Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a service program provision management system for providing various services in an electronic exchange, and in particular, service provision conditions can be automatically created by incorporating a ROM chip into the system. Concerning what was done.

Prior Art and Problems Conventionally, services provided by private electronic branch exchanges include, for example, internal intercom service, call forwarding service,
There are over 100 types of services such as pick-up services, and each requires its own program to perform these services. By the way, not all users perform all types of these services, and which service to perform is determined by the user's choice. Therefore, each user has to decide which service to perform. It is necessary to use different service programs depending on the content.

For this purpose, as shown in Figure 1, the user stores a service program corresponding to the service to be executed on the magnetic tape MT, operates the electronic exchange, and uses the central controller CC.
transfers this service program from the magnetic tape MT to the main storage device via the magnetic tape controller IOC.
It is deployed to MM and various services are executed accordingly. In Figure 1, NW is a network, SUB is a subscriber, and TK is a trunk. Of course, the service program may be expanded from a user file stored in advance on a floppy disk FD instead of the magnetic tape MT.

Now, the user is using service programs A, C...
When using , the program provider will create a user file by adding service conditions for each user from the user file in which all service programs are stored. A service acceptance/disallowance table for all service programs had to be created and provided with the program for the user to use. In this service permissibility/disapproval table, permissible information and non-permissible information are written for all service programs, and for permissible service programs, the permissible conditions (for example, the level at which you can receive call forwarding service) are written. In addition, the service permissible and non-permissible table development area, service condition development area, service program development area, etc. are entered in the main memory corresponding to the user.

When a user executes a service using these service programs, as shown in Figure 2, the service module management table SMNDT, task determination table STNDT, and service conditions are first stored on the main storage device MM from the magnetic tape MT, which is the user file. It stores service data SMNd, service programs A, C, . . . in which task determination table addresses are entered. These loading operations are carried out by the central controller CC using its own programs.

In this case, if the user does not desire service program B, the corresponding item SMNb on SMNDT is set to "0" in the service allowable/disallowable table on the magnetic tape MT, which is the user file.
Correct address B of the item on STNDT to "0".

Therefore, when executing service D, the central controller CC first accesses SMNDT on the main memory MM to search whether SMNd is "0" or not.
If it is not "0", access SMNd and read the service conditions and STNDT address. and STNDT if the service conditions are satisfied.
Obtain the address A where the task for executing the service program A is written from the corresponding item,
This causes the service program A to be read and the intended service to be executed.

If the request from SUB is for service B, which is a non-permissible service, CC reads SMNb and recognizes that the service is non-permissible since it is "0", and requests SUB to , for example, will transmit a busy tone.

However, in such a conventional service program providing method, it is necessary to create a service permissible/disallowable table indicating permissibility/disapproval for all service items. And when expanding this user file onto main storage MM,
SMNDT, SMNd, STNDT, service program areas, etc. also had to be modified to the data for each user determined by the user's specifications. Therefore, since the services implemented for each user are different and the loading status is also different, when it becomes necessary to modify data after loading, it becomes a difficult task to modify the data after loading.

Purpose of the Invention In order to improve such problems, the present invention provides a service permissible data storage unit, a standard data storage unit, and a service program storage unit regarding service items that allow services, and stores service permissible data based on standard data. It is an object of the present invention to provide a service program provision management method in which a service program is provided within a fixed area in a system within a device.

Structure of the Invention In order to achieve this object, the service program provision management method of the present invention provides an electronic switching system that executes a plurality of selected service programs selected by a user from among a plurality of service programs that provide various different services. ,ROM
a management information holding unit that holds management information for managing the selected service program; an execution service program holding unit that holds the selected service program; and a storage device of the electronic exchange that stores the management information. A standard data holding unit that holds standard data indicating a storage location is provided, a memory area of the storage device is secured in the storage device of the exchange based on the standard data, and a service/module management table of the management information, the service - Allocate each address of the linked data area of the module management table and the task determination table, then store the address of the linked data area in the service module management table according to the management information, and set the service module number. accesses the service/module management table to store service conditions, etc., creates a task determination table as needed for the service/module number, and retains this task determination table and the execution service program in the ROM. The switching system is characterized in that it is possible to provide the above-mentioned user-compatible switching system by establishing a linkage between the service program and the address of a necessary service program.

Embodiment of the Invention Before describing the present invention in detail based on one embodiment, its outline will be explained with reference to FIGS. 3 and 4.

