DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, preferred embodiments according to the present invention will be described with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configuration incorporated herein are omitted to avoid making the subject matter of the present invention unclear.

FIG. 2 is a block diagram showing a construction of a communication terminal apparatus, which displays a function in communication, according to an embodiment of the present invention. Referring to FIG. 2, the communication terminal 100 according to an embodiment of the present invention includes a main processor 110, a display unit 120, an input unit 130, a memory 140, a speaker unit 150 and a communication interface unit 160.

The input unit 130 and the speaker unit 150 provide an interface between the communication terminal 100 and a user, and they are commonly included in general communication terminal apparatuses, such as a wire/wireless telephone or a portable telephone, together with a microphone unit (not shown). Accordingly, a detailed description regarding the input unit 130 and the speaker unit 150 is omitted.

The display unit 120 displays an operation state of the communication terminal 100 and an input item provided from a user, and particularly displays communication information when the communication terminal 100 is on line.

The communication interface unit 160 provides a communication interface between the communication terminal 100 and an outside network connection device (not shown). Herein, the outside network connection device supports a call service between a communication terminal apparatus and a network, such as a telephone exchange in a public switched telephone network and a base station in a mobile telephone network. A detailed description regarding the outside network connection device is omitted.

The memory 140 stores and manages operation information including basic operation information, additional function information and a function list in communication. Herein, the basic operation information are information for supporting a call service function which is an inherent function of the communication terminal 100. The additional function information are services, such as an alarm, a morning call or a telephone directory, which can be provided by the communication terminal 100 in addition to the call service function. The function list in communication is a list for items of functions (so-called “in-communication functions”) which can be selected and performed from among the additional functions while the communication terminal 100 is in communication. Herein, the function in communication may include a telephone directory, a transmission/reception volume control, a transmission sound interception (i.e. “mute”) and a key sound control, a transmission of self number, a call shift, a call holding, conference call, call recording, Dual Tone Multi-Frequency (DTMF), memo, etc. A transmission of self number is used to send the self number. DTMF is used to send the number inputted by the user as a DTMF tone signal. A call shift is used to connect an incoming call and hold with an current call.(i.e. shift between a current call and an incoming call). A call holding is used to hold a current call.

In order to perform such functions, the memory 140 includes a basic operation information storage 142 for storing and managing the basic operation information, an additional function information storage 144 for storing and managing the additional function information, and a function list in communication storage 146 for storing and managing the function list in communication.

The main processor 110 preferably controls the entire operation of the communication terminal 100. Particularly, when an operation mode of the communication terminal 100 changes from a communication waiting mode to a communication mode, the main processor 110 reads a menu (hereinafter, a menu in communication) capable of selecting the function in communication from the function list in communication storage 146 and displays the menu on the display unit 120.

Further, the main processor 110 may modify the function list in communication on the basis of an operation signal of a user inputted through the input unit 130. For instance, the main processor 110 deletes an item, which a user wants to delete, from among items included in a predetermined function list in communication, and the main processor 110 adds an item, which a user wants to add, to a predetermined function list in communication. Particularly, for additional modification of the function list in-communication, the main processor 110 reads an item, which can be added to the function list in communication, from the additional function information storage 144 and provides the item to a user.

FIG. 3 is a flowchart illustrating a display method of a function in communication of a communication terminal 100 according to an embodiment of the present invention. In the example in FIG. 3, a network connection device for supporting a call service between the communication terminal 100 and a network is shown as a base station (or an exchange) (hereinafter, referred to as a base station 200).

Referring to FIG. 3, when the communication terminal 100 having received a call request (S110) from the base station 200 responds with respect to the request (S120), a call-set up for calling is performed between the communication terminal 100 and the base station 200 (S130). Through steps S110 to S130, a general call-set up process was briefly described, but a call-set up process is not limited to the method exemplified in FIG. 3.

Next, when the call-set up is performed between the communication terminal 100 and the base station 200 through the aforementioned steps, an operation mode of the communication terminal 100 changes from a communication waiting mode to a communication mode. Then, the communication terminal 100 reads an already stored function list in communication from the function list in communication storage 146 in the memory 140 and then displays the list as a menu on the display unit 120 (S140). Herein, it is preferred that the function list in communication is displayed by a text type or an icon type.

Next, when a user selects a desired menu from among the function list in communication (S150), a function corresponding to the selection is performed (S160).

Also, the communication terminal 100 may enable the function list in communication to be displayed according to a predetermined display time. For instance, the function list in communication is displayed just after an operation mode of the communication terminal 100 changes to a communication mode, but the function list in communication is displayed during a predetermined display time. Herein, when information selected by a user is not inputted during the display time, the communication terminal 100 may enable the function list in communication to be deleted on a screen. Further, the communication terminal 100 may enable the function list in communication to be periodically displayed according to a predetermined display time interval.

Further, when a user does not want to display the function list in communication, the communication terminal 100 may be set according to information selected by a user so that the communication terminal 100 does not display the function list in communication even if an operation mode of the communication terminal 100 changes to a communication mode.

FIG. 4 is a flowchart illustrating a method for displaying a function in communication in a communication terminal apparatus according to an embodiment of the present invention. Referring to FIG. 4, the communication terminal 100 receives a call request message from an outside network connection device such as a base station or an exchange (S210) and responds with respect to the request (S220). As a result of the response, when a call-set up is performed between the communication terminal 100 and the outside network connection device (S230), an operation mode of the communication terminal 100 changes to a communication mode (S240). That is, the operation mode of the communication terminal 100 changes from a communication waiting mode to a communication mode. Then, the communication terminal 100 reads a function list in communication stored in advance from the memory 140 and displays the function list in communication (S250).

Further, when a user selects an item that the user wants to perform from the function list in communication_(S260), a function corresponding to the selection is performed (S270).

Further, though not shown in drawings, the communication terminal 100 can modify the function list in communication on the basis of request of a user. For instance, according to a user's command to add/delete the function list in communication, it is possible that a menu selected by the user is added to the function list in communication or a corresponding menu is deleted from the function list in communication.

FIGS. 5a and 5b are exemplary views regarding a screen in communication of a portable telephone according to an embodiment of the present invention. That is, FIGS. 5a and 5b show an example in which a function list in communication is displayed on a portable telephone in communication. FIG. 5a shows an example in which the function list in communication is displayed by a text type and FIG. 5b shows an example in which the function list in communication is displayed by an icon type.

In a method and communication terminal apparatus for displaying a function in communication according to the present invention, the function in communication is automatically informed to a user, thereby enabling a user to conveniently use the function in communication. Accordingly, in the present invention, a user can effectively use the communication terminal apparatus. Further, a user can select the function in communication, thereby realizing an operation environment of a communication terminal apparatus according to the user's individual preferences.
