The present invention relates to a method of processing a cut off call (Cut Off Call) in an improved space switch in a wired switch, in particular, when a cutoff call occurs during the call processing, the cutoff call occurrence message and the cutoff call is sent to the operator. The present invention relates to a method of processing a cutoff call in an improved space switch in a wired switch that automatically displays a generated section.

In a conventional cutoff call processing method in a space switch in a wired switch, a cutoff call test command is referred to as a MMC (Man Machine Communication) monitor to determine whether a cutoff call error has occurred. ), The SLC (Space Switch & Data Link Control; hereinafter referred to as SLC) receives the command through SNC (Switch Network Control block; hereinafter referred to as SNC) to determine whether a cutoff call error has occurred. Check At this time, when the cutoff call error occurs, the SLC notifies this fact to INMH (Interconnection Network Maintenance Handling (hereinafter referred to as INMH)), and the INMH displays a cutoff call error to the operator through the MMC monitor.

However, the conventional cutoff call processing method in the space switch in the wired switch is not a function of checking whether a cutoff call error has occurred on-line during call processing, but the cutoff call must be performed by the operator. Since it was possible to check whether a call error occurred, there was a problem that the testing process was inconvenient and time-consuming.

In addition, the conventional cutoff call processing method of the space switch in the wired switch displays only the fact that the cutoff call error has occurred to the operator when the cutoff call error occurs, so that the operator cannot know the exact section in which the cutoff call error occurred. The problem was that the error situation could not be recovered quickly.

Accordingly, the present invention has been made to solve the conventional problems as described above, an object of the present invention in the improved space switch in the wired switch to enable the operator to quickly and accurately cope with the situation of the cut-off call error when the cut-off call error occurs. To provide a cutoff call processing method.

In order to achieve the above object, a cutoff call processing method in an improved space switch in a wireline switch according to the present invention includes an ASP, an MMC monitor, an EC in an MMP, an INMH and an SNC in an INP, and an SLC in a plurality of SLCPs; In a cutoff call processing method using a cutoff call processing apparatus in an improved space switch in a wired switch composed of control memories mounted in a plurality of hardware SSW,

A first step of the ASP outputting a space switch connection request signal to the SNC to perform a call processing operation; A second channel which finds an idle channel in a table managed by the SNC after receiving the space switch connection request signal output from the ASP, and then outputs state information on the corresponding channel of the idle state to the SLC; Steps; A third step of determining, by the SLC, whether the state information of the corresponding channel of the idle state output from the SNC and the state information of the corresponding channel stored in the image table managed by the SNC match; In the third step, if the state information of the corresponding channel of the idle state output from the SNC matches the state information of the corresponding channel stored in the image table, the corresponding SLC is stored in the control memory mounted in the hardware SSW. A fourth step of reading status information on the channel; A fifth step of determining, by the SLC, whether the state information of the corresponding channel read from the control memory mounted in the hardware SSW matches the state information of the corresponding channel of the idle state output from the SNC; If the state information for the corresponding channel read from the control memory mounted in the hardware SSW in the fifth step does not match the state information for the corresponding channel of the idle state output from the SNC, the SLC cutoff call processing signal. A sixth step of outputting section information to the INMH; A seventh step of outputting a cutoff call error display control signal to the MMC monitor after the INMH receives the cutoff call processing signal and the section information output from the SLC; The MMC monitor may be configured as an eighth step of displaying, to the operator, a cutoff call occurrence status message and a section in which the cutoff call has occurred.

Hereinafter, a cutoff call processing method in an improved space switch in a wired switch according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a functional block diagram of a cutoff call processing apparatus in an improved space switch in a wired switch according to an embodiment of the present invention, and a cutoff call processing apparatus in an improved space switch in a wired exchange according to an embodiment of the present invention, EC (Execution Control Block) mounted in the Analog Subscriber Control Processor (ASP) 100, the MMC monitor 200, and the MMP (Man Machine Processor; MMP) 300. EC 310), INMH 410 and SNC 420 mounted in INP 400, and SLCP (Space Switch & Data Link Control Processor) SLC 510 mounted in 500) and control memory 610 mounted in a hardware SSW (hereinafter referred to as SSW) 600.

The ASP 100 is a main processor that is in charge of a system network management function, a state management function of a system, a control function of a subscriber matching device, and the like, and the SNC 420 in the INP 400 to perform a call processing operation upon a call attempt. ) Outputs the space switch connection request signal.

On the other hand, when the MMC monitor 200 receives a cutoff call error occurrence display control signal through the EC 310 in the MMP 300, the MMC monitor 200 receives a cutoff call error generation message and a section in which a cutoff call error message is generated to the operator. It serves to display.

In addition, the EC 310 mounted in the MMP 300 is software that is responsible for the interface between the operator and the device, and when the cutoff call error occurrence display control signal is output from the INMH 410 in the INP 400, the EC 310 outputs the control signal. It serves to retransmit to the MMP monitor 200.

In addition, the INMH 410 in the INP 400 is software for managing a plurality of states of the hardware SSW 600. When the SLC 510 outputs a cutoff call processing signal and section information, it is received. A cutoff call error occurrence display control signal is output to the MMC monitor 200 through the EC 310 in the MMP 300.

On the other hand, the SNC 420 in the INP (400) is a software that searches for the channels of the plurality of hardware SSW (600) and manages the status of the channel, the ASP (100) is a space switch connection request signal If it outputs, it finds the channel of the idle state in the table managed by itself after receiving this, and then serves to output the state information on the channel of the idle state to the SLC (510).

