Description

Immediate line service method

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to the field of computer and exchange equipment integration (hereinafter referred to as CTI) of information and communication technology, and in particular, to be used in addition to a public terminating electronic exchange to reduce incomplete calls due to busy and missed calls. The present invention relates to a method for providing an immediate line service, which provides an additional service of a telephone message forwarding service and improves a service quality of a voice messaging service such as a 700 service and an answering service.

Immediate line service is an environment in which an electronic exchange and a computer system interoperate with each other so that a number can be transmitted and received to each other.The computer system requests the caller as a voice announcement at a specific stage of the service scenario, and the caller uses his or her own telephone. If you enter a phone number and the computer system recognizes and stores it, and the service operator or service subscriber wants to access the computer system and connect to the caller's phone number, the computer system generates a call to the stored caller's phone number. It is a service that connects caller and caller.

Recently, there has been a rapid increase in the case of providing voice messaging services by interworking computer systems and switching devices in the public network, including 700 services, automatic response services (hereinafter referred to as ARS), and telephone message delivery services (TMDS below the Telephony Message Delivery Service). This is a representative example.

However, the existing services mostly provide one-sided information in which the caller retrieves various data stored in the called party's computer, and provides two-way information transmission by including a connection with a receptionist in the service contents. In many cases, the caller waits for a long time or the connection between the called party and the called party is not smooth.

In addition, although the telephone number for the inquiry is guided to the caller through the announcement, there is a hassle to call another call for the caller.

In the case of the recently commercialized telephone message forwarding service, when the incoming service subscriber is busy or in an unanswered state, the computer system receives the caller's call by the call transfer function of the called party's electronic exchange and records the voice message, and the computer system periodically This is a one-way service that delivers the recorded message by calling the incoming service subscriber, and includes only the option of recording the message to the caller.

According to the result analysis of the telephone message delivery service pilot service, which was recorded in the Korean Society of Communication Sciences Fall Conference 1996, the recording rate of the caller using this service was extremely low at less than 30%. It is interpreted as a habit of unfamiliar phone users.

Accordingly, there is a characteristic of bidirectional information transmission between the called party and the calling party, and regardless of the line capacity of the voice messaging system, any caller using the voice messaging service and a service operator or service subscriber can be connected without using a voice message. The provision of a service method is required for a communication consumer, and such a service can be configured as an application program in an operating environment of a computer system capable of transmitting and receiving a number with an existing electronic exchange and having a call connection function.

Accordingly, the present invention was devised to solve the above-mentioned problems of the prior art, and is an additional service of a telephone message forwarding service used in addition to a terminating electronic exchange of a public network in order to reduce incomplete calls due to busy and absent calls. The purpose of the present invention is to provide a method for providing an immediate line service to improve the service quality of voice messaging services such as 700 services and answering service.

Hereinafter, with reference to the accompanying drawings will be described in detail the operating principle according to the present invention.

1 is an exemplary diagram showing an interworking environment between an electronic exchange and a computer system to which the present invention is implemented.

As shown in FIG. 1, an environment for applying an instant line service providing method according to the present invention includes a computer system 10 capable of transmitting and receiving numbers using an R2 signaling method; An electronic exchanger 20 in which the relay line circuit 21 and the subscriber circuit 22 are mounted; The computer system 10 may be configured as a T1 or E1 relay line 30 for interworking with the electronic switch 20.

The environment to which the present invention is applied is also possible in an intelligent network using No. 7 signaling.

The computer system 10 used in the example includes a central control unit 11, a signal processing circuit 12, a relay line circuit 13, and a database 14 for the processing of the work of the present invention.

Now look at the function and configuration of the above components.

The central control unit (11) manages the operating system (O / A) and utilities, and when the call is taken over from the called party's electronic exchange 20, it requests the caller's telephone number and stores it in the database 14, and later the computer system. In response to a request of a service operator or a service subscriber connected to (10), a caller's telephone number is called to control an application program that performs a process of connecting a caller and a caller.

The signal processing circuit 12 generates a corresponding event by selecting DTMF or R2 signal data among data input through the relay line circuit 13, and generating DTMF or R2 signal data at the time of automatic transmission for the caller / caller connection. It generates and outputs to the relay line circuit 21.

