Abstract

The present invention relates to an outgoing call processing method of a private exchange that allows a private exchange to process a call as a called party of another station is provided. By handling the outgoing call in charge from the time of hooking off the handset to the process of hooking up after the end of the call, the call with each subscriber subscribed to another exchange is facilitated.

Description

How to handle outgoing call on private exchange

The present invention relates to an outgoing call processing method of a private exchange, and more particularly, to an outgoing call processing method of a private exchange that allows a call processing by calling a called party of a foreign country in the private exchange.

The present invention calls outgoing call in charge of the hook-on process after the end of the call from the time when the calling subscriber hooks off the handset to call the called party of the other country in the private exchange. The purpose of the present invention is to provide a method of handling outgoing call of a private exchange.

10,12,14: first, second, third access switching subsystem

16: I / O subsystem

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, an embodiment of the present invention for achieving the above object in detail.

1 is a block diagram showing an embodiment of a private exchange for applying the outgoing call processing method of a private exchange according to the present invention, wherein each of the first, second, and third access switching subsystems that is a basic unit system of the private exchange; (Access Switching Subsystem (ASS) 10, 12, 14) and an input / output subsystem (IOS) 16 for matching with a system operator.

An embodiment of a private exchange for applying the present invention made as described above will be described in detail with reference to FIG. 2.

First, each of the first, second, and third access switching subsystems 10, 12, and 14, which are the basic unit systems of the private exchange, has a matching function for accommodating the subscriber and the relay line, the signal from the subscriber, and the switching period signal processing. It provides subscriber circuit and line test function as well as function for switching function for communication and communication line.

Next, the input / output subsystem 16 for matching with the system operator is connected to each of the first, second, and third access switching subsystems 10, 12, and 14 by a redundant T-bus. Performs program loading, data back-up, storage and analysis functions of the second and third access switching subsystems 10, 12, and 14, and a man machine communication function with a system operator. To provide.

FIG. 2 is a flowchart illustrating an embodiment of a method for processing an outgoing call in a private exchange according to FIG. 1.

First, upon receiving a hook-off signal from an originating subscriber, information about the subscriber (for example, the rating and call restriction information of the subscriber) is analyzed to determine whether the call can be made, and a dial tone is generated for the originating call. The transmission, i.e., subscriber call processing, is processed (20).

Next, when the private exchange system is receiving a dial tone or a special dial tone or receiving a number from a subscriber, the number is received from the subscriber and analyzed to obtain various types of information on the called party and according to the analysis result. Or receive an outgoing call, i.e., receive and analyze subscriber numbers (22).

Subsequently, it decides whether to accept the call according to the calling party or the class of the route and the class of the called route, and determines the lane route and the bypass route according to the source and routing case, occupying the relay line and assigning the relay line signal as needed. It sends a digit to the counterpart exchange, that is, handles a relay line call (24).

Upon receiving the relay line response signal from the other exchange, the call state is changed to busy and charging is started, that is, the relay line response is processed (26).

In addition, when receiving the clearing signal of the called party in the busy state, it connects the ringing tone according to the release condition, stops charging, and terminates the call, i.e., the relay line backward cutting, upon receiving the outgoing subscriber recovery signal ( 28).

Next, when receiving the calling party disconnection signal in the busy state, it connects the ring tone according to the release condition, stops charging, and terminates the call when receiving the called party recovery signal or the called party recovery signal (30). ).

As described above, the present invention allows the originating subscriber to handle outgoing calls in charge of the hooking process from the time of hooking off the handset to the call of the called party of another country, from the end of the call to the process of hooking in the private exchange. There is an effect of facilitating a call with each subscriber subscribed to the exchange.

Claims (6)

A first step 20 of processing the subscriber call view, a second step 22 of processing receiving and analyzing subscriber numbers after performing the first step 20, and a relay line call after performing the second step 22 A third step (24) of processing a second step, a fourth step (26) of processing a relay line response after performing the third step (24), a second step of processing a relay line backward cutting after performing the fourth step (26). In outgoing call processing of a private exchange comprising a fifth step 28 and a sixth step 30 of processing outgoing subscriber truncation after performing the fifth step 28: When the first step 20 receives the hook-off signal from the calling subscriber, the first subscriber 20 analyzes the information on the subscriber to determine whether the call can be made, and transmits a dial tone for the call. How to handle outgoing call. The method of claim 1, In the second step 22, when receiving a number from a subscriber in a state of transmitting a dial tone or a special dial tone or receiving a number, the second step 22 analyzes the received number and obtains various kinds of information on the called party. Outgoing call processing method of a private exchange characterized in that it determines whether the internal call or outgoing call. The method of claim 1, The third step 24 determines whether to accept the call according to the class of the calling subscriber or the route and the class of the called route, and determines the lane route and the bypass route according to the source and routing case, and occupies the relay line and needs it. And assigning a relay line signal according to the method, and transmitting a digit to a counterpart exchange. The method of claim 1, The fourth step (26) is the outgoing call processing method of the private exchange, characterized in that when receiving a relay line response signal from the other exchange to change the state of the call to busy. The method of claim 1, The fifth step 28 is characterized in that when receiving a called party clearing signal in the busy state, it connects a ring tone according to the release condition, stops charging, and terminates the call when receiving the outgoing subscriber recovery signal. Outgoing call processing method of a private exchange. The method of claim 1, The sixth step 30 is characterized in that when receiving a calling party disconnect signal in a busy state, the call is connected according to a release condition, the billing is stopped, and the call is terminated when a called party recovery signal or a called party recovery signal is received.
