Abstract

PURPOSE: An absent subscriber automatic response service method in an intelligent network is provided to implement an automatic response function through a generic telephone by using the greeting service function of an intelligent network. CONSTITUTION: If a calling terminal inputs the DN(Directory Number) of a called terminal, the inputted DN is transmitted to the first exchange(202). The first exchange searches a subscriber database for called subscriber information using the transmitted DN and judges whether the called subscriber is an automatic response service subscriber(204). In case that the called subscriber is an automatic response service subscriber, the first exchange informs a service control point through a common channel signaling network that the called terminal has joined the automatic response service(208). In response to it, the service control point makes an intelligent network service part connected to the first exchange through the common channel signaling network(210). Also the service control point provides a call setup instruction signal to the first exchange. The first exchange creates a call setup signal according to the call setup instruction signal. As the call setup signal connects the first exchange with the second exchange, in which the called terminal is located, a call path is formed between the calling terminal and the called terminal(212).

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

1 is a block diagram of an IN system suitable for an automatic subscriber answering service according to the present invention, and includes a plurality of terminals connected to the IN 100.

The IN (100) is a transport switching network (110) consisting of a plurality of exchanges (112, 114), and a voice signal occupying a call path connected to the transport switching network 110 and route information for controlling the path to the call path, respectively The common line signal network 130 for separating and processing, the service controller 150 connected to the common line signal network 130 to process a call setup signal, and the message such as voice through the communication path to the transport switching network 110 An intelligent network service unit 160 capable of performing a service is provided.

The first switch 112 in the transport switching network 110 receives a directory number (hereinafter abbreviated as DN) input from an originating terminal connected thereto, and is connected to the second switch 114 corresponding to the received DN. It is searched from the subscriber database (not shown) whether the subscriber of the called terminal is subscribed to the IN 100 or other service requiring the network. As a result of the search, if the subscriber of the terminating terminal is not subscribed to the service requiring the IN 100 or other network, the first exchange 112 establishes a call and the terminating terminal and the second exchange 114 according to the call setup. Connect the call path of the calling terminal connected to the call to be made.

However, as a result of the search, when the subscriber of the called terminal is a subscriber absent auto answer service subscriber requiring the IN 100, the first switch 112 receives the service controller 150 through the common line signaling network 130. The terminal reports that it is subscribed to the subscriber absent answering service.

The service controller 150 receives a report from the transmission switching network 110 that the called terminal is subscribed to the subscriber absent auto answer service and transmits a command to the intelligent network service unit 160 to wait for a guide broadcast connection to the calling terminal. Instructs first switch 112 with the originating terminal to establish a call.

Accordingly, the first switch 112 sets up a call according to a call setup command from the service controller 150 and connects the call path with the second switch 114 having the called terminal according to the call setup. In a state in which the call path between the first and second exchangers 112 and 114 is connected, when it is confirmed that the called terminal is not hooked off after a certain time, the originating terminal of the first exchange 112 and the second exchange 114 are checked. The call path of the transport switching network 110 connected to the destination terminal of the intelligent network service unit 160 is connected.

When the intelligent network service unit 160 is connected to the calling terminal and the called terminal while waiting according to a command to connect the announcement broadcast from the service controller 150 through the common line signal network 130, recording, listening, Initiate announcement to guide deletion. When the message is recorded and terminated from the calling terminal, the second terminal 114 informs the called terminal that the message has been recorded in the area of the called subscriber of the intelligent network service unit 160. If the message is listening, the calling subscriber sends the message. When the message is deleted, the message stored in the area of the called subscriber of the intelligent network service unit 160 is deleted.

Referring to Figure 2, it will be described in detail the steps of the automatic subscriber response service.

First, in step 202, the digitized DN is transmitted to the first exchange 112 in the transport switching network 110 by digitizing the DN of the called terminal at the originating terminal.

The first exchange 112 retrieves subscriber information of the called terminal from the subscriber database using the transmitted DN to determine whether the subscriber of the called terminal is an auto-responder service subscriber (step 204). In step 204, if it is determined that the called terminal is not subscribed to the auto answering service, the call is connected to the called terminal according to the transmission DN and terminated (step 206).

