`
`MOBILE COMMUNICATION TERMINAL
`PROVIDED WITH HANDSFREE FUNCTION AND
`CONTROLLING METHOD THEREOF
`
`BACKGROUND OF THE INVENTION
`
`(0001]
`
`1. Field of the Invention
`
`[0002] The present invention relates to a mobile commu-
`nication terminal, and moreparticularly, to a mobile com-
`munication terminal provided with a hands-free function
`capable of originating a call or receiving a call by a user’s
`voice command and a controlling method thereof.
`
`[0003]
`
`2. Description of the Related Art
`
`[0004] Generally, a mobile communication terminal such
`as a cellular phone and a PCS phone is a communication
`device for transmitting and receiving a radio signal differ-
`ently from a wire telephone. Recently, as the mobile com-
`munication terminal becomes small and light so as to be
`convenientfor carrying, a user can originate a call or receive
`a call at any time.
`
`[0005] However, recently, it is regulated to directly use the
`mobile communication terminalat the time of driving since
`it may cause an unexpected accident due to an attention
`lowering. That is, when the user receives a call at the time
`of driving, the user has to press a button of the mobile
`communication terminal or open a folder by using hands,
`and whenthe useroriginatesa call, eyes of the user have to
`be towards the mobile communication terminal with hands
`thus to lower the user’s attention.
`
`[0006] By reflecting the direct use regulation for the
`mobile communication terminal, a hands-free function for
`calling in a predetermined space without directly holding the
`mobile communication terminal by hands or for charging a
`battery was developed.
`
`[0007] A mounting unit of the hands-free is constructed to
`mount a microphone and a speakerphone to the mobile
`communication terminal, the microphone is mounted at a
`position near to the user, and the speakerphone is mounted
`at a position where the user can easily hear.
`
`in case of additionally mounting the
`[0008] However,
`conventional hands-free, the microphone and the speaker-
`phone have to be mounted and the hands-free has to be
`mounted by wire after changing an indoor structure, a
`garnish, and etc. in order to connect a battery power used in
`a vehicle and etc.
`
`[0009] Also, in case of additionally mounting the conven-
`tional hands-free, the user has a cost burdenfor installing the
`hands-free.
`
`SUMMARYOF THE INVENTION
`
`[0010] Therefore, an object of the present invention is to
`provide a mobile communication terminal provided with a
`hands-free function capable of calling withouta user’s hands
`using at the time of originating a call or receiving a call
`while driving and a controlling method thereof.
`
`To achieve these and other advantages and in
`[0011]
`accordance with the purpose of the present invention, as
`embodied and broadly described herein, there is provided a
`mobile communication terminal provided with a hands-free
`function comprising: a key inputting meansfor inputting an
`
`operational commandof a mobile communication terminal;
`a microphonefor inputting a user’s voice message; a display
`unit for displaying an operational state of the mobile com-
`munication terminal; a speakerphonefor outputting a calling
`party’s voice outside in a hands-free mode; and a control
`means for setting a calling mode according to the user’s
`voice message, searching the calling party’s nameortele-
`phone numberaccording to the user’s voice message and
`thereby voice-guiding through the
`speakerphone,
`and
`switching a calling path through the speakerphone to an
`earphone at the time of setting a secret calling.
`
`(0012] A controlling method of a mobile communication
`terminal provided with a hands-free function comprises the
`steps of: setting a hands-free function of a mobile commu-
`nication terminal; certifying whether an originating calling
`command or a calling from outside are received; searching
`information of a calling party inputted by a user’s voice or
`originating party’s information from a mounted telephone
`directory; and voice guiding the calling party’s information
`and connecting a calling.

`with the calling party. At this time, the user hears the calling
`party’s voice through the speaker 150 and inputs voice
`through the microphone 140.
`
`[0027] Reference will now be made in detail to the pre-
`ferred embodiments of the present invention, examples of
`which are illustrated in the accompanying drawings.
`
`[0028] Hereinafter, a mobile communication terminal pro-
`vided with a hands-free function and a controlling method
`thereof according to the present invention will be explained.

