Method of transmitting telephone number in wireless local loop system

Abstract

A method of transmitting a telephone number in a wireless local loop (WLL) system is provided for allowing a user to instantly hear a ring back tone by immediately performing a dialing in a WLL terminal when a flash signal is input by the user operating a hook switch after a telephone number is dialed in an ordinary telephone connected to the WLL terminal. The method checks the state of a hook switch of the ordinary telephone connected to the WLL terminal. When an off-hook sate is determined, it is determined whether a telephone number is input. When it is determined that a telephone number is input, the telephone number is stored in a dial buffer. It is continuously checked whether a flash signal is input while the input telephone number is being stored in the dial buffer. When the flash signal is input, the telephone number stored in the dial buffer is transmitted to the WLL system base station.
