CALL CONTROL APPARATUS AND OPERATION METHOD THEREOF}

The present invention relates to a call control device and a method of operation thereof, and more particularly, to connect a PSTN terminal to a user terminal connected to the Internet through the call control apparatus, and to the user terminal, telephone number management, remote dialing and a protocol. By installing software having a conversion function or the like, it is possible to make a telephone call through the VoIP telephone call on the PSTN terminal and the telephone number search on the user terminal. In the case of a telephone call, the calling party information including the CID in the user terminal. And a method of operating the same.

In general, most homes and businesses use public switched telephone network (PSTN) terminals for telephone calls. When using the PSTN terminal, the user searches for a means of recording and storing a telephone number such as a notebook or a mobile phone. The phone number was dialed by pressing the searched phone number with the terminal button, and the incoming call could be recognized only by a ring tone.

Looking at the usage form of the PSTN terminal, there was an inconvenience to search the phone book that is managed separately for each call, and there is a PSTN terminal that provides CID (Caller IDentifier) information, but the caller is only ringing or CID information at the time of incoming As it is not possible to know who the call originated, as in the case of call origination, the process of searching for the sender has been increased, and in case of outgoing calls from overseas or overseas, high costs were required as communication costs.

As an alternative to such a PSTN, a Voice over Internet Protocol (VoIP) has recently been proposed which can reduce communication costs by integrating a data communication network and a voice communication network. It is a telephone service that compresses signals and transmits them in the form of packets on a TCP / IP network such as the Internet or an enterprise intranet using a signaling protocol. Unlike PSTN, which is a circuit-switched telephone that requires continuous connection of circuits, multiple calls share the same network, which makes it possible to use resources efficiently.

So far, VoIP service has been used mainly by some companies. However, as the spread of high-speed Internet is active, it is desirable to introduce VoIP phone service in general homes or companies to reduce communication costs. In order to use the service, the following method or apparatus has been proposed and commercialized.

The first method is to install and use VoIP processing software on the user's computer, and install and use separate software that can use VoIP phone on the personal computer or laptop that most homes have, that is, using existing devices. The cost required was low.

There was a problem.

In addition, since the phone number management function is not provided, the inconvenience of having to search the phone book separately managed when the PSTN or the VoIP phone is received and received exists as it is. Since the PSTN terminal and the user computer capable of making and receiving the VoIP phone do not interwork with each other, Even if the software was given a VoIP phone number management function, the phone number management and retrieval could not be performed at the time of the incoming / outgoing call of the PSTN phone.

The second is the VoIP gateway, which is built as an independent system with internet access and VoIP call control, so even beginners can easily use PSTN and VoIP phones by connecting a computer and PSTN terminal to the gateway without installing any software. For this purpose, a separate gateway had to be provided, and the gateway was very expensive, which made it difficult to use universally.

The third is the Multimedia Terminal Adapter (MTA), which connects the Internet access device and the PSTN terminal to enable the VoIP telephone call from the PSTN terminal. However, it merely provides the telephone call function and provides the phone number management function and the display function of the calling party information. Since it does not provide, there is a problem in that the inconvenience of having to search for a phone book separately managed when an incoming / outgoing PSTN or VoIP phone exists.

The request signal is transmitted to the call management server 4 (S611).

The call management server 4 receiving the request signal searches for a phone number corresponding to the selected living information in the phone number information DB (S612) and makes a call to the searched phone number (S613) and the user terminal (1). In the case where the selected living information is advertisement information, the web service screen is displayed at the URL linked with the advertisement information through the display unit 13 together with the call connection. While the information displayed on the web service screen can be selected, the subsequent operation is the same as step S615.

4 is a control flowchart illustrating a call reception process through a call control apparatus according to the present invention. The display of the calling party information including the CID through the display unit 13 of the user terminal 1 at the time of the call reception ~ PSTN terminal ( We will explain in detail the incoming call process from 3) to the telephone call.

Referring to FIG. 4, the telephone call manager 16 of the user terminal 1 is the RING manager 26 of the call control device 2 connected to the PSTN trunk line or the user terminal 1 connected to the Internet. It continuously monitors the presence or absence of an incoming call signal transmitted from the VoIP processing unit 17 (S700).

If the incoming call detection signal is transmitted (S701) and the analysis result of the detection signal (S702) indicates that the ring signal is detected in the RING management unit 26 (that is, in the case of PSTN incoming call) (S703), the call The call manager 16 receives the CID (calling party number) information detected from the CID receiving unit 27 of the call control device 2 (S704a) and stores the phone number information DB stored in the phone number manager 15. The caller information (here, name) corresponding to the CID is retrieved (S705a), and the CID and the retrieved information are output to the pop-up window through the display unit 13 as shown in FIG. 5C (for example, " 016-2525-0001 ", and outputs a ring tone set to the calling party's telephone number through the input / output unit 14 (for example, a speaker) (S706a).

