BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless terminal having a speed dial function and a speaker phone function. In particular, the address of another address is displayed by a shortcut icon while the phone number of the corresponding address is displayed by the speed dial function. The present invention relates to a method for retrieving a telephone number and a method for easily turning on / off a speakerphone by a shortcut icon during a call.

In the following description, the wireless terminal includes both a cellular phone, a personal communication system (PCS), a personal data assistant (PDA), an international mobile communication-2000 (IMT2000) terminal, and the like. I mean.

Typically, the wireless terminal has a speed dial function and a speaker phone function. Here, the speakerphone function is a function of performing a call using a speaker attached to a wireless terminal, not a handset. The speed dial function is a function of directly dialing (dialing) a specific phone number among phone numbers registered in an address book (or phone book) by inputting a shortcut key (or a numeric key).

When performing the speed dial function, the user inputs the address of a specific telephone number registered as a speed dial. Then, the name and phone number stored in the address are displayed on the screen (LCD screen) on the wireless terminal. Conventionally, when a user inputs a scroll key (usually a volume up / down key) to search for another phone number while the phone number of the corresponding address is displayed, the speed dial list is displayed. The item is not inquired and the key tone is adjusted. That is, even if the user wants to search for another phone number, the user cannot search for another phone number.

Therefore, in order to make a call to another address using the speed dial screen, it is inconvenient to press menu several times and follow the menu tree structure. To set up, a separate speakerphone icon must be designed on the screen, which is difficult to implement due to lack of adequate space. These problems can be solved by designing the speed dial icon and speakerphone icon on the screen of the wireless terminal. That is, the speed dial mode and the speakerphone mode are clearly distinguished, and the icon can be easily switched between modes. In addition, while executing the speed dial mode, the scroll key (volume up / down key) can function as a phone number search key instead of a key tone control key.

Accordingly, an object of the present invention is to provide a method for switching a speakerphone mode by using a shortcut key during a call in a wireless terminal. Another object of the present invention is to provide an icon for switching the operation of the speakerphone while performing a speakerphone function in a wireless terminal.
