Abstract

The present invention relates to a time-out control method between digit inputs of a private exchange. After receiving a hook-off signal and a dialing signal for a called number from a calling terminal, the first digit number is received and then time counted. When the second elapses, an announcement for the time-out is sent to the calling terminal, and when 8 to 9 seconds do not pass, it is determined whether 5 to 6 seconds has elapsed, and when 5 to 6 seconds elapses, a specific prompt to enter the next digit number is promptly specified. A tone is sent to the calling terminal, the next digit number and the last digit number are received from the calling terminal that has received the specific sound to input the next digit number, and then the ring back tone is sent to the calling terminal, and the ring tone is used as the called terminal. As the calling / receiving terminal is connected, the caller does not dial from the beginning because it prevents timeout due to digit input. There is also an effect.

How to control timeout between digit inputs in a private exchange

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private exchange, and more particularly, to a method of controlling time out between digit inputs of a private exchange that can suppress a time out between a directory number input of a called subscriber.

In general, a private exchange is an international standard exchange that provides a relay exchange function of a public switched telephone network, and provides various exchange functions and services in various network types such as a comprehensive information communication network and an intelligent network.

In addition, the system type of the private exchange may be classified into a maximum of 16 customer group types for processing and operating individual customer group data and a system type for operation and maintenance of the customer group.

In the process of inputting the directory number of the called subscriber of the conventional private exchange, after entering one or several directory numbers, if the next digit is not input within 8 to 9 seconds, the announcement for the timeout is transmitted.

Accordingly, there is a problem in that the calling terminal has an inefficient inconvenience of receiving a guide broadcast for the timeout, and then redialing by hooking on its own handset and then hooking off again.

The present invention has been made to solve this problem, and its object is to prevent the timeout between digit inputs in the process of receiving a digit signal from the calling terminal. The present invention provides a method of controlling timeout between digit inputs of a private exchange so that a specific sound to be input can be transmitted.

The present invention for achieving the object relates to a time-out control method between the digit input of the private exchange, comprising the steps of receiving a hook-off signal from the originating terminal; And after the hook-off signal, a dialing signal for the called party directory number is received, after receiving the first digit number of the called party directory number, time counting; When 8 to 9 seconds have elapsed in time counting, transmitting an announcement for a time out to a calling terminal; If 8 to 9 seconds have not elapsed in time counting, next, determining whether 5 to 6 seconds have elapsed, and when 5 to 6 seconds have elapsed, transmitting a specific sound to promptly input the next digit number to the calling terminal; Sending a ring back tone to the calling terminal after sending the next digit number and the last digit number from the calling terminal which has received a specific sound to input the next digit number, and sending the ring tone to the called terminal; Preventing timeout between digit inputs by dialing, so that the caller / called terminal is connected.

Hereinafter, the objects and features of the present invention will be described in more detail with reference to the accompanying drawings so that the objects and features of the present invention can be more clearly understood.

FIG. 1 is a block diagram illustrating an overall time-out control method between digit inputs of a private exchange according to an embodiment of the present invention. The line processor 10 is abbreviated as Line Processor 10 and a line control subsystem. 12, a main processor (hereinafter abbreviated as MP) 20, a private line subsystem (hereinafter, abbreviated as PLS) 22, Number Translation (hereinafter abbreviated as NTR) 24, Subscriber Data Handling (hereinafter abbreviated as SDH) 26, and Input Output Processor (hereinafter referred to as IOP). Abbreviated).

The LP 10 is a line processor internally including the LCS 12. The LP 10 monitors the state of each line, reports the state to the MP 20, receives the control command of the MP 20, and receives each line. Peripheral device that performs the function of controlling.

The LCS 12 is a line control service system block included in a line processor. The LCS 12 detects a hook off / hook on signal transmitted from a calling terminal, detects a hook off signal, and then transmits the signal. The digit pulse signal according to the dial key input is received and transmitted to the PLS 22 in the MP 20.

The main processor includes a PLS 22, an NTR 24, and an SDH 26, and performs relay call processing with an originating terminal connected to the LCS 12 in the LP 10, and the originating terminal. It is an upper processor that performs a maintenance function for state management of various data transmitted from the system.

Among them, the PLS 22 is a private line subsystem block, which is connected to the LCS 12 belonging to the line processor, performs local call control with the originating terminal, outgoing call control, incoming call control, and billing information. Generate and collect statistical data and send it to NTR 24.

