Description

Ring service method by subscriber group of exchange system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exchange system, and more particularly, to a method of classifying extension subscribers into groups and then serving rings corresponding to each group.

In general, the exchange system is configured as shown in Fig.

Referring to FIG. 1, the central processing unit 100 controls overall operation of the system, such as controlling call switching and providing various services to subscribers. The memory unit 102 stores programs and initial service data of the central processing unit 100 for performing basic calls and various functions and temporarily stores data processed by the central processing unit 100. [ The memory unit 102 includes a ROM for storing program and service data, and a RAM for temporarily storing data generated during program execution. The clock circuit 104 generates current time data as a clock chip IC and outputs it to the central processing unit 100. The switching circuit 106 switches various tones and voice data under the control of the central processing unit 100.

The general telephone set subscriber circuit 108 supplies the call currents to the general telephone sets A, B, C and D under the control of the central processing unit 100 and at the same time, 106). The ring generator 110 generates a ring signal and supplies it to the subscriber line. The digital telephone subscriber circuit 112 transmits and receives various data to and from a digital telephone set (E, F, G, H) under the control of the central processing unit 100, E, F, G, and H) and the switching circuit 106. Here, the digital telephones E, F, G, and H and the public telephones A, B, C, and D are extension subscribers. And the line connecting the ordinary telephone subscriber circuit 108 and the digital telephone subscriber circuit 112 to the extension subscriber becomes a subscriber line.

The tone generator 114 generates various tone signals under the control of the central processing unit 100 and outputs them to the switching circuit 106. The CO line circuit 116 seizes the CO line under the control of the central processing unit 100 to form a CO line loop and interfere signals between the CO line and the switching circuit 106. Here, the term " CO line " refers to a line connecting the CO line circuit 116 and the public switching center.

The DTMF receiver 118 analyzes the DTMF signal input from the switching circuit 106, converts the DTMF signal into digital data, and outputs the digital data to the central processing unit 100. Here, the DTMF signal received by the switching circuit 106 in the DTMF receiver 118 may be a telephone number generated by an external subscriber through a trunk line or a telephone number generated by an extension subscriber. The DTMF transmitter 120 converts the digital data output from the central processing unit 100 into a DTMF signal and outputs the DTMF signal to the switching circuit 106.

The exchange system configured as shown in FIG. 1 performs a function of serving a ring to a called party extension subscriber when a call is generated. At this time, the service ring is served regardless of the affiliation of the extension subscribers. Therefore, it is not easy to distinguish which telephone rings when a ring is generated in an office environment where a large number of extension subscribers live. That is, the ringing sound alone can not identify the subscriber being called. Therefore, there is a problem in that the efficiency of the work is lowered when the telephone of the other department having the person to receive the telephone is received. Also, there is a problem in that the quality of the telephone service is deteriorated due to the inability to respond to the call received from the user's own department.

It is therefore an object of the present invention to provide a method of servicing a ring that subscribers can distinguish in an exchange system.

It is another object of the present invention to provide a method for improving the efficiency of work which is degraded as subscribers receive calls from other departments in an exchange system.

Another object of the present invention is to provide a method for improving the quality of a telephone service which is degraded due to a failure of a subscriber to answer a telephone call to his / her department in an exchange system.

According to another aspect of the present invention, there is provided a method of classifying a plurality of extension subscribers using a digital telephone into groups and serving different types of rings for each group.

A ring service method according to the present invention includes a ring code allocation process of classifying a plurality of digital telephones into groups and allocating a ring code corresponding to each group, A code generation process, and a ring generation process for generating a ring corresponding to the generated ring code. The ring code generation process includes a first step of checking to which group a corresponding digital telephone belongs when a call is received, and a second step of generating a ring code indicating the checked group.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a detailed description of preferred embodiments of the present invention will be described with reference to the accompanying drawings.

In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

First, the present invention is applied to a digital switching system that connects a plurality of digital telephones connected to a digital telephone subscriber circuit 112 of the switching system shown in FIG. 1 to an extension subscriber. The operation of the present invention enables the digital phone to provide various ring tone sources. Most of the PABXs (Private Automatic Branch Exchanges) currently used have a function of bundling extension subscribers, This is because there is a so-called Grouping function.

In order to operate the ring service according to the present invention, it is first required to classify a plurality of digital telephones into groups. FIG. 2 is a diagram showing that a plurality of digital phones are classified into groups. ..., An form a group A, B1, B2, ..., Bn form a group B, and C1, C2, ..., Cn form a group C . In this case, it is desirable to classify the criteria of the classification into the departments performing the same tasks.

FIG. 3A is a diagram illustrating a structure of a subscriber table storing results of a plurality of digital telephones classified into groups as shown in FIG. 2. Referring to FIG. The subscriber table stores subscriber information and group information indicating the affiliation of the subscriber, as well as codes corresponding thereto. At this time, the codes are codes corresponding to each group. FIG. 3B is a diagram showing a structure of a ring table storing ring sources that can be generated by a digital telephone in association with codes. Referring to FIG. 3B, code A corresponds to A ring, code B corresponds to B ring, and code C corresponds to C ring.

When the subscriber table as shown in FIG. 3A is provided in the switching system and a ring table as shown in FIG. 3B is provided in the digital telephone, the ring service operation according to the present invention is performed.

4A and 4B are views illustrating a process flow of providing a ring service for each subscriber group according to the present invention.

If it is assumed that a call for calling an A1 digital telephone set belonging to the A group has occurred, the PBX will judge that a call has occurred in step S11. Next, in step S12, the private branch exchange examines the subscriber table as shown in FIG. 3A to determine which group the called party belongs to and what kind of code corresponds to the called group. As a result, the group A will be identified as the incoming group, and the A code will be verified. Then, the PABX generates the confirmed A code in step S13 and sends it to the A1 digital telephone set.

The A1 digital phone then confirms that the code is received in step S21. When the code is confirmed, the A1 digital phone checks the ring corresponding to the code received in the step S22 by using the ring table shown in FIG. 3B. At this time, the A ring will be confirmed. After confirming the ring, the A ring is confirmed in step S23. As a result, the subscriber of the A1 digital telephone can confirm the A ring distinguished from other rings.

As described above, the present invention provides a method of classifying a plurality of extension subscribers using a digital telephone into groups and serving different types of rings for each group. This has the advantage that subscribers can improve work efficiency, which is degraded as calls are received from other departments. In addition, there is an advantage that the quality of the telephone service which is deteriorated due to the failure of the subscribers to respond to the incoming call to the department of the subscriber can be improved.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
