Description

  The present invention relates to a search method and apparatus in a mobile terminal, and more particularly to a search method and apparatus using position information.

  In mobile terminals such as mobile phone terminals and digital cameras, various data stored in a built-in memory are searched. For example, in a mobile phone terminal, when inputting characters, word data is searched based on readings input by the user, displayed as candidate words, and selected by the user. Specifically, in a mobile phone terminal having a predictive conversion function (word prediction) that predicts and presents an input word with one initial letter, for example, when “ha” is input, word data input in the past is searched. In addition, “Hull”, “Haruka”, “Flower”, “Haruga”, etc. are displayed as prediction candidates in order of frequency of use and are selected.

  On the other hand, Patent Document 1 proposes an idea of using position information where a terminal exists when inputting information in a portable terminal. In this patent document 1, when a digital camera which is a portable terminal is set to an information input mode and a character “to” is input, for example, the character and the current position of the terminal are sent to the information server. Using the starting word as a key, “Tokyo”, “Tokyo”, “Tokyo”, etc. are searched from the database as input candidate information and returned to the mobile terminal, while the word “city” starting with “to” from the internal dictionary also in the mobile terminal “Bird”, “Tomato”, “Tokyo Tower”, etc. are searched and displayed on the input screen together with the input candidate information returned from the information server, enabling selection by the user.

  FIG. 4 is a conceptual diagram of the process of rearranging the display order of the predictive conversion search result and the phone book search result, FIG. 5 is a flowchart showing an example of the setting process of the word data by region to be referred to, and FIG. FIG. 7 is a flowchart showing an example of the rearrangement process of the display order of the phone book search results. Hereinafter, the operation of this embodiment will be described with reference to the drawings.

<Predictive conversion of character input>
When the position of the mobile phone terminal 100 changes due to the movement of the user who owns the mobile phone terminal 100, this is detected on a network basis, and the location information of the mobile phone terminal 100 is updated. The location information is sent to the mobile phone terminal 100. Here, a method for positioning the position of a mobile phone terminal on a network basis includes a method based on the cell position of a base station where the mobile phone terminal is located, a time difference between radio waves reaching the mobile phone terminal from the base station, There are methods that use orientation and the like.

  The control unit 103 of the mobile phone terminal 100 that has received its own location information by the wireless unit 102 through the antenna 101 stores the updated location information in the memory 106 and searches the regional word data unit 302 in the memory 106. Then, it is checked whether or not there is region-specific word data corresponding to the updated position information (S501, S502). This is because, for example, the position information included in the section is recorded at the head of each region-specific word data 302-1 to 302-5, and it is checked whether there is a section in which the updated position information is recorded. Is possible.

  Then, if the corresponding region-specific word data exists, it is set as region-specific word data to be referred to when performing predictive conversion for character input (S503). This is done by, for example, storing the start address and the end address of the corresponding region-specific word data in a table that records the start address and the end address of the region-specific word data to be referred to when performing predictive conversion of character input. Do. On the other hand, if the corresponding regional word data does not exist, the control unit 103 requests the server device (not shown) of the network 107 to download the relevant regional word data through the wireless unit 102 and the antenna 101, and is necessary. The regional word data is downloaded (S504). The downloaded region-specific word data is stored as new data in the region-specific word data section 302 (S505), and is set as region-specific word data to be referred to when performing predictive conversion for character input (S503).

  Next, a method for controlling the display order of the search results of the character input predictive conversion using the regional word data set as described above will be described.

  As shown in FIG. 2, on the character input screen, the user inputs an appropriate character to the text input unit 201 of the display unit 104 with the key 105 (S601 in FIG. 6), and presses the key for starting the predictive conversion. Then (S602), the control unit 103 searches the word data unit 301 of the memory 106 for a word predicted by the input character (S603), and at the same time, input from the set regional word data. The word predicted by the character is searched (S604). Then, the word retrieved from the word data unit 301 is compared with the word retrieved from the regional word data (S605), and the word retrieved from the word data unit 301 matches the regional word data. The words searched from the word data unit 301 are rearranged so that the displayed words are preferentially displayed (S606) and displayed on the prediction conversion display unit 202 of the display unit 104 (S607). On the other hand, when the same word does not exist in the regional word data of the memory 106, the search result of the word data unit 301 is displayed on the prediction conversion display unit 202 of the display unit 104 in the original order (S607).

