Abstract

The present invention relates to a call control method and a mobile communication terminal performing the same.

According to the present invention, the mobile communication terminal equipped with the voice recording function determines whether the other party's telephone number to be connected to the call is an unregistered number in the address book before the call is connected. As a result of the determination, the unregistered number is automatically recorded while the call is connected. The recorded call contents are stored in association with the call history of the unregistered counterpart's telephone number. Thereafter, before connecting an outgoing call or an incoming call with an unregistered counterpart, the recorded call content is reproduced according to a user's selection so that the call is connected after user confirmation.

As such, by automatically recording a part of the contents of the call with the counterpart who is not registered in the address book and storing the call contents together with the call history, it can be usefully used as information for the user to identify the call counterpart.

Description

Call control method and mobile communication terminal performing the same

The present invention relates to a call control method and a mobile communication terminal performing the same. More particularly, the present invention relates to a method of controlling a call when calling or receiving a counterpart phone number not stored in an address book and a mobile communication terminal performing the same.

In general, a mobile communication terminal has an address book that stores information of a frequently used counterpart. The address book stores data such as name, phone number, group, email address, and memo. When making a call, the user can easily make a call using the address book without having to dial the other party's phone number.

In general, a mobile communication terminal provides a call history of a user. The call history is provided through a recent call list menu, and provides information such as a phone number, a caller's name, a date, a call time including the day of the week, and a call time. The user can easily re-call by selecting a desired target from the recent call list without selecting a menu.

At this time, when the calling number and the called number of the recent call list are the phone numbers stored in the address book, the name registered in the address book is displayed on the call history in conjunction with the address book. Therefore, the user can easily grasp information on the counterpart to whom he has recently called and can conveniently use it when re-calling.

However, when a call is made to a number not registered in the address book, even if the call history is recorded in the recent call list, information for identifying the other party is not displayed, so that the user cannot identify the other party's identity. In addition, this is especially true for temporary parties who do not store and manage contacts.

However, in the related art, in order to re-call with a counterpart not stored in the address book, there is an inconvenience of having to make a call by finding a counterpart phone number by estimating a past call time zone on a recent call list. Alternatively, there is a problem that a cumulative operation of temporarily storing the address book for re-calling and then deleting it when there is no need for it is accompanied.

In addition, these days, since the caller ID service is generally used, when a call is received, the caller's number is not only displayed on the incoming screen but also the other party's name is displayed in the address book. However, if not registered in the address book, only the caller ID is displayed. Therefore, when a call is received from a counterpart who has not been stored in the address book but has made a call in the past, there is a problem that the call is received without grasping the counterpart even though the call was received in the past.

On the other hand, although a mobile communication terminal equipped with a voice recording function is prevalent, it is inconvenient to press the record button every time a user needs to store the contents of a call. That is, it is inconvenient to manually record the contents of the call by selecting the record button before the call or during the call.

Accordingly, a technical problem to be achieved by the present invention is to automatically record the contents of a call with an unregistered counterpart in the address book, and then provide the call outgoing or incoming call to use it as information for identifying the counterpart and performing the same. It is to provide a mobile communication terminal.

Call control method according to a feature of the present invention in order to achieve the above problems,

A call control method of a mobile communication terminal having a voice recording function, the method comprising: (a) determining whether a counterpart telephone number to be called is an unregistered number in an address book before a call is connected; (b) in the case of an unregistered number, automatically recording a call while performing a call connection; And (c) storing the contents of the call recorded in the step (b) in association with the call history of the unregistered counterpart's telephone number.

In addition, the mobile communication terminal according to another aspect of the present invention,

In a mobile communication terminal equipped with a voice recording function, before the call is connected, if the other party's telephone number to be called is an unregistered number in the address book, the voice recording function is executed while the call is connected to automatically record and record the contents of the call. A control unit for storing the connected call contents in association with the call history of the unregistered counterpart phone number; And a storage unit for storing a call history of the recorded call contents and the unregistered counterpart phone number associated with the recorded call contents.

According to the present invention, by automatically recording a part of the contents of the call with the counterpart who is not registered in the address book and storing it together with the call history, it can be usefully used as information for the user to identify the call counterpart.

In addition, when a call is received from an unregistered counterpart in the address book, the user may check the counterpart and then make a call by providing a user selection item capable of receiving the call after playing the recorded past call contents.

Now, a call control method and a mobile communication terminal performing the same according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the internal configuration of a mobile communication terminal according to an embodiment of the present invention.

As shown in FIG. 1, the mobile communication terminal 100 includes a storage unit 110, a control unit 120, a wireless communication unit 130, a key input unit 140, and a display unit 150.

The storage unit 110 basically stores a program required for the operation of the mobile communication terminal 100 and various data generated by the operation of the mobile communication terminal 100.

The storage unit 110 includes an address book DB 112, a registered call log DB 114, and an unregistered call log DB 116 in detail.

The address book DB 112 stores an address book aka phonebook composed of a plurality of counterpart information registered by the user. The address book stores information such as the other party's name, mobile phone number, home phone number, company phone number, fax number, email address, address, and short note.

