Definitions

  • This invention relates to a method and apparatus for searching a name from a personal information database, in particular, to a method and apparatus for searching a name from a directory in a mobile phone, and a radiocommunication terminal using the same.
  • a computer or personal digital assistant can comprise various kinds of personal information databases each of which generally consists of names and special data corresponding thereto such as telephone numbers, addresses, e-mail addresses, comments, etc.
  • a mobile phone also comprises at least one directory.
  • a directory consists of entries each containing a person's name and his telephone number.
  • a person's name consists of a family name, a first name and an optional middle name.
  • a user may obtain one's telephone number by searching the corresponding name from a directory.
  • Many methods have been proposed for name search.
  • One prior search method is to input a string which stands for a person's name. By comparing the input string with the names of all the entries in a directory, a matched entry will be searched out, and then the corresponding telephone number can be displayed on a screen.
  • numeric key 2 stands for A, B and C; 3 for D, E and F; 4 for G, H and I, 5 for J, K and L; 6 for M, N and O; 7 for P, Q, R and S; 8 for T, U and V; and 9 for W, X, Y and Z.
  • numeric key 2 stands for A, B and C; 3 for D, E and F; 4 for G, H and I, 5 for J, K and L; 6 for M, N and O; 7 for P, Q, R and S; 8 for T, U and V; and 9 for W, X, Y and Z.
  • the user has to input a long string to search a name.
  • the user has to input more information than what is needed.
  • This search method is not quick and convenient in the aspect of inputting. But, the search method has an advantage in the matching aspect. As soon as a string is completely input, an entry which has the same name as the input string is matched and displayed on the screen. The search method is quick and convenient in the matching aspect.
  • a second name search method the user only needs to press a single numeric key. Then, the mobile phone will search out all the entries in which first letters of the names are in relation to the pressed numeric key. In this method, the operation of inputting is simplified. However, in most cases, more than one entry can be searched out because of the facts that one numeric key stands for 3 or 4 letters and persons may have the same first letters in names. For instance, if the user presses numeric key "4", the names such as "Guo QingZhong”, “Guo Ping”, “HALL Randy”, “ILAN David” may be displayed on the screen.
  • search methods are improved by trading off between the above- mentioned two extreme methods.
  • a third search method when a first letter is input, the names having the family names of the directory beginning with the first input letter are displayed.
  • a second letter is input, the names having the family names of the directory beginning the two input letters are displayed. The more the letters are input, the more exact will be the displayed first names. With this method, it is not necessary to input all of the letters of the names to be searched before the right name is found.
  • a fourth search method called a predictive input method.
  • a search is done in a directory with the pressed letters.
  • One candidate having the most possibility to be represented by the pressed keys is then proposed. If the candidate is correct, the user can validate it. If not, the user has to continue to press more keys. The more letters the user inputs, the more exact will be the candidate. With this method, it is also not necessary to input all of the letters of the names to be searched before the right name is found.
  • the use may press the key "7" first, then “PC” is displayed; further press “2”, then “PC” is displayed; further press “8”, then “SAT” is displayed; further press “3”, then “save” is displayed; further press “6”, then “patent” is displayed.
  • the letters must be input in turn. In other words, the user can not input the letters of the family name until the letters of the first name have been input. If there are several same family names in the directory, the user still has to choose or continue to press keys. The number of the pressed keys is still relatively large.
  • An object of the invention is to provide a name search method, which can reduce the number of the pressed keys while keeping a high matching accuracy and efficiency.
  • Another object of the invention is to provide a name search apparatus for implementing the name search method of the present invention.
  • Still another object of the invention is to provide a radiocommunication terminal using the name search method and apparatus of the present invention.

Abstract

La présente invention concerne un procédé et un appareil permettant de rechercher un nom dans une base de données personnelle. On saisit en séquence au moins la première lettre d'un nom de famille, un caractère prédéterminé et au moins la première lettre d'un prénom. Une chaîne de recherche est mise à jour chaque fois qu'une nouvelle lettre est saisie. Les lettres précédant le caractère prédéterminé sont comparées avec les nom de familles de la base de données, et les lettres qui suivent le caractère prédéterminé sont comparées avec les prénoms de la base de données. Avec ce procédé, on améliore l'efficacité de la saisie sans dégrader la précision de la recherche.
