  If a key is pressed (YES at step 401), the key operation mode detection unit 601 determines whether the pressed key is the P1 key of the quick dial keys P1, P2, P3 or the P2 key. It is determined whether there is a P3 key (step 402, step 410, step 420).

  When the pressed key is the P1 key (step 402 YES), the control unit 6 stores the quick dial 1 registered corresponding to the P1 key in the key correspondence information table 12a of the memory unit 12 [FIG. Reference] and displays it on the LCD 11a (step 403).

  At the same time, the key operation mode detection unit 601 starts counting the key press timer T (step 404). Next, the key operation mode detection unit 601 monitors whether or not the key press has been completed (step 405), and continues the count of the key press timer T while the key is pressed (NO in step 405). . During this time, if the key press is finished (YES in step 405), the key operation mode detection unit 601 next determines whether the key press time is, for example, 2 seconds or more based on the count value of the key press timer T at that time. Determination is made (step 406).

  Based on the determination result, the operation mode setting control unit 602 sets the quick dial calling mode (step 407) when the key pressing time is shorter than 2 seconds (step 406 NO), and on the other hand, the key pressing time. If it is 2 seconds or more (step 406 YES), the telephone directory search mode is set (step 408).

  Similarly, when the pressed key is the P2 key (step 410 YES), the control unit 6 reads the quick dial 2 registered corresponding to the P2 key from the key correspondence information table 12a of the memory unit 12, This is displayed on the LCD 11a (step 411).

  At the same time, the key operation mode detection unit 601 starts counting the key press timer T (step 412). Next, the key operation mode detection unit 601 monitors whether or not the key pressing has been completed (step 413), and continues to count the key pressing timer T while the key is pressed (NO in step 413). . During this time, when the key pressing is finished (step 413 YES), the key operation mode detection unit 601 determines whether the key pressing time is, for example, 2 seconds or more based on the count value of the key pressing timer T (step 413). 414).

  Based on the determination result, the operation mode setting control unit 602 sets the quick dial calling mode (step 415) when the key pressing time is shorter than 2 seconds (step 414 NO), while the key pressing time. Is longer than 2 seconds (step 414 YES), the telephone directory search mode is set (step 408).

  Further, when the pressed key is the P3 key (step 420 YES), the control unit 6 reads the quick dial 3 registered corresponding to the P3 key from the key correspondence information table 12a of the memory unit 12, and this Is displayed on the LCD 11a (step 421).

  At the same time, the key operation mode detection unit 601 starts counting the key press timer T (step 422). Next, the key operation mode detection unit 601 monitors whether or not the key press has been completed (step 423), and continues the count of the key press timer T while the key is pressed (NO in step 423). . During this time, when the key press is finished (step 423 YES), the key operation mode detection unit 601 determines whether the key press time is, for example, 2 seconds or more based on the count value of the key press timer T ( Step 424).

  Based on the determination result, the operation mode setting control unit 602 sets the quick dial calling mode (step 425) when the key pressing time is shorter than 2 seconds (step 424), while the key pressing time. Is longer than 2 seconds (YES in step 424), the telephone directory search mode is set (step 408). If the pressed key is not one of the quick dial keys P1, P2, and P3 (step 402 → NO step 410NO → step 420NO), another processing operation corresponding to the pressed key (step 430). )I do.

  Next, processing operations in the quick dial calling mode among the operation modes set by the operation mode setting control unit 602 will be described with reference to the flowchart shown in FIG. When the quick dial calling mode is set by pressing one of the quick dial keys P1, P2, and P3 (step 407, step 415, and step 425 in FIG. 4), the key operation mode detection unit 601 then Then, it is monitored whether or not the call key 10a [see FIG. 2] among the various function keys in the operation unit 10 is pressed (step 501). If the call key 10a is pressed (YES in step 501), the call operation control unit 603 performs a call operation based on the quick dial information currently displayed on the LCD 11a (step 502). Then, after connecting with the other party, the operation shifts to a call operation (step 503).

  FIG. 6 is a diagram showing a transition of the information display mode on the LCD 11a when the quick dial is called. As shown in the figure, when the P1 key is pressed from the standby state (display 61), the quick dial 1 registered corresponding to the P1 key is read and displayed (display 62). Thereafter, when the call key 10a is pressed, a call is made based on the quick dial 1, and at the same time, a status display (display 63) indicating the call operation is displayed. After the other party responds to this call, the call is transferred and the status display (display 64) is performed. In this example, if the quick dial 1 is not registered after the P1 key is pressed, a message indicating no registration is displayed (display 65), and after 2 seconds, a status display (display 66) indicating standby is displayed. . Even when the P2 key or the P3 key is pressed from the standby state, the display control is similar to the above.

