JPH02119363A - Speech path control system - Google Patents

Abstract

PURPOSE:To rapidly respond to emergency or the absence of a maintenance engineer by enabling direct speech path control to be perform ed without interposing the maintenance engineer by dialing a specific number by a subscriber. CONSTITUTION:The constituent HOME of a speech path control information table represents a speech path before change, and the DIV represents the speech path to be changed after the dial of the specific number, and the constituent R represents whether or not the function is valid for the subscriber, respectively. When the subscriber who belongs to a subscriber group (i) dials the specific number for speech path control, the constituent R of the speech path control information storage table for subscriber is checked, and when the R is valid, a system is set at a state in performing speech path control. When a call to select a speech path A is generated under the state, the call automatically selects a speech path B.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic switching system using a storage program control method, and more particularly to a communication path control method.

[Prior Art] In a conventional electronic switching system, a call path is determined according to call path information set by a maintenance person, but the call path cannot be directly controlled from the subscriber side.

[Problems to be Solved by the Invention] The above-mentioned conventional call route control system has a problem in that there is no means for the subscriber to directly control the call route when it becomes necessary to change the call route due to the subscriber's convenience. , the subscriber must notify the maintenance person and change the call path control information.
There is a drawback that response may be delayed in case of emergency or when maintenance personnel are absent.

[Means for Solving the Problems] The call route control system of the present invention includes a storage means for storing call route control information exclusive to a subscriber, and a storage means that is accessed and stored by the subscriber's special number dial. It has means for controlling the communication path according to the control information.

[Function] The present invention sets in advance information on the communication path to be changed in the storage means for a subscriber whose communication path is considered to need to be controlled, and when the subscriber dials a special number, the information on the communication path to be changed is set in the storage means. This method realizes direct call route control from the subscriber by controlling the call route according to the call route information in the subscriber.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the structure of a communication path control information table used in the present invention, in which communication path control information is stored. The component HOME of this table is the call path before change, DIV
indicates the call path that is changed after the special number is dialed, and component R indicates whether or not this function is valid for the subscriber. Moreover, the index N of this table is the subscriber group number to which the subscriber belongs, and it is also possible to have one-to-one correspondence with the subscriber. It is assumed that this table has been set in advance by the maintainer.

FIG. 2 is a diagram showing an example of changing from communication path A to communication path B. In the state shown in this figure, when a subscriber belonging to subscriber group i dials a special number for call route control,
The process follows the procedure shown in FIG. 3 by checking the component R of the subscriber channel control information storage table, and if R is valid, the system is placed in the channel control information state. Under these conditions, if a call that selects communication path A occurs, the call automatically selects communication path B according to the procedure shown in FIG.

In this example, two special numbers are prepared for use, one for registration and one for deletion, but in reality, by increasing the number of special numbers, a larger number of call paths can be registered. FIG. 5 shows an example in which there are four special numbers.

HOM E C Call path before change, DIVI, DIV2, D
IV3 is a changed communication path, and in this case, an example in which communication path A is changed to communication paths B, C, and D is shown. When special number 1 is dialed, the communication path is changed to communication path B, when special number 2 is dialed, communication path C9 is changed, and when special number 3 is dialed, communication path is changed to communication path C. Note that special number 4 is for deletion.

[Effects of the Invention] As explained above, the present invention enables the subscriber to directly control the call path by dialing a special number without going through a maintenance person. It has the effect of being able to respond quickly.
