Abstract

PURPOSE: A managing method of a work station processor interworking with a switching system is provided for an operator to quickly recognize an operation status of an internal processor of a work processor to instantly and effectively cope with an error in its occurrence to smoothly operate a work station by monitoring the processor of the work station existing outside a switching system by an SSC(System Status Control) and informing the operator of it. CONSTITUTION: An SSC of a switching system transmits the first signal requesting current status information to a processor, and determines the status of the processor depending on whether it receives a response signal to the first signal from the processor(S22). At this time, an operation mode processor receives the first signal from the SSC and transmits the status information related to the current operation mode and a standby mode. In case that a response signal to the first signal is received from the processor of the work station, the SSC analyzes the received data, records the status information of the processor in a data base(S23), and judges whether the processor responded to the first signal is a processor being operated by interworking with the current switching system(S24) . If it is the processor being operated by interworking with the current switching system, the SSC stores the status information of the corresponding processor in the data base(S25). If no response signal to the first signal is received from the processor, the SSC determines that a corresponding processor has not been installed and transmits a work station processor installation signal to an operator(S26).

Description

Method for management of the Workstation Processor internetworking with the switching system}

The present invention relates to a method for managing a workstation operating in conjunction with a switching system. In particular, the SSC (System Status Control) of the switching system monitors the processor provided in the workstation that exists outside the switching system, The present invention relates to a management method of a workstation processor operating in conjunction with an exchange system for quickly identifying an operating state of a station internal processor and smoothly operating a workstation.

In general, in a switching system, a processor is duplexing a processor in a duplication manner in the form of memory replication, and the processor duplication configuration is shown in FIG. 1 includes a central processing unit 1a and a first memory 1b, a second central processing unit 2a and a second memory 2b on the standby mode 2 side.

In the switching system configured as described above, the contents recorded in the first memory 1b on the operation mode 1 side are also recorded in the second memory 2b on the standby mode 2 side. Even when a hardware fault such as a power supply disconnection or a communication line failure occurs on the side, the same data as the operation mode 1 side remains on the standby mode 2 side. The central processing unit 2a can continuously provide services without interruption of operation by continuously operating based on the data of the second memory control unit 2b.

The processor operating in the conventional exchange system as described above includes a hardware alarm processing apparatus and detects an error in the processor and transmits an alarm signal so that an operator can know. In other words, in an exchange system having a redundant processor, a system status control (SSC) is periodically transmitted to check the status of the processor, and receives a response signal from the processor to detect the abnormality of the processor. Judge nothing.

If an error occurs in one processor, the other processor detects this and transmits an error to the SSC. However, if an error occurs in both processors, there is no processor capable of transmitting an abnormality to the SSC. Therefore, the SSC does not receive a response to a periodically transmitted signal. Therefore, the SSC determines that an error has occurred in all processors and transmits a status change and an alarm message to the operator.

However, since the processor provided inside the workstation that is connected to the outside of the exchange system and interoperates with the exchange system does not have an alarm processing device, when an error occurs in the processor, the operator does not know whether the error has occurred. There is a problem.

The present invention has been made to solve the above problems, the operator by the SSC (System Status Control) of the exchange system monitors the processor provided in the workstation that is outside the exchange system to inform the operator of the monitoring information The purpose is to quickly understand the operating status of the processor inside the workstation so that the workstation can be operated smoothly and effectively when an error occurs.

A feature of the present invention for achieving the above object is a method for controlling a workstation processor operating in conjunction with an exchange system, wherein the exchange system transmits a first signal requesting status information to the workstation processor; and; Determining the workstation processor state according to whether a response signal to the first signal is received; In response to receiving a response signal to the first signal, periodically transmitting a second signal requesting status information to the workstation processor in the switching system; Determining the workstation processor state according to whether a response signal to the second signal is received; Periodically transmitting a second signal to the workstation processor.

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

In the present invention, the exchange system and the workstation transmit / receive information to each other by using an Inter Processor Communication (IPC) communication, and the processor provided in the workstation is configured in an active mode and a standby mode. Using the architecture, the operator sends and receives signals at regular intervals through the switching system to monitor the processor status inside the workstation.

Workstations connected outside the exchange system according to the invention are connected as shown in FIG. 2. That is, the workstation 30 and the switching system 20 are connected to a duplex communication cable to transmit / receive information through IPC (Inter Processor Communication) communication. Here, two processors 31 and 32 are provided inside the workstation 30, and the SSC 21 inside the switching system 20 performs all state management and failure handling of the processors 31 and 32. It is in charge of, and connected to the external LAN, the operator can monitor the operating status of the internal processor (31, 32) of the workstation 30 through the switching system 20 from a distance.

In the present invention, a flowchart illustrating the process of requesting status information from the SSC 21 to the processors 31 and 32 of the workstation 30 at the first time the system is set up is shown in FIG. 3.

