The present invention relates to a method for controlling the output device according to the characteristics of the message output to the operator in the electronic switchboard.

Electronic exchanges provide PCs (Personal Computers), VDTs (Visual Display Terminals), printers, and Real Environment Function Test Systems (REFTS). These output devices are classified into two types according to their attachment position, and the messages outputted to the output devices are classified into two types. Man-Machine Communication (MMC) messages and voluntary messages indicating the result of the operator's request are provided. For example, there is a system message that inquires the status of the system or informs the system of the change.

The MMC message is determined by the output information of the MMC message so that it is not dependent on the input device. The system message requires this information because the output system information is only needed for a specific operator, not for all operators. Should be output to the output device. In the electronic switchboard, because several processes are executed simultaneously in one processor, different messages may collide in the output device that is the end of the output. Therefore, it is necessary to determine the output device to be output according to the characteristics of the output message and the output device, and to prevent a collision between the output devices.

Accordingly, an object of the present invention is to provide a control method for an output device for selecting an output device to be output according to characteristics of a message and for preventing a collision between output messages in the output device.

In order to achieve the above object, the present invention provides a call processing function and an ASS (Access Switching Subsystem) which performs its own operation and maintenance, the overall maintenance and operation of the system, test and measurement, statistics, and auxiliary storage devices. CCS (Central Control Subsystem) which performs control management and matching function with the operator and other systems, and intensive function such as number translation, route control function, and space switch connection among call processing functions In the method of controlling the output device of an electronic switching system comprising an INS that generates and distributes a system clock and connects the ASS to each other or between the ASS and the CCS, the output information is extracted when an MMC message is configured in a meaningful unit. A first step of outputting the MMC message to the corresponding output device when the MMC message is output to the device inputted by the output information; When the output information search result indicates that the output information indicates the bypass output of the MMC message, if the status of the output device to be bypassed is inquired and accepted, the output is output to the bypass output device. The second step of forcibly outputting to a device, if the system message is configured in a meaningful unit, extracts and retrieves output information, and if the output information indicates an outputable state, a message spool of the corresponding output device capable of outputting the system message. : A third step of storing and managing in a Simultaneous Peripheral Operation On-Line, and a fourth step of outputting a system message stored in the system message spool to the corresponding output device.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a hardware configuration diagram of an electronic switching system to which the present invention is applied, 2 is an INS (Interconnection Network Subsystem), 3 is an Operation and Maintenance Processor (OMP), 4 is a Man-Machine Processor (MMP), and 5 is a central CCS. Control Subsystem), 6 denotes an operator, 7 denotes a printer, and 8 denotes an ASS (Access Switching Subsystem).

The hardware of the electronic switching system to which the present invention is applied has a subscriber and trunk line interface, a time switch, various signaling devices, and a packet processor as shown in FIG. 1 to provide most call processing functions and its own operation and maintenance. ASS (8) performs the overall maintenance and operation of the system, test and measurement, statistics, control management of auxiliary storage devices such as magnetic tape unit (MTU) or disk unit (DKU), and with the operator and other systems. It performs matching function, performs CCS (5) consisting of OMP (3) and MMP (4) and centralized functions such as number translation, route control function, and space switch connection among call processing functions. It consists of an INS (2) that generates and distributes system clocks and connects the ASS (8) with each other or between the ASS (8) and the CCS (5) with an optical link.

The Man-Machine Subsystem (MMS), which is responsible for the input / output functions between the operator and the system, is processed by the Man-Machine Processor (MMP) 4 in the CCS (5). The operator matching function performs not only direct input / output function but also window function, menu and form writing function, and system operation recording function to provide the operator's convenient environment. PC (Personal Computer), VDT (Visual Display Terminal), Printer, etc. are used as a device for matching between operator and system. The operator communicates with the system through the input / output device.

In addition, the application program for generating the output message of the electronic switchboard is mounted on the processor, and the output message is generated by the MMC or the system itself, and then delivered to the operator.

When an event that generates an output message occurs, the application program calls a user procedure that can send output data and sends the data to be output from the application program to the output processing routine in the MMP. The output processing routine formats the transmitted data into ASCII character strings that the operator can recognize and classifies them into meaningful units.

2 is a flowchart of a method of outputting an MMC message to an output device according to the present invention, and shows a process of outputting an MMC message divided into meaningful units to an output device.

Output information is indicated by 2 bits, and the first bit indicates output prohibit / release function. 0 means output and 1 means output prohibit. The second bit indicates the bypass output function of the MMC output message. 0 means output to the input device and 1 means bypass output. The initial data of the two information indicates the message output deactivation state (0) and the bypass output prohibition state (0). However, since this information can be changed by an operator's MMC command, the information can be changed to the message output prohibition (1) or bypass output (1) state. The output prohibition / cancel function among the message output information is the function to output or prohibit the output of the message, and the bypass output function is to output the output message to the MMC input device or to the output device designated by the operator.

If the message is divided into meaningful units, the output information of the corresponding message is extracted (201), and the output of the MMC message is searched (202). If the output information is B'00 indicating that the output message is output to the device inputted, (203) Since the output message can be outputted, the corresponding output device driver is called to output the output message (204) and ends (205).

The output information ends without processing the process for outputting the B'10 206 indicating the message output prohibition (207).

If the output information is B'01 or B'11 indicating the bypass output of the message (208), the device status of the number of the output device to be bypassed is inquired (209), and the output device can receive the bypassed message. Cognitive search (210). If the output device can receive the bypass message (211), the driver of the bypass output device is called to output the output message (212) and ends (213). If the output device cannot accept it (214), the output device is forcibly outputted to the original output device (215) and then ends (216).

3 is a flowchart illustrating a method of outputting a system message to an output device according to the present invention, and shows a process of outputting a system message configured in meaningful units to the output device.

The system message is different from MMC message, so there is no input device. Therefore, the output information is only for output prohibition / release and not required for all output devices.

And the people who need system messages are the operators that operate at the system level, not the operators who do some work. This system message is printed to the operators who work partly, which may interfere with the operation. Therefore, it is necessary to output only to an output device capable of outputting system messages.

When the system message is configured in a meaningful unit, the output information is extracted (301), and whether or not output is prohibited (302). That is, if it is a status message and the output prohibition state (303) cannot be outputted, it returns to the original state for the next processing (304). If it is a status message and not in the prohibition state (305), it can be outputted and stored in the message spool (SPOOL: Simultaneous Peripheral Operatin On-Line) of the corresponding output device capable of outputting the system message (306). Then, the process of managing the stored message spool transmits that one message has been stored (307), is outputted, and returns to its original state (308).

4 is a flowchart of a system message spool management method according to the present invention.

First, upon receiving the message storage notification signal of the spool (309), it requests to occupy the output device (310), and returns to its original state (311). Upon receipt of an output device occupancy signal or upon receipt of a system message output end notification signal (312), the system message is checked to see if it is in the spool (313), if not (314) and returned to its original state (315), and if it is (316) the system message. The message is extracted from the spool (317), output to the corresponding output device (318), and returned to its original state (319).

According to the present invention configured and operated as described above, the output device is changed according to the type of the message, so that the association between the MMC message and the system message can be eliminated and variously operated according to the characteristics of the output device. There is an application effect to prevent the collision.
