Abstract

PURPOSE: A method for refusing a destination request from an anonymous calling subscriber is provided to refuse the termination requested in the state that it is difficult to display a calling subscriber's information. CONSTITUTION: A CC(Call Control) part in a called side exchange sends a termination seizure notification signal to inform a calling side exchange that a termination seizure request signal has been received(301). If a switch-connected notification signal is received from the calling side exchange, the CC part of the called side exchange checks whether the called subscriber terminal is registered in CID(Call Identity Delivery) service(303). If the called subscriber terminal is registered in CID service, the CC part of the called side exchange checks whether the received termination seizure request signal contains a CID prevention request signal(305). If the received termination seizure request signal contains the CID prevention request signal, the CC part of the called side exchange checks whether the called subscriber terminal is registered in anonymous telephone receiving refusal service(307). If the called subscriber terminal is registered in anonymous telephone receiving refusal service, the CC part of the called side exchange sends destination refusal announcement to the calling side exchange(309).

Description

How to reject an incoming call from an anonymous outgoing subscriber {METHOD FOR REJECTING TERMINATING CALL REQUEST OF ANONYMOUS CALLING PARTY}

The present invention relates to a method for rejecting an incoming request from an anonymous outgoing subscriber. In particular, the present invention relates to a method for rejecting an incoming call request from an incoming subscriber having an information display function of an outgoing subscriber. The present invention relates to a method for rejecting an incoming call of an anonymous caller who refuses.

As the telecommunications market opens up, the competition is intensifying, and efforts are being made to improve the quality of telecommunication services for subscribers. The information display function of the calling subscriber is one of the products according to the above-mentioned trend.

Currently, the calling subscriber information display function is called when the called party subscriber is a caller ID service (CID) service registration subscriber, regardless of the terminal type of the calling subscriber and the relay line signaling method of the exchange period. It is implemented by collecting the information of the subscriber and displaying it so that the called party can recognize it. At this time, the collection method for the outgoing subscriber information, receiving and processing the information transmitted together with the incoming exchange request at the calling exchange, or requesting the transmission of the outgoing subscriber information corresponding to the calling exchange at the called exchange to receive it There is a way.

However, there may occur a case where the calling party information is not included in the called party's request signal as described above, and the information of the calling party is not provided from the calling party exchange despite the request from the called party's exchange. In the same case, there is a tendency that the incoming subscriber is difficult to determine whether or not the incoming subscriber is called as the incoming call is required. That is, when the called party is requested while the calling party information is displayed, the called party sees the information of the calling party that is displayed and decides whether to receive the call. If the called party is requested without the information of the calling party, the calling party information is displayed. In the same way as a regular telephone that does not provide a function, it is impossible to know at all about the calling subscriber.

The present invention has been made in view of the above-described disadvantages, and an object thereof is to provide a method for rejecting an incoming call request of an anonymous caller for rejecting an incoming call required in a difficult state of displaying information on the calling party.

In order to achieve the above object, the method according to the present invention, when the incoming call occupancy is requested from any calling subscriber, the call processing method for displaying the information of the calling subscriber through a dedicated display terminal provided separately from the terminal of the called subscriber. In the case of a call attempt, if the subscriber requests the incoming subscriber information indication or the registered subscriber to the outgoing subscriber information display prevention service requests the incoming subscriber as the called subscriber, the called subscriber is the registered subscriber information display function service. Checking the first step; A second check step of checking whether the incoming subscriber information display prevention request signal is included in the incoming occupancy request signal if the called subscriber is the subscriber registration information service registration subscriber: a result of performing the second check step, A third checking step of checking if the called subscriber is a registered subscriber to the anonymous call rejection service; As a result of performing the third check step, if the called subscriber is a subscriber registered in the anonymous call rejection service, the call reception announcement announcement is transmitted to the subscriber, and the termination of the incoming call processing to the called subscriber is performed. .

1 is a schematic functional block diagram of a system for performing a method for rejecting an incoming call request of an anonymous caller according to the present invention, comprising: a calling party terminal 102, a calling party exchange 110, a called party exchange 120; It consists of the called party's subscriber terminal 130 and the display terminal 135.

The calling party's terminal 102 may be applied regardless of whether it is an analog terminal such as a Public Switched Telephone Network (PSTN) or a digital terminal such as an Integrated Services Digital Network (ISDN) terminal.

