Mobile Phone Patent Description
TECHNICAL FIELD
The present invention relates to text message service system for
the mobile phone display, and more particularly, to a system and
a method for creating text message wherein particular colors for
the characters or letters and the background on the mobile phone
display may be selected and characters may be made to blink.
BACKGROUND ART
Text message services [short message service(SMS) and long message
service(LMS)] are now prevalent for mobile phones. The text message
services such as SMS and LMS refer to services providing combinations
of characters and numerals made out by the users of mobile phones,
internet and personal computer communication, or various information
prepared by service providers through mobile phone communication
system. These message services are effectively used in financial
businesses such as notification of balance changes, particulars
of deposit and drawing, arrear information and new services; businesses
such as communications among staffs, order/distribution information,
event notice, customer management, employee calling; government
and public affairs such as taxation advice, training advice, event
notice; electronic commerce, auction and community activity, etc.
In addition, recently SMS businesses are carried out through Internet
Network or business private lines by SMS gateways or ASP service
providers.
Messages are generally transmitted by means of mobile phones in
the same manner as shown in the FIG. 1. When a user accesses a message
care menu as shown in the (A), out-going message menu appears, and
when he selects it, the menues of letter writing, mobile phone calling,
out-going message box arrangement appear as shown in the (B), and
menues such as writing of new sentences, calling of stored sentences
and transmission appear. When the user writes and transmits a message
by using a keypad, the message is received by a mobile phone of
a recipient via the message system.
But, as the text message of the conventional mobile phone is made
in monochrome and does not have the function of character blink,
it could not grab the user's interest, especially the young user's.
DISCLOSURE OF INVENTION
An object of the present-invention is to provide a system for creating
text message on mobile phone display with a message creating part
which has an additional part for creating message attributes of
character or letter colors, background colors and blink.
Another object of the present invention is to provide a method
for writing a text message having character and attribute information.
According to the present invention as described above, a system
for creating text message on mobile phone display, wherein attribute
information(character colors, background colors and blink) are added
to the message, comprises a means for creating a first message signal
by combining character codes which are outputted from a character
input means by a user and then inputted thereinto; a means for selecting
a character color to output the corresponding character color attribute
value selected among a plurality of color values by the user; a
means for selecting a background color to output the corresponding
background attribute value selected among a plurality of color values
by the user; a means for selecting a blink mode to output the corresponding
blink attribute value selected among a plurality of blink modes
by the user; a means for creating a second message signal by combining
each of the attribute values outputted from the selecting means
for character color, background color and blink function; and a
means for transmitting the first and the second message signals.
Preferably the first message signal comprises a header part including
ID or specific number and a message data part comprising ASCII values,
and the second message signal comprises a header part including
ID or specific number and an attribute information part of character
color, background color and blink.
With regard to transmitting the first and the second message signals
through the transmitting means, it is possible to transmit the second
message signal followed by the first message signal or to transmit
the first and second message signal at the same time.
In addition, the blink modes to be selected by the blink selecting
means preferably comprises a non-blink mode, a mode for blinking
in an odd number of the characters and a mode for blinking in an
even number of the letters.
Further, the background color selecting means preferably includes
a background scene selecting means which allows a user to select
one among a plurality of background scene indexes stored in a memory
thereby outputting a background scene attribute value for the selected
background scene.
Meanwhile, in accordance with the present invention, a method for
writing text message which comprises attribute information(character
colors, background colors and blink) on mobile phone display will
now be described. Especially, the method of the present invention
is made to be compatible with the conventional SMS in consideration
of characteristics of mobile phone display such as portable telephones.
ASCII codes are used as standard character notation forms in information
technology industry including codes which do not appear on the screen,
but are used for control. These codes are referred to as non-printable
codes or non-printable characters and the non-printable codes cover
the regions from 0x01 to 0x1F. These codes are used for control
thereby carrying out their functions in personal computers but do
have nothing to do in portable phones. Therefore, when the non-printable
codes are transmitted to a portable phone, they do not function
to show something on a screen and moreover no action occurs. Accordingly,
the system of the present invention has an advantage that it is
compatible with the conventional SMS system by using the non-printable
codes transmitting attribute information of colors, background scenes
and blink, etc.
According to the present invention, the method for writing text
message comprises the steps of forming text message information
in accordance with the character string inputted by a user; inserting
an identifier indicating the start of attribute information followed
by the character string; inserting attribute values(character blink
and character color value) which are selected in the region of non-printable
codes among ASCII codes.
The above method may further comprise the step of inserting an
index value which selects one among a plurality of background scenes
in addition to the message information.
Further, the attribute values are characterized in that they are
assigned to the rest 5 bits exclusive of the upper of 3 bits from
1 byte data row, while the character blink value among the attribute
values may be 1 bit and the character color value may be 2 bits.

BEST MODES FOR CARRYING OUT THE INVENTION
Hereinafter, preferable embodiments according to the present invention
will be described in detail with reference to the accompanying drawings.
