invention, FIG. 8 is a flow chart showing call allowing and
refusing processes of FIG. 7, and FIG. 9 is a flow chart showing a
call finishing process according to an embodiment of the present
invention.
First, when the hands-free function has been set to the mobile
communication terminal (S401), the micro computer 120 checks
whether voice relevant to a calling trial has been inputted through
an output signal of the microphone 140 (S402).
When the 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 name after the beep`.
When the user of the mobile communication terminal 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 calling 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.
When the calling party's name has been certified from the telephone
directory, the micro computer 120 outputs 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).
If the searched calling party is not the calling party inputted by
the user, the user inputs voice such as `He is 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 party, the user
inputs a voice message for admitting the search result such as
`OK`, `He is a calling party.`, `He is a right calling party.`, and
etc. to the microphone 140.
In case that the searched calling party's registration telephone
number is one, the micro computer 120 originates a calling with a
corresponding telephone number thus 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).
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 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).
When the user selects one to which a calling will be connected and
inputs by voice to the microphone 140, the micro computer 120
guides a corresponding telephone number by voice (S603) and then
tries a calling connection (S604). Herein, even if the plural
telephone numbers were aforementioned by being divided into home,
office, and cellular phone, more telephone numbers can be
registered if necessary.
When the calling party has not been searched from the mounted
telephone directory, the micro computer 120 outputs a voice message
such as `No corresponding calling party's name` to the speakerphone
160 (S411), and outputs a voice message such as `Would you input
the calling party's telephone number by voice?` to the speakerphone
160 (S412).
Then, the user inputs a certification message such as `Yes` or `OK`
that he will input the calling party's telephone number by voice to
the microphone 140 and then inputs the calling party's telephone
number by voice (S413), the micro computer 120 originates a calling
to the telephone number thus to perform a calling connection
(S410).
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 number by 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 receiving the calling
party's name.
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.
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 same plural
calling parties have been searched.` to the speakerphone 160
(S503), and guides telephone numbers of the searched respective
calling parties to the user by voice (S504).
If the user certifies whether the guided telephone number is 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 microphone 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 `OK`, or `He is the calling party.` to
the microphone 140, the micro computer 120 originates a calling to
the corresponding telephone number thus to perform a calling
connection (S506).
In case that plural calling parties having the same name as 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, thereby certifying the calling party right now and
performing a calling connection to the telephone number.
When a calling is connected by said process, the user hears the
calling party's voice through the speakerphone 160, then inputs a
calling voice to the microphone 140 thus to perform a calling with
his desired calling party, and finishes a calling.
As shown in FIG. 9, when a calling finishing signal is received
from the calling party (S901) or when the user presses a side key
or a finishing key preset to recognize a calling finishing if the
user presses during a calling (S902), the micro computer 120 judges
that a calling finishing has been requested from the user (S903)
thus to finish a calling and to return to a calling waiting
state.
FIGS. 7 and 8 are flow charts showing a process for receiving a
calling in a state that the hands-free function has been set
according to the present invention, in which FIG. 7 is a flow chart
showing a process for receiving a call according to an embodiment
of the present invention and FIG. 8 is a flow chart showing call
allowing and refusing processes of FIG. 7.
When the hands-free function of the mobile communication terminal
has been set (S701), the micro computer 120 checks whether a
calling request message is received from an arbitrary originating
party (S702).
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 number exists (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.
If the calling party's telephone number exists in the mounted
telephone directory (S704), the micro computer guides a calling
party's name corresponding to 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 names at
the display unit 130 so that the user can precisely recognize the
originating party's name.
In case that the micro computer has not searched the originating
party's telephone number from the mounted telephone number
directory, a received telephone number is voice-guided through the
speakerphone 160 (S706).
After guiding the originating party's name or telephone 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 microphone 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 allowance`, or `Calling connection` to the microphone 140,
the 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).
When the calling between the user and the calling party has been
finished (S709), the micro computer 120 switches the mobile
communication terminal into a calling waiting state for sensing a
calling request message and outputs a voice message that the
calling has been finished to the speakerphone 160 (S710). Said
calling finishing process is performed as the same process as a
process shown in FIG. 9, thereby omitting its detail
explanations.
If the user inputs a voice message such as `NO`, `Calling refusal`,
or `Calling finish` to the microphone 140 when the calling party's
name or telephone number are guided by voice, the micro computer
120 transmits a response message for an impossible calling to the
originating party through a base station or a wireless switching
center and returns to a calling waiting state (S711). At this time,
the user can select a calling refusal by pressing an arbitrary key
such as a side key or a finishing key instead of a voice input, and
the micro computer 120 informs the user that the calling has been
refused by flickering a mute lamp or by using a voice message.
The process for a calling allowance or a calling finish S707 of
FIG. 7 will be explained with reference to FIG. 8.
When an originating party's name or a telephone number of an
originating calling are guided by voice (S705, S706), 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). However, if the user inputs a voice message relevant to 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).
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 when there is a car occupant next
the user, the user can hear the calling party's voice only by an
earphone.
First of all, at the time of calling with an arbitrary 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 connect a calling, and
inputs voice to a microphone provided at an earphone while hearing
the calling party's voice by the earphone under a state that
calling has been connected.
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
name or 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. When the 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
calling path in order to hear the calling party's voice by the
speakerphone 160 or the earphone.
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 number exists. Then,
the micro computer 120 guides the calling party's name or telephone
number to the user through an earphone. When the user inputs voice
for a calling allowance to a mike provided at the earphone or
presses an arbitrary key such as a calling key or a side key, the
micro computer 120 judges as a calling allowance state thus to
output the calling party's voice to the user through the earphone
and transmits the user's voice inputted to the microphone to the
calling party.
If it doesn't matter for a car occupant to hear calling contents or
the car occupant need not a calling when a calling from an
arbitrary originating party is 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 user's voice to the microphone 140.
That is, even if the secret calling has been set, if the user
releases the secret calling setting by pressing an arbitrary key
such as a side key, the micro computer 120 outputs the calling
party's 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.
As aforementioned, in the mobile communication terminal provided
with a hands-free function and the controlling method thereof
according to the present invention, the user can connect a calling
with a calling party by voice or can allow a calling by voice for a
calling from an arbitrary originating party. Accordingly, a risk
factor that the user has to press an arbitrary key or certify a
display unit while driving can be removed and an operation relevant
to a calling can be controlled by voice, thereby enhancing the
user's convenience.
Also, in the mobile communication terminal provided with a
hands-free function and the controlling method thereof according to
the present invention, a secret calling can be set according to the
user's need thereby to prevent an invasion of privacy.
As the present invention may be embodied in several forms without
departing from the spirit or essential characteristics thereof, it
should also be understood that the above-described embodiments are
not limited by any of the details of the foregoing description,
unless otherwise specified, but rather should be construed broadly
within its spirit and scope as defined in the appended claims, and
therefore all changes and modifications that fall within the metes
and bounds of the claims, or equivalence of such metes and bounds
are therefore intended to be embraced by the appended claims.
