Description

Monitoring Method of Application Data and Function Flow between Applications in ATM Switching System

The present invention relates to a method for monitoring the transfer data and function flow between applications in an Asynchronous Transfer Mode (ATM) switching system. The present invention relates to a method for monitoring the transmission data and function flow between applications in an ATM switching system that enables parallel monitoring.

The conventional method of monitoring the transmission data and the function flow between the applications executed in the exchange system is to output the contents of the application program to be monitored through an input / output device connected to the processor of the exchange system through a serial port. Therefore, to monitor the transmission data and function flow between applications running on the exchange system processor, first occupy the I / O device of the processor, then delete all the monitoring functions related to other functions and monitor only the application functions that you want to monitor. It was set to watch the behavior of the application.

However, the conventional method for monitoring the transmission data and the function flow between the exchange system applications configured in this way is that only one input / output device is connected to the exchange system processor, so it is inconvenient to share or use together. Avoiding things. Thus, at one point, only people involved in one function (or field) could use it. Therefore, to test the application system, it was necessary to first obtain an input / output device connected to the processor on which the application is executed. This application development method has had a problem that it has been acting as a deterrent to the improvement of productivity of application development because a lot of human and time factors must be invested.

The switching system application execution environment is real-time and parallel, so tracking the exchange of data between applications used so far monitors the progress of the application through a serial transport port directly connected to the processor of the switching system. It was. There is a dedicated debug tool for the switching system, but it is valid for individual unit functional tests but is not useful for system integration tests. The reason is that the timer operation progresses while catching the flow of an application, making it difficult to understand the flow of the application.

The present invention devised to solve the above problems can monitor the transmission data and the function flow of the application program of the exchange system in real time and parallel processing at the workstation connected through the network, not the input / output device connected to the processor of the exchange system. Its purpose is to provide a way to monitor multiple functions independently and in parallel at the same time.

Another object of the present invention, regardless of where the exchange system is located in the network environment, wherever the application flow in the exchange system can be grasped wherever the development of the exchange system applications and system testing work in the same location The goal is to help you develop your application effectively.

A feature of the present invention for achieving the above object is the step of requesting the monitoring of messages from the monitoring program running on the HMI operating system to the application program running on the switching system, and in the application program in the switching system receiving the message monitoring start request Setting a message monitoring mode; checking whether a monitoring target is transmitted to a monitoring program of a workstation each time an execution event occurs in the application program in the switching system; and the monitoring program is set to the message monitoring mode. If present, the application program in the switching system constructs a monitoring message and sends the monitoring message to a workstation; if the monitoring program is not set to the message monitoring mode, the application program in the switching system configures and sends the monitoring message. Omitting and transmitting a message monitoring end request from the monitoring program to the switching system application program.

The present invention can develop an efficient switching system application program by providing a real-time flow of the switching system application program as a technique for analyzing the flow of the switching system application program running in the ATM switching system.

The present invention is a method for analyzing the data flow between applications in an ATM switching system. In an environment connected to the switching system and a network, the application of the switching system operates regardless of the location of the switching system and the location of the analyzer. It provides a way to monitor and analyze what is happening, that is, the data flow of the exchange system application.

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

The abbreviation in the figure is as follows. CCCP is a Call Connection Control Processor. HMI is a human-machine interface. OMP is an Operation and Maintenance Processor.

1 is a configuration diagram of a system for monitoring an application flow in an ATM switching system. Referring to FIG. 1, a configuration of a system for monitoring an application flow in an ATM switching system will be described below.

The ATM switching system is configured to manage most call processing, billing and statistical data collection, and various system resources such as call connection and disconnection using UNI, NNI, and local switch, station data management, and partial station translation processing. And ALS (ATM Local Switch), which performs partial operation and maintenance functions such as status management function and system visual function, centralized station translation and route management, central switch management, and overall ALS resource integration management. Switch). The human-machine interface (HMI) operating system is a common commercial workstation used as an operator matching system for ATM switches. The ATM switching system and the HMI operating system are connected by Ethernet so that the operator can request the operation and maintenance work and call processing data related operations to the ATM switch through the HMI operating system, or the system alarms and faults generated by the ATM switch. It is delivered to the operator through the operating system. The ATM switching system is connected to the HMI operating system alone, so other workstations cannot transfer data to the ATM switch. Since the HMI operating system is an input / output channel (or a window) of the ATM switching system, all conversational procedures with the ATM switching system must pass through the HMI operating system. Other workstations connected via the network (Ethernet) can also communicate with the ATM switching system via the HMI operating system. This network environment allows the monitoring of transfer data and function flows between applications within the ATM switching system, as well as from the HMI operating system and other workstations. Applications in the ATM switching system are always alive 302 when the switching system is up and running so that the workstation's watch program can receive the message watch start 303 and release 312 requests.

2 is a flowchart of a monitoring program at a workstation. Referring to Figure 2 describes the flow of the monitoring program at the workstation as follows.

When the monitoring program is executed 201 in the HMI operating system, a message monitoring start request 202 is made to a processor in a switching system that is executed by a specific application program to be monitored. It waits (203) for a response from the application program to receive the request of the monitoring program. The connection between the monitoring program and the application is instantaneous, and the response from the application is sent 204 in a monitoring message. Whenever the monitoring contents are generated by the application program, the monitoring message is transmitted to the monitoring program of the workstation (204), and the monitoring program receives the screen output (205) and transitions to the monitoring message waiting state again (206). . In this way, it is possible to monitor the contents and function flow of the transmission / reception data in the application program of the switching system. The monitoring program is terminated by stopping execution of the monitoring program. Ending causes the watchdog program to terminate watchdog by generating an interrupt on the keyboard (207). The message monitoring end request 208 is then made to the application program of the switching system and the monitoring program ends 209.

3 is a flowchart of an application message monitoring function in an ATM switching system. Referring to Fig. 3, the flow of the application program monitoring function in the ATM switching system is described as follows.

When the switching system is started up, the application is always alive (301, 302). Upon receiving the message monitoring start request from the workstation in the waiting state 302 (303), the message monitoring mode is set (304) and the response is sent to the monitoring program of the workstation in the monitoring message (305). When an event of a target to be monitored (a request for execution of an operator command, a start of execution by a timer or a report generated by the system, etc.) occurs (307), the target of monitoring (such as transmission data content or control flow) is detected in the process of processing the event. If it meets the message monitoring mode (308), and if the message monitoring mode is set to configure the monitoring message to the monitoring program of the workstation (309), if not set to the message monitoring mode configuration and transmission of the monitoring message Omit the procedure. After performing the generated event 310, the process transitions to the execution request reception standby state 311. Upon receiving the message monitoring end request 312 from the monitoring program, the message monitoring mode is released (313), and the state transitions to the waiting state for receiving the request again (314).

As described above, the present invention uses the network (Ethernet) to monitor the transmission data content or the function (control) flow in the application program in the ATM switching system by using a network (Ethernet) to maximize the use of human and physical resources in the development of the switching system application. The effect is to make it work. As described above, using the workstation monitoring program of the present invention, it is possible to grasp the contents of the transmission / reception data and the function (or control) flow in the application program of the switching system, and thus it can be usefully used to analyze the switching system application program. In addition, it is not dependent on the input / output device resources connected to the processors in the switching system, but because it is connected through the network, it is possible to perform many functions (or fields) independently at the same time, thereby making the best use of human and physical resources, thereby developing the exchange system application. There is an excellent effect to increase.
