Description

CID system capable to the image transmission and controlling method therefore}

The present invention relates to a CD system capable of transmitting an image and a control method thereof, and in particular, when a SMS has a traffic call channel, an image transmission capable of transmitting an image specified by the sender together with CID information is also transmitted. A system and a control method thereof.

In general, as the industrial society develops, information communication systems are widely used to transfer data from one point to another desired more appropriately and quickly. Such communication systems are usually homogeneous or heterogeneous communication devices which are geographically dispersed. In most cases, information devices are connected to a network to enable sharing and communication of resources.

For example, a telephone system via an exchange or a connection between a terminal and a server of a financial institution such as a bank is widely used. Recently, however, such communication devices, particularly telephone systems, have a built-in CID (Calling Identity Delivery) function that delivers the caller's information, for example, the caller's phone number, the date / time the call was made and other information. In addition, such CID information is usually modulated by a frequency shifting scheme (FSK) and received after the first ring signal.

Then, referring to FIG. 1 of the telephone system with the above-described CID service function, the CID modem for receiving the CID information transmitted through the transmission line 72 from the CID data block 71 of the exchange 70 ( 73), a controller 75 which controls the CID information input from the CID modem 73, displays it on the LCD panel 74, and controls the overall functions of the telephone system; and call control of the controller 75. It consists of a call circuit section 76 for executing a phone call with the other party's caller via the transmission line 72 in accordance with the signal.

On the other hand, referring to the operation of the telephone system with a built-in CID service function, when the caller at a certain position makes a phone call 79, the telephone system is called via the switches 70 and 77 in a normal manner. The ring signal is input to the call circuit section 76 at (78). At this time, the CID data transmission block 71 of the switch 70 connected to the called telephone system 78 side calls the CID information of the caller between the first ring signal and the second ring signal, that is, the caller's telephone number or the date of the call. / Time and other information is carried to the CID modem 73 of the telephone system 78. Then, the CID modem 73 modulates the caller's CID information by the FSK method according to the control signal of the controller 75 to process a predetermined signal and then displays it on the LCD panel 74. Accordingly, on the LCD panel 74, the caller's telephone number of the other party's caller, the date / time of the call, and other information are displayed as text or numeric signals according to the CID information. Thus, the subscriber can confirm the caller's information displayed on this LCD panel 74.

In addition, when there is a telephone call from the outside when the telephone system 78 is busy, the CID data transmission block 71 of the switching system 78 transmits a specific tone through the transmission line 72 where the current circuit is formed. (Tone) signal is sent. Then, the CID modem 73 recognizes the specific tone signal according to the control signal of the controller 75 and transmits the recognition signal to the CID data transmission block 71. Then, the CID data transmission block 71 transmits the CID information of the caller who is currently busy during the call to the CID modem 73. Then, the CID modem 73 modulates the caller's CID information by the FSK method according to the control signal of the controller 75 to process a predetermined signal and then displays it on the LCD panel 74. Therefore, on the LCD panel 74, the phone number of the counterpart caller, the date / time of the call, and other information are displayed as text or numeric signals according to the CID information. Therefore, the subscriber checks the caller's information displayed on the LCD panel 74 and takes appropriate measures even during the call.

In addition, the CID service as described above is executed in the mobile communication terminal. When a call signal is transmitted from the mobile communication terminal 80 to the PSTN network as shown in FIG. 2, the call signal is transmitted to the VLR via the base station 81. (Visitor Location Register) is input to the MSC 82 provided. Accordingly, the MSC 82 converts the corresponding calling terminal information provided from the authentication center 83 equipped with the HLR (Home Location Register) according to the call signal, and the switch 84 of the corresponding PSTN network converts the information into a CID signal. To the phone 85. Then, the phone 85 demodulates it using an internal CID modem (not shown) and displays it on the LCD, thereby executing the caller ID service bus.

However, the telephone or mobile communication terminal that executes the conventional CID service as described above can transmit general traffic data or CID information, but the user cannot transmit image data that he / she wants to transmit at his convenience. Convenience has been considerably reduced, and if the image data is transmitted together with the CID data as described above, an expensive additional device needs to be installed, thereby causing a problem of significantly increasing the maintainability of the CID system.

Accordingly, the present invention has been invented to solve the conventional problems as described above, the sender can transmit different image information according to the receiving party, according to the CD system capable of image transmission to maximize the ease of use of the CID terminal and accordingly The purpose is to provide a control method.

Another object of the present invention is to provide a CD system and a control method capable of image transmission, which can realize an image transmission function without providing additional special configuration means, thereby significantly improving the functionality of the CID terminal.

According to an aspect of the present invention, a PSTN network switch interoperating with a mobile communication system receives and processes CID information and image information received through an SMS traffic call channel from a PSTN network switch capable of CID processing. An FSK modem, a memory unit for storing CID information and image information processed by the FSK modem, a CID information and image information processed by the FSK modem are controlled and displayed on the LCD panel, and the overall function of the telephone system is controlled. Provided is a CD system capable of transmitting an image including a control unit for controlling and a control method thereof.