  As described above, in the mobile station PS of the present embodiment, when any of the quick dial keys P1, P2, and P3 is pressed, the pressing time is set in advance (2 seconds in this example). On the condition that it is shorter, the calling operation is performed based on the quick dial information registered corresponding to the pressed key among the quick dial keys P1, P2 and P3. That is, each of these quick dial keys P1, P2, P3 functions as an original quick dial key by a short press within a range not exceeding 2 seconds, for example.

  Next, processing operations in the phone book search mode among the modes set by the operation mode setting control unit 602 will be described with reference to the flowchart shown in FIG. When the phonebook search mode is set by pressing one of the quick keys P1, P2, and P3 (step 408 in FIG. 4), the search operation control unit 604 in the control unit 6 first stores in the memory unit 12. After specifying the phone book registered in the phone book registration table 12b (see FIG. 3B) as a search target, the line search counter n is initialized (step 701).

  Subsequently, the key operation mode detection unit 601 monitors whether or not a key is pressed on the operation unit 10 (step 702). If it is recognized that the key is pressed (YES in step 702), the key operation mode detection unit 601 determines that the pressed key is the P1 key of the quick dial keys P1, P2, and P3. Or the P2 key or the P3 key (Step 703, Step 710, Step 720).

  When the pressed key is the P1 key (step 703 YES), the search operation control unit 604 accesses the telephone book registration table 12b and corresponds to the value of the row search counter n in the telephone book registration table 12b. The registered item (telephone number) belonging to the line (any one of the lines a to w) is searched forward by one item (step 704), and the retrieved telephone number is read from the telephone directory registration table 12b to obtain the LCD 11a. (Step 705).

  Thereafter, the key operation mode detection unit 601 monitors whether or not the call key 10a among the various function keys in the operation unit 10 has been pressed (step 706). Here, when the call key 10a is not pressed (NO in step 706), the process returns to the processing after step 702, and monitoring of pressing of the next quick dial keys P1, P2, P3 is continued. Each time the P1 key is pressed among the quick dial keys P1, P2 and P3, the telephone numbers in the telephone directory registration table 12b are searched one by one by the method described above, and this is searched for on the LCD 11a. Display and continue searching while checking.

  During this time, for example, when the P3 key is pressed (YES in step 710), the search operation control unit 604 searches the registered items (phone numbers) in the phone book registration table 12b one by one in order. Thereafter, the registration items (telephone numbers) belonging to the line (any one of lines a to w) corresponding to the value of the line search counter n in the telephone directory registration table 12b are in the reverse order from when the P1 key is pressed. The retrieved telephone numbers are read from the telephone directory registration table 12b and displayed on the LCD 11a (step 705).

  On the other hand, if the P2 key is pressed during the key press monitoring (YES in Step 720), the search operation control unit 604 has previously selected the line corresponding to the value of the line search counter n (any one of lines A to W). Items that have been searched one by one for each registered item (telephone number) belonging to are subsequently searched for, for example, from line A to line C.

  Specifically, the search operation control unit 604 adds “1” to the row search counter n when the P2 key is pressed (step 721), and then the value of the row search counter n is “10”. It is determined whether or not this is the case (step 722). If the value of the row search counter n is “10” or more (step 722 YES), the value of the row search counter n is changed to “1” (step 723).

  On the other hand, if the value of the row search counter n is smaller than “10” (step 722 NO), first, the row search management table 12c [refer to FIG. For example, “sa line” corresponding to (n = 3) is specified, the head phone number of the bank in the phone book registration table 12b is searched (step 724), and the searched phone number is registered in the phone book. The data is read from the table 12b and displayed on the LCD 11a (step 705).

  By the processing from step 720 to step 724, for example, the item in the phone book registration table 12b is searched by the forward search (step 704) or reverse search (step 711) for each item using the P1 key or the P3 key. If the P2 key is pressed after searching for the phone number of “Akagi” to which it belongs, the process proceeds to search for the phone number of “Kato” at the head of the line skipped by one line from line A. Further, the above-described line search is continued by the operation of the P2 key. After the search for the telephone number of “Wada” in the Wa line, when the P2 key is further pressed, the line search counter n is set to (n = 10). In this way (n = 1) and incremented (step 723), the telephone number of “Aoyama” at the head of the first line A is searched.

  When the call key 10a is pressed by the key operation mode detection unit 601 after the forward search, reverse search or line search using the quick dial keys P1, P2 and P3 as described above (step 706 YES), the control unit 6 performs a call operation based on the telephone number currently displayed on the LCD 11a as a search result of the telephone directory (step 707), and after connecting to the other party, shifts to a call operation. (Step 708).

