[0001] The present invention relates to a communication terminal apparatus and a control
method thereof, and more particularly, to the communication terminal apparatus having
a selection operation unit and the control method thereof.
[0002] Communication terminal apparatuses such as portable telephones that particularly
require portability are commonly used these days. In such communication terminal apparatuses,
a single input key has a single function assigned thereto. That is, separate keys
such as dial key, communication start key, communication end key, and redial key are
assigned independently.
[0003] There are some communication terminal apparatuses in which a plurality of functions
are assigned to a single input key. However, these functions are not selected by a
user but automatically selected according to the state of the communication terminal
apparatus. For example, a single input key is used for different operations according
to operation state or operation mode of the communication terminal apparatus such
as busy or waiting state.
[0004] However, if a single function is fixedly assigned to a single input key as described
above, the number of input keys inevitably increases with increasing functions of
communication terminal apparatus. In communication terminal apparatus using a single
input key for different functions according to the operation state or the operation
mode thereof, the number of input keys is not effectively reduced because functions
to be assigned are limited. For example, only a set of functions used only during
transmission or a set of functions used only during waiting state can be used for
such duplicate assignment.
[0005] Further, in a portable communication terminal apparatus such as portable telephone
that must have a small size, an increase in the input keys results in an increase
in the size of the apparatus, and thus there occurs a problem of degraded portability.
[0006] Further, the increase in the input keys makes it difficult for the user to select
an input key to be operated, which gives an impression that the equipment cannot be
operated easily. In addition, there occurs the problem that the user often presses
incorrect keys.
[0007] CA-A-2 012 199, upon which the precharacterizing portion of appended claim 1 is based, describes
a communications handset comprising a rotary switch on a side of the handset and a
display panel. The position, and direction of movement, of the switch is determined
and translated so as to cause highlighting of soft keys, or items, within a menu of
soft keys displayed on the display panel. Selection of a particular soft key is made
by depressing the switch when the desired soft key is highlighted.
[0008] It is an object of the present invention to provide a communication terminal apparatus
which reduces the above-mentioned problem.
[0009] It is another object of the present invention to provide a control method of communication
terminal apparatus which reduces the above-mentioned problem.
[0010] According to the present invention, there is provided a portable communication terminal
apparatus comprising:
a body;
transmitting and receiving means arranged in said body;
selection operation means arranged on said body operable by a user in a first direction
along a surface of said body and in a second direction into said body substantially
perpendicular to the first direction;
operation detection means for detecting an operation of said selection operation means
in said first direction and in said second direction;
storage means for storing data of a plurality of selection items which are hierarchically
arranged; and
display means for displaying said plurality of selection items read out of said storage
means;
characterized by
control means for controlling a position of a pointer to indicate a desired item out
of said plurality of selection items displayed on said display means when said selection
operation means is operated in the first direction and changing a display layout when
said selection operation means is operated in the second direction to change from
a display listing selection items of high hierarchy in a first format to a display
listing selection items of low hierarchy in a second format, said first and second
formats being recognizably different, wherein said control means causes said display
means to display a selection item of the high hierarchy on said display together with
items of the low hierarchy which are linked with said display selection item.

[0013] Preferred embodiments of the present invention will be described with reference to
the accompanying drawings. Incidentally, in the following embodiments, description
will be made by taking a portable telephone as an example of a communication terminal
apparatus.
[0014] First, the following description is about the portable telephone according to the
first embodiment of the present invention using Figs. 1 to 4.
[0015] Fig. 1 is a block diagram showing the integral part of the portable telephone according
to the first embodiment. Reference numeral 10 shows the portable telephone. Reference
numeral 11 is a controller for executing a terminal control program. Reference numeral
12 is a display unit composed of LCD (liquid crystal display) provided on a box, and
13 is a display driving circuit. The display data is supplied from the controller
11 to the display driving circuit 13, so that the display driving circuit 13 drives
the display unit 12.
[0016] Reference numeral 14 shows various operation unit provided on the box. The operation
information input by the operation unit 14 is supplied to the controller 11. Then,
the controller 11 controls various operations such as communication and display operations
based on the supplied operation information.
[0017] Reference numeral 15 shows a ROM (read only memory) for storing an operation program
for the controller 11. Reference numeral 16 shows a RAM (random access memory) which
is used for a working region when the program operation of the terminal control by
the controller 11 is executed.
[0018] Reference numeral 17 shows a baseband and RF unit, which modulates transmitted signals
and demodulates received signals. Reference numeral 18 shows an antenna for transmitting
and receiving.