`tion.
`
`[0037] The user sets a hands-free function at a menu
`screen by using the key inputting unit 110 before driving or
`by pressing an arbitrary key suchasa preset side key (S301).
`At this time, the micro computer 120 powers-on the speak-
`erphone 160, a NUM key,a voice recognition/voice guiding
`function, and a voice commandfunction, then sets volume
`of the speakerphone 160 and volumeof a ring tone as a
`properlevel in the vehicle, and greatly modifies a letter font
`size of the display unit.
`
`the mobile communication terminal

`microphone 140 in controlling an operation for a calling.
`hands-free function. When the secret calling functionis set,
`a calling path set as the speakerphone 160 is switched into
`a calling path using an earphone (S304).
`
`[0031] The micro computer 120 is provided with a wire-
`less communication module, a video processing module, a
`display driving module, an audio processing module, and a
`calling path switching module for switching a calling path
`between the speaker 150 and the speakerphone 160 or
`switching a calling path between the speakerphone 160 and
`an earphone (not shown).
`
`[0032] The micro computer 120 comprises a voice-guid-
`ing function for obtaining a calling parly’s information CID,
`thereby searching whether the information is registered in a
`telephone directory mounted in the mobile communication
`terminal, and guiding the search result by voice when a
`calling from an arbitrary originating party is received; a
`voice-dialing function for recognizing calling party’s infor-
`mation inputted by the user’s voice, thereby searching from

`
`[0039] The secret calling function can be set or released
`not only through a specific key inputting but also the user’s
`voice command. Also, the hands-free function and the secret
`calling function can be set not only sequentially but also can
`be set independently, respectively.

`
`[0041] First, when the hands-free function has been set to
`the mobile communication terminal (S401), the micro com-
`puter 120 checks whether voice relevant to a callingtrial has
`been inputted through an output signal of the microphone
`140 (S402).
`
`[0042] Whenthe voice relevant to a calling trial has been
`inputted to the microphone 140, the micro computer 120
`outputs a voice guiding through the speakerphone 160. That
`is, if the user inputs voice of a calling connection, a calling
`trial, a calling, and etc., the micro computer 120 outputs a
`voice guiding such as ‘please leave your namealler the
`beep’.
`
`[0043] Whenthe user of the mobile communication ter-
`minal inputs a calling party’s name through the microphone
`140 (S403), the micro computer 140 searches a mounted
`telephone directory (S404) thus to certify whether the call-
`ing party’s name inputted by the user’s voice exists (S405).
`At this time, the micro computer 140 displays the calling
`party’s name inputted by the user’s voice at the display unit
`130 and thereby the user can certify the calling party’s name
`has been precisely recognized.
`
`[0044] Whenthe calling party’s name has been certified
`from the telephone directory, the micro computer 120 out-
`puts a corresponding name to the speakerphone 160 thus to
`guide to the user by voice (S406) and the user checks
`whether the certified name is consistent with the calling
`party (S407).
`
`Ifthe searched calling partyis not the calling party
`[0045]
`inputted by the user, the user inputs voice such as ‘Heis not
`a corresponding calling party.’ to the microphone 140 and
`the micro computer 120 returns the mobile communication
`terminal to the process for inputting a calling party’s name
`(S403).
`
`If the searched calling party is a desired calling
`[0046]
`party, the user inputs a voice message for admitting the
`search result such as ‘OK’, ‘Heis a calling party.’, ‘He is a
`right calling party.’, and etc. to the microphone 140.
`
`Incasethat the searchedcalling party’s registration
`[0047]
`telephone numberis one, the micro computer 120 originates