The originating exchange 110 may also be referred to as a subscriber matching section 111, a number translation section (also called Number TRanslation, NTR) 112, a call processing section 113, a database 114, a trunk line matching section (Trunk Interface, TI). 115).

The subscriber matching unit 111 is provided to have a structure suitable for the type of the calling party subscriber terminal 102. For example, when the calling party subscriber terminal 102 is an analog terminal, it is provided with an analog subscriber interface board (abbreviated as ASI) 111 and, in the case of a digital terminal, a digital subscriber configured to accommodate the same. It is provided with a matching part (Digital Subscriber Interface). The number translation unit 112 performs translation processing on the data transmitted from the subscriber matching unit 111 and the call processing unit 113, and the call processing unit 113 receives a subscriber housed in the originating exchange 110. To control the overall function in the source exchange 110 to enable the call with the subscriber requesting the request, the database 114 stores / manages information about the subscriber accommodated in the source exchange 110, and relay line matching The unit 115 performs a matching process so as to be able to communicate with a server of a large power station such as the called party exchanger 120 or a service provider not shown.

The destination side exchange 120 includes a relay line matching unit 121, a number translation unit 122, a call processing unit (also called a Calling Control (CC)) 123, a database 124, a digital subscriber interface (Digital Subscriber Interface), 125), and a terminal matching unit 126.

The relay line matching unit 121, the number translation unit 122, the call processing unit 123, and the database 124 are the relay line matching unit 115, the number translation unit 112, and the call processing unit in the originating exchange 110. 113), and serves as the same dimension as the database 114, the digital subscriber matching unit 125 is configured to perform an electrical matching process with the destination subscriber station 130, the terminal matching unit 126 is displayed And an electrical matching process with the user terminal 135.

The display terminal 135 is dedicated to the called party's subscriber terminal 130. When the outgoing subscriber information transmitted from the terminal matching unit 126 is received, the display terminal 135 performs frequency modulation by FSK (Frequency Shift Keying). (Not shown) and a display unit (not shown) for displaying outgoing subscriber information modulated and transmitted by a frequency modulator (not shown).

2 is a flowchart illustrating an operation of the calling party exchange 110 in the method of rejecting an incoming call of an anonymous caller according to the present invention, and FIG. 3 is a call side exchange 120 of the call request rejection method of an anonymous caller according to the present invention. ) Is a flow chart.

1 to 3, the operation of the embodiment according to the present invention will be described.

When the calling party terminal 102 attempts to make a call to the called party subscriber terminal 130, the subscriber matching unit 111 transmits the digit information received from the calling party subscriber terminal 102 to the number translation unit 112. do. The number translation unit 112 transmits the translation result for the authorized digit information to the call processing unit 113 (step 201).

When the translation result is transmitted from the number translation unit 112, the call processing unit 113 proceeds to step 202, analyzes the received translation result, and receives the request information for preventing the display of the outgoing subscriber information from the calling party terminal 102. Check it. As a result of the check, if the calling party information display prevention request information is not authorized from the calling party terminal terminal 102, the calling party subscriber is referred to the database 114 using the translated calling party's telephone number. Check whether the subscriber is registered in the outgoing subscriber information prevention service. As a result of the check, if the corresponding originating subscriber is not the subscriber registered in the above-described service, the flow proceeds to step 204 to perform an existing call processing routine so as to make a call with the called party's terminal 130.

However, as a result of checking in step 202, an outgoing subscriber information display prevention request signal has been applied from the calling party subscriber terminal 102, or as a result of checking in step 203, the calling party subscriber terminal 102 registers an outgoing subscriber information preventing service registration subscriber. In step 205, the call occupancy request signal carrying the caller ID information prevention request signal is transmitted to the corresponding call destination switch 120 through the relay line matching unit 115.

Then, when the incoming occupancy notification is received from the destination exchange 120 in step 206, in step 207, a switch in the source exchange 110 is connected to the originating exchange 110 for the calling party subscriber terminal 102. Form a currency path. After the call path is formed, the call processing unit 113 proceeds to step 208 to notify the destination side switch 120 of the switch connection, and proceeds to step 209 to maintain the standby state for the incoming response.