[0019] The external construction of the portable telephone 10 is, for example, constituted
as shown in Fig. 2. The display unit 12 is provided on one of main surface of the
box to display various displays to the user. As the operation keys corresponding to
the operation unit 14, a soft key 1, a soft key 2, a soft key 3, a scroll knob 4,
and numeral/alphabet keys 5 used for dial call and character input are allocated.
On one side of the box, the scroll knob 4 is provided so that the user can rotary
operate. Further, On the other side of the box where the scroll knob 4 is not provided,
a rotatable arm portion 19 is provided. A microphone 20 is provided on the free side
of the arm portion 19. By turning upside of the arm portion 19 toward downside in
Fig. 2, the user can talk on the telephone. Further, on the upside of the main surface
of the box, a speaker 21 is provided in which the demodulated signal from the baseband/RF
unit 17 is supplied.
[0020] The soft keys 1, 2, and 3 have their functions varied according to the state set
by the scroll knob 4. The current function of each of the soft keys 1, 2, and 3 is
displayed in a function display region 12a of the soft keys in the display unit 12.
As shown in Fig. 2, the function display region 12a of the soft keys is located close
to the positions of the soft keys 1, 2, and 3, so that the user can easily understand
the current function of each of the soft keys 1, 2, and 3.
[0021] The scroll knob 4 is constituted as a rotatable knob in the up and down directions
indicated by the arrows in Fig. 2. When rotating the scroll knob 4, the user feels
that the scroll knob 4 is, for example, clicked so as to sense the rotational stages.
[0022] Fig. 2 shows a default state wherein the user does not operate the scroll knob 4.
In this state, the following words are displayed on the function display region 12a
of the soft keys to show the function of each of the soft keys 1, 2, and 3: the words
"SEND" meaning a call operation in response to the soft key 1; "END" meaning a communication
end operation in response to the soft key 2; and "CLEAR" meaning a clear operation
of input numerals in response to the soft key 3.
[0023] When the scroll knob 4 is rotated downward, the controller 11 regards that the default
state has shifted to the next state (assume that it is "state A") and that the functions
of the soft keys 1, 2, and 3 have been changed. As shown in Fig. 3, the following
words are displayed in the function display region 12a of the soft keys to show the
function of each of the soft keys 1, 2, and 3 in state A: the words "MUTE" meaning
a mute operation which mutes the sound output from the speaker 21 in response to the
soft key 1; "LOCK" meaning a key lock operation in response to the soft key 2; and
"REDIAL" meaning a redial operation in response to the soft key 3.
[0024] When the scroll knob 4 is further rotated downward in state A, the controller 11
regards that state A has shifted to the next state (assume that it is "state B"),
and further changes the functions of the soft keys 1, 2, and 3. As shown in Fig. 4,
the following words are displayed in the function display region 12a of the soft keys
to show the function of each of the soft keys 1, 2, and 3 in state B: the words "ALPHA"
meaning an alphabet input call operation in response to the soft key 1; "MEM" meaning
a memory call operation in response to the soft key 2; and "LIGHT" meaning a back
light operation in response to the soft key 3.
[0025] In state B in Fig. 4, when the scroll knob 4 is rotated upward for one level, the
state is returned to state A in Fig. 3. When the scroll knob 4 is further rotated
upward, the state is returned to the default state. In this manner, the controller
11 controls the display of the display unit 12 and the switch of each part based on
the input operation from the scroll knob 4.
[0026] If no operation has been performed for a specified length of time being in state
A or B, the controller 11 controls to automatically return to the default state shown
in Fig. 2
[0027] In this manner, aforementioned three states is selected by the scroll knob 4 and
the function of each of the soft keys 1, 2, and 3 are switched. Each of the soft keys
1, 2, and 3 thus can be used as the operation keys corresponding to the three functions.
[0028] As described above, the user can select the functions of the soft keys 1, 2, and
3 by the scroll knob 4, and the controller 11 controls the functions set according
to the current state, so that various operations can be executed with a small number
of keys. Therefore, it is possible to realize the portable telephone with high functions
as well as in miniature.
[0029] Furthermore, the functions which are used most frequently, such as send function,
end function, and clear function, are set in the default state, and the functions
which is relatively not used very much, such as alphabet input function, memory call
function, and back light function, are set in state B, so that the user can use the
portable telephone at a minimum of operation of the scroll knob 4. Therefore, the
simplicity of the operation can be improved.