`a calling with a corresponding telephone numberthus to
`perform a calling connection (S410). However, in case that
`registered telephone numbers are more than two, the micro
`computer 120 sequentially guides the telephone numbers by
`voice through the speakerphone 160 (S409), and when the
`user selects a desired telephone number, the micro computer
`120 originates a calling with the selected telephone number
`thus to perform a calling connection (S410).
`
`[0048] A case that the searched telephone numbers are
`plural will be explained in more detail with reference to
`FIG.6.
`
`If telephone numbers registered for the calling
`[0049]
`party are plural (S601), the micro computer 120 outputs a
`voice message such as
`‘Plural
`telephone numbers are
`searched.’ to the speakerphone 160, and outputs a voice
`message such as ‘Where do you want to call among home,
`office, or cellular phone?’ to the speakerphone 160 (S602).
`
`[0050] Whenthe userselects one to which a calling will be
`connected and inputs by voice to the microphone 140, the
`micro computer 120 guides a corresponding telephone num-
`ber by voice (S603) and then tries a calling connection
`(S604). Herein, even if the plural telephone numbers were
`aforementioned by being divided into home, oftlice, and
`cellular phone, more telephone numbers can beregistered if
`necessary.
`
`[0051] Whenthe calling party has not been searched from
`the mounted telephone directory, the micro computer 120
`outputs a voice message such as ‘No correspondingcalling
`party’s name’ to the speakerphone 160 (S411), and outputs
`a voice message such as ‘Would you inputthe calling party’s
`telephone number by voice?’ to the speakerphone 160
`(S412).
`
`[0052] Then, the user inputs a certification message such
`as “Yes’ or
`‘OK’ that he will
`input
`the calling party’s
`telephone numberby voice to the microphone 140 and then
`inputs the calling party’s telephone numberby voice (S413),
`the micro computer 120 originates a calling to the telephone
`number thus to perform a calling connection (S410).
`
`[0053] However, when the user inputs a voice message for
`finishing a calling trial such as ‘Calling finish’, ‘Calling
`refusal’, or ‘NO’ to the microphone 140 for a voice message
`such as ‘Would you input
`the calling party’s telephone
`numberby voice?’ or presses an arbitrary key such as a side
`key or a finishing key (S414),
`the micro computer 140
`outputs a voice message such as ‘A calling trial has been
`finished.’ to the speakerphone 160 and then finishes the
`calling trial process (S415). At this time, the user does not
`input a calling finish command within a certain time, the
`micro computer 120 returns to a calling waiting state for
`recciving the calling party’s name.
`
`[0054] A case that several same calling party’s names are
`searched during the process (S404) for searching the calling
`party’s name inputted by the user will be explained in more
`detail with reference to FIG.5.
`
`[0055] When the same calling party’s names more than
`two as the calling party inputted by the user’s voice are
`searched (S501, S502), the micro computer 120 outputs a
`voice message such as ‘The sameplural calling parties have
`been searched.’ to the speakerphone 160 (S503), and guides
`telephone numbersof the searched respective calling parties
`to the user by voice (S504).
`
`If the user certifies whether the guided telephone
`[0056]
`numberis the calling party’s telephone number (S505) and
`then inputs a voice message such as ‘NO’, ‘Calling refusal’,
`and ‘He is not a corresponding calling party.’ to the micro-
`phone 140, the micro computer 120 guides a next calling
`party’s telephone number by voice (S504), and if the user
`inputs a voice message for allowing the search result such as
`‘OR’, or ‘Heis the calling party.’ to the microphone 149,the
`micro computer 120 originates a calling to the correspond-
`ing telephone number thus to perform a calling connection
`(S506).

