The present invention relates to a method and a system for automatically providing an incoming call service, and more particularly, when a called terminal requesting a call from a calling terminal is busy, the called terminal does not retry a call connection after terminating the call. The present invention relates to a technology for automatically establishing a call path with a terminal.

In general, when the called terminal requesting a call from the calling terminal is busy, the calling terminal ends the call attempt and repeatedly retries the calling terminal. In particular, due to the widespread use of wireless terminals, if the terminal which initially attempted a call is a wired terminal and is busy, the calling terminal transfers the call attempt to the called party's wireless terminal.

Therefore, the repetitive call attempts add to the communication network, and there is a problem in that the revenue is reduced according to the amount of calls because the call connection is transferred wirelessly from the wireline operator's point of view.

On the other hand, in the case of the wireless terminal, when the called terminal is busy and the call is changed to a state in which the call can be made, the calling terminal may notify that the calling terminal has attempted the call using a predetermined message service function.

However, in the case of a wired terminal in which a text message service function is not universalized, the called party has a problem in that it is difficult to recognize that the calling terminal requests a call.

The present invention was created to solve the above problems, and an object of the present invention is that, when the called terminal requesting a call from the calling terminal is busy, the calling terminal does not have to retry the call repeatedly after terminating the call attempt. The purpose of the present invention is to automatically establish a call path between a calling terminal and a called terminal.

It is also an object of the present invention to notify the calling terminal that the called terminal is busy and to switch the incoming call to a second called terminal instead of the called terminal which initially attempted the call.

In addition, an object of the present invention is to be provided with an automatic connection service according to the present invention according to the selection of the calling terminal even without subscribing to the automatic connection service.

In addition, an object of the present invention does not use a predetermined service identification number (SAC: Service Request Code) for requesting to provide an automatic connection service, and the service control system provides an automatic connection service even without periodically attempting to make a call to the called terminal. It's about making it happen.

In order to achieve the above object, there is provided a method for automatically providing an incoming call connection service according to the present invention, a) a terminating exchange checks a state of a called terminal requesting routing at an originating exchange, and the called terminal is busy or idle. Triggering a call to the service control system when in an) state; b) the service control system requesting the destination exchange to monitor the state of the destination terminal from the service control system; c) the called exchange monitoring the state of the called terminal at the request of the service control system, and notifying the service control service system of the changed state when the state of the called terminal changes; And d) the service control system connecting a call path between the calling terminal and the called terminal.

And the automatic call connection service providing system according to the present invention for achieving the above object, an outgoing exchange for routing a call to the destination terminal requested by the originating terminal; A terminating exchange for checking a state of the terminating terminal; And as a result of checking the state of the terminal, requesting the destination exchange to monitor the state of the terminal when the called terminal is in a busy state or idle state, and when the state of the called terminal in a call is changed, the calling terminal and the And a service control system for connecting a call path between the optical receiving terminals, wherein the terminating exchange monitors the terminal state of the terminating terminal at the request of the service control system.

Hereinafter, with reference to the accompanying drawings and the preferred embodiment will be described in detail with respect to the method and system for providing automatic call connection service according to an embodiment of the present invention. Like reference numerals designate like elements throughout the drawings.

First, an automatic call forwarding service providing system according to an embodiment of the present invention will be described. 1 is a system configuration diagram for providing an automatic connection service according to an embodiment of the present invention, FIG. 2 is a configuration diagram of a destination exchange system according to an embodiment of the present invention, and FIG. 3 is a service diagram according to an embodiment of the present invention. The configuration diagram of the control system.

As shown in FIG. 1, the system for automatically providing an incoming call connection service according to an exemplary embodiment of the present invention includes an originating exchange 100, an incoming exchange 200, an intelligent network switch (SSP) 400, Service Control Point (SCP) 300 and Advanced Intelligent Peripheral (AIP) 500 and the like.

The originating exchange 100 routes an incoming call requested by the originating terminal 10.

The destination exchange 200 includes a service processor 210, a service control system connector 220, a database manager 230, and the like, and may further include a terminal authenticator 240.

The service processor 210 checks and monitors the state of the called terminal 20 requesting routing from the calling terminal 10. Checking the state of the called terminal 20 can be set as a call between the calling terminal 10 and the called terminal 20, and thus to determine whether a call can be made between the calling party and the called user. Means that. For example, when the called terminal 20 is in a call with another calling terminal or in an idle state, it is impossible to set a call between the calling terminal 10 and the called terminal 20, and at this time, the service processor 210 Recognizes the calling terminal 10 as an incoming call automatic connection service (hereinafter referred to as an 'automatic connection service').

In the present invention, when the incoming call automatic connection service is in a state in which a call path cannot be established between the calling terminal 10 and the called terminal 20, the called terminal 20 does not have to retry after ending the call attempt. When the terminal 20 is changed to a state in which a call can be set, the call path is automatically set with the calling terminal 10.

The monitoring of the state of the called terminal 20 means checking the state change of the called terminal 20 after checking the state of the called terminal 20. For example, it is checked whether the called terminal 20 which was in a call is changed into a callable state.