  FIG. 8 is a diagram showing transition of the information display mode on the LCD 11a at the time of searching the telephone directory. As shown in the figure, when the P1 key is pressed for a long time in the standby state (display 81), it shifts to the phone book search mode and any phone registered in the phone book (phone book registration table 12b). The number is read and displayed (display 82). Thereafter, when the P1 key is continuously pressed, the telephone numbers in the telephone directory are retrieved and displayed one by one in the order of the names of Iueo (displays 83 and 84). If the P3 key is pressed during the search, the telephone numbers in the telephone directory are searched and displayed one by one in the reverse order to that when the P1 is pressed (display 85). Furthermore, when the P2 key is pressed from that state, the search is shifted from the search for the phone number of the previous line, for example, to the search for the first phone number of the next line that has been skipped by one line. A telephone number is displayed (display 86). Even when the P2 key or the P3 key is pressed for a long time from the standby state, the mode shifts to the telephone directory search mode and the display control is performed in the same manner as described above. In addition, two telephone numbers (for example, a home telephone number and a PHS telephone number) can be registered for one name in the telephone directory, and when two telephone numbers are stored, By pressing a predetermined key, the display of the two numbers can be switched (display 89).

  Next, a modified example of the high-speed search using the P2 key will be described with reference to the flowchart shown in FIG. In the above embodiment, the telephone numbers in the telephone directory are captured in association with the index information of the A to W lines, and each telephone belonging to the line corresponding to each of the index information according to the key operation of the P1 key or the P3 key. Each number is searched one item at a time, for example, in the order of Iueo or vice versa, and each time the P2 key is operated, the phone number jumps to the phone number in the first line of the index information before or after the currently searched index information. In this modification, the phone number registered in the phone book is captured in relation to the registered number, and the phone book is searched according to the key operation of the P1 key or the P3 key. For example, each telephone number is searched one by one in the order of registration numbers or in reverse order, and each time the P2 key is operated, the number of registration numbers (N) set in advance is set. Jump to the registration number, and performs N number unit search to find the phone number of this flew ahead.

  In the mobile station PS according to this modification, when the telephone directory search mode is set by pressing any of the quick keys P1, P2, and P3 (step 408 in FIG. 4), the search operation control unit 604 in the control unit 6 is set. First, after specifying the phone book registered in the phone book registration table 12b (see FIG. 3B) in the memory unit 12 as a search target, a jump number search counter n (not shown) is initialized. (Step 901).

  Subsequently, the key operation mode detection unit 601 monitors whether or not a key is pressed on the operation unit 10 (step 902). If it is recognized that the key is pressed (YES in step 902), the key operation mode detection unit 601 determines that the pressed key is the P1 key of the quick dial keys P1, P2, and P3. Or the P2 key or the P3 key (step 903, step 910, step 920).

  When the pressed key is the P1 key (YES in step 903), the search operation control unit 604 accesses the phone book registration table 12b and sets the count value n of the jump number search counter n in the phone book registration table 12b. The registration items (phone numbers) belonging to the range of the corresponding skip registration number (N) are searched one by one in the order of the registration numbers (step 904), and the searched phone numbers are read from the phone book registration table 12b to be displayed on the LCD 11a. (Step 905).

  Thereafter, the key operation mode detection unit 601 monitors whether or not the call key 10a among the various function keys in the operation unit 10 is pressed (step 906). If the call key 10a is not pressed (NO in step 906), the process returns to step 902 and the subsequent steps to continue monitoring the pressing of the next quick dial keys P1, P2, and P3. Each time the P1 key is pressed among the quick dial keys P1, P2 and P3, the telephone numbers in the telephone directory registration table 12b are searched one by one in the order of registration numbers by the method described above. The search is continued on the LCD 11a while confirming.

  During this time, for example, when the P3 key is pressed (YES in step 910), the search operation control unit 604 searches for the telephone numbers in the telephone directory registration table 12b in the order of the registration numbers until then. One registration item (telephone number) belonging to the range of the number of skip registration numbers (N) corresponding to the count value n of the skip number search counter n in the telephone directory registration table 12b is in the reverse order to the time when the P1 key is pressed. Each search is performed (step 911), and the retrieved telephone number is read from the telephone directory registration table 12b and displayed on the LCD 11a (step 905).

