SUBSCRIBER RADIO CONNECTION DEVICE AND ORIGINATING TREATING METHOD USING THE SAME IN WIRELESS LOCAL LOOP

摘要

PURPOSE: A radio connection device transmits its own dial tone to a terminal equipment of a subscriber immediately after the subscriber originates, and an originating treating method is provided to detect a dial tone transmitted from a switching system to treat the originating appropriately according to the circumstances of a traffic route. CONSTITUTION: When a terminal equipment(10) is hook-off, a subscriber radio connection device(20) transmits its own dial tone to the terminal equipment. The radio connection device analyzes a dual tone multi frequency signaling transmitted from the terminal equipment and store in a dial buffer. In addition, the radio connection device stops transmitting the dial tone to the terminal equipment and detects a dial tone of a switching system(50). After detecting the dial tone of the switching system, the radio connection device transmits the dual tone multi frequency signaling to the switching system according to the circumstances of the dial buffer. Therefore, a delay of dial tone in a wireless local loop system is shortened, and abnormal call connection is prevented.