Here, the local call control is a series of call control procedures in which a calling party using a calling terminal calls a called party of its own country. Call origination, dial tone transmission, digital transmission, digital analysis, call routing, call signal transmission, and call routing Call proceeds in the order of connection and recovery.

And outgoing call control is a series of call control procedures in which an outgoing subscriber using a calling terminal calls a called party of another country, and incoming call control is a process in which a subscriber of another country calls a called party of its own country through its own incoming line. It is a series of call control processes.

The NTR 24 is a number translation block, which analyzes telephone number information on the called subscriber transmitted from the calling terminal, checks the use and called position, and retransmits it back to the PLS 22.

The NTR 24 also determines the destination and destination of the extension number information by determining the final destination from the device number and dial digit information of the line or the trunk line to the subscriber line or the trunk line by extension number translation and destination number translation. After performing the function, the PLS 22 is notified again of the result.

The SDH 26 is a subscriber data handling block. The SDH 26 receives an input for generating, changing, and canceling information about timeout control between digit inputs transmitted from the IOP 30 and then performing the processing for the PLS 22. ) To NTR 24.

The IOP 30 is an input / output processor that is in charge of controlling an input / output port for matching with an operator (not shown). The message data handling performs an analysis and management function of messages input and output through the input / output port. Input / output process management to perform state management and input / output control functions for each input / output port, and disk handling to perform file management functions for the hard disk in the IOP 30 PC; It consists of Data Generation, which generates the station data of the system and matches with the system software, and Data Extraction, which extracts the station data from the system package in operation. Connected to the SDH 26 in the main processor and between the digit inputs using the MMC connected to the IOP 30. Control information to prevent being out of register with the SDH (26).

The overall block diagram of the method for controlling timeout between digit inputs of a private exchange according to the present invention configured as described above has been described. FIG. 2 is a detailed flowchart of the present invention for a method of controlling timeout between digit inputs of a private exchange. Explain.

First, the LCS 12 in the LP 10 receiving the hook off signal from the originating terminal transmits the hook off signal to the PLS 22 in the MP 20 (step 200).

The PLS 22 receives the dialing signal for the called party directory number after the hook off signal (201). After receiving the first digit number of the called party directory number (202), the time is counted.

It is judged whether 8 to 9 seconds have elapsed in time counting (step 203), and when 8 to 9 seconds has elapsed, timeout occurs, and an announcement broadcast for time out is sent (step 204).

Since the dial input timeout has been reached, the hook-on signal is received from the calling terminal, and the hook-off signal is received in order to redial immediately, and then it is executed again from step 200 (step 205).

If 8 to 9 seconds have not elapsed in time counting, then it is determined whether 5 to 6 seconds have elapsed (step 206), and if 5 to 6 seconds has not elapsed, step 203 is executed.

When 5 to 6 seconds have elapsed, a specific sound for prompt entry of the next digit number is sent to the transmitter / receiver of the calling terminal (step 207).

After receiving the next digit number from the calling terminal which has received a specific tone to input the next digit number (step 208), the time is counted.

It is judged whether 8 to 9 seconds have elapsed in time counting (step 209), and when 8 to 9 seconds has elapsed, a time out occurs, and an announcement for the time out is sent (step 204).

Since the dial input timeout has been reached, the hook-on signal is received from the calling terminal, and the hook-off signal is received in order to redial immediately, and then it is executed again from step 200 (step 205).

If 8 to 9 seconds have not elapsed in time counting, next, it is determined whether 5 to 6 seconds has elapsed (step 210), and if 5 to 6 seconds has not elapsed, step 209 is executed.

When 5 to 6 seconds have elapsed, a specific sound for promptly inputting a digit number is transmitted to the transmitter / receiver of the calling terminal (step 211).

After the last digit number is received from the calling terminal (step 212), a ring back tone is sent to the calling terminal, and a ring tone is sent to the calling terminal (step 213).

Therefore, since the digit input timeout by dialing is prevented, the calling / receiving terminal is connected to the call and can normally make a call (step 214).

In conclusion, when 5 to 6 seconds have elapsed before the 8 to 9 seconds have elapsed in the MP 20, a specific sound for promptly inputting the next digit number is transmitted to the calling terminal, thereby controlling the timeout according to the digit input. It is.

As described above, the present invention described above rapidly dials the next digit number in 5 to 6 seconds before the timeout between digit inputs becomes 8 to 9 seconds in the process of the calling subscriber dialing the called party directory number using his terminal. Since a specific sound to be input is sent to the calling terminal, there is an effect that the dialing is prevented from the beginning by preventing timeout due to the digit input.
