Abstract

PURPOSE:To reduce the amount of traffic in a network by registering the station identification information of a destination when a subscriber moves to another network, transferring a call to the subscriber to a destination station at the time of connection, and simultaneously, registering the station identification information of the destination on a caller housing station. CONSTITUTION:When the subscriber registers affiliation at the exchange 3, a station transfer registration part 32 registers destination station identification information on the subscriber number table 1a of the former housing station 1 of the subscriber in the case of transfer from another station. Following that, when an incoming call arrives at the exchange 1, a subscriber number developing part 11 retrieves the subscriber number table 1a, and when the subscriber is moving to another station, a call is transferred to a subscriber housing station by a transfer processing part 12, and also, the destination station identification information is registered on the subscriber number table 2a of an outgoing station 2 by a station transfer registration part 13. Hereafter, it is possible to perform outgoing and connection directly to the exchange 1 when a callee number is dialed again at the exchange 2. In such a way, the amount of traffic in an exchange network can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a subscriber number management device for a switching network.

[Conventional technology]

Conventionally, in this type of subscriber number management system, the subscriber number was composed of an exchange number and an extension number.

[Problem to be solved by the invention]

In the conventional subscriber number management system described above, the subscriber number is in the form of an exchange number and an extension number, so there is a drawback that when a subscriber moves from one network to another, the destination number changes.

An object of the present invention is to provide a subscriber number management device that solves the aX problem.

[Means to solve the problem]

In order to achieve the above object, a subscriber number management device according to the present invention provides a method for moving a subscriber telephone to a previous switching center when moving the subscriber telephone from the switching center where it is currently accommodated to another switching center in a switching network. A means for registering destination switching center identification information, and a means for registering destination switching center identification information to the caller receiving center at the same time as transferring the call to the moving destination switching center when the calling party dials the destination before movement by the calling side telephone. and means for registering.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a functional block diagram showing one embodiment of the present invention. In FIG. 0, 1 is a subscriber telephone (hereinafter referred to as a subscriber telephone).

2 is the calling station, and 3 is the last month in which the subscriber's telephone set (hereinafter referred to as the subscriber) was moved. 11 is a subscriber number development section, 12 is a transfer processing section, 13 is a station movement registration section, 31 is a subscription registration processing section, and 32 is a station movement registration section. Also, la, 2a, and 3a are subscriber number tables.

In the figure, when a subscriber performs subscription registration at the exchange 3, the subscription registration processing unit 31 registers accommodation location information in the corresponding area of the subscriber number table 3a, and determines whether the subscriber is moving from another station. . Another station?

In the case of movement, the one-station movement registration unit 32 registers the destination station identification information in the subscriber number table 1a of the subscriber's original accommodating station 1. Subsequently, when a call arrives at the exchange 1, the subscriber number expansion section 11 searches the subscriber number table la, and if the call is being transferred to another station, the transfer processing section 12 transfers the call to the subscriber accommodation station 1. At the same time, the station movement registration unit 13 registers the destination station identification information in the subscriber number table 2a of the calling station 2.

It is clear that if the called party number is dialed again at the exchange 2 thereafter, a direct outgoing connection to the exchange 1 can be made. This sequence is shown in Figure 2 (b).

Shown in (c). FIG. 2(a) shows the process during movement, (b) shows the first call process, and (c) shows the second and subsequent call processes.

〔Effect of the invention〕

As explained above, when a subscriber moves through the network, the subscriber registers the destination station identification information, transfers the call to the destination station at the time of connection, and at the same time informs the caller accommodation station of the destination station. Since the station identification information is registered, subsequent connections are made directly to the previous month, which has the effect of reducing traffic within the network.
