12 _n1 .

In such an exchange, FIG. 7 shows a system configuration diagram in which an old file is operated,
The main control processing processor 101 is in a main operation (indicated by "A" in the figure) state, and the main control processing processor 102 is in a preliminary operation (indicated by "S" in the figure) state. All call control processor 3 ₀ , 3 ₁ , ..., 3 _(n-2), 3 _{(n-1 )}
Are all main operations. The common memory 104 is the main operation,
The common memory 105 is in a state of thermal preliminary operation (indicated as “H” in the figure). The file memory 107 is in the main operation state, and the file memory 108 is in the thermal preliminary operation state. The communication control device 109 is the main operation and the communication control device 110
Is in cold preparatory operation. Signal processor 111 ₀₀
... 111 _n0 is in the main operating state, and the signal processor 1
12 ₀₁ ... 112 _n1 is in thermal preparatory operation. In such a state, when updating the file, the new file is temporarily loaded from the magnetic tape device 106 to the spare file memory 108 (step S800 in FIG. 7).

Next, all processors (101, 102,
103 ₀ , 103 ₁ , ..., 103 _{(n -2),} 103 _(n-1) ,

The new file is sequentially loaded to 103 _{(n-2) and} 103 _(n-1), and the initial setting of each processor is performed. Also, the new file is loaded and initialized to the signal processor 112 ₀₁ ... 112 _n1 , and the system is established in this way (see FIG. 8).

In this state, the file memory 107, the common memory 104, the signal processor 111 ₀₀ ... 111
_{Since n0} is the cold backup state, the file update work is completed when the maintenance person shifts to the thermal backup state (see FIG. 9).

[0006]

However, in the above-mentioned file updating system in the conventional multiprocessor system, the exchange process is completely stopped and the stop time is several minutes. Therefore, there is a drawback that the file updating work can be performed only at midnight when the traffic is low.

An object of the present invention is to solve the above-mentioned drawbacks and to provide an uninterrupted file update system capable of performing file exchange without interruption of the exchange process.

[0008]

In order to achieve the above object, a non-disruptive file updating system of the present invention comprises a signal processor for executing switched signal processing, a call control processor for executing switched call connection processing, and A main control processing processor for executing exchange main control processing, a common memory referred to by the main control processing processor and the call control processing processor,
In the exchange in which the communication control device that connects and controls each signal processor and the file memory that stores the exchange file under the control of the main control processor is provided, and the above-mentioned devices are duplicated, the new file is replaced with the old file. When updating, a part of the main control processing processor, common memory, file memory, communication control unit, signal processing processor and call control processing processor of the standby system is disconnected from the operating system, and a new file from the file memory is the main control of the standby system. After reading to the processing processor and writing to each processor by this main control processing processor, the main control processing processor, common memory, file memory, communication control device, signal processing processor and part of the call control processing processor in which the new file is written It is to switch to the driving system.

Further, the plurality of call control processors are characterized in that when a part of them is used as a standby system, the one having an even number is used as a standby system.

Further, a part of the main control processing processor, common memory, file memory, communication control device, signal processing processor and call control processing processor of the above operating system is a call control after updating the new file with the old file. It is characterized in that it is a standby system except that the processor is connected to the operating system.

In the present invention, the description of the processing for storing the new file in the file memory is omitted, but in addition to the operating system, there are a main control processing processor, a signal processing processor, a common memory, and a communication control device as a standby system. In addition to the fact that there are multiple call control processors, the standby system is disconnected from the operating system, and a part (half) of the multiple call control processors is disconnected from the operating system. A new file was loaded from the spare file memory to the device of the above, the initial settings of these devices were made, the old operation system was disconnected after such switching, and the devices required for the old operation system were connected to the new operation system. It is a thing.
