System and Method for Providing Information Service of Call Incapability in Wired / Wireless Communication Network}

The present invention relates to a system for guiding a non-call situation, and more particularly, a subscriber's non-call guiding service providing system in a wired / wireless communication network for guiding a caller's impossibility when a subscriber cannot answer an incoming call. And to a method.

With the development of communication technology, anyone is now equipped with wired and / or wireless communication means, and in particular, it is possible to use communication services regardless of time and place according to the high penetration rate of wireless terminals. While the development of communication technology has the advantage of eliminating the limitations in using the communication service as described above, it causes various problems due to the indiscriminate use of the communication service.

In particular, in public places such as schools, public transportation, and venues, ringtones and call sounds that do not consider others are considered noise levels, and ringing continues to occur even when you cannot respond to a call request, such as during a meeting or driving. There is a problem that ringing interferes with the work or driving of the called party.

This problem is not limited to the called party or those around him. If the caller does not answer the call, the caller does not know what the caller is and feels frustrated. Therefore, the caller continues to attempt redial. In addition, even when the call is switched to the message storage mode (voice or call) because the called party does not answer, there is a disadvantage that the caller must wait for the caller to reply after saving the message.

The present invention has been made in order to solve the above problems and disadvantages, the communication service subscribers can not answer the call request registered the call impossible situation, if the call is attempted to the subscriber the caller of the subscriber is not available situation There is a technical problem in providing a system and a method for providing a non-call guidance service that can solve the caller's frustration with respect to a subscriber's non-response.

In addition, the present invention provides a system and method for providing a non-call guidance service that can guide a call by informing the subscriber by using a text message the incoming call history according to the caller's attempt when the subscriber is in a call impossible situation, There are other technical challenges.

Another technical problem of the present invention is to check the unavailable time specified by the subscriber, and to notify the caller of the remaining non-call time so that the caller can attempt to redial after the end of the unavailable call.

The present invention for achieving the above-described technical problem is connected to a wired communication system and a wireless communication system, if the subscriber can not answer the call received by the wired or wireless communication service is received and stored the call impossible situation and the call A system for providing a non-call guidance service for informing a caller of a state in which a subscriber cannot call when a call is attempted to a subscriber who has registered a state of inability, wherein the wired or wireless communication system is configured to respond to an incoming call by the wired or wireless communication service subscriber. If it is not possible, whether or not to use the non-call guidance service in the wired switch or wired switch system of the wired communication system that stores the wired or wireless communication service subscriber information stored in the home location register of the wired communication system, the call impossible guide service providing system is Wired or wireless communication Receives and stores the call unavailable status information from the service subscriber, and generates a notice to notify the caller that the called party is not available when the wired or wireless communication service subscriber attempts to make a call to the call unavailable guide service user. To the calling subscriber terminal via the wired or wireless communication system.

In addition, the present invention is connected to a wired communication system and a wireless communication system, if the wired or wireless communication service subscriber is unable to answer the call received by the receiving and storing the call impossible situation to the subscriber registered with the call impossible situation A method of providing a non-call guidance service in a non-call guidance service providing system for guiding a caller of a subscriber when a call is attempted, as a call is attempted to a user of the non-call guidance service, the wired communication system or wireless Receiving a call attempt request, called party (service user) information, and calling party information from a communication system; Retrieving the call impossible situation information registered by the service user; And generating a announcement including the call unavailable situation information and transmitting the announcement to the caller terminal.

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

1 is an exemplary diagram of a communication network to which a system for providing a non-call guidance service according to the present invention is applied.

The non-call guidance service providing system 40 is connected to the wireless terminal 10 through the wireless communication system 30 and the base station 20, and is connected to the personal computer 50 through the Internet 60, public telephone It is connected to the landline telephone 80 through the switching network PSTN 70. The subscriber of the wired or wireless communication service registers to use the non-call guide service providing system 40 through the wireless or wired Internet using the wireless terminal 10 or the personal computer 50. At this time, if the call is attempted to the subscriber by registering the reason, period, etc. that the call is not possible, the caller may be informed of the reason, period, etc. of the call.

In addition, the non-call guidance service providing system 40, when a call is attempted to the user of the non-call guidance service, the home location register (HLR) 306 of the wireless communication system 30 or the wired switchboard of the public switched telephone network 70 (not shown). The call attempt is received from the subscriber and the reason why the subscriber cannot be called and the remaining time is extracted. The announcement is generated and sent to the calling terminal.

Accordingly, the caller can recognize the reason why the subscriber can not be called, and does not attempt a meaningless redial before the remaining time expires. In addition, the non-call guidance service providing system 40 may induce the subscriber's reply call by notifying the subscriber that the call is received through the wireless communication system 30 or the public switched telephone network 70, and the caller's call to the subscriber. By notifying the remaining remaining time, the sender can try to redial after the remaining time expires.

