## Background
PRIORITY
This application claims priority under 35 U.S.C. §119 to an application entitled “Apparatus and Method for Providing Incoming and Outgoing Call Information in a Mobile Communication Terminal” filed in the Korean Intellectual Property Office on Dec. 23, 2005 and assigned Serial No. 2005-128978, the contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to a mobile communication terminal, and more particularly to an apparatus and method for providing incoming and outgoing call information in a mobile communication terminal.
2. Description of the Related Art
With the development of communication technology, mobile communication terminals are widely being used. The Mobile communication terminals are communication devices for providing a phone call function while the user is on the move, for example, as mobile phones or personal information terminals.
Mobile communication terminals provide phone call functions and various additional functions. Specifically, mobile communication terminals provide a function for recording and storing incoming and outgoing call information and a function for displaying the incoming and outgoing call information in response to a user request.
For example, mobile communication terminals provide a function for displaying a recent call list of all incoming and outgoing call numbers including recently received call numbers, recently transmitted call numbers, recently missed call numbers and so on in reverse order of incoming and outgoing call occurrence times in response to the user request. Mobile communication terminals also provide a function for displaying a recent incoming call list of recently received call numbers in reverse order of incoming call occurrence times in response to the user request. In addition, mobile communication terminals provide a function for displaying a recent outgoing call list of recently transmitted call numbers in reverse order of outgoing call occurrence times in response to the user request. Mobile communication terminals provide a function for displaying a missed call list of recently missed call numbers in reverse order of missed call occurrence times in response to the user request.
Therefore, users can retrieve recent incoming and outgoing call information through the recent call list, recent incoming call list, recent outgoing call list, and missed call list.
The above-described conventional method for providing incoming and outgoing call information only provides an associated incoming/outgoing call list (e.g., the recent call list, recent incoming call list, recent outgoing call list, missed call list, and so on) on the basis of incoming/outgoing call occurrence times rather than phone numbers. Thus, it is difficult for an incoming/outgoing call history to be viewed at a glance on the basis of call numbers in the conventional method for providing incoming/outgoing call information.
When many incoming/outgoing calls relative to the same phone number occur, the associated phone number is repeatedly displayed many times only according to call occurrence times in the conventional incoming/outgoing call list. In the incoming/outgoing call list in which the number of phone numbers capable of being displayed is limited, other incoming/outgoing call numbers whose number corresponds to the number of repeated phone numbers cannot be displayed. The users may be inconvenienced to view other incoming/outgoing call numbers between repeatedly displayed phone numbers.
In the conventional incoming/outgoing call list, detailed incoming/outgoing call occurrence times relative to the same phone number are separately provided. When a user desires to view detailed incoming/outgoing call information relative to the same phone numbers, the user must select the same phone numbers of the list one by one. For example, when the same phone number is repeatedly displayed on the incoming/outgoing call list many times, the user is inconvenienced because the user must select all the same phone numbers from the first incoming/outgoing call number to the last incoming/outgoing call number one by one in order to view all incoming/outgoing call occurrence times relative to the same phone numbers.
Conventional mobile communication terminals can only store and delete a phone number of the incoming/outgoing call list, but do not provide a menu relative to a phone number of the incoming/outgoing call list. Accordingly, the degree of practical use of the incoming/outgoing call list is low.
SUMMARY OF THE INVENTION
It is, therefore, an object of the present invention to provide an apparatus and method for providing incoming and outgoing call information in a mobile communication terminal that enables the incoming and outgoing call information to be viewed on the basis of phone numbers.
It is another object of the present invention to provide an apparatus and method for providing incoming and outgoing call information in a mobile communication terminal that enables detailed incoming/outgoing call information mapped to the same phone number to be viewed at one time by integrating and providing the detailed incoming/outgoing call information mapped to the same phone number.
It is yet another object of the present invention to provide an apparatus and method for providing incoming and outgoing call information in a mobile communication terminal that can increase the degree of practical use of an incoming/outgoing call list and improve the convenience of a user by providing various menus relative to a phone number of the incoming/outgoing call list.