Message Creating System
FIG. 2a illustrates in detail an embodiment of the present invention
by means of a user interface, wherein (a) when a user selects the
outgoing message 21 in the main menu window as usual, (b) the menu
for writing a color letter 22 appears apart from the menu for writing
a letter, (c) and then when the user selects the menu for writing
a color letter 22 and the menu for writing a new sentence 23, the
window for writing a color message comes out.
FIG. 2b is a view of an example of a window for writing color message
24 and shows that the message of "MBridge Systems, Inc."
is being written. There is a menu bar 25 at the bottom of the window
24 for writing a color message, which includes a "color"
menu 26 as well as the conventional menues such as Korean-English
conversion, capital character-small character conversion, special
characters, etc. When the "color" menu 26 is selected
on the menu bar 25, the window 27 for selecting colors as shown
in FIG. 2c appears.
In the window 27 for selecting colors, a color may be selected
from color 1 to color N for character color 28 and background color
29, respectively and a mode can be selected from mode 1 to mode
K for character blink 30 (hereinafter, referred to as "blink").
The blink modes can be varied as the designer pleases. For instance,
a non-blink mode, a mode for blinking in an odd number line, a mode
for blinking in an even number line and variation of blink rate,
etc. can be determined by the designer.
Selection of character color 28, background color 29 and blink
30 is executed by using an optional key installed in the phone.
For instance, for selecting character color 28 and background color
29, a scroll button on a side of the phone may be designed to scroll
from color 1 to color N in order to have a upper button 31 and a
lower button 32 select character color and background color, respectively.
Further, blink mode selection 30 is executed by using left-right
shifting buttons 33 and 34 on the keypad of the phone, as shown
in FIG. 2d. But, the selecting means are not limited to those buttons.
It would be obvious to those skilled in art that other keys in addition
to the scroll buttons 31 and 32 may be used for such use. Meanwhile,
a phone with a up-down-left-right cursor key 35 as shown in the
FIG. 2e may operate the window 27 for selecting colors by using
those keys.
The FIG. 3 shows a block diagram of an embodiment of message creating
system according to the present invention and FIGS. 4a and 4b show
the text message data format according to the present invention,
In the FIG. 3, a message creating part 41, a character inputting
part 43 and a memory 45 are components included in the conventional
message systems. The message creating system of the present invention
further comprises a message attribute creating part 47, a character
color selecting part 49, a background color selecting part 51, a
blink selecting part 53 and a transmitting part 55.
The memory 45 stores basic data for creating text message and message
attributes(character colors, background colors and blink).
The message creating part 41 creates a first message by combining
the character codes inputted from the character inputting part 43
with reference to the memory 45. The first message signal is created
by the same operation as the common SMS system and comprises ASCII
values. The (A) in the FIG. 4a shows a data format of the first
message signal. It should be noted that the data comprises a header
field including an ID and a specific number(Num), and a message
data field comprising ASCII values.
The message attribute creating part 47 creates a second message
signal by combining the attribute data which comprise the attribute
values selected from the blink selecting part 53 and inputted thereto
with reference to the memory 45. The attribute data may be created
by assigning a specific code for the respective attributes(character
color, background color and blink) and an ID for the respective
colors, respectively. The blink mode is designed to have a plurality
of modes previously and stored in the memory 45. The (B) in the
FIG. 4a shows a data format of the second message signal. The ID
or the specific number(Num) of the second message signal should
be identical with that of the header of the first message signal.
Hereinafter, an example of a method for creating information of
the first and the second message signal will be described in detail
with reference to the FIG. 4b. In the FIG. 4b, the sentence of "I
do love you" is given as an example of text message. For instance,
a background color and a character color may be selected among 8
(eight) colors, respectively, and the blink function may be selected
from 3 modes(non-blink, blinking in an odd number and blinking in
an even number). The system of the present invention needs additional
information for character color, background color and blink, while
the conventional SMS does not need such information as it has only
one kind of background color and character color, respectively,
and therefore the first message signal, namely the (A) in the FIG.
4b is identical with the conventional SMS message signal. That is,
the information data size needed in the present invention corresponds
to the respective message signal, while the data size needed in
the conventional message signal is 2 byte for a Korean character
and 1 byte for an English alphabet and ASCII code, respectively.
The FIG. 4b shows that for the one English alphabet of "I"
in the (B), namely the second message signal, assigned further are
3 bits for the background color, 3 bits for the character color
and 2 bits for blink(accordingly, the total 1 byte). As one English
alphabet needs one byte for the second message signal, it requires
one byte, and one Korean or other special character needs 2 bytes
and therefore the second message signal for it also needs 2 bytes,
which made by repeating twice 1 byte of the same content. In conclusion,
each character corresponds to the second message information of
the same size each other. Further, as the background and character
colors are possible to covers 8 kinds of colors, respectively, it
needs 3 bits per each one. But, as the background color does not
need to apply to the data after the first data, it is only needed
to be included in the upper 3 bits of the first 1 byte. As the blink
has 3 kinds of modes, it needs 2 bits per each one.
With reference to the FIG. 3 again, the transmitting part 55 has
the function of transmitting the first and the second message signals
and especially in the present invention, it transmits separately
each of the first and the second message signals stored in the memory
45 twice in the same way as the multiple-destination transmission.