Fig. 3 is an explanatory diagram before system startup, Fig. 4a is a schematic explanatory diagram when creating the service module management table SMNDT and task determination table STNDT in the main storage, and Fig. 4b is an explanatory diagram before system startup. It is an explanatory view after raising.

In the present invention, a ROM is prepared in which only the services used by the user are written. This ROM contains management information (detailed in Figure 5) as shown in Figure 3, etc.
, service program SP, and editing program
PR, standard data SD, etc. are stored. Standard data is SMNDT created from management information and
Information on which area of the main storage device STNDT etc. should be stored in and link information within SMND, which will be described later, are entered and are unique to the system.
As shown in Figure 4A, standard data is first read out by the editing program PR in this ROM, and SMNDT and STNDT are stored in a specific area in the main storage device defined by this standard data based on the management information.
etc. are created. When the system starts up, it will be in the state shown in Figure 4 (B). When a service is to be executed, the central controller CC accesses SMNDT to search whether the service is executable or not, and if it is executable, STNDT is executed. Access is made to obtain the ROM address where the executable service program is stored, and from this the required service program is read from the ROM.

Next, one embodiment of the present invention will be described in detail based on FIG. 5, with reference to other figures as necessary.

The ROM stores management information CON, service program SP, editing program PR, and standard data SD. This ROM is provided to the user by the program provider. In this case, a large number of service programs A, B, C...
An example will be described in which A, B,... are provided, and C... is not provided.

The service program SP stores selected service programs selected by the user to be executed.
If A, B... are selected from B, C... and C... is not selected, the selected programs A, BB...
Only C is stored, and unselected C... are not stored.

Management information CON indicates selected programs A and B.
A ROM in which service permission information indicating... is stored, and for each permitted service, its service module number SMN, its service conditions, and service program are stored.
The starting address α of is stored.

The editing program PR is the management information for this ROM
This program has an editing function that creates SMNDT and STNDT in the data area specified by the standard data described later according to CON, and also writes the address linkage for the selected program.

Standard data is stored in the storage device as described above.
The SMNDT, STNDT, and address linkage are predetermined, fixed to this system, and common to each user.

Next, we will use this ROM to explain the IPL operation at system start-up in the electronic exchange.

(1) First, when starting up the system, the CC uses the built-in program to run the ROM editing program.
Read the PR. Then, based on the standard data stored in the ROM by this editing program PR,
Secure the memory area of the storage device and use it for services.
Allocates addresses for data areas (for SMNa, SMNb, etc.) linked to module management table SMNDT, task determination table STNDT, and SMNDT.

(2) Next, the editing program PR is the ROM management information
Perform the following processing according to CON.

When ROM creation information is “1”, SMNDT
In order to create a program, the address indicating the storage location of the service condition H of the service program A is set in the category A of the service module number.
Fill in SMNa.

Next, service module number (SMN) A
Access this SMNDT, read out the address SMNa where the service conditions are entered, and extract this area.

Then, read out the service condition H from the ROM management information and apply it to the address extracted above.
Store in SMNa.

Next, when the ROM creation information in the ROM management information is "2", STNDT is created.

Then, this STNDT is indexed by the service module number (SMN) A, and the storage address α in the ROM where the service program A is stored is set in the corresponding area.

The above steps are repeated sequentially as the management information is read out, and when all of the management information in the ROM is read out, service provision data is automatically set in the storage device. At this time, no data is entered for service-unacceptable programs, for example, service program C, so SMNDT
The area of section C of STNDT is filled with "0", indicating that no linkage of the next address for indexing the service conditions has been established.

After the system starts up in this way, it will be in a state as shown in Figure 4B, and the data in the storage device will be
The service will be executed by the ROM's service program.

For example, when a subscriber requests execution of service B, CC first accesses section B of SMNDT, reads SMNb, recognizes condition i, and if the subscriber conforms to this condition, the CC requests execution of service B from STNDT. The service program B will be read out and the service will be executed. At this time, service program B
For the operation of the service, the additional service program for the application is referred to as necessary to execute the service.

Effects of the Invention According to the present invention, by providing the user with a ROM in which only the permissible information for the user is written, the user automatically develops the necessary information in a predetermined area of the storage device and stores the necessary information accordingly. Since a predetermined service can be executed, the conventional inconvenience of having to create unacceptable information when providing a service is eliminated.

Moreover, standard data allows the deployment in the storage device to be common to all systems.
Unlike in the past, implementation methods differ for each user, and modifying data after loading based on this does not become a difficult task.