On the other hand, the wireless communication system 30 includes a base station controller (BSC, 302), switchboard (MSC, 304) and home location register (HLR, 306), the base station controller (BSC, 302) is a base station 20 Through the wireless terminal 10 to be connected to the wireless communication system 30 and manages the base station 20. In addition, the exchange (MSC) 304 is connected to the base station controller 302 to perform call setup and release functions of the wireless terminal 10, perform various functions related to call processing and supplementary services, and to communicate with other networks. Enable interworking. The home location register (HLR) 306 is a database that stores information of the subscriber of the wireless terminal 10, location information, additional service information, and the like. The home location register (HLR) 306 interacts with the exchange 304 and the visitor location register (not shown). It performs the functions related to processing and supplementary services and controls the services.

The non-call guidance service providing system 40 may be operated by a wireless communication system operator or operated by a separate operator from a wireless communication system operator.

FIG. 2 is a detailed configuration diagram of a system for providing a non-call guidance service shown in FIG. 1.

As shown, the non-call guidance service providing system 40 includes a user management means 402, a call unavailable status registration means 404, a shortcode decode means 405, a call unavailable status guide means 406, and a call impossible. And a time counting means 408, a text message generating means 410, a voice message generating means 412, a remaining time notification means 414, a controller 420 and a database 430. Here, the database 430 includes a user DB 432, a non-call situation DB 434, a announcement DB 436, a message DB 438 and a short code DB 440, one database It can be configured as a table or can be configured as a separate table.

The user management means 402 stores and manages wired or wireless terminal user information for using the non-call guidance service in the user DB 432, and the user DB 432 is a wireless communication system 30 or a PSTN 70. It is preferable to use the user DB provided in the sharing.

The call-free situation registration means 404 receives a call-free information from the subscriber who wants to use the call-free guidance service through any one of a wireless terminal, a personal computer, and a landline telephone, and includes the call-free information including the reason for the call failure and the call duration. Store and manage in the impossible situation DB (434). The non-callable period can be selected by time unit or date unit and can receive and store detailed period (hours or days) information. In this case, the call-free situation registration sends a guide to the subscriber to select the reason and duration of the call and the like by referring to the guidement DB 436 and register the call-free information accordingly.

It is also possible to register a call impossible situation by a short code. The short code decoding means 405 is for this purpose. When the subscriber registers a call impossible situation using the wireless terminal, the short code decoding unit 405 receives a specific short code from the subscriber wireless terminal and refers to the short code DB 440. The meaning may be extracted and transmitted to the non-call state registration unit 404 to store the non-call state in the database 434.

For example, a short code corresponding to a reason and duration of a call cannot be stored in a database as shown in [Table 1], and a subscriber transmits a short code indicating a non-call information along with a short code indicating activation of a non-call guidance service. Then, it decodes what the corresponding short code means and registers a call impossible situation. Here, the non-call guidance service activation code and the non-call information shortening code may be made of numbers, symbols or a combination of numbers and symbols.

For example, if the subscriber enters the non-call activation code (for example, * 77) and 01 + 2 + 0130, the subscriber registers that the call is unavailable for 1 hour and 30 minutes due to the meeting. * 77 and 02+ If you enter 1 + 0003, you are registering that you will not be able to talk for three days on a business trip.

Reason for not calling code Call deadline code Incapable period 01 (meeting) 1 (DAT) Specify the desired day or time unit (two digits for time, two digits for minute) 02 (business trip) 03 (driving) 2 (hour unit) 04 (class) 05 (customized)

In the preferred embodiment of the present invention, when the subscriber registers the call unavailable situation, the call impossible situation registration means 404 may select whether to block the received call unconditionally or to switch the terminal to the silent state.

If a call is attempted to the corresponding subscriber after the user cannot register the call, the user can call the subscriber by referring to the call unavailable situation DB 434 and the announcement DB 436. The announcement will be sent in the announcement. For example, 000 may send a prompt such as Cannot receive a call during a meeting until 3:30 pm so that the caller can recognize the subscriber's inability to talk and the duration of the call. In one embodiment of the present invention, it is also possible to allow the subscriber to foster a non-call situation.

The non-time counting means 408 checks how much time left in the non-call after the subscriber registers the non-call situation. By checking the unremaining time in the unreachable time, if a call is subsequently made to the non-calling guide user, the caller can send out the remaining unreachable time of the subscriber as a guide or send a text message. After the deadline, the subscriber can try to redial.

