Abstract

PURPOSE:To secure the continuity of the service without interruption of call service processing even in the case of updating a file in an exchange system. CONSTITUTION:An active system 1A worked on an old file and a standby system 1B storing a new file start the service even on the new file with an asynchronous operation at the time of file replacement while securing the service executed on the old file and the changeover is finished when the processing of the old file is finished. An MM(O)3A (mm(1)3B) of the active system 1A (standby system 1B) stores a program for file exchange respectively and a new call is being inputted to the MM(1)3B under the communication control by a CPU(0)2A and CPU(1)2B and then the call service is executed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an uninterrupted file update processing system, and more particularly to all call services at the time of software file update in a switching system having two systems, an active system and a standby system, for performing a telephone system switching service. The present invention relates to an uninterrupted file update processing method for processing without interruption.

[0002]

2. Description of the Related Art In a telephone exchange service, files are updated frequently to provide new functions. The conventional telephone exchange service does not consider non-disruptive processing, which processes all call services when updating a software file, without interruption, and it is processed by the active system immediately before switching from the old file to the new file. Calls are relieved by transferring only busy calls to the standby system in the call service information.

For example, according to the "file replacement method" disclosed in Japanese Patent Laid-Open No. 57-58493, the active system activates the standby system by the file replacement command, loads the program file from the backup system by the backup file device, and The active system transfers call data during a call to a file memory, and the backup system transfers from the file memory to the main storage device to rescue only the call service during a call and start a new file.

[0004]

In this conventional software file updating method, when switching from an old file executed in the active system to a new file executed in the standby system,
Since it is configured to suspend the service running on the old file, execute the restart process from the new file, and start the service after startup, only the limited one such as busy call is rescued. It was not possible, and there was a problem that the service was interrupted during the restart processing with the new file.

Further, in recent years, service provision by software alone has become mainstream, and files are frequently updated to provide new functions, and it is often impossible to ensure continuity of services provided by the exchange system. There was a problem.

The object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide an uninterrupted file update processing method capable of ensuring service continuity without interrupting all call switching services.

[0007]

SUMMARY OF THE INVENTION In a non-disruptive file update processing system of the present invention, at least a central control unit and a main storage unit have a redundant redundant configuration of an active system and a standby system, and a telephone system exchange service. In the file update processing method that performs the file update processing of the exchange system that performs the above, when updating the software file, in the active system operating on the old file, the processing is continued until all call services currently being processed are completed, and The standby system operated on the new file has a configuration in which the processing for a new call service is started to update the software file without restarting the phase of interrupting all call services.

In addition, the non-disruptive file update processing method of the present invention is a separate operation in which the active system operating on the old file and the standby system operating on the new file are operated independently when updating the software file. Means, call identification means for identifying whether the input call should be executed on the old file or on the new file, and the identification result by the call identification means is monitored to selectively execute either the active system or the standby system. And an execution control unit that determines between the processing devices.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.

In this embodiment, the active system 1 in operation of the old file is used.
A and a spare system 1B storing a new file. Each system has a central processing unit (CPU (0)) 2A, (C).
PU (1)) 2B and main memory (MM (0)) 3A,
(MM (1)) 3B, a communication path device (NW) 4 that functions across both the active system 1A and the standby system 1B, and an input / output terminal 5, and the NW 4 is connected to the active system 1A. ing. M
Each of M (0) 3A and MM (1) 3B has an active system 1
A program for separate operation that operates A and standby system 1B independently, and a call identification that identifies whether an input call should be executed on the old file of active system 1A or on the new file of standby system 1B. Program and the communication control between the CPU (0) 2A and the CPU (1) 2B so as to determine whether to execute in the active system 1A or in the standby system 1B based on the identification result of this call identification operation. A program for execution control for performing is stored in advance.

Input from the MAT 5 instructs the active system 1A to restart a new file in the standby system 1B. Backup system 1B
Then, when the new file is normally started up, the active system 1A and the standby system 1B enter the asynchronous operation mode.

FIG. 2 is a flow chart showing the execution of the call service by the active system 1A and the standby system 1B of FIG. While the active system 1A continues the processing currently being executed, the MM (1) of the standby system 1B provides information about the calling for a new call.
Write to 3B (steps 101 and 102). Backup system 1
B starts the service by this memory information (steps 105 and 106), and sets the control order for NW4 to MM.
(1) Write in 3B (step 107). The active system 1A transmits an order to the NW 4 in response to the NW (network) control information request (step 103) from the standby system 1B (step 104). Operational 1A receives a new call M
Report to standby system 1B via M (1) 3B, standby system 1B
Is executed only for NW control requests from.

[0014]

As described above, according to the present invention, when the file is updated by the software function extension, the switching from the old file to the new file is configured so as to eliminate the phase restart accompanied by the processing interruption. The switching can be executed without interruption of the service, and the continuity of services provided by the switching system can be ensured.
