Abstract

PURPOSE:To allow the subscriber contract information management system not to notify the change of an accommodation position of the subscriber by providing subscriber contract information of a stored program control exchange corresponding to a logical subscriber accommodation location called a normal ized number and revising the correspondence between the logical subscriber accommodation position and the subscriber accommodation position so as to absorb the deletion/reregistration of huge subscriber contract information. CONSTITUTION:Normalized numbers subjected to logic processing uniquely in an exchange for each subscriber accommodated in the exchange are generated and registered by a normalized number management table 1. An accommodate location/normalizing number table 2 makes the normalizing number correspond to the subscriber accommodated position. Subscriber contract information 4 stored in each subscriber is allocated by a pointer table 3 corresponding to the normalized number.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage program control type exchange data management system, and more particularly to a subscriber contract information management system.

[0002]

2. Description of the Related Art In conventional subscriber contract information management in an exchange, data is managed as data corresponding to a physical subscriber accommodation position. Therefore, every time the subscriber accommodation position is changed, the old subscriber accommodation position is dealt with. The enormous amount of subscriber contract information that was attached was deleted and re-registered for the new subscriber accommodation location.

[0003]

In this conventional subscriber contract information management system for an exchange, since the subscriber contract information is associated with the subscriber accommodation position, a huge number of subscriber contracts are required when changing the subscriber accommodation position. There is a problem that the information must be deleted from the old subscriber accommodation position and the subscriber contract information must be reassigned to the new subscriber accommodation position.

[0004]

The subscriber contract information management system of the present invention is a storage program control type exchange.
For each subscriber accommodated in this exchange, a normalization number that is uniquely logicalized in the exchange is generated and registered, the normalization number is made to correspond to the accommodation position of the subscriber, and stored for each subscriber. The subscriber contract information is allocated in correspondence with the normalized number.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings, separately for a case of newly establishing a subscriber and a case of changing accommodation.

FIGS. 1 (a) to 1 (c) are diagrams showing a data structure of an embodiment of the present invention, and FIG. 1 (a) is a diagram showing a table for managing a normalized number for logicalizing a subscriber accommodation position. ,
(B) is a figure which shows the accommodation position / normalization number table which shows the correspondence of an accommodation position and a normalization number, (c) is a figure which shows subscriber contract information management. The present invention is realized by a central control unit of a storage program control type exchange (not shown) writing and reading data shown in (a) to (c) provided in a storage device.

First, when a new subscriber is registered at the time of new installation, the normalized number management table 1 is searched, and a vacant normalized number is assigned to the new subscriber to store the accommodation position / normalized number table. The assigned normalization number is associated with the area of the new subscriber accommodation position of 2. After that, the area of the subscriber contract information 4 is allocated, the subscriber contract information pointer table 3 is generated, and writing is performed in the allocated area of the subscriber contract information 4.

Next, when the accommodation is changed, when the accommodation of the subscriber is changed using the old accommodation position and the new accommodation position as input information, first, the accommodation position / normalized number table 2 is searched at the old accommodation position. Then, the normalized number is calculated. Next, the normalization number is written in the area of the new accommodation position of the accommodation position / normalization number table 2, and the normalization number is deleted from the area of the old accommodation position.

[0009]

As described above, according to the present invention, by providing a normalized number which is a logicalized subscriber accommodation position, the subscriber contract information is given to the normalized number, and the subscriber accommodation information is separated from the subscriber accommodation position. This has the effect of eliminating the need to rewrite enormous amounts of subscriber contract information when changing the subscriber accommodation location.

Claims (1)

[Claims] 1. In a storage program control type exchange, for each subscriber accommodated in the exchange, a uniquely normalized normalization number is generated and registered in the exchange, and the subscriber is accommodated in the accommodating position. A subscriber contract information management system characterized in that normalization numbers are made to correspond and subscriber contract information stored for each subscriber is allocated in correspondence with the normalization numbers.