However, if it is determined in step 204 that the called terminal is subscribed to the answering machine service, as in step 208, the first switch 112 shares the information indicating that the called terminal is subscribed to the answering machine service. Provided to the service controller 150 through the signal network 130.

In a next step 210, the service controller 150 responds to the information indicating that the called terminal provided through the common line signal network 130 from the first exchange 112 is subscribed to the auto answer service, and the common line. The intelligent network service unit 160 is connected to the first switch 112 through the signal network 130. In addition, the service controller 150 generates a signal instructing the first switch 112 to set up a call so that the first switch 112 sets up a call according to the subscriber absent auto answer service of the called terminal.

In step 212, the first exchange 112 generates a call setup signal with routing information according to the signal instructing the call controller to set up the call. The call setup signal generated by the first switch 112 connects the call path with the second switch 114 having the called terminal to form a call path between the calling terminal and the called terminal.

In step 214, the first exchange 112 determines whether the called terminal has been hooked off for a certain time. If it is determined that the called terminal is hooked off, the process proceeds to step 216 where a call between the calling terminal and the called terminal proceeds through the connected call path, otherwise, the process proceeds to step 218.

In step 218, the service controller 150 instructs the intelligent network service unit 160 to start the announcement broadcast to the calling terminal through the transport switching network 110 connecting the call path of the calling terminal and the called terminal, the intelligent network service Announcement broadcast is connected between the unit 160 and the calling terminal. For example, the configuration of the announcement broadcast broadcasts a message previously recorded by the subscriber of the called terminal to the first half of the announcement broadcast within 2 minutes, and then to send out the voice provided by the intelligent network service unit 160 . The voice provided by the intelligent network service unit 160 is ″ beep ″ and then ″ 1 for recording the voice mailbox, 2 for listening to the recorded voice mailbox, and 3 for deleting the recorded voice mailbox. , And if you want to end the service, press the # or * mark. ″

Accordingly, one of ″ 1 ″, ″ 2 ″, ″ 3 ″, ″ # ″, and ″ * ″ is selected by the calling terminal subscriber who listens to the announcement broadcast provided by the intelligent network service unit 160, and the selected signal is the first signal. The switch 112 and the common line signal network 130 are transmitted to the intelligent network service unit 160 (step 220).

In step 216, if it is determined that the subscriber of the calling terminal has selected the message recording by pressing the code ″ 1 ″, the message input from the calling terminal under the control of the intelligent network service unit 160 is recorded in the intelligent network service unit 160. do. If it is determined that the subscriber of the calling terminal selects to listen to the message by pressing &quot; 2 &quot;, the message is recorded in the area allocated to the called terminal in the intelligent network service unit 160. Further, if it is determined that the subscriber of the calling terminal selects message deletion by pressing ″ 3 ″, the message recorded by the intelligent network service unit 160 in the area allocated to the destination terminal of the intelligent network service unit 160 is deleted. do. If it is determined that the subscriber of the calling terminal does not record, delete, or listen to a message in the answering machine by pressing ″ # ″ or ″ * ″, the call is terminated by connecting the busy tone to allow the subscriber of the calling terminal to hook on. Be sure to At this time, deleting the message and listening to the message are possible only when the password is input. That is, when the message listening code is input and when the message deletion code is input, the first exchange 112 requests the calling subscriber to call the subscriber when the password entered by the calling terminal subscriber is incorrect. The user will be prompted to play the business tone, and if the password is correct, the message will be listened to or deleted.

In the next step 222, when the recording, listening or deleting code of the message is input from the originating terminal to the intelligent network service unit 160 through the transport switching network 110 and the recording, listening or deleting of the message is finished, the intelligent network The service unit 160 announces the announcement that the message has been successfully recorded, listened to, or deleted to the calling terminal through the transmission switching network 110, for example, ″ The message has been successfully recorded / listened / deleted ″. To hook on the calling terminal and send a ring tone having a specific interruption sound to the called terminal to the called terminal to inform that the message has been recorded.

As described above, the present invention has the effect of receiving a simpler and more convenient answering service without the answering machine by using the function provided by IN.
