Abstract

PURPOSE: A method for providing a receiver discrimination service in a switch is provided to discriminate a receiver by only bell sound using one directory line without a new directory line by designating a plurality of inter-different directory numbers to one directory line and designating a ring signal with an inter-different type corresponding to each directory number. CONSTITUTION: A plurality of inter-different directory numbers are designated in one directory line assigned in a corresponding subscriber according to a receiver discrimination service entrance request(S10). A ring signal with an inter-different type is designated in each designated directory number(S12). If a calling subscriber hooks off a telephone, a switch transmits assigns an idle resource and transmits a calling sound to the calling subscriber(S14). The switch receives a called digit from the calling subscriber(S16), and starts a number translation using the received called digit(S18). If a called occupation is requested to a called subscriber according to the translation, a state of a corresponding called subscriber is confirmed and it is judged whether an incoming is performed(S20). If the incoming is not performed, a tone according to a state of a called subscriber is transmitted to the calling subscriber(S22). If the incoming is performed, it is judged whether a corresponding called subscriber is a receiver discrimination service subscriber(S24). If the corresponding called subscriber is the receiver discrimination service subscriber, a corresponding directory number is analyzed and a ring signal assigned in the corresponding directory number is transmitted to the called subscriber(S28).

Description

Method for recipient distinctive service providing in switching system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for providing a receiver distinguishing service at an exchange, and more particularly, to a method for providing a receiver distinguishing service in an exchange that enables a receiver to distinguish a receiver by using only a ringing sound when a plurality of people commonly use a limited telephone.

Generally, a directory number is used when a called subscriber is to be called by a telephone subscriber number in the same exchange corresponding to a machine number, and the calling subscriber can dial the subscriber number to call the called subscriber.

Conventionally, subscriber numbers used when calling a called subscriber are assigned to each called subscriber one by one, and these subscriber numbers are assigned one-to-one to one subscriber line connected to the called subscriber terminal. And only one ring type calling the called party is specified in the subscriber line.

Therefore, the assigned subscriber line is limited, such as a general home or office, and when there are a large number of people using a limited called subscriber terminal, it is impossible to know who the call is from by only the ring tone provided by one ring type. After answering the call, you will know who the recipient is.

As described above, in the conventional exchange, since only one subscriber number is assigned to one subscriber line and only one ring type is provided, a bell that always sounds the same when multiple people use a limited telephone in common There is a problem that can not identify the receiver only by sound.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and in the case where a large number of people use a limited telephone in common, a plurality of different subscriber numbers are assigned to one subscriber line at an exchange, and each designated subscriber number is assigned. It is an object of the present invention to provide a method for providing a receiver distinguishing service in an exchange that enables a receiver to distinguish a receiver using only one ringing line without adding a new subscriber line by designating different types of ring signals correspondingly.

1 is a diagram illustrating a structure of a subscriber number and ring signal table configured to implement a method for providing a receiver distinguished service in an exchange according to the present invention;

2 is an exemplary view showing a ring signal used to implement a method for providing a receiver discrimination service in an exchange according to the present invention.

3 is a view for explaining a method for providing a receiver distinguished service in an exchange according to the present invention.

In order to achieve the above object, there is provided a method for providing a receiver distinguishing service in an exchange according to the present invention, comprising: assigning a plurality of different subscriber numbers to a corresponding subscriber line; Designating different ring signals corresponding to each of the subscriber numbers; Receiving the subscriber number from the calling subscriber comprises a receiver distinguishing service process for transmitting the ring signal specified in the subscriber number to the called subscriber.

The recipient distinguishing service process may include receiving a subscriber number from the calling subscriber and translating the received subscriber number; Determining whether the incoming call is possible by checking the state of the called party according to the number translation; Determining that the called subscriber is a recipient distinguished service subscriber if the incoming call is possible; And if the called subscriber is a recipient distinguished service subscriber, transmitting the ring signal specified in the received subscriber number to the called subscriber.

If the called subscriber is not the recipient distinguished service subscriber, the method further includes transmitting a general ring signal to the called subscriber.

Hereinafter, with reference to the accompanying drawings will be described in detail a method for providing a service for distinguishing recipients in an exchange according to a preferred embodiment of the present invention.

In order to implement a method for providing a receiver distinguished service in an exchange according to the present invention, first, a subscriber must receive an application for receiving a receiver distinguished service from a subscriber, and the operating station that receives the service request provides a receiver distinguished service by MMC (Man Machine Communication) operation. It registers subscribers to receive and sets various functions necessary to provide distinguished services.

As described above, in order to provide the recipient distinguished service, functions necessary for providing the recipient distinguished service are set. There are two methods for setting the function depending on the subscriber who has received the service request.

In the first case, the existing subscriber has applied for the recipient discrimination service. In this case, the subscriber number specified in the existing subscriber line is set as the representative number. The above-mentioned representative number becomes identification number 1, and the subscriber identification service subscriber registration is performed using this representative number.