[0030] The present invention is not only limited to the first embodiment, but various modifications
can be made thereto instead. For example, the states selected by the scroll knob are
not only limited to the three states (default, A, and B), but may be two, four or
more.
[0031] Next, the detailed description about the portable telephone as a communication terminal
apparatus according to the second invention of the present invention will be made
below.
Overall Construction
Body of Apparatus
[0032] The overall configuration and the circuit configuration of a portable telephone apparatus
31 are described using Figs. 5 and 6, respectively. The portable telephone apparatus
31 is composed of a main body 32 and an arm microphone 33 attached to its side rotatably
and freely opening or closing. Thus, by closing the arm microphone 33, the portable
telephone apparatus 31 can further be miniaturized.
[0033] The arm microphone 33 has the function for controlling on or off hook in response
to the opening and closing operation, and the function for disabling operations by
keys other than specified ones during the close state (referred to as a "key lock
function"). This key lock state can be released by opening the arm microphone 33.
This prevents erroneous transmission and receiving calls due to malfunctioning.
[0034] On the other hand, the main body 32 has various operation keys and a processing circuit.
On one of the main surface of the main body 32, a speaker 34 paired with the arm microphone
33, a display unit 35 composed of liquid crystal display elements, and a plurality
of operation keys 36 to which various functions are assigned are provided. Inside
of the main body 32, a controller 47 composed of a micro computer in which data is
input and output to and from the speaker 34, the display unit 35, and the plurality
of operation keys 36 is provided.
[0035] The controller 47 controls the display unit 35 via a display driving circuit 35A
to display information corresponding to the instruction input from the operation keys
36 using a font of an appropriate size.
[0036] The controller 47 operates based on programs stored in a ROM 48 and data read into
a RAM 49. The controller 47 also controls a transmitting/receiving circuit 40 to transmit
and receive information to and from other communication terminals via an antenna 41
connected to the transmitting/receiving circuit 40. The controller 47 has a card socket
43 connected thereto, and reads out all the management information on a subscriber
from a subscriber ID card 42 (in the second embodiment, a Subscriber Identity Module
(SIM) card 42) inserted into the card socket 43.
[0037] The program and the control data is stored in the ROM 48, by which the controller
47 executes and controls the operation of the portable telephone for displaying and
calling according to the second embodiment described later.
Operation key
[0038] The operation keys 36 provided on the main body 32 are now described. In the second
embodiment, the operation keys 36'are composed of the following ten keys: a power
supply key 36A, numeric keys 36B corresponding to "0" to "9", a "#" key 36C, a "*"
key 36D, a send key 36E; an end key 36F, a menu key 36G, a clear key 36H, a recording
key 36I, and a jog dial 36J. Eight operation keys 36A to 36H out of these keys are
located on one of the main surface of the main body 32, and the remaining two operation
keys 36I and 36J are located on side of the main body 32.
[0039] Main functions assigned to the respective operation keys are as follows. The power
supply key 36A is used to supply power to the internal circuit in the main body 32.
When the power supply key 36A is pressed once, the power is supplied to the apparatus,
and when the power supply key 36A is pressed twice, the power supply is turned off.
If the user has not input a PIN (Personal Identity Number) for thirty seconds after
the power was supplied by the power supply key 36A, the controller 47 detects the
circumstance and automatically turns off the power. In this manner, it is possible
to prevent the power from continuing to be supplied during malfunctioning.
[0040] Next, the description will be made about the ten numeric keys 36B. These ten numeric
keys 36B are used to input numbers and alphabets and to select the numbers. In this
embodiment, a plurality of alphabets are assigned to eight numeric keys "2" to "9"
other than the "0" and "1" so that alphabets can be input by these keys. For example,
"a" to "c" are assigned to a numeric key "2", "d" to "f" are assigned to a numeric
key "3", and the other alphabets are assigned to the other corresponding numeric keys.
[0041] When inputting alphabets, pressing a numeric key once enables the first character
to be input, pressing same key twice enables the second character to be input, and
pressing same key third times enables the third character to be input. The numeric
key 36B can also be used to select display items, and to execute an abbreviated dialing
function in which instruction is performed to start calling to the communicatee corresponding
to the numeric key by continuously pressing for a specified length of time (one second)
on the display screen of the telephone book list.
[0042] The send key 36E is used to instruct to start calling to a communicatee selected
from the display screen of the telephone book list, and to call the past dial history.
