Description

How to display calling party number and name {METHOD FOR DISPLAY A DIRECT NUMBER AND NAME FOR CALLING PARTY}

The present invention relates to a method of displaying a calling party number and name, and more particularly, a telephone number (also referred to as a direct number, DN) and a name of a calling party requesting an incoming call regardless of the type of subscriber and whether the called party is in a call. The present invention relates to a calling party number and a name displaying method.

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.

However, the currently proposed calling subscriber information display function can provide only the calling subscriber's telephone number for the ISDN subscriber station accommodated in the ISDN exchange where the relay line signaling method is an ISUP (ISDN User Part). It is enough. That is, a function for displaying only the telephone number of the calling subscriber is provided in a call environment in which the calling and receiving subscriber terminals are all ISDN subscriber terminals. This is because the telephone number of the calling subscriber can be transmitted using the ISUP signaling method. ISUP signal type is no. 7 This is an inter-station signaling method implemented by common line signaling method and provides the function to control various line control and additional services of ISDN.

Accordingly, the proposed method is not only able to provide the outgoing subscriber information display service in the call environment where the inter-station signaling method is not implemented with ISUP signaling and the type of subscriber station is not an ISDN terminal. Even if the environment satisfies the environment, the outgoing subscriber information provided is limited to the phone number.

The present invention has been made to solve the above-mentioned disadvantages, and provides an outgoing subscriber's telephone number and name display method that can display the calling party's telephone number and name so that the called party can recognize in any call environment. There is this.

Another object of the present invention is to provide a calling party number and a name displaying method for displaying a calling party's telephone number and name for the called party to recognize the called party regardless of whether the called party is in a call. .

In order to achieve the above object, a method according to the present invention comprises: a first checking step of checking whether a called party is a calling party information display function registered service subscriber when any calling party requests incoming call occupancy to any called party; As a result of performing the first checking step, if any called party is a calling party information display function registered service subscriber, obtaining a calling party's telephone number; A second checking step of checking whether any called party is an outgoing subscriber name display function registered subscriber when the calling party's telephone number is obtained; As a result of performing the second check step, if the calling subscriber name display function is registered as a subscriber, searching for a name of an arbitrary calling subscriber by accessing a server holding the subscriber name through a data network; A third checking step of checking whether a called party is busy by receiving a search step performing result; As a result of performing the third check step, if the called party is not in a busy state, after the initial ring is sent to the terminal of any called party, it is randomly placed on the display terminal dedicated to the called party provided separately from the terminal of any called party. Displaying together with the calling subscriber's telephone number and a search result performing result; As a result of performing the third check step, if the called party is in a busy state, the call channel is temporarily blocked, and the calling channel is displayed on the display terminal together with the calling party's telephone number and the search result, and then the call channel is restored. It is characterized by including.

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

1 is a schematic functional block diagram of a system for performing a method for displaying an outgoing subscriber's telephone number and name according to the present invention, the calling side exchange 100, the called side exchange 110, the data network 120, name data. It consists of a base (DataBase, abbreviated as DB) server 130, the called party subscriber terminal 140 and the display terminal 150.

When the calling party exchange 100 translates the phone number of the subscriber who requested the incoming call to any subscriber, the corresponding subscriber is the called party's terminal 120 accommodated in the called party's exchange 110. If a caller is requested to the destination exchange 110, and a phone number for any of the above-described subscribers corresponding to the calling party subscriber from the destination exchange 110 is requested, the phone number for any subscriber is called. It has a function that can be sent to the side exchange 110.

The destination exchange 110 is a trunk line matching unit (also called a trunk interface (TI)) 111, a number translation unit (also called Number TRanslation, NTR) 112, a call control unit (also called digital calling control, DCC) 113 ), A common database 114, a User Part Control (hereinafter referred to as UPC) 115, a Digital Subscriber Interface (DSI) 116, and a terminal matcher 117. It is composed.

The relay line matching unit 111 is configured to perform a matching process for communication with the power station (the originating exchange 100 in FIG. 1) or the data network 120 as before, and the number translation unit 112 is the relay line matching unit. 111 or the call control unit 113 is configured to perform number translation, the call control unit 113 is a call control performed in the existing ISDN exchange when the destination exchange is an ISDN exchange and according to the present invention Configured to perform call control for the originating subscriber's telephone number and name indication service, and the common database 114 is configured to store information for all subscribers accommodated at the destination exchange 110, and the UPC 115 ) Is used to perform the user signaling function used in the data exchange, and is used when access to the name DB server 130 is required, and the digital subscriber matching unit 116 is accommodated by the destination exchange 110. Is configured to perform the called party subscriber terminal 140 and the electrical mating process, the terminal matching unit 117 is configured to perform the terminal 150 and electrical matching processing for the display.

The display terminal 150 is dedicated to the called party subscriber terminal 140. When the outgoing subscriber information transmitted from the terminal matching unit 117 is received, the display terminal 150 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 a method of displaying a calling party's telephone number and name according to the present invention. Referring to FIG. 1, an operation flowchart illustrated in FIG. 2 will be described.