In addition, the SLCs 510 in the plurality of SLCP 500 are software loaded in the SLCP 500, and when the SNC 420 outputs state information on the corresponding channel in the idle state, the SLC 510 receives the information. It is determined whether the state information of the corresponding channel in the idle state and the state information of the corresponding channel stored in the image table managed by the user are identical.

In this case, if the state information of the corresponding channel of the idle state output from the SNC 420 does not match the state information of the corresponding channel stored in the image table managed by the SLC 420, a cutoff call error is generated. As a result, the cutoff call processing signal and the section information are output to the INMH 410 in the INP 400.

However, when the SLC 510 matches the state information of the corresponding channel of the idle state output from the SNC 420 and the state information of the corresponding channel stored in the image table managed by the SLC 420, the hardware SSW 600 After reading the state information on the corresponding channel from the control memory 610 mounted in the), the state information on the channel of the idle state output from the SNC (420) and the control mounted in the hardware SSW (600) It is again determined whether or not the state information of the corresponding channel read from the memory 610 is identical.

At this time, the SLC 510 is the state information for the channel of the idle state output from the SNC 420 and the state information for the channel read from the control memory 610 mounted in the hardware SSW 600. If is matched, the normal call processing function is performed by connecting the corresponding channel.

However, the SLC 510 provides status information on the corresponding channel in the idle state output from the SNC 420 and status information on the corresponding channel read from the control memory 610 mounted in the hardware SSW 600. Does not match, a cutoff call error has occurred, and thus a cutoff call processing signal and section information are output to the INMH 410 in the INP 400.

On the other hand, the control memory 610 mounted in each of the plurality of hardware SSW (600) is a memory for storing the status information for a plurality of channels.

Next, a method of processing a cutoff call in an improved space switch in a wired switch according to an embodiment of the present invention using a cutoff call processing apparatus in an improved space switch in a wired exchange having the above configuration will be described.

2 is a signal flow diagram illustrating a signal flow of a cutoff call processing apparatus in an improved space switch in a wired switch according to an embodiment of the present invention, and FIG. 3 is an operation illustrating a cutoff call processing method in an improved space switch in a wired exchange. As a flowchart, S denotes a step (STEP).

First, when the call is attempted, the ASP 100 outputs a space switch connection request signal to the SNC 420 to perform a call processing operation (S1).

Then, after receiving the space switch connection request signal output from the ASP 100, the SNC 420 finds a channel in an idle state in a table managed by the SNC 420, and then status information on the corresponding channel in the idle state. Is output to the SLC 510 (S2).

In addition, the SLC 510 receives the state information on the corresponding channel of the idle state output from the SNC 420, and the state information on the corresponding channel of the idle state output from the SNC 420 and itself. It is determined whether the state information of the corresponding channel stored in the managing image table is identical (S3). In this case, the SLC 510 determines whether the state information of the corresponding channel of the idle state output from the SNC 420 is identical to the state information of the corresponding channel stored in the image table managed by the SLC 420. In order to determine whether the state information of the corresponding channel stored in the image table is also an idle state.

On the other hand, in the third step (S3), if the state information for the channel of the idle state output from the SNC 420 matches the state information for the channel stored in the image table (YES), the SLC ( 510 reads state information on the corresponding channel from the control memory 610 mounted in the hardware SSW 600 (S4).

Subsequently, the SLC 510 provides status information of the corresponding channel read from the control memory 610 mounted in the hardware SSW 600 and status information of the corresponding channel of the idle state output from the SNC 420. It is determined whether is matched (S5). At this time, the state information on the corresponding channel read from the control memory 610 mounted in the hardware SSW 600 by the SLC 510 and the state information on the corresponding channel of the idle state output from the SNC 420. The reason for determining whether or not to match is to determine whether the state information of the corresponding channel stored in the control memory 610 in the hardware SSW 600 is also an idle state.

In addition, in the fifth step S5, the state information of the corresponding channel read from the control memory 610 mounted in the hardware SSW 600 and the corresponding channel of the child state output from the SNC 420. If the status information does not match (NO), the SLC 510 outputs a cutoff call processing signal and section information to the INMH 410 because a cutoff call error has occurred (S6).

Meanwhile, the INMH 410 receives the cutoff call processing signal and the section information output from the SLC 510 and then outputs a cutoff call display control signal to the EC 310 in the MMP 300. Then, the EC 310 in the MMP 300 receives the cutoff call display control signal output from the INMH 410, and then retransmits it to the MMC monitor 200 (S7).

In addition, the MMC monitor 200 receives a cutoff call display control signal output from the EC 310 in the MMP 300, and then displays a cutoff call occurrence status message and a section in which the cutoff call occurs (S8). Therefore, the operator recognizes that a cutoff call error has occurred through the message displayed on the MMC monitor 200, and further, grasps even the section in which the cutoff call error occurred.

On the other hand, in the third step (S3), if the state information for the channel of the idle state output from the SNC 420 does not match the state information for the channel stored in the image table (NO), the SLC In operation 510, the cutoff call processing signal and the section information are output to the INMH 410 because a cutoff call error occurs, and then the process proceeds to the seventh step S7 (S9).

In the fifth step S5, the state information of the corresponding channel read from the control memory 610 mounted in the hardware SSW 600 and the corresponding channel of the idle state output from the SNC 420. If the state information is identical (YES), the SLC 510 performs an operation of performing a normal call processing operation through a corresponding channel mounted in the hardware SSW 600 (S10).

As described above, according to the cutoff call processing method of the improved space switch in the wired switch according to the present invention, after checking whether or not a cutoff call error has occurred on-line during call processing, a cutoff call error occurs to the operator. By displaying the status message and the exact interval in which the error occurred, the operator has an excellent effect of recovering the cutoff call error in a short time.
