Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading system for loading station data into an area of a main memory accessed based on a call processing procedure in an exchange, and a call processing for station data stored in the main memory. And an addressing method for obtaining an address of an area to be accessed in the process of.

[0002]

2. Description of the Related Art Software for subscriber line exchanges and private branch exchanges has attributes, numbers, and service classes (for example, outside line calls and special number calls) for individual terminals (for example, telephones, data terminals, etc.) accommodated therein. Call and interrupt call permission / prohibition), station data indicating allocation of functions to function buttons, and the like, and a program for sequentially processing calls originating to individual terminals based on the station data.
Further, such a program is loaded on the main memory provided in the exchange together with the above-mentioned station data.

FIG. 7 is a diagram showing a configuration example of a conventional loading method. In the figure, switch 71 is connected to a plurality of terminals 72 ₁ to 72 _N and the public network, and the main storage unit 7
Have three. Further, the exchange 71 is connected to the operation unit 74, the display unit 75, and the external storage 76.

In the loading system having such a configuration,
The load module generated by linking the object module of the program that has been changed as desired and the object module of the station data that has not been changed at all is stored in advance in the external storage 76. The exchange 71 automatically activates the initial program loader when the power is turned on, and otherwise activates the loader based on a command given via the operation unit 74 and the display unit 75. These loaders sequentially read the above-mentioned load modules from the external storage 76 and store them in a predetermined area of the main storage unit 73. Therefore, the exchange 71 processes the calls originated in the terminals 72 _{1 to} 72 _N based on the station data and the program thus stored in the main storage unit 73, and provides the communication service to these terminals.

In addition, in order to flexibly cope with slight additions and changes of the function of the exchange 71, the above-mentioned station data is generally reserved between the storage areas of the items included in the station data. The area is reserved.

[0006]

By the way, in such a conventional loading method, when the function of the exchange 71 is significantly added or changed, the size of each item of the station data is greatly increased. The above-mentioned spare storage area became insufficient, and the station data had to be newly subjected to language processing (for example, compiling and assembling) in the above-described generation process.

[0007] Further, the station data before change held in the main storage unit 73 includes information such as service classes which are set through the operation unit 74 and the display unit 75 and which are not included in the above load module. included. However, regarding such information, when the structure of station data (for example, the order of items) is changed due to a large addition or change of the function of the exchange 71, the station data is stored in the main storage unit 73. After loading, the operation unit 74 and the display unit 7 are again displayed.
I had to manually reconfigure via 5.

Therefore, in the conventional example, it may take a long time to restart the operation of the exchange 71 using the updated program and station data, or an error may occur in the setting of the contents of the station data. .

It is an object of the present invention to provide a loading method and an addressing method that can surely and quickly start the operation by a new program.

FIG. 6 is a flowchart showing the processing procedure of the new program. The operation of this embodiment will be described below with reference to FIGS. The station data 50 is stored in advance in a predetermined area of the main memory 73. In the process of software generation associated with the addition or modification of the function of the exchange 71, FIG.
The new program 51 and the station data object module are generated in the same manner as in the embodiment shown in FIG. 11, but the new program 51 has a process of performing sequential addressing via the conversion table 52 described later when referring to the station data. Is added.

Further, in such a generation process, for the items A, B, C, D, ... Included in the station data, the addresses a, b, c, d, of the storage areas in the main memory 73, respectively.
A conversion table 52 in which ... is registered is created, is linked with the above-mentioned object module after language processing is performed, and is further subjected to arrangement processing for an area that does not overlap with the data 50 already stored in the main memory 73. Is generated and generated as a load module.

Regarding the contents of the conversion table 52, for example, regarding the items A, B, and D, these contents are not changed and the station data 50 can be referred to as they are.
As for the item C, the contents are added and the size increases, so that the contents of the new station data should be referred to. Therefore, only the item C has an address c ′ different from the storage area of the item C of the old station data. Is set, items A, B,
For D, addresses a, b, and d indicating the storage areas of the corresponding items of the station data 50 are set.

The load module thus generated is loaded into an area of the main memory 73 which does not overlap with the station data 50 by a loader activated in accordance with a predetermined procedure through the operation unit 74 and the display unit 75. (Fig. 5).

The new program 30 performs call processing based on a predetermined procedure. When referring to station data in the course of the call processing (FIG. 5), the conversion table is based on the items to be referred to. 52 (FIG. 5), the address registered in the table is obtained (FIG. 6), and the area on the main memory 73 indicated by the address is accessed (FIG. 5).

Accordingly, even when the station data is not regenerated, the call processing is surely performed based on the station data 50 under the new program 51.

Therefore, the load module generation process associated with the program modification is shortened, and further, the restart of the exchange based on the new program is reliably and promptly performed without manually rewriting the station data 50.

In the present embodiment, since the contents of the station data 50 cannot be directly referred to for the item C, the object module of the new station data is regenerated and included in the load module. The present invention is not limited to such a case. For example, when all the contents of the station data 50 can be referred to by the new program 51, the load module does not include the object module of the station data 50 and the conversion table does not include the station data 50. The address corresponding to each item may be registered.

[0038]

As described above, according to the present invention, for each item of the station data, an address conversion table in which the address of the area actually referred to by the program is registered is provided on the program, and the loader or the program uses such an address conversion table. By referring to such an address conversion table, the area to be loaded and the area to be referred to in the course of processing of the program are specified.

Therefore, when the program is modified in response to the request for addition or change of the function, it is not necessary to regenerate or reload the station data which has not been updated at all unlike the conventional example, and the present invention In the exchange to which the above is applied, work efficiency and cost reduction related to software maintenance and operation can be achieved.
