Abstract

PURPOSE:To attain the transit of subscriber between plural exchange units while keeping the same number to the subscriber respectively. CONSTITUTION:Unit number information representing a subscriber accommodated in its own unit accommodated to an exchange 1 and representing a subscriber accommodated in other unit accommodated in other exchange 10 in plural units and path selection information representing a path to the exchange when the unit number information indicates that the subscriber is accommodated to the other unit are set to transit object subscriber data 6 of the exchange 1. At the arrival of a call to the transit object subscriber, the exchange 1 refers to the unit number information and when the subscriber is accommodated in its own unit, its own station incoming call connection is implemented to the subscriber. In the case of the accommodation to other unit, the exchange 1 decides an outgoing path according to the path selection information to attain relay connection to the exchange 10. Its own station incoming call connection to the transit subscriber is implemented by the exchange 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subscriber accommodation replacement control system used for a subscriber switching between units in a station of a plurality of exchange units.

[0002]

2. Description of the Related Art In a conventional exchange, one local area code belongs to one subscriber level exchange, and a plurality of exchanges cannot accommodate subscribers with the same area number. Therefore, in the conventional method, at the time of relocation of subscribers across exchanges,
It is not possible to transfer with the same subscriber number, and it is necessary to newly change the number to the station number managed by the transfer destination exchange. In addition, when relocating on a station-by-station basis, it is possible to switch all subscribers simultaneously by station number.

[0003]

In the above-mentioned conventional subscriber accommodation replacement control system, since the subscribers are switched all at once in the exchange unit or in the station number unit, the same number across the exchange units in one subscriber unit is used. However, there is a drawback in that the change of the subscriber number cannot be performed and the subscriber number is changed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a subscriber accommodation replacement control system that enables the migration of subscribers in a plurality of exchange units with the same number.

[0005]

SUMMARY OF THE INVENTION A subscriber accommodation replacement control system of the present invention is a subscriber between a plurality of exchange units for migrating a subscriber accommodated in a storage program controlled first exchange to a second exchange. In the accommodation change control method,
In the subscriber data of the subscriber to be transferred to the first exchange,
Unit number information indicating whether the subscriber accommodates the own unit accommodated in the first exchange or accommodates another unit accommodated in the second exchange, and this unit number information indicates accommodation of the other unit. At this time, route selection information indicating a route to the corresponding exchange is provided, and when the transfer target subscriber receives a call, the first exchange refers to the unit number information. The incoming connection is made to the transfer target subscriber, and in the case of accommodation of another unit, the relay connection to the second exchange is made according to the route selection information, and the second exchange makes an incoming connection to the moved subscriber. It is a configuration to be performed.

[0006]

The present invention will be described below with reference to the drawings.

FIG. 1 (a) is a block diagram showing an embodiment of the present invention, and FIG. 1 (b) is a flow chart showing the processing flow of an embodiment of the present invention.

1A and 1B, an exchange 1 is a subscriber accommodation exchange connected to a subscriber terminal 8, another exchange 9 and another exchange 10 in a plurality of exchange units, and a connection control unit 2 The number translation unit 3, the number translation data 4, the subscriber translation unit 5, the subscriber data 6, and the connection processing unit 7 are included.

The subscriber data 6 includes unit number information indicating whether the subscriber to be transferred is accommodated in the own unit accommodated in the exchange 1 or accommodated in another unit accommodated in the exchange 10, and this unit number information. Indicates that the other unit is accommodated, the route selection information indicating the route to the corresponding exchange is set.

The connection control unit 2 receives a connection request from the subscriber terminal 8 or another exchange 9, and determines an exchange connection operation (task) based on the translation results of the number translation unit 3 and the subscriber translation unit 5. To do. The connection processing unit 7 executes the exchange connection process (task) determined by the connection control unit 2.

The number translation unit 3 translates the received dialing information with the number translation data 4 based on the request from the connection control unit 2, so that the station number of the station accommodated by itself (lost station) or the station number of another station accommodated (lost station). I will send back the result.

The subscriber translation unit 5 that translates the unit number of the subscriber, which is stored and stored in the subscriber data 6 and is connected, and outputs the outgoing route for the corresponding exchange, requests the connection control unit 2. By translating the subscriber data 6 based on the above, it is determined whether the subscriber is a subscriber accommodated in the own station (incoming of the own unit) or a subscriber accommodated in another station (incoming of the other unit), as shown in FIG. 1 (b). If it is a subscriber accommodated in another station, the unit number stored in the subscriber data 6 is returned.

When the result of the translation of the number is dropped, the connection control unit 2 determines the normal incoming call processing of the incoming call of its own unit based on the translation result of the subscriber. It is passed to the translation unit 3 and outgoing route selection is performed. In this case, the other station incoming call processing to reach the subscriber terminal 11 is determined.

FIG. 2 is a block diagram showing an example of a switching system for explaining an embodiment of the present invention.
4 and the subscriber 25 have the same subscriber number, and the case is shown in which the transfer is performed from the subscriber switch 21 of the transfer source to the subscriber switch 22 of the transfer destination by the same number.

Before the transition, the subscriber 24 is the subscriber exchange 21
Since it is managed by the incoming call to its own unit, the transit switch 20
When a request for connection to the subscriber exchange 21 is issued, the subscriber exchange 21 performs the incoming call processing of its own station to connect to the subscriber 4.

When the subscriber 24 makes a transition to the subscriber exchange 22 with the same number, the transition-source subscriber exchange 21 registers the subscriber 24 in the subscriber data as a subscriber of another unit and makes a transition to the destination. By registering the subscriber 25 as the own unit receiving subscriber, the subscriber exchange 22 of the above relays the connection request from the relay exchange 20 to the subscriber 24 to the destination exchange 22 by relaying from the source exchange 21. The above-mentioned exchange 22 performs the incoming call processing of its own station and connects to the subscriber 25.

[0017]

As described above, the present invention accommodates the subscribers who have the same subscriber number across the units in the stations of a plurality of exchange units. Since the unit number is registered and stored, and when the corresponding subscriber number arrives, it is configured to identify and connect to the own unit call or other unit call based on the unit number of the accommodation exchange in this subscriber data. When subscriber migration work is required due to station replacement, division, etc., it is possible to relocate subscribers across the stations with the same number so that the subscriber can continue to use the same number, and business For subscribers, the subscriber transfer work can be carried out not on a station-by-station basis but on an arbitrary subscriber unit basis, which has the effect of enabling high-safety and quick switching.
