Description

  The present invention relates to a mobile communication terminal device such as a mobile phone or a PHS (Personal Handyphone System) terminal, or a communication terminal device such as a wired telephone terminal device. The present invention relates to a communication terminal device having a telephone directory search function for reading stored data.

  Generally, a telephone directory memory is built in a communication terminal device such as a mobile phone, a PHS terminal, and a wired telephone terminal. The phone book memory can be used to make calls to a desired party with few operations when combined with the memory dial transmission function, and the caller's name can be displayed when an incoming call is received when combined with the caller number notification function of the communication network. Yes, it is very convenient.

  By the way, when making a call using the above phone book memory, it is necessary to search stored data of a desired call destination from the phone book memory by operating a dial key. A search by number, a search by group number, or a search by reading kana is used (see, for example, Patent Document 1).

  Of these, the search by the memory registration number and the search by the group number are performed by entering the memory number or group number in which the dial data of the call destination is registered with the dial key. If the user memorizes the memory number or group number, it will be an effective search method, but if it is not memorized, the search must be scrolled in the order of the memory number. Time is required.

  On the other hand, what is searched for by reading a kana has the advantage that it can be searched in a shorter time than the input of a memory number because a search is made by inputting the reading kana of the other party by dial key operation. However, a toggle input method is generally used when inputting a reading kana with a dial key. For this reason, depending on the reading kana to be input, the number of key operations increases and the search operation becomes troublesome, and the search takes an unexpected amount of time.

JP-A-5-199309

However, as described above, the phonebook search function that has been used in the past requires a large number of operations to search depending on the number of registrations and the reading kana that you enter, which results in a long search time. have.
The present invention has been made paying attention to the above circumstances, and the object of the present invention is to make it possible to easily and quickly search desired storage data with a small number of operations regardless of the number of registered cases and reading pseudonyms. Therefore, it is intended to provide a communication terminal device that improves search performance.

  In order to achieve the above object, one aspect of the present invention is a communication terminal device having a telephone directory search function for searching a telephone directory memory and reading out desired stored data by operating a dial key. It is equipped with various means. That is, when a key for designating a line of the syllabary table is operated by one touch, stored data starting with the sound of the line corresponding to the operated key is read from the telephone directory memory and displayed on the display unit. In addition, when the storage data starting with the sound of the line corresponding to the key for designating the operated line is not stored in the telephone directory memory, the display unit displays data other than the storage data starting with the sound of the line. When the multi-function key is operated thereafter, the stored data of the lines other than the line in which the stored data is not stored is read from the telephone directory memory and displayed on the display unit.

Specifically, the following modes can be considered.
In the first aspect, when a key for designating a line of the syllable table is operated by one-touch operation, stored data starting with the sound of the line corresponding to the operated key is read from the telephone directory memory and displayed on the display unit. In this state, when the key for designating the stage of the 50-sound table is operated by one touch, the sound of the stage corresponding to the operated key is selected from the stored data corresponding to the row being displayed. The storage data that starts is selected and displayed on the display unit.

In the second mode, when a multi-function key is operated in a state where data other than the stored data starting with the sound of the line is displayed on the display unit, the line adjacent to the line in which the stored data is not stored. The stored data is read out from the telephone directory memory and displayed on the display unit.
For example, when the left key of the multifunction key is operated, the stored data in the row located on the left side of the row in which the stored data is not stored is read from the telephone directory memory and displayed on the display unit.
When the right key of the multi-function key is operated, the stored data in the row located on the right side of the row in which the stored data is not stored is read from the telephone directory memory and displayed on the display unit.

  That is, according to the present invention, it is possible to provide a communication terminal device capable of easily and quickly searching for desired stored data with a small number of operations regardless of the number of registrations, thereby improving searchability. .

Embodiments according to the present invention will be described below with reference to the drawings.
FIG. 1 is a circuit block diagram showing a configuration of a TDMA mobile phone terminal which is an embodiment of a communication terminal apparatus according to the present invention.