The service control system connection unit 220 is connected to the service control system 300 through the intelligent network switch 400, and transmits and receives predetermined information with the service control system 300.

For example, when the service processor 210 recognizes that the calling terminal 10 is an automatic connection service object after checking the status of the called terminal, the service control system connection unit 220 may identify the automatic connection service identification information (eg, 15XY) and identify the called terminal. The call is triggered by the service control system 300 by transmitting information and the like to the service control system 300.

In addition, the service control system connection unit 220 receives a request for monitoring a called terminal from the service control system 300 and determines whether to accept the request. In addition, the service control system connection unit 220 enables the service processing unit 210 to monitor the state of the called terminal 20 and informs the service control system 300 of the state monitoring result.

In addition, preferably, the service control system connection unit 220 may be connected to a plurality of service control systems, and when receiving a state monitoring request from a plurality of service control systems, transmits the state monitoring result information to the plurality of service control systems. Can be.

The database manager 230 stores state monitoring report information in a database (not shown). The state monitoring report information refers to information for reporting the state monitoring result to the service control system 300, and may include called terminal identification information, service control system identification information, and called terminal status information.

The terminal authenticator 240 checks whether the calling terminal 10 is valid, and checks whether the called terminal 20 is a callable line.

The intelligent network switch 400 is connected to the destination switch 200 and transfers the information transmitted from the destination switch 200 to the service control system 300.

As shown in FIG. 3, the service control system 300 includes a service reservation manager 310, a status monitoring requester 320, a call path manager 330, and the like.

When the service reservation management unit 310 receives the destination terminal status information indicating that the service control system 300 cannot establish a call path between the calling terminal 10 and the called terminal 20, the guide device 200, the guide apparatus. The receiver 500 transmits the called terminal state information to the calling terminal 10 and guide information indicating whether the calling terminal 10 desires automatic connection service reservation.

In this case, when the service reservation management unit 310 receives an automatic connection reservation request from the calling terminal 10 through the guide apparatus 500, the service reservation managing unit 310 may provide an automatic connection service to the calling terminal 10. It stores the information related to the automatic connection service reservation (hereinafter referred to as 'service reservation information').

The service reservation information may include the calling terminal identification information, the called terminal identification information, the destination exchange identification information, the automatic connection service reservation time and the automatic connection service reservation end time (hereinafter referred to as 'reservation end time').

On the other hand, the reservation end time means a time for ending work of monitoring the status of the called terminal. That is, if the status of the called terminal does not change to a state in which a call setting is possible within the reservation end time, the service reservation manager 310 may cancel the automatic connection reservation service reservation.

In addition, the service reservation management unit 310 may cancel the automatic connection service reservation when the calling terminal 10 does not respond to the call by the call when the call setting is made between the calling terminal 10 and the called terminal 20. For example, the service reservation manager 310 may cancel the automatic connection service reservation by canceling the stored service reservation information.

When the calling terminal 10 reserves the automatic connection service, the state monitoring requesting unit 320 requests the called exchange 200 to monitor the state of the called terminal 20, and the information on the called terminal status monitoring result. Is received from the destination exchange 200. For example, the state monitoring request unit 320 receives a report that the state of the called terminal 20 has been changed when the call of the called terminal 20 which is being called is terminated.

The call path manager 330 sets a call path between the calling terminal 10 and the called terminal 20 when the call exchanger 200 reports that the state of the called terminal 20 during the call has been changed.

On the other hand, the automatic connection service guide information may include the information that the originating terminal 10 can switch the incoming call to a second destination terminal (not shown) in addition to the destination terminal 20, the first attempt to call, In this case, the calling terminal 10 may request a call with the second called terminal.

In this case, the call path manager 330 switches the incoming call of the calling terminal 10 to the second called terminal. In this case, preferably, the automatic connection service may be provided to the second destination terminal.

Hereinafter, a method for automatically providing an incoming call connection service according to an embodiment of the present invention will be described in detail.

4 to 6 are flowcharts of a method for providing automatic connection service according to an embodiment of the present invention, and FIG. 7A is a message flow diagram for requesting monitoring of a terminating terminal state according to an embodiment of the present invention. 7 is a message flow diagram for requesting monitoring of a current state of a calling terminal according to an embodiment of the present invention.

As shown in FIG. 4, the calling terminal 10 attempts to make a call to the called terminal 20 that wants to make a call (S410). The originating exchange 100 requests routing to the called terminal 20 (S 420), and the called exchange 200 checks the state of the called terminal 20 requesting routing from the originating exchange 100 (S 430). .

As a result of the check, when the called terminal 20 cannot establish a call path with the calling terminal 10 such as during a call or an idle state, the called exchange 200 calls the service control system 300. Trigger (S440).

On the other hand, preferably, before the terminating exchange 200 triggers a call to the service control system 300, terminal authentication for checking the validity of the originating terminal 10 and whether the terminating terminal 20 is a line that cannot be received. The process can be performed.