In addition, the present invention processes the use of various announcements and corresponding services, and the speech encoding according to the speech compression algorithm.

The relay line circuit 13 receives and synchronizes the clock of the electronic switch 20 so that data can be transmitted and received between the electronic switch 20 and the computer system 10 in units of T1 / E1. The relay line of the electronic switch 20 receives various signals DTMF, R2, and voice which are inputted, and transmits them to the signal processing circuit 12 through the system bus or signals such as R2 and DTMF input from the signal processing circuit 12. It performs the function of transmitting to the circuit 21.

In addition, the service operator or subscriber connected to the computer system 10 recognizes that there is a telephone number of a caller who has been input in advance through the announcement broadcast from the computer system 10, and then presses the telephone button for connection request. When inputting, the calling telephone number is called by using the R2 signaling method, and when the caller answers, the caller's call is connected with the caller's call.

2 is a flowchart illustrating an overall process of a method for providing an immediate line service according to the present invention.

Looking at the processing process using the drawings as follows.

When the service according to the present invention is in operation, when the caller generates a call for information retrieval stored in the computer system 10 (110), the computer system 10 during the information retrieval returns at an appropriate stage during the information providing. The caller requests the calling telephone number for the call (111).

The caller inputs a telephone number to be received in the future by using his / her telephone button (112), and the computer system 10 receives it and temporarily stores it in the database 14 (113).

The caller ends the call using the computer system 10 such as information retrieval (114).

Subsequently, when the service operator or the service subscriber connects to the computer system 10 for operation or other service operation (115), the computer system 10 transmits through the announcement that there is a reply request by the stored telephone number. 116, if the service operator or service subscriber requests a connection with the original caller using a predetermined telephone button (117), the computer system 10 automatically calls the stored caller's phone number (118).

At this stage, the computer system 10 must have a mailbox configured for use by a service operator or a service subscriber only. In a voice messaging system such as 700 service or ARS, the calendar memory is allocated as an operator mailbox. The call can be secured using a password for the operator access using the button on the hidden phone.

In the next step, the caller answers the screen 119, and the computer system 10 connects the call that has already been received with the call to the call (120).

3 is a detailed flow diagram of the sender side of a procedure in which a computer system interworking with an electronic exchange processes a service method.

With the service according to the invention in operation, a call by any originator for retrieval of information stored in the computer system 10, as shown in FIG. When the call is received by the computer system 10 (101), the computer system 10 reproduces the information according to the service scenario defined by the caller's request (102), and then announces the outgoing telephone number for the reply at the designated step. The caller is requested (103).

Here, if the reply request confirmation key by the sender is not input, information playback is performed according to a predetermined service scenario (104), and when the reply request confirmation key is input, the announcement broadcast to input the caller's telephone number is transmitted (105). Checking whether the number has been inputted and re-requested when not entered (106), and if entered, stores the entered calling number in the database (14) (107).

4 is a flowchart of detailed processing of a terminating service subscriber side of a procedure in which a computer system interworking with a terminating electronic exchange processes a service method.

If a connection from the service operator or service subscriber to the computer system 10 is made later (201), the presence or absence of a reply request message is confirmed (202), and if there is no other procedure (203), a reply request is performed. If there is a message, the announcement broadcasts it (204).

Checking the connection request key input from the service operator or the service subscriber (205), if there is a connection request, and attempts to automatically call to the pre-stored caller telephone number (206).

When the caller who leaves the telephone number answers and the call is connected between the computer system 10 and the caller (207), the computer system 10 removes the call of the service operator or service subscriber who has already been received by the computer system 10. As shown in (b) of FIG. 5, it connects to the caller's call (208).

The immediate reply service by this service method, when there are multiple reply requests and connects multiple callers and callers, the first reply requester causes the service operator Ehy to terminate the call before the service subscriber, and the service operator or service subscriber Since the first caller does not press the hook switch of the telephone even after the call is terminated, it is possible that the computer system makes a call to the next caller's telephone number and connects an incoming / outgoing call again.

As described in detail above, the present invention, in the case of the 700 service and the voice wife service receives the caller's telephone number, and the operator automatically responds to this, thereby enhancing the service quality and the efficiency of the operation, and in the case of the telephone message delivery service. By increasing the caller's choice, the efficiency of the equipment can be doubled.