As described above, the subscriber number generated after the representative number is set becomes the next identification number 2, identification number 3, identification number 4, and the like in the generation order. Here, the identification number can be deleted arbitrarily, but the representative number can be deleted only after all other identification numbers have been deleted, and the subscriber identification service subscriber registration can be performed only for the representative number. And, the subscriber distinguishing service subscriber registration cancellation can also be executed only for the representative number, and the recipient discrimination service subscriber registration cancellation can be executed after all other identification numbers are deleted.

As described above, a different type of ring signal corresponding to each subscriber number is assigned to a subscriber number designated corresponding to each identification number, and when a calling party calls an arbitrary subscriber number, a called party can be identified. So that it rings with the ring signal assigned to that subscriber number.

In the second case, a new subscriber number is applied to a receiving subscriber when the new subscriber applies for subscription to the management station. In this case, a new subscriber number is allocated to a new subscriber line. It is set as the representative number. As described above, when the representative number is set, the representative number becomes identification number 1, and the subscriber identification service subscriber registration is performed by using the representative number.

As described above, the subscriber number generated after the representative number is set becomes the next identification number 2, identification number 3, identification number 4, etc. according to the generation order, and each subscriber is assigned to the subscriber number designated corresponding to each identification number. Different types of ring signals corresponding to the numbers are designated, and when the calling party dials an arbitrary subscriber number, the ringer is ringed by the ring signal assigned to the corresponding subscriber number to distinguish the called party.

1 is a road showing the structure of a subscriber number and a ring signal table configured to implement a method for providing a receiver distinguished service in an exchange according to the present invention, and (a) represents a number assigned to each subscriber line connected to a subscriber station. A line number table, (b) an identification number table indicating an identification number assigned to each subscriber line, (c) a subscriber number indicating a subscriber number assigned to each identification number and a ring signal assigned to that subscriber number; Ring signal table.

FIG. 2 is an exemplary view showing a ring signal used to implement a method for providing a receiver discrimination service in an exchange according to the present invention, in which there are a plurality of identification numbers assigned to each subscriber line, and corresponding to each identification number. There is a subscriber number, and different ring signals are designated corresponding to each subscriber number.

3 is a view for explaining a method for providing a receiver distinguished service in an exchange according to the present invention.

First, a plurality of different subscriber numbers are assigned to one subscriber line assigned to the corresponding subscriber according to the receiver discrimination service subscription request (S10). Thereafter, a different type of ring signal is assigned to each subscriber number specified in step S (S12). As described above in step S10, a plurality of different subscriber numbers are assigned to one subscriber line. In the embodiment of the present invention, four different subscriber numbers are designated.

As described above, after all the data necessary for providing the distinguishing service according to the request for subscribing to the distinguishing service is set through the process S10 and the process S12, the distinguishing service is provided to the subscriber.

That is, when the calling subscriber picks up the phone to try to call (Hook Off), the exchange allocates idle resources and sends out a dial tone to the calling subscriber (S14). In this way, when the dial tone is sent from the exchange, the calling subscriber hears the dial tone and dials the subscriber number of the called subscriber to call the called subscriber.

Accordingly, the exchange receives a predetermined number of incoming digits from the calling subscriber (S16), and starts number translation using the collected incoming digits (S18).

Subsequently, a call occupancy request is made to the called subscriber according to the number translation, and the state of the called subscriber is checked to determine whether the incoming call is possible (S20).

If the called party side is not in a state where the called party can receive the call as a result of the determination of step S20, a call tone is sent to the calling subscriber according to the state of the called party. If the called party is busy, the call indicating that the called party is busy A heavy signal tone is transmitted to the calling subscriber, and if the malfunction is being repaired, an announcement broadcast notifying that the failure is being repaired is transmitted to the calling subscriber (S22).

On the other hand, when the receiving subscriber side is in a state that can be received as a result of the determination of the above step S20 it is determined whether the receiving subscriber is the recipient distinguished service subscriber (S24).

If the called party is not the recipient distinguished service subscriber as a result of the determination of step S24, a general ring signal is sent to the called party (S26), and if the called party is the recipient distinguished service subscriber, the corresponding subscriber number is analyzed and the corresponding subscriber number is analyzed. The ring signal assigned to the subscriber number is transmitted to the called subscriber (S28).

In the switch according to the present invention, a method for providing a service for distinguishing between recipients is not limited to the above-described embodiment, and various modifications can be made within the scope of the technical idea of the present invention.

According to the method of providing a receiver distinguishing service in the exchange according to the present invention as described above, a plurality of different subscriber numbers are assigned to one subscriber line at the exchange, and a different type of ring signal is assigned in correspondence with each designated subscriber number. As a result, the receiver can be distinguished by a ring tone using only one subscriber line without adding a new subscriber line, so that it is possible to know who the call is from without receiving a call.