  On the other hand, if the P2 key is pressed during the key press monitoring (YES in Step 920), the search operation control unit 604 skips the number of skipped registration numbers (N) corresponding to the count value n of the skip number search counter n so far. Items that have been searched for in the order of registration number or the reverse order of each registration item (phone number) belonging to the range are set in advance, for example, from registration number 20 to registration number 30. The telephone number corresponding to the previous registration number is searched for the number of skipped registration numbers (N).

  Specifically, when the P2 key is pressed, the search operation control unit 604 adds “1” to the jump number search counter n (step 921), and then the value of the jump number search counter n is “20”. It is determined whether or not it is greater than or equal to (step 922). If the value of the flight number search counter n is “20” or more (step 922 YES), the value of the flight number search counter n is changed to “n = 1” (step 923).

  On the other hand, when the value of the flight number search counter n is smaller than “20” (step 922 NO), [(n × 10) +1] is calculated, and the registration corresponding to the calculated value in the telephone directory registration table 12b. The telephone number registered corresponding to the number is retrieved (step 924), and the retrieved telephone number is read from the telephone directory registration table 12b and displayed on the LCD 11a (step 905).

  By the processing of step 920 to step 924, for example, by the registration number order search (step 904) or the registration number reverse order search (step 911) for each item using the P1 key or the P3 key, the phone book registration table 12b When the P2 key is pressed after searching for the phone number of “Kato” in the registration number “3”, it is calculated based on the value of the flight number search counter n (n = 1) at this time [(1 × 10) + 1 = 11] The process proceeds to the search for the telephone number of the other party registered for the registration number. Further, the number skip number “10” as described above is continued by the operation of the P2 key, and after the (2 × 19) + 1 = 191] number after the P2 key is operated 19 times. If the P2 key is further pressed while searching for the telephone number corresponding to the registered number, the flight number search counter n becomes (n = 20) and is incremented to (n = 0) (step 923). Thus, [(n × 10) + 1 = 1] number, that is, the telephone number of “Aoyama” at the head of the telephone directory registration table 12b is searched.

  As described above, after the search using the quick dial keys P1, P2, and P3, the registration number order search, the reverse registration number search, or the skip search by the number of registration numbers (N), the key operation mode detection unit 601 uses the call key. When 10a is pressed (YES in step 906), the call operation control unit 603 in the control unit 6 performs a call operation based on the telephone number currently displayed on the LCD 11a as a search result of the telephone directory (step 907). ) After connecting with the other party, the operation proceeds to a call operation (step 908).

  As described above, the quick dial keys P1, P2, and P3 function as an original quick dial key by, for example, a short press of a range not exceeding 2 seconds, and by a long press of a time exceeding 2 seconds. It also functions as a key to start the phone book search mode. In this telephone directory search mode, for example, the P1 key can be used as a forward search key, the P3 key can be used as a reverse search key, and the P2 key can be used as a multiple item skip search key.

  By providing a high-speed search key equivalent to the above P2, it has become possible to search for items that could only be searched for one item at a time by skipping multiple items. For example, a huge number of phone numbers such as 200 people can be registered. Even the phone book can be displayed on the telephone number of the intended destination very quickly by the high-speed search.

  Furthermore, in the present invention, whether or not a function that can make a call immediately using the telephone number by pressing the call key 10a while the searched telephone number is displayed is supported. It can also contribute to improving the key operability at the time of calling or shortening the calling operation time.

  In the above embodiment, an example is shown in which the quick dial calling mode or the telephone directory search mode is set according to the pressing time of the quick dial keys P1, P2, and P3. The number of times may be monitored, and each operation mode may be set according to whether the button is pressed once or a plurality of times.

  In addition, although the telephone directory is taken as an example of the search target, the present invention can be applied to a search for all information item registration means in which various information items are registered.

  Further, in any of the high-speed search shown in FIG. 7 and its modification (FIG. 9), the number of phone numbers that can be registered, the number of lines to be skipped, or the number of registered numbers (N) can be arbitrarily set. Moreover, it can be configured such that the flying direction can be both forward and reverse. Further, in the modified example shown in FIG. 9, since the number jumps to the registration number [(n × 10) +1], for example, according to the number n of operations of the P2 key for skipping search, the destination registration number is fixed (No. 11, 21,...) However, if necessary, the registration number currently being searched can be modified to jump to the registration number of [(n × 10) +1] ahead. it can. Further, the present invention is not limited to PHS, and it is needless to say that the present invention can be applied to other mobile radio terminals such as PDC (Personal Digital Cellular) and pager (Pager).

  The present invention can be applied to high-speed retrieval of a plurality of information items registered in an information registration unit in mobile radio terminals such as PHS mobile terminals, PDCs, and pagers.
