The present invention is a missed incoming call number guide system and a guide method for a landline telephone, and more particularly, when a caller sends a call to the receiver's landline telephone but the call fails, the caller's telephone number is automatically stored. The present invention relates to a system and a method for guiding a stored caller's telephone number when a receiver requests a call for a missed call after connecting to a service number using a wired or wireless telephone.

In the case of fixed line telephone service, there are the following ways to check the call of missed caller. i) an answering machine with a built-in answering machine in the recipient's phone; ii) a CID method for displaying the calling party's phone number with a display means on the recipient's phone; iii) a call forwarding connection to another phone number when a missed call is received. Or take a call from voicemail instead (KT's pass call).

In the aforementioned i) and ii), there is a problem in that a user needs to purchase a separate dedicated phone, so that the user has to replace the existing phone. In addition, in the case of the iii) method, when a caller is connected to a voice mail box, there is a problem that most users do not gain utility because they do not hang up and leave a message.

Table 1 below shows the user call pattern in the wired / wireless receiver terminal according to the importance of the call.

division Receiver terminal User call pattern when incoming call fails An important call cable -Caller: Redial or Wireless Call-Receiver: Wait indefinitely until the call is available wireless -Caller: Redial-Callee: Caller ID (CID) service subscribers callback call after checking call detail Low priority call cable -Caller: Never redial-Callee: wait indefinitely until the call is available wireless -Caller: Do not redial-Callee: Caller ID (CID) service subscribers callback call after checking the call details

As shown in Table 1, in the case of the wireless telephone service, the missed call notification service is diversified through various paid services, and the existing home general landline telephone user cannot check the missed call. There is a desire to identify missed calls in an inexpensive manner.

In particular, the percentage of missed calls is about 50% of attempts to make calls from wireless telephones to fixed or wired telephones. In the case of home phones, the proportion of missed calls is estimated to be high.

The present invention is to solve the above-mentioned problems, when receiving a service request for a landline telephone subscriber, when the call reception fails in the service subscriber's phone to store the outgoing telephone number to guide the subscriber to the unreceived call information The state aims to provide missed call information service.

According to the missed incoming call number guidance system of a landline telephone of the present invention for achieving the above object, in the system for guiding the incoming telephone number when a call fails in the receiving landline telephone, a service special number is provided from the target landline telephone. Subscription application receiving unit for receiving a service call through the subscription request; An incoming call number storage unit that collects and stores missed incoming call information including an outgoing call number, a caller name, and a call time when a call is requested from the caller's wire / wireless telephone to the landline; A voice guide unit for receiving a call from a user's wired / wireless telephone through a service number and receiving an incoming call number guide request, and searching and storing the missed incoming call information by voice; And a subscription termination receiver for receiving a service call by receiving a call using a service number from a landline telephone subscription.

According to a preferred feature of the present invention, the missed incoming call number guide system, a service subscription information DB for storing service subscription information including landline telephone number, subscriber information, user password, automatic notification interval; And an incoming call information DB for storing the missed incoming call information including the caller's phone number, caller's name, call time, and user's hearing when the call fails in the wired telephone.

In addition, according to the missed incoming call number guide method of the landline telephone of the present invention, in the method of guiding the incoming telephone number when a call fails in the receiving landline telephone, (1) the call through the service number from the service target landline telephone; Receiving the service subscription request; (2) storing missed incoming call information including a caller's telephone number, caller's name, and call time when a call is requested from the wired / wireless telephone of the caller to the wired telephone that is subscribed to the service, but the call fails; (3) receiving a call through a service number from a wired or wireless telephone of a receiver and receiving an incoming call number guide request; (4) automatically collecting a telephone number if the wired / wireless telephone is a service-subscribed telephone line, and if not, receiving a telephone number of the wireline telephone to be inquired from a user; (5) determining whether the telephone number is a service subscription; And (6) inquiring the missed incoming call information stored therein and guiding it by voice.

Hereinafter, a preferred embodiment of the present invention including the above components will be described in more detail with reference to the accompanying drawings.

1 illustrates the concept of a missed incoming call number guide system 1 according to an embodiment of the present invention.

In one embodiment of the present invention, the guidance system 1 transmits a call to the receiver's landline telephone 3 using the wired / wireless telephone 2, and receives incoming call information at the receiving side when the call fails for other reasons. After storing, the recipient calls the service providing telephone number (for example, XX114, hereinafter referred to as "service special number") to request a guide, and the calling telephone number information is voiced.