[0043] The end key 36F is used to instruct to end communication. Incidentally, communication
can also be ended by closing the arm microphone 33.
[0044] The menu key 36G is used to switch between an initial screen and a menu screen that
are displayed on the display unit 35. For example, assuming the screen shown in Fig.
7A is the initial screen, when the menu key 36G is pressed while this initial screen
is being displayed, the display can be switched to a menu screen as shown in Fig.
7B. Further, this screen can also be switched to another screen as shown in Fig. 7C
as if paging the screen, by using a scroll function described below. If, however,
the menu key 36G is pressed while a menu screen is being displayed, the display immediately
returns to the initial screen, whatever the menu screen may be. By using the clear
key 36H, the display can be returned to a previous screen as if pages were turned,
as shown in Figs. 8A to 8C.
[0045] The menu key 36G have a function as the only key for releasing the key lock state.
More specifically, as shown in Figs. 9A and 9B, even when the arm microphone 33 is
closed, the key lock state can be released to shift to a key active state by pressing
the menu key 36G.
[0046] On the other hand, as shown in Figs. 9B and 9C, if the menu key 6G is pressed while
the arm microphone 33 is closed and while a menu screen is displayed, the state returns
to the key lock state.
[0047] If no operation has been executed for thirty seconds since a menu screen was displayed,
the control 47 detects this and closes the menu screen to return to the initial screen.
In this case, if the arm microphone 33 is closed, the state returns to the key lock
state. This prevents from malfunctioning.
[0048] The recording key 36I is used to control the recording of conversations during communications
and the subsequent reproduction thereof, and is equipped on the upper surface of the
main body 32 and opposite to the arm microphone 33 so that the user can operate this
key by hand retaining the main body 32.
[0049] The following description is about the jog dial 36J having a central function out
of the ten operation keys. The jog dial 36J is provided on the upper part of one of
the side of the main body 32, near the speaker 34, which is located opposite to the
arm microphone 33. As in the recording key 36I, the user can operate the jog dial
36J by hand retaining the main body 32.
[0050] The jog dial 36J can be operated either in the circumferential direction or in the
radial direction, respectively. which is composed of a disc-shaped member (constituting
a rotary encoder) that rotates in the circumferential direction (indicated by arrows
"A" and "B") with an axis of rotation O as the central, a slide plate (not shown)
that can slide in the radial direction (indicated by arrows "C" and "D"), and a slide
switch SW, as shown in Fig. 10. The slide plate and the slide switch SW are subjected
to force in direction C. The slide switch SW is operated by which the rotary encoder
or the disc-shaped member is operated in the direction of D; pressed in the direction
of going into the main body 32.
[0051] The axis of rotation O is fixed to the slide plate. When the jog dial is pressed
in direction of the arrow D, the rotary encoder and the jog dial are slid en bloc
to press operate the switch SW, and the switch SW is switched to the "ON" state. The
controller 47 determines whether or not the jog dial 36J has been clicked, that is,
press operated by detecting the "ON" or "OFF" state of the switch SW based on the
output signal from the switch SW.
[0052] The rotary encoder slid en bloc with the slide plate is composed of two discs 36J1
and 36J2, as shown in Figs. 11A and 11B. The disc 36J1 is a movable member laminated
on the upper surface of the disc 36J2, and is equipped so that it can be rotated relative
to the disc 36J2 fixed to the slide plate. The movable disc 36J1 has a pair of facing
electrodes 36J21. When assembled, the pair of opposite electrodes 36J21 slidably contact
twenty pairs of facing electrodes 36J22 provided along the circumference of the disc
36J2. Incidentally, the facing electrodes 36J22 provided to the fixed side of disc
36J2 are formed in such a way that the positions of the inner and the outer circumferential
electrodes are slightly shifted.
[0053] Thus, when the jog dial is rotated in direction of arrow A shown in Fig. 11B, the
electric potential of the inner track side output from the facing electrodes falls
earlier to the earth potential, as shown in Fig. 12A. On the other hand, when the
jog dial is rotated in direction of arrow B in Fig. 11B, the electric potential of
outer the track side output from the facing electrodes falls earlier relative to the
earth potential, as shown in Fig. 12B. In this manner, the controller 47 detects which
electric potentials of the inner and outer track falls earlier, so that the rotational
direction of the jog dial 36J can be detected. In addition, the number of pulses output
from the outer track electrode is counted by a counter in the controller 47, the number
of rotations of the jog dial 36J thus can be detected.
