The present invention relates to a method of connecting a ringing tone in software when processing a local call in an electronic switching system of the present invention.

In general, in the conventional electronic switchboard, the ring tone is connected at the calling party, so there is no way to find out whether the call path is correctly connected before the call. In general, call processing software shows that the call path of the incoming call is connected, but hardware may be disconnected. Therefore, there was a problem that a call tone could be heard at the calling party, but the incoming and outgoing call could occur and the exchange completion rate of the exchange could be greatly reduced.

Accordingly, an object of the present invention is to solve the problems of the prior art, to select the ring tone from the tone source (Tone Source) of the called party is determined, the call is sent to the calling subscriber through the call path connected to the calling subscriber During the process, it provides a method of connecting a call to verify that the channel is securely connected.

In order to achieve the above object, the present invention provides an Access Switching Subsystem (hereinafter referred to as ASS), an Access Switching Processor (hereinafter referred to as ASP) embedded in the originating ASS, and A source time switch processor (hereinafter referred to as a TSP), an internal connection network subsystem (hereinafter referred to as an INS) connected to the originating ASS, and an internal connection network processor (Interconnection) built in the INS; Network Processor (hereinafter referred to as INP) and Number Translation Processor (hereinafter referred to as NTP), Incoming ASS connected to the INS, Incoming ASP and TSP embedded in the Incoming ASS, A call tone connection method applied to an electronic switch having a calling tone source and a calling tone source connected to a calling TSP and a called TSP, respectively, the calling AS If a subscriber subscribed to S raises his / her handset, it checks whether the originating ASP is able to make a call and receives a digit if the subscriber is capable of making a call, and if the subscriber cannot make a call, the call is sent to the calling subscriber without processing the call. After performing the first step of performing the impossible tone and performing the first step, the number of digits received from the originating ASP is collected and the number translation request is requested to the NTP. And the second step of requesting connection to the calling party at the same time and performing a space switch connection notification, and after performing the second step, the called party ASS connects the calling party to the calling party and connects the ringing tone to the called party TSP. After performing the third step and the third step, the call tone from the called party's tone source is heard to the calling subscriber through the time switch. And a fourth step of giving a ring to the called subscriber of the ASS and terminating it.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a hardware configuration diagram to which the present invention is applied. In the drawing, reference numeral 1 denotes an access switching subsystem (ASS), and reference numeral 2 denotes an access switching processor (AP). (3) denotes an originating time switch processor (hereinafter referred to as TSP), (4) denotes an interconnection network subsystem (INS), and (5) denotes an internal interconnection network processor; (6) is called Number Translation Processor (hereinafter referred to as NTP), (7) is called ASS, (8) is called ASP, (9) is called TSP, and (10) is called An incoming tone source that stores a tone type (hereinafter referred to as a tone source) necessary for call processing at the exchange, and (11) is a source tone source.

The software required for call processing loads the ASP into Analog Subscriber Control (ASC), Traffic Control (TCO), and Local Service Control (LSC). The TSP is loaded with software for managing a time switch (hereinafter referred to as TSW).

2 is an overall flowchart of the present invention.

When a subscriber subscribed to the originating ASS (1) picks up the handset (11), it checks whether the ASC loaded in the originating ASP (2) is a subscriber capable of originating (12), If a subscriber who cannot make an outgoing attempt attempts to send a call to the TCO (13), the caller sends a tone to the calling subscriber without performing call processing (24). The TCO collects the received digits (14) and requests the number translation to the NTP (6) (15). The incoming call occupancy request is made to the ASC of the incoming ASP 8 determined by the NTR of the NTP 6 (16), the called subscriber is determined (17), and the space switch of the originating and incoming calls determined in the TCO of the originating ASP (2) ( Space Switch (18), and requests to connect to the calling party to the calling ASC (19). At the same time, a space switch connection notification is provided. The incoming ASC of the called ASS 7 connects the called party's call path (20) and makes a call tone connection request to the called party's LSC.

Then, the called party LSC makes a call tone connection request to the TSW of the called TSP 9 (21). Then, the ring tone from the called party tone source 10 is transmitted to the calling party of the calling party 3 through the space switch of the INS 4 through the calling party calling party of the called ASP 8. The caller hears a ringing tone to the calling subscriber through a time switch (22). At the same time, a ring is given to the called subscriber of the called ASS (23).

Therefore, the present invention carried out by the above-described processing procedure can minimize the failure rate of the generated call, thereby improving the reliability of the exchanger.