The message generating means 410 includes caller information (name, phone number, etc.), incoming time, etc., when a call is attempted to the corresponding subscriber after the user cannot activate the call and registers a call impossible situation. An incoming call detail message is generated and stored in the message DB 438, and the incoming call detail message is immediately transmitted to the corresponding subscriber after the unavailable period of the corresponding call expires or immediately. In the case of transmitting a text message to the subscriber immediately, the subscriber's terminal should be set to the silent state when the call cannot be registered.

The voice message generating means 412 allows the caller to record a message by voice when a call is attempted to the subscriber after the user cannot register the call, and if the caller records a message, the caller information and the voice message are recorded. The voice message is generated and stored in the message DB 438, and the voice message is transmitted to the subscriber after the unavailable time of the corresponding subscriber expires.

Remaining time notification means 414 receives the non-call remaining time from the non-call time counting means to the caller who attempted to call the non-call guidance service user to generate a message including subscriber information, the reason for the non-call, and the non-call remaining time. Stored in the message DB 438, and transmits the message to the terminal of the caller who attempted the call at least once to the subscriber. The remaining time can be informed not only to the caller but also to the subscriber, and in this case, the subscriber's terminal should be set to switch to the silent state when the call is not registered.

Although not shown, the non-call guidance service providing system 40 of the present invention further includes a charging means, and extracts a usage fee according to the usage history of the non-call guidance service of the subscriber, and periodically sends it to the communication system to which the subscriber belongs. Service charges can be settled accurately.

3 is a flowchart illustrating a service activation method in the method for providing a non-call guidance service according to the present invention.

The user of the wireless terminal 10 who wants to use the call guide service requests to register a call impossible service to the home location register 306 of the wireless communication system 30 through a customer oriented information system (COIS) (S101). In operation S102, the home location register 306 checks whether the user of the wireless terminal 10 is a legitimate user. After that, if it is determined that the user is a legitimate user, the database field related to the non-call guidance service is changed to an active state in the database storing the subscriber's location information and the additional service usage history (S103), and the result is transmitted to the COIS. (S104).

Subsequently, the COIS requests the use of the non-callable guidance service to the non-callable guidance service providing system 40 (S105), and the user management means 402 of the non-callable guidance service providing system 40 authenticates whether the user is a legitimate user. (S106). Thereafter, if it is determined that the user is a legitimate user, the user management means 402 of the non-call guidance service providing system 40 modifies the database 432 to indicate that the subscriber is a non-call guidance service user and activates the service (S107). , And transmits the registration result to the COIS (S108). Here, COIS is a customer-oriented information system that is designed, built, and operated in a wireless communication system. It means a comprehensive information system that manages customer management, billing, billing, and payment.

In the present embodiment, a case of registering a service through COIS has been described. However, the service registration can be performed in any possible manner, such as an Internet connection using a personal computer, a wireless Internet access using a wireless terminal 10, and an automatic answering service using a wired telephone 80. It can be carried out by any of the methods.

4A and 4B are flowcharts illustrating a service registration process in the method for providing a non-call guidance service according to the present invention, and FIG. 4A is a state in which a call is not available according to the announcement sent from the non-call guidance service providing system 40. 4B is a flowchart illustrating a case in which a call unavailable situation is registered by transmitting a service use request short code to the call unavailable guide service providing system 40 using a wireless terminal.

First, referring to FIG. 4A, as described above with reference to FIG. 3, a subscriber of a wired or wireless communication system that activates a call unavailable guide service may register a call unavailable situation when it is unable to answer an incoming call. To this end, when one of the wireless terminal 10, the personal computer 50, and the wired telephone 80 is connected to the call impossible guidance service providing system 40 and requests service registration (S201), the call impossible guidance The call impossible situation registration means 404 of the service providing system 40 allows the corresponding subscriber to input a reason for not being able to call (S202).

Accordingly, when the subscriber inputs one of various reasons for not being able to talk, for example, a meeting, a business trip, driving, and a class (S203), the call possibility status registration means 404 inputs the period for which the user cannot talk. (S204). The subscriber enters the period of no call in units of days or hours (S205), and the non-call state registration means 404 of the non-call guidance service providing system 40 uses the received non-call reason and the non-call period. The impossible information is generated and stored in the call impossible situation DB 434.

Thereafter, the non-call information is transmitted to the HLR 306 to which the subscriber belongs, so that the call attempt request can be switched to the non-call guidance service providing system 40 when a call is attempted to the subscriber.

Although not shown, after the non-call state is registered in this manner, the non-call time counting means 408 of the non-call guidance service providing system 40 starts counting the non-call remaining time, and the remaining time notification means 414 A message containing the remaining unreachable time is created and transmitted to the corresponding subscriber every designated period.

In addition, after step S205, before performing the step S206 of storing a call unavailable situation, it is also possible to further perform a step of selecting whether to block an incoming call unconditionally or to switch the terminal to a silent state. .