[0054] Next, a typical example of operation of the portable telephone using the jog dial
36J is described. When a list screen is displayed on the display unit 35, the cursor
K displayed on the display unit 35 can be moved vertically by rotating the jog dial
36J circumferentially upward or downward, thereby one of the display items displayed
on the display unit 35 can be selected. In this state, pressing the jog dial 36J in
the radial direction, that is, in the direction of going into the main body 32 (hereinafter,
this operation is referred to as "clicking") makes it possible to input a read-out
command for detailed information concerning the item at which the cursor K is to the
controller 47.
[0055] In addition, in the case where the telephone book list is displayed, by pressing
the jog dial 36J continuously for a specified length of time, the user can instruct
the controller 47 to initiate a call. As described above, the rotary encoder of the
jog dial 36J press operates the switch SW, and it is detected whether or not the jog
dial 36J has been press operated for a specified length of time by the controller
47 based on the output signal from the switch SW. Incidentally, by rotating the jog
dial 36J in the circumferential direction during communications, the volume (reception
volume) can be adjusted. This is operated by detecting the direction and the number
of rotation of the jog dial 36J by the controller 47 to control volume output from
the speaker 34 based on the output signal output from the rotary encoder of the jog
dial 36J as shown in Figs. 12A and 12B. Also, the mute operation can be performed
by clicking the jog dial 36J during communications. Since the switch SW of the jog
dial 36J is press operated by being clicked the jog dial 36J, the controller 47 executes
the mute operation to the signal supplied to the speaker 34 based on the output signal
from the switch SW. Therefore, the mute operation is performed.
[0056] Fig. 13 is a flowchart showing a typical example of the use of the jog dial 36J during
an outgoing call.
[0057] By being clicked the jog dial 36J while a list screen such as the telephone book
or a redial screen is displayed, it is possible to display detailed information concerning
the selected item on the screen. If the jog dial 36J is clicked continuously for a
specified length of time, it can be initiated to call automatically to the communicatee
displayed where the cursor is. If the jog dial 36J is rotated to move the cursor K
upward or downward, it can be returned to the original list screen.
Call/Edition
Call
[0058] In this section, various calling methods provided for the portable telephone apparatus
31 are described.
Call from the Telephone Book List Screen
[0059] When the jog dial 36J is clicked while the arm microphone 33 is open, or while an
external microphone is connected to the main body 32, or while a hands free kit is
connected to the main body 32, the display on the display unit 35 is switched from
the initial screen shown in (A) of Fig. 14 to screen of the telephone book list shown
in (B) of Fig. 14.
[0060] As shown in Fig. 15, the telephone book list is composed of display section of call
frequency in which sets of address numbers "1" to "9" and registered communicatees
with high frequency of call are displayed, and display section of descending order
in which all the registered communicatees (including those already registered with
address numbers "1" to "9") in the descending order (for example, the alphabetical
order). The telephone book list is input by aforementioned numeric keys 6B, and is
stored in memory area in the controller 47 or in memory area in the RAM 49. The telephone
book list is read out from the memory area in the controller 47 or the memory area
of the RAM 49 based on the control signal from the controller 47 to display.
[0061] Immediately after the display is switched to the telephone book list, the cursor
K is located at the top of the items displayed on the display unit 35, that is, address
number "1". The downward rotation of the jog dial 36J in this state enables the cursor
K to sequentially move downward through the address numbers, such as "2", "3",...
On the other hand, while upward rotation of the jog dial 36J enables the cursor K
to sequentially move upward from the bottom item in the display sections of descending
order, such as Z, Y, X,...
[0062] The method for selecting a communicatee by moving of the cursor K includes not only
operation with the jog dial 36J, but also selection methods by inputting address numbers
or alphabets. If, for example, the telephone number of a communicatee is already registered
with any of the address numbers "1" to "9" and address number is known, it is possible
to make the cursor K jumped by pressing the numeric key corresponding to that address
number. An example is shown in Fig. 16.
[0063] If the list screen is an alphabetical display screen, the cursor K can be moved to
the corresponding alphabet by the "1" to "9" numeric keys. For example, pressing "2"
enables the cursor K to move to "a", and pressing "3" enables the cursor K to move
to "d". If there is no name starting with "d", the cursor K moves to a name staring
with "e" to display it. Further, if there is no name starting with "e", the cursor
K moves to the top of the subsequent names in the list.
[0064] Subsequent calling procedure is described assuming that the cursor K is to be moved
to the position of "Jack" registered with address number "5" as shown in Fig. 14C.