  In the figure, a radio carrier signal transmitted from a base station (not shown) via a radio channel is received by an antenna 1 and then input to a receiving circuit (RX) 3 via an antenna duplexer (DUP) 2. Then, the received local oscillation signal output from the frequency synthesizer (SYN) 4 is mixed and frequency-converted to a reception intermediate frequency signal. The received intermediate frequency signal is sampled by an A / D converter 6 including a low-pass filter and then input to a digital demodulation circuit (DEM) 7.

  The digital demodulation circuit 7 performs digital demodulation processing after establishing synchronization and bit synchronization for the transmission frame with respect to the digital reception intermediate frequency signal. The baseband digital demodulated signal obtained by this demodulation processing is input to a time division multiple access (TDMA) circuit 8 where the time slot addressed to itself is separated and extracted for each transmission frame. . Note that the synchronization and bit synchronization information for the transmission frame obtained in the digital demodulation circuit 7 is input to the control circuit 20.

  The digital demodulated signal output from the TDMA circuit 8 is subsequently input to an error correction code decoding circuit (CH-COD) 9 where error correction decoding processing is performed. Then, the error-corrected decoded digital demodulated signal is input to a speech code decoding circuit (SP-COD) 10 and subjected to speech decoding processing, whereby a digital received signal is reproduced. The digital reception signal is converted into an analog reception signal by the D / A converter 11 constituting the codec, and then supplied to the speaker 12 through a voice amplifier (not shown), and is output from the speaker 12 as a loud voice.

  On the other hand, the transmission voice of the speaker is collected by the microphone 13 and converted into a transmission signal, which is then input to the A / D converter 14 and sampled at a predetermined sampling period by the A / D converter 14. Thus, it is converted into a digital transmission signal composed of a sample pulse train. After the acoustic echo is canceled by an echo canceller (not shown), this digital transmission signal is input to a speech code decoding circuit (SP-COD) 9 where it is speech encoded.

  This voice-encoded digital transmission signal is input to an error correction code decoding circuit (CH-COD) 9 together with the control signal output from the control circuit 20, and is error-corrected encoded here. The error-encoded digital transmission signal is input to the TDMA circuit 8. The TDMA circuit 8 generates a transmission frame corresponding to the TDMA system, and performs processing for inserting the digital transmission signal into a time slot assigned to the own apparatus in the transmission frame. The digital transmission signal output from the TDMA circuit 8 is subsequently input to the digital modulation circuit (MOD) 16.

  The digital modulation circuit 16 generates a transmission intermediate frequency signal digitally modulated by the digital transmission signal. The transmission intermediate frequency signal is converted into an analog signal by the D / A converter 17 and then transmitted to the transmission circuit (TX) 5. Is input. As a digital modulation method, for example, a π / 4 shift DQPSK (π / 4 shifted, differentially encoded quadrature phase shift keying) method is used.

  In the transmission circuit 5, the modulated transmission intermediate frequency signal is mixed with the transmission local oscillation signal output from the frequency synthesizer 4, and thereby converted into a radio carrier frequency corresponding to the radio communication channel. The radio carrier signal is controlled to a predetermined transmission power level by a transmission power amplifier (not shown), and then transmitted from the antenna 1 to a base station (not shown) via the antenna duplexer 2.

  Reference numeral 21 denotes a key input unit (KEY) having a function key group including a dial key, a call key, a clear key, and a multifunction key. Reference numeral 22 denotes a liquid crystal display (LCD) or a light emitting diode (LED). The arranged display part (DISP) is shown. Further, 18 is a battery, and 19 is a power supply circuit. The power supply circuit 19 generates an operating voltage Vcc necessary for the operation of each part of the apparatus based on the output voltage of the battery 18 and supplies it to the above parts.

  By the way, this mobile phone terminal is provided with a telephone directory memory 23 called a personal folder. The telephone directory memory 23 is composed of, for example, an EEPROM, and dial data of a plurality of communication partners is registered in association with memory numbers. The dial data is composed of, for example, the telephone number of the communication partner and its attribute information. The attribute information includes a name, nickname, address, e-mail address, and the like.