Next, referring to FIG. 4B, when the user of the non-call guidance service is the user of the wireless terminal, the subscriber of the wireless communication system may use the wireless terminal together with the non-call guidance service activation code (for example, * 77) and the reason for not being able to call. The short code indicating the non-call information including the non-call period is transmitted to the non-call guidance service providing system 40 (S250).

The short code decryption means 405 of the call impossible guidance service providing system 40 extracts a reason for not being able to call and a call unavailable period from the short code received with reference to the short code DB 440 (S251) and extracts the extracted contents. The call-free situation registration means 404 is transmitted to store the call-free information of the subscriber in the call-free situation DB 434 (S252).

Thereafter, the subscriber's non-call situation is transmitted to the HLR 306 so that the call attempt is switched to the non-call guidance service providing system 40 when a call is attempted to the subscriber. Here, the short code indicating the non-call information can be implemented as in the example of [Table 1] described above.

Further, in addition to the short code indicating the reason for the non-call and the non-call period, a short code indicating whether to block the received call unconditionally or switch the terminal to the silent state may be further included.

In this manner, even after registering the call-free situation by using the short code, the call-free time counting means 408 of the call-free guidance service providing system 40 starts counting the call-free remaining time, and the remaining time notification means 414. Prepares a message including the remaining unavailable time and transmits the message to the corresponding subscriber every designated period.

FIG. 5 is a flowchart illustrating a method for providing a call impossible situation in a method for providing a non-call guidance service according to the present invention. As an example, a caller using a wireless terminal attempts to call a subscriber of a wireless communication system using a non-call guidance service. Indicates.

As the wireless terminal user attempts the call (S301), the calling party HLR transmits the call attempt request and the calling party information to the called party HLR (S302). The called party HLR searches the database to determine whether the called party is a user who can not call the guide service (S303). If the called party is confirmed as a user who can not call, the call attempt and caller information is transmitted to the system for not providing a call service. The user management means 402 of the non-callable guidance service providing system 40 checks whether the corresponding subscriber is a legitimate user (S305), and if it is determined to be a legitimate user, uses the non-call time counting means 408. Check the remaining time unavailable for communication (S306). Subsequently, the call impossible status guide means 406 generates a call unavailable status guidement with reference to the stored call impossible status DB 434, the guide comment DB 436, and the remaining unavailable time for each subscriber (S307). The message is sent to the caller's wireless terminal (S308).

In this way, the caller can recognize that the subscriber is in a state where the call is unavailable for some reason and can try to redial after the deadline time expires.

In a preferred embodiment of the present invention, after the step (S308) of sending out the call impossible situation announcement, the text message generating means 410 or the voice message generating means 412 of the call unavailable guidance service providing system 40 sends to the caller. A call number or a voice message is input (S309). Accordingly, when the caller inputs the call number or the voice message (S310), the text message generating means 410 or the voice message generating means 412 of the non-call guidance service providing system 40 sends the call number or voice message and the caller. A text message or a voice message including the information is created (S311) and stored in the message DB 438, so that it can be transmitted to the subscriber immediately or after the deadline.

In addition, the remaining time notification means 414 of the non-call guidance service providing system 40 receives a non-call remaining time from the non-call time counting means 408 to designate a message including a remaining call remaining time to the caller or subscriber. It transmits every cycle (S312). In this way, the caller can try to redial without forgetting after the deadline time expires, and the subscriber can also check the state of his / her non-callable service usage.

In this embodiment, although the user of the wireless terminal attempts to call a subscriber to the wireless communication system using the call-free guidance service, the call-free guidance of the present invention is also performed between the wireless-wired terminal, the wire-wireless terminal, and the wire-wired terminal. Of course, the service providing method can be applied. If the called party or the calling party is a subscriber of the wired communication system, the calling party and the called party information are stored in the wired switchboard of the PSTN 70, and if a call is attempted to the wired terminal user using the non-call guidance service, the calling party wired switch is connected to the subscriber from the subscriber information. By extracting the user who can not call the guide service, the call attempt request is converted to a call guide service providing system so that a call is not sent to the subscriber and a call announcement is sent to the caller.

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

As described above, according to the present invention, when the subscriber of the wired or wireless communication system cannot answer the incoming call, the caller can be resolved by the caller's frustration due to the unanswered caller by guiding the reason and time of the call. In addition, the caller can be notified of the remaining time of the subscriber's unavailable call so that the call can be retried after the deadline expires, and the called party can be notified of the incoming call so that the called party can selectively attempt to return the call.

In addition, the non-call guidance service can be easily activated and registered by a number, a symbol, or a short code consisting of numbers and symbols, so that when a situation occurs in which an incoming call cannot be answered, the call can be easily blocked anytime and anywhere. .