There is a plurality of calling procedures. Here, a method using the jog dial 36J
is described.
[0065] When the jog dial 36J is clicked in this state, the controller 47 switches the display
screen to the display section of detailed information based on the output signal from
the switch SW of the jog dial 36J, as shown in (D) of Fig. 14. When the jog dial is
further clicked for one second, the controller 47 counts continuation time of the
output signal from the switch SW of the jog dial 36J, as described above, and starts
calling. A data of a telephone number designated by the cursor K, for example, corresponding
to the address number "5", is read out from the memory area in the controller 47 or
the exclusive area in the RAM 49, and is transmitted from the transmitting/receiving
circuit 40, so that the calling operation is performed. At this point, the display
screen of the display unit 35 flashes, as shown in (E) of Fig. 14.
[0066] It is possible to change the communicatee while detailed information composed of
the name or the abbreviation and the telephone number is being displayed on the display
unit 35, as shown in (D) of Fig. 14, by rotating the jog dial 36J upward or downward.
If, for example, the jog dial 36J is rotated upward while the detailed information
is displayed on the display 35 as shown in (B) of Fig. 17, the display as (C) of Fig.
17 can be returned to the list screen belonging to the upper layer directly above
the detailed information screen. The position of the cursor K is, however, moved to
the item directly above the communicatee of which the detailed information has been
displayed. More specifically, the cursor K moves from "Ellis" with address number
"5" to "John" with address number "4", as shown in (C) of Fig. 17. The switching operation
of the display is performed by changing the read-out address to the memory area in
the controller 47 or to the exclusive area in the RAM 49 in which the telephone book
list is stored, or by changing the telephone book list read out from the memory area
in the controller 47 or the exclusive area in the RAM 49 by table.
[0067] As shown in (D) of Fig. 14, the function that, if no operation is operated for a
specified length of time, for example thirty seconds, in the state of being displayed
the detailed information, determines that a call will not be executed and closes the
telephone book list to return to the initial screen shown in (A) of Fig. 14, is provided.
The timer in the controller 47 counts or measures the elapsed time from when the jog
dial 36J or the keys 36A to 36H was last operated. If the timer in the controller
47 detects that the jog dial 36J or the keys 36A to 36H are not operated at the point
of time that thirty second has passed, the controller 47 outputs the control signal
to switch the display screen on the display 35. Therefore, even if a key capable of
initiating a call is inadvertently pressed when being carried the portable telephone
apparatus 31 in a bag with a detailed display screen displayed, an erroneous call
does not occur. This function also works when the list screen is being displayed.
[0068] In addition to the method for initiating a call from the screen of telephone book
list, there is another method of pressing the send key 36E while the display screen
shown in (D) of Fig. 14 is being displayed. This is a method that a call is initiated
after detailed information on the communicatee is displayed, and the portable telephone
apparatus 31 also provides a function of initiating a call directly from the list
screen. For example, if the send key 36E is pressed while the display screen shown
in (C) of Fig. 14 is being displayed, a call to a communicatee at which the cursor
K is positioned can be immediately initiated. A call can also be immediately initiated
by continuously pressing the numeric key corresponding to a communicatee for one second.
In these methods, the controller 47 detects the output signal from the send key 36E
or detects that the numeric key 36B is pressed for a specified length of time, and
controls the transmitting/receiving circuit 40 to initiate a call operation. The method
for detecting whether or not the numeric key 36B is press operated for a specified
length of time can be executed similar to the aforementioned method for detecting
whether or not the jog dial 36J is pressed for a specified length of time.
Menu Screen
Contents of Items
[0069] Finally, the menu screen displayed when the menu key 36G is press operated is described.
The menu screen has a hierarchical structure such that it can descend to the next
lower layer (submenu screens) by click operating the jog dial 36J. Here, Fig. 18 shows
menu screens W1 to W10 in the highest layer prepared for the portable telephone apparatus
31, and Figs. 19, 20, 21, and 22 shows submenu screens belonging to the lower layer.
[0070] The first menu screen W1 shown in Fig. 18 is used to edit the "Telbook (telephone
book)" and to set the "mode". By selecting of the "Telbook" item, a new telephone
number can be registered or registered contents can be edited. On the other hand,
if the "mode" item is selected, the display is switched to the menu screen shown in
(A) of Fig. 19 so that the setting conditions suitable for the use environment can
be selected. In this embodiment, four use environments are available for selection:
a "normal mode", a "pocket mode", a "silent mode", and a "driving mode".