In accordance with an aspect of the present invention, there is provided an apparatus for providing incoming and outgoing call information in a mobile communication terminal, which includes a display unit for displaying detailed incoming/outgoing call information integrated for a particular phone number; a memory for storing an incoming/outgoing call list according to occurrence of an incoming/outgoing event; and a controller for controlling an operation for adding the detailed incoming/outgoing call information to an associated phone number item of the incoming/outgoing call list when the incoming/outgoing call event occurs and controlling an operation for displaying the detailed incoming/outgoing call information integrated for the particular phone number selected from among phone numbers of the incoming/outgoing call list.
In accordance with another aspect of the present invention, there is provided a method for providing incoming and outgoing call information in a mobile communication terminal, which includes adding detailed incoming/outgoing call information to an associated phone number item of an incoming/outgoing call list when an incoming/outgoing call event occurs; and displaying detailed incoming/outgoing call information integrated for a particular phone number selected from among phone numbers of the incoming/outgoing call list.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Preferred embodiments of the present invention will be described in detail herein below with reference to the accompanying drawings. In the drawings, the same or similar elements are denoted by the same reference numerals even though they are depicted in different drawings. In the following description, detailed descriptions of functions and configurations incorporated herein that are well known to those skilled in the art are omitted for clarity and conciseness.
FIG. 1 is a block diagram illustrating a structure of a mobile communication terminal in accordance with the present invention. The mobile communication terminal is provided with a controller 12, a Radio Frequency (RF) processor 14, an audio processor 16, a memory 18, a key input unit 20, and a display unit 22.
The controller 12 controls the overall operation of the mobile communication terminal. Specifically, the controller 12 controls an operation for adding detailed incoming/outgoing call information to an associated phone number item of an incoming/outgoing call list when an incoming/outgoing call event occurs and controls an operation for displaying an image of all detailed incoming/outgoing call information integrated for a particular phone number when the particular phone number of the incoming/outgoing call list is selected. Moreover, the controller 12 controls an operation for performing a phone number-related function, for example, an Address Book Register/Edit function or Reception Rejection Register/Release function, in response to a user request in a state in which the image of the detailed incoming/outgoing call information is displayed. The detailed incoming/outgoing call information can include date and time information mapped to an associated phone number as detailed incoming/outgoing call information of the associated phone number.
The RF processor 14 connected to the controller 12 performs a call transmission and reception function by transmitting an RF signal to and receiving an RF signal from a mobile communication base station through an antenna (ANT). That is, the RF processor 14 converts a received RF signal to an Intermediate Frequency (IF) signal, converts the IF signal to an analog baseband signal, converts the analog baseband signal to a digital signal, and applies the digital signal to the controller 12, thereby receiving an incoming call. Moreover, the RF processor 14 converts a digital baseband signal applied from the controller 12 to an analog IF signal, and converts the IF signal to an RF signal, thereby transmitting an outgoing call.
The audio processor 16 is connected to a microphone (MIC) and a speaker (SPK). The audio processor 16 generates data from a voice signal received from the microphone and then outputs the generated data to the controller 12. The audio processor 16 converts voice data input from the controller 12 to audible sound, outputs the audible sound through the speaker, and enables voice communication when an incoming/outgoing call occurs.
The memory 18 is constructed of a Read Only Memory (ROM) for storing information and multiple programs required at the time of controlling the operation of the mobile communication terminal in accordance with the present invention, a Random Access Memory (RAM), a voice memory, and so on. Moreover, the memory 18 is provided with an incoming/outgoing call history database in accordance with the present invention. The memory 18 stores an incoming/outgoing call list, for example, a recent call list, a recent incoming call list, a recent outgoing list, a missed call list, and so on, and stores detailed incoming/outgoing call information mapped to a particular phone number of the incoming/outgoing call list.
The key input unit 20 includes various keys including number keys, and provides key input data from the user to the controller 12. That is, the key input unit 20 outputs unique key input data to the controller 12 according to each input key. The controller 12 detects a key mapped to key input data and then performs an associated operation according to a detection result. The key input unit 20 applies associated key input data to the controller 12 when the user selects a particular phone number item of the incoming/outgoing call list. Moreover, the key input unit 20 applies, to the controller 12, key input data for displaying a phone number-related menu when the user presses a menu key in a state in which an image of the detailed incoming/outgoing call information is displayed.