The control circuit 20 uses a microprocessor as a main control unit. As a control function thereof, in addition to a normal control function related to incoming / outgoing calls and communication, a search mode designation control function 20a according to the present invention and two touches And a mode search control function 20b.
The search mode designation control function 20a sets the search control function of the control circuit 20 to the designated search mode when the user performs an operation of designating one of a plurality of search modes at the key input unit 21. To do. The search mode includes a reading kana search mode for searching the phone book memory 23 in accordance with the key input kana, a group search mode for searching the phone book memory 23 based on the key input group number, and 2 There is a touch search mode.

  The two-touch mode search control function 20b first assigns each row of “a” to “wa” in the syllable table to “1” to “0” of the dial keys, respectively, in a state where the above-described two-touch search mode is set. When the dial key is pressed in this state, the dial data starting with the sound of the line corresponding to the operation key is read from the telephone directory memory 23 and displayed on the LCD of the display unit 22. Next, each row of “A” to “O” in the Japanese syllabary table is assigned to “1” to “5” of the dial key, respectively, and when the dial key is pressed in this state, the row displayed above is displayed. From the dial data corresponding to the dial data, dial data starting with the sound of the step corresponding to the operation key is selected and displayed on the LCD of the display unit 22.

Next, a phone book search operation in the apparatus configured as described above will be described. 2 to 8 show an example of display of the operation procedure and search results.
(1) Search mode specification operation when starting from the menu
When the user operates the multifunction key on the standby screen (2a in FIG. 2) to select a menu and a personal menu, a personal menu screen (2b in FIG. 2) is displayed. In this state, when the “personal folder” is selected by pressing the enter key (middle), the telephone directory search mode is activated. At this time, the initial screen (2c in FIG. 2) of the “2-touch search mode” is first displayed on the display screen. When the user performs a mode selection operation using the multifunction key in this state, the display screen is displayed for each operation. The initial screen (2d in FIG. 2) of “Group search mode” and the initial screen (2e in FIG. 2) of “Yomikana search mode” are sequentially switched. In addition, if clear operation is performed in each screen, it will return to the said personal menu screen (2b of FIG. 2).

(2) Search mode specification operation when starting from the menu
When the user operates the call key on the standby screen (3a in FIG. 3), the phone book search mode is activated. At this time, the initial screen (3b in FIG. 3) of the “2-touch search mode” is first displayed on the display screen. When the user performs a mode selection operation using the multifunction keys in this state, the display screen is displayed for each operation. The initial screen (3c in FIG. 3) of “Group search mode” and the initial screen (3d in FIG. 3) of “Yomikana search mode” are sequentially switched. In addition, if clear operation is performed in each screen, it will return to the said standby screen (3a of FIG. 3).

(3) Operation when starting from the menu without registration in the personal folder
When the personal menu screen (2b in FIG. 2) is displayed and the “personal folder” is selected by pressing the enter key (middle), the telephone directory search mode is activated. However, at this time, if dial data is not registered at all in the telephone directory memory 23, a screen (4a in FIG. 4) is displayed that displays a message indicating that there is no registration. Then, when 2 seconds elapse in this state, the screen automatically returns to the standby screen (2a in FIG. 2).

(4) Operation when starting from a call without registration in the personal folder
Each display screen in the state in which the phone book search mode is activated, that is, the initial screen of “2-touch search mode” (3b in FIG. 3), the initial screen of “group search mode” (3c in FIG. 3), and “reading kana When the initial screen (3d in FIG. 3) of the “search mode” is displayed, even if the user performs any selection operation, if no dial data is registered in the phonebook memory 23, the registration is not performed. A message display screen (5a in FIG. 5) is displayed. Then, when 2 seconds elapse in this state, the screen automatically returns to the standby screen (2a in FIG. 2).

(5) Operation when a line designation operation is performed in the 2-touch search mode
In the state in which the 2-touch search mode is selected by the above-described search mode specifying operation (6a in FIG. 6), each row of “a” to “wa” in the syllable table is dialed as described above. The keys are assigned to “1” to “0”.

In this state, when the user presses any one of “1” to “0” of the dial key, dial data starting from the sound of “row” associated with the pressed key is selectively stored in the telephone book memory 23. And is displayed on the LCD of the display unit 22.
For example, when the dial key “1” is pressed, the dial data is read and displayed as shown in 6b of FIG. 6 starting from “A” in the “A” line. When the dial key “2” is pressed, the dial data is read and displayed as shown in 6c of FIG. 6 starting from “ka” in the “ka” row. Similarly, when the dial key “0” is pressed, the dial data is read and displayed as shown in 6d of FIG. 6 starting from “wa” in the “wa” row.