As described above, according to the ring tone setting information set in the phone number management unit 15, the PSTN terminal 3 does not ring, but various ringtones according to the calling party's telephone number ring only in the user terminal 1. Can be.

The continuous ring signal is not detected from the RING management unit 26 within a predetermined time, or the hook-off of the PSTN terminal 3 is detected from the HOOK detecting unit 24 of the call control device 2 (the user receives the receiver. When a signal indicating that the message has been received is transmitted (S707a), the telephone call manager 16 displays information (for example, "the user has picked up the handset" or "talk time 00:") included in the transmission signal in a pop-up window. 00 ") and stops the ring tone output through the input / output unit 14 to make a PSTN telephone call (S709a), and the telephone number manager 15 stores the calling party information and stores it in a recent incoming call list. · Be managed.

Here, if the hook signal is detected or the hook-off of the PSTN terminal 3 is not detected even after a predetermined time by enabling the forced control of the hook-on / off in the hook detection unit 24 (S707a, S708a) Make a hook-off state according to the instruction of the telephone call management unit 16, and transmit the pre-stored voice data to the caller side like the automatic answering function of the general telephone and the missed telephone number and the number in the pop-up window. Is preferably displayed (S711).

In addition, as in the case of the telephone call, the call time until the end of the call is continuously displayed through the pop-up window. The telephone call manager 16 continuously monitors the HOOK detector 24 of the call controller 2. When monitoring the end of the call (that is, the hook-on of the PSTN terminal 3) is detected (S710a), the total call time from the start of the call to the end of the call is stored and stored in the recent incoming call list of the phone number manager 15. To be managed.

If the analysis result of the detection signal in step S702 indicates that the VoIP call request message has been received by the VoIP processing unit 17 (that is, in case of a VoIP call reception) (S703), the telephone call managing unit 16 performs the VoIP processing unit. The telephone number of the calling party detected from 17 is received (S704b), and information corresponding to the calling party's telephone number in the telephone number information DB stored in the telephone number management unit 15 similarly to the PSTN incoming call (here, The name) and outputs the telephone number of the calling party and the retrieved information to the pop-up window through the display unit 13, and simultaneously through the input / output unit 14 (e.g., a speaker). The ringtone set in the number is output (S706b).

In addition, in step S706b, the telephone call manager 16 notifies the PSTN terminal 3 that the VoIP call has been received through the RING manager 26 of the call control device 2, and within the predetermined time, the VoIP processor ( If no continuous message is received from 17) or if a signal indicating that the hook-off of the PSTN terminal 3 is detected (the user has picked up the handset) is transmitted (S707b), the telephone call manager 16 pops up. VoIP telephone call by displaying the information (for example, "user picked up" or "talk time 00:00") included in the transmission signal in the window and stopping the ringing output through the input / output unit 14 (S709b), the phone number management unit 15 stores the calling party information to be stored and managed in the recent incoming call list.

The VoIP telephone call in the PSTN terminal 3 is made through the signal converter 28 of the VoIP processing unit 17 and the call control device 2, and the pop-up window is similar to the case of the PSTN incoming call. The call time until the end of the call is displayed continuously, the telephone call management unit 16 continuously monitors the HOOK detection unit 24 of the call control device 2 (that is, the PSTN terminal 3) Hook-On) (S710b) is stored in the recent incoming call list of the phone number management unit 15 by storing the total call time from the start of the call to the end of the call.

Here, as in the case of the PSTN incoming call, if a call request message is received after a predetermined time or the hook-off of the PSTN terminal 3 is not detected (S707b, S708b), the VoIP call management unit 16 instructs the VoIP call. The processor 17 transmits a callable message to the VoIP server 5 and connects the call, and then transmits the prestored voice data to the user terminal 1 like the automatic answering function of the general telephone. It is preferable to display the number and the number of times (S711).

As described above, the PSTN terminal is connected to a user terminal connected to the Internet through a call control device according to the present invention, and the user terminal is additionally installed by installing software having phone number management, remote dialing, and protocol conversion functions. With the simple network configuration using the existing equipment without the installation of equipment, VoIP telephone calls can be made from the PSTN terminal, greatly reducing installation and communication costs.

In addition, the remote telephone call is possible by searching the telephone number managed by the user terminal and selecting the telephone number through simple click, and the calling party information including the CID is displayed so that the user can be confirmed by the conventional telephone call. When an incoming and outgoing call was made, the cumbersome procedure and the time required to search a separate phone book could be shortened, thereby improving work efficiency when working with a computer.

In addition, the phone call screen and call screen are displayed in GUI form with high user access through the monitor, and the phone number can be input or selected with a simple click using an input device such as a mouse. It was easy to use even those who did not.

In addition, through the call management server, the telephone number management and telephone call function can be used on the web, and the data can be synchronized through the Internet so that the managed telephone number information DB and the telephone number information DB of the user terminal are kept the same. When the user selects the life information transmitted from the call management server, in particular, the advertisement information by one-click, the web service screen linked with the advertisement information is displayed at the same time as the call connection, so that the user can easily select by providing various additional services.