[0071] For example, when the pocket mode is selected as shown in (B) of Fig. 19, the volume
of a ring can be maximized (ringer on) and further the key lock function can be activated.
Therefore, even if the portable telephone is used under the condition which is hard
to hear the ring, the user can catch the ring, and further the key inputs irrelevant
to operation can be rejected.
[0072] When the silent mode is selected in (A) of Fig. 19, the ring can be absorbed (ringer
off), and the display 35 is flashed to inform the user of an incoming call instead
of the ring. Therefore, the user can know of an incoming call without bothering people
around the user even in a train. A function for automatically ringing off the line
when no response is issued is also set during this mode.
[0073] When the driving mode is selected, the user can start communications automatically
upon an incoming call.
[0074] The second menu screen W2 in Fig. 18 is used to set a "SMS (short message function)".
This menu screen displays three items as shown in Fig. 23: "Delete", "Make Send",
and "Read". When "Make Send" is selected, it is possible to select at the lower menu
screen from the following items: the production of a new sentence to be transmitted;
the use of a pattern sentence; the use of a stored sentence that has previously been
transmitted; or the use of a stored sentence that has previously been received.
[0075] When "Read" is selected, it is possible to select similarly at the lower menu screen
from the following items: the storage or deletion of read contents; a reply through
a telephone; or a reply with a short message.
[0076] The third menu screen W3 in Fig. 18 is used to set a "Time" function. As shown in
Fig. 23, by selecting "set", "alarm", "sleep", or "wake up" in this menu screen, the
current time, the time to give an alarm, or turning on/off can be set.
[0077] The fourth menu screen W4 in Fig. 18 is used to set a "PLMN (Public Landit Mobile
Network)" function. This menu screen displays "Selection mode" and "Search" items.
The former is used to select whether the network should be set manually or automatically.
The latter is the function that automatically retrieves and displays currently available
networks.
[0078] The fifth menu screen W5 in Fig. 18 is used to set a "PIN (personal ID number)" function.
This menu screen displays "control" and "change" items. The former enables the setting
of whether or not the input of an ID number should be essential while operating, thus
enabling the setting of whether the network can be used only by particular people.
The latter enables an ID number to be changed.
[0079] The sixth menu screen W6 in Fig. 18 is used to set a "Forward" function. This menu
screen displays "Intrro (interrogation)", "Erase", and "Regist (registration)" items.
The "Intrro" item is used to inquire about a transfer service to the network, and
"Erase" and "Regist" are used to release and set a communicatee, respectively.
[0080] The seventh menu screen W7 in Fig. 18 is used to set "BarOut (outgoing)" function.
This menu screen displays items, "BOIC-exH (Barring of Outgoing International Calls
except those directed to the HPLMN Country)", "BOIC (Barring of Outgoing International
Calls)", and "BAOC (Barring of All Outgoing Calls)". Selection of each item sets the
corresponding outgoing function.
[0081] The eighth menu screen W8 in Fig. 18 is used to set an "BarCome (incoming)" function.
This menu screen displays items, "BICroam (Barring of Incoming Calls during Roaming
except those directed to the HPLMN Country)" and "BAIC (Barring of Incoming Calls)".
Selection of each item also enables to set corresponding incoming function.
[0082] The ninth menu screen W9 in Fig. 18 is used to set "Charge (charge)" information.
This menu screen displays "Reset" and "Check" items. The former is used to reset charge
information, and the latter displays the total charge.
[0083] The tenth menu screen W10 in Fig. 18 is a "Setting List" screen, in which the various
items shown in Fig. 21 can be set. An instruction for the screen next to this menu
screen causes a return to the first menu screen W1.
[0084] The setting list has five submenu screens in the lower layer, which are sequentially
described. The first submenu screen SW1 displays four items: "Call ID PRESENT", "Language
select", "ANY KEY ANSWER", and "1 Min BEEP". "Call ID PRESENT" is used to set a function
for transmitting the user's telephone number to a communicatee. "ANY KEY ANSWER" is
used to set a function which communications can be carried out even if any key is
pressed after an incoming call is received. "1 Min BEEP" is used to set a function
for informing the user of elapsed time by beeping every one minute during communications.