Under control of the controller 12, the display unit 22 receives and displays key input data or displays an operating state of the mobile communication terminal and various information in the form of icons and characters. In accordance with the present invention, the display unit 22 displays an image of detailed incoming/outgoing call information integrated for a particular phone number item and displays a phone number-related menu in a state in which the image of the detailed incoming/outgoing call information is displayed, under the control of the controller 12.
The mobile communication terminal constructed as described above provides detailed incoming/outgoing call information integrated for a particular phone number, such that the user can view the detailed incoming/outgoing call information mapped to the same phone number at one time. Furthermore, in accordance with the present invention, the mobile communication terminal provides a phone number-related function in an image of detailed incoming/outgoing call information, thereby increasing the degree of practical use of an incoming/outgoing call list and improving convenience of the user.
A method for providing detailed incoming/outgoing call information in the mobile communication terminal in accordance with the present invention will be described in detail with reference to FIG. 2.
Referring to FIG. 2, the mobile communication terminal determines whether an incoming/outgoing call event has occurred in step 202. For example, the mobile communication terminal determines whether the incoming/outgoing call event has occurred by checking an incoming/outgoing call through the RF processor 14.
When the incoming/outgoing call event has occurred, the mobile communication terminal determines a type of the incoming/outgoing call event in step 204. At this time, the incoming/outgoing call event type may be an outgoing call, an incoming call, a missed call, or so on.
In step 206, the mobile communication terminal reads an incoming/outgoing call list from the incoming/outgoing call history database of the memory 18. For example, the mobile communication terminal reads a recent call list and a list mapped to the incoming/outgoing call event type from the incoming/outgoing call history database of the memory 18. When the incoming/outgoing call event type is an outgoing call, the mobile communication terminal reads a recent outgoing call list. When the incoming/outgoing call event type is an incoming call, the mobile communication terminal reads a recent incoming call list. When the incoming/outgoing call event type is a missed call, the mobile communication terminal reads a missed call list.
In step 208, the mobile communication terminal determines whether a phone number item relative to the incoming/outgoing call event is present in the incoming/outgoing call list. At this time, the phone number item can be displayed as a name mapped to an associated phone number. Each phone number item has detailed incoming/outgoing call information mapped to an associated phone number in a lower item.
If an associated phone number item is present in the incoming/outgoing call list, the mobile communication terminal proceeds to step 218 to add detailed incoming/outgoing call information mapped to the incoming/outgoing call event to the associated phone number item.
However, if an associated phone number item is absent in the incoming/outgoing call list, the mobile communication terminal generates a phone number item relative to the incoming/outgoing call event in step 210. The incoming/outgoing call list includes a limited number of phone number items. Thus, the mobile communication terminal determines whether the number of phone number items of the incoming/outgoing call list exceeds a limit number in step 212.
If the number of phone number items does not exceed the limit number, the mobile communication terminal updates the number of phone number items of the incoming/outgoing call list and adds the generated phone number item in step 214. However, if the number of phone number items exceeds the limit number, the mobile communication terminal deletes the lowest phone number item of the incoming/outgoing call list and adds the generated phone number item in step 216.
Then, the mobile communication terminal proceeds to step 218 to add detailed incoming/outgoing call information mapped to the incoming/outgoing call event to the phone number item. Herein, the detailed incoming/outgoing call information is incoming/outgoing call information mapped to an associated phone number to be provided in detail and can include date and time information about an incoming/outgoing call.
A process for adding detailed incoming/outgoing call information in step 218 will be described with reference to the flowchart of FIG. 3.
Referring to FIG. 3, the mobile communication terminal determines whether the number of detailed incoming/outgoing call information elements mapped to a phone number item exceeds a limit number in step 302.
If the number of detailed incoming/outgoing call information elements mapped to the associated phone number item does not exceed the limit number, the mobile communication terminal updates the number of detailed incoming/outgoing call information elements in step 304.
However, if the number of detailed incoming/outgoing call information elements mapped to the phone number item exceeds the limit number, the mobile communication terminal deletes the lowest detailed incoming/outgoing call information from prestored detailed incoming/outgoing call information in step 306. At this time, the lowest detailed incoming/outgoing call information is detailed incoming/outgoing call information stored for the longest time.
