The present invention relates to a telephone terminal provided with a caller identification function (CID function), and more particularly, to a telephone terminal provided with a caller identification function up to a home wired telephone, a wired / wireless telephone, and a mobile phone which is a mobile communication terminal. Caller group in a telephone terminal provided with caller identification function that can identify callers using only the backlight emission color as well as the caller information displayed in text by displaying different backlight emission colors for caller groups classified by groups at the time of incoming call. The present invention relates to a star display method and a display device.

Recently, wired / wireless telecommunications operators have received a good response from subscribers by implementing a call-related additional service called "caller number display service". This caller ID display service is also commonly referred to as a "Caller ID" service, that is, a "CID" service. The CID service is based on the CCITT (Consultative Committee on International Telephone and Telegraphy), the current international Telecommunications Union-Telecommunication Standardization Sector (ITU-T) V.32 It is a service that provides the name of the (caller), a telephone number as a unique identification number, time information according to call origination and reception.

Currently, CID service is widely used in terms of the benefits of protecting the privacy of recipients in connection with phone calls, and the protection of call reception options through caller confirmation. Now, when a call is received through a wired or wired / wireless phone used at home, the caller information displayed on the display window can be checked and the phone call can be selected and the call window is displayed even when the call is received from a mobile phone. You can check the caller information that appears on the screened call.

On the other hand, individuals belong to various social organizations, not just one society. Individuals such as family members, school friends, company colleagues, and fellowships will inevitably or selectively participate in various societies. At this time, the members of the society exchange contact information for close contact with each other, and then contact each time necessary.

Consider this case in a telephone terminal. Here, it is assumed that the telephone terminal is a telephone terminal having a CID function. As mentioned earlier, individuals are involved in their various social organizations and are in close contact with each other. At this time, the most used one would be a telephone. For example, suppose a person named 'A' who joins a football club is waiting for a call from a football club officer to announce a football club meeting, but who may be ahead of the competition. Suppose that 'A' is currently chatting on the Internet to get football information at some distance from the phone. And, suppose that 'A' comes from a friend who wants to go to the casino at the same time as the match schedule of the football club. Suppose, of course, that 'A' is not interested in casinos, but focuses only on football matches.

Taken together, all the above assumptions suggest that 'A' is not interested in anything but a call to schedule a football club competition. In addition, you'll find that you don't want to answer your friends' phone to go to the casino.

In this case, assuming that an incoming bell or melody rings through a phone terminal providing a CID service, 'A' currently wants to answer the call selectively. You should check. To do this, 'A' moves to the position where the telephone terminal (home telephone or mobile phone), which is separated from its current position, is placed. After confirming the caller's telephone number displayed on the display window of the telephone terminal, the telephone number of the football club officer will receive the call, and if the telephone of the friend who goes to the casino will not answer the call. It doesn't matter if the incoming call is from a football club executive who's been waiting fortunately, but if the incoming call is from a friend who wants to go to the casino, 'A' doesn't answer the call, and he has to go back to chat. . However, 'A' had to stop chatting on the Internet to identify the caller and had to move to where the phone was located. This suggests an important point. That is, it is necessary to check from whom the call is received even from the telephone terminal. This would have the advantage of preventing unnecessary behavior for the telephone terminal user.

In another table group "B", the caller registered as a group member whose backlight emission color is "Green" and uses the backlight emission color as "green" at the time of incoming call is the first (02-1X2-3456). It can be seen that many of them are registered.

A registration procedure and a calling group sorting display function for registering the calling group sorting display function in order to sort and display the backlight emission color for each sender group according to a preferred embodiment of the present invention with reference to the drawings of FIGS. 1 to 7 described above. 8 and 9 will be described in detail with reference to FIGS. 8 and 9.

First, FIG. 8 is a diagram illustrating a registration procedure for registering a calling group sorting display function in order to sort and display a backlight emitting color for each sender group according to a preferred embodiment of the present invention. Look at the registration process;

Each of the telephone terminals exemplified in the present invention performs the standby mode in step 801, and in step 803, a user inputs a key input unit (or keypad: hereinafter described as a key input unit) provided in the telephone terminal. In step 805, if the calling group selection display function is selected using the key. In step 805, the controller (or central controller: described below by using a controller) of the telephone terminal provides a screen for registering a group name according to a set registration procedure, and displays the text provided in the key input unit from the user. Register by entering the group name through / numeric input keys. In step 807, the controller of the telephone terminal provides a screen for designating and registering a backlight emitting color for selectively displaying a calling group, and the backlight emitting color (the one through the key input of the key input unit) from the user. For example, red, green, blue, etc.) is input and registered. In operation 809, the controller of the telephone terminal receives and registers information (name and telephone number information) of group members (group members) by inputting text keys and numeric keys of the key input unit from the user. If there are a large number of group members, step 809 may be repeated to register each group member.

