ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a radio communication apparatus for use with a mobile station of a radio communication system.
2. Description of the Related Art
In recent years, a digital mobile communication system has provided a character data service for allowing communication terminals to exchange character data. Each communication terminal has a key input portion and a display portion (such as a liquid crystal display). With the input portion of the communication terminal on the transmission side, the user can input a desired message as a character string code. The message being input is displayed on the display portion. In the communication terminal on the reception side, the received character string code is converted into character data and displayed on the display portion.
When a message described in English is communicated, a space is placed between each word. A message is communicated as a character string code including space codes between each communication terminal. Thus, as shown in
FIG. 11
, a character string that composes one word may be displayed on two lines. To prevent a word from being divided, the transmission side may manually add a required number of space codes to a character string code. However, such a method results in increasing work. In addition, the number of characters displayed on the display portion may vary in each terminal unit. Moreover, when a communication is broken due to a deterioration of a radio communication environment such as fading, to minimize the length of communication data, it is undesirable to use space codes to fill in a line.
As another method, control codes may be placed in a character string code. However, in this method, since the communication data becomes long, this method is not proper.
Thus, since it is preferable to minimize the length of the communication data transmitted between communication terminals, it is preferable that a communication message is composed of only character codes. However, in this case, since a character string that composes a word as in English is often displayed on two lines, the user cannot easily see the resultant message.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a radio communication apparatus that prevents each word of a message received as a character string from being displayed on a plurality of lines so that the user can easily see the message.
Another object of the present invention is to provide a radio communication apparatus that allows the user to easily see a message without need to add a control code for a line feed process and a dummy space for a line to a character string that composes a message.
To accomplish the above-described object, the present invention is a radio communication apparatus, comprising a receiving means for receiving a radio signal transmitted from a base station, the radio signal including character codes, a display portion for displaying characters corresponding to character codes received by the receiving means on a plurality of lines, a detecting means for detecting a particular character from the character codes received by the receiving means, and a display controlling means for displaying word just before the particular character on one line of the display portion and a word just after the particular character on the next line of the display portion.
The particular character is a character that represents a delimiter of two character strings that compose respective words.
When said detecting means has detected the particular character, the display controlling means displays the character just after the particular character at the beginning of the next line.
According to the present invention, since each word of a message composed of a received character string is prevented from being displayed on a plurality of lines, the user can easily see a character string on the screen of the display portion. In addition, since it is not necessary to add a dummy space and a control code for a line feed process to transmission data, a character string can be transmitted with a short data length in a format that the user can easily see data.
These and other objects, features and advantages of the present invention will become more apparent in light of the following detailed description of a best mode embodiment thereof, as illustrated in the accompanying drawings.