For example, if the call failure occurs, the caller hangs up because the receiver landline 3 is busy or rings but the receiver does not receive the call. The occurrence of such a call failure is detected at an exchange, for example an exchange server, which connects the caller's call to the called party.

Accordingly, the guidance system 1 of the present invention may be integrated in the exchange server or may be constructed as a separate independent server to receive a call failure history.

2 conceptually illustrates the functional blocks constituting the missed incoming call number guide system 1 according to an embodiment of the present invention.

Guide system 1 according to an embodiment of the present invention is a subscription request receiving unit 11, incoming call number storage unit 12, voice guide unit 13, automatic call connection unit 14, automatic guidance notification unit 15 ) And the unsubscribe receiver 16. In addition, the DBMS structure includes a subscription information DB 110 and an incoming call information DB 120.

The subscription request receiving unit 11 receives a call connection from a user (receiver), receives a subscription request for a missed incoming call information service, and stores the information in the subscription information DB 110. Preferably, the subscription request receiving unit 11 is configured to include an automatic guide voice unit 111 and password setting unit 112.

The automatic guide voice unit 111 induces a subscription to a service by providing a guide voice by receiving a call in which a user calls a service number to a receiver's phone number. Here, it is more preferable that the user makes a call connection to the wired telephone 3 which is the object of the service, and the corresponding telephone number is automatically recognized and the service subscription application is made. Of course, it is also possible for the user to make a call with another wired or wireless telephone and input the telephone number of the wired telephone 3 of the service target, but in this case, the telephone number of the wired telephone 3 is separately input and service is possible (for example, , The existence of the telephone number, the possibility of making a call, etc.). In addition, the subscription to the service may be denied subscription depending on whether the corresponding telephone line 3 is overdue.

 The password setting unit 112 receives a password for the wireline telephone 3 of the service subscription target from the user. This is because the outgoing telephone number where a call failure occurs in the landline phone 3 is a kind of personal information, and a predetermined authentication method is required for the user who listens to, deletes, or cancels the service. If the user does not specify a password separately, the default password may be the default four-digit number of the landline telephone (3).

The incoming call number storage unit 12 determines whether the incoming call number is a service subscription whenever a call failure occurs in the exchange station shown in Fig. 1, and the incoming call number, i. The missed incoming call information is stored in the incoming call information DB (120). The missed incoming call information (see Table 3) includes the incoming call number, caller name and call time.

The voice guide unit 13 receives a call request requested by the user using a service special number, and when the user presses a selection key of the incoming call number guide request, receives a password and authenticates whether the user is a valid user. The incoming call information stored in the incoming call information DB 120 is retrieved for each case and guided by voice. A well-known text-to-speech engine is used for voice guidance.

Information that the user listens to includes the called phone number, the caller's name, and the call time. Here, the caller name is a subscriber name (name or business name) subscribed to the wire / wireless telephone communication company. When the caller uses a landline telephone number, the caller name can be inquired by inquiring the customer DB by the calling telephone number. In addition, even if the recipient and the caller's telephone company are different, the wired / wireless lettering service (that is, the name (phrase) that the wired / wireless caller can represent himself or herself) is included in the configuration field of the outgoing call when the call is made and the called party is If there is a receiving window, the service displays the caller's name through the caller ID).

The automatic call connection unit 14 when the user listens to the individual missed incoming call information is switched to the confirmation state, and asks whether to automatically connect to the incoming call number through the guide voice, and the user automatically enters the call when the selection key Connect. It also inquires whether to delete the individual missed incoming call information that is confirmed and deletes the data according to the user's selection key. Preferably, the deleted data is stored in a separate DB for one month so that it can be recovered again according to a separate request of the user.

The automatic guidance notification unit 15 selects and stores a predetermined automatic notification interval from a user who has subscribed to the service, and registers and stores a service, and if there is at least one unidentified missed incoming call number in the incoming call information DB 120, requests for service. Only one user makes a call to the wired telephone 3 at the automatic notification interval and notifies that there is unidentified call information through an automatic guide voice and asks whether to listen.

The subscription canceling unit 16 terminates the missed incoming call information guide service of the present invention by receiving the user's call and confirming the subscriber's password and deleting the corresponding data from the subscription information DB 110 according to the user's service termination request. do.