The service control system 300 triggered by the call exchanger 200 transmits the service guide information to the calling terminal 10 through the guide apparatus 500 (S450).

However, as a result of the check, when the called terminal 20 is in a state of establishing a call path with the calling terminal 10, the called exchange 200 sets a call path between the calling terminal 10 and the called terminal 20. The call can be made (S435).

The service control system 300 checks the type of service requested by the calling terminal 10 (S460). That is, the calling terminal 10 may request an automatic connection service or request to switch the incoming call to the second called terminal through the service guide information.

For example, '*' may be set in advance as a digit for requesting automatic connection service reservation, and '#' as a digit for requesting an incoming call transfer, and the calling terminal 10 may be configured to switch when the incoming call transfer request is made. The recipient terminal identification information of 2 should be further input. Accordingly, the service control system 300 may provide a service according to the received specific digit.

First, a case in which the calling terminal 10 reserves the automatic connection service will be described. For example, when the calling terminal 10 inputs the '*' digit, it may mean that a request for automatic connection service reservation is made.

As shown in FIG. 5, the service control system 300 requests the destination exchange 200 to monitor the state of the destination terminal 20 (S510). In addition, the service control system 300 stores the service reservation information.

For example, the message flow for requesting the destination terminal status monitoring is shown in FIG. 7A. As shown in FIG. 7A, the service control system 300 transmits a RequestFirstStatusMatchReport (RFSMrep) message to the destination exchange 200. The RFSMrep message refers to a request message for monitoring a state change of a called terminal at a specific time.

The destination exchange 200 transmits a response message for receiving the RFSMrep message to the service control system 300. For example, the response message is a result of whether or not the status monitoring request has been accepted.

Subsequently, when the terminating exchange 200 accepts the state monitoring request, the terminating exchange 200 monitors the state of the terminating terminal 20 according to the state monitoring request and reports the state monitoring report information. It is stored (S520).

 When the state of the called terminal 20 is changed, the service control system 300 notifies that the state of the called terminal 20 has been changed (S530). For example, the message flow for the destination exchange 200 to inform the service control system that the state of the destination terminal 20 has been changed is shown in FIG. 7B.

As shown in FIG. 7B, the destination exchange 200 transmits a SRrep (Status Report) message to the service control system 300. That is, the SRrep message includes the content of reporting the status of the called terminal 20.

Subsequently, the service control system 300 extracts the calling terminal identification information based on the service reservation information, and determines whether the calling terminal 10 corresponding to the extracted calling terminal 10 can answer when the call is connected. (S540). For example, the message flow for requesting monitoring of the current state of the calling terminal 10 is as shown in FIG. 7C.

When the calling terminal 10 can respond to the call with the called terminal 20, the service control system 300 establishes a call path between the calling terminal 10 and the called terminal 20 ( S 550).

However, when the calling terminal 10 cannot respond to the call with the called terminal 20, the service control system 300 may cancel the automatic connection service reservation (S 555).

In addition, the service control system 300 may check the service reservation end time based on the service reservation information, and then cancel the automatic connection service reservation even when the end time has elapsed. For example, although not shown in the figure, the service control system 300 periodically determines whether the service reservation end time has elapsed.

When the service reservation end time has elapsed, the service control system 300 requests the destination exchange 200 to stop monitoring the state of the destination terminal 20.

The destination exchange 200 stops monitoring the state of the destination terminal 20 in response to the request.

Hereinafter, a case in which the calling terminal 10 requests the call forwarding service when the guide information is sent to the calling terminal 10 will be described. For example, as shown in FIG. 6, when the calling terminal 10 inputs the '#' digit, the service control system 300 is requested to provide the call forwarding service (S610).

The service control system 300 receives the second called terminal identification information from the calling terminal 10 (S620), and switches the incoming call of the calling terminal 10 to the second called terminal (S630). )

Although the present invention has been described in detail with reference to preferred embodiments, the present invention is not limited to the above-described embodiments, and the present invention belongs to the present invention without departing from the gist of the present invention as claimed in the following claims. Anyone having ordinary skill in the art will have the technical idea of the present invention to the extent that various changes or modifications can be made.

As described above, according to the present invention, the method and system for automatically providing the incoming call automatic connection service, even if the called terminal requesting the call is busy, the calling terminal does not automatically retry the call after terminating the call attempt. This has the effect that the currency path can be set.

In addition, when the called terminal is busy, an incoming call is switched to a second called terminal in addition to the called terminal, so that the calling terminal does not terminate the first call attempt but is identical to the call attempted to the second called terminal. The effect is to get the result.

In addition, the destination exchange provides an automatic connection service if the destination terminal cannot establish a call path even without receiving separate identification information from the calling terminal, and thus, the calling party user does not need to subscribe to a separate service. There is an effect that can be provided.

In addition, since the terminating exchange monitors the state of the terminating terminal and checks the state change of the terminating terminal, there is an effect of providing an automatic connection service without periodically attempting a call to the terminating terminal.

Therefore, it is possible to prevent the transfer of the call to the wireless terminal from the wire operator.