If the registration for the specific group is completed, the controller of the telephone terminal proceeds to step 811 and checks whether another group registration is selected. If another group registration is selected as a result of the inspection, the process returns to step 805 to sequentially repeat the subsequent process to register the name, backlight emission color, and group member information of another group to be registered.

When all registration is completed, the controller of the telephone terminal terminates the registration mode to perform the standby mode. If the call group selection display function is not selected in step 803 and another function is selected, the process proceeds to step 821 to perform the corresponding function.

If the backlight emission color of each group and the group member information according to the calling group sorting display function are registered and the corresponding function is set in the phone terminal, the CID information acknowledgment and the specific color of the group to which the corresponding CID belongs for all incoming calls Backlight emission of light is performed, which will be described in detail with reference to the flowchart of FIG. 9.

FIG. 9 is a flowchart illustrating a process of selecting and displaying different backlight emission colors for each caller group when an incoming call is notified according to an incoming call in a telephone terminal to which a calling group sorting display function is set according to an exemplary embodiment of the present invention.

In step 901, the controller of the telephone terminal performs the standby mode. If an incoming call is received in step 903, the controller proceeds to step 905.

In step 905, the controller of the telephone terminal checks whether there is CID information in the incoming call information. If there is CID information, the controller proceeds to step 909. If there is no CID information, the controller proceeds to step 907.

In step 907, the controller of the telephone terminal controls the incoming call notification mode to be operated. The incoming call notification mode transmits an incoming call ring (or melody) set to the outside through a speaker, and a normal backlight (normal). The backlight is preset registered.) For example, it emits a gray color to inform the user that there is an incoming call.

However, if there is CID information in step 905, the controller of the phone terminal searches for received CID information in step 909. In step 911, the controller of the telephone terminal determines whether the received CID information is CID information of a group registered in the calling group selection display function. If there is a group in which the received CID information is registered as a result of the inspection, the process proceeds to step 915, and if there is no group in which the received CID information is registered, the process proceeds to step 913.

In step 913, the controller of the phone terminal controls an operation of an incoming call notification mode for displaying CID information, and transmits an incoming call ring (or melody) to the outside through a speaker and sends the CID to a display window provided in the display unit. Information is displayed and a normal backlight color is emitted to inform the user that there is an incoming call.

However, if there is a group in which the CID information received in step 911 is registered, the controller of the telephone terminal proceeds to step 915 to search for the backlight emission color set in the registration group. As an example, when the received CID information is "01X-123-4567", the controller may determine that the CID information belongs to the group "A" from the registration table of the corresponding group stored in the memory as shown in the example of FIG. Search for Hong Gil-dong and search for backlight blue color.

When the emission color search is completed, the controller of the phone terminal proceeds to step 917 and controls the display to emit light of a specific backlight emission color indicating a group in which the CID information is registered through the display controller that controls the emission color of the backlight.

Then, in step 919, the controller of the phone terminal controls the operation of the call notification mode so that the display can be made by the calling group. The call notification mode uses the speaker to set the ringtone (or melody) set for the call. It transmits to the outside, displays CID information on the display window provided in a display part, and emits the specific backlight light emission color which shows the group in which the said CID information was registered.

Meanwhile, in the preferred embodiment of the present invention, the caller group is identified by changing the color of the LCD backlight, but the LCD backlight may be replaced with the LED to display the LED lighting color differently. In addition, different incoming bells or melodies that can be distinguished from each other may be generated together so that a telephone group can be identified audibly. In addition, in the detailed description of the present invention has been described with a specific embodiment, various modifications are possible without departing from the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention divides and registers callers in groups provided with a caller identification function, and then, by varying the backlight emission color corresponding to the group, to notify the incoming call even at a place separated from the phone terminal. There is an advantage that it is easy to check from whom the call was received without checking the caller information displayed on the display of the telephone terminal.

In addition, the present invention registers the caller information for each social group to which they belong, and when a call is received to the group members belonging to the group, it is possible to recognize from which group member the call originated without checking the display window of the telephone terminal. There is an advantage in that it is possible to check in a place remote from the phone terminal without having to check who came from the phone terminal to restrain unnecessary behavior and provide a more convenient service.