First, when an incoming call to the called party subscriber terminal 120 is requested from any subscriber accommodated in the calling party exchange 100, the calling party exchange 100 translates the number of the called party as before. According to the number translation result, the destination occupancy request signal is sent to the destination exchange 110.

When the incoming exchange request signal is received from the originating exchange 100 through the relay line matching unit 111, the called side exchange 110 requests a translation to the number translator 112 for the telephone number of the subscriber who is requested to be received. It checks whether or not the subscriber is requested that the incoming call is accepted by the destination side exchange (110). As a result of the check, in the case of the subscriber accommodated in the destination side exchange 110, the number translation unit 112 transmits the incoming occupancy request signal to the call control unit 113.

Accordingly, the call control unit 113 proceeds to step 201 and checks whether the incoming subscriber who is currently required to occupy the incoming call is a subscriber of call identity delivery (CID). This is done with reference to the subscriber information stored in the common database 114. If it is determined that the called party is not a CID service registered subscriber, the process proceeds to step 202 to perform a general call processing routine. That is, the digital subscriber matching unit 116 transmits a ring indicating the incoming request to the called party's subscriber terminal 140, and when the called party's subscriber terminal 140 responds to the sent ring, a called party's call path is formed. Make a call with the calling subscriber.

However, as a result of checking in step 201, if the corresponding called party is a CID service registered subscriber, the process proceeds to step 203, where the calling party acquires the calling party. Calling number acquisition processing checks whether there is a calling number in the incoming call occupancy request signal, and if the calling number does not exist, requesting the calling number to the calling side exchange 100 through the relay line matching unit 111. Get in the way.

If the corresponding call number is obtained, the call control unit 113 proceeds to step 204 to check whether the corresponding called party is a subscriber registered in the calling subscriber name display function service. As a result of the check, if the subscriber is not registered in the calling party name display function service, the flow proceeds to step 205 to perform a routine of displaying only the telephone numbers of the calling subscribers obtained. That is, regardless of whether the called party's subscriber terminal 140 is in a call, the terminal matching unit 117 processes only the phone number of the calling subscriber corresponding to the display terminal 150 to be displayed.

However, if the check result of step 204 indicates that the called party is the subscriber of the calling subscriber name display function, the call controller 113 proceeds to step 206 and the name query request message of the calling subscriber corresponding to the user unit controller 115 is performed. And proceeds to step 207 to drive the timer for the name lookup request message.

The user unit controller 115 accesses the name DB server 130 through the data network 120 and transmits a message to the relay line matching unit 111 that can search for the name of the corresponding calling subscriber. The received relay line matching unit 111 requests a name inquiry for the calling subscriber corresponding to the name DB server 130 through the data network 120.

The name DB server 130 searches for the name of the corresponding caller by using the corresponding calling party's telephone number, and if the name of the corresponding calling party exists, to the called party exchange 110 through the data network 120. If the sender name does not exist, but the sender name does not exist, an error message is sent to the destination exchange 110 through the data network 120. As described above, the transmitted error message indicates that the caller name does not exist when the caller name does not exist in the name DB server 130. In addition, even when a normal search result is not obtained due to an error of the name DB server 130 itself or an error on the data network 120 and the relay line matching unit 111, the destination side exchange 110 receives an error according to the caller name search request. It can be implemented to receive messages.

On the other hand, the call control unit 113 proceeds from step 207 to step 208 to check whether a timeout for the name lookup request has occurred. If no timeout has occurred, the process proceeds to step 209 to check whether a normal inquiry result has been received. However, if the timeout occurs in the check in step 208 or the normal check result is not received in the check in step 209, the process proceeds to step 210 and receives and stores the requested check result as an error message.

If the check result in step 209 indicates that a normal inquiry result (name of the corresponding calling subscriber) is received or the caller name inquiry result is received as an error message in step 210, the call control unit 113 proceeds to step 211 and the call is currently received. Check if the subscriber is busy. As a result of the check, if the call is not in a busy state, the process proceeds to step 212 and transmits an initial ring to the destination subscriber station 140 through the digital subscriber matching unit 116. The process proceeds to step 213 to send out the caller's telephone number (DN) and name (or the error message received in step 210), proceeds to step 214 to send out a normal ring, and then proceeds to step 215. You are returned to the next step for the call.

On the other hand, if it is checked in step 211 that if the called party's terminal 140 is busy, the process proceeds to step 216 where it temporarily blocks the call channel between the calling subscriber and the called party's terminal 140, and proceeds to step 217. In progress, the sender's telephone number (DN) and name (or an error message) are transmitted to the display terminal 150 through the terminal matching unit 117 for display. In step 218, the call channel between the calling subscriber and the called party subscriber terminal 140, which has been in a call, is restored.

As described above, the present invention provides a separate display exclusively for the called party subscriber, regardless of the type of the subscriber station, the inter-station signaling method, and whether the called party is calling. By implementing the output through the terminal, there is an advantage that can extend the service range for the information display function of the calling subscriber.
