling in the CIS region (Russia region) and R2 signals in Bangladesh / China, and performs a main function related to relay line monitoring, and is monitored from the SSC 23. Determines whether the relay line state required by the function execution is an idle state or a busy state, requests the LC 31 to initialize the relay line data and the trunk line line state, and requests CRH to release the CR. 21), the monitoring status report message according to each status is reported to the operator terminal (10).

The LP 30 is a peripheral device that monitors the state of each line and controls each line, and has a line control unit 31 (hereinafter referred to as LC).

The LC 31 initializes the state of the trunk line data and the trunk line in response to the request for initialization of the trunk line data and the trunk line line received from the TCC 25 in the MP 20. Release it.

With reference to the flowchart of FIG. 2, the procedure of reporting the monitoring status report message which performed the monitoring function with respect to the relay line of the switchboard to the operator terminal in the above-mentioned structure is demonstrated in detail.

The operator using the operator terminal 10 registers a relay line audit function to the CRH 21 for examining the relay line data and the CR, the trunk line channel, etc. using the MMC command (step 201).

After receiving the relay line monitoring function from the operator terminal 10, the CRH 21 registers a monitoring performance function for performing the monitoring function every 200 ms in the monitoring registration table and drives the monitoring function every 200 ms registered. Step 202). After that, the CRH 21 registers the monitoring performance function in the monitoring registration table, and then calls the library in the SSC 23 to perform the monitoring function for the corresponding resources (relay line data, CR, and relay line channels). Request (step 203).

The SSC 23 checks the range and status of the corresponding resources (relay line data, CR, and trunk line channel) to perform the relay line monitoring function according to the CRH 21 monitoring request, and the library in the TCC 25. Call (step 204).

The TCC 25 determines whether the relay line requested by the monitoring function from the SSC 23 is in an idle state or in a busy state (step 205).

If the relay line state is idle in the determination step 205, the TCC 25 checks whether there is a CR assigned to the relay line (step 206).

If there is a CR assigned to the relay line in the check step 206, the CRH 21 is requested to release the CR, and then a monitoring status report message, for example, a message indicating that the corresponding CR has been released is sent to the operator terminal 10. Report (step 207).

If there is no CR assigned to the relay line in the check step 206, the check for the relay line state is finished, and the process returns to check the state of the next relay line (step 208).

If the relay line state is busy in the determination step 205, the TCC 25 checks the range of CR assigned to the relay line (step 209).

If the range of the CR is out of the normal range in the check step 209, the CR is left as it is, and the LC 31 is requested to initialize the relay line data and the relay line state connected to the power station (step 210). A report message, for example, reports to the operator terminal 10 that only the relay line data and the trunk line channel have been recovered while leaving the corresponding CR (step 211).

At this time, when the corresponding relay line is a relay line assigned to the route of the NO.7 signaling system, an appropriate release message is transmitted, and when the relay line is assigned to the route of channel related signaling system, the channel release signal is transmitted to the LC 31 (step 212).

If the range of CR in the check step 209 is a normal range, it is checked whether the equipment number (hereinafter referred to as EN) of the relay target to be monitored is normal (step 213).

If the EN value of the relay line in the CR is abnormal in the checking step 213, the LC 31 is requested to initialize the relay line data and the relay line state, and the CRH 21 is requested to release the CR. A message, for example, relay line data, and a message indicating that all resources such as CR and trunk line channel have been recovered are reported to the operator terminal 10 (step 214).

If the EN value of the relay line in the CR is normal in the checking step 213, it is checked whether the current call state registered on the CR is a defined value (step 215).

If the call state registered in the CR of the corresponding relay line in the check step 215 is an undefined value, the LC 31 is requested to initialize the relay line data, the line state, and the CR, and the CRH 21 to release the CR. After the request, a monitoring status report message, for example, relay line data, and a message indicating that all resources such as CR and trunk line channel have been recovered are reported to the operator terminal 10 (step 216).

If the call state registered in the CR of the corresponding relay line is a defined value in the check step 215, it is checked whether a start time is registered on the CR (step 217).

If the start time does not exist in the CR in the checking step 217, it is an abnormal state. Therefore, the LC 31 requests the LC 31 to initialize the corresponding relay line data, the line state, and the CR, and requests the CRH 21 to release the CR. Thereafter, a monitoring status report message, for example, relay line data, and a message indicating that all resources such as CR and trunk line channel have been recovered are reported to the operator terminal 10 (step 218). If there is a start time in the CR in the check step 217, it is determined whether there is an end time (step 219).

If there is no end time in the CR in the determination step 219, it is checked whether the call state is busy (step 220).

In the check step 220, if the call is not in a busy state, a duration from the start time occupied by the relay line to the present time, for example, 5 minutes has elapsed to check whether the call stays in the call setup step for a long time according to the possibility of the call setup step. Check whether the operation is completed (step 221).

When 5 minutes have elapsed in the checking step 221, the relay line signaling method does not exist so that the LC 31 requests to initialize the corresponding relay line data, line state and CR, and requests the CRH 21 to release the CR. Then, a monitoring status report message, for example, if not in a busy state, is a call setup step, and thus a message indicating that all resources (relay line data, CR, and trunk line channel) have been restored when the time difference between the current time and the start time is 5 minutes or more. Report to operator terminal 10 (step 222). If 5 minutes have not elapsed in the checking step 221, since the relay line signaling method exists, it is returned normally (step 223).

If there is an end time in the CR in the determination step 219, since the call is completed, it is checked whether 5 minutes have elapsed by calculating a difference from the current time (step 224). When 5 minutes have elapsed in the check step 224, the LC 31 requests the LC 31 to initialize the relay line data, the line state, and the CR according to the abnormal state remaining in the long call release step. 21), the operator status report message, e.g. call recovery phase, if the time difference between the current time and the end time is more than 5 minutes, all resources (relay line data and CR, relay line channel) have been recovered. Report to (10) (step 225). If 5 minutes have not elapsed in the check step 224, it is a call release step and returns to normal (step 226).

If the call is busy during the check step 220, the EN value of the destination line interworking with the relay line monitored in the CR is checked (step 227).

If the EN value of the interlocking line interworking with the relay line in the check step 227 is abnormal, the LC 31 is requested to initialize the corresponding relay line data, the line state and the CR, and the CRH 21 is requested to release the CR. Thereafter, a monitoring status report message, for example, reports to the operator terminal 10 that all resources (relay line data and CR, trunk line channel) have been recovered (step 228).

If the EN value of the interlocking line interworking with the relay line in the check step 227 is normal, it is checked whether the state of the interlocking line is busy (step 229). If the state of the interlocking line is idle in the checking step 229, the LC31 is requested to initialize the corresponding relay line data, the line state and the CR, and the CRH 21 is requested to release the CR, and then the monitoring state report. A message, eg, reports to the operator terminal 10 that all resources (relay line data and CR, trunk line channel) have been recovered (step 230). If the state of the interlocking line is in a call in the checking step 229, the call is returned normally because the call is in the busy state (step 231).

In the present invention described above, the relay line monitoring function is periodically performed to recover the relay line in the non-recovery state, and then the monitoring status report message, which is the result of the execution, is reported to the operator terminal, so that a faster and more accurate field problem can be identified. This can instill the reliability of the system to the operator and can be used as a verification method for efficient resource management of the system and higher software quality.