`
`In case that plural calling parties having the same
`[0057]
`nameas the calling party are searched, the searched calling
`parties’
`telephone numbers were sequentially guided by
`voice in the above process. However, identification names
`such as home, a company address, and a company name for
`identifying each calling party can be inputted by the user’s
`voice just at the time of searching the plural calling parties,
`therebycertifying the calling party right now and perform-

`microphone 120 outputs the calling party’s voice to the
`speakerphone 160 and transmits the user’s voice inputted to
`the microphone 140 to the calling party by a wireless
`communication, thereby performing a calling between the
`user and the calling party (S709).
`
`[0066] Whenthe calling between the user and the calling
`parly has been finished (S709),

`If the user inputs a voice message such as ‘NO’,
`[0059] As shownin FIG.9, whenacalling finishing signal
`“Calling refusal’, or ‘Calling finish’ to the microphone 140
`is received from the calling party (S901) or when the user

`[0060] FIGS. 7 and 8 are flow charts showing a process
`arbitrary key such as a side key orafinishing key instead of
`for receiving a calling in a state that the hands-free function

`that the calling has been refused by flickering a mute lamp
`FIG.7 is a flow chart showing a processfor receiving a call
`or by using a voice message.
`according to an embodiment of the present invention and
`FIG.8 is a flow chart showing call allowing and refusing
`processes of FIG.7.
`
`[0068] The process for a calling allowance or a calling
`finish $707 of FIG. 7 will be explained with reference to
`FIG.8.
`
`[0061] When the hands-free function of the mobile com-
`munication terminal has been set (S701), the micro com-
`puter 120 checks whether a calling request message is
`received from an arbitrary originating party (S702).
`
`[0062] When the calling request message has been
`received,
`the micro computer 120 temporarily stores an
`originating party’s call
`identifier (CID) and a telephone
`number and searches a mounted telephone directory (S703)
`thus to certify whether a telephone number consistent with
`the telephone numberexists (S704). At this time, it can be
`constructed for the micro computer 120 to guide the calling
`request message reception to the user by voice and then
`search the telephone directory.
`
`Ifthe calling party’s telephone numberexists in the
`[0063]
`mounted telephone directory (S704), the micro computer
`guides a calling party’s name correspondingto the telephone
`number by voice by using a text to speech function (S705).
`At this time, it can be constructed for the micro computer
`120 to display searched namesatthe display unit 130 so that
`the user can precisely recognize the originating party’s
`name.
`
`In case that the micro computer has not searched
`[0064]
`the originating party’s telephone number from the mounted
`telephone numberdirectory, a received telephone numberis
`voice-guided through the speakerphone 160 (S706).
`
`(0065] After guiding the originaling party’s nameortele-
`phone number by voice, the micro computer 120 outputs a
`voice message such as ‘Would you call?’ to the speaker 160
`and certifies the user’s voice received through the micro-
`phone 140 thus to determine a calling allowance with the
`originating party or not. (S707). That is, when the user inputs
`voice for a calling allowance such as ‘OK’, ‘Calling allow-
`
`[0069] When an originating party’s name or a telephone
`numberofan originating calling are guided by voice (S705,
`$706),
`if the user inputs a voice message for a calling
`allowance to the microphone 140 (S801) or inputs a preset
`arbitrary key such as a calling key (S802),
`the micro
`computer 120 judges as a calling allowance (S803). How-
`ever, if the user inputs a voice message relevantto a calling
`finish to the microphone 140 (S804) or inputs a preset
`arbitrary key such as a finishing key (S805),
`the micro
`computer 120 judges as a calling refusal (S806).
`
`[0070] A calling connection process in a secret calling
`according to the present invention will be explained as
`follows. Herein,the secret calling is performed by processes
`shown in FIGS. 4 to 7 for convenience while driving, and
`whenthere is a car occupant next the user, the user can hear
`the calling party’s voice only by an earphone.
`
`Firstof all, at the time of calling with an arbitrary
`{0071]
`originating party in the secret calling setting state, the user
`inputs a telephone number by using a key pad provided at
`the key inputting unit 110, then presses a calling key thus to
`connecta calling, and inputs voice to a microphone provided
`al an earphone while hearing the calling party’s voice bythe
`earphone undera state that calling has been connected.
`
`[0072] When the secret calling is not necessary even if
`there is a car occupant, as shown in FIG.3, the user inputs
`a calling party’s nameor telephone name to the microphone
`140 by voice and the micro computer 120 searches a
`mounted telephone directory thus to guide the search result
`by voice. Whenthe user inputs a calling allowance for the
`searched result to the microphone 140 by voice, the micro
`computer 120 connects a calling with the calling party by a
`wireless communication. At this time, the user can switch a

`mand of a mobile communication terminal;
`
`[0073] Also, when a calling from an arbitrary originating
`party is generated under a state that the secret calling has
`been set, as shown in FIG. 7,
`the micro computer 120
`temporarily stores the calling party’s call identifier (CID)
`and telephone number, then informs the user that there is a
`calling reception through the speakerphone 160, and
`searches a mounted telephone directory thus to certify
`whether the corresponding telephone numberexists. Then,
`the micro computer 120 guides the calling party’s name or
`telephone numberto the user through an earphone. Whenthe
`user inputs voice for a calling allowance to a mike provided
`at the earphoneor presses an arbitrary key such as a calling
`key or aside key, the micro computer 120 judgesas a calling
`allowancestate thus to output the calling party’s voice to the
`user through the earphone and transmits the user’s voice
`inputted to the microphoneto the calling party.

`user’s voice message, searching the calling party’s
`name or telephone number according to the user’s
`voice message and thereby voice-guiding through the
`speakerphone, and switching a calling path through the
`speakerphone to an earphone at the time of setting a
`secret calling.

`
`If it doesn’t matter for a car occupant to hear
`[0074]
`calling contents or the car occupant need not a calling when
`a calling from an arbitrary originating partyis generated, the
`user releases the set secret calling by pressing an arbitrary
`key. Then, the micro computer 12 switches a calling path
`from the earphone to the speakerphone 160 and inputs the
`a voice-dialing function for searching calling party’s
`user’s voice to the microphone 140. That is, even if the
`ioformation inputted by a user’s voice from the
`secret calling has been set, if the user releases the secret
`mounted telephone directory and outputting the search
`calling setting by pressing an arbitrary key such asaside
`result by voice; and

`voice to the speakerphone 160 and recognizes voice through
`the microphone 140 or a mike provided at the earphone,
`thereby enabling for not only the user but also the car
`occupant to call with the calling party.
