Abstract

PURPOSE:To reduce an output time of station data from an exchange, to improve the operation response of a maintenance terminal equipment and to prevent loss of the station data at system-down or the like. CONSTITUTION:When the maintenance personnel reads station data and a read/ write discrimination processing section 24 discriminates a read request, the station data are read from only a storage processing section 23 in a maintenance terminal equipment 16. When the station data are registered/deleted and the read/write discrimination processing section 24 discriminates the write request, the station data are written to both the storage processing section 23 in the maintenance terminal equipment 16 and a storage processing section 21 in an exchange main body 12. When the station data are lost due to system-down or the like, the maintenance personnel gives a command to a transfer processing section 22 to transfer the station data to the storage device 14 (18) whose content is lost from the other storage device 18 (14).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a station data management system of an exchange used when inputting or reading out and displaying station data accommodating subscriber attributes.

[0002]

2. Description of the Related Art FIG. 3 shows a configuration of an exchange according to a conventional station data management system.

In FIG. 3, station data containing subscriber attributes used in the exchange main body 1 is managed in a storage device 2 in the exchange main body 1. In the maintenance terminal 3, the storage device 2
The station data is input to and the station data read from the storage device 2 is displayed.

[0004]

However, the conventional maintenance terminal 3 only displays the station data sent from the exchange main body 1, analyzes the data transmitted from the maintenance terminal 3, and stores the data in the storage device. Data processing such as writing / reading processing to and from the maintenance terminal 3 and transmission processing to the maintenance terminal 3 are all performed in the exchange main body 1. Therefore, when reading a large amount of station data, the load of the central processing unit (not shown) in the exchange main body 1 increases. That is, the processing time is long, the station data output time to the maintenance terminal 3 is long, and the operation response of the maintenance terminal is deteriorated. Further, there is a disadvantage that all station data is lost when the system goes down.

An object of the present invention is to reduce the station data output time from the exchange, improve the operation response of the maintenance terminal, and prevent the loss of the station data when the system is down. To provide a management method.

[0006]

The station data management system for an exchange according to the present invention comprises a first storage means connected to a maintenance terminal for storing station data, and a first storage means connected to the exchange main body for storing station data. No. 2 storage means, read / write means for reading station data from the first storage means and writing to the first and second storage means, and station data stored in the first or second storage means. When one of the station data is lost, the other station data is transferred to either the first or the second storage means that lost the station data.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a station data management system for an exchange according to the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of an exchange according to the station data management system.

In FIG. 1, a storage device 14 is connected to the exchange main body 12. Further, a maintenance terminal 16 is connected to the exchange main body 12, and a storage device 18 is connected to the maintenance terminal 16.

FIG. 2 shows the processing function in this configuration.

In FIG. 2, a storage processing unit 21 is provided in the exchange main body 12, and the storage processing unit 21 is
The station data is written to and read from the storage device 14.

The maintenance terminal 16 is provided with a transfer processing unit 22 that is connected to the storage processing unit 21 and performs a transfer process of station data. Further, a storage processing unit 23 that is connected to the transfer processing unit 22 and the storage device 18 and writes or reads station data is provided.

The maintenance terminal 16 also includes a storage processing unit 23.
A read / write determination processing unit 24 that is connected to the storage processing unit 21 and determines whether to write or read the storage device 18 is provided.

Next, the operation of this configuration will be described.

First, when the maintenance person reads the station data,
When the read / write determination processing unit 24 determines the read request, the read / write determination processing unit 24 reads the station data only from the storage device 18 through the storage processing unit 23 in the maintenance terminal 16.

Next, when the maintenance person registers / deletes the station data, when the read / write determination processing section 24 determines the write request, the station data is written in the storage device 14 through the storage processing section 23 in the maintenance terminal 16. Be done. at the same time,
The station data is written in the storage processing device 18 through the storage processing unit 21 in the exchange main body 12.

When the station data of either the storage device 14 of the exchange main body 12 or the storage device 18 of the maintenance terminal 16 is lost due to a system down or the like, the transfer processing unit 23 performs processing by an instruction from a maintenance person. In the storage device (14, 18) of which the contents are lost, the other storage device (14, 18)
Station data is transferred from 18).

In this way, the central processing unit of the exchange does not concentrate because the data is stored in the storage unit 14 of the main unit 12 of the exchange and the storage unit 18 of the maintenance terminal 16 for writing or reading. Processing is reduced, and the operation responsiveness of the maintenance terminal is further improved.

Further, since the station data is stored in each of the exchange main body and the maintenance terminal, even if one station data is lost when a failure occurs, the other station data can be used.

[0020]

As is apparent from the above description, in the exchange data management system for an exchange of the present invention, since the exchange data in the exchange is stored in the exchange main body and the maintenance terminal respectively, the exchange data when the exchange data is read This has the effects of reducing the processing of the central processing unit and improving the operation responsiveness of the maintenance terminal.

Further, since the station data is stored in each of the exchange main body and the maintenance terminal, even if one station data is lost when a failure occurs, the other station data can be used.