The mobile communication terminal then proceeds to step 308 to add detailed incoming/outgoing call information to an associated phone number item. The mobile communication terminal returns to the process of FIG. 2 after adding the detailed incoming/outgoing call information in steps 302 to 308 of FIG. 3.
Then, the mobile communication terminal proceeds to step 220 of FIG. 2 to store the added information in the incoming/outgoing call history database. The mobile communication terminal then displays an image of detailed incoming/outgoing call information mapped to a particular phone number item in response to a user request in step 222. That is, when the user selects the particular phone number item of an incoming/outgoing call list, the mobile communication terminal displays the image in which all detailed incoming/outgoing call information mapped to the selected phone number is integrated.
An incoming/outgoing call list and an image of detailed incoming/outgoing call information mapped to a phone number item thereof in accordance the present invention will be described in detail with reference to FIGS. 4 and 5.
FIG. 4 illustrates an example of an image of an incoming/outgoing call list in accordance with the present invention. FIG. 4(A) illustrates a recent call list. Referring to FIG. 4(A), the recent call list includes, for example, phone number items relative to all recently occurred incoming/outgoing events including a recent incoming call, a recent outgoing call, and a missed call. FIG. 4(B) illustrates a recent incoming call list. Referring to FIG. 4(B), the recent incoming call list includes recently received phone numbers. FIG. 4(C) illustrates a recent outgoing call list. Referring to FIG. 4(C), the recent outgoing call list includes recently transmitted phone numbers. FIG. 4(D) illustrates a missed call list. Referring to FIG. 4(D), the missed call list includes phone numbers of missed calls.
Referring to FIGS. 4(A) to 4(D), icons for indicating incoming/outgoing call event types are displayed in phone number items. The icons for indicating the incoming/outgoing call event types may be an icon 42 for indicating a recently received phone number, an icon 44 for indicating a recently transmitted phone number, and an icon 46 for indicating a phone number of a missed call. A phone number item can be displayed in the form of a name mapped to an associated phone number when the name is prestored. When the prestored name is not present, the associated phone number can be displayed. Each phone number item has detailed incoming/outgoing call information mapped to an associated phone number as a lower item. As indicated by reference numeral 48, the number of detailed incoming/outgoing call information elements present in the lower item is displayed along with the phone number item.
When the user selects a particular phone number from the phone number items displayed as described above, the mobile communication terminal displays an image of detailed incoming/outgoing call information mapped to the lower item of the selected phone number item.
FIG. 5 illustrates an example of an image of detailed incoming/outgoing call information in accordance of the present invention. FIG. 5(A) illustrates a recent call list. The user can select each phone number item from the recent call list as illustrated in FIG. 5(A). FIG. 5(A) corresponds to the case where “Office” is selected. When a phone number item such as “Office” is selected, the mobile communication terminal displays an image 50 of detailed incoming/outgoing call information as illustrated in FIG. 5(B). The image 50 is displayed in which all date and time information of incoming/outgoing calls is integrated for the selected phone number item.
This image of detailed incoming/outgoing call information enables the user to view all detailed incoming/outgoing call information mapped to a particular phone number item of the incoming/outgoing call list at a glance.
In accordance with the present invention, the mobile communication terminal provides a phone number-related menu in a state in which an image of incoming/outgoing call information is displayed and performs a function based on menu selection by the user.
FIG. 6 is a flowchart illustrating a process for performing a phone number-related function in an image for displaying detailed incoming/outgoing call information in accordance with the present invention. Referring to FIG. 6, the mobile communication terminal displays an image of detailed incoming/outgoing call information mapped to a phone number item selected by the user in step 602.
The mobile communication terminal determines whether the user makes a request for displaying a phone number-related menu in step 604. At this time, the mobile communication terminal can determine that the request for displaying the phone number-related menu is present when, for example, a menu key is input through the key input unit 22.
When the request for displaying the phone number-related menu is present, the mobile communication terminal displays the phone number-related menu on the image of detailed incoming/outgoing call information in step 606. The phone number-related menu may be an address book menu, a reception rejection menu, and so on.
