JPS63302655A - Corresponding signal transmission method by audible voice among plural communication businessmen - Google Patents

Abstract

PURPOSE:To prevent duplex cache and to enlarge service in place of a corresponding signal by returning audible voice to origination communication business with respect to calls straddling plural communication business having their own networks in an incoming person responding time speech path. CONSTITUTION:A G station 1 is the barrier station of the existing communication business and a J station 2 is the station of novel communication business. When there is a call from respective subscribers 13 and 14 to a subscriber 21 and the call starts from the G station 1 to the J station 2, the J station 2 judges the presence and absence of the originator ID with respect to respective calls. As for the call from the subscriber 14 without the originator ID, 1,000 Hz audible tone is returned to the 500ms subscriber 14 through the answering time speech path of the subscriber 21. Thus, it is eliminated that the corresponding signal cannot be returned to the originator, and an object is attained.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to exchange software, and in particular, to exchange software between a new carrier and a carrier with an existing network, or between a new carrier and another carrier on the same territory. This relates to a response signal sending method that does not affect the

[Conventional technology]

The conventional response signal sending method is to put the response signal on top of the control signal and send it back to the previous station managed by another carrier, which then sends the response signal back to the previous station, and finally There is a method for returning a response signal from the terminal station to the originating terminal.

[Problem that the invention seeks to solve]

The feasibility of using the conventional response signal return method described above, when a call spans multiple carriers, depends on the system configuration of the originating carrier, especially if the caller has an existing network and system. For telecommunications carriers that use common lines, it is not always possible to distinguish between billing responses (ANC) and non-billing responses (ANN), and in this case, incoming communications services are unconditionally accepted. When the caller returns a response to the originating carrier, the originating carrier not only charges the access charge to the terminating carrier at the barrier station, but also charges the caller at the optical terminal station within its own network. In addition, if the response signal cannot be sent back to the caller, it becomes impossible to use a data terminal that activates upon receiving the response signal (reverse), and the relay There is a problem in that it imposes restrictions on the services of telecommunications carriers.

[Means for solving problems]

In order to solve these problems, the present invention provides an audible sound to be sent back to the originating carrier on the call path when the called party answers a call that spans multiple carriers that have their own network, thereby replacing the response signal. This is how it works.

[Effect]

The method of sending a response signal using an audible sound between multiple communication carriers according to the present invention replaces the response signal by sending an audible sound back to the caller for a certain period of time through a communication path.

〔Example〕

The method of sending a response signal using an audible sound between multiple carriers according to the present invention does not affect the carrier's system that manages the caller in any way, and the relay carrier's software when the receiving terminal responds During the process, an audible sound is sent back to the caller for a certain period of time through a communication path, thereby replacing the response signal. In this case, since the ringing tone (RING BACK TONB) is sent from the terminating station while the call is in progress, the communication path from the caller to the terminating station is established, and the audible response tone is reliably returned to the caller. be done. The caller also needs a piece of hardware to detect this audible response as an alternative to reversing.

Next, an example of a method for transmitting a response signal using an audible sound between multiple communication rates and operators according to the present invention will be explained using a diagram.
In the figure, station 0 1 is a gateway station of an existing carrier, stations No. 11 and 12 are terminal stations of the existing carrier, station 3 2 is a station of a new carrier, 13. 14
are respectively NO, N1 station 11, subscriber of 12, 21 is 3
As a subscriber of station 2, there is a distinction between an accounting response signal (ANC) and a non-accounting response signal (AN N) between stations 01 and 11, and this distinction between stations 01 and 12. Without,
This difference is caused by the caller ID (caller phone number) when starting up between stations.
This can be determined by saying that it is possible to send from 80 stations 11 to 0 stations 1, but it is not possible to send from N1 stations 12 to 0 stations 1. Therefore, when calls from subscribers 13 and 14 to subscriber 21 are initiated from station 0 1 to station 3 2, station 3 2 determines whether each call has a caller ID. For calls from subscriber 14 without caller ID, a 1000 Hz audible tone is transmitted for 500 ms through the answer waiting channel of subscriber 21.
It is sent back to subscriber 14.

〔Effect of the invention〕

As explained above, the present invention provides an audible sound to be used as a response signal by returning an audible sound to the originating carrier on the call path when the called party responds to a call that spans multiple carriers having their own network. It no longer becomes impossible to send a response signal back to the caller for a call, and data terminals that activate upon receiving a response signal can be connected through relay carriers, which has the effect of expanding services and making it easier for existing carriers to This also has the effect of preventing double billing among users.