First, the SSC 21 of the switching system 20 transmits a first signal requesting the current status information to the processors 31 and 32 (step S21), and the processor 31 and 32 for the first signal. The state of the processors 31 and 32 is determined according to whether the response signal is received (step S22).

Here, the operation mode processor among the processors 31 and 32 receives the first signal transmitted from the SSC 21 and transmits state information regarding the current operation mode and the standby mode to the SSC 21.

Herein, the operation in step S22 will be described in detail.

First, when a response signal to the first signal is received from the processors 31 and 32 inside the workstation 30, the SSC 21 analyzes the received data to obtain status information of the processors 31 and 32. It records in the base (step S23), and determines whether the processors 31 and 32 responding to the first signal are currently operating in cooperation with the switching system 20 (step S24).

If the processor is currently operating in conjunction with the exchange system 20, the SSC 21 stores the state information of the processors 31 and 32 in the database (step S25), and the current exchange system 20 If the processor is not operating in association, the SSC 21 returns to step S21 to perform the corresponding task.

When the response signal for the first signal is not received from the processors 31 and 32 in step S22, the SSC 21 determines that the corresponding processors 31 and 32 are not installed and transmits a workstation processor installation signal to the operator. (Step S26).

4 is a flowchart illustrating a process of periodically requesting status information from the SSC to the processors 31 and 32 of the workstation 30 in the present invention.

The SSC 21 provided in the switching system 20 periodically transmits a second signal requesting a current state to the processors 31 and 32 (step S31), depending on whether a response signal is received for the second signal. The state of the processors 31 and 32 of the workstation 30 is determined (step S32). Here, when the operation mode processor among the processors 31 and 32 receives the second signal transmitted from the SSC 21, the operation mode processor transmits state information regarding the current operation mode and the standby mode to the SSC 21.

Thereafter, when the SSC 21 receives a response to the second signal from the processors 31 and 32, the SSC 21 analyzes and stores the received data (step S40).

Here, the process S40 will be described in detail.

The SSC 21 checks whether the status information for the processors 31 and 32 contained in the received data is the same as the workstation processor status information stored in the switching system 20 database (step S41), and the received data is stored in the received data. When the state information of the processors 31 and 32 is the same as the workstation processor state information stored in the database, the SSC 21 determines that there is no state change in the processors 31 and 32 and stores the received data in the database. (Step S42).

In step S41, if the status information for the processors 31 and 32 contained in the received data is not the same as the workstation processor status information stored in the database of the switching system 20, the SSC 21 is the processor 31, It is determined that the state of 32 is changed, and a signal and a message informing the operator of the state change of the processors 31 and 32 are transmitted (step S43), and the process moves to step S42 to store the received data in the database.

On the other hand, when the SSC 21 does not receive a response to the second signal from the processors 31 and 32 of the workstation 30 in step S32, the SSC 21 sends status information to the processors 31 and 32. The request second signal is retransmitted (step S33), and it is checked whether a response to the second signal retransmitted from the processors 31 and 32 is received (step S34).

When receiving a response to the second signal retransmitted from the processors 31 and 32, the SSC 21 analyzes and stores the received data (step S50).

Here, the operation of the process S50 will be described in detail.

Check that the status information for the processors 31 and 32 contained in the data received by the SSC 21 is the same as the workstation processor status information stored in the switching system 20 database (step S51), and stored in the received data. If the state information for the processors 31 and 32 is the same as the workstation processor state information stored in the database, the SSC 21 stores the received data in the database (step S52).

In step S51, when the status information for the processors 31 and 32 contained in the received data is not the same as the workstation processor status information stored in the database, the SSC 21 changes the states of the processors 31 and 32. In response to the determination, the controller transmits a signal and a message informing the operator of the state change of the processors 31 and 32 (step S53), and moves to step S52 to store the received data in the database.

In addition, in step S34, when the response to the second signal retransmitted from the processors 31 and 32 is not received, the SSC 21 determines that the processors 31 and 32 are in a dual down state. The state of the workstation processor is stored in the database of the switching system 20 (step S35), and a signal and a message informing the operator of the down state of the processors 31 and 32 are transmitted (step S36). Here, dual down means that both the operation mode and the standby mode processor of the processors 31 and 32 included in the workstation 30 are down.

In addition, since the SSC 21 cannot be detected in hardware when a problem occurs due to a hardware defect of the processors 31 and 32, the SSC 21 cannot be detected in hardware. 2 If there is no response to the signal, it is determined that the workstation processor is in a dual down state.

As described above, the present invention provides a system status control (SSC) of the switching system to monitor the processor provided in the workstation that is located outside the switching system so that the operator can quickly grasp the operating state of the processor inside the workstation to immediately detect an error. By effectively responding, the workstation can be operated smoothly.
