PURPOSE: A method for operating a wireless public telephone system using a Bluetooth is provided to replace an existing public telephone through a public network access point, installed in a public place, using a portable phone having a Bluetooth function. CONSTITUTION: A wireless public telephone system using a Bluetooth includes a portable terminal(11), a public network access point(12), a communication network(13), a local exchange(14), and an intelligent network(15). The portable terminal(11) contains a Bluetooth function. The public network access point(12), in which many Bluetooth modules are installed so that many persons can make telephone calls at the same time, enables the connection between a Bluetooth terminal and the communication network(13). The local exchange(14), in which a VoDSL(Voice of Digital Subscriber Line) line is installed, executes a function to connect the public network access point(12) with the intelligent network(15). The intelligent network(15) authenticates a wireless PSTN user and transfers authenticated/rejected information to the public network access point(12) through the local exchange(14).