  Note that “other” is assigned to the dial key *, and when the dial key * is pressed, the dial data starting with characters other than “a” to “wa” is read from the telephone directory memory 23. Is displayed.

(6) Operation when there is no registered data in the row as a result of performing the above-mentioned “row” designation operation in the 2-touch search mode
Assume that the user presses the dial key “2”, for example, while the initial screen (7a in FIG. 7) of the “2-touch search mode” is displayed. In this case, normally, dial data is read out and displayed when starting from “ka” in the “ka” line as described above. However, if the dial data of the “ka” line is not registered, a screen (7b in FIG. 7) is displayed on the display screen to notify that there is no registered data in the “ka” line.

  Note that if the multifunction key is operated while the screen for notifying of registration is displayed, the display is switched to the display of dial data in the adjacent row. For example, when the multifunction key is operated while the “ka” line is displayed, the screen is switched to a screen displaying dial data of the “a” line or the “sa” line.

(7) Operation when the “column” designation operation is performed following the “row” designation operation in the 2-touch search mode
When the line dial data is displayed in response to the “row” designation operation, the control circuit 20 shifts to the “stage” search mode. That is, “A” to “O” levels in the syllable table are assigned to “1” to “5” of the dial keys, respectively.

In this state, when the user presses any of the dial keys “1” to “5”, dial data starting from the “dan” sound associated with the pressed key is selectively stored in the telephone book memory 23. And is displayed on the LCD of the display unit 22.
For example, when the user presses the dial key “2” in the state where the dial data of the “a” row is displayed as described above, as shown in FIG. When the dial key “3” is pressed, the dial data “a” row “u” is displayed as indicated by 8d in FIG. Similarly, when the user presses the dial key “4”, the dial data “a” line “e” stage is displayed as indicated by 8e in FIG. 8, and when the dial key “5” is pressed, the “a” line is displayed. It is displayed from the dial data of “O” row.

  If dial data starting from the sound selected by the “stage” designating operation using the dial key is not registered, the “stage” designating operation using the dial key is invalidated. For example, when the dial data “5” is pressed while the dial data of the “A” row is displayed, if the dial data starting from the “A” row “O” row is not registered, the dial The operation of the key “5” is invalidated, and the display screen does not change as indicated by 8f in FIG.

  As described above, in this embodiment, the two-touch search mode is provided as the phone book search mode. In the state in which the two-touch search mode is designated, first, each row of “a” to “wa” in the Japanese syllabary table is assigned to “1” to “0” of the dial keys, respectively. When pressed, the dial data starting with the sound of the line corresponding to the operation key is read from the telephone directory memory 23 and displayed on the LCD of the display unit 22. Next, each row of “A” to “O” in the Japanese syllabary table is assigned to “1” to “5” of the dial key, respectively, and when the dial key is pressed in this state, the row displayed above is displayed. Is selected from the dial data corresponding to the operation keys and displayed on the LCD of the display unit 22.

  Therefore, according to this embodiment, the user simply performs “one row operation” and “column” of the syllable table with the dial keys, and by the “row” and “column” designated by these key operations. Dial data starting with the specified sound is read from the telephone directory memory 23 and displayed. For this reason, even if the number of registrations in the telephone book memory 23 is very large, or whatever dialing data is to be searched, only a few operations with only two touches are always performed in a simple and short time. Dial data starting with a desired sound can be searched and displayed. Therefore, the searchability for the telephone directory memory 23 is greatly improved.

The present invention is not limited to the above embodiment. For example, although the above embodiment has been described for an example of a TDMA mobile phone terminal device, the present invention is not limited to this, and can be similarly applied to various communication terminal devices such as a CDMA mobile phone terminal device, a PHS terminal, and a wired phone terminal device.
In addition, the two-touch search control procedure, its contents, and the display form of the searched information can be variously modified and implemented without departing from the scope of the present invention.