The registered call history DB 114 and the unregistered call history DB 116 are conventionally composed of one call history DB. That is, it stores information on the call history that the user recently called or received, and stores the call time including the other party's phone number, the other party's name, the date, the day of the week, and the call time.

Here, the registered call history DB 114 interlocks with the address book DB 112 and stores the call history with the counterpart registered in the address book DB 112.

The unregistered call log DB 116 stores a call log with an unregistered counterpart in the address book DB 112. In this case, the recorded call contents are stored when a call is made with the unregistered counterpart associated with the call history of the unregistered counterpart phone number.

The controller 120 controls the overall operation of the mobile communication terminal 100 including call and data communication processing.

The controller 120 determines whether the other party's telephone number to be called before the call connection is an unregistered number in the address book, and if it is an unregistered number, the voice recording function is automatically executed to record the call while the call is connected.

In this case, the controller 120 records a part of the call content, that is, the call content for a specific time, instead of the entire call content. Here, the specific time is a predefined time that is expected to obtain a call content that can identify the other party. According to an embodiment, the contents of the call for 10 seconds from the time of the first call are recorded.

The controller 120 stores the recorded call contents in the unregistered call history DB 116 in association with the call history of the unregistered counterpart's telephone number. In this case, in order to play the recorded call content, a password input by the user may be set to perform password authentication.

When the controller 120 outputs the call history stored in the unregistered call history DB 116 to the recent call list, the controller 120 provides a selection item for reproducing the recorded call contents through the recent call list menu screen.

When the call connection request signal is received from the other party stored in the unregistered call history DB 116, the control unit 120 outputs a selection item for playing the recorded call contents together with the calling number on the incoming screen before the call connection. Allows you to check the recorded call.

When the password is set in the unregistered call log DB 116, the controller 120 requests a password input when playing the recorded call contents is selected from the user, and records the recorded call when the password entered by the user matches the set password. Play the content.

When the storage capacity of the recorded call contents exceeds the predefined threshold storage capacity in consideration of the storage capacity of the unregistered call history DB 116, the controller 120 stores a time point of the recorded call contents stored in time series. Delete the oldest recorded call sequentially.

In addition, the controller 120 outputs the call history stored in the registered call history DB 114 to the recent call list so that the counterpart name registered in the address book DB 112 is displayed. When the call connection request signal from the counterpart stored in the registered call log DB 114 is received, the counterpart name registered in the address book DB 112 is displayed on the incoming screen. At this time, a selection item for reproducing the recorded call content is not output.

The wireless communication unit 130 receives the call connection request signal from the mobile communication network through the antenna and transmits the call connection request signal to the controller 120 or moves the call connection request signal to the counterpart phone number displayed in the recent call list output by the controller 120. Output to the network.

The key input unit 140 includes a plurality of numeric keys and various function keys for inputting a counterpart phone number and a playback selection key of the recorded call contents. The key input unit 140 generates a key signal according to a user's key input and transmits the key signal to the controller 120.

The display unit 150 is a means for displaying an operation state of the mobile communication terminal 100 under the control of the controller 120. The display unit 150 outputs one or more of a call history screen including a selection item for reproducing the recorded call contents, an incoming call screen, and a password input screen for reproducing the recorded call history.

2 and 3 show examples of screens that the controller 120 outputs through the display unit 150.

First, FIG. 2 shows a recent call list screen according to an embodiment of the present invention.

As shown in FIG. 2A, the recent call list includes a call history (02-886-XXXX) stored in an unregistered call history DB 116 and a call history stored in the registered call history DB 114 (Kim, Young Hee, Lee Cheol Soo, Park Moo Hyuk). ) Is displayed.

At this time, the call history (02-886-XXXX) stored in the unregistered call history DB 116 displays information indicating the incoming call (incoming call), the incoming date and time (2008/09/04 [Thu] 05:07 PM) do. Unlike the conventional 'listening' item has been added. The 'Listen' item is an option for playing the recorded call.

When the user clicks the 'listen' item, the screen switches to the screen of FIG. 2B and the recorded call contents are played. When the user clicks the 'end' item again, the screen of FIG. 2A is switched to and the corresponding party can be called by pressing the call button with the call history (02-886-XXXX) activated.

Therefore, when a call is made with the other party who has previously made a call without being registered in the address book, the call may be confirmed after confirming the other party by confirming the recording contents previously called.

3 shows an incoming call screen according to an embodiment of the present invention.

As shown in Fig. 3A, an incoming call number (02-886-XXXX) is displayed on the incoming call screen indicating that a call has arrived. In this case, when the other party is registered in the address book, information for identifying the other party, that is, the name of the other party is displayed, but the calling party number is displayed when the other party is not registered in the address book.

Here, since the other party is the other party in which the call history is stored in the unregistered call log DB 116, not only the calling number is displayed but also the 'listening' item is displayed. The 'Listen' item is an option for playing the recorded call.

When the user clicks the 'listen' item, the screen is switched to FIG. 3B and the recorded call contents are played. When the user clicks the 'end' item again, the screen of FIG. 2A is switched, and when the user clicks the 'call' button, a call is made with the other party.

Therefore, the user can call after confirming the user by playing the recorded call content before the call connection.