[0085] The second submenu screen SW2 displays four items: "Ringer Select", a "LowSignal
Warn (low signal level warning)" function, a "LowBattery Warn (low battery warning)"
function, and a "Ringer Volume". "Ringer Select" is used to select one ring sound
from three ring sounds as shown in Fig. 20. "Ringer volume" is used to select an appropriate
volume from three-level volumes as shown in Fig. 22.
[0086] The third submenu screen SW3 displays four items: "LCD Density" used for setting
brightness, "Change PIN2" used for changing a personal ID number, and "AutoVolume
CTRL" that automatically increase the volume when there are a large amount of background
noises, and "Noise Reduction".
[0087] The fourth submenu screen SW4 displays four items: "Clock Display" used for determining
whether or not the time should be displayed on the display 35, "SMS ServCenter" used
for changing the address of a service center, "SMS Enquiry" that determines whether
or not to show if a message has reached a communicatee, and "SMS Telematic" that determines
whether or not a short message should be sent to a facsimile terminal equipment.
[0088] The fifth submenu screen SW5 displays three items: "SMS Class" for weighing a short
message according to its importance, "Change Password" used for changing a password
that regulates incoming and outgoing calls within an additional service, and "Charge
ACMM" used for setting a function for restraining outgoing calls that exceed a certain
upper limit.
Scroll function
[0089] Next, a scroll function used for the portable telephone apparatus 31 to switch among
a plurality of menu or submenu screens belonging to the same layer at a high speed
is described in Figs. 24 and 25.
[0090] With this scroll function, when upward movement of the cursor K is instructed while
being located at the top of the items in each page, it is possible to switch the display
the preceding page, and also move the cursor K to the top of the newly displayed items.
In addition, when downward movement of the cursor K is instructed while being located
at the bottom of the items in each page, it is possible to switch the display to the
following page, and also move the cursor K to the bottom of the newly displayed items.
[0091] Therefore, the cursor K can be moved at a high speed even when an item displayed
on a very remote menu screen is to be selected.
Other embodiments
[0092] In the embodiment described above, the jog dial 36J having a rotation and a click
mechanisms is used as an input apparatus for moving the cursor K and deciding an item.
However; the present invention is not only limited to this, but is widely applicable
to input apparatus having other structure as long as the input apparatus is used in
which the operational directions for inputting the movement of the cursor K and confirming
a selected item are different.
[0093] For example, a jog shuttle in which the rotating angle is limited to a specified
value can be used. A track ball or a joy stick with a click mechanism can also be
used. Further, a slide switch with a click mechanism can be used. Even if these apparatuses
are used, it is possible to realize a communication terminal apparatus with a small
number of operation keys and a good portability, as in the second embodiment described
above.
[0094] Furthermore, in the embodiment described above, the jog dial 36J is operated in the
upward and downward directions to move the cursor K upward and downward, respectively.
However, the present invention is not only limited to this, but the jog dial 36J can
be operated upward and downward to move the cursor K rightward and leftward.
[0095] Furthermore, in the embodiment described above, if the jog dial 36J is operated upward
while detailed information from the telephone book list is being displayed, the display
screen is switched to a menu screen belonging to the higher layer, that is, the list
screen for names of communicatees, and the cursor is moved to the section displayed
above the communicatee whose detailed information has been displayed. However, the
present invention is not only limited to this, but, as shown in Fig. 25, detailed
information on the item directly above can be displayed when the cursor is operated
upward, while detailed information on the item directly below can be displayed when
the cursor is operated downward. In this case, the clear key 36H can be used to return
to the list screen.
[0096] Furthermore, in the second embodiment described above, when the jog dial 36J is operated
upward while the cursor K is positioned at the top of the items on a page, the cursor
K jumps to the top of the preceding page, whereas when the jog dial 36J is operated
downward while the cursor K is positioned at the bottom of the items on a page, the
cursor K jumps to the bottom of the following page. However, the present invention
is not only limited to this, but only the upward or the downward scroll function can
be operated.
[0097] In addition, the cursor K can be moved to the following page when the jog dial is
operated downward wherever the cursor K may be positioned on a page, whereas the cursor
K can be moved upward by one item when the jog dial 36J is operated upward. On the
contrary, the cursor K can be moved to the preceding page when the jog dial 36J is
operated upward wherever the cursor K can be located on a page, whereas it can be
moved downward by one item when the jog dial 36J is operated downward.
[0098] While there has been described in connection with the preferred embodiments of the
invention, it will be obvious to those skilled in the art that various changes and
modifications may be aimed, therefore, to cover in the appended claim all such changes
and modifications as fall within the scope of the invention.