  For example, as indicated by reference numerals 401 and 402 in FIG. 4A, each of the words A, B, C, D, and E (where A to E are one word from the word data portion 301, for example, A Is love, B is tomorrow, C is a partner, D is Asakusa, and E is Akihabara), and D and E are searched from the set regional word data. A to E are arranged in descending order of use frequency, but after rearrangement, the words D and E existing in the regional word data are rearranged so that they are displayed first. This makes it possible to increase the priority of the display order of the words related to the area where the mobile phone terminal 100 exists even if the words are used less frequently.

<Search phone book>
Next, the operation when searching the phone book will be described.

  When the phone book search is activated, the user inputs a keyword for searching the phone book using the key 105 (S701), and the key for starting the phone book search is pressed (S702), the control unit 103 stores the phone book search. Phonebook data including the keyword is searched from the phonebook data section 303 (S703). Here, as a keyword, a part of a name, a part of a reading, a part of a telephone number, a part of an e-mail address, a group number, and a line (in order of Akasana) can be used. At the same time, the control unit 103 searches the area code data unit 304 of the memory 106 using the location information of the mobile phone terminal 100 received from the network 107 through the antenna 101 and the wireless unit 102 as a key, and the mobile phone terminal 100 is currently present. The area code of the area is acquired (S704). If there is only one phone book data retrieved from the phone book data unit 303 (No in S705), the one phone book data is displayed on the display unit 104. If there are a plurality of cases, the area code of the current location is compared with the area code of the current location retrieved from the area code data section 304 (S707). The plurality of searched phone book data is displayed on the display unit 104 in the original order. However, if there is a match, the phone book data having the area code of the current location is rearranged to be displayed with priority over the other phone book data (S708) and displayed on the display unit 104 (S706). ).

  For example, as indicated by reference numerals 411 and 412 in FIG. 4B, from the phone book data section 303, phone book data P, Q, R, S, and T (where each of P to T is one phone book data) And the area code of the telephone number included in it is retrieved from the area code data section 304, assuming that P is 06, Q is 042, R is 072, and S and T are 03). If the registered area code is 03, the phone book data P to T are arranged in order of frequency of use in the state before the rearrangement, but after the rearrangement, the area code 03 of the current location is held. The phone book data S and T are rearranged so that they are displayed first. As a result, even if the phone book data is infrequently used, the phone book data having the area code of the area where the mobile phone terminal 100 is present is displayed with priority.

  Next, the effect of the present embodiment will be described.

  According to the present embodiment, when a character is input in a mobile phone terminal, a word related to the region is ranked in the search result of the predictive conversion based on the position information of the mobile phone terminal 100 received from the network 107 through the antenna 101. Can be displayed. For this reason, when creating an e-mail with contents related to the current location, even words that are not familiar to the user can be easily selected from the search result of the predictive conversion, and characters can be input quickly.

  Further, according to the present embodiment, when searching for a phone book in a mobile phone terminal, the same city code as the area code of the area where the user is currently located, based on the location information of the mobile phone terminal 100 received from the network 107 through the antenna 101. The telephone directory data of the area code telephone number can be displayed at the top.

  Although the embodiments and examples of the present invention have been described above, the present invention is not limited to the above examples, and various other additions and modifications can be made.

  For example, in the above embodiment, the position information of the terminal is detected on a network basis, but the position may be measured on the terminal side by GPS or the like.

  In the above embodiment, the predictive conversion of word data is taken as an example as a search at the time of character input. In this case, a kana-kanji conversion dictionary is used instead of the word data unit 301, and a regional kana-kanji conversion dictionary is used instead of the regional word data unit 302, and the control unit 103 selects candidates for kanji corresponding to the input kana. Is searched from the Kana-Kanji conversion dictionary, and at the same time, the Kanji-Kanji conversion dictionary for each region corresponding to the input Kana is searched from the Kana-Kanji conversion dictionary for each region. In another kana-kanji conversion dictionary, the same sort is displayed based on whether or not the same is searched. Thus, for example, when “Sawara” is entered and kana-kanji conversion is instructed, even if “Sunahara, Sakai, Sawara, Sahara” is output in order of frequency of use from the kana-kanji conversion dictionary, the current region is Chiba. If there is, “Sawara” is output from the regional kana-kanji conversion dictionary, so that it can be displayed in the order of “Sahara, Sunahara, Sakai, Sawara”.

  Furthermore, the mobile terminal search device according to the present invention can be realized by a computer and a program, as well as by hardware. The program is provided by being recorded on a computer-readable recording medium such as a magnetic disk or a semiconductor memory, and is read by the computer when the computer constituting the portable terminal is started up, and the computer is controlled by controlling the operation of the computer. Functions as a control unit in each of the above-described embodiments and examples, and executes the above-described processing.