That is to say, the first message signal is transmitted first as
a pure text data and then the second message signal is transmitted
as an information data corresponding to the text. In this case,
when they were transmitted by a conventional method, they should
be transmitted twice separately and therefore they should have the
same destination address.
Meanwhile, in the case of the SMS used in the CDMA environment,
a subscriber to "SK Telecom" adopting the cellular communication
system transmits his message by using the area of 80 bytes, and
a subscriber to "KTF" or "LG Telecom" with the
PCS system uses the area of 90 bytes, respectively. Accordingly,
the bigger user's area is needed to transmit attribute values for
background scene and characters in company with the character string
and therefore the first and the second message signals should be
transmitted twice separately. But, when radio network providers
have built a system for transmitting a large amount of message,
such as the LMS(Long Message Service), all the information of the
message may be transmitted at once but not twice separately. In
addition, one message including both of the character message signal
and the message attributes, can be created.
Hereinafter, operation of the reception will be described. The
receiving part of the other party's phone receives the first message
signals and stores them in the same manner as the conventional SMS
and then displays the stored data, wherein as it does not have any
information data for the second message signal, the message signals
are displayed in the same way as the conventional SMS. With regard
to the second message signals received later, they keep the address
for the end part of the data area of the first message signals.
Once the second message signals are received, all the header information
in the second message signals is cut off and only the pure message
attribute information is stored after the end of the address stored
previously. When the second message signals are completely stored,
the ends of the first message signals are checked. If the message
attribute information was checked to be stored therein, the text
message and attribute data are combined and the message having the
character color, background color and blink is displayed on the
phone display according to the present invention.
Aforementioned embodiment is not intended to limit the teaching
of the present invention, which should be judged by the scope defined
by the claims appended hereto. For instance, an application for
expanding the principle of the above background color selecting
means wherein a system for creating text message includes a background
scene selecting means which stores a plurality of background scenes
in the memory may be a modified embodiment without departing from
the scope of the present invention; once a user selects one among
a plurality of background scene indexes, outputting the background
scene attribute value of the selected background scene(so called,
a letter paper concept).
Method for Creating Text Message
A method for creating text message according to the present invention
is the method for creating text message including a character and
an attribute information by using the aforementioned text message
creating system.
Firstly, prior to describing an embodiment of the method for creating
text message, a data composition of text message of mobile phone
created according to the present invention will be described. The
FIG. 4c shows a text message comprising a character string, an identifier
and an attribute information and the FIG. 4d shows a text message
comprising a character string, an index value of background scene
and an attribute information.
The method for creating text message according to the present invention
relates to a method for creating text message as shown in the FIGS.
4c and 4d, wherein the attribute information includes a character
color value and a character blink value, and inputting of background
scene index may be optionally carried out.
Hereinafter, the method according to the present invention will
be described in detail with reference to the FIG. 5.
Firstly, when a user accesses a menu on a mobile phone display
to use message service and inputs a text message [21'], character
information is formed in accordance with the pre-determined rules
for the inputted character string [23'] by the built-in processor.
An identifier representing the start of an attribute information
after the end of the above character information is inserted [25'],
wherein the identifier refers to a bit informing that attribute
information such as character color, character blink and background
scene, etc. will follow the character information.
And then, character blink value and character color value [both
of the values will be defined as attribute information] are inserted
following the identifier [27']. But, these values are selected in
the non-printable area among ASCII codes which are not used for
a portable phone.
As the above attribute information use a non-printable code area
in ASCII codes, namely values only from 0x01 to 0x1F, it is possible
to use 5 bits of 1 byte(refer to the FIG. 6a). Therefore, according
to the present invention, in order to map attribute value in the
non-printable code, the upper 3 bits are usually maintained to be
binary numeral "0" and the other 5 bits are used for indicating
attribute values. Within the above 5 bits, 3 bits are assigned for
each attribute value for each character(1 bit for the character
blink value and 2 bits for the character color). Accordingly, the
character color is possibly selected among 2.sup.2=4 kinds of colors.
As the attribute value for each character is 3 bits, attribute
values are arranged in the same manner as shown in the FIG. 6b when
5 bits being possible to use in the non-printable code area is fully
utilized. That is to say, 3 bits among the rest 5 bits exclusive
of the upper 3 bits from 1 byte are arranged for the attribute value.
Although 3 bits are assigned to the attribute value in the FIG.
6b, it is not limited thereto and may be modified in accordance
with the needs for design by those skilled in art.
The process in the FIG. 5 may further comprise the step for inserting
background scene index values as shown in the text message data
format as shown in the FIG. 4. When 2 bytes are used for a background
scene value, it is possible to select one among 2.sup.10=1024 background
scenes.
As described above, a system and a method for creating text message
according to the present invention can provide interesting text
message services breaking from the conventional services providing
monochrome and prosaic message. They can enhance effects for distributing
advertisements and notices, etc. by effectively using the functions
of character colors, background colors and blink. Further, as they
include attribute information by using non-printable codes which
are not adopted in the mobile phones, it is compatible with the
conventional text message service.