The subscription information DB 110 is used to store data generated when a user subscribes to a service and determine whether to subscribe to a service. Table 2 below illustrates the data structure of the subscription information DB 110, but is not necessarily limited thereto.

Subscription Information DB (110) Landline phone number + subscriber information (name, social security number) + user password + automatic notification interval + etc.

The incoming call information DB 120 stores missed incoming call information including the wired / wireless telephone number 2 of the caller who failed the call, and is referred to each case and voiced to the user. Table 3 below illustrates a data structure of the incoming call information DB 120, but is not necessarily limited thereto.

Incoming Call Information DB (120) Incoming phone number + Caller's name (name or business name) + Call time (Incoming time) + User listening status + etc.

Figure 3 shows the entire procedure of the missed incoming call number guide method according to an embodiment of the present invention.

In order to receive the missed incoming call information guide service provided by the present invention, the user connects a call using the service number in the wireline telephone 3 as a service target and applies for a service subscription (S10).

4 is a detailed flowchart of the step S10. Referring to FIG. 4, the system 1 receives a user's call and sends out an automatic guide voice to guide service subscription and selects a service subscription request selection key selected by the user. Receive (S11), a request for the personal information (for example, social security number) of the subscriber to the landline telephone (3) subscriber to pay for the service provided by the present invention, the subscriber of the landline telephone that has already stored the received personal information Subscriber authentication is performed in comparison with the information (S12). The authentication process compares the personal information and at the same time compares the automatically detected telephone number with the telephone number registered in the personal information according to the call connection of the user and determines whether there is a match. If the authentication is successful, ask the user whether to set a password (S13) .If not, set the four-digit number of the telephone number (3) as the default password if the default password is not set (S14). Set and register the four-digit key button as a password (S15).

Referring to FIG. 3, when a caller fails to make a call by using a wired / wireless telephone 2 to the recipient's landline telephone 3, the system 1 returns the missed incoming call information including the caller's telephone number ( (See Table 3) (S20).

FIG. 5 is a detailed flowchart of the step S20. Referring to FIG. 5, in the intelligent network exchange, the receiving landline telephone 3 detects a call failure of an incoming call when the receiver does not receive a call for other reasons (S21). . In response to the call failure, the subscription information DB 110 is queried using the telephone number of the receiving landline telephone 3 to determine whether the service is subject to subscription (S22). If the service is subscribed, it is determined whether an outgoing telephone number exists (S23). In some cases, when the caller prohibits the disclosure of the calling number, the calling number may not exist. If the calling number exists, the missed incoming call information as shown in Table 3 above is generated and stored in the incoming call information DB 120 (S24).

Referring to FIG. 3, the user makes a call connection to the system 1 using a service special number, receives an ARS automatic guidance voice, and requests a missed incoming call information guide (S30). If the user has a landline telephone 3 subscribed to the service, the telephone number is automatically collected (S40). On the other hand, when the user is connected to the other phone, the user requests the input of the telephone number (3) phone number of the service target through the automatic guide voice and receives it (S41).

Receiving a phone number, the system 1 checks the subscription information DB 110 to determine whether the requested phone number is a service target, and if a service target, inputs a password from the user and the password of the subscription information DB 110. In contrast, user authentication is performed.

If the user authentication is successful, the individual missed incoming call information is read from the incoming call information DB 120, and the missed incoming call information including the incoming call number, the caller name and the call time is voiced to the user through the TTS engine (S60). ).

FIG. 6 is a detailed flowchart of the step S60. Referring to FIG. 6, the confirmation status of the individual missed incoming call information guided after the voice guidance is updated to " on " Inquires whether or not to automatically connect to the call (S61). When the user selects the automatic connection, the call is automatically sent to the incoming number as the receiving number (S62). If the automatic connection is not selected, it is inquired whether to delete the missed incoming call information that has just been listened (S63), and when the user selects deletion, the corresponding data of the incoming call information DB 12 is deleted (S64). Here, after the step S62, the user may end immediately after the call with the caller.

As described above, an embodiment of a missed incoming call number guide system and a guide method thereof in a landline telephone according to the present invention are constructed. Although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical spirit of the present invention and the claims to be described below by those skilled in the art to which the present invention pertains.