A method for displaying the address book menu will be described with reference to the example FIG. 7.
FIG. 7(A) displays a phone number-related menu 70 in a state in which an image 50 of detailed incoming/outgoing call information mapped to “Office” of a recent outgoing call list is displayed. When a previously registered name (e.g., “Office”) mapped to a phone number is present in the currently displayed image of detailed incoming/outgoing call information as illustrated in FIG. 7(A), the mobile communication terminal determines that an associated address book is present, and displays an “Address Book Edit” option 72 in the address book menu mapped to the phone number-related menu 70.
FIG. 7(B) displays a phone number-related menu 70 in a state in which an image 50 of incoming/outgoing call information for “Unregistered Number” of the recent outgoing call list is displayed. When a previously registered name mapped to the phone number is absent in the currently displayed image of detailed incoming/outgoing call information as illustrated in FIG. 7(B), the mobile communication terminal determines that an associated address book is absent, and displays an “Address Book Register” option 74 in the address book menu of the phone number-related menu 70.
A method for displaying the reception rejection menu will be described with reference to the example of FIG. 8.
FIG. 8(A) displays a phone number-related menu 70 in a state in which an image 50 of detailed incoming/outgoing call information mapped to “Office” of a missed call list is displayed. When reception rejection for a phone number is not registered in the currently displayed image of detailed incoming/outgoing call information, the mobile communication terminal displays a “Reception Rejection Register” option 82 in the reception rejection menu of the phone number-related menu 70 as illustrated in FIG. 8(A).
FIG. 8(B) displays a phone number-related menu 70 in a state in which an image 50 of incoming/outgoing call information for “Unregistered Number” of the missed call list is displayed. When reception rejection for the phone number is registered in the currently displayed image of detailed incoming/outgoing call information, the mobile communication terminal displays a “Reception Rejection Release” option 84 in the reception rejection menu of the phone number-related menu 70 as illustrated in FIG. 8(B).
Referring back to FIG. 6, after the phone number-related menu is displayed in the image of detailed incoming/outgoing call information, the mobile communication terminal determines whether the user's menu selection is present in step 608. For example, the mobile communication terminal determines whether an Address Book Register or Edit option is selected or a Reception Rejection Register or Release option is selected.
When the Address Book Register or Edit option is selected, the mobile communication terminal displays an Address Book Register or Edit image in step 610. In step 612, an Address Book Register or Edit operation for an associated phone number is performed.
When the Reception Rejection Register or Release option is selected, the mobile communication terminal displays a Reception Rejection Register or Release image in step 614. In step 616, a Reception Rejection Register or Release operation for an associated phone number is performed.
When the reception rejection is registered through an image of a phone number-related menu in the image of detailed incoming/outgoing call information, the mobile communication terminal performs a reception rejection function.
FIG. 9 is a flowchart illustrating a process for performing a reception rejection function in accordance with the present invention. Referring to FIG. 9, the mobile communication terminal determines whether an incoming/outgoing call event occurs in step 902. When the incoming/outgoing call event occurs, the mobile communication terminal determines whether a phone number relative to the occurred incoming/outgoing call event is registered for reception rejection in step 904.
If the phone number is not registered for reception rejection, the mobile communication terminal gives notification of an incoming call through a ring tone or vibration in step 906. Then, the mobile communication terminal determines whether the user receives the incoming call in step 908. If the user receives the incoming call, the mobile communication terminal registers the phone number in the recent call list and the recent incoming call list in step 910.
However, if the phone number is registered for reception rejection, the mobile communication terminal transmits, to a transmitting side, a message for indicating that a phone call cannot be received in step 912. Then, the mobile communication terminal registers the associated phone number in the recent call list and the missed call list in step 914.
As described above, the present invention enables the detailed incoming and outgoing call information mapped to the same phone number to be viewed at one time by integrating and providing detailed incoming/outgoing call information mapped to a particular phone number.
The present invention can increase the degree of practical use of an incoming/outgoing call list by providing a phone number-related function in an image of detailed incoming/outgoing call information. Moreover, the present invention improves the convenience of a user by performing an Address Book Register or Edit function and a Reception Rejection Register or Release function in an image of detailed incoming/outgoing call information.