At this time, when the reception rejection announcement is received from the destination side exchange 120, the call processing unit 113 proceeds from step 210 to step 211 and notifies the calling party subscriber terminal 102 that the reception rejection announcement is received, Return to next step. Here, in the next step, the subscriber terminal 102 may be controlled by the subscriber in a hook-on state, thereby releasing the switch connection in the originating exchange 110, or a routine requesting an incoming call may be performed again.

On the other hand, when the receiving side request signal is received from the calling side exchange 110 through the relay line matching unit 121, the called side exchange 120 translates the telephone number of the subscriber requested to the number translation unit 122 The translation result is transmitted to the call processing unit 123. The call processor 123 analyzes the received translation result and checks whether the called party is a subscriber accommodated in the called side exchange 120. As a result of the check, in the case where the subscriber is accommodated in the destination exchange 120, the call processing unit 123 informs the originating exchange 110 to receive the incoming occupancy request signal through the relay line matching unit 121 in step 301. Send the incoming call notification signal.

Accordingly, the call processing unit 113 in the originating exchange 110 performs switch connection processing for the originating subscriber terminal 102 in the originating exchange 110 as described above, and when the execution is completed, relay line matching Notifying the called party exchange 120 through the unit 115.

When the call processing unit 123 in the called side exchange 120 receives a switch connection notification from the calling side exchange 110 in step 302, the process proceeds to step 303 where the called party subscriber terminal 130 displays the caller information. Delivery, hereinafter abbreviated as CID) Check if the service is registered subscriber. This is done with reference to subscriber information stored in database 124. As a result of the check, if the corresponding called party is not the CID service registered subscriber, the flow proceeds to step 304 to perform a general call processing routine. That is, the digital subscriber matching unit 125 transmits a ring indicating the incoming request to the called party's subscriber terminal 130, and when the called party's subscriber terminal 130 responds to the sent ring, it forms a called party's call path. Make a call with the calling party terminal 102.

However, if it is checked in step 303 that the corresponding called subscriber is a CID service registered subscriber, the flow proceeds to step 305 to check whether the incoming caller request display prevention request signal is carried in the received call occupancy request signal. As a result of the check, if the incoming call occupancy request signal does not contain the calling subscriber information display prevention request signal, the flow proceeds to step 306 to perform information collection and display processing routine for the calling party subscriber terminal 102.

The information collection and display method of the calling party subscriber terminal 102 checks whether information of the calling party corresponding to the received call occupancy request signal is loaded, and if the information of the calling party is loaded, the terminal matching unit 126. ) And to display on the display terminal 135, and if the information of the calling subscriber corresponding to the incoming occupancy request signal is not loaded, request and send the information of the calling subscriber to the calling exchange 110 It is displayed on the display terminal 135 through the terminal matching unit 126.

As a result of checking in step 305, if the incoming call occupancy request signal includes the call out subscriber information display prevention request signal, the call processing unit 123 proceeds to step 307 where the corresponding called party subscriber terminal 130 registers the anonymous call rejection service. Check if you are a subscriber. The check is made with reference to the subscriber information stored in the database 124.

As a result of the check, if the corresponding called party is not the anonymous call rejection service registered subscriber, the flow proceeds to step 308 to perform the outgoing subscriber information display prevention routine. That is, the call processing unit 123 activates the display function of the outgoing subscriber information for the call, and displays the display terminal 135 through the terminal matching unit 126 according to whether the called party's subscriber terminal 130 is currently in a call. Send and display the reason message for not displaying the outgoing subscriber information.

However, as a result of checking in step 307, if the called party subscriber terminal 130 is an anonymous call rejection service registered subscriber, the call processing unit 123 proceeds to step 309 so that the call reject announcement is sent to the calling exchange 110. The flow proceeds to step 310 where the incoming call processing for the called party subscriber terminal 130 is terminated. Accordingly, no notification is made to the called party's subscriber terminal 130 according to the incoming request of the calling party's terminal 102.

As described above, the present invention is a subscriber terminal having a function for displaying the calling subscriber information, sending a call rejection announcement to the calling subscriber corresponding to the case where an incoming call is requested from an anonymous calling subscriber. The call request to the terminal provides a method of rejecting an incoming call request of an anonymous caller who stops, thereby facilitating the determination of the callee's reception and reducing the scope of the call to determine the call.
