Abstract

PURPOSE:To recover the maintenance operation management state automatically and quickly without any manual work by registering a command inputted in a maintenance operation terminal equipment and executed by an exchange to the storage means of the maintenance operation terminal equipment, reading the command at the restart of the exchange and sending it to the exchange to execute the command. CONSTITUTION:Whether or not a command is required for the execution at the restart of an exchange main body 3 with a command function code inputted from a keyboard 11 is identified and when the command is a registration object command, the command key code inputted from the keyboard 11 is registered at it is in a command registration table 13 in a magnetic disk device 12. When the exchange main body 3 finishes the restart processing and the normal operation is available, the maintenance operation terminal equipment 1 displays a restart message on a display device 10 to inform it to the maintenance personnel, the command registration table 13 in the magnetic disk device 12 and the registered command key code is sent as it is to the exchange main body 3, which executes the command processing as usual.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a restart processing method that recovers the management state that was processed and maintained by a command before restart when restart occurs due to a failure in an electronic exchange. [Prior Art] Conventionally, when an exchange is restarted, maintenance and operation management data that was processed and retained by commands before restarting is lost, such as when the various equipment and lines of the exchange are blocked. In such cases, after the switch had been restarted, maintenance personnel manually re-entered the commands that had been entered before the switch was restarted. [Problems to be solved by the invention] In the conventional system described above, a maintenance person must manage input commands in preparation for when the exchange is restarted. In addition, recovery is delayed because recovery is performed manually by inputting a command after the switch has been restarted, and equipment and lines that were blocked by the command due to a failure before restart are kept in operation until recovery. There are maintenance and operation problems. [Means for Solving the Problems] The restart processing method of the present invention registers commands processed in an exchange in a storage means of a maintenance operation terminal, and when the exchange is restarted due to a failure, a notification is sent from the exchange. receiving a restart notification message, reading a command registered in the storage means, and sending it to the exchange;
By executing the command, the exchange recovers the state processed by the command before restarting.

〔Example〕

Next, the present invention will be explained with reference to the drawings. Referring to FIGS. 1 and 2 showing one embodiment, a maintenance and operation terminal 1 connected to an exchange main body 3 has a display device 10, a keyboard 11, and a magnetic disk device 12 which is an external storage device. A command registration table 13 is provided in the disk device 12 as an area for storing commands input from the keyboard 11.

Next, Fig. 1, Fig. 2, and Fig. 3 (A). The operation of one embodiment will be explained with reference to (B). FIG. 3(A) shows the processing flow of the maintenance operation terminal E when inputting a command. Since the terminal 11 sends the pressed key code directly to the exchange main body 3 via the communication line 2, the exchange main body 3 interprets the sent key code and performs processing according to the command. For example, if the function code of the command is line blocking, the line specified by the command parameter code is transitioned to the blocked state. When the exchange main unit 3 finishes executing the command, it sends back a command completion message to the maintenance operation terminal 1 indicating whether the processing ended normally or with an error, so the maintenance operation terminal 1 displays the command completion message on the display device 10. At the same time, it interprets the command completion message, determines whether the command has completed normally, and if it has completed normally, the command function code inputted earlier from the keyboard 11 is used to register the command function code that needs to be registered for re-execution when the exchange main body 3 is restarted. identify the command,
If it is a command to be registered, the command key code input from the keyboard 11 is registered as is in the command registration table 13 in the magnetic disk device 12. Note that the commands are registered in the command registration table 13 in the order in which the commands were input. Next, on the assumption that the exchange main body 3 has restarted due to a failure in the above state, a description will be given according to the processing flow shown in FIG. 3(B). When the exchange main body 3 finishes the restart processing and becomes ready for normal operation, a restart message is sent to the maintenance operation terminal 1 via the communication line 2, so the maintenance operation terminal 1 sends the restart message to the display device 10. In addition to displaying and notifying the maintenance person, the magnetic disk device 1
Refer to the command registration table l3 in 2 to determine if there is a previously registered command, and if so,
Since the command key code registered in the command registration table 13 is sent as is to the exchange main body 3, the exchange main body 3 executes the processing of the above command as usual. If a plurality of commands are registered in the command registration table 13, the command key codes are sequentially sent from the maintenance operation terminal 1 to the exchange chanting main body 3 according to the registered order.

〔Effect of the invention〕

As explained above, according to the present invention, commands input at the maintenance operation terminal and executed by the exchange are registered in the storage means of the maintenance operation terminal, and when the exchange is restarted, the registered commands are read from the storage means. By sending the information to the exchange and having it execute the command, it is possible to automatically and quickly restore the maintenance operation management status that was processed and maintained by the command before restarting, without any human intervention.

Claims (1)

[Claims] Commands processed in the exchange are registered in storage means of a maintenance operation terminal, and when the exchange restarts due to a failure, a restart notification message notified from the exchange is received and the commands registered in the storage means are A restart processing method, characterized in that by reading and sending the command to the exchange and having the exchange execute the command, the exchange recovers the state processed by the command before restarting.
